[75%, 100%] window - register it in NewScheduler (operator mode) --- operator/duties/beacon_adapter.go | 6 ++ operator/duties/ptc_attestation.go | 126 +++++++++++++++++++++++++++++

One duty per upcoming proposal slot — each operator builds the preference from its own beacon node, freezes it, signs under DOMAIN_PROPOSER_PREFERENCES (domain epoch = epoch(proposal_slot)), and a per-validator signature reconstructs only over byte-identical preferences. - duty.Slot = msg.Slot = proposal_slot, no emission-slot override: the base runner keys validatePartialSigMsg, verifyExpectedRoot's domain epoch, and messageEarliness off DutySlot, and the wire signature is under epoch(proposal_slot).

Make ProposerPreferences partial signatures converge cross-operator. Mechanical arms mirror PTC: validRoleAtSlot (Gloas-gated), partial-sig type<->role match + valid-type set, the pre-consensus seen-type limit, and the no-consensus-message rejection. The role also needs the per-signer state machine reconciled to its model — a signer holds preferences for its whole proposer lookahead at once, which the machine (built for monotonic one-slot-at-a-time advancement) did not fit: - messageEarliness allowance = the lookahead span (2 epochs), since a preference rides its future proposal slot. - Exempt the role from the monotonic ErrSlotAlreadyAdvanced check (monotonicSlotRole): else a higher proposal slot poisons the signer's lower ones, frequent on small networks where a validator proposes often. - messageLateness past bound, replacing the replay protection the exemption drops. - Size the per-signer ring to the lookahead (storedSlotCount) so concurrent lookahead slots don't collide and per-slot dedup stays exact. Accepted window is now bounded both ways: [proposal_slot - ~2, + 2 epochs]. 7 unit tests. A per-epoch dutyLimit and a dutyStore-backed duty-assignment check remain as future spam-hardening. --- message/validation/common_checks.go | 28 ++++- message/validation/consensus_validation.go | 6 +- message/validation/const.go | 5 + message/validation/partial_validation.go | 15 ++- .../validation/proposer_preferences_test.go | 112 ++++++++++++++++++ message/validation/seen_msg_types.go | 2 +- message/validation/signed_ssv_message.go | 2 +- message/validation/validation.go | 13 +- 8 files changed, 173 insertions(+), 10 deletions(-) create mode 100644 message/validation/proposer_preferences_test.go diff --git a/message/validation/common_checks.go b/message/validation/common_checks.go index 31059c8528..083f4192f7 100644 --- a/message/validation/common_checks.go +++ b/message/validation/common_checks.go @@ -15,8 +15,17 @@ func (mv *messageValidator) committeeRole(role spectypes.RunnerRole) bool { return role == spectypes.RoleCommittee || role == spectypes.RoleAggregatorCommittee } +// monotonicSlotRole reports whether a role's signer advances through slots one at a time, so a message +// for a slot below the signer's max is stale and must be rejected.

The QBFT plumbing is generic over spectypes.Encoder / ssv.ValueChecker, so only the value type and its checker (NewGloasVoteChecker) differ per fork. Decode is made fork-aware at every seam: the consensus decode prototype, the post-consensus expected-roots decode, and — caught in review — the post-consensus partial-sig validation in runner_validations.go, which decoded BeaconVote and would otherwise reject every Gloas post-consensus signature so attestations never aggregate. decidedAttestationVote (replacing beaconVoteFromEncoder) extracts the common BeaconVote plus the index as a *phase0.CommitteeIndex — non-nil only on Gloas — which constructAttestationData uses to override the Electra index=0. The fork gate is IsGloas (BeaconForkAtEpoch caps at Fulu). The sync-committee path is untouched (it reads only BlockRoot). Message validation needs no change: it hashes raw FullData and never decodes the vote type. --- protocol/v2/ssv/runner/committee.go | 81 +++++++++++++------ protocol/v2/ssv/runner/committee_test.go | 13 ++- protocol/v2/ssv/runner/runner_validations.go | 15 +++- protocol/v2/ssv/runner/type_assertions.go | 38 ++++++--- .../v2/ssv/runner/type_assertions_test.go | 35 ++++++-- 5 files changed, 132 insertions(+), 50 deletions(-) diff --git a/protocol/v2/ssv/runner/committee.go b/protocol/v2/ssv/runner/committee.go index 0eb032dc03..f23e365b81 100644 --- a/protocol/v2/ssv/runner/committee.go +++ b/protocol/v2/ssv/runner/committee.go @@ -33,6 +33,7 @@ import ( "github.com/ssvlabs/ssv/protocol/v2/qbft/controller" "github.com/ssvlabs/ssv/protocol/v2/ssv" ssvtypes "github.com/ssvlabs/ssv/protocol/v2/types" + "github.com/ssvlabs/ssv/protocol/v2/types/gloas" ) type CommitteeDutyGuard interface { @@ -220,7 +221,16 @@ func (r *CommitteeRunner) ProcessConsensus(ctx context.Context, logger *zap.Logg span := trace.SpanFromContext(ctx) span.AddEvent("processing QBFT consensus msg") - decided, decidedValue, err := r.baseConsensusMsgProcessing(ctx, logger, r.ValCheck.CheckValue, msg, &spectypes.BeaconVote{}) + + // The decided value is a GloasBeaconVote (which carries the attestation index) on Gloas slots, a + // plain BeaconVote before.

Every caller passes its slot — the scheduler attestation timer and head-event acceleration check, the attester/proposer indices-change deadline, the aggregator-committee runner, and the goclient aggregator and sync-contribution waits — so each lands on the right quarter automatically.

charset=UTF-8 Content-Transfer-Encoding: 8bit The spec ProposerConsensusData.Version is a spec.DataVersion that can't represent Gloas, and its GetBlockData/Validate reject unknown versions, so the Gloas proposer path bypasses the spec block decoder at every site, gated on IsGloas(slot) with networkconfig.DataVersionGloas as a fail-safe value marker (a missed spec call-site errors out rather than mis-decoding): - ProcessPreConsensus produces via GetGloasBeaconBlock and wraps the block SSZ directly — the ePBS block is bid-only (the payload ships in the §6 envelope), so there is no blinding. - ProcessConsensus and expectedPostConsensusRootsAndDomain decode the block node-side; the block doubles as the ssz.HashRoot the proposer signs. - ProcessPostConsensus content-matches the decided value against this operator's cached block: only the operator that built it publishes (it alone can reveal the matching payload in the envelope), while the others complete the duty without submitting. This replaces the leader-ID check, which could miss the holder after a round change. - value_check.go validates the value and reads the slashing slot via the node-side decode. Shared post-submit bookkeeping is factored into finishSubmittedProposal. Adds gloas.DecodeBeaconBlock and a shared gloas.TestingBeaconBlock fixture; covered by value-check and runner content-match tests. --- protocol/v2/ssv/runner/proposer.go | 220 ++++++++++++++++++------ protocol/v2/ssv/runner/proposer_test.go | 115 ++++++++++++- protocol/v2/ssv/value_check.go | 35 +++- protocol/v2/ssv/value_check_test.go | 58 +++++++ protocol/v2/types/gloas/beacon_block.go | 11 ++ protocol/v2/types/gloas/testing.go | 22 +++ 6 files changed, 393 insertions(+), 68 deletions(-) create mode 100644 protocol/v2/types/gloas/testing.go diff --git a/protocol/v2/ssv/runner/proposer.go b/protocol/v2/ssv/runner/proposer.go index 38c07480ad..21c77f0127 100644 --- a/protocol/v2/ssv/runner/proposer.go +++ b/protocol/v2/ssv/runner/proposer.go @@ -21,6 +21,7 @@ import ( "github.com/ssvlabs/ssv/ssvsigner/ekm" + "github.com/ssvlabs/ssv/networkconfig" "github.com/ssvlabs/ssv/observability" "github.com/ssvlabs/ssv/observability/log/fields" "github.com/ssvlabs/ssv/protocol/v2/blockchain/beacon" @@ -29,6 +30,7 @@ import ( "github.com/ssvlabs/ssv/protocol/v2/qbft/controller" "github.com/ssvlabs/ssv/protocol/v2/ssv" ssvtypes "github.com/ssvlabs/ssv/protocol/v2/types" + "github.com/ssvlabs/ssv/protocol/v2/types/gloas" ) type ProposerRunner struct { @@ -58,6 +60,11 @@ type ProposerRunner struct { // cachedBlindedBlockSSZ is a fingerprint of the cachedFullBlock, it is stored here // for efficient validation (so we re-use it instead of re-calculating). cachedBlindedBlockSSZ []byte + + // cachedGloasBlockSSZ holds the SSZ of the Gloas (ePBS) block this operator fetched for the duty. + // Post-consensus content-matches it against the decided value to detect whether this operator + // built the decided block — only that operator publishes it (and can later reveal its payload). + cachedGloasBlockSSZ []byte } // ProposerRunnerOptions bundles all dependencies required by NewProposerRunner. @@ -171,63 +178,106 @@ func (r *ProposerRunner) ProcessPreConsensus(ctx context.Context, logger *zap.Lo // Fetch the block our operator will propose if it is a Leader (note, even if our operator // isn't leading the 1st QBFT round it might become a Leader in case of round change - hence // we are always fetching Ethereum block here just in case we need to propose it). - start := time.Now() - vBlk, _, err := r.GetBeaconNode().GetBeaconBlock(ctx, duty.Slot, r.graffiti, fullSig) - if err != nil { - return fmt.Errorf("get beacon block: %w", err) + var input *spectypes.ProposerConsensusData + if r.NetworkConfig.IsGloas(r.NetworkConfig.EstimatedEpochAtSlot(duty.Slot)) { + input, err = r.gloasProposalInput(ctx, logger, duty, fullSig) + if err != nil { + return err + } + } else { + start := time.Now() + vBlk, _, err := r.GetBeaconNode().GetBeaconBlock(ctx, duty.Slot, r.graffiti, fullSig) + if err != nil { + return fmt.Errorf("get beacon block: %w", err) + } + // Log essentials about the retrieved block. + logFields, proposalTraceAttrs := proposalCommonFields(vBlk) + logFields = append( + logFields, + zap.Duration("proposer_delay", r.proposerDelay), + fields.Took(time.Since(start)), + ) + + feeRecipient, err := vBlk.FeeRecipient() + if err != nil { + logFields = append(logFields, zap.NamedError("feeRecipient_err", err)) + } else { + logFields = append(logFields, fields.FeeRecipient(feeRecipient[:])) + } + const eventMsg = "🧊 got beacon block proposal" + logger.Info(eventMsg, logFields...) + span.AddEvent(eventMsg, trace.WithAttributes(proposalTraceAttrs...)) + + // Ensure we propose a blinded block in QBFT.

QBFT round timer: round1HeadStart now derives from IntervalDuration (committee 1x, aggregator/sync 2x) instead of slotDuration/3, so the head starts follow the retimed attestation/aggregate deadlines under Gloas. RoundTimeout and EstimatedRoundAt (plus the message-validation round-spread check) pass IntervalDuration(slot). Pre-Gloas behavior is byte-identical (interval = slotDuration/3). QuickTimeout stays a fixed 2s round-trip budget -- under the tighter Gloas deadline the proposer is effectively round-1-must-succeed, a deliberate choice pending devnet round-trip data. - ProposerDelayEPBS: a new fork-gated knob. ProposerDelay (and its dangerous override) applies pre-Gloas only; ProposerDelayEPBS applies from the Gloas fork on, hard-capped at 1s with no override and default 0 -- the safe ranges differ under the tighter deadline.

So **T7/T10 extend those, they don't author wrappers.** **`boole-fork` has not yet landed on stage** (stage is still `ssv-spec v1.2.2` / `SSVForks struct{}`; `boole-fork` is ~46 commits behind stage, tip Apr 2026) — but it's **expected to merge within ~2-3 weeks (≈ mid-July 2026), treated as ground truth** (see §2b). The build baseline is **`boole-fork`** (verify anchors against it). **Decision: ePBS starts now off `boole-fork`** — it must begin immediately for independent development + testing (against T2 mocks/devnet, which doesn't gate on Boole landing), so it can't wait for the merge; it rebases onto stage when Boole lands (~2-3 weeks) — see §6. The pre-Boole HEAD pin (`82a9f4f8f`) and §0/U findings are pre-Boole; corrections are inline where they flip (U0/U5/T7/T10/T11). + +**Scope:** the `ssv` node (this repo). All new protocol types are added **node-side** — aligned with the team decision to **migrate off ssv-spec imports entirely** (end-state). ePBS adds its types node-side and must not deepen ssv-spec coupling, but does **not** execute the full migration (separate initiative — see U0). **Deviation (PTC, as built):** the ePBS wire **constants** (roles/domains/partial-sig types) were added to **ssv-spec via [PR #632](https://github.com/ssvlabs/ssv-spec/pull/632)** — the established `spectypes` pattern, and required because ekm/ssvsigner reaches signing domains only through `spectypes` (a separate module that can't import node-side gloas); the node-side `protocol/v2/types/gloas` package holds only the **wire types**. The SIP remains the canonical wire source. Upstream-unmerged beacon APIs are **abstracted behind interface methods and mocked now**, swapped when upstream stabilizes. + +**Source pins (re-verify at implementation start — the spec is still pre-final):** +- Consensus specs: `ethereum/consensus-specs@6ebb2216c` (Gloas) +- The SIP's own text: [ssvlabs/SIPs#94](https://github.com/ssvlabs/SIPs/pull/94) +- Beacon APIs: produceBlockV4 + envelope endpoints in [beacon-APIs#580](https://github.com/ethereum/beacon-APIs/pull/580) (open, head `bed49d98`); PTC + payload-attestation endpoints already tagged in `beacon-APIs@v5.0.0-alpha.2` + +**Non-goals / out of scope:** +- Anchor (Rust client) — coordinated separately; wire-level constants must match (see U0). +- Retiring `BeaconVote` / renaming `GloasBeaconVote` → `BeaconVote` — follow-up SIP, post-fork. +- The AggregatorCommittee consolidation refactor — **shipped by the Boole fork** (`boole-fork`), not ePBS; ePBS builds on the already-consolidated baseline (`RoleAggregatorCommittee=6`).

(Note: `builder_index` is *not* the validator index in self-build; the non-self-build branch reads a separate `state.builders[...]` registry.) + +**Node-side facts (resolved during research):** +- **No SSV `DomainType` bump needed for Gloas** (conclusion holds; pre-Boole basis corrected). Gloas is a **beacon** fork — gate it by beacon epoch via `Beacon.BeaconForkAtEpoch` (Boole's rename of `ForkAtEpoch`; see U5). The pre-Boole basis ("`SSVForks` is an empty struct") is now **false**: Boole made `SSVForks{ Boole phase0.Epoch }` and added a `DomainType`/`NextDomainType` rotation (`networkconfig/ssv.go`). But those are **SSV-fork** (Boole) concerns, distinct from beacon forks, and the Gloas signing domains (`0x0B/0C/0D`) are beacon-side — so the SSV `DomainType` is untouched. Open at T1: whether Gloas also wants an `SSVForks` entry now that the machinery exists, or stays purely beacon-epoch-gated (default: beacon-epoch — it's beacon-driven). +- **Slashing protection needs no change.** Double-vote/surround detection compares **only `Source.Epoch`/`Target.Epoch`** — eth2-key-manager's `NormalProtection.IsSlashableAttestation` (reached via `ssvsigner/ekm/slashing_protector.go`) never inspects `index`, and by design doesn't even store signing roots. The full `AttestationData` is SSZ-persisted (`ssvsigner/ekm/signer_storage.go`), but only the source/target epochs are ever read for the slashable check — so the Gloas `index` semantics change is irrelevant to slashing, not because `index` is now part of the compared data but because it never was. The only index-aware work is in the value-check construction (T4). +- **A second concurrent QBFT instance for the same (validator, slot) is cleanly supported.** The two roles stay separate: message-validation consensus state and validation locks are keyed by `MessageID` (which includes `RunnerRole`), and runner queues by `RunnerRole` — so EnvelopeProposer (§6 QBFT variant) won't collide with the proposer's block QBFT. **Caveat:** this isolation holds on the per-validator runner path (`protocol/v2/ssv/validator/validator.go`, role-keyed `Queues`); the Committee path keys queues by **slot** (`committee.go`), not role. The three new roles must therefore be wired as per-validator runners, never onto the committee path (see T10). +- **The shared Gloas vote is inert for sync-committee duties.** The committee runner's sync path reads only `BeaconVote.BlockRoot` (`committee.go` sync-message construction); adding `AttestationDataIndex` to the vote doesn't touch it. +- **`api.VersionedProposal.Blinded`** is the local-vs-builder signal (already logged via `BeaconBlockIsBlindedAttribute`) — the basis for the U6 local-build metric. + +**Dependency landscape (resolved):** +- **go-eth2-client has no Gloas types** — neither the SSV fork (`v0.6.31-…`, based on upstream v0.27.0) nor upstream master (`v0.28.1`). No `DataVersionGloas`, no `spec/gloas` package. → the fork must be patched (U2). +- **ssv-spec has no Gloas work** (no branch/PR). The **AggregatorCommittee consolidation is now the baseline** — Boole bumps the node to `ssv-spec v1.2.3-pseudo` (`RoleAggregatorCommittee=6`; deprecated `RoleAggregator=1`/`RoleSyncCommitteeContribution=3` gaps), so the pre-Boole "`v1.2.2` contiguous/pre-consolidation" framing no longer applies. → U0. + +--- + +## 1.

Line numbers are approximate (`~`) and may drift. +- Each new runner role touches five seams: **(a)** type/enum, **(b)** runner impl, **(c)** `SetupRunners` registration, **(d)** duty handler/trigger, **(e)** message validation. + +--- + +## 2. Resolved investigations (findings + decisions) + +### U0 — How the new protocol types enter the node **(decided — incl. the ssv-spec posture)** +**Findings:** +- The new wire constants (roles, partial-sig types, domains, `GloasBeaconVote`, `EnvelopeConsensusData`, `BlindedExecutionPayloadEnvelope`) **do not exist in canonical ssv-spec** — there's no Gloas branch/PR. SSV must author them regardless of bump-vs-copy. +- ssv-spec's AggregatorCommittee consolidation is now **the baseline** — it lands in stage via the **Boole** fork (`ssv-spec v1.2.3-pseudo`). ePBS builds **on top of** the consolidated roles; the old "decouple an unreleased refactor" framing is obsolete. +- Wire values are protocol-canonical and must match Anchor; the **SIP (not an ssv-spec PR) is the canonical wire source**. + +**Decision/recommendation:** +- **The consolidation is the Boole baseline, not an ePBS prerequisite** — ePBS builds on it (shipped via `boole-fork`); it never owns or bumps it. +- **Add the Gloas types in-tree now** (e.g. a `gloastypes` package), using the SIP's canonical values: `RunnerRole` PTC=7/Prefs=8/Envelope=9; `BeaconRole` 7/8/9; `PartialSigMsgType` `PTCAttesterPartialSig`=7, `ProposerPreferencesPartialSig`=8 (+ `EnvelopePartialSig`=9 only if U1 picks no-QBFT); domains `0x0B/0x0C/0x0D`. These slot cleanly above the now-baseline consolidated max (`RoleAggregatorCommittee=6`), verified against post-Boole `ssv-spec v1.2.3-pseudo`. (Wire values verified against SIP #94: roles 7/8/9, partial-sigs 7/8, domains `DomainBeaconBuilder=0x0B`/`DomainPTCAttester=0x0C`/`DomainProposerPreferences=0x0D`; the SIP reserves RunnerRole 1/3 for pre-consolidation back-compat decoding.) +- **Extend Boole's existing node-side switches — don't author new wrappers.** Boole already moved both switches node-side (for its own consolidation back-compat): `protocol/v2/types/consensus_data.go` version-switches extraction over `spectypes.ProposerConsensusData` (the `getBlockData` seam), and `protocol/v2/types/runner_role.go`'s `RunnerRoleForValidatorDuty(duty, isBooleFork)` is the fork-aware duty→role map (replacing `spectypes.MapDutyToRunnerRole` node-side). So T7 adds a `DataVersionGloas` arm to `consensus_data.go`, and T10 adds the three new roles + an `isGloas` branch to `RunnerRoleForValidatorDuty` (mirroring its existing `isBooleFork` shape). The "wrappers" are extension points already in-tree — and already the migration seams. **Parameterizes T7, T10.** +- **Lock the Anchor wire constants early, not at end-of-execution.** They're already in the SIP (roles 7/8/9, partial-sigs 7/8, domains `0x0B/0C/0D`) and isolated — so confirming them with Anchor is *cheap now* and *expensive to discover wrong at interop*. Isolation makes them cheap to lock early, not a reason to defer. Proceed with the SIP-canonical values and get Anchor's explicit ack up front (against the SIP — the canonical wire source, no ssv-spec PR) rather than deferring to the end (see §2b). + +**ssv-spec posture (decided): migrate off ssv-spec imports entirely** (end-state). ePBS runs in the pragmatic fallback: **define the new types we need node-side; never modify, bump, or PR ssv-spec.** Guiding principle for every track — *do not deepen ssv-spec coupling*: new types are node-side; existing ssv-spec types are extended (node-side constants of the existing type) or wrapped, never edited; any node-side type that mirrors an ssv-spec one stays **SSZ/wire-identical** through the hybrid phase. The consolidation shipped via Boole's ssv-spec bump (`v1.2.3`) and is the baseline; ePBS neither bumps nor owns it. **Parameterizes T1, T7, T10, and all role work.** + +**Relationship to the full migration:** owning *all* duty-related types node-side (`ValidatorConsensusData`/`BeaconVote`/duty/role/value-check, `MessageID`, the QBFT types, …) is a **separate, larger initiative** — out of scope here. ePBS is its **first down-payment**: the Gloas types land node-side, and the wrappers (T7/T10) are the seams the migration will later cut. That migration's main cost is **spectest decoupling** (the node runs ssv-spec test vectors) — but ePBS doesn't pay it: Gloas has no ssv-spec vectors, so the new node-side types don't disturb existing spectest compatibility. Forward-compat: the Gloas role/partial-sig constants are values of the *existing* `spectypes` base types for now, and move wholesale when those base types are reimplemented node-side. Note: nothing in ePBS *forces* an ssv-spec edit — QBFT is value-agnostic (a new instance over `BlindedExecutionPayloadEnvelope` needs only a node-side value-check), and `MessageID` is reused read-only with node-side role values. **Steady-state caveat (largely moot post-Boole):** the duty→role / consensus-data switches T7/T10 extend are **already in-tree as Boole's** (`runner_role.go`/`consensus_data.go`), serving Boole's own consolidation back-compat — so they're load-bearing regardless of whether the ssv-spec migration ever runs. Only `gloastypes` is genuinely ePBS-introduced, and it's a clean node package fine to live with permanently. + +### U1 — §6 envelope distribution: QBFT vs no-QBFT(sign-all) **(RESOLVED — QBFT; SIP #94 maintainer call, 2026-06-23)** +**Decision: QBFT** — keep the SIP's prescribed shape (a second QBFT round over the blinded envelope; **no** new `PartialSigMsgType` — post-consensus reuses `PostConsensusPartialSig`, role discriminates routing). GalRogozinski on the §6 thread ([r3460315536](https://github.com/ssvlabs/SIPs/pull/94#discussion_r3460315536)): *"QBFT is the correct call for now. It handles the faulty leader edge case. The way forward is for later SIPs to reduce the QBFT timeout. Eventually we need a more suitable consensus algo."* This **overrules** the earlier node-side recommendation (no-QBFT sign-all). What carried it (shane-moore's surface argument, [r3364710775](https://github.com/ssvlabs/SIPs/pull/94#discussion_r3364710775)): the no-QBFT path's real cost is a **new top-level network message class** — a dissemination carrier for the `BlindedExecutionPayloadEnvelope` plus a new `EnvelopePartialSig` kind — touching the message-validation dispatch, a new validated-message variant, receiver routing, and byte-compat across every client (go-ssv, Anchor, future). QBFT reuses existing consensus machinery with **no new message class** and the default round-robin leader; its degeneracy (a round-changed envelope leader ≠ block proposer) is mild given the ~6s budget from the 25% block deadline to the 75% payload-due cutoff. The latency/Byzantine edge for no-QBFT was judged not to outweigh that surface for a path expected to be rare (local-build ~0.1–2%). **Contained to T8 (ships last).** T8 builds the QBFT variant only; the no-QBFT design is retired (kept for history). + +### U2 — go-eth2-client Gloas support + beacon API maturity **(decided)** +**Findings:** +- Gloas is absent from both the SSV fork and upstream — **there is nothing to bump to**. +- produceBlockV4 confirmed: response is `anyOf [Gloas.BeaconBlock, Gloas.BlockContents]` (per #580 head — `anyOf`, not `oneOf`; no blinded-block variant post-Gloas), discriminated by the `Eth-Execution-Payload-Included` header (+ `Eth-Consensus-Version: gloas`); SSZ or JSON. Envelope POST (`publishExecutionPayloadEnvelope`) accepts `SignedExecutionPayloadEnvelopeContents` (stateless) **or** bare `SignedExecutionPayloadEnvelope` (stateful); envelope GET returns `Gloas.ExecutionPayloadEnvelope`. +- **Endpoint maturity tiers:** + - **Merged/tagged** (lower risk): PTC duties, `payload_attestation_data`, `payload_attestations` pool — in `beacon-APIs@v5.0.0-alpha.2` and master. + - **Unmerged** (pin to #580, expect churn): produceBlockV4, envelope POST/GET, `types/gloas/{block_contents,execution_payload_envelope}`. + - **Nonexistent** (fully abstract, no real BN to test against): validator-facing `SignedProposerPreferences` publication. + +**Decision (revised — full node-side implementation; supersedes the earlier mock-only stance):** build the Gloas beacon surface node-side **now** — full-fidelity SSZ/JSON types (BeaconBlock/BlockContents, ExecutionPayloadEnvelope + Contents, PayloadAttestation/Data/Message + PTCDuty, ProposerPreferences/Signed) **and** hand-rolled HTTP endpoint clients — not abstract-and-mock-only. Rationale: a multi-client Glamsterdam/Gloas devnet is **live** (since ~May 2026), so a *real* implementation can be e2e-tested against a local devnet (see T12 / ssv-mini); mock-only can't be. Mocks are kept, but only for unit tests. The go-eth2-client rebase is now a **later dedup** — swap our node-side types/clients for upstream's `spec/gloas` when it ships — **not** a prerequisite or a gate. Types/endpoints are `#580`-pinned and will churn → watch + iterate. (`SignedProposerPreferences` is the lone exception: no endpoint exists in any client, so it stays mock-only — see §2b.) **Parameterizes T2.** + +### U3 — `BeaconNode` interface diff + mocks **(decided)** +Add to `protocol/v2/blockchain/beacon/client.go` (mocks regen via `//go:generate mockgen` at `client.go:~15`): +- `PTCCalls`: `PTCDuties(epoch)`, `PayloadAttestationData(slot)`, `SubmitPayloadAttestations(...)` — merged endpoints. +- `ProposerPreferencesCalls`: `SubmitProposerPreferences(...)` — **no real endpoint yet; mock only**.

The wire signature is under `epoch(proposal_slot)`, so `DutySlot = proposal_slot` is **forced**, hence `msg.Slot = proposal_slot` (an emission-slot override would make every receiver drop the message as "slot already passed"). The future `proposal_slot` is instead permitted by a **bounded role-specific earliness allowance** in `messageEarliness` (T9) — not by runner slot-trickery. +- **Pre-fork acceptance:** message validation must accept `RoleProposerPreferences` for `~MIN_SEED_LOOKAHEAD` epoch(s) before `GLOAS_FORK_EPOCH` (fork-aware allow). This is net-new logic — there is **no existing ValidatorRegistration fork-cutoff in message validation to mirror**; both this pre-fork accept and the VR post-fork reject (T5) are new and must be built symmetrically. The gate to design around is `messageEarliness` (role-agnostic, no per-role exemption), which would otherwise reject a future-slot message. +- `dutyLimit` (`common_checks.go:~117`, whose `default` returns `(0, false)` — an *exists* flag the caller uses to skip the limit, not a numeric no-limit) and `messageLateness` (no `default` → unlisted role treated late just past slot-start) both need explicit arms for the three roles (`dutyLimit` arms returning `(limit, true)`). Note `validRole`/`partialSignatureTypeMatchesRole` **already** have arms for the non-QBFT roles (ValidatorRegistration/VoluntaryExit) — a clean template to copy; only `maxRound` (default→error) and `dutyLimit` (default→`(0,false)`) truly lack arms. +**Parameterizes T5, T6, T9.** + +### U5 — Fork-gating + slashing **(decided)** +**Findings/decisions:** +- **Gating:** beacon fork epochs are fetched at runtime from the BN's `/eth/v1/config/spec` (not node config). Wire Gloas by: adding `DataVersionGloas` (via the U2 fork patch), filling the `GLOAS_FORK_EPOCH` TODO in `beacon/goclient/spec.go` (**already present on stage at `spec.go:255`**), adding Gloas to the beacon fork-epoch method, and a node `IsGloas(slot/epoch)` helper. No per-network config-file changes. **Boole-baseline note (corrected):** `spec.go`/`networkconfig/beacon.go` are **not** rewritten by Boole — small diffs only (the GLOAS TODO + fork list pre-exist on stage, so these seams are *more* stable than feared). The one relevant change is the beacon fork method rename `ForkAtEpoch` → `BeaconForkAtEpoch` (`beacon.go:141` on `boole-fork`), done to disambiguate from Boole's new SSV-fork `BooleForkAtEpoch`.

Add the `IsGloas` helper and the `ForkAtEpoch` Gloas entry (`networkconfig/beacon.go`). `DataVersionGloas` comes from the T2 fork patch. **Placement (migration-aligned):** land `gloastypes` as a subpackage of the eventual bridge home `protocol/v2/types` (e.g. `protocol/v2/types/gloas`), not a standalone top-level package — so the ssv-spec migration absorbs it into one node-type root without a relocation, and its M1 codemod sweeps it like any other file (migration plan §1). On `boole-fork`, `protocol/v2/types` already hosts node-side `runner_role.go`/`consensus_data.go`/`partial_sig_message.go`, so `protocol/v2/types/gloas` sits beside real protocol-type siblings (placement A confirmed). Model `IsGloas` on the **beacon** fork method (`BeaconForkAtEpoch`), not the SSV-fork `BooleForkAtEpoch` (per U5/§0); `SSVForks` is no longer empty (it has `Boole`) — decide per §0 whether Gloas needs its own entry. + +### T2 — BeaconNode abstraction + full node-side Gloas types & endpoint clients **(needs U2, U3)** +Per U2 (revised — full impl): add the U3 interface methods to `client.go`; define **full-fidelity Gloas types node-side** (in the `gloas` package — SSZ + JSON per `consensus-specs@6ebb2216c` + beacon-APIs#580) and implement the `beacon/goclient/` **endpoint clients (real HTTP)** — not placeholders.

The go-eth2-client rebase later swaps our node-side types/clients for upstream's `spec/gloas` (a dedup), not a gate. *(`DataVersionGloas` placeholder + `IsGloas` and the `GLOAS_FORK_EPOCH` wiring already landed.)* + +### T3 — §1 slot timing **— done** (uncommitted) +The key realization: ePBS retimes duties from **thirds to quarters**, and every deadline is `N × IntervalDuration` with **N preserved across the fork** (attestation/sync 1×, aggregate/contribution 2×, PTC 3×); the Gloas bps (2500/5000/7500) are exactly 1/4, 2/4, 3/4. So the whole change is one fork-gate: `(*Beacon).IntervalDuration()` → `IntervalDuration(slot)`, returning `SlotDuration/3` pre-Gloas and `SlotDuration/4` from Gloas on. Every `N × IntervalDuration` caller then lands on the right quarter automatically — scheduler attestation timer (`SlotTicker`) + head-event acceleration check, attester/proposer indices-change deadline, the aggregator-committee runner, and `goclient` aggregator + sync-contribution. **Pre-Gloas is byte-identical** (`TestNetwork` has no Gloas). The misleadingly-named `waitOneThird*`/`waitTwoThirds*` helpers were renamed `waitOneInterval*`/`waitTwoIntervals*` with fork-aware comments/logs. PTC's 75% (`PayloadAttestationCutoff` = 3/4) was already correct — untouched. Unit test `TestBeacon_IntervalDuration` (thirds before the fork, quarters from it on). + +**QBFT round-1 head-start — deliberately not retimed (2026-06-27).** `roundtimer/timer.go`'s `round1HeadStart` (`slotDuration/3` committee, `*2/3` aggregator/sync-contribution — the pre-round-1 wait for the block/attestations to arrive) is the one timing constant *not* routed through `IntervalDuration`, so it stayed at thirds post-Gloas. It is QBFT round-change *liveness* timing, not one of the SIP §1 duty deadlines (all retimed above), so retiming it is out of §1 scope; the post-Gloas misalignment (head-start 1/3 vs the now-1/4 attestation deadline) only loosens leader-rotation timing on the slow path, with no correctness impact. **Decision: leave as-is** — revisit only if consensus timing proves problematic under the tighter ePBS schedule on devnet. (Surfaced by a §1 review.) + +### T4 — §2 attestation / `GloasBeaconVote` **(needs T1, T2, U5) — scoped against Anchor (2026-06)** +**The type already exists** (T1 built `protocol/v2/types/gloas/beacon_vote.go` — `GloasBeaconVote{BlockRoot, Source, Target, AttestationDataIndex}`, 120B SSZ, field-order- and wire-identical to Anchor's `GloasBeaconVote`), referenced nowhere outside its package. So **T4 is pure wiring**, not new types. + +**Anchor's `GloasBeaconVoteValidator` = the pre-Gloas validator + exactly two rules:** (1) range-check `attestation_data_index ∈ {0,1}` (reject ≥2); (2) reconstruct the slashing-check `AttestationData` with the single QBFT-decided index. Everything else (far-future target, source) }` and passes it to the proposer's `StartEnvelopeDuty`. `c.ExecuteDuty` enqueues (async) + routes by pubkey, and `RunnerRoleForValidatorDuty` → `duty.RunnerRole()` → `RoleEnvelopeBuilder` on Gloas (post-Boole) slots, so no role-map change was needed. + - **⑥ message validation — DONE** (committed): the role-9 arm across the validation rules — `validRoleAtSlot` (Gloas-only), `maxRound`=2 + the round-spread skip + `messageLateness` (all like the proposer — QBFT, instance-relative timing), `partialSignatureTypeMatchesRole` (post-consensus only, no pre-consensus), `dutyLimit`=SlotsPerEpoch (≤1 self-build envelope/slot). `committeeRole`/`monotonicSlotRole`/`validateBeaconDuty`/`storedSlotCount` unchanged — not a committee role, not beacon-scheduled, has consensus. Per §0 no infra change (state is `MessageID`-keyed, incl. `RunnerRole`). 5 unit tests. + - **Heavy payload — DONE** (committed): the full Gloas `ExecutionPayload` (Deneb's + `block_access_list` [EIP-7928 — an opaque `ByteList`, *not* the feared nested SSZ: the EL RLP-encodes it, the CL only stores+hashes] + `slot_number` [EIP-7843]; `base_fee_per_gas` as `[32]byte` SSZ uint256), the full `ExecutionPayloadEnvelope`/`SignedExecutionPayloadEnvelope` + a `Blinded()` transform, and goclient `Get`/`SubmitExecutionPayloadEnvelope` (best-effort #580 paths, octet-stream SSZ like §4). The runner's `produceBlindedEnvelope`/`submitEnvelope` are filled (fetch→cache→blind / content-match→holder publishes). **e2e QBFT test — done** (committed): `runner/envelope_e2e_test.go` adapts the proposer's heavyweight harness, covering the post-consensus publish both via direct `submitEnvelope` (builder publishes / competing-envelope operator skips) and a full `ProcessPostConsensus` (share-signed partial-sig quorum under `DOMAIN_BEACON_BUILDER` → reconstruct → publish). **HTR-parity — done** (committed): the `ExecutionPayload` field order, `BlockAccessList` bound (`ByteList[2**30]`), and `slot_number` placement were verified field-for-field against the canonical container (consensus-specs `specs/gloas/beacon-chain.md` @ `6ebb2216c`); `TestExecutionPayloadLayoutMatchesSpec` pins the HTR as a drift guard. **Deferred (devnet-gated):** the `…Contents` blob-carrying publish body — it carries `envelope + blobs + kzg_proofs`, but there's no blob source (T7 defers the §4 `BlockContents`; the proposer caches only the bare block `cachedGloasBlockSSZ`), the #580 publish endpoint accepts *either* the bare envelope (stateful — what SSV does, working) *or* the Contents (stateless), and SSV self-build is naturally stateful (its own BN built + holds the §4 payload). So the Contents form is needed only if a devnet BN runs payload-stateless — revisit then (it also un-defers T7's blob plumbing). **TODO** — a *computational* HTR cross-check against published canonical Gloas SSZ spec vectors once the fork ships (none exist for the unreleased fork yet, so today's check is against the spec *source* + a drift guard, not vectors). +- **Recommendation when resuming:** build ④ as the first focused step (consensus-critical — don't rush it at a session tail), then ⑤/⑥, then the heavy payload last (devnet-validated). + +### T9 — Message validation for new roles **(needs U4; pairs with T5/T6/T8)** +Implement the U4 rule arms: `validRole`, `partialSignatureTypeMatchesRole`, `dutyLimit`, `messageEarliness`/`messageLateness`, `maxRound`. Dual-instance needs **no infra change** (state is `MessageID`-keyed, per §0) — just add the role arms. + +**ProposerPreferences: done** (uncommitted). Mechanical arms mirror PTC (`validRoleAtSlot`=`isInGloas`, `partialSignatureTypeMatchesRole`, `validPartialSigMsgType`, pre-consensus limit, `seen_msg_types`, no-consensus reject). Plus the **multi-future-slot reconciliation** the role forced — its signer holds the whole lookahead at once, which the per-signer state machine (built for monotonic one-slot-at-a-time) didn't fit: (1) `messageEarliness` allowance = the lookahead span (`proposerPreferencesEarlyEpochs`=2 epochs); (2) **exempt from the monotonic `ErrSlotAlreadyAdvanced` check** (`monotonicSlotRole`) — else a higher proposal slot poisons lower ones (devnet-frequent); (3) **`messageLateness` past bound** (replaces the dropped monotonic replay protection); (4) **per-signer ring sized to the lookahead** (`storedSlotCount(role)`) so concurrent lookahead slots don't collide and per-slot dedup stays exact. 7 unit tests. +**Spam hardening: done** (uncommitted). Per-epoch `dutyLimit` arm (`SlotsPerEpoch`) + a duty-assignment check in `validateBeaconDuty` (the proposal slot must be a real assignment via `dutyStore.Proposer`, with RANDAO-style tolerance — accept while the slot's epoch is unfetched, since the duty fetch may be in flight). Layered with the earliness/lateness window + committee membership + the runner's expected-root check. + +### T10 — Runner registration & wiring **(needs U0; T5, T6, T8 runners)** +Register the new roles in `SetupRunners` (`operator/validator/controller.go`, `runnersType` + `switch`). **Correction (verified building T5):** the node duty→role map `RunnerRoleForValidatorDuty(duty, isBooleFork)` needs **no** new arm — its Boole branch already returns `duty.RunnerRole()`, which ssv-spec maps for the new BN roles (the same path PTC uses); and per-role queues **auto-create** from the registered `DutyRunners` (`validator.go:~81` ranges `options.DutyRunners`), so no `validator.go` change. **ProposerPreferences: done** (registered with `FeeRecipientProvider`=validatorStore + `GasLimit`; PTC already registered). **Pending:** EnvelopeProposer (T8). + +### T11 — Fork cutover & transition **(needs T3–T8)** +`GLOAS_FORK_EPOCH` is fetched from the BN at runtime (external, ~Q3 2026; lives in `Beacon.Forks[DataVersionGloas]`, gated by `(*Beacon).IsGloas`); the ValidatorRegistration→ProposerPreferences switchover at the boundary; the pre-fork preferences emission window; transition tests (boundary epoch where old + new coexist). **Mirror Boole's transition machinery rather than inventing it:** `InBooleTransitionWindow` / `inBoolePriorWindow` / `inBooleSubsequentWindow` (`networkconfig/network.go`, with `boolePriorWindowEpochs` / `booleSubsequentWindowSlots`) is the direct template for both the Gloas cutover and the pre-fork ProposerPreferences emission window (U4/T5). Develop/test on devnets until a public testnet schedules the fork. +- **VR deprecation: done** (committed). Gloas-gated stop at all three points: `validRoleAtSlot(RoleValidatorRegistration)` rejects Gloas-or-later slots; the VR duty handler skips emission (periodic + event enqueue); the periodic `VRSubmitter` stops submitting. Added `networkconfig.TestNetworkWithGloas(epoch)` test fixture (TestNetwork has no Gloas fork) + 2 tests. The VR runner stays registered but goes idle (handler emits nothing). +- **Pre-fork emission: done** (uncommitted). `Beacon.GloasForkEpoch()` + `Network.InGloasPriorWindow(slot)` (mirrors `inBoolePriorWindow`, `gloasPriorWindowEpochs = MIN_SEED_LOOKAHEAD = 1`); the prefs handler's per-tick logic extracted to `emitForTick`, which in the prior window pre-emits the first Gloas epoch's preferences (`emitForEpoch(epoch+1)`); 3 tests. **So T11 = done** (cutover both directions). Remaining: end-to-end boundary testing belongs with the broader e2e effort. +- **Cleanup (carry here):** `DefaultGasLimit` and the `feeRecipientProvider` interface live in `protocol/v2/ssv/runner/validator_registration.go` but are now also consumed by `proposer_preferences.go` (the runner). Since this fork deprecates the ValidatorRegistration runner, relocate both to a neutral file (e.g. `runner.go`) as part of the cutover so removing VR doesn't orphan them. Compiler-caught, not silent — safe to defer to here. + +### T12 — Testing **(per track + integration + e2e)** +Unit tests per runner/handler/validation arm (against T2 mocks); fork-boundary tests; **e2e on a local Gloas devnet** — the full-impl decision (U2) makes this the real acceptance bar. **e2e vehicle — ssv-mini** (`github.com/ssvlabs/ssv-mini`): the SSV-labs Kurtosis stack already runs Lighthouse + Geth + the SSV layer (4 operators, validators, contracts via Hardhat) at the **Boole** fork. **Prerequisite (a task in the ssv-mini repo):** bump its Ethereum layer from **Fulu → a Glamsterdam/Gloas-capable Lighthouse + Geth** with Glamsterdam fork params (mirror the ethpandaops `glamsterdam-devnets` configs); then run the Gloas SSV implementation e2e against it.

Building on `stage` and rebasing across the Boole merge later is a *rewrite*, not a rebase — every hunk on T4–T10 conflicts against Boole-restructured code, and you'd build to the pre-Boole design (re-creating the `runner_role.go`/`consensus_data.go` switches Boole already has). + +**Path:** +1. **Branch off a `boole-fork` tip now.** You get the correct baseline immediately — `RoleAggregatorCommittee=6`, `ProposerConsensusData`, the node-side switches to extend, `SSVForks{Boole}` + transition-window machinery to mirror. Build it right the first time. +2. **Track `boole-fork` until it lands (~2-3 weeks).** It's ~46 behind stage (Apr 2026), so you're developing on **Apr-stage**; `boole-fork` will be refreshed against stage before/at landing, so merge its updates into the ePBS branch as they appear and **re-run the independent tests after absorbing the refresh** (the Apr→Jun reconciliation can touch your files).

The only still-blocked items are blocked *regardless of Boole*: T8 (U1 design call) and the upstream go-eth2-client rebase / #580 endpoints (external). + +**Accepted cost:** starting now means ePBS eats a rebase across the Boole landing (the 46-commit stage reconciliation + the merge) and a re-validation pass after absorbing `boole-fork`'s refresh. That's the deliberate price of getting independent ePBS testing going in parallel — bounded by the ~2-3 week landing horizon, and the `--onto` mechanics keep the final move mechanical. + +**First incremental rebase — done** (validates the approach — small surface, not a big-bang). `boole-fork` was refreshed (#2899 + #2900); ePBS rebased onto it with two reconciliations: **scheduler.go** — boole-fork's new `dutySlotIsExecutionSlot` lateness guard was *combined* with the PTC cutoff baseline (the guard is true for PTC, so it doesn't replace it); **ptc_attester.go** — boole-fork renamed the runner completion API (`finishDuty`/`ErrRunningDutyFinished` → `markDuty*`/`ErrRunningDutySucceeded`), so abstains now use `markDutyNotRequired`. go.mod/go.sum auto-merged cleanly; #2900 also fixed a pre-existing Electra aggregate-index test.

The only real blocker was Gloas-capable client images, solved by the ethpandaops `glamsterdam-devnet-5` builds (all EL/CL clients tagged). + +Implemented across three PRs (the local Gloas net reuses `local_testnet`'s on-chain identity — same contracts/validators — so no DB-seed duplication; Gloas is beacon-driven, read from the BN's `GLOAS_FORK_EPOCH`, so the SSV node needs no change): +1. **ssv-mini [#34](https://github.com/ssvlabs/ssv-mini/pull/34)** — `params-gloas.yaml` + `make run-gloas`: Fulu at genesis → Gloas at epoch 2, `glamsterdam-devnet-5` EL/CL images, genesis-generator pinned to `6.0.8` (6.1.0's default `5.3.5` predates Gloas), `boole_epoch: 0`. Usable standalone today for direct PTC observation (logs/dora): `SSV_COMMIT=epbs-gloas make prepare && make run-gloas`. +2. **ethereum2-monitor [#504](https://github.com/ssvlabs/ethereum2-monitor/pull/504)** (scoped in #503) — Gloas block decoding (go-eth2-client v0.28.x can't decode Gloas): a reactive raw-JSON fallback in `beacon.FetchBlock` — no SSZ, no shared types. Re-enables E2M attestation validation on a Gloas chain. +3. **aetheria [#123](https://github.com/ssvlabs/aetheria/pull/123)** — a `local_testnet_gloas` network that routes to `params-gloas.yaml`, reusing local_testnet's identity; E2M capture made best-effort. `make run NETWORK=local_testnet_gloas TESTS='(event)'`. + +### Sequencing +- **Done (codeable side):** P1 image + the `networkconfig` stub — both shared by the two tracks. +- **Next (infra, your hands):** devnet-5 sanity check → SSV contract deploy + 4 operators → validators → fill the 3 stub TODOs → run + observe PTC. +- **Track 1** (live devnet) is the path to PTC execution today; **Track 2** (ssv-mini local) is now implemented (above) and is the hermetic/CI path. + +**Track 2 merge/enable order (don't lose the monitor re-enable — it's the one cross-repo coupling):** +1. **ssv-mini #34** — mergeable now; `make run-gloas` works standalone (monitor off; observe ePBS via SSV logs + dora). Its `params-gloas.yaml` keeps `monitor.enabled: false` deliberately, so it's mergeable before E2M ships Gloas support. +2. **ethereum2-monitor #504** — merge; then rebuild the monitor image (ssv-mini `make prepare-monitor`, built from `../ethereum2-monitor`). +3. **ssv-mini follow-up** — once #504 is in the monitor image, flip `monitor.enabled: true` in `params-gloas.yaml`. This turns on E2M attestation validation on the Gloas chain. *(This is the easy-to-forget step — it's intentionally deferred out of #34 so #34 stays mergeable today.)* +4. **aetheria #123** — merge last; `local_testnet_gloas` then runs the full executor `(event)` flow with E2M. Its E2M capture is best-effort, so it also works between steps 1 and 3 — just without E2M validation until the monitor is re-enabled. + +Independent: aetheria #123 and ssv-mini #34 don't depend on #504 to *function* (E2M just stays skipped); #504 + step 3 only add E2M validation. The PTC/proposer/envelope ePBS behavior itself is observable from step 1 via node logs + dora. + +### PR #2855 (MEV timing games) — hold; merge ePBS first +**Decision:** do not merge #2855 for now — merge ePBS first, then reconsider #2855's role. + +Rationale: ePBS removes the *out-of-protocol* apparatus #2855's doc configures (mev-boost/commit-boost relay polling — gone post-Gloas), but **not** the underlying "select the bid as late as the deadline allows" dynamic. Post-Gloas that lever relocates: for a non-self-building proposer it moves *into SSV* (when it calls `GetGloasBeaconBlock`) and/or the BN's own bid selection, while the larger late-MEV lever moves to the builder (or SSV's §6 envelope timing when self-building). So #2855's SSV-side knob (`ProposalSoftDeadline`) likely **carries over with re-derived bounds** for the tighter 25%-of-slot (vs 33%) attestation deadline — a reduced job, not a removed one — which is what to re-evaluate once ePBS lands. + +- `ProposerDelay`: **keep, do not deprecate** — the live pre-Gloas MEV knob and, with #2855 on hold, the only one. Re-tune its role/bounds for ePBS rather than removing it. +- Docs: EXTERNAL_BUILDERS.md ePBS forward-pointer added (#2901); the MEV_CONSIDERATIONS.md full ePBS rewrite is deferred to the mainnet track. + +### ProposerDelay → ePBS split — DONE (#2901) +Fork-gated per-slot (`IsGloasAtSlot`): +- **Pre-ePBS:** `ProposerDelay` + `AllowDangerousProposerDelay` unchanged, but apply **pre-fork only** (today `ProposerDelay` fires under Gloas too — it sits before the `IsGloasAtSlot` branch in the proposer runner, so this is a real carve-out). +- **Post-ePBS:** `ProposerDelay`/`AllowDangerousProposerDelay` have no effect; a new **`ProposerDelayEPBS`** takes over with similar behavior, **hard-capped at 1000ms** (startup-rejected above it — no `AllowDangerous` override, for simplicity), **default 0** (opt-in). Tighter ~25% deadline + smaller/uncertain MEV upside ⇒ no aggressive escape hatch; default-off until devnet-5 measurements justify a value. +- Self-document the flag in #2901 (config-struct comment + `config.example.yaml`); the MEV_CONSIDERATIONS.md prose update lands later in #2855 once its shape is final. +- Proposer budget under Gloas = `ProposerDelayEPBS` + the QBFT round timer (audit ① below). NOTE (corrected): the pre-Gloas `proposalSoftTimeout` does **not** apply under Gloas — the produce path uses `firstClientResult` and bypasses it (audit ④), so there's no proposalSoftTimeout↔delay coupling to tune. + +### Gloas timing audit — full inventory (thirds → quarters) +Every hardcoded slot-relative timeout/deadline classified so none is missed when `IntervalDuration` goes thirds→quarters. Scope: duty-execution + beacon-fetch + QBFT timing. (Out of scope by nature: p2p timeouts and message-validation lateness — those are slot-*count* / fixed-margin based, not interval-fraction, so the quarters change doesn't move them.) + +**Auto-scales via `IntervalDuration` — OK, no change:** aggregation fetch (`beacon/goclient/aggregator.go:95`), sync-contribution delay (`sync_committee_contribution.go:135`), scheduler exec delays (`operator/duties/scheduler.go:362,444`), indices-change deadlines (`proposer.go:121`, `attester.go:131`), 50% aggregator mark (`aggregator_committee.go:236`), `PayloadAttestationCutoff`=3/4 (`networkconfig/beacon.go:66`). + +**Hit-list — needs Gloas adjustment:** +1. **QBFT round timer — DONE (#2901).** `round1HeadStart` now derives from `IntervalDuration` (1× committee, 2× aggregator), so head starts track quarters under Gloas; `RoundTimeout`/`EstimatedRoundAt` (+ the message-validation `estimatedRoundAt`) pass `IntervalDuration(slot)`; pre-Gloas behavior is byte-identical (interval = `slotDuration/3`, verified by unchanged test expectations + a new Gloas case). **`QuickTimeout` kept at 2s** — it's a fixed round-trip budget, not a slot fraction — so the Gloas proposer is effectively round-1-must-succeed; shrinking it to restore the round-2 fallback is deferred to devnet RTT data (documented at the `QuickTimeout` const). (`QuickTimeoutThreshold`=8 / `SlowTimeout`=2min → leave.) +2. **`weightedAttestationData{Soft,Hard}Timeout` — DONE.** Scaled proportionally to the attestation window via a new `scaleToAttestationWindow(base, slot)` helper (integer `base * 3 / intervalsPerSlot`): unchanged pre-Gloas (1/3 window), ×3/4 from Gloas (1/4 window, ~4s→3s). Applied to the hard + soft fetch budgets and their soft/2 (scoring) + soft/4 (block-header) derivatives. Assumes BN response timings are fork-independent (the stated decision); nil-guarded for pre-init. +3. **Attestation refetch — DONE.** `minTimeForRetry`/`refetchDelay`/`refetchTimeout` scaled by the same `scaleToAttestationWindow` helper (the 100ms poll ticker is fork-agnostic granularity → left). + +**Checked — not applicable / corrected:** +4. **`proposalSoftTimeout`** (`options.go:47`, default 1800ms; min 500ms) — *not* a Gloas issue. The Gloas produce path uses `firstClientResult` (`gloas_proposer.go:28`) and bypasses it (pre-Gloas-only). The real Gloas question is a *design* one — should Gloas produce do multi-BN bid comparison / a soft timeout at all? — tied to `ProposerDelayEPBS`; forward-looking, not a constant to lower. +5. **§6 envelope / PTC / proposer-preferences runners — clean.** No hardcoded slot timing; all deadline-driven (deadline injected by the scheduler/executor). + +**Fork-agnostic — leave (verified):** `commonTimeout` 5s / `longTimeout` 60s (general HTTP); `ptcHTTPClient` has no client timeout — ctx-bounded (PTC fetches use `commonTimeout`, bounded by the slot-end duty deadline; Gloas produce/submit bounded by the proposer ctx); `blockPropagationDelay` 300ms (network propagation); scheduler `slotDelay≥100ms` drift threshold (L496/553); `attest.go:430` 100ms poll granularity; `observability.go:148` 1ms log threshold; queue micro-timings (`inboxReadFrequency` 1ms, `retryDelay` 25ms, ttlcache 10min, `SlotDuration/retryDelay` retry count); slotticker (SlotDuration boundary ticker); `DefaultSlotDuration` 12s. + +**Approach:** derive the hit-list fixes from `IntervalDuration`/the Gloas deadline (one fork-scaling source of truth), matching how the §1 deadlines already work.

Re-publishing a signed block/envelope to multiple BNs is safe (they dedupe by root); first-success risked a missed proposal when the first BN accepts but is slow to gossip or partitioned. Produce/GET paths stay on firstClientResult. Envelope duty-assignment check: validateBeaconDuty now requires RoleEnvelopeBuilder messages to carry a real proposer assignment (mirroring proposer-preferences, IsEpochSet-guarded) instead of falling through to a pass. The self-build envelope rides the proposer's slot, so without this a peer could push envelope-role messages for slots where the validator holds no proposal duty. Dependent-root singleflight: the collapsed ProposerDutiesDependentRoot GET runs on a detached context (WithoutCancel + a fresh common-timeout), so a leader caller's cancellation no longer fails concurrent waiters that hold later proposal-slot deadlines. Unconfigured-network guard: SSVConfigByName errors on a zero registry contract address instead of letting a placeholder devnet config silently sync from 0x0 and find no validators.

On the Gloas devnet this surfaced as the proposer missing every block it was assigned. fetchAndProcessDuties now returns (fetched bool, err error); the caller marks the intent fulfilled only when a beacon fetch actually ran. "No eligible validators" returns fetched=false, leaving the intent pending so a later tick retries — the same model the PTC and proposer-preferences handlers already use. Also drop the now-redundant per-fetch bracket log lines, and add a temporary proposer diagnostic (ssvlabs/ssv#2901) that dumps the Validators()/ SelfValidators() view on no-eligible to confirm the root cause on devnet.

Web3Signer derives the domain from `fork_info`, so attestation/sync/aggregation/block partial-sigs sign under the wrong domain → rejected or fail reconstruction (SSV also sends a correct BN-derived `SigningRoot`, so it's a mismatch-reject or wrong-domain sig — either way fail-safe). **Pinned domains exempt:** voluntary-exit (Capella) and validator-registration (genesis) override `fork_info`, so they keep working. **Fix (scoped, no ripple):** resolve the Gloas fork *inside `GetForkInfo`* via the **existing `ForkAtVersion(spec.DataVersionFulu+1)`** interface method — it returns the configured Gloas fork (the real `gloasForkVersion`, populated from the BN spec in `beacon/goclient/spec.go`); gate on `epoch ≥` its fork epoch (= `IsGloas`). **No interface change, no direct `Forks` access.** Do **not** extend `BeaconForkAtEpoch`: its `spec.DataVersion` return feeds ~8 callers (committee/aggregator/goclient submission tags) that deliberately cap at Fulu (its own `TODO(gloas)`). **Module boundary:** the ssvsigner module has its own go.mod and **can't import `networkconfig.DataVersionGloas`**, so it defines the Gloas data version locally as `spec.DataVersionFulu+1` (mirroring the placeholder). `RemoteKeyManager.beaconConfig` is `networkconfig.Beacon` in production (`operator/node.go`); the ssvsigner's own `beaconcfg.Config` (e2e) has the same Fulu cap but only matters if it ever computes signing `fork_info`. **Cross-system (devnet-confirm):** Web3Signer's `compute_domain` is generic over the version bytes, so the correct Gloas `fork_info` should suffice with no Web3Signer Gloas support — the only non-in-repo fact; confirm against a live Web3Signer. - **RS-2 — §4 remote block signing: NOT a simple "add a case" (module boundary + cross-system; DEFERRED).** `handleDomainProposer` → `ConvertBlockToBeaconBlockData` type-switches on the block, but the Gloas block is `protocol/v2/types/gloas.BeaconBlock` (main module) and **the ssvsigner module has its own go.mod, doesn't require the main module, and imports no `gloas`** — so it *cannot* add a `case *gloas.BeaconBlock:`; the block falls through to `default: "obj type is unknown"` (`ssvsigner/web3signer/block_data.go`). *(The signing root is still computed correctly via `ComputeETHSigningRoot(obj, domain)` on the `ssz.HashRoot` interface; only `req.BeaconBlock` — the header BLOCK_V2 needs — can't be built.)* **Fix (design decision, spans both modules):** the node-side proposer path passes the **block header** (`phase0.BeaconBlockHeader`, a go-eth2-client type nameable in ssvsigner; `HTR(header) == HTR(block)`, so the signing root is unchanged) instead of the full Gloas block; the converter gains a `case *phase0.BeaconBlockHeader:`; `handleDomainProposer` supplies the Gloas version. **Cross-system:** whether Web3Signer accepts a Gloas-version BLOCK_V2 is unverified (may gate on Web3Signer Gloas support). Bigger than RS-1 and cross-system-gated → **deferred**; RS-1 already unblocks every remote duty except the §4 block. - **RS-3 — §3/§5/§6 have no Web3Signer request type (upstream-blocked; already in §2b).** The PTC/preferences/envelope arms return descriptive errors + `TODO(gloas)`; `SignRequest` has no matching field.

Glamsterdam (EIP-8282) adds builder_deposits and builder_exits, so a Gloas CL encodes five lists. The three-list type marshaled the §4 block two offsets (8 bytes) short, and lighthouse v8.2.0 (glamsterdam-devnet-6) rejected POST /eth/v2/beacon/blocks as invalid SSZ (InvalidLengthPrefix{len:0, expected:4}). Empty request lists let the three-list decoder read a real Gloas block without erroring, so the drift only surfaced on submit, not on produce. Add a node-side gloas.ExecutionRequests (the Electra three plus BuilderDepositRequest and BuilderExitRequest, list bounds 256/16) and use it for both the §4 ParentExecutionRequests and the §6 envelope, keeping the two identical so the blinded and full envelopes still hash equal. Verified on local_testnet_gloas: §4 block publication passes end-to-end (blocks land canonically) and a real v8.2.0 on-chain block round-trips byte-for-byte through the node's SignedBeaconBlock codec — guarded by beacon_block_wire_test.go against future wire drift. Also correct a stale assertion in gloas_proposer_test.go: the block-produce path pads graffiti to 32 bytes, but the test still expected the short unpadded form (a pre-existing failure on the branch). --- beacon/goclient/gloas_envelope_test.go | 3 +- beacon/goclient/gloas_proposer_test.go | 7 +- protocol/v2/ssv/runner/envelope_test.go | 5 +- protocol/v2/ssv/value_check_test.go | 3 +- protocol/v2/types/gloas/beacon_block.go | 7 +- .../v2/types/gloas/beacon_block_encoding.go | 6 +- protocol/v2/types/gloas/beacon_block_test.go | 3 +- .../v2/types/gloas/beacon_block_wire_test.go | 30 ++ .../types/gloas/execution_payload_envelope.go | 11 +- .../execution_payload_envelope_encoding.go | 11 +- .../gloas/execution_payload_envelope_test.go | 9 +- protocol/v2/types/gloas/execution_requests.go | 40 ++ .../gloas/execution_requests_encoding.go | 497 ++++++++++++++++++ .../gloas/testdata/devnet6_gloas_block.ssz | Bin 0 -> 1367 bytes protocol/v2/types/gloas/testing.go | 3 +- 15 files changed, 596 insertions(+), 39 deletions(-) create mode 100644 protocol/v2/types/gloas/beacon_block_wire_test.go create mode 100644 protocol/v2/types/gloas/execution_requests.go create mode 100644 protocol/v2/types/gloas/execution_requests_encoding.go create mode 100644 protocol/v2/types/gloas/testdata/devnet6_gloas_block.ssz diff --git a/beacon/goclient/gloas_envelope_test.go b/beacon/goclient/gloas_envelope_test.go index f2ee82e3a2..9c99e8bc6e 100644 --- a/beacon/goclient/gloas_envelope_test.go +++ b/beacon/goclient/gloas_envelope_test.go @@ -8,7 +8,6 @@ import ( "strings" "testing" - "github.com/attestantio/go-eth2-client/spec/electra" "github.com/attestantio/go-eth2-client/spec/phase0" "github.com/stretchr/testify/require" @@ -22,7 +21,7 @@ var _ beacon.GloasEnvelopeCalls = (*GoClient)(nil) func minimalExecutionPayloadEnvelope() *gloas.ExecutionPayloadEnvelope { return &gloas.ExecutionPayloadEnvelope{ Payload: &gloas.ExecutionPayload{}, - ExecutionRequests: &electra.ExecutionRequests{}, + ExecutionRequests: &gloas.ExecutionRequests{}, BuilderIndex: gloas.BuilderIndexSelfBuild, } } diff --git a/beacon/goclient/gloas_proposer_test.go b/beacon/goclient/gloas_proposer_test.go index 226e97c2ad..82d2e0c399 100644 --- a/beacon/goclient/gloas_proposer_test.go +++ b/beacon/goclient/gloas_proposer_test.go @@ -5,10 +5,10 @@ import ( "io" "net/http" "net/http/httptest" + "strings" "testing" "github.com/attestantio/go-eth2-client/spec/altair" - "github.com/attestantio/go-eth2-client/spec/electra" "github.com/attestantio/go-eth2-client/spec/phase0" bitfield "github.com/prysmaticlabs/go-bitfield" "github.com/stretchr/testify/require" @@ -27,7 +27,7 @@ func minimalGloasBlock() *gloas.BeaconBlock { ETH1Data: &phase0.ETH1Data{BlockHash: make([]byte, 32)}, SyncAggregate: &altair.SyncAggregate{SyncCommitteeBits: bitfield.NewBitvector512()}, SignedExecutionPayloadBid: &gloas.SignedExecutionPayloadBid{Message: &gloas.ExecutionPayloadBid{BuilderIndex: gloas.BuilderIndexSelfBuild}}, - ParentExecutionRequests: &electra.ExecutionRequests{}, + ParentExecutionRequests: &gloas.ExecutionRequests{}, }, } } @@ -53,7 +53,8 @@ func TestRequestGloasBeaconBlock(t *testing.T) { require.Equal(t, "/eth/v4/validator/blocks/7", gotPath) require.Equal(t, "false", gotIncludePayload) // bare block;

So **T7/T10 extend those, they don't author wrappers.** **`boole-fork` has not yet landed on stage** (stage is still `ssv-spec v1.2.2` / `SSVForks struct{}`; `boole-fork` is ~46 commits behind stage, tip Apr 2026) — but it's **expected to merge within ~2-3 weeks (≈ mid-July 2026), treated as ground truth** (see §2b). The build baseline is **`boole-fork`** (verify anchors against it). **Decision: ePBS starts now off `boole-fork`** — it must begin immediately for independent development + testing (against T2 mocks/devnet, which doesn't gate on Boole landing), so it can't wait for the merge; it rebases onto stage when Boole lands (~2-3 weeks) — see §6.

The SIP remains the canonical wire source.

(Note: `builder_index` is *not* the validator index in self-build; the non-self-build branch reads a separate `state.builders[...]` registry.) - -**Node-side facts (resolved during research):** -- **No SSV `DomainType` bump needed for Gloas** (conclusion holds; pre-Boole basis corrected). Gloas is a **beacon** fork — gate it by beacon epoch via `Beacon.BeaconForkAtEpoch` (Boole's rename of `ForkAtEpoch`; see U5). The pre-Boole basis ("`SSVForks` is an empty struct") is now **false**: Boole made `SSVForks{ Boole phase0.Epoch }` and added a `DomainType`/`NextDomainType` rotation (`networkconfig/ssv.go`). But those are **SSV-fork** (Boole) concerns, distinct from beacon forks, and the Gloas signing domains (`0x0B/0C/0D`) are beacon-side — so the SSV `DomainType` is untouched. Open at T1: whether Gloas also wants an `SSVForks` entry now that the machinery exists, or stays purely beacon-epoch-gated (default: beacon-epoch — it's beacon-driven). -- **Slashing protection needs no change.** Double-vote/surround detection compares **only `Source.Epoch`/`Target.Epoch`** — eth2-key-manager's `NormalProtection.IsSlashableAttestation` (reached via `ssvsigner/ekm/slashing_protector.go`) never inspects `index`, and by design doesn't even store signing roots. The full `AttestationData` is SSZ-persisted (`ssvsigner/ekm/signer_storage.go`), but only the source/target epochs are ever read for the slashable check — so the Gloas `index` semantics change is irrelevant to slashing, not because `index` is now part of the compared data but because it never was. The only index-aware work is in the value-check construction (T4). -- **A second concurrent QBFT instance for the same (validator, slot) is cleanly supported.** The two roles stay separate: message-validation consensus state and validation locks are keyed by `MessageID` (which includes `RunnerRole`), and runner queues by `RunnerRole` — so EnvelopeProposer (§6 QBFT variant) won't collide with the proposer's block QBFT. **Caveat:** this isolation holds on the per-validator runner path (`protocol/v2/ssv/validator/validator.go`, role-keyed `Queues`); the Committee path keys queues by **slot** (`committee.go`), not role. The three new roles must therefore be wired as per-validator runners, never onto the committee path (see T10). -- **The shared Gloas vote is inert for sync-committee duties.** The committee runner's sync path reads only `BeaconVote.BlockRoot` (`committee.go` sync-message construction); adding `AttestationDataIndex` to the vote doesn't touch it. -- **`api.VersionedProposal.Blinded`** is the local-vs-builder signal (already logged via `BeaconBlockIsBlindedAttribute`) — the basis for the U6 local-build metric. - -**Dependency landscape (resolved):** -- **go-eth2-client has no Gloas types** — neither the SSV fork (`v0.6.31-…`, based on upstream v0.27.0) nor upstream master (`v0.28.1`). No `DataVersionGloas`, no `spec/gloas` package. → the fork must be patched (U2). -- **ssv-spec has no Gloas work** (no branch/PR). The **AggregatorCommittee consolidation is now the baseline** — Boole bumps the node to `ssv-spec v1.2.3-pseudo` (`RoleAggregatorCommittee=6`; deprecated `RoleAggregator=1`/`RoleSyncCommitteeContribution=3` gaps), so the pre-Boole "`v1.2.2` contiguous/pre-consolidation" framing no longer applies. → U0. - ---- - -## 1.

Line numbers are approximate (`~`) and may drift. -- Each new runner role touches five seams: **(a)** type/enum, **(b)** runner impl, **(c)** `SetupRunners` registration, **(d)** duty handler/trigger, **(e)** message validation. -- **Observability is logs-first (see §8).** Every test/verification claim in this plan must be expressed as a **greppable DEBUG log-line** — so all planned testing is automatable (grep the line, assert it).

Resolved investigations (findings + decisions) - -### U0 — How the new protocol types enter the node **(decided — incl. the ssv-spec posture)** -**Findings:** -- The new wire constants (roles, partial-sig types, domains, `GloasBeaconVote`, `EnvelopeConsensusData`, `BlindedExecutionPayloadEnvelope`) **do not exist in canonical ssv-spec** — there's no Gloas branch/PR. SSV must author them regardless of bump-vs-copy. -- ssv-spec's AggregatorCommittee consolidation is now **the baseline** — it lands in stage via the **Boole** fork (`ssv-spec v1.2.3-pseudo`). ePBS builds **on top of** the consolidated roles; the old "decouple an unreleased refactor" framing is obsolete. -- Wire values are protocol-canonical and must match Anchor; the **SIP (not an ssv-spec PR) is the canonical wire source**. - -**Decision/recommendation:** -- **The consolidation is the Boole baseline, not an ePBS prerequisite** — ePBS builds on it (shipped via `boole-fork`); it never owns or bumps it. -- **Add the Gloas types in-tree now** (e.g. a `gloastypes` package), using the SIP's canonical values: `RunnerRole` PTC=7/Prefs=8/Envelope=9; `BeaconRole` 7/8/9; `PartialSigMsgType` `PTCAttesterPartialSig`=7, `ProposerPreferencesPartialSig`=8 (+ `EnvelopePartialSig`=9 only if U1 picks no-QBFT); domains `0x0B/0x0C/0x0D`. These slot cleanly above the now-baseline consolidated max (`RoleAggregatorCommittee=6`), verified against post-Boole `ssv-spec v1.2.3-pseudo`. (Wire values verified against SIP #94: roles 7/8/9, partial-sigs 7/8, domains `DomainBeaconBuilder=0x0B`/`DomainPTCAttester=0x0C`/`DomainProposerPreferences=0x0D`; the SIP reserves RunnerRole 1/3 for pre-consolidation back-compat decoding.) -- **Extend Boole's existing node-side switches — don't author new wrappers.** Boole already moved both switches node-side (for its own consolidation back-compat): `protocol/v2/types/consensus_data.go` version-switches extraction over `spectypes.ProposerConsensusData` (the `getBlockData` seam), and `protocol/v2/types/runner_role.go`'s `RunnerRoleForValidatorDuty(duty, isBooleFork)` is the fork-aware duty→role map (replacing `spectypes.MapDutyToRunnerRole` node-side). So T7 adds a `DataVersionGloas` arm to `consensus_data.go`, and T10 adds the three new roles + an `isGloas` branch to `RunnerRoleForValidatorDuty` (mirroring its existing `isBooleFork` shape). The "wrappers" are extension points already in-tree — and already the migration seams. **Parameterizes T7, T10.** -- **Lock the Anchor wire constants early, not at end-of-execution.** They're already in the SIP (roles 7/8/9, partial-sigs 7/8, domains `0x0B/0C/0D`) and isolated — so confirming them with Anchor is *cheap now* and *expensive to discover wrong at interop*. Isolation makes them cheap to lock early, not a reason to defer. Proceed with the SIP-canonical values and get Anchor's explicit ack up front (against the SIP — the canonical wire source, no ssv-spec PR) rather than deferring to the end (see §2b). - -**ssv-spec posture (decided): migrate off ssv-spec imports entirely** (end-state). ePBS runs in the pragmatic fallback: **define the new types we need node-side; never modify, bump, or PR ssv-spec.** Guiding principle for every track — *do not deepen ssv-spec coupling*: new types are node-side; existing ssv-spec types are extended (node-side constants of the existing type) or wrapped, never edited; any node-side type that mirrors an ssv-spec one stays **SSZ/wire-identical** through the hybrid phase. The consolidation shipped via Boole's ssv-spec bump (`v1.2.3`) and is the baseline; ePBS neither bumps nor owns it. **Parameterizes T1, T7, T10, and all role work.** - -**Relationship to the full migration:** owning *all* duty-related types node-side (`ValidatorConsensusData`/`BeaconVote`/duty/role/value-check, `MessageID`, the QBFT types, …) is a **separate, larger initiative** — out of scope here. ePBS is its **first down-payment**: the Gloas types land node-side, and the wrappers (T7/T10) are the seams the migration will later cut. That migration's main cost is **spectest decoupling** (the node runs ssv-spec test vectors) — but ePBS doesn't pay it: Gloas has no ssv-spec vectors, so the new node-side types don't disturb existing spectest compatibility. Forward-compat: the Gloas role/partial-sig constants are values of the *existing* `spectypes` base types for now, and move wholesale when those base types are reimplemented node-side. Note: nothing in ePBS *forces* an ssv-spec edit — QBFT is value-agnostic (a new instance over `BlindedExecutionPayloadEnvelope` needs only a node-side value-check), and `MessageID` is reused read-only with node-side role values. **Steady-state caveat (largely moot post-Boole):** the duty→role / consensus-data switches T7/T10 extend are **already in-tree as Boole's** (`runner_role.go`/`consensus_data.go`), serving Boole's own consolidation back-compat — so they're load-bearing regardless of whether the ssv-spec migration ever runs. Only `gloastypes` is genuinely ePBS-introduced, and it's a clean node package fine to live with permanently. - -### U1 — §6 envelope distribution: QBFT vs no-QBFT(sign-all) **(RESOLVED — QBFT; SIP #94 maintainer call, 2026-06-23)** -**Decision: QBFT** — keep the SIP's prescribed shape (a second QBFT round over the blinded envelope; **no** new `PartialSigMsgType` — post-consensus reuses `PostConsensusPartialSig`, role discriminates routing). GalRogozinski on the §6 thread ([r3460315536](https://github.com/ssvlabs/SIPs/pull/94#discussion_r3460315536)): *"QBFT is the correct call for now. It handles the faulty leader edge case. The way forward is for later SIPs to reduce the QBFT timeout. Eventually we need a more suitable consensus algo."* This **overrules** the earlier node-side recommendation (no-QBFT sign-all). What carried it (shane-moore's surface argument, [r3364710775](https://github.com/ssvlabs/SIPs/pull/94#discussion_r3364710775)): the no-QBFT path's real cost is a **new top-level network message class** — a dissemination carrier for the `BlindedExecutionPayloadEnvelope` plus a new `EnvelopePartialSig` kind — touching the message-validation dispatch, a new validated-message variant, receiver routing, and byte-compat across every client (go-ssv, Anchor, future). QBFT reuses existing consensus machinery with **no new message class** and the default round-robin leader; its degeneracy (a round-changed envelope leader ≠ block proposer) is mild given the ~6s budget from the 25% block deadline to the 75% payload-due cutoff. The latency/Byzantine edge for no-QBFT was judged not to outweigh that surface for a path expected to be rare (local-build ~0.1–2%). **Contained to T8 (ships last).** T8 builds the QBFT variant only; the no-QBFT design is retired (kept for history). - -### U2 — go-eth2-client Gloas support + beacon API maturity **(decided)** -**Findings:** -- Gloas is absent from both the SSV fork and upstream — **there is nothing to bump to**. -- produceBlockV4 confirmed: response is `anyOf [Gloas.BeaconBlock, Gloas.BlockContents]` (per #580 head — `anyOf`, not `oneOf`; no blinded-block variant post-Gloas), discriminated by the `Eth-Execution-Payload-Included` header (+ `Eth-Consensus-Version: gloas`); SSZ or JSON. Envelope POST (`publishExecutionPayloadEnvelope`) accepts `SignedExecutionPayloadEnvelopeContents` (stateless) **or** bare `SignedExecutionPayloadEnvelope` (stateful); envelope GET returns `Gloas.ExecutionPayloadEnvelope`. -- **Endpoint maturity tiers:** - - **Merged/tagged** (lower risk): PTC duties, `payload_attestation_data`, `payload_attestations` pool — in `beacon-APIs@v5.0.0-alpha.2` and master. - - **Unmerged** (pin to #580, expect churn): produceBlockV4, envelope POST/GET, `types/gloas/{block_contents,execution_payload_envelope}`. - - **Nonexistent** (fully abstract, no real BN to test against): validator-facing `SignedProposerPreferences` publication. - -**Decision (revised — full node-side implementation; supersedes the earlier mock-only stance):** build the Gloas beacon surface node-side **now** — full-fidelity SSZ/JSON types (BeaconBlock/BlockContents, ExecutionPayloadEnvelope + Contents, PayloadAttestation/Data/Message + PTCDuty, ProposerPreferences/Signed) **and** hand-rolled HTTP endpoint clients — not abstract-and-mock-only. Rationale: a multi-client Glamsterdam/Gloas devnet is **live** (since ~May 2026), so a *real* implementation can be e2e-tested against a local devnet (see T12 / ssv-mini); mock-only can't be. Mocks are kept, but only for unit tests. The go-eth2-client rebase is now a **later dedup** — swap our node-side types/clients for upstream's `spec/gloas` when it ships — **not** a prerequisite or a gate. Types/endpoints are `#580`-pinned and will churn → watch + iterate. (`SignedProposerPreferences` is the lone exception: no endpoint exists in any client, so it stays mock-only — see §2b.) **Parameterizes T2.** - -### U3 — `BeaconNode` interface diff + mocks **(decided)** -Add to `protocol/v2/blockchain/beacon/client.go` (mocks regen via `//go:generate mockgen` at `client.go:~15`): -- `PTCCalls`: `PTCDuties(epoch)`, `PayloadAttestationData(slot)`, `SubmitPayloadAttestations(...)` — merged endpoints. -- `ProposerPreferencesCalls`: `SubmitProposerPreferences(...)` — **no real endpoint yet; mock only**. Supersedes `ValidatorRegistrationCalls` post-fork. -- `ExecutionPayloadEnvelopeCalls`: `GetExecutionPayloadEnvelope(slot, beaconBlockRoot)`, `SubmitExecutionPayloadEnvelope(contents | bare)` — #580. -- produceBlockV4 path on `ProposerCalls.GetBeaconBlock` (version + `Eth-Execution-Payload-Included`-aware). **Parameterizes T2.** - -### U4 — Message-validation model + ProposerPreferences carried-slot **(decided; impl in T9)** -**Findings/decisions:** -- Per-role allowances (`partialSignatureTypeMatchesRole`, `validRole`): PTC + ProposerPreferences are **partial-sig only** (reject consensus messages, like ValidatorRegistration); EnvelopeProposer is **QBFT + post-consensus**. -- **Carried slot (corrected — supersedes the earlier emission-slot sketch):** the base runner ties **three** checks to a single `DutySlot` — `validatePartialSigMsg` (receiver requires `msg.Slot == DutySlot`), `verifyExpectedRoot` (signing-domain epoch from `DutySlot`), and network `messageEarliness`. The wire signature is under `epoch(proposal_slot)`, so `DutySlot = proposal_slot` is **forced**, hence `msg.Slot = proposal_slot` (an emission-slot override would make every receiver drop the message as "slot already passed"). The future `proposal_slot` is instead permitted by a **bounded role-specific earliness allowance** in `messageEarliness` (T9) — not by runner slot-trickery. -- **Pre-fork acceptance:** message validation must accept `RoleProposerPreferences` for `~MIN_SEED_LOOKAHEAD` epoch(s) before `GLOAS_FORK_EPOCH` (fork-aware allow). This is net-new logic — there is **no existing ValidatorRegistration fork-cutoff in message validation to mirror**; both this pre-fork accept and the VR post-fork reject (T5) are new and must be built symmetrically. The gate to design around is `messageEarliness` (role-agnostic, no per-role exemption), which would otherwise reject a future-slot message. -- `dutyLimit` (`common_checks.go:~117`, whose `default` returns `(0, false)` — an *exists* flag the caller uses to skip the limit, not a numeric no-limit) and `messageLateness` (no `default` → unlisted role treated late just past slot-start) both need explicit arms for the three roles (`dutyLimit` arms returning `(limit, true)`). Note `validRole`/`partialSignatureTypeMatchesRole` **already** have arms for the non-QBFT roles (ValidatorRegistration/VoluntaryExit) — a clean template to copy; only `maxRound` (default→error) and `dutyLimit` (default→`(0,false)`) truly lack arms. -**Parameterizes T5, T6, T9.** - -### U5 — Fork-gating + slashing **(decided)** -**Findings/decisions:** -- **Gating:** beacon fork epochs are fetched at runtime from the BN's `/eth/v1/config/spec` (not node config). Wire Gloas by: adding `DataVersionGloas` (via the U2 fork patch), filling the `GLOAS_FORK_EPOCH` TODO in `beacon/goclient/spec.go` (**already present on stage at `spec.go:255`**), adding Gloas to the beacon fork-epoch method, and a node `IsGloas(slot/epoch)` helper. No per-network config-file changes. **Boole-baseline note (corrected):** `spec.go`/`networkconfig/beacon.go` are **not** rewritten by Boole — small diffs only (the GLOAS TODO + fork list pre-exist on stage, so these seams are *more* stable than feared). The one relevant change is the beacon fork method rename `ForkAtEpoch` → `BeaconForkAtEpoch` (`beacon.go:141` on `boole-fork`), done to disambiguate from Boole's new SSV-fork `BooleForkAtEpoch`. Model `IsGloas` on the **beacon** method (`BeaconForkAtEpoch`), **not** the SSV-fork `BooleForkAtEpoch` — Gloas is beacon-driven (see §0). -- **`BeaconVote` ↔ `GloasBeaconVote`** selected by the duty slot's fork; SSZ length differs (112B vs 120B) so cross-fork decode fails cleanly. -- **Slashing: no change** (see §0). **Parameterizes T1, T4.** - -### U6 — Local-build / reconstruction telemetry **(decided)** -Local-build rate: counter split on `api.VersionedProposal.Blinded` (`blinded=false` ≈ local; a **pre-Gloas proxy** — the signal changes post-fork). PTC reconstruction-miss and ProposerPreferences reconstruction-failure: new counters in those runners. **Parameterizes T13** (and informs T8 priority). **Logs-first (§8): these counters are nice-to-have viz only; the primary, automatable validation is the matching greppable DEBUG log (§8 G2 build-source, G3 duty-outcome, and the reconstruction-miss logs) — never the metric alone.** - -### Newly confirmed (folded into tracks) -- Sync-committee path inert to the new vote field → noted in T4. -- `GLOAS_FORK_EPOCH` schedule is external (Glamsterdam ~Q3 2026; devnets now) → T11 / §2b. - ---- - -## 2b.

Implementation tracks (dependency-ordered) - -### T1 — Types + fork-gating scaffolding **(needs U0, U5)** -Per U0: in-tree `gloastypes` package with the SIP-canonical enums/domains/structs (`GloasBeaconVote` (+SSZ, 120B), `EnvelopeConsensusData`, `BlindedExecutionPayloadEnvelope`, roles/partial-sig/domains). Add the `IsGloas` helper and the `ForkAtEpoch` Gloas entry (`networkconfig/beacon.go`). `DataVersionGloas` comes from the T2 fork patch. **Placement (migration-aligned):** land `gloastypes` as a subpackage of the eventual bridge home `protocol/v2/types` (e.g. `protocol/v2/types/gloas`), not a standalone top-level package — so the ssv-spec migration absorbs it into one node-type root without a relocation, and its M1 codemod sweeps it like any other file (migration plan §1). On `boole-fork`, `protocol/v2/types` already hosts node-side `runner_role.go`/`consensus_data.go`/`partial_sig_message.go`, so `protocol/v2/types/gloas` sits beside real protocol-type siblings (placement A confirmed). Model `IsGloas` on the **beacon** fork method (`BeaconForkAtEpoch`), not the SSV-fork `BooleForkAtEpoch` (per U5/§0); `SSVForks` is no longer empty (it has `Boole`) — decide per §0 whether Gloas needs its own entry. - -### T2 — BeaconNode abstraction + full node-side Gloas types & endpoint clients **(needs U2, U3)** -Per U2 (revised — full impl): add the U3 interface methods to `client.go`; define **full-fidelity Gloas types node-side** (in the `gloas` package — SSZ + JSON per `consensus-specs@6ebb2216c` + beacon-APIs#580) and implement the `beacon/goclient/` **endpoint clients (real HTTP)** — not placeholders. Regenerate mocks for unit tests. Tag each method by maturity tier (merged / #580 / endpoint-missing) so the churn surface is explicit. **Order:** PTC call-set first (merged endpoints → live-devnet-testable soonest), then ProposerPreferences (mock-only — no endpoint), then envelope + produceBlockV4 (#580, watch). The go-eth2-client rebase later swaps our node-side types/clients for upstream's `spec/gloas` (a dedup), not a gate. *(`DataVersionGloas` placeholder + `IsGloas` and the `GLOAS_FORK_EPOCH` wiring already landed.)* - -### T3 — §1 slot timing **— done** (uncommitted) -The key realization: ePBS retimes duties from **thirds to quarters**, and every deadline is `N × IntervalDuration` with **N preserved across the fork** (attestation/sync 1×, aggregate/contribution 2×, PTC 3×); the Gloas bps (2500/5000/7500) are exactly 1/4, 2/4, 3/4. So the whole change is one fork-gate: `(*Beacon).IntervalDuration()` → `IntervalDuration(slot)`, returning `SlotDuration/3` pre-Gloas and `SlotDuration/4` from Gloas on. Every `N × IntervalDuration` caller then lands on the right quarter automatically — scheduler attestation timer (`SlotTicker`) + head-event acceleration check, attester/proposer indices-change deadline, the aggregator-committee runner, and `goclient` aggregator + sync-contribution. **Pre-Gloas is byte-identical** (`TestNetwork` has no Gloas). The misleadingly-named `waitOneThird*`/`waitTwoThirds*` helpers were renamed `waitOneInterval*`/`waitTwoIntervals*` with fork-aware comments/logs. PTC's 75% (`PayloadAttestationCutoff` = 3/4) was already correct — untouched. Unit test `TestBeacon_IntervalDuration` (thirds before the fork, quarters from it on). - -**QBFT round-1 head-start — deliberately not retimed (2026-06-27).** `roundtimer/timer.go`'s `round1HeadStart` (`slotDuration/3` committee, `*2/3` aggregator/sync-contribution — the pre-round-1 wait for the block/attestations to arrive) is the one timing constant *not* routed through `IntervalDuration`, so it stayed at thirds post-Gloas. It is QBFT round-change *liveness* timing, not one of the SIP §1 duty deadlines (all retimed above), so retiming it is out of §1 scope; the post-Gloas misalignment (head-start 1/3 vs the now-1/4 attestation deadline) only loosens leader-rotation timing on the slow path, with no correctness impact. **Decision: leave as-is** — revisit only if consensus timing proves problematic under the tighter ePBS schedule on devnet. (Surfaced by a §1 review.) - -### T4 — §2 attestation / `GloasBeaconVote` **(needs T1, T2, U5) — scoped against Anchor (2026-06)** -**The type already exists** (T1 built `protocol/v2/types/gloas/beacon_vote.go` — `GloasBeaconVote{BlockRoot, Source, Target, AttestationDataIndex}`, 120B SSZ, field-order- and wire-identical to Anchor's `GloasBeaconVote`), referenced nowhere outside its package. So **T4 is pure wiring**, not new types. - -**Anchor's `GloasBeaconVoteValidator` = the pre-Gloas validator + exactly two rules:** (1) range-check `attestation_data_index ∈ {0,1}` (reject ≥2); (2) reconstruct the slashing-check `AttestationData` with the single QBFT-decided index. Everything else (far-future target, source) }` and passes it to the proposer's `StartEnvelopeDuty`. `c.ExecuteDuty` enqueues (async) + routes by pubkey, and `RunnerRoleForValidatorDuty` → `duty.RunnerRole()` → `RoleEnvelopeBuilder` on Gloas (post-Boole) slots, so no role-map change was needed. - - **⑥ message validation — DONE** (committed): the role-9 arm across the validation rules — `validRoleAtSlot` (Gloas-only), `maxRound`=2 + the round-spread skip + `messageLateness` (all like the proposer — QBFT, instance-relative timing), `partialSignatureTypeMatchesRole` (post-consensus only, no pre-consensus), `dutyLimit`=SlotsPerEpoch (≤1 self-build envelope/slot). `committeeRole`/`monotonicSlotRole`/`validateBeaconDuty`/`storedSlotCount` unchanged — not a committee role, not beacon-scheduled, has consensus. Per §0 no infra change (state is `MessageID`-keyed, incl. `RunnerRole`). 5 unit tests. - - **Heavy payload — DONE** (committed): the full Gloas `ExecutionPayload` (Deneb's + `block_access_list` [EIP-7928 — an opaque `ByteList`, *not* the feared nested SSZ: the EL RLP-encodes it, the CL only stores+hashes] + `slot_number` [EIP-7843]; `base_fee_per_gas` as `[32]byte` SSZ uint256), the full `ExecutionPayloadEnvelope`/`SignedExecutionPayloadEnvelope` + a `Blinded()` transform, and goclient `Get`/`SubmitExecutionPayloadEnvelope` (best-effort #580 paths, octet-stream SSZ like §4). The runner's `produceBlindedEnvelope`/`submitEnvelope` are filled (fetch→cache→blind / content-match→holder publishes). **e2e QBFT test — done** (committed): `runner/envelope_e2e_test.go` adapts the proposer's heavyweight harness, covering the post-consensus publish both via direct `submitEnvelope` (builder publishes / competing-envelope operator skips) and a full `ProcessPostConsensus` (share-signed partial-sig quorum under `DOMAIN_BEACON_BUILDER` → reconstruct → publish). **HTR-parity — done** (committed): the `ExecutionPayload` field order, `BlockAccessList` bound (`ByteList[2**30]`), and `slot_number` placement were verified field-for-field against the canonical container (consensus-specs `specs/gloas/beacon-chain.md` @ `6ebb2216c`); `TestExecutionPayloadLayoutMatchesSpec` pins the HTR as a drift guard. **Deferred (devnet-gated):** the `…Contents` blob-carrying publish body — it carries `envelope + blobs + kzg_proofs`, but there's no blob source (T7 defers the §4 `BlockContents`; the proposer caches only the bare block `cachedGloasBlockSSZ`), the #580 publish endpoint accepts *either* the bare envelope (stateful — what SSV does, working) *or* the Contents (stateless), and SSV self-build is naturally stateful (its own BN built + holds the §4 payload). So the Contents form is needed only if a devnet BN runs payload-stateless — revisit then (it also un-defers T7's blob plumbing). **TODO** — a *computational* HTR cross-check against published canonical Gloas SSZ spec vectors once the fork ships (none exist for the unreleased fork yet, so today's check is against the spec *source* + a drift guard, not vectors). -- **Recommendation when resuming:** build ④ as the first focused step (consensus-critical — don't rush it at a session tail), then ⑤/⑥, then the heavy payload last (devnet-validated). - -### T9 — Message validation for new roles **(needs U4; pairs with T5/T6/T8)** -Implement the U4 rule arms: `validRole`, `partialSignatureTypeMatchesRole`, `dutyLimit`, `messageEarliness`/`messageLateness`, `maxRound`. Dual-instance needs **no infra change** (state is `MessageID`-keyed, per §0) — just add the role arms. - -**ProposerPreferences: done** (uncommitted). Mechanical arms mirror PTC (`validRoleAtSlot`=`isInGloas`, `partialSignatureTypeMatchesRole`, `validPartialSigMsgType`, pre-consensus limit, `seen_msg_types`, no-consensus reject). Plus the **multi-future-slot reconciliation** the role forced — its signer holds the whole lookahead at once, which the per-signer state machine (built for monotonic one-slot-at-a-time) didn't fit: (1) `messageEarliness` allowance = the lookahead span (`proposerPreferencesEarlyEpochs`=2 epochs); (2) **exempt from the monotonic `ErrSlotAlreadyAdvanced` check** (`monotonicSlotRole`) — else a higher proposal slot poisons lower ones (devnet-frequent); (3) **`messageLateness` past bound** (replaces the dropped monotonic replay protection); (4) **per-signer ring sized to the lookahead** (`storedSlotCount(role)`) so concurrent lookahead slots don't collide and per-slot dedup stays exact. 7 unit tests. -**Spam hardening: done** (uncommitted). Per-epoch `dutyLimit` arm (`SlotsPerEpoch`) + a duty-assignment check in `validateBeaconDuty` (the proposal slot must be a real assignment via `dutyStore.Proposer`, with RANDAO-style tolerance — accept while the slot's epoch is unfetched, since the duty fetch may be in flight). Layered with the earliness/lateness window + committee membership + the runner's expected-root check. - -### T10 — Runner registration & wiring **(needs U0; T5, T6, T8 runners)** -Register the new roles in `SetupRunners` (`operator/validator/controller.go`, `runnersType` + `switch`). **Correction (verified building T5):** the node duty→role map `RunnerRoleForValidatorDuty(duty, isBooleFork)` needs **no** new arm — its Boole branch already returns `duty.RunnerRole()`, which ssv-spec maps for the new BN roles (the same path PTC uses); and per-role queues **auto-create** from the registered `DutyRunners` (`validator.go:~81` ranges `options.DutyRunners`), so no `validator.go` change. **ProposerPreferences: done** (registered with `FeeRecipientProvider`=validatorStore + `GasLimit`; PTC already registered). **Pending:** EnvelopeProposer (T8). - -### T11 — Fork cutover & transition **(needs T3–T8)** -`GLOAS_FORK_EPOCH` is fetched from the BN at runtime (external, ~Q3 2026; lives in `Beacon.Forks[DataVersionGloas]`, gated by `(*Beacon).IsGloas`); the ValidatorRegistration→ProposerPreferences switchover at the boundary; the pre-fork preferences emission window; transition tests (boundary epoch where old + new coexist). **Mirror Boole's transition machinery rather than inventing it:** `InBooleTransitionWindow` / `inBoolePriorWindow` / `inBooleSubsequentWindow` (`networkconfig/network.go`, with `boolePriorWindowEpochs` / `booleSubsequentWindowSlots`) is the direct template for both the Gloas cutover and the pre-fork ProposerPreferences emission window (U4/T5). Develop/test on devnets until a public testnet schedules the fork. -- **VR deprecation: done** (committed). Gloas-gated stop at all three points: `validRoleAtSlot(RoleValidatorRegistration)` rejects Gloas-or-later slots; the VR duty handler skips emission (periodic + event enqueue); the periodic `VRSubmitter` stops submitting. Added `networkconfig.TestNetworkWithGloas(epoch)` test fixture (TestNetwork has no Gloas fork) + 2 tests. The VR runner stays registered but goes idle (handler emits nothing). -- **Pre-fork emission: done** (uncommitted). `Beacon.GloasForkEpoch()` + `Network.InGloasPriorWindow(slot)` (mirrors `inBoolePriorWindow`, `gloasPriorWindowEpochs = MIN_SEED_LOOKAHEAD = 1`); the prefs handler's per-tick logic extracted to `emitForTick`, which in the prior window pre-emits the first Gloas epoch's preferences (`emitForEpoch(epoch+1)`); 3 tests. **So T11 = done** (cutover both directions). Remaining: end-to-end boundary testing belongs with the broader e2e effort. -- **Cleanup (carry here):** `DefaultGasLimit` and the `feeRecipientProvider` interface live in `protocol/v2/ssv/runner/validator_registration.go` but are now also consumed by `proposer_preferences.go` (the runner). Since this fork deprecates the ValidatorRegistration runner, relocate both to a neutral file (e.g. `runner.go`) as part of the cutover so removing VR doesn't orphan them.

Until ssv-mini gains Gloas, unit tests + pointing SSV at an external ethpandaops Glamsterdam devnet cover it. `SignedProposerPreferences` stays unit/mock-only (no endpoint anywhere). **Spectests:** Gloas has no ssv-spec vectors, so the node-side Gloas types add no spec-test surface — the broader migration owns spectest decoupling, not ePBS. - -### T13 — Telemetry / metrics / logging / docs **(uses U6; parallel)** -U6 metrics (Blinded-split local-build counter; PTC/prefs reconstruction-miss counters) — **nice-to-have viz only (§8)**; the **primary validation surface is the structured DEBUG logs** for the new duties (every behavior greppable — see the §8 logs-first audit); operator docs for new config. - ---- - -## 4.

Branch & rebase workflow (ePBS starts now off `boole-fork`) - -**Decision: start ePBS now off `boole-fork`, in parallel with Boole's finalization.** ePBS must begin immediately for independent development + testing — and that's achievable now: the *node-side-complete-on-mocks* milestone (T2 BeaconNode mocks; see §4) doesn't gate on Boole landing or upstream, so ePBS can be built and exercised against mocks/devnet while Boole is being finalized. *(The alternative — wait ~2-3 weeks and build off post-Boole stage — was simpler but rejected: ePBS can't wait.)* - -**Don't build off pre-Boole `stage`:** ePBS lives in the exact files Boole heavily changes (`operator/duties/`, the committee/aggregator runners + `value_check.go`, `message/validation/*`, controller `SetupRunners`, the node-side `protocol/v2/types/{runner_role,consensus_data}.go`). *(Note `beacon/goclient/spec.go` / `networkconfig/beacon.go` are only small diffs — see U5.)* Branch off `boole-fork`. Building on `stage` and rebasing across the Boole merge later is a *rewrite*, not a rebase — every hunk on T4–T10 conflicts against Boole-restructured code, and you'd build to the pre-Boole design (re-creating the `runner_role.go`/`consensus_data.go` switches Boole already has). - -**Path:** -1. **Branch off a `boole-fork` tip now.** You get the correct baseline immediately — `RoleAggregatorCommittee=6`, `ProposerConsensusData`, the node-side switches to extend, `SSVForks{Boole}` + transition-window machinery to mirror. Build it right the first time. -2. **Track `boole-fork` until it lands (~2-3 weeks).** It's ~46 behind stage (Apr 2026), so you're developing on **Apr-stage**; `boole-fork` will be refreshed against stage before/at landing, so merge its updates into the ePBS branch as they appear and **re-run the independent tests after absorbing the refresh** (the Apr→Jun reconciliation can touch your files). Bounded by the ~2-3 week horizon, then `rebase --onto stage` at landing. -3. **When Boole merges to `stage`, move only the ePBS commits onto stage:** - ``` - git rebase --onto stage - ``` - This replays just the ePBS commits (skipping Boole's, now in stage). Clean whether Boole→stage was a **merge/FF** (Boole's commits are literally in stage) or a **squash** (the `--onto` form sidesteps the duplicated-commit conflicts a plain `git rebase stage` would hit). - -**Coordinate one thing:** nudge whoever merges Boole→stage toward a **merge-commit or fast-forward over a squash** — then even a plain rebase is clean and `--onto` is just insurance. - -**What this unblocks now:** branched off `boole-fork`, essentially all node-side ePBS work (T1, T3–T7, T9, T10, T13) can start immediately on the correct baseline. The only still-blocked items are blocked *regardless of Boole*: T8 (U1 design call) and the upstream go-eth2-client rebase / #580 endpoints (external). - -**Accepted cost:** starting now means ePBS eats a rebase across the Boole landing (the 46-commit stage reconciliation + the merge) and a re-validation pass after absorbing `boole-fork`'s refresh. That's the deliberate price of getting independent ePBS testing going in parallel — bounded by the ~2-3 week landing horizon, and the `--onto` mechanics keep the final move mechanical. - -**First incremental rebase — done** (validates the approach — small surface, not a big-bang). `boole-fork` was refreshed (#2899 + #2900); ePBS rebased onto it with two reconciliations: **scheduler.go** — boole-fork's new `dutySlotIsExecutionSlot` lateness guard was *combined* with the PTC cutoff baseline (the guard is true for PTC, so it doesn't replace it); **ptc_attester.go** — boole-fork renamed the runner completion API (`finishDuty`/`ErrRunningDutyFinished` → `markDuty*`/`ErrRunningDutySucceeded`), so abstains now use `markDutyNotRequired`. go.mod/go.sum auto-merged cleanly; #2900 also fixed a pre-existing Electra aggregate-index test. The `rebase --onto stage` at landing (step 3) still applies. - ---- - -## §7 — ePBS e2e Execution Plan (active; node-side complete) - -PTC is implemented node-side end-to-end (wire types → goclient endpoints → ekm signing → `PTCAttesterRunner` → `SetupRunners` registration → scheduler handler with the 75% trigger → message validation; ssv-spec ePBS constants via PR ssvlabs/ssv-spec#632, go.mods pinned to its commit). This supersedes the T12 sketch with the concrete plan. - -### Devnet run 2026-07-01 — §4 block production WORKS on devnet-5 (retry fix validated); new blockers -An aetheria `(proposer)` e2e run on `local_testnet_gloas` (`GLOAS_FORK_EPOCH=2`, SSV indices 64–73, **LOCAL signing**). **The original "no eligible validators" finding is closed** — the retry fix restores `📚 got duties (PROPOSER)` at loaded epochs, and the `🔬` diagnostic ladder confirmed the duty is *dispatched* (`in_committee=1, executable=1`), i.e. the remaining loss was downstream. Two downstream bugs sat behind it, both **fixed + on the branch**: -- **graffiti 400** (`e1412f656`) — `requestGloasBeaconBlock` didn't pad graffiti to 32 bytes; Lighthouse rejected the produce query. Fixed (pad to `[32]byte`, mirroring `GetBeaconBlock`). -- **local-signer `obj type is unknown: *gloas.BeaconBlock`** (`3c21d06fa`) — `LocalKeyManager.signBeaconObject`'s `DomainProposer` switch had no Gloas case (ssvsigner can't name the node's block type); now signs the SSZ root directly via `signSSZRoot`, like the other Gloas domains. - -With both, **v64's block lands on-chain** (devnet-5 slots 464, 529); §2 attestations work throughout. New findings, tracked in §1b: -- **✅ Gloas local block slashing protection — DONE.** `3c21d06fa` initially signed the root directly with no protection (a block *is* slashable, unlike PTC/prefs/envelope); now `SignBeaconObject` plumbs the slot through and the Gloas case checks `IsBeaconBlockSlashable` + records the highest proposal (serialized via `blockProposalLock`) before signing. Test: a re-proposal at the same slot is rejected. -- **devnet-6: `could not submit gloas beacon block: invalid SSZ`** — produces + signs, but the newer BN rejects the encoding → the node-side Gloas block SSZ has **drifted from devnet-6's spec** (the consensus-specs-pin-drift watchlist materializing). Blocks §4 on the *target* devnet — needs the on-wire field diff. -- **§6 envelope produce 404 (needs devnet correlation).** `executeDuty` gets the §4-decided block root and calls `GetExecutionPayloadEnvelope(slot, root)` → GET `/eth/v1/validator/execution_payload_envelopes/{slot}/{root}` (`beacon/goclient/gloas_envelope.go`). A 404 means the BN doesn't have that block/envelope yet (timing — the envelope duty may fire before the §4 block is imported) or doesn't serve the #580 endpoint. **Can't resolve node-side blind** — needs the exact 404 from a devnet run: the path the BN echoed, the response body, and whether the §4 block had landed at that point. -- **✅ §2 attestation Index rejection — DONE (was HIGH, NOT transient).** Root cause: go-eth2-client v0.27.0 hardcodes `data.Index == 0` for *all* post-Electra slots and rejects anything else with `ErrInconsistentResult` (`http/attestationdata.go`). On Gloas, `Index` is the payload-status (0=EMPTY / 1=FULL, SIP #94 §2), so a **FULL payload — the healthy case — is wrongly rejected**, failing the attestation. The devnet saw it once only because payload was mostly EMPTY during that run; on a healthy chain it would break most attestations. Fixed: `fetchAttestationData` routes Gloas slots to a hand-rolled `attestation_data` GET (`beacon/goclient/attest.go`) that skips the check and keeps the BN index; the aggregate path (`computeAttestationDataRoot`) benefits too. Trades the weighted multi-BN selection for first-client on Gloas (follow-up if reward impact matters). Test added. - -**Correction to the RS-1/RS-2 framing below:** "local signing unaffected" held only for **RS-1** (the fork_info/domain issue); local §4 **block** signing hit the *same* obj-type gap (now fixed). Both `LocalKeyManager` and `RemoteKeyManager` live in the ssvsigner module, so neither could name `*gloas.BeaconBlock`. - -### Update 2026-06-30 — §4/§5/§6 wired to the merged beacon-APIs (#580) -[beacon-APIs#580](https://github.com/ethereum/beacon-APIs/pull/580) merged 2026-06-29 and the `proposer_preferences` validator endpoint is in master, so the three endpoints that were abstract/stubbed are now implemented against the real merged paths. (go-eth2-client still has no Gloas types, so they stay hand-rolled HTTP — the typed dedup is unchanged and post-fork-OK. The older T5/T7/T8 notes below predate this and are superseded here.) -- **§5 proposer preferences** — `SubmitProposerPreferences` POSTs to `/eth/v1/validator/proposer_preferences` (JSON); the `ErrProposerPreferencesPublishUnavailable` sentinel + the runner skip-branch are removed; goclient test added. ⚠️ The *publish* path is done, but the reorg/`dependent_root` **re-emission** is a separate open issue — see the **DEFERRED** block below. -- **§4 proposer block** — produce switched v3→**v4** (`/eth/v4/validator/blocks/{slot}?…&include_payload=false`): a Gloas block is bid-only, so the response stays a bare `BeaconBlock` (no `BlockContents`). -- **§6 envelope** — produce path → plural with `beacon_block_root` as a path segment; publish → plural, posting the **blinded** body (`SignedBlindedExecutionPayloadEnvelope`, new node-side SSZ type) with `Eth-Execution-Payload-Blinded: true` (stateful — the producing BN un-blinds from cache; no blob sourcing). -- **Remaining:** the stateless `SignedExecutionPayloadEnvelopeContents` body (full envelope + blobs/KZG, for cross-BN failover — needs blob sourcing); confirm the §6 body choice (blinded vs Contents) on a Gloas devnet; the go-eth2-client typed dedup. - -### ⚠️ DEFERRED (pending SIP-94 §5 decision) — proposer-preferences re-emission -**Do not implement until SIP-94 §5 specifies the coordination rule.** Discussion opened: . - -**Issue (PR review finding #2 + SIP-94 §5, lines ~200/202/329):** SIP-94 requires re-emitting a new `ProposerPreferences` when `dependent_root` changes for a proposal slot already in the lookahead. But SSV message-validation — and Anchor's `message_validator` (`MAX_MESSAGES_PER_ROUND = 1`) — enforce **≤1 pre-consensus partial sig per `(slot, signer)`**, content-agnostic. `ProposerPreferences` pins `duty.Slot` to the **fixed proposal slot** (unlike `ValidatorRegistration`, whose slot advances), so the re-emission is a duplicate `(slot, signer)` → rejected → (1) gossip penalty on the re-emitting operator, (2) the new-root preference can't reconstruct. So today's `reEmitLookahead` (clear-all → re-emit) is **broken**, not merely incomplete: §5 reorg/`dependent_root` refresh does not work. - -**To implement once the SIP decides** (proposed in the discussion above): -- **Validation:** dedup `ProposerPreferencesPartialSig` by `(slot, signer, signing_root)` — reject a repeat root (true duplicate), allow a *new* root up to a bound `N` (proposed `4`). Every other pre-consensus type keeps ≤1 (no regression). -- **Handler** (`operator/duties/proposer_preferences.go`): re-emit only when a proposal slot's `dependent_root` actually changes (track the emitted root per slot), so the bound is spent on genuine refreshes. -- Relaxes a **cross-client** invariant → must land in SIP-94 §5 and be matched by Anchor (no §5 there yet). - -**Interim (NOT applied; flagged):** if the penalty disrupts devnet testing before the SIP resolves, suppress no-op re-emits (option a) to stop the penalty — but that does **not** refresh on reorg (a deliberate SIP deviation), so only as a stopgap. - -**Committed on `epbs-gloas`** (rebased onto the refreshed `boole-fork` — see §6): the PTC implementation (above); two review rounds — first the `DataVersionGloas` → `networkconfig` / `BeaconForkAtEpoch` TODO / SSZ-regen tidy-up, then the 11-point PTC code review (unmasked-address requests, per-client timeouts, transient-BN warn, cutoff-baselined lateness, `signSSZRoot`, abstain semantics, handler tests); the `GlamsterdamDevnet` networkconfig stub; a `.dockerignore` `tla/` exclusion. **P1 image `ssvnode:epbs-gloas` builds + runs** (verified). - -### PR review round (2026-07-01) — §2/§4/§5/§6 spec-alignment sweep -A second review pass over the ePBS submit paths (findings #1–#4). **None are functional runtime bugs** — all are spec-alignment / SIP-coordination / documentation items. Only one new TODO (§5 publish-finality); the rest confirm or cross-ref items already tracked. -- **§5 publish-finality guard — NEW TODO; the one gap with no in-code note.** SIP-94 §5 says hold publication until a proposal slot's `dependent_root` / `fee_recipient` / `target_gas_limit` are final. The runner does not: `buildProposerPreferences` reads them at emit time and the preference is published on pre-consensus quorum (`protocol/v2/ssv/runner/proposer_preferences.go`), so it can publish on a non-final `dependent_root` — and, per the re-emission DEFERRED block above, can't be corrected afterward. Reorg-gated + §5 is observational → low severity. **Done:** `KNOWN ISSUE` comment added in `buildProposerPreferences` for parity with the re-emission one; implement the finality hold only if it bites on devnet. *(Promotes the "ProposerPreferences publish-finality follow-up" from the top-of-file delete-note into a tracked item — see §1b.)* -- **§5 re-emission (finding #1) — already tracked** (DEFERRED block above). Correction to the earlier "cheap interim" idea: `reEmitLookahead` does fire on **every** reorg (not just `dependent_root` changes), but gating it on `ReorgEvent.CurrentDutyDependentRootChanged` is **not** a safe one-liner — preferences span the current **and** next epoch, and that flag covers only the current epoch (the proposer handler always re-fetches the next epoch on any reorg), so a naive gate would suppress legitimate next-epoch refreshes. The `dependent_root`-change gate therefore belongs **with** the full §5 fix (same per-slot root tracking), not as a standalone interim. -- **§4/§6 stateless Contents (finding #2) — already tracked** (§7 "Remaining" above; `include_payload=false` + blinded/stateful publish, #580-pinned). Reconciliation angle: the divergence from SIP-94's `BlockContents` / `…EnvelopeContents` flow is deliberate — it tracks the *merged* beacon-APIs#580 that real BNs serve — so the fix is a **SIP-text update** (its watchlist authorizes it), not wiring Contents. Wire Contents only if a devnet BN proves payload-stateless. -- **§2 slashing-index (finding #4) — investigated, non-issue (no code action).** The Gloas payload-status index passed to `IsAttestationSlashable` (`value_check.go`) is inert: SSV's slashing protection (eth2-key-manager `NewNormalProtection`) compares **only** `source`/`target` epochs and explicitly stores no signing roots (verified in the lib). The code comment already states this and is accurate. At most a SIP-text rationale nuance. - -### Remote (Web3Signer) signing on Gloas — broken wider than §2b tracked (RS-1/RS-2/RS-3) -A PR-review sweep of the remote-signing path: the breakage is bigger than the old §2b row (which only covered the three *new* duties). **Local signing is unaffected by RS-1** (the fork_info/domain issue) — `LocalKeyManager.SignBeaconObject` signs the root computed from the BN-sourced `domain`, never `fork_info`. *(But local §4 **block** signing hit a separate gap — the same `obj type is unknown` block-type switch — now fixed; see the 2026-07-01 devnet-run findings above. "Unaffected throughout" was wrong.)* RS-1's impact is **liveness / fail-safe** (a rejected or wrong-domain sign, never a bad on-chain sig). Order of work: **RS-1 first** (one scoped change unblocks all existing remote duties), then RS-2, then RS-3 waits on upstream. -- **RS-1 — `fork_info` carries the Fulu version on Gloas → every non-pinned remote duty gets the wrong domain (node-fixable, highest leverage — ✅ DONE).** `prepareSignRequest` stamps `ForkInfo: GetForkInfo(epoch)` on each request; `GetForkInfo` → `BeaconForkAtEpoch`, whose version list stops at Fulu, so on a Gloas slot it returns the **Fulu** fork/version. Web3Signer derives the domain from `fork_info`, so attestation/sync/aggregation/block partial-sigs sign under the wrong domain → rejected or fail reconstruction (SSV also sends a correct BN-derived `SigningRoot`, so it's a mismatch-reject or wrong-domain sig — either way fail-safe). **Pinned domains exempt:** voluntary-exit (Capella) and validator-registration (genesis) override `fork_info`, so they keep working. **Fix (scoped, no ripple):** resolve the Gloas fork *inside `GetForkInfo`* via the **existing `ForkAtVersion(spec.DataVersionFulu+1)`** interface method — it returns the configured Gloas fork (the real `gloasForkVersion`, populated from the BN spec in `beacon/goclient/spec.go`); gate on `epoch ≥` its fork epoch (= `IsGloas`). **No interface change, no direct `Forks` access.** Do **not** extend `BeaconForkAtEpoch`: its `spec.DataVersion` return feeds ~8 callers (committee/aggregator/goclient submission tags) that deliberately cap at Fulu (its own `TODO(gloas)`). **Module boundary:** the ssvsigner module has its own go.mod and **can't import `networkconfig.DataVersionGloas`**, so it defines the Gloas data version locally as `spec.DataVersionFulu+1` (mirroring the placeholder). `RemoteKeyManager.beaconConfig` is `networkconfig.Beacon` in production (`operator/node.go`); the ssvsigner's own `beaconcfg.Config` (e2e) has the same Fulu cap but only matters if it ever computes signing `fork_info`. **Cross-system (devnet-confirm):** Web3Signer's `compute_domain` is generic over the version bytes, so the correct Gloas `fork_info` should suffice with no Web3Signer Gloas support — the only non-in-repo fact; confirm against a live Web3Signer. -- **RS-2 — §4 remote block signing: NOT a simple "add a case" (module boundary + cross-system; DEFERRED).** `handleDomainProposer` → `ConvertBlockToBeaconBlockData` type-switches on the block, but the Gloas block is `protocol/v2/types/gloas.BeaconBlock` (main module) and **the ssvsigner module has its own go.mod, doesn't require the main module, and imports no `gloas`** — so it *cannot* add a `case *gloas.BeaconBlock:`; the block falls through to `default: "obj type is unknown"` (`ssvsigner/web3signer/block_data.go`). *(The signing root is still computed correctly via `ComputeETHSigningRoot(obj, domain)` on the `ssz.HashRoot` interface; only `req.BeaconBlock` — the header BLOCK_V2 needs — can't be built.)* **Fix (design decision, spans both modules):** the node-side proposer path passes the **block header** (`phase0.BeaconBlockHeader`, a go-eth2-client type nameable in ssvsigner; `HTR(header) == HTR(block)`, so the signing root is unchanged) instead of the full Gloas block; the converter gains a `case *phase0.BeaconBlockHeader:`; `handleDomainProposer` supplies the Gloas version. **Cross-system:** whether Web3Signer accepts a Gloas-version BLOCK_V2 is unverified (may gate on Web3Signer Gloas support). Bigger than RS-1 and cross-system-gated → **deferred**; RS-1 already unblocks every remote duty except the §4 block. -- **RS-3 — §3/§5/§6 have no Web3Signer request type (upstream-blocked; already in §2b).** The PTC/preferences/envelope arms return descriptive errors + `TODO(gloas)`; `SignRequest` has no matching field. Gated on Web3Signer adding `payload_attestation` / `proposer_preferences` / `execution_payload_envelope` types; local-sign meanwhile (bounded by `f`). Point the `TODO(gloas)` arms at the upstream Web3Signer issue. - -### Gate check — PASSED -Make-or-break question for the public-devnet path: do the Gloas devnet CL clients expose the **beacon-API PTC validator endpoints**? (A Gloas chain can run with built-in VCs doing PTC internally without exposing them to an external VC like SSV.) They do: -- **Lodestar** `packages/api/src/beacon/routes/validator.ts` defines `getPtcDuties` (`/eth/v1/validator/duties/ptc/{epoch}`) and `producePayloadAttestationData` (→ `gloas.PayloadAttestationData`) — the exact URLs `beacon/goclient/ptc.go` calls. **Lighthouse** has the endpoints in `common/eth2` + a `payload_attestation_service`. -- `ethpandaops/glamsterdam-devnets` runs purpose-built Gloas images of every major client (`lighthouse`, `lodestar`, `prysm`, `teku`, `grandine`, …). **Live devnet = devnet-6** (as of 2026-06-30): `GLOAS_FORK_EPOCH: 30`, chain `7052886157`, genesis `1782386940` (≈ 2026-06-25 11:29 UTC) ⇒ **Gloas/ePBS active since ≈ 2026-06-25 14:41 UTC**. **devnet-5 is now Off; devnet-0..4 torn down** (dashboards 404). Devnets reset frequently and the repo README status table lags — **probe `https://glamsterdam-devnet-N.ethpandaops.io/` (→ 200) to find the live one, and re-check before every run** (it already moved 5→6). - -→ SSV operators pointed at a Lodestar/Lighthouse Gloas-devnet BN can run the full duties→produce→submit PTC flow. **The `devnet` initiative is feasible now.** - -### Shared prerequisites -- **P1 — PTC node image: DONE.** `ssvnode:epbs-gloas` builds + runs (verified). **No `GOPRIVATE` needed** for the build — the branch-pinned ssv-spec is in both go.sums, so `go mod download && go mod verify` resolves it via the public proxy without the sum-DB (GOPRIVATE is only for `go get`/`tidy`). Keep `tla/` out of the build context (`.dockerignore`) or local TLA+ scratch bloats `COPY . .`. -- **P2 — ssv-spec #632 merged** → re-point both go.mods at the cut version (drops the branch-pin; `go get`/`tidy` then no longer need `GOPRIVATE`). -- **P3 — DONE.** The deferred refinements: handler dependent-root/reorg refresh (committed) · PTC message lateness TTL + per-validator duty-count cap (committed) · PTC duty-assignment check (uncommitted) — a `dutyStore.PTC` (`Duties[gloas.PTCDuty]`) entry, with the handler reworked to broad-record every participating validator's duty in both operator+exporter modes (mirrors proposer/sync; `InCommittee` marks this node's own for execution) and an `IsEpochSet`-tolerant `RolePTCAttester` arm in `validateBeaconDuty`. Behavior is now sound under real-network reorgs/timing. -- **Observability (devnet watch):** PTC non-convergence (broadcast but no quorum — peers diverged on payload presence near the boundary) calls no duty marker, so `watchDutyOutcome` reports the generic "⚠️ likely stuck" at slot end. Framework-level (the runner has no slot-end hook), not PTC code; gauge the log frequency on the live devnet (devnet-6) before adding a distinct non-convergence outcome (tracked as §8 G5). - -### Two independent initiatives — run in parallel -`local_testnet` and `devnet` are **separate, independent validation initiatives** — neither blocks the other, and we want both running in parallel. They share only the build foundation (P1–P3 above: the `ssvnode:epbs-gloas` image + branch) and the greppable-log pass/fail signal; past that they diverge entirely (own networks, own client images, own validator sets, own lifecycle). -- **`local_testnet`** — hermetic, fully controlled; we own the whole validator set ⇒ **PTC duty hits every slot**. Already IMPLEMENTED + PROVEN. The fast inner-loop + CI signal — answers *"is our code correct?"*. -- **`devnet`** — the public ethpandaops multi-client net; **real 512-member PTC** against clients we don't control. The external-interop bar; needs infra (contract deploy + validators). Answers *"does it interop?"*. - -Do both: mock-green ≠ local-green ≠ interop-green. - -### Initiative `devnet` (Track 1) — public glamsterdam-devnet -1. **Devnet = devnet-6** (the live one as of 2026-06-30; devnet-5 now Off — **re-probe before each run**, see Gate check). **Sanity-check first:** `GET /eth/v1/config/spec` (confirm `GLOAS_FORK_EPOCH` is past the current epoch) + hit a PTC endpoint on a devnet-6 BN.

Spec matches the PR's wire values: `GLOAS_FORK_EPOCH:30`, `PTC_SIZE:512`, `PAYLOAD_ATTESTATION_DUE_BPS:7500` (=75% cutoff), `MAX_PAYLOAD_ATTESTATIONS:4`, domains `PTC_ATTESTER:0x0c`/`BEACON_BUILDER:0x0b`/`PROPOSER_PREFERENCES:0x0d`. `POST /eth/v1/validator/duties/ptc/{epoch}` → **200** (route live). **~3909 active validators** ⇒ PTC picks 512/slot, so each validator hits PTC ~every 8 slots (~90s) — frequent even with a handful of SSV validators (revises the earlier "PTC is rare on a shared net" caveat for devnet-6). -2. **`networkconfig` entry — committed + refreshed (2026-06-30):** `GlamsterdamDevnetSSV` in `networkconfig/glamsterdam-devnet.go` — an `&SSV{}` only (the Beacon side — genesis, fork schedule incl. `GLOAS_FORK_EPOCH` — comes from the BN at runtime; no `&Network{}` needed), registered + selectable as `glamsterdam-devnet` (domain `{0,0,9,0}`, `Boole:0`). Header now points at **devnet-6** (`7052886157` / `1782386940`) and `TotalEthereumValidators` is filled from the verified live count (**3909**). **Still `TODO(e2e)`** (devnet-specific, reset on every devnet; fill after steps 3-4): `RegistryContractAddr` + `RegistrySyncOffset` (contract deploy), `Bootnodes` (operator ENRs). -3. **Deploy SSV contracts** on the devnet EL; register 4 operators. -4. **Validators** — deposit via the devnet faucet/deposit contract → await activation → split keys into shares → register validators+shares on the SSV contract. -5. **Run 4 operators** (P1 image) on the devnet config; **assert the greppable operator logs** (`fetched PTC duties` → `successfully submitted payload attestation`) as the automatable pass/fail signal; the BN `payload_attestations` pool is a secondary on-chain cross-check. -- Risks: devnet resets/instability; validator activation latency; SSV contract deploy on a non-standard chain; per-client beacon-API PTC completeness (Lodestar/Lighthouse confirmed — verify the specific BN combo used). - -### Progress checklist -**`local_testnet` initiative:** ✅ **DONE** — automated Loki-based `(ptc)` suite **merged to aetheria `main` 2026-06-30** (#123 / #126 / #127 + ssv-mini#34 + ethereum2-monitor#504); #128 (kurtosis-native Loki) is the one open follow-up. Full checklist: [aetheria#125](https://github.com/ssvlabs/aetheria/issues/125). - -**`devnet` initiative:** -- [x] **1 · Pick & verify the live devnet** — devnet-6 verified live 2026-06-30 (see step 1): epoch ~1118 (Gloas active), PTC route 200, open BN/EL endpoints recorded, spec wire-values match the PR. -- [x] **2 · `networkconfig` stub refreshed** — `glamsterdam-devnet.go` header → devnet-6 + `TotalEthereumValidators=3909` (verified). Remaining fields tracked in step 5. -- [ ] **3 · Deploy SSV contracts on the devnet-6 EL + register 4 operators** → record `RegistryContractAddr` + deployment block. -- [ ] **4 · Validators** — deposit (devnet deposit contract `0x00000000219ab540356cBB839Cbe05303d7705Fa`) → await activation → split keys into 4 shares → register validators+shares on the SSV contract. -- [ ] **5 · Fill remaining stub TODOs** — `RegistryContractAddr` + `RegistrySyncOffset` (from 3), `Bootnodes` (operator ENRs from 3). -- [ ] **6 · Run 4 operators** — `Network: glamsterdam-devnet`, `BeaconNodeAddr`=devnet-6 CL, `ETH1Addr`=devnet-6 EL (WS). -- [ ] **7 · Verify PTC** — grep all 4 operators: `Gloas (ePBS) fork scheduled` → `fetched PTC duties` → `✔️ successfully submitted payload attestation`; abstain only on missed slots; cross-check the BN `payload_attestations` pool. -- [ ] **8 · Confirm §2 aggregate payload-status index (review finding #4)** — `computeAttestationDataRoot` (`beacon/goclient/aggregator.go`) fetches the attestation data fresh from the aggregator's own BN and keeps that BN's payload-status index, not the QBFT-decided index the committee signed. Confirm the aggregate fetch matches the signed index across BNs (low risk — payload status should be settled by aggregation time — but a cross-BN mismatch would silently miss the aggregate). - -### `devnet` — operator run config (env vars; own EL/CL, no config file) -Config is `cleanenv`-based: a node started without `--config` reads purely from env (`ReadEnv`), and env overrides a file when one is passed — so the whole operator can be driven by env vars. Minimal set per operator (we run our own EL/CL): - -| Env var | Value / note | -|---|---| -| `NETWORK` | `glamsterdam-devnet` (selects `GlamsterdamDevnetSSV`; beacon genesis/fork schedule incl. `GLOAS_FORK_EPOCH` are read from the BN) | -| `BEACON_NODE_ADDR` | **required** — your CL HTTP URL(s); **Lighthouse/Lodestar preferred** for the full PTC endpoint set; `;`-separated for multiple | -| `ETH_1_ADDR` | **required** — your EL **WS** URL(s); `;`-separated for multiple | -| `OPERATOR_KEY` | this operator's private key (or `PRIVATE_KEY_FILE`). **Local signing only** — ssv-signer / Web3Signer PTC signing is unsupported (bounded by f), so don't use the remote-signer path for this test | -| `DB_PATH` | per-operator DB dir (default `./data/db`) | -| `LOG_LEVEL` | `debug` — the PTC/fork logs are the pass/fail signal | -| `NETWORK_PRIVATE_KEY` | optional P2P identity (auto-generated if unset); set one per operator to get stable ENRs for the stub's `Bootnodes` | -| `METRICS_API_PORT` / `EVENTS_PATH` | optional (metrics port; local-events injection) | - -Once the 4 nodes are up, harvest their ENRs into the stub `Bootnodes` (or pin a known `NETWORK_PRIVATE_KEY` per node) so the cluster discovers itself. - -### Initiative `local_testnet` (Track 2) — ssv-mini / aetheria local Gloas net — **MERGED to aetheria `main` 2026-06-30; automated `(ptc)` suite live (see result below). Tracking: [aetheria#125](https://github.com/ssvlabs/aetheria/issues/125)** -**Correction:** the earlier claim that `ethpandaops/ethereum-package@6.1.0` "has no Gloas/Glamsterdam fork (only up to Fulu+BPO)" is **wrong**. 6.1.0's `network_params.yaml` ships `gloas_fork_epoch` (+ the §1 quarter-slot `*_due_bps_gloas` timings) and threads it through `input_parser → el_cl_genesis_generator → values.env.tmpl`; its own CI test `.github/tests/fulu-genesis.yaml` runs `fulu_fork_epoch: 0` + `gloas_fork_epoch: 2`. So a local Gloas net is configurable **today** — no upstream wait. The only real blocker was Gloas-capable client images, solved by the ethpandaops `glamsterdam-devnet-5` builds (all EL/CL clients tagged). - -Built across these PRs — **all merged 2026-06-30** (the local Gloas net reuses `local_testnet`'s on-chain identity — same contracts/validators — so no DB-seed duplication; Gloas is beacon-driven, read from the BN's `GLOAS_FORK_EPOCH`, so the SSV node needs no change). The automated assertion layer (Loki `(ptc)` suite #127, dbtest fail-fast #126) and the one remaining piece (#128) are tracked in [aetheria#125](https://github.com/ssvlabs/aetheria/issues/125): -1. **ssv-mini [#34](https://github.com/ssvlabs/ssv-mini/pull/34)** — `params-gloas.yaml` + `make run-gloas`: Fulu at genesis → Gloas at epoch 2, `glamsterdam-devnet-5` EL/CL images (Gloas-capable; the local net **pins these independently of whichever public devnet is live** — bump only if a later devnet build carries a client fix you need), genesis-generator pinned to `6.0.8` (6.1.0's default `5.3.5` predates Gloas), `boole_epoch: 0`. Usable standalone today for direct PTC observation (greppable SSV logs = the automatable signal; dora as a manual visual aid): `SSV_COMMIT=epbs-gloas make prepare && make run-gloas`. -2. **ethereum2-monitor [#504](https://github.com/ssvlabs/ethereum2-monitor/pull/504)** (scoped in #503) — Gloas block decoding (go-eth2-client v0.28.x can't decode Gloas): a reactive raw-JSON fallback in `beacon.FetchBlock` — no SSZ, no shared types. Re-enables E2M attestation validation on a Gloas chain. -3. **aetheria [#123](https://github.com/ssvlabs/aetheria/pull/123)** — a `local_testnet_gloas` network that routes to `params-gloas.yaml`, reusing local_testnet's identity; E2M capture made best-effort. `make run NETWORK=local_testnet_gloas TESTS='(event)'`. **Plus an E2M-coordination fix (2026-06-28, committed on `epbs/local-testnet-gloas`):** when `monitor-api` is absent the orchestrator now also sets the per-flow `e2m=false` (not just leaving `E2MURL` at a stale default), so the executor *skips* E2M and the `(event)` flow passes (on-chain lifecycle only) instead of hard-failing and tearing down. - -### Sequencing — the two initiatives run in parallel (no cross-dependency) -- **Shared foundation (done):** P1 image + the `networkconfig` stub — the *only* thing both initiatives share; after it they proceed independently. -- **`local_testnet` (DONE — keep green):** implemented + PROVEN (below). Re-run on each branch tip / in CI as the fast regression signal; owns its own client images + validator set. -- **`devnet` (infra, your hands — start in parallel):** devnet-6 probe + sanity check → SSV contract deploy + 4 operators → validators → fill the 3 stub TODOs → run + verify PTC via the greppable logs. Does **not** depend on `local_testnet`; can start any time. - -**`local_testnet` merge/enable order — ✅ completed (all merged 2026-06-30); kept for reference:** -1. **ssv-mini #34** — mergeable now; `make run-gloas` works standalone (monitor off; verify ePBS via greppable SSV logs — dora as a visual aid). Its `params-gloas.yaml` keeps `monitor.enabled: false` deliberately, so it's mergeable before E2M ships Gloas support. -2. **ethereum2-monitor #504** — merge; then rebuild the monitor image (ssv-mini `make prepare-monitor`, built from `../ethereum2-monitor`). -3. **ssv-mini follow-up** — once #504 is in the monitor image, flip `monitor.enabled: true` in `params-gloas.yaml`. This turns on E2M attestation validation on the Gloas chain. *(This is the easy-to-forget step — it's intentionally deferred out of #34 so #34 stays mergeable today.)* -4. **aetheria #123** — merge last; `local_testnet_gloas` then runs the full executor `(event)` flow with E2M. Its E2M capture is best-effort, so it also works between steps 1 and 3 — just without E2M validation until the monitor is re-enabled. - -Independent: aetheria #123 and ssv-mini #34 don't depend on #504 to *function* (E2M just stays skipped); #504 + step 3 only add E2M validation. The PTC/proposer/envelope ePBS behavior itself is verifiable from step 1 via greppable node logs (dora as a visual aid). - -### `local_testnet` — e2e RESULT (2026-06-28): full dormant → transition → executing PROVEN on the local Gloas net -Ran `aetheria local_testnet_gloas` end-to-end (host orchestrator + seeded DB + the `params-gloas.yaml` enclave, `node/ssv:epbs-gloas`, 4 operators). The SSV node's complete ePBS PTC lifecycle was observed live across the epoch-2 fork: -- **Dormant (epoch 0–1):** `DutyScheduler` starts `PTC_ATTESTER` + `PROPOSER_PREFERENCES`; they react to validator-index changes ("re-fetching PTC duties on next tick") but execute nothing. Boole active (`/ssv//boole/*` subnets). -- **Transition (epoch 2 / slot 64):** all 4 nodes' `PTC_ATTESTER` activates → `POST /eth/v1/validator/duties/ptc/2`. The first call at the exact fork-boundary slot returns CL `500 BeaconStateError(IncorrectStateVariant)` (lighthouse devnet-5: state not yet in the Gloas variant); the node's per-slot re-fetch **retries the next slot and succeeds**. Relevant to the `devnet` initiative too: expect a one-slot 500 at a node's first Gloas slot — the existing refetch absorbs it, no code change needed. -- **Executing (epoch 5 / slot 166):** with a validator held continuously active, `🔧 executing validator duty PTC_ATTESTER-e5-s166-v64` → `GET payload_attestation_data/166` → **`✔️ successfully submitted payload attestation` on all 4 operators**. An earlier duty at slot 148 correctly **failed-safe** — CL `404 No block received` on a missed slot (~80% block production on the devnet), so a validator's one-duty-per-epoch lands within an epoch or two; this is expected, not a node bug. - -**Two corrections to the prior handoff:** -1. **The "ENCRYPTION_KEY_HASH secret" blocker was a non-issue.** The working key (`SSV-AUTOMATION-…-KEY`) was already in the aetheria main checkout's `orchestrator/.env`; the stuck session was running from a different (`/tmp`) checkout whose `.env` carried the `aetheria-encryption-key` placeholder. No team secret is needed for the local Gloas run — config-gen decrypts the seed cleanly with the in-repo key (verified by decrypting the seed ciphertext directly and by a clean live config-gen). -2. **E2M coordination fix** added to #123 (see the #123 bullet above) — without it a plain `(event)` on Gloas false-fails at bulk E2M validation even though the on-chain + PTC behavior is correct. - -### PR #2855 (MEV timing games) — hold; merge ePBS first -**Decision:** do not merge #2855 for now — merge ePBS first, then reconsider #2855's role. - -Rationale: ePBS removes the *out-of-protocol* apparatus #2855's doc configures (mev-boost/commit-boost relay polling — gone post-Gloas), but **not** the underlying "select the bid as late as the deadline allows" dynamic. Post-Gloas that lever relocates: for a non-self-building proposer it moves *into SSV* (when it calls `GetGloasBeaconBlock`) and/or the BN's own bid selection, while the larger late-MEV lever moves to the builder (or SSV's §6 envelope timing when self-building). So #2855's SSV-side knob (`ProposalSoftDeadline`) likely **carries over with re-derived bounds** for the tighter 25%-of-slot (vs 33%) attestation deadline — a reduced job, not a removed one — which is what to re-evaluate once ePBS lands. - -- `ProposerDelay`: **keep, do not deprecate** — the live pre-Gloas MEV knob and, with #2855 on hold, the only one. Re-tune its role/bounds for ePBS rather than removing it. -- Docs: EXTERNAL_BUILDERS.md ePBS forward-pointer added (#2901); the MEV_CONSIDERATIONS.md full ePBS rewrite is deferred to the mainnet track. - -### ProposerDelay → ePBS split — DONE (#2901) -Fork-gated per-slot (`IsGloasAtSlot`): -- **Pre-ePBS:** `ProposerDelay` + `AllowDangerousProposerDelay` unchanged, but apply **pre-fork only** (today `ProposerDelay` fires under Gloas too — it sits before the `IsGloasAtSlot` branch in the proposer runner, so this is a real carve-out). -- **Post-ePBS:** `ProposerDelay`/`AllowDangerousProposerDelay` have no effect; a new **`ProposerDelayEPBS`** takes over with similar behavior, **hard-capped at 1000ms** (startup-rejected above it — no `AllowDangerous` override, for simplicity), **default 0** (opt-in). Tighter ~25% deadline + smaller/uncertain MEV upside ⇒ no aggressive escape hatch; default-off until live-devnet measurements justify a value. -- Self-document the flag in #2901 (config-struct comment + `config.example.yaml`); the MEV_CONSIDERATIONS.md prose update lands later in #2855 once its shape is final. -- Proposer budget under Gloas = `ProposerDelayEPBS` + the QBFT round timer (audit ① below). NOTE (corrected): the pre-Gloas `proposalSoftTimeout` does **not** apply under Gloas — the produce path uses `firstClientResult` and bypasses it (audit ④), so there's no proposalSoftTimeout↔delay coupling to tune. - -### Gloas timing audit — full inventory (thirds → quarters) -Every hardcoded slot-relative timeout/deadline classified so none is missed when `IntervalDuration` goes thirds→quarters. Scope: duty-execution + beacon-fetch + QBFT timing. (Out of scope by nature: p2p timeouts and message-validation lateness — those are slot-*count* / fixed-margin based, not interval-fraction, so the quarters change doesn't move them.) - -**Auto-scales via `IntervalDuration` — OK, no change:** aggregation fetch (`beacon/goclient/aggregator.go:95`), sync-contribution delay (`sync_committee_contribution.go:135`), scheduler exec delays (`operator/duties/scheduler.go:362,444`), indices-change deadlines (`proposer.go:121`, `attester.go:131`), 50% aggregator mark (`aggregator_committee.go:236`), `PayloadAttestationCutoff`=3/4 (`networkconfig/beacon.go:66`). - -**Hit-list — needs Gloas adjustment:** -1. **QBFT round timer — DONE (#2901).** `round1HeadStart` now derives from `IntervalDuration` (1× committee, 2× aggregator), so head starts track quarters under Gloas; `RoundTimeout`/`EstimatedRoundAt` (+ the message-validation `estimatedRoundAt`) pass `IntervalDuration(slot)`; pre-Gloas behavior is byte-identical (interval = `slotDuration/3`, verified by unchanged test expectations + a new Gloas case). **`QuickTimeout` kept at 2s** — it's a fixed round-trip budget, not a slot fraction — so the Gloas proposer is effectively round-1-must-succeed; shrinking it to restore the round-2 fallback is deferred to devnet RTT data (documented at the `QuickTimeout` const). (`QuickTimeoutThreshold`=8 / `SlowTimeout`=2min → leave.) -2. **`weightedAttestationData{Soft,Hard}Timeout` — DONE.** Scaled proportionally to the attestation window via a new `scaleToAttestationWindow(base, slot)` helper (integer `base * 3 / intervalsPerSlot`): unchanged pre-Gloas (1/3 window), ×3/4 from Gloas (1/4 window, ~4s→3s). Applied to the hard + soft fetch budgets and their soft/2 (scoring) + soft/4 (block-header) derivatives. Assumes BN response timings are fork-independent (the stated decision); nil-guarded for pre-init. -3. **Attestation refetch — DONE.** `minTimeForRetry`/`refetchDelay`/`refetchTimeout` scaled by the same `scaleToAttestationWindow` helper (the 100ms poll ticker is fork-agnostic granularity → left). - -**Checked — not applicable / corrected:** -4. **`proposalSoftTimeout`** (`options.go:47`, default 1800ms; min 500ms) — *not* a Gloas issue. The Gloas produce path uses `firstClientResult` (`gloas_proposer.go:28`) and bypasses it (pre-Gloas-only). The real Gloas question is a *design* one — should Gloas produce do multi-BN bid comparison / a soft timeout at all? — tied to `ProposerDelayEPBS`; forward-looking, not a constant to lower. -5. **§6 envelope / PTC / proposer-preferences runners — clean.** No hardcoded slot timing; all deadline-driven (deadline injected by the scheduler/executor). - -**Fork-agnostic — leave (verified):** `commonTimeout` 5s / `longTimeout` 60s (general HTTP); `ptcHTTPClient` has no client timeout — ctx-bounded (PTC fetches use `commonTimeout`, bounded by the slot-end duty deadline; Gloas produce/submit bounded by the proposer ctx); `blockPropagationDelay` 300ms (network propagation); scheduler `slotDelay≥100ms` drift threshold (L496/553); `attest.go:430` 100ms poll granularity; `observability.go:148` 1ms log threshold; queue micro-timings (`inboxReadFrequency` 1ms, `retryDelay` 25ms, ttlcache 10min, `SlotDuration/retryDelay` retry count); slotticker (SlotDuration boundary ticker); `DefaultSlotDuration` 12s. - ---- - -## §8 — Fork-transition monitoring + logs-first observability audit - -### Observability principle — logs-first (DEBUG-complete) -**Every ePBS behavior we care about MUST be verifiable from DEBUG logs alone.** OTel metrics are *nice-to-have* — dashboards/aggregation only, never the sole evidence a behavior happened (there are no in-repo dashboards anyway, and `local_testnet` was verified purely from logs). Rule: any metric that records an ePBS decision/outcome must have a matching log (DEBUG or higher) carrying the same fact. The audit below closes the cases where this doesn't yet hold. - -### Fork-transition monitoring — proven on `local_testnet_gloas`; re-apply on devnet-6 / Hoodi / Sepolia -The dormant→transition→executing flow is already PROVEN on the local Gloas net (the `local_testnet` RESULT above, epoch-2 fork, verified from logs). This is the generalized watch layer for any fork. - -**#1 blindspot:** the Gloas fork epoch is **not** in SSV config — it is read from each BN's `/eth/v1/config/spec` (`GLOAS_FORK_EPOCH`, `beacon/goclient/spec.go:259`), **with no startup log**. If a BN doesn't schedule it / BNs disagree, the node silently stays pre-Gloas (`IsGloas=false`, `IntervalDuration` stays /3) — no error, nothing ePBS fires. → pre-flight #1 + audit **G1**. - -**Control/scale per network:** `local_testnet_gloas` (the `local_testnet` initiative, DONE) sets the fork via `params-gloas.yaml` `gloas_fork_epoch: 2` — fully controllable. `glamsterdam-devnet-6` (the `devnet` initiative) — epoch from the BN, real 512-member PTC. Hoodi/Sepolia — unscheduled today (`FarFutureEpoch`); monitor-only once they schedule Gloas (same watch, no timing control). - -**Pre-flight (T-minus a few epochs):** (1) every BN's `GLOAS_FORK_EPOCH` equal + not far-future [the node can't self-check this — G1]; (2) every BN serves the 8 Gloas routes (block produce/publish, envelope get/publish, PTC duties/data/submit, proposer-dependent-root); (3) `ProposerDelayEPBS` ≤ 1s (else boot-abort); (4) validator set actually hits proposer + PTC selections in-window; (5) baseline pre-fork (`/3`, zero ePBS roles) for a clean delta. - -**Boundary quirks (from `local_testnet` — expect on any fork):** the first Gloas slot may return CL `500 BeaconStateError(IncorrectStateVariant)` → the per-slot refetch absorbs it (no code change); a missed proposal slot → CL `404 No block` → PTC fails-safe, the one-duty-per-epoch lands within an epoch or two. - -**Per-section primary watch** (log = source of truth; metric in parens): -- **§1 timing** — attestation submit rate holds across `/3→/4`; red flag: `⚠️ late duty execution` bursts (PTC lateness measured from the 75% cutoff).

From a32cd247ec9a476c8435d2aa40e8a2c865c347d5 Mon Sep 17 00:00:00 2001 From: iurii Date: Thu, 2 Jul 2026 16:19:48 +0300 Subject: [PATCH 097/228] =?UTF-8?q?fix(gloas):=20key=20=C2=A74=20block=20s?= =?UTF-8?q?lashing=20protection=20to=20the=20signed=20block's=20slot?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Gloas proposer path signed a block under block.Slot but keyed slashing protection to the plumbed duty slot, and the value check never bound the two. A malicious QBFT leader could decide a value whose block.Slot differed from cd.Duty.Slot, harvesting a validator signature over a block for a slot the slashing DB was not tracking — a cross-slot equivocation it would not catch. - value check: enforce block.Slot == cd.Duty.Slot on the Gloas proposer arm, and return the decoded block so CheckValue stops decoding it twice. - ekm: match a structural slashableBeaconBlock interface (fail loud on any other proposer object instead of blindly signing), key the check+record to the block's own slot, and guard the far-future bound locally — the plumbed slot no longer bounds it — mirroring the remote signer. Drop the now-unused plumbed slot from the local signer. - duties: downgrade the already-passed-slots proposer-fetch log from Warn to Debug (false-alarms on routine reorg / indices-change re-fetches). Adds regression tests for the slot-mismatch rejection, block-slot-keyed slashing protection, fail-loud on unknown objects, and the far-future guard. --- operator/duties/proposer.go | 5 +- protocol/v2/ssv/value_check.go | 50 ++++++++++-------- protocol/v2/ssv/value_check_test.go | 8 +++ protocol/v2/types/gloas/beacon_block.go | 4 ++ ssvsigner/ekm/local_key_manager.go | 44 +++++++++++----- ssvsigner/ekm/local_key_manager_test.go | 69 ++++++++++++++++++++----- 6 files changed, 131 insertions(+), 49 deletions(-) diff --git a/operator/duties/proposer.go b/operator/duties/proposer.go index 18d189a98d..fb9d07c71a 100644 --- a/operator/duties/proposer.go +++ b/operator/duties/proposer.go @@ -528,9 +528,10 @@ func (h *ProposerHandler) logFetchDispatchDiagnostic(logger *zap.Logger, targetE ) } - // Fetched in-committee duties for slots that already passed — a guaranteed miss (fetched too late). + // Fetched in-committee duties for slots that already passed — a guaranteed miss only on a first fetch; + // on routine re-fetches (reorg, validator-indices change) it is expected, so log at Debug, not Warn. if len(alreadyPassed) > 0 { - logger.Warn("🔬 proposer fetch: in-committee duties for already-passed slots (diagnostic)", + logger.Debug("🔬 proposer fetch: in-committee duties for already-passed slots (diagnostic)", zap.Uint64("target_epoch", uint64(targetEpoch)), zap.Uint64("current_slot", uint64(currentSlot)), zap.Int("in_committee_total", inCommittee), diff --git a/protocol/v2/ssv/value_check.go b/protocol/v2/ssv/value_check.go index bbb51d675a..a3b0373e4d 100644 --- a/protocol/v2/ssv/value_check.go +++ b/protocol/v2/ssv/value_check.go @@ -306,20 +306,16 @@ func NewProposerChecker( } func (v *proposerChecker) CheckValue(value []byte) error { - cd, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleProposer, v.validatorPK, v.validatorIndex) + cd, gloasBlock, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleProposer, v.validatorPK, v.validatorIndex) if err != nil { return err } var slot phase0.Slot - if v.beaconConfig.IsGloasAtSlot(cd.Duty.Slot) { - // Gloas blocks have no spectypes block version; GetBlockData can't decode them, so read the - // slot from the node-side block directly. - block, decErr := gloas.DecodeBeaconBlock(cd.DataSSZ) - if decErr != nil { - return fmt.Errorf("could not decode gloas block: %w", decErr) - } - slot = block.Slot + if gloasBlock != nil { + // Gloas blocks have no spectypes block version; checkValidatorConsensusData already decoded the + // node-side block and verified block.Slot == duty slot, so reuse it rather than decode again. + slot = gloasBlock.Slot } else { blockData, _, bdErr := cd.GetBlockData() if bdErr != nil { @@ -352,7 +348,7 @@ func NewAggregatorChecker( } func (v *aggregatorChecker) CheckValue(value []byte) error { - _, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleAggregator, v.validatorPK, v.validatorIndex) + _, _, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleAggregator, v.validatorPK, v.validatorIndex) return err } @@ -375,47 +371,59 @@ func NewSyncCommitteeContributionChecker( } func (v *syncCommitteeContributionChecker) CheckValue(value []byte) error { - _, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleSyncCommitteeContribution, v.validatorPK, v.validatorIndex) + _, _, err := checkValidatorConsensusData(value, v.beaconConfig, spectypes.BNRoleSyncCommitteeContribution, v.validatorPK, v.validatorIndex) return err } +// checkValidatorConsensusData decodes and validates a ProposerConsensusData value.

A partial arriving before the local duty (re)started was only replayed by the queue for ~1 slot and then dropped — unrecoverably, since the sender never re-broadcasts and message validation dedups a same-root re-broadcast by signing root. Every indices-change re-emission also replaced the sub-runner and discarded the partials it had collected. On a devnet this starved every first-§5-epoch duty (the Gloas fork-boundary epoch) on all operators: each node held fewer than quorum partials and logged 'duty did not complete before slot end'. Runner (dispatcher): - stash every §5 partial per proposal slot (bounded by committee × the wire's distinct-root cap, deduplicated, pruned with past slots) and replay the stash into every (re)started sub-runner, so quorum forms regardless of emission order and container replacement. - conclude a replaced sub-runner as not-required (superseded, not stuck), and carry the already-submitted preference over so an unchanged re-emission is idempotent: no duplicate gossip broadcast (peers would reject it) and no duplicate beacon-node submit; a dependent_root change still re-signs, re-broadcasts and resubmits. Outcome watcher: a §5 duty legitimately keeps converging until its proposal slot, so its stuck horizon is that slot's start rather than the emission slot's end (which produced false 'stuck' warnings for duties that could still complete). Scheduler: - give each §5 duty an execution window running to the end of its own proposal slot (was: end of the emission slot), matching the watcher. - skip assignments whose proposal slot is already reached — their preference is moot and peers would reject the partials as late. - force a one-time lookahead recheck on the first Gloas tick, like a reorg would: if the CL's reported dependent_root for the boundary epoch shifts at the fork transition, the pre-fork emission is refreshed; with an unchanged root the recheck is a no-op. --- operator/duties/proposer_preferences.go | 31 +++- operator/duties/proposer_preferences_test.go | 99 +++++++++- operator/duties/ptc_attestation_test.go | 11 +- .../v2/ssv/runner/proposer_preferences.go | 115 +++++++++++- .../ssv/runner/proposer_preferences_test.go | 171 ++++++++++++++++++ protocol/v2/ssv/runner/runner.go | 13 +- .../v2/ssv/runner/runner_deadline_test.go | 19 ++ 7 files changed, 438 insertions(+), 21 deletions(-) diff --git a/operator/duties/proposer_preferences.go b/operator/duties/proposer_preferences.go index 8af4eec139..dd28c460e1 100644 --- a/operator/duties/proposer_preferences.go +++ b/operator/duties/proposer_preferences.go @@ -26,6 +26,10 @@ type ProposerPreferencesHandler struct { // recheckLookahead is set by a reorg so the next tick re-evaluates each lookahead epoch's // dependent_root instead of trusting its emitted marker.

The wrong drop we observed: the §5 duty-existence rule evaluated against a proposer duty view fetched before the receiver processed a just-added validator's registration — honest partials rejected with 'no duty for this epoch', quorum starved for that proposal slot (seen on the first §5-eligible epoch right after a registration wave; the stash/replay mechanism can't help since the message dies before the queue). Two complementary changes: Validation freshness: the duty store now tracks per-epoch staleness — the ProposerHandler marks the current and next epoch stale the moment an indices change arrives, and a completed refetch (Set) clears it. The §5 proposer-preferences and §6 self-build-envelope duty-existence checks treat a stale epoch like a not-yet-fetched one (skip, don't reject); data keeps being served to checks that must always enforce assignment. During such windows §5/§6 messages remain bounded by committee membership, the per-signer distinct-root cap and the per-epoch duty-count cap. Emission grace: the §5 handler defers (re-)emission for two slots after a validator-set change, so committee peers learn of the new validators (contract-event sync) and refresh their duty views before the one-shot partials are broadcast. Preferences target future slots, so the delay costs nothing; a pending reorg/fork recheck survives the grace and is consumed by the first post-grace tick. --- message/validation/common_checks.go | 17 ++++++--- message/validation/envelope_builder_test.go | 31 ++++++++++++++- .../validation/proposer_preferences_test.go | 15 ++++++-- operator/duties/dutystore/duties.go | 38 ++++++++++++++++++- operator/duties/dutystore/duties_test.go | 30 +++++++++++++++ operator/duties/proposer.go | 6 +++ operator/duties/proposer_preferences.go | 28 ++++++++++++-- operator/duties/proposer_preferences_test.go | 33 ++++++++++++++++ 8 files changed, 184 insertions(+), 14 deletions(-) diff --git a/message/validation/common_checks.go b/message/validation/common_checks.go index af1fa9df7a..d641b3cc72 100644 --- a/message/validation/common_checks.go +++ b/message/validation/common_checks.go @@ -198,21 +198,26 @@ func (mv *messageValidator) validateBeaconDuty( } // Rule: For a proposer-preferences message, require a real proposer assignment for the validator at - // the slot — but only once the slot's epoch is fetched.

The aggregation path re-derives the attestation-data root only when the cache of our own submitted root misses, and that cached root is the QBFT-decided value, so the decided payload-status index was never at risk on the common path. Make the fallback self-correcting instead: on Gloas a 404 under our beacon node's index retries under the flipped bit, the only other value the §2 index can hold. Both roots come from one fetch, so nothing else can differ. The retry is deliberately not applied on a cache hit, whose root is decided by construction — a 404 there is a real miss and must surface. The re-derivation also stops writing Index through the shared per-slot attestation-data cache pointer; that write-through was dead in practice (Electra+ beacon nodes already return Index=0) but live on the pre-Electra branch. V9 — telemetry gauging. PTC non-convergence now reports as its own no_quorum duty outcome rather than hiding inside the generic "likely stuck" every role shares. §3 has no consensus phase and already marks every other terminal path — abstain to not_required, beacon-node, signing or broadcast failure to failed — so a PTC duty still unmarked at the deadline can only be a convergence miss. The classification keys off the immutable runner role, so it stays race-free against the watcher goroutine. On the §6 side, add ssv.runner.envelope.build_match so reconstruction misses are countable: per operator an "other" share is expected, and the signal is cluster-wide — a decided envelope no operator matched means the builder's bytes were lost. V11 — Web3Signer fork_info on Gloas. No code change needed, but the reasoning is now recorded on GetForkInfo so it need not be re-derived: Web3Signer takes fork.current_version whenever epoch >= fork.epoch and hashes it into a ForkData root without consulting any milestone enum, so an unrecognized Gloas version still yields the correct domain. Its AttestationData schema also has no post-Electra index == 0 check, so the §2 payload-status index survives into the signing root. A live-instance confirm remains. Also unify the package's two 404-detection idioms behind one isNotFound helper covering both the typed go-eth2-client error and the httpStatusError the hand-rolled Gloas endpoints return. --- beacon/goclient/aggregator.go | 89 +++++++++---- beacon/goclient/aggregator_test.go | 119 +++++++++++++++++- beacon/goclient/errors.go | 18 +++ beacon/goclient/proposer_preferences.go | 4 +- observability/attributes.go | 4 + protocol/v2/ssv/runner/envelope.go | 4 +- protocol/v2/ssv/runner/observability.go | 21 ++++ protocol/v2/ssv/runner/runner.go | 19 ++- .../v2/ssv/runner/runner_deadline_test.go | 30 +++++ ssvsigner/ekm/remote_key_manager.go | 10 ++ 10 files changed, 289 insertions(+), 29 deletions(-) diff --git a/beacon/goclient/aggregator.go b/beacon/goclient/aggregator.go index 2784c8e21f..5de5d086b7 100644 --- a/beacon/goclient/aggregator.go +++ b/beacon/goclient/aggregator.go @@ -11,8 +11,10 @@ import ( "github.com/attestantio/go-eth2-client/spec/electra" "github.com/attestantio/go-eth2-client/spec/phase0" ssz "github.com/ferranbt/fastssz" + "go.uber.org/zap" "github.com/ssvlabs/ssv/networkconfig" + "github.com/ssvlabs/ssv/observability/log/fields" ) // IsAggregator returns true if the validator is selected as an aggregator for the given @@ -102,18 +104,25 @@ func (gc *GoClient) waitIntoSlot(ctx context.Context, slot phase0.Slot, interval } } -// computeAttestationDataRoot re-derives the attestation data root for the given slot/committee -// from this node's own view, used as a fallback when the cluster-attested root is unknown. +// computeAttestationDataRoot re-derives the attestation-data root for (slot, committeeIndex) from this +// node's own view.

Sub-quorum degrades silently to the enshrined flow — gossiped bids or self-build — and never blocks the proposal; reconstructions are counted, and the §4 build-source telemetry becomes a typed enum staged for the phase-2 reason split (no bid / economics / auth unavailable). Message validation admits the new type under RoleProposerPreferences with its own distinct-root budget and the §5 two-tier REJECT/IGNORE semantics; every other §5 wire rule (earliness, lateness, slot-advance exemption, assignment check, duty limit, fork gates) is role-scoped and applies unchanged. Config: the Builders YAML list (validated at startup) plumbs through ControllerOptions and CommonOptions — now built from a struct literal instead of the 17-argument constructor — to the runner options; documented in EXTERNAL_BUILDERS.md with the all-operators-identical requirement. Riding along: the remaining error-path domain sentinels join spectypes.DomainError. --- cli/operator/config.go | 6 + cli/operator/node.go | 1 + config/config.example.yaml | 15 ++ docs/EXTERNAL_BUILDERS.md | 45 +++- message/validation/const.go | 11 +- message/validation/partial_validation.go | 47 +++- message/validation/request_auth_test.go | 134 ++++++++++ message/validation/seen_msg_types.go | 7 +- message/validation/signer_state.go | 25 ++ operator/validator/controller.go | 45 ++-- protocol/v2/ssv/request_auth_cache.go | 64 +++++ protocol/v2/ssv/request_auth_cache_test.go | 37 +++ protocol/v2/ssv/runner/observability.go | 40 ++- protocol/v2/ssv/runner/proposer.go | 10 +- .../v2/ssv/runner/proposer_preferences.go | 243 +++++++++++++++-- .../ssv/runner/proposer_preferences_test.go | 2 +- protocol/v2/ssv/runner/ptc_attester.go | 2 +- protocol/v2/ssv/runner/request_auth_test.go | 249 ++++++++++++++++++ .../v2/ssv/runner/validator_registration.go | 2 +- protocol/v2/ssv/validator/opts.go | 51 +--- 20 files changed, 920 insertions(+), 116 deletions(-) create mode 100644 message/validation/request_auth_test.go create mode 100644 protocol/v2/ssv/request_auth_cache.go create mode 100644 protocol/v2/ssv/request_auth_cache_test.go create mode 100644 protocol/v2/ssv/runner/request_auth_test.go diff --git a/cli/operator/config.go b/cli/operator/config.go index 8c5e03e431..cde91f2651 100644 --- a/cli/operator/config.go +++ b/cli/operator/config.go @@ -15,6 +15,7 @@ import ( p2pv1 "github.com/ssvlabs/ssv/network/p2p" "github.com/ssvlabs/ssv/operator" operatorstorage "github.com/ssvlabs/ssv/operator/storage" + "github.com/ssvlabs/ssv/protocol/v2/types/gloas" "github.com/ssvlabs/ssv/storage/basedb" ) @@ -49,6 +50,7 @@ type config struct { ProposerDelay time.Duration `yaml:"ProposerDelay" env:"PROPOSER_DELAY" env-description:"Duration to wait out before requesting Ethereum block to propose if this Operator is proposer-duty Leader (eg. 300ms).

The cache also drops its redundant per-validator key — it is one instance per validator, like ProposedBlockRoots. A frozen request auth now carries every configured builder relationship behind its signing root: the root derives from (data, slot) alone, so distinct (URL, AuthData) entries sharing one pre-agreed token converge on one root and one reconstruction — previously last-write-wins left all but one of them silently unauthenticated. The single broadcast per root is unchanged. The request-auth distinct-root budget drops from entry cap + 4 to the entry cap exactly: the builder list is startup-only and auth roots are dependent_root-independent, so no in-window churn exists for headroom to cover — and wire validation being config-independent, every extra admitted root was pure surface for clusters that never opt in. Also: a runner-layer validator-index guard on auth partials (the auth root, unlike the §5 preference, doesn't bind the index); nodes with Builders configured and a remote signer now warn once at startup and disable the overlay locally instead of warning per builder per emission forever; GetSpecDir walks the module tree once; and a conciseness pass over the new surface's comments, deduplicating rationale to single homes. --- beacon/goclient/signing.go | 10 +- cli/operator/node.go | 7 ++ config/config.example.yaml | 4 +- docs/EXTERNAL_BUILDERS.md | 3 + ibft/storage/testutils.go | 20 ++- message/validation/const.go | 12 +- message/validation/partial_validation.go | 8 +- message/validation/signer_state.go | 5 +- operator/validator/controller.go | 8 +- protocol/v2/ssv/request_auth_cache.go | 63 +++++----- protocol/v2/ssv/request_auth_cache_test.go | 37 +++--- .../v2/ssv/runner/proposer_preferences.go | 114 +++++++++--------- protocol/v2/ssv/runner/request_auth_test.go | 25 ++-- protocol/v2/types/gloas/builder_entry.go | 40 +++--- protocol/v2/types/gloas/builder_entry_test.go | 12 +- 15 files changed, 185 insertions(+), 183 deletions(-) diff --git a/beacon/goclient/signing.go b/beacon/goclient/signing.go index 9b8b80d759..b63240e235 100644 --- a/beacon/goclient/signing.go +++ b/beacon/goclient/signing.go @@ -55,11 +55,11 @@ func (gc *GoClient) DomainData( ) (phase0.Domain, error) { switch domain { case spectypes.DomainApplicationBuilder, spectypes.DomainRequestAuth: - // Application-namespace domains are constructed from the connected network's genesis fork - // version with a zero genesis-validators root (compute_domain with defaults), never from a - // fork-versioned state: DomainApplicationBuilder (pre-Gloas validator registrations) and - // DomainRequestAuth (builder-specs' Gloas DOMAIN_REQUEST_AUTH, the direct-builder request - // auth — 0x0b000001, not the beacon DomainBeaconBuilder 0x0b000000). + // Application-namespace domains derive from the network's genesis fork version with a zero + // genesis-validators root (compute_domain with defaults), never from a fork-versioned + // state: DomainApplicationBuilder (pre-Gloas validator registrations) and DomainRequestAuth + // (the Gloas direct-builder request auth — 0x0b000001, not the beacon DomainBeaconBuilder + // 0x0b000000). var appDomain phase0.Domain forkData := phase0.ForkData{ CurrentVersion: gc.getBeaconConfig().GenesisForkVersion, diff --git a/cli/operator/node.go b/cli/operator/node.go index 24fae894c0..4647c92613 100644 --- a/cli/operator/node.go +++ b/cli/operator/node.go @@ -232,6 +232,13 @@ func newNode( ) (_ *node, err error) { usingSSVSigner := res.usingSSVSigner + if len(cfg.Builders) > 0 && usingSSVSigner { + // Web3Signer has no request-auth type, so this operator could never contribute an auth + // partial — warn once here instead of once per builder per emission in the runner. + logger.Warn("Builders configured with a remote signer: request-auth signing is unsupported there, disabling the direct-builder overlay on this operator (the cluster still reconstructs auths while at most f operators are remote-signing)") + cfg.Builders = nil + } + identity, err := resolveOperatorIdentity(ctx, logger, cfg, res) if err != nil { return nil, err diff --git a/config/config.example.yaml b/config/config.example.yaml index d794314d6b..6daeb67c70 100644 --- a/config/config.example.yaml +++ b/config/config.example.yaml @@ -63,7 +63,9 @@ OperatorPrivateKey: # ALL operators of every committee sharing a validator: AuthData (defaulting to the UTF-8 bytes of URL, # exactly as written) is threshold-signed, so any divergence silently disables that builder.

Preference partials replayed into a concluded duty bounce off the succeeded-gate harmlessly; the auth rounds have no such gate by design. Regression-tested (the new test fails on the old gate). A domain-fetch failure now freezes an empty root set, so peer auth partials hard-fail as unknown roots instead of burning queue retries — the dispatcher stash keeps them for replay should a re-emission freeze successfully. Also: a real AuthDataBytes error is logged instead of silently treated as the default entry; the URL-length check applies only when the URL's bytes are the auth data; the in-memory broadcast markers' restart re-broadcast cost is TODO'd for devnet gauging; message validation's per-type seen-root sets collapse into one seenRootSet type with a shared budget check; and the request-auth round moves to its own file beside the §5 dispatcher. --- message/validation/partial_validation.go | 80 ++++---- .../validation/proposer_preferences_test.go | 26 +-- message/validation/request_auth_test.go | 36 ++-- message/validation/signer_state.go | 51 +++-- .../v2/ssv/runner/proposer_preferences.go | 171 ++--------------- .../proposer_preferences_request_auth.go | 178 ++++++++++++++++++ protocol/v2/ssv/runner/request_auth_test.go | 113 +++++++++++ protocol/v2/types/gloas/builder_entry.go | 3 +- protocol/v2/types/gloas/builder_entry_test.go | 8 + 9 files changed, 406 insertions(+), 260 deletions(-) create mode 100644 protocol/v2/ssv/runner/proposer_preferences_request_auth.go diff --git a/message/validation/partial_validation.go b/message/validation/partial_validation.go index ba46519934..5c69eebdb4 100644 --- a/message/validation/partial_validation.go +++ b/message/validation/partial_validation.go @@ -301,43 +301,12 @@ func validatePartialSignatureMessageLimit( return e } case spectypes.ProposerPreferencesPartialSig: - // SIP #94 §5: admit up to maxProposerPreferencesDistinctRoots distinct signing roots per - // (slot, signer) — a dependent_root refresh re-emits under a new root — instead of the usual ≤1 - // pre-consensus cap.

19:54:21 +0300 Subject: [PATCH 128/228] gloas: reconcile the request-auth overlay to the merged Gloas builder specs builder-specs#165, beacon-APIs#630, and keymanager-APIs#88 merged, renaming the request-auth objects and reshaping the direct-builder config. Match them: - Rename the wire types RequestAuthV1/SignedRequestAuthV1 -> BuilderRequestAuth/ SignedBuilderRequestAuth and MaxRequestAuthDataSize -> MaxBuilderAuthDataSize (the spectypes DomainRequestAuth/RequestAuthPartialSig stay; the 0x0B000001 value is what matters), and regenerate the SSZ. Fix the domain doc comment: the signing domain is genesis-style, but the wire type is fork-versioned, so hops carrying the body set Eth-Consensus-Version. - Reshape the operator Builders config to keymanager-APIs#88's BuilderConfig: top-level MinBid/BuilderBoostFactor (p2p bids + per-entry defaults) wrapping an Entries list; drop MaxTrustedBid; PubKey -> BuilderPubKeys list; remove the empty-URL default entry (URLs now required); ValidateBuilderEntries -> ValidateBuilderConfig; add the #88 EffectiveMinBid/EffectiveBoostFactor resolution (consumed by the phase-2 produceBlockV4 POST). - Refresh config.example.yaml and docs/EXTERNAL_BUILDERS.md to the new shape and the merged spec references. Phase-1 reconcile for #2962; phases 2-3 (produceBlockV4 POST, submitBuilderPreferences) remain pending upstream consumption. --- cli/operator/config.go | 4 +- cli/operator/node.go | 4 +- config/config.example.yaml | 30 +-- docs/EXTERNAL_BUILDERS.md | 22 +- message/validation/const.go | 2 +- message/validation/request_auth_test.go | 2 +- message/validation/signer_state.go | 2 +- operator/validator/controller.go | 2 +- protocol/v2/ssv/request_auth_cache.go | 12 +- protocol/v2/ssv/request_auth_cache_test.go | 4 +- .../v2/ssv/runner/proposer_preferences.go | 20 +- .../proposer_preferences_request_auth.go | 25 +-- protocol/v2/ssv/runner/request_auth_test.go | 23 +- protocol/v2/ssv/validator/opts.go | 2 +- protocol/v2/types/gloas/builder_entry.go | 205 ++++++++++-------- protocol/v2/types/gloas/builder_entry_test.go | 115 +++++----- protocol/v2/types/gloas/request_auth.go | 51 ++--- .../v2/types/gloas/request_auth_encoding.go | 62 +++--- protocol/v2/types/gloas/request_auth_test.go | 54 ++--- ssvsigner/ekm/local_key_manager.go | 2 +- ssvsigner/ekm/remote_key_manager.go | 2 +- 21 files changed, 326 insertions(+), 319 deletions(-) diff --git a/cli/operator/config.go b/cli/operator/config.go index cde91f2651..2c6baa78fe 100644 --- a/cli/operator/config.go +++ b/cli/operator/config.go @@ -50,7 +50,7 @@ type config struct { ProposerDelay time.Duration `yaml:"ProposerDelay" env:"PROPOSER_DELAY" env-description:"Duration to wait out before requesting Ethereum block to propose if this Operator is proposer-duty Leader (eg. 300ms).

Our hand-rolled GET still used the old path form, so a spec-compliant beacon node 404s it and the PTC duty (SIP-94 §3) never submits. That 404 — not a missing CL endpoint — is what #2963 saw: the duties call keeps its epoch path param and succeeds, only the data call 404s. Reported in #3001. Point the constant at the query form, matching the sibling attestation_data call already in this package. Also handle the endpoint's 204 No Content, the spec's "no block seen for this slot" abstain signal: httpDo now returns the status code so requestPayloadAttestationData yields (nil, nil) on a 204 instead of failing to decode the empty body, and the runner treats nil data as the §3 abstain (markDutyNotRequired) rather than marking the duty failed. --- beacon/goclient/gloas_proposer.go | 3 +- beacon/goclient/ptc.go | 42 +++++++++++++++---------- beacon/goclient/ptc_test.go | 20 ++++++++++-- protocol/v2/blockchain/beacon/client.go | 3 +- protocol/v2/ssv/runner/ptc_attester.go | 8 ++--- 5 files changed, 51 insertions(+), 25 deletions(-) diff --git a/beacon/goclient/gloas_proposer.go b/beacon/goclient/gloas_proposer.go index d6b14bbf9e..84ea0f329e 100644 --- a/beacon/goclient/gloas_proposer.go +++ b/beacon/goclient/gloas_proposer.go @@ -198,7 +198,8 @@ func gloasHTTPDo(ctx context.Context, method, url string, body []byte, contentTy merged["Eth-Consensus-Version"] = consensusVersionGloas extraHeaders = merged } - return httpDo(ctx, gloasHTTPClient, method, url, body, "application/octet-stream", contentType, extraHeaders) + respBody, header, _, err := httpDo(ctx, gloasHTTPClient, method, url, body, "application/octet-stream", contentType, extraHeaders) + return respBody, header, err } // gloasOctetStreamHTTP issues an octet-stream (SSZ) request to a Gloas produce/publish endpoint and returns diff --git a/beacon/goclient/ptc.go b/beacon/goclient/ptc.go index 7b3dbad181..9c361440ef 100644 --- a/beacon/goclient/ptc.go +++ b/beacon/goclient/ptc.go @@ -21,8 +21,8 @@ import ( // yet, so these are issued as hand-rolled HTTP requests until it is rebased onto a Gloas-aware // release, at which point they become typed provider calls like the rest of GoClient. const ( - ptcDutiesPath = "/eth/v1/validator/duties/ptc/%d" // epoch - payloadAttestationDataPath = "/eth/v1/validator/payload_attestation_data/%d" // slot + ptcDutiesPath = "/eth/v1/validator/duties/ptc/%d" // epoch + payloadAttestationDataPath = "/eth/v1/validator/payload_attestation_data?slot=%d" // slot payloadAttestationsPath = "/eth/v1/beacon/pool/payload_attestations" // consensusVersionGloas is the Eth-Consensus-Version header value for Gloas payload attestations. @@ -44,7 +44,7 @@ func (gc *GoClient) PayloadAttestationDuties(ctx context.Context, epoch phase0.E } // PayloadAttestationData returns the PayloadAttestationData to attest to for the slot, from the -// first beacon client that responds. +// first beacon client that responds, or (nil, nil) if the node reports no block for the slot (204). func (gc *GoClient) PayloadAttestationData(ctx context.Context, slot phase0.Slot) (*gloas.PayloadAttestationData, error) { return firstClientResult(ctx, gc, "PayloadAttestationData", http.MethodGet, func(ctx context.Context, addr string) (*gloas.PayloadAttestationData, error) { return requestPayloadAttestationData(ctx, gloasHTTPClient, addr, slot) @@ -103,13 +103,22 @@ func requestPTCDuties(ctx context.Context, httpClient *http.Client, addr string, return resp.Data, nil } -// requestPayloadAttestationData GETs the PayloadAttestationData the PTC member must attest to for the slot. +// requestPayloadAttestationData GETs the PayloadAttestationData for the slot.

That head splits the generic spectypes.NewMsgID(domain, []byte, role) into the fixed-size spectypes.NewValidatorMsgID / spectypes.NewCommitteeMsgID. Migrate all production call sites to the typed constructors — output is byte-identical, so message ids stay wire-compatible: validator-keyed runners use NewValidatorMsgID, committee-keyed ones NewCommitteeMsgID, and the generic []byte identifier resolver picks by executor length. Tests build synthetic and intentionally-malformed ids from arbitrary-length executor bytes, which the fixed-size constructors cannot express, so add protocol/v2/types/ssvtestingutils.NewMsgID — a test-only reproduction of the removed constructor — and repoint the test call sites at it. Also: - type the []byte validator-pubkey params of the signAndBroadcast* and dutyDataToSSVMsg helpers as spectypes.ValidatorPK, dropping [:] at callers; - build the identifier directly per switch case in the testing runner helper; - go mod tidy: prune stale ssv-spec go.sum entries and mark golang.org/x/exp (imported directly by the ssv spectest helpers) as a direct dependency. --- .../dutytracer/collector_aggregator_test.go | 7 +- exporter/dutytracer/collector_quorum_test.go | 13 +-- exporter/dutytracer/collector_test.go | 25 +++--- exporter/traces/model_encoding_test.go | 10 ++- go.mod | 4 +- go.sum | 10 +-- .../validation/consensus_validation_test.go | 5 +- message/validation/envelope_proposer_test.go | 3 +- message/validation/logger_fields_test.go | 3 +- .../validation/proposer_preferences_test.go | 3 +- message/validation/ptc_attester_test.go | 3 +- message/validation/signed_ssv_message_test.go | 5 +- message/validation/validation_test.go | 85 ++++++++++--------- network/p2p/p2p_test.go | 5 +- network/topics/controller_test.go | 3 +- network/topics/msg_validator_test.go | 3 +- operator/validator/controller.go | 10 ++- operator/validator/controller_bench_test.go | 3 +- operator/validator/controller_test.go | 11 +-- operator/validator/identifier_fn_test.go | 5 +- operator/validator/router_test.go | 9 +- .../qbft/controller/controller_fork_test.go | 19 +++-- .../v2/queue/worker/message_worker_test.go | 7 +- .../v2/ssv/queue/message_prioritizer_test.go | 5 +- protocol/v2/ssv/runner/aggregator.go | 4 +- .../v2/ssv/runner/aggregator_committee.go | 8 +- ...gator_postconsensus_classification_test.go | 3 +- protocol/v2/ssv/runner/committee.go | 4 +- protocol/v2/ssv/runner/envelope.go | 2 +- protocol/v2/ssv/runner/envelope_e2e_test.go | 5 +- .../v2/ssv/runner/preconsensus_domain_test.go | 8 +- protocol/v2/ssv/runner/proposer.go | 4 +- .../v2/ssv/runner/proposer_preferences.go | 2 +- .../proposer_preferences_request_auth.go | 2 +- protocol/v2/ssv/runner/proposer_test.go | 5 +- protocol/v2/ssv/runner/ptc_attester.go | 2 +- protocol/v2/ssv/runner/runner.go | 8 +- .../ssv/runner/sync_committee_contribution.go | 4 +- ...tee_contribution_preconsensus_flow_test.go | 3 +- .../v2/ssv/runner/validator_registration.go | 2 +- protocol/v2/ssv/runner/voluntary_exit.go | 2 +- protocol/v2/ssv/testing/runner.go | 13 +-- protocol/v2/ssv/validator/committee.go | 2 +- .../ssv/validator/committee_observer_test.go | 3 +- protocol/v2/ssv/validator/duty_executor.go | 6 +- protocol/v2/ssv/validator/startup.go | 2 +- protocol/v2/ssv/validator/validator.go | 2 +- .../v2/types/ssvtestingutils/message_id.go | 30 +++++++ ssvsigner/go.mod | 2 +- ssvsigner/go.sum | 8 +- 50 files changed, 221 insertions(+), 171 deletions(-) create mode 100644 protocol/v2/types/ssvtestingutils/message_id.go diff --git a/exporter/dutytracer/collector_aggregator_test.go b/exporter/dutytracer/collector_aggregator_test.go index 43b1f145c7..98cd38d9a6 100644 --- a/exporter/dutytracer/collector_aggregator_test.go +++ b/exporter/dutytracer/collector_aggregator_test.go @@ -16,6 +16,7 @@ import ( "github.com/ssvlabs/ssv/networkconfig" ssvtypes "github.com/ssvlabs/ssv/protocol/v2/types" + "github.com/ssvlabs/ssv/protocol/v2/types/ssvtestingutils" "github.com/ssvlabs/ssv/registry/storage" registrystoragemocks "github.com/ssvlabs/ssv/registry/storage/mocks" ) @@ -192,7 +193,7 @@ func TestCollector_AggregatorCommitteeDuty_PostConsensusQuorum(t *testing.T) { operator4 = spectypes.OperatorID(4) ) -

Neither path can exist under the Go module cache, so TestQBFTMapping/TestSSVMapping died generating vectors and the alan variants failed all 110 msg-processing state comparisons (the alan pin still ships vectors in-module, but the new resolver looks beside the module root instead). Teach the harness both layouts: - GenerateSpecTestJSON runs the split-layout generator from a scaffold dir carrying a go.mod inside the artifact cache, so it writes to /spec-tests/; the generated state_comparison vectors are kept for the per-test overrides, and the cached-tests fast path applies only while those vectors are still available. - New storage helpers (StateComparisonDir / ReadStateComparisonFile / UnmarshalStateComparison) resolve the state-comparison vectors in-module for pre-split pins (alan) and from the artifact scaffold for split pins, regenerating on a cold cache. All spectest call sites are repointed at them, replacing the spec's own resolver, which hardcodes the sibling-checkout paths. --- ibft/storage/testutils.go | 115 +++++++++++++++--- protocol/v2/qbft/spectest/controller_type.go | 17 +-- .../v2/qbft/spectest/msg_processing_type.go | 12 +- .../spectest/committee_msg_processing_type.go | 22 ++-- .../sync_committee_aggregator_proof_type.go | 9 +- protocol/v2/ssv/spectest/util.go | 9 +- 6 files changed, 125 insertions(+), 59 deletions(-) diff --git a/ibft/storage/testutils.go b/ibft/storage/testutils.go index d6f37d5c5b..dec2f6e159 100644 --- a/ibft/storage/testutils.go +++ b/ibft/storage/testutils.go @@ -14,11 +14,13 @@ import ( "strings" "testing" + "golang.org/x/mod/modfile" + "golang.org/x/mod/module" + specqbft "github.com/ssvlabs/ssv-spec/qbft" spectypes "github.com/ssvlabs/ssv-spec/types" "github.com/ssvlabs/ssv-spec/types/testingutils" - "golang.org/x/mod/modfile" - "golang.org/x/mod/module" + typescomparable "github.com/ssvlabs/ssv-spec/types/testingutils/comparable" "github.com/ssvlabs/ssv/ssvsigner/keys/rsaencryption" ) @@ -119,21 +121,29 @@ func GenerateSpecTestJSON(path string, module string) ([]byte, error) { return nil, fmt.Errorf("failed to create spec artifacts directory: %w", err) } testJSONPath := filepath.Join(artifactDir, "tests.json") + scaffoldOut := filepath.Join(artifactDir, "spec-tests", module) - // Fast path: use already-generated tests.json from the local artifact cache. + // Fast path: use already-generated tests.json from the local artifact cache, provided the + // state-comparison vectors the per-test overrides read later are also available (in-module for + // pre-split spec versions, or previously regenerated into the artifact scaffold). // #nosec G304 -- test helper reads from a controlled cache path. jsonBytes, err := os.ReadFile(testJSONPath) - if err == nil && len(jsonBytes) > 0 { + if err == nil && len(jsonBytes) > 0 && (pathExists(filepath.Join(p, "state_comparison")) || pathExists(filepath.Join(scaffoldOut, "state_comparison"))) { return jsonBytes, nil } - // Fast path for first CI run: build tests.json from pre-generated files in ssv-spec module. + // Fast path for pre-split spec versions (e.g. the alan pin): build tests.json from the + // pre-generated files the ssv-spec module ships in-module. jsonBytes, err = buildTestsJSONFromDir(filepath.Join(p, "tests")) if err == nil { _ = os.WriteFile(testJSONPath, jsonBytes, 0600) return jsonBytes, nil } + // Split layout: newer ssv-spec versions ship no generated vectors in-module (they moved to the + // sibling ssvlabs/spec-tests repo, which a module-cache checkout cannot host), so build and run + // the module's generator to produce them locally. + // Step 2: Build the Go package, outputting an executable to the artifact directory. binaryPath := filepath.Join(artifactDir, module) //nolint: gosec @@ -144,31 +154,108 @@ func GenerateSpecTestJSON(path string, module string) ([]byte, error) { return nil, fmt.Errorf("go build failed: %w; output: %s", err, buildOutput) } - // Step 3: Execute the built binary. - // It is assumed that running the binary generates tests.json in artifactDir. + // Step 3: Execute the built binary.

Wire what the node can genuinely run today and skip the rest explicitly: - The Gloas valcheck vectors run against the node's real checkers: NewGloasVoteChecker is selected for Gloas-era committee vectors by the spec's testing fork epoch (mirroring the committee runner's slot-keyed selection), the proposer checker gets a Gloas-scheduled beacon config, and NewEnvelopeChecker runs over the spec's seeded §4-root store. - Two node fixes those vectors flushed out: the §6 envelope value check now pins the wire-carried duty's beacon role (slot/index/pubkey were already pinned), and the validator-registration runner gains the runner-side Gloas deprecation guard matching ssv-spec's (the scheduler drain and the wire rejection already existed). The guard is covered by a node unit test, since the spec's own vector for it cannot run yet (below). - The Gloas checkers' error codes are aligned with the spec's new dedicated codes (DecodeGloasBeaconVote, the Envelope* family). - The unmapped Gloas vectors are skipped under one documented reason: the new runner roles (the node's implementations deliberately differ in internals) and the Gloas-era variants of shared vectors (their post-state roots embed the network config, which the ssvtesting constructors cannot schedule Gloas into without diverging those roots; the testing beacon-node wrapper also has no Gloas produce surface). Also skipped: the new different-slots aggregator-committee vector, whose expected post-state records the runner before the failing duty validation, where the node validates first. Together with the split-layout support this turns the PR's spec-test CI green; mapping the skipped vectors onto the node is tracked as a repin follow-up. --- .../v2/ssv/runner/validator_registration.go | 11 +- .../ssv/runner/validator_registration_test.go | 32 +++++ protocol/v2/ssv/spectest/helpers.go | 17 ++- protocol/v2/ssv/spectest/ssv_mapping_test.go | 125 +++++++++++++++++- protocol/v2/ssv/spectest/value_checker.go | 37 +++++- protocol/v2/ssv/value_check.go | 21 ++- 6 files changed, 227 insertions(+), 16 deletions(-) diff --git a/protocol/v2/ssv/runner/validator_registration.go b/protocol/v2/ssv/runner/validator_registration.go index fe5db86947..f632645522 100644 --- a/protocol/v2/ssv/runner/validator_registration.go +++ b/protocol/v2/ssv/runner/validator_registration.go @@ -15,10 +15,11 @@ import ( "github.com/attestantio/go-eth2-client/spec/phase0" "github.com/cespare/xxhash/v2" ssz "github.com/ferranbt/fastssz" - spectypes "github.com/ssvlabs/ssv-spec/types" "go.opentelemetry.io/otel/trace" "go.uber.org/zap" + spectypes "github.com/ssvlabs/ssv-spec/types" + "github.com/ssvlabs/ssv/ssvsigner/ekm" "github.com/ssvlabs/ssv/networkconfig" @@ -195,6 +196,14 @@ func (r *ValidatorRegistrationRunner) executeDuty(ctx context.Context, logger *z return err } + // From Gloas the validator registration duty is deprecated: fee recipient and gas limit travel + // in the §5 proposer preferences instead (SIP #94 §5).

Also realign the two go-ethereum source permalinks in network/discovery/shared_conn.go to v1.17.5 (the cited lines and the size 100 are unchanged there). --- go.mod | 89 ++++++------ go.sum | 226

source beacon-chain types from go-eth2-client; SSZ via dynamic-ssz MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit protocol/v2/types/gloas now aliases go-eth2-client's spec/gloas for the Gloas (ePBS) beacon-chain containers — the canonical, progressive-SSZ-correct types — instead of hand-rolling them (~4k fewer lines). Only SSV-owned types remain: the consensus values (GloasBeaconVote, EnvelopeConsensusData, the blinded envelope) and the node types ssv-spec lacks (builder config/entry, PTC duty, builder request auth), with encoders now generated by pk910/dynamic-ssz — fastssz cannot merkleize the progressive containers/lists. go-eth2-client's move to dynamic-ssz drops fastssz's HashRoot (GetTree), so ssz.HashRoot becomes the narrow spectypes.HashRoot across the runner package, consensus_data.go, and ssvsigner; go-bitfield switches to OffchainLabs where go-eth2-client types are composed. BlockSlot()/Blinded() become free functions, and ssvsigner's block-signing path type-switches on *gloas.BeaconBlock directly, dropping the structural slashableBeaconBlock interface. Drop the SSZ round-trip/JSON tests of the now-aliased types (go-eth2-client and ssv-spec's dynssz parity suite own that coverage). Repin ssv-spec, eth2-key-manager, and the go-eth2-client fork in both modules. --- beacon/goclient/aggregator_test.go | 2 +- beacon/goclient/signing.go | 4 +- go.mod | 12 +- go.sum | 26 +-

envelope round timers, voter join, reorg gating (review follow-ups) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address the review findings on the ePBS branch. - roundtimer: the §6 envelope proposer gets the proposer's round-relative timeouts. It fell into the slot-anchored branch with a zero head start, so round 1 expired the moment the instance started whenever the §4 block published later than QuickTimeout into the slot, and with the envelope round cap of 2 peers then rejected the round. RoundRelativeRole is the one predicate the timer and message validation's round-spread exemption now share, so the two cannot drift apart again. - §6: an operator whose beacon node cannot produce the envelope (every non-builder on a cluster whose operators run separate beacon nodes) joins the QBFT instance as a voter instead of failing the duty before the instance exists, which left the round short of a quorum. Controller.JoinInstance starts the instance without a value; a leader with an empty start value skips its round-1 proposal rather than broadcast an empty one; a later round it leads re-proposes only an already-prepared value, since the justification's value check rejects an empty one. The round still relies on the builder leading round 1, which holds whenever §4 decided in round 1. - duties/proposer: a reorg refetches the current epoch only when the current dependent root changed, as its comment already said. The unconditional refetch raced the idle-time indices-change case and made TestScheduler_Proposer_Reorg_Previous_Indices_Changed flaky. - §5: a partial for a proposal slot with no local sub-runner is a plain error; the dispatcher stash replays it on duty start, so a queue retry only churned. - proposer: reset the Gloas produce markers per duty so a stale owner-match cannot echo a previous slot's Eth-Builder-Url, and treat a produced block that fails to hash as an error.

Bump the semconv import v1.37.0 -> v1.39.0 across all in-tree users (v1.39.0 already ships in otel@v1.41.0, so no go.mod change). Only resources.go triggered the crash; the other files are metric-name-only and their attribute keys are value-identical between 1.37 and 1.39, so emitted metrics are unchanged. Also note the version-alignment requirement on the import and fix an "OTeL" typo.

Add it to the goclient aggregate conversions, the consensus-data decode, and a signed-aggregate constructor now shared by both aggregator runners; the remote signer rejects Gloas aggregates explicitly (#3000). Drop ForkAtEpoch's Fulu cap in the node and ssvsigner: a scheduled Gloas fork resolves from its epoch on and absent forks are skipped, so attestations ride gloas.Attestation and the aggregator-committee consensus data stamps DataVersionGloas (SIP #94 §2, #2998). This needs ssv-spec's Gloas arms to build the Gloas containers, so both go.mods repin to the ssv-spec dynssz branch head that carries them (ssvlabs/ssv-spec#643). The remote signer's fork_info substitution is no longer needed. Pin the Gloas roots to the chain (#3008): a devnet-8 finalized block whose HashTreeRoot must equal the chain's header root and whose proposer signature must verify, plus its execution-payload envelope, which must blind to the full envelope's root. EIP-7688/7916 change only merkleization, so round-trip tests alone cannot catch a wrong root. --- beacon/goclient/aggregator.go | 87 +++--------- beacon/goclient/aggregator_gloas_test.go | 78 +++++++++++ beacon/goclient/aggregator_test.go | 2 + go.mod | 2 +- go.sum | 4 +- networkconfig/beacon.go | 40 +++--- networkconfig/beacon_test.go | 57 ++++++++ protocol/v2/ssv/runner/aggregator.go | 39 +++++- .../v2/ssv/runner/aggregator_committee.go | 61 +-------- .../ssv/runner/aggregator_versioned_test.go | 69 ++++++++++ protocol/v2/types/consensus_data.go | 9 ++ protocol/v2/types/consensus_data_test.go | 72 ++++++++++ .../types/gloas/beacon_block_golden_test.go | 125 ++++++++++++++++++ .../testdata/devnet8_gloas_block_144352.ssz | Bin 0 -> 2142 bytes .../devnet8_gloas_envelope_144352.ssz | Bin 0 -> 137748 bytes ssvsigner/ekm/remote_key_manager.go | 32 ++--- ssvsigner/ekm/remote_key_manager_test.go | 12 +- ssvsigner/go.mod | 2 +- ssvsigner/go.sum | 4 +- ssvsigner/internal/beaconcfg/config.go | 8 +- ssvsigner/internal/beaconcfg/config_test.go | 29 ++++ 21 files changed, 554 insertions(+), 178 deletions(-) create mode 100644 beacon/goclient/aggregator_gloas_test.go create mode 100644 protocol/v2/ssv/runner/aggregator_versioned_test.go create mode 100644 protocol/v2/types/consensus_data_test.go create mode 100644 protocol/v2/types/gloas/beacon_block_golden_test.go create mode 100644 protocol/v2/types/gloas/testdata/devnet8_gloas_block_144352.ssz create mode 100644 protocol/v2/types/gloas/testdata/devnet8_gloas_envelope_144352.ssz diff --git a/beacon/goclient/aggregator.go b/beacon/goclient/aggregator.go index 5de5d086b7..a35f1d50d4 100644 --- a/beacon/goclient/aggregator.go +++ b/beacon/goclient/aggregator.go @@ -9,6 +9,7 @@ import ( "github.com/attestantio/go-eth2-client/api" "github.com/attestantio/go-eth2-client/spec" "github.com/attestantio/go-eth2-client/spec/electra" + eth2gloas "github.com/attestantio/go-eth2-client/spec/gloas" "github.com/attestantio/go-eth2-client/spec/phase0" ssz "github.com/ferranbt/fastssz" "go.uber.org/zap" @@ -233,6 +234,7 @@ func (gc *GoClient) fetchAggregate( return resp, err } +// versionedAggregateToSSZ unwraps the fetched aggregate into its fork's attestation container. func versionedAggregateToSSZ(va *spec.VersionedAttestation) (ssz.Marshaler, spec.DataVersion, error) { switch va.Version { case spec.DataVersionPhase0: @@ -270,81 +272,36 @@ func versionedAggregateToSSZ(va *spec.VersionedAttestation) (ssz.Marshaler, spec return nil, DataVersionNil, errMultiClient(fmt.Errorf("aggregate attestation %s data is nil", va.Version.String()), "AggregateAttestation") } return va.Fulu, va.Version, nil + case spec.DataVersionGloas: + if va.Gloas == nil { + return nil, DataVersionNil, errMultiClient(fmt.Errorf("aggregate attestation %s data is nil", va.Version.String()), "AggregateAttestation") + } + return va.Gloas, va.Version, nil default: return nil, DataVersionNil, errMultiClient(fmt.Errorf("unknown data version: %d", va.Version), "AggregateAttestation") } } +// versionedToAggregateAndProof wraps the fetched aggregate into its fork's AggregateAndProof.

It also kept a look-ahead answer for good, although beacon nodes have been seen to shift assignments between the look-ahead and the epoch itself. The look-ahead now runs in the pre-fork epoch too, in the tick loop and at startup. An epoch filled by a look-ahead is re-fetched at its first tick, bounded by the slot's cutoff, and the settled answer replaces the cached one before the slot is scheduled; on failure the cached view stays in use and the next tick retries. All fetches are now bounded by the slot, so a hung beacon node cannot stall the loop. PayloadAttestationDuties returns the response's dependent_root, so the reconcile log tells a reorg's change (info) from the beacon node's own (warning). Reorg events drop only the epoch whose dependent root changed, as the attester handler does; an indices change still clears everything.

Nothing re-sends them, so a transient clock error on the sender's slot tick cost the whole duty; on a devnet it cost a block. Attestations survive the same blip only because QBFT round changes recover for them. Add an early margin of one second on top of the clock tolerance for every role, the early-side counterpart of the late margin. Accepting early loses nothing: the validator queue pops only duty-start events while no duty runs, the committee keeps a per-slot queue whose consumer starts with the duty, and a runner still on the previous slot returns a future-slot partial as retryable, so the message simply waits for the local slot tick. Proposer preferences keep their lookahead window on top.

Binds leaves PayloadRoot unpinned: validation admits one dissemination from any committee operator, so a faulty one can race a differing PayloadRoot in and split the envelope signing round, costing the reveal. Recorded at the binding as an accepted liveness-only gap, with the mitigation under discussion on SIP #94: commit the payload root in the §4 value, which also retires dissemination. The duty-count ring now spans three epochs for the roles whose lateness TTL is an epoch plus LateSlotAllowance (committee, aggregator committee, aggregator): near a boundary their acceptable slots reach two epochs back, and with a ring of two the oldest epoch shared its entry with the newest and had its count evicted, re-opening its limit. The comment claiming at most one epoch boundary was wrong. The envelope runner's single-slot assumption is stated at the reset: an envelope is due by half the slot and a stale dissemination is dropped, so back-to-back self-build proposals never overlap. The PTC reorg log now matches the other duty handlers at Info. The "joining as a voter" branch in instance.Start is removed: with JoinInstance gone, every value checker rejects an empty value before an instance exists, so the branch was dead. The field doc and the tests that described the removed flow are updated; the round-change test now gives the leader its own start value and checks the prepared value wins over it. --- .../validation/proposer_preferences_test.go | 13 +++-- message/validation/validation.go | 13 +++-- operator/duties/ptc_attestation.go | 2 +- protocol/v2/qbft/instance/instance.go | 15 +----- protocol/v2/qbft/instance/start_test.go | 53 ++++--------------- protocol/v2/ssv/proposed_blocks.go | 7 ++- protocol/v2/ssv/runner/envelope.go | 4 +- 7 files changed, 38 insertions(+), 69 deletions(-) diff --git a/message/validation/proposer_preferences_test.go b/message/validation/proposer_preferences_test.go index 8b21511cf5..ef906e2e85 100644 --- a/message/validation/proposer_preferences_test.go +++ b/message/validation/proposer_preferences_test.go @@ -15,6 +15,7 @@ import ( "github.com/ssvlabs/ssv/networkconfig" "github.com/ssvlabs/ssv/operator/duties/dutystore" + ssvtypes "github.com/ssvlabs/ssv/protocol/v2/types" "github.com/ssvlabs/ssv/protocol/v2/types/ssvtestingutils" ) @@ -50,13 +51,17 @@ func TestStoredSlotCount_ProposerPreferences(t *testing.T) { mv.storedSlotCount(spectypes.RoleProposerPreferences)) } -// Proposer preferences keep duty counts for the four epochs their acceptable slots span at once -// (SIP #94 §7); every other role keeps the current and previous epoch. +// The duty-count ring spans every epoch a role's lateness window can still accept (SIP #94 §7): the +// proposer lookahead for preferences, three epochs for the roles with the epoch-long TTL, two for the rest. func TestStoredEpochCount(t *testing.T) { mv := &messageValidator{netCfg: networkconfig.TestNetwork} require.Equal(t, uint64(4), mv.storedEpochCount(spectypes.RoleProposerPreferences)) - require.Equal(t, uint64(2), mv.storedEpochCount(spectypes.RoleProposer)) - require.Equal(t, uint64(2), mv.storedEpochCount(spectypes.RoleCommittee)) + for _, role := range []spectypes.RunnerRole{spectypes.RoleCommittee, spectypes.RoleAggregatorCommittee, ssvtypes.RoleAggregator} { + require.Equal(t, uint64(3), mv.storedEpochCount(role), role.String()) + } + for _, role := range []spectypes.RunnerRole{spectypes.RoleProposer, ssvtypes.RoleSyncCommitteeContribution, spectypes.RolePTCAttester} { + require.Equal(t, uint64(2), mv.storedEpochCount(role), role.String()) + } } // The per-epoch duty limit must count each epoch on its own when a lookahead epoch's preferences arrive diff --git a/message/validation/validation.go b/message/validation/validation.go index 43340df76a..8d418e8a7f 100644 --- a/message/validation/validation.go +++ b/message/validation/validation.go @@ -435,11 +435,16 @@ func (mv *messageValidator) storedSlotCount(role spectypes.RunnerRole) uint64 { // long as any message they gate is acceptable (SIP #94 §7).

The same duty therefore logged under two duty_id values, and a search on one silently missed the message-validation lines — the ones that say why a message was refused. Proposer, validator registration, voluntary exit, PTC attester, proposer preferences and envelope proposer were affected. Use the shared builder in both branches. The test pins the exact regression with the issue's example and sweeps every per-validator role for the shared form; the formatter tests gain the three Gloas roles their lockstep list claimed to cover.

The data is slot-level, so a node with N PTC members in a slot fired N identical requests at the PTC cutoff; on a large local testnet one slow moment produced 69 requests and 69 failures for a single slot. The attestation-data path already collapses such bursts. Mirror it: a per-slot singleflight joins the concurrent fetches into one request, whose result is cached for the slot's later callers so every PTC member of this node signs the same observation. The abstain signal (nil, the beacon node's 204) is not cached, since a block may still arrive, and neither is a failure. The leader's context is detached as on the attestation path, so one caller's cancellation cannot fail the others. The attestation-data doc no longer claims a deep copy it never made.

The per-duty reset moved from StartNewDuty into executeDuty, which runs only once the duty passed the start guard, so a rejected duplicate start no longer wipes an in-flight slot. The before-selection retry is scoped to the running slot, so a stale partial is dropped by the slot check instead of being replayed until the retry budget runs out. The reveal data is released when the duty concludes: the runner takes it over from the proposed-blocks store, which drops its own reference, so the blobs live in one place and go with the slot rather than with the validator's next self-build proposal. Validation: the per-peer dissemination record nothing read is gone — a repeat is ignored whichever peer relays it — and the verdict tests gain the slot-regression rule and a full epoch of one-per-slot disseminations, the most the duty-count cap can ever see. Comments record the carrier's size bound at disseminate, the early margin's side effect on monotonic-slot roles where the constant lives, and the deliberate repeat of the one-signer rule in the validator dispatch. --- message/validation/const.go | 6 +- message/validation/envelope_dissemination.go | 11 ++-- .../validation/envelope_dissemination_test.go | 15 +++++ protocol/v2/ssv/proposed_blocks.go | 19 +++++- protocol/v2/ssv/proposed_blocks_test.go | 11 ++++ protocol/v2/ssv/runner/envelope.go | 52 +++++++++++----- protocol/v2/ssv/runner/envelope_test.go | 62 +++++++++++++++++++ protocol/v2/ssv/validator/validator.go | 2 + 8 files changed, 156 insertions(+), 22 deletions(-) diff --git a/message/validation/const.go b/message/validation/const.go index c995ef3a43..9420158d9f 100644 --- a/message/validation/const.go +++ b/message/validation/const.go @@ -32,7 +32,11 @@ const ( // it back as retryable.

A finished duty keeps accepting the slot's post-consensus packets until the envelope reconstructs (awaitingEnvelope, bounded to the slot), with the queue consumer delivering them through PostConsensusAwaiter while holding everything else for the next duty. - Runner interface: expectedPostConsensusRootsAndDomains returns roots with their own domain and optionality; verifyExpectedPostConsensusRoots mirrors the spec (count bound, unexpected root, missing required root). - Value check: Version pinned to the slot's fork, payload_root zero iff not self-build, spec error codes for the Gloas rules. - Message validation: the Gloas proposer's post-consensus packet may carry two entries; the role 9, EnvelopePartialSig and dissemination rules are gone. - Removed the envelope runner, the proposed-blocks store, the dissemination validator and every reference to the dropped role and message type. --- exporter/dutytracer/collector.go | 2 +- exporter/dutytracer/collector_test.go | 1 - go.mod | 2 +- go.sum | 4 +- message/validation/common_checks.go | 21 +- message/validation/common_checks_test.go | 2 +- message/validation/consensus_validation.go | 3 +- message/validation/envelope_dissemination.go | 147 ----- .../validation/envelope_dissemination_test.go | 210 ------- message/validation/envelope_proposer_test.go | 98 --- message/validation/errors.go | 3 - message/validation/logger_fields_test.go | 2 +- message/validation/partial_validation.go | 28 +- message/validation/proposer_gloas_test.go | 32 + message/validation/seen_msg_types.go | 2 +- message/validation/signed_ssv_message.go | 7 +- message/validation/signed_ssv_message_test.go | 5 +- message/validation/signer_state.go | 6 - message/validation/validation.go | 7 - network/p2p/p2p_pubsub.go | 9 +- network/p2p/p2p_pubsub_test.go | 31 - observability/attributes.go | 2 - observability/utils/format_test.go | 6 - operator/validator/controller.go | 30 +- operator/validator/controller_test.go | 5 +- protocol/v2/message/msg.go | 7 - protocol/v2/message/msg_test.go | 2 - protocol/v2/qbft/roundtimer/timer_test.go | 1 - protocol/v2/ssv/proposed_blocks.go | 103 ---- protocol/v2/ssv/proposed_blocks_test.go | 89 --- protocol/v2/ssv/queue/messages.go | 27 +- protocol/v2/ssv/request_auth_cache.go | 4 +- protocol/v2/ssv/runner/aggregator.go | 12 +- .../v2/ssv/runner/aggregator_committee.go | 8 +- protocol/v2/ssv/runner/committee.go | 6 +- protocol/v2/ssv/runner/envelope.go | 441 -------------- protocol/v2/ssv/runner/envelope_test.go | 497 --------------- protocol/v2/ssv/runner/observability.go | 10 +- protocol/v2/ssv/runner/proposer.go | 450 +++++++++----- .../v2/ssv/runner/proposer_preferences.go | 10 +- protocol/v2/ssv/runner/proposer_test.go | 564 +++++++++++++----- protocol/v2/ssv/runner/ptc_attester.go | 4 +- protocol/v2/ssv/runner/runner.go | 32 +- protocol/v2/ssv/runner/runner_validations.go | 83 ++- .../ssv/runner/sync_committee_contribution.go | 12 +- .../v2/ssv/runner/validator_registration.go | 6 +- protocol/v2/ssv/runner/voluntary_exit.go | 6 +- protocol/v2/ssv/spectest/ssv_mapping_test.go | 4 +- protocol/v2/ssv/validator/msg_queue.go | 25 +- protocol/v2/ssv/validator/queue_validator.go | 30 +- .../v2/ssv/validator/queue_validator_test.go | 49 +- protocol/v2/ssv/validator/validator.go | 24 - protocol/v2/ssv/value_check.go | 48 +- protocol/v2/ssv/value_check_test.go | 70 ++- .../types/gloas/beacon_block_golden_test.go | 9 +- .../gloas/execution_payload_envelope_test.go | 18 +- protocol/v2/types/gloas/generate.yaml | 2 + .../v2/types/gloas/gloasproposaldata_ssz.go | 121 ++++ protocol/v2/types/gloas/proposal_data.go | 58 ++ protocol/v2/types/gloas/proposal_data_test.go | 79 +++ protocol/v2/types/gloas/spec_aliases.go | 72 +-- protocol/v2/types/gloas/testing.go | 19 +- 62 files changed, 1378 insertions(+), 2289 deletions(-) delete mode 100644 message/validation/envelope_dissemination.go delete mode 100644 message/validation/envelope_dissemination_test.go delete mode 100644 message/validation/envelope_proposer_test.go create mode 100644 message/validation/proposer_gloas_test.go delete mode 100644 protocol/v2/ssv/proposed_blocks.go delete mode 100644 protocol/v2/ssv/proposed_blocks_test.go delete mode 100644 protocol/v2/ssv/runner/envelope.go delete mode 100644 protocol/v2/ssv/runner/envelope_test.go create mode 100644 protocol/v2/types/gloas/gloasproposaldata_ssz.go create mode 100644 protocol/v2/types/gloas/proposal_data.go create mode 100644 protocol/v2/types/gloas/proposal_data_test.go diff --git a/exporter/dutytracer/collector.go b/exporter/dutytracer/collector.go index 9d9096be35..bc113e71cf 100644 --- a/exporter/dutytracer/collector.go +++ b/exporter/dutytracer/collector.go @@ -873,7 +873,7 @@ func (c *Collector) collect(ctx context.Context, msg *queue.SSVMessage, verifySi // explicitly instead of erroring per message in toBNRole now that message validation admits // the roles on the wire (issue #2999).

Remove it, and switch the Gloas producers of those sentinels (the preferences dispatcher and the request-auth round) to withCode so callers and tests can still identify them. The sentinel table test covers both Gloas runners. - The §6 envelope publish gets its own counter by outcome instead of being counted under the proposer's failed submissions: the block and the envelope are two publishes of one duty, and a reveal failing after the block landed is its own signal. --- protocol/v2/ssv/runner/observability.go | 21 +++++++++++++++++-- protocol/v2/ssv/runner/proposer.go | 6 +++--- .../v2/ssv/runner/proposer_preferences.go | 7 +------ .../proposer_preferences_request_auth.go | 4 ++-- .../ssv/runner/proposer_preferences_test.go | 3 ++- protocol/v2/ssv/runner/ptc_attester.go | 5 ----- .../v2/ssv/runner/runner_validations_test.go | 6 ++++++ 7 files changed, 33 insertions(+), 19 deletions(-) diff --git a/protocol/v2/ssv/runner/observability.go b/protocol/v2/ssv/runner/observability.go index c8f307cad1..ddc8e9af9e 100644 --- a/protocol/v2/ssv/runner/observability.go +++ b/protocol/v2/ssv/runner/observability.go @@ -137,6 +137,12 @@ var ( metric.WithUnit("{envelope}"), metric.WithDescription("threshold-signed Gloas execution-payload envelopes by whether this operator is the one that built them"))) + envelopePublishCounter = metrics.New( + meter.Int64Counter( + observability.InstrumentName(observabilityNamespace, "envelope.publishes"), + metric.WithUnit("{publish}"), + metric.WithDescription("Gloas execution-payload envelope publishes by the builder operator (SIP #94 §6), by outcome"))) + requestAuthReconstructionCounter = metrics.New( meter.Int64Counter( observability.InstrumentName(observabilityNamespace, "request_auth.reconstructions"), @@ -198,8 +204,8 @@ func recordProposalBuildSource(ctx context.Context, source proposalBuildSource) // holds the full payload bytes and publishes, so per operator an "other" share is expected and benign — // the signal is cluster-wide: a signed envelope no operator matched is a reveal miss (the cluster decided // a payload_root nobody can publish the payload for), which this makes countable instead of inferable only -// from the absence of a publish log.

The view is the head-event cache the beacon client already keeps: a new HeadRootAtSlot accessor returns the block root a head event named for a slot. The committee runner reads it once, when it builds the value checker at instance start, so re-proposals and the decided value are checked against the same knowledge, as the SIP requires. Without a view the check is skipped, and another block's payload status stays the leader's call. --- beacon/goclient/attest.go | 10 ++++ beacon/goclient/attest_test.go | 17 +++++++ beacon/goclient/goclient.go | 3 +- protocol/v2/blockchain/beacon/client.go | 4 ++ protocol/v2/blockchain/beacon/mock_client.go | 30 ++++++++++++ protocol/v2/ssv/runner/committee.go | 8 +++- protocol/v2/ssv/runner/committee_test.go | 46 +++++++++++++++++++ protocol/v2/ssv/spectest/value_checker.go | 1 + protocol/v2/ssv/value_check.go | 33 +++++++++---- protocol/v2/ssv/value_check_test.go | 20 +++++++- .../v2/testing/temp_testing_beacon_network.go | 7 +++ 11 files changed, 167 insertions(+), 12 deletions(-) diff --git a/beacon/goclient/attest.go b/beacon/goclient/attest.go index 804785f0bb..752d25e589 100644 --- a/beacon/goclient/attest.go +++ b/beacon/goclient/attest.go @@ -137,6 +137,16 @@ func requestGloasAttestationData(ctx context.Context, httpClient *http.Client, a return resp.Data, nil } +// HeadRootAtSlot returns the block root a head event named for slot, if one arrived within the cache's +// window — the operator's own knowledge that the block at that root has that slot (SIP #94 §2). +func (gc *GoClient) HeadRootAtSlot(slot phase0.Slot) (phase0.Root, bool) { + item := gc.headCache.Get(slot) + if item == nil { + return phase0.Root{}, false + } + return item.Value(), true +} + // verifyAndRefetchIfStale checks attestation data against cached head root. // If mismatch detected, waits briefly then re-fetches. // Returns (attestationData, stale) where stale=true means data may be outdated. diff --git a/beacon/goclient/attest_test.go b/beacon/goclient/attest_test.go index a327fc92fe..c0649bed3e 100644 --- a/beacon/goclient/attest_test.go +++ b/beacon/goclient/attest_test.go @@ -744,6 +744,23 @@ func TestVerifyAndRefetchIfStale_CacheMiss(t *testing.T) { require.True(t, stale, "unverified data should be marked stale on cache miss") } +// HeadRootAtSlot exposes the head-event cache as the operator's own view for the same-slot check: the +// root a head event named for the slot, or no view. +func TestHeadRootAtSlot(t *testing.T) { + gc := &GoClient{ + headCache: ttlcache.New[phase0.Slot, phase0.Root](), + log: zap.NewNop(), + } + gc.headCache.Set(100, phase0.Root{0x01}, ttlcache.DefaultTTL) + + root, ok := gc.HeadRootAtSlot(100) + require.True(t, ok) + require.Equal(t, phase0.Root{0x01}, root) + + _, ok = gc.HeadRootAtSlot(101) + require.False(t, ok) +} + func TestVerifyAndRefetchIfStale_CacheHit_Match(t *testing.T) { expectedRoot := phase0.Root{0x01, 0x02, 0x03} diff --git a/beacon/goclient/goclient.go b/beacon/goclient/goclient.go index 7b2f120df6..fd457d178c 100644 --- a/beacon/goclient/goclient.go +++ b/beacon/goclient/goclient.go @@ -197,7 +197,8 @@ type GoClient struct { // activatedClients tracks which clients have been activated before (for reconnection detection) activatedClients *hashmap.Map[string, struct{}] -

00:00:00 2001 From: iurii Date: Tue, 15 Sep 2026 14:00:53 +0300 Subject: [PATCH 179/228] review follow-ups: cache the envelope match, decode the decided value once, shared submit outcome - The builder match is evaluated once, when the value is decided, into a per-duty state the publish path reads instead of re-hashing the payload; a match that could not be established is warned once and is neither counted as a build match nor logged as "did not build" at publish. - A post-consensus quorum whose roots cannot be resolved keeps the reveal data while the duty is still running (the lost quorum was the block's, the envelope's may still fire) and releases it once the duty has finished (the lost quorum can only have been the envelope's). - The decided Gloas value is decoded once per quorum and handed to the block submit and the envelope publish; the expected-roots derivation is shared with the interface method. - SubmitOutcomeAttribute labels the envelope-publish and builder-preferences counters, under a namespaced key like the other attributes. - The stale-head check reuses HeadRootAtSlot; the two slot-round state tests are named for what they exercise; the p2p broadcast guard reads the interval of the slot the broadcast lands in. - The aggregate fixture generator records the commit it ran at, the all-forks generation step it needs, and its output, so the pinned constants can be checked without a pyspec install. --- beacon/goclient/attest.go | 5 +- .../validation/proposer_preferences_test.go | 6 +- message/validation/request_auth_test.go | 4 +- network/p2p/p2p_test.go | 28

The beacon client now remembers each epoch's last fetched root for the proposer lookahead, and the runner builds under it when its own fetch fails — the root the scheduler emitted for, from the same client. On the scheduler's side, a reorg recheck whose fetch failed was lost: the tick had consumed the flag, and an emitted epoch is skipped on every later tick.

A packet may carry 1 to 8 entries; entries whose root isn't frozen here are skipped without costing the ones that match, and early packets are stashed entry by entry. Message validation checks a validator-role packet's entry limit with the structural rules, so an over-long packet is rejected before a budget can ignore it, and budgets request auths by the packet's new roots. - Builder auth data defaults to the URL's hostname (builder-specs' get_default_auth_data, derived through ssv-spec); a URL with no default fails at config load, and URLs are capped at MAX_BUILDER_URL_SIZE. - The §6 reveal goes out only once this operator has submitted the block, so a bad block share next to a good envelope share can no longer publish the envelope ahead of its block. - Proposer-preferences validation state lives for the role's whole acceptance window, and validator registrations are ignored from the epoch after the Gloas fork. - A proposer value for a slot other than the running duty's is rejected by the value check, one decided anyway is not signed, and post-consensus partials are validated against the running duty's slot. - The PTC runner clears its observation only once a new duty is accepted, and a post-consensus packet that repeats an expected root is rejected. - The proposer's per-duty Gloas state is one struct, reset as a whole. --- beacon/goclient/attest.go | 16 +- beacon/goclient/attest_test.go | 86 ++++++++ config/config.example.yaml | 6 +- docs/EXTERNAL_BUILDERS.md | 9 +- go.mod | 2 +- go.sum | 4 +- message/validation/const.go | 4 + message/validation/errors.go | 1 + message/validation/partial_validation.go | 91 ++++++--- message/validation/proposer_gloas_test.go | 1 + .../validation/proposer_preferences_test.go | 84 ++++++++ message/validation/request_auth_test.go | 95 +++++++++ message/validation/validation.go | 14 +- operator/validator/controller.go | 9 +- protocol/v2/ssv/runner/proposer.go | 148 ++++++++------ .../v2/ssv/runner/proposer_preferences.go | 30 ++- .../proposer_preferences_request_auth.go | 109 +++++++---- protocol/v2/ssv/runner/proposer_test.go | 185 ++++++++++++++---- protocol/v2/ssv/runner/ptc_attester.go | 9 +- protocol/v2/ssv/runner/ptc_attester_test.go | 17 ++ protocol/v2/ssv/runner/request_auth_test.go | 131 ++++++++++++- protocol/v2/ssv/runner/runner_validations.go | 46 ++--- protocol/v2/ssv/spectest/value_checker.go | 3 + protocol/v2/ssv/testing/runner.go | 4 +- protocol/v2/ssv/value_check.go | 46 +++-- protocol/v2/ssv/value_check_test.go | 25 ++- protocol/v2/types/gloas/builder_entry.go | 38 +++- protocol/v2/types/gloas/builder_entry_test.go | 60 +++++- .../gloas/produce_builder_config_test.go | 6 +- protocol/v2/types/gloas/request_auth.go | 12 +- ssvsigner/go.mod | 2 +- ssvsigner/go.sum | 4 +- 32 files changed, 1035 insertions(+), 262 deletions(-) diff --git a/beacon/goclient/attest.go b/beacon/goclient/attest.go index b1814e2c19..0e39d70c7e 100644 --- a/beacon/goclient/attest.go +++ b/beacon/goclient/attest.go @@ -66,15 +66,25 @@ func (gc *GoClient) AttesterDuties(ctx context.Context, epoch phase0.Epoch, vali // the result is cached for a short duration and shared with later callers. // It also verifies the returned head against cached HeadEvent root and re-fetches if stale. func (gc *GoClient) GetAttestationData(ctx context.Context, slot phase0.Slot) (*phase0.AttestationData, spec.DataVersion, error) { + // A caller that is already done would only start or join a fetch nobody waits for. + if err := ctx.Err(); err != nil { + return nil, DataVersionNil, err + } + result, err, _ := gc.attestationReqInflight.Do(slot, func() (*phase0.AttestationData, error) { if cachedResult := gc.attestationDataCache.Get(slot); cachedResult != nil { return cachedResult.Value(), nil } - // Detach from the leader caller's ctx so its cancellation doesn't fail the other callers - // whose requests were collapsed into this one (mirrors domainDataReqInflight); the - // underlying multi-client fetch carries its own timeout. + // Detach from the leader's cancellation so it doesn't fail the callers joined into this request (as + // with domainDataReqInflight), but keep its deadline: it bounds the fetch, and verifyAndRefetchIfStale + // skips the stale-data refetch when too little time is left.

Comments now cite the spec that defines the behaviour (SIP-94 §5 for request auths, §7 for their validation budgets, beacon-APIs#630 for the produce body and the builder preferences) or just describe it. The builders doc still names the issue as the design record. One stale rule line is corrected on the way: preference partials are budgeted by distinct root, not capped at one. --- beacon/goclient/builder_preferences.go | 2 +- message/validation/const.go | 4 +-- message/validation/partial_validation.go | 10 +++--- message/validation/request_auth_test.go | 8 ++--- message/validation/seen_msg_types.go | 5 ++- message/validation/signer_state.go | 2 +- operator/validator/controller.go | 4 +-- protocol/v2/blockchain/beacon/client.go | 4 +-- protocol/v2/ssv/request_auth_cache.go | 8 ++--- protocol/v2/ssv/runner/observability.go | 36 +++++++++---------- protocol/v2/ssv/runner/proposer.go | 12 +++---- .../v2/ssv/runner/proposer_preferences.go | 12 +++---- .../proposer_preferences_request_auth.go | 18 +++++----- protocol/v2/ssv/runner/request_auth_test.go | 13 ++++--- protocol/v2/types/gloas/builder_entry.go | 8 ++--- .../types/gloas/builder_preferences_entry.go | 10 +++--- .../v2/types/gloas/produce_builder_config.go | 2 +- ssvsigner/ekm/remote_key_manager.go | 2 +- 18 files changed, 79 insertions(+), 81 deletions(-) diff --git a/beacon/goclient/builder_preferences.go b/beacon/goclient/builder_preferences.go index 5968f24738..fea321671e 100644 --- a/beacon/goclient/builder_preferences.go +++ b/beacon/goclient/builder_preferences.go @@ -14,7 +14,7 @@ import ( // has no call for it, so SubmitBuilderPreferences is a hand-rolled JSON POST. const builderPreferencesPath = "/eth/v1/validator/builder_preferences" -// SubmitBuilderPreferences submits the ahead-of-time per-builder preferences (issue #2962 phase 3) to +// SubmitBuilderPreferences submits the ahead-of-time per-builder preferences (beacon-APIs#630) to // every beacon client, succeeding if at least one accepts them; each beacon node forwards every entry to // its builder's submitBuilderPreferences.

The fallback then drops it and the next honest share brings the root back to quorum, but the duty had already been recorded as failed, and a duty concludes once, so the recovery that submitted the block still counted as a failure. The proposer now tags such a reconstruct failure as recoverable, as the aggregator and committee runners do, in all three of its reconstructs (RANDAO, the pre-Gloas block, the Gloas block), and records the phase durations only once the signature reconstructs. The reconstruction combines every share of the root, so a root still at quorum after the fallback dropped a bad share is never crossed again. The envelope, whose shares keep arriving while it waits for the block, could hold one bad share among more than a quorum, and its reveal would then never go out. The reconstruct is now retried on the remaining shares right away. With no bad share to drop the failure is terminal: the duty fails, or the reveal is settled as lost and its data released rather than retried on every later quorum. The Gloas quorum handler now resolves the decided value and its signing roots once per duty, and RunningDutySlot's comment no longer claims a decided instance still processes proposals: the controller skips it. --- protocol/v2/ssv/runner/proposer.go | 126 +++++++++++++-------- protocol/v2/ssv/runner/proposer_test.go | 141 ++++++++++++++++++++++++ 2 files changed, 220 insertions(+), 47 deletions(-) diff --git a/protocol/v2/ssv/runner/proposer.go b/protocol/v2/ssv/runner/proposer.go index b95d6d3bbc..089ad8c539 100644 --- a/protocol/v2/ssv/runner/proposer.go +++ b/protocol/v2/ssv/runner/proposer.go @@ -86,15 +86,19 @@ type gloasDutyState struct { producedEnvelope *gloas.ProducedEnvelope // envelopeMatch caches matchProducedEnvelope's outcome, set once the value is decided. envelopeMatch envelopeMatch - // envelopeSigningRoot is the decided value's §6 envelope signing root, zero when none is expected - // (external bid).

The next honest share brought only the bad root back to quorum, and the runner went to consensus on that one subnet, leaving out the rest. Pre-consensus now also reconstructs the roots already at quorum, and holds the decision while a root waits to come back, so consensus runs on every subnet's contribution. Post-consensus submits each root's contribution once it reconstructs: a root that fails to reconstruct or to submit no longer holds the others back, and the contributions submitted before a rejected one are counted. withCode keeps the reconstruct failure recoverable under its spec code; its type and doc now say it tags any error, as it already did beyond the sentinels. --- protocol/v2/ssv/runner/error.go | 24 ++-- protocol/v2/ssv/runner/error_test.go | 7 ++ .../ssv/runner/sync_committee_contribution.go | 115 +++++++++++------- ...tee_contribution_preconsensus_flow_test.go | 44 ++++++- .../sync_committee_contribution_test.go | 112 +++++++++++++++++ 5 files changed, 245 insertions(+), 57 deletions(-) diff --git a/protocol/v2/ssv/runner/error.go b/protocol/v2/ssv/runner/error.go index ccb8ccd92c..6504dc044d 100644 --- a/protocol/v2/ssv/runner/error.go +++ b/protocol/v2/ssv/runner/error.go @@ -59,23 +59,23 @@ func IsRetryable(err error) bool { return errors.As(err, &retryableErr) } -// codedSentinel pairs one of the sentinels above with the spec error code it reports. spectypes.WrapError -// alone cannot carry a sentinel: the spec's Error type has no Unwrap, so anything it wraps is invisible -// to errors.Is.

The node did this only for validator-set changes: after a reorg it refetched the affected epochs but kept checking against the old view until the refetch landed, so an honest one-shot partial for a proposer the reorg had moved could be dropped for good. A reorg now marks the epochs it refetches stale until their refetch lands; at an epoch's last slot the current epoch isn't refetched, so it isn't marked. The handler's comments, and the reorg tests', said the current epoch's proposers follow the current duty dependent root; under the Fulu lookahead they follow the previous one, which the current root descends from. Two leftover mentions of a §6 envelope check are gone. --- message/validation/common_checks.go | 6 +-- operator/duties/dutystore/duties.go | 19 ++++---- operator/duties/proposer.go | 22 ++++++--- operator/duties/proposer_test.go | 72 ++++++++++++++++++++++++++--- 4 files changed, 94 insertions(+), 25 deletions(-) diff --git a/message/validation/common_checks.go b/message/validation/common_checks.go index de2f0e5053..d236aee2ba 100644 --- a/message/validation/common_checks.go +++ b/message/validation/common_checks.go @@ -206,9 +206,9 @@ func (mv *messageValidator) validateBeaconDuty( // Rule: For a proposer-preferences message, require a real proposer assignment for the validator at // the slot — but only from a fetched AND fresh epoch.

When the fallback finds no bad share, as with a share set that doesn't combine to the validator's key, the root stays at quorum and more shares can't fix it: each retry failed the same way, and the duty was recorded as stuck at the slot's end rather than failed. Both now reconstruct through reconstructQuorumSig: such a failure is terminal and concludes the duty failed with the reason, after the other validators' messages are submitted as before; a root still at quorum after a drop is retried at once; one left below quorum stays recoverable.

The value check pins a Gloas block's proposer to the duty's validator (ssv-spec#647), so a leader stamping another index fails consensus instead of having the cluster sign a block the beacon node rejects. A Gloas-slot validator-registration duty is rejected before it starts, leaving no running duty behind. The spec now also publishes the §6 reveal after a failed block submit, as the node does, so the proposer's comment no longer calls that a deviation. The Gloas test block is proposed by the testing duties' validator, as in the spec. --- go.mod | 2 +- go.sum | 4 +- protocol/v2/ssv/runner/proposer.go | 4 +- .../v2/ssv/runner/validator_registration.go | 17 +++++---- .../ssv/runner/validator_registration_test.go | 20 +++++----- protocol/v2/ssv/value_check.go | 6 +++ protocol/v2/ssv/value_check_test.go | 38 +++++++++++++++---- protocol/v2/types/gloas/testing.go | 3 ++ ssvsigner/go.mod | 2 +- ssvsigner/go.sum | 4 +- 10 files changed, 65 insertions(+), 35 deletions(-) diff --git a/go.mod b/go.mod index 432c29745b..b69aa100bd 100644 --- a/go.mod +++ b/go.mod @@ -40,7 +40,7 @@ require ( github.com/sourcegraph/conc v0.3.0 github.com/spf13/cobra v1.8.1 github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131 - github.com/ssvlabs/ssv-spec v1.2.3-0.20260923084155-b6e81b2f0ea4 + github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5 github.com/ssvlabs/ssv/ssvsigner v0.0.0-20260415125841-05316f77d5e5 github.com/status-im/keycard-go v0.2.0 github.com/stretchr/testify v1.11.1 diff --git a/go.sum b/go.sum index ff22ee169c..691b672dc9 100644 --- a/go.sum +++ b/go.sum @@ -749,8 +749,8 @@ github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131 h1:qafg github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131/go.mod h1:tjzhmMzrc0Lzc/OMW1h9Mz8AhmKH7FQC/nFiMNJ0bd8= github.com/ssvlabs/go-eth2-client v0.6.31-0.20260831132123-66dd18fc8288 h1:OTiNcXOCVXpTNTR0x5IVnzYgXNUZzAQ8oC94KOMFkOg= github.com/ssvlabs/go-eth2-client v0.6.31-0.20260831132123-66dd18fc8288/go.mod h1:yhVnKAzIsFhtawbq6k/rA/Dy4vsPpu2Z2cGdQVrIjd0= -github.com/ssvlabs/ssv-spec v1.2.3-0.20260923084155-b6e81b2f0ea4 h1:FXs+WAwaBE3dj5nzChkuAgcvTGyF7x55hzScc1/6WNI= -github.com/ssvlabs/ssv-spec v1.2.3-0.20260923084155-b6e81b2f0ea4/go.mod h1:/fb7Okhw5vhldMlMhcXePMSgyBn6uCICqp5L3RtLcLw= +github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5 h1:R1bIxvr1x6iZ3jLNWuY4OLd8iKFvMjfog8kNTsJz/qw= +github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5/go.mod h1:/fb7Okhw5vhldMlMhcXePMSgyBn6uCICqp5L3RtLcLw= github.com/status-im/keycard-go v0.2.0 h1:QDLFswOQu1r5jsycloeQh3bVU8n/NatHHaZobtDnDzA= github.com/status-im/keycard-go v0.2.0/go.mod h1:wlp8ZLbsmrF6g6WjugPAx+IzoLrkdf9+mHxBEeo3Hbg= github.com/stretchr/objx v0.1.0/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= diff --git a/protocol/v2/ssv/runner/proposer.go b/protocol/v2/ssv/runner/proposer.go index 9c6a6a7644..432c5c644f 100644 --- a/protocol/v2/ssv/runner/proposer.go +++ b/protocol/v2/ssv/runner/proposer.go @@ -642,8 +642,8 @@ func (r *ProposerRunner) reconstructPostConsensusSig(root [32]byte) (phase0.BLSS // slot: the block root and, on the self-build path, the §6 blinded-envelope root, which reach quorum // independently (SIP #94 §4/§6).

Alias it to the spec's type and drop the copy, so the committee runner decides, and validates, exactly the spec's value. decidedAttestationVote now validates both vote forms: checkpoints set, index 0 or 1, source before target. The value check already validates every decided value, so this guards the post-consensus paths against that check regressing. Both value checks call Validate too, so the Gloas check now tests the index before the epochs, as the spec does. The proposer-preferences dispatcher rejects a partial of any type other than preference and request-auth with the spec's ProposerPreferencesUnexpectedPartialSigTypeErrorCode. The spec checks in the per-slot runner; the node's dispatcher stashes every partial before routing it, so the check sits ahead of the stash. --- .../v2/ssv/runner/proposer_preferences.go | 7 + .../ssv/runner/proposer_preferences_test.go | 30 +++- protocol/v2/ssv/runner/type_assertions.go | 17 ++- .../v2/ssv/runner/type_assertions_test.go | 15 +- protocol/v2/ssv/value_check.go | 14 +- protocol/v2/ssv/value_check_test.go | 10 +- protocol/v2/types/gloas/beacon_vote.go | 27 ---- protocol/v2/types/gloas/doc.go | 10 +- protocol/v2/types/gloas/generate.yaml | 2 - .../v2/types/gloas/gloasbeaconvote_ssz.go | 144 ------------------ protocol/v2/types/gloas/spec_aliases.go | 12 +- 11 files changed, 82 insertions(+), 206 deletions(-) delete mode 100644 protocol/v2/types/gloas/beacon_vote.go delete mode 100644 protocol/v2/types/gloas/gloasbeaconvote_ssz.go diff --git a/protocol/v2/ssv/runner/proposer_preferences.go b/protocol/v2/ssv/runner/proposer_preferences.go index c34aa170ce..744ec149ce 100644 --- a/protocol/v2/ssv/runner/proposer_preferences.go +++ b/protocol/v2/ssv/runner/proposer_preferences.go @@ -161,6 +161,13 @@ func (r *ProposerPreferencesRunner) StartNewDuty(ctx context.Context, logger *za } func (r *ProposerPreferencesRunner) ProcessPreConsensus(ctx context.Context, logger *zap.Logger, signedMsg *spectypes.PartialSignatureMessages) error { + // The §5 duty runs two pre-consensus rounds, preference and request-auth.

From 2ebe147aabe722c6e6e51bbcf40d9ee0154208f0 Mon Sep 17 00:00:00 2001 From: iurii Date: Thu, 24 Sep 2026 16:52:05 +0300 Subject: [PATCH 214/228] review follow-ups: conclude a duty on errors after its decision; PTC horizon, preference re-emissions, validation state An error after a runner's instance decides now concludes the duty failed, in every runner that decides: proposer, aggregator, sync-committee contribution, committee and aggregator committee. So does a decided value the runner can't take up, one that fails to decode or fails the local value check. A decided instance never decides again, so these used to surface only as "stuck" at the deadline. A doppelganger skip still leaves the duty open: the block, and on Gloas the builder operator's reveal, can still go out from the other operators' partials. The PTC outcome horizon is the duty slot's end plus the spec's MAXIMUM_GOSSIP_CLOCK_DISPARITY. Gossip ignores a payload attestation once its slot is over, and only the next slot's block can include it, so a quorum later than that no longer counts as a success. A proposer-preferences re-emission that can't rebuild its preference keeps converging on the one the slot already broadcast, instead of taking the slot over with nothing frozen and dropping the partials gathered for it. The dispatcher returns nil for a partial it stashes, so early partials no longer show up as dropped, with failed trace spans. Message validation keeps a spare slot in the preferences ring, for networks whose slots are shorter than the late and early margins together, and the checks that run before signature verification read peer state without adding it. Comments: Boole is out of the fork-lag stop comment, stateTTL says every access restarts it, and the config source says why it is read without the lock. Tests: the runners' decide helpers return a conclusion channel and the first ProcessConsensus error, so the failure tests reuse them, and a signer that fails one signing domain stands in for a failed post-consensus signature. --- beacon/goclient/goclient.go | 7 +- message/validation/consensus_state_test.go | 23 ++++ message/validation/consensus_validation.go | 20 +-- message/validation/partial_validation.go | 8 +- .../validation/proposer_preferences_test.go | 38 ++++-- message/validation/signer_state.go | 11 ++ message/validation/validation.go | 22 ++-- protocol/v2/ssv/runner/aggregator.go | 10 +- .../v2/ssv/runner/aggregator_committee.go | 10 +- .../ssv/runner/aggregator_committee_test.go | 52 +++++--- ...gator_postconsensus_classification_test.go | 40 ++++-- protocol/v2/ssv/runner/committee.go | 14 +- ...ittee_postconsensus_classification_test.go | 47 +++---- protocol/v2/ssv/runner/committee_test.go | 22 +++- protocol/v2/ssv/runner/proposer.go | 12 +- .../v2/ssv/runner/proposer_preferences.go | 49 ++++--- .../ssv/runner/proposer_preferences_test.go | 124 +++++++++++++++--- protocol/v2/ssv/runner/proposer_test.go | 83 +++++++----- protocol/v2/ssv/runner/request_auth_test.go | 9 +- protocol/v2/ssv/runner/runner.go | 74 ++++++----- .../v2/ssv/runner/runner_deadline_test.go | 40 +++--- .../v2/ssv/runner/runner_validations_test.go | 22 ++++ .../ssv/runner/sync_committee_contribution.go | 10 +- .../sync_committee_contribution_test.go | 36 +++-- 24 files changed, 554 insertions(+), 229 deletions(-) diff --git a/beacon/goclient/goclient.go b/beacon/goclient/goclient.go index 30a138a8ba..a541b8686b 100644 --- a/beacon/goclient/goclient.go +++ b/beacon/goclient/goclient.go @@ -117,7 +117,8 @@ type GoClient struct { beaconConfig *networkconfig.Beacon beaconConfigInit chan struct{} // beaconConfigSource is the address of the client beaconConfig was taken from, named when another - // client's fork schedule lags or leads it. + // client's fork schedule lags or leads it.

Its comment said that concludes no outcome, but with the deferred markDutyFailed only a cancellation is dropped: an expired duty deadline now concludes the duty failed, which is the right outcome for a duty that ran out of time. The comment says so, and the done-context test covers both cases. peekPeer returns a copy of the recorded peer state, and the limit checks bind it once, so no check allocates for an unknown peer and none looks it up twice. The note next to the §5 publish-finality caveat now records the other §5 caveat: a re-emission that can't build its preference keeps the one already broadcast, which after a dependent_root change is stale, so the duty is reported stuck at the proposal slot. --- message/validation/consensus_state_test.go | 2 +- message/validation/consensus_validation.go | 21 +++---- message/validation/partial_validation.go | 9 +-- message/validation/signer_state.go | 10 ++-- protocol/v2/ssv/runner/committee.go | 8 +-- ...ittee_postconsensus_classification_test.go | 60 ++++++++++++------- .../v2/ssv/runner/proposer_preferences.go | 4 ++ 7 files changed, 69 insertions(+), 45 deletions(-) diff --git a/message/validation/consensus_state_test.go b/message/validation/consensus_state_test.go index e942895082..00567390cb 100644 --- a/message/validation/consensus_state_test.go +++ b/message/validation/consensus_state_test.go @@ -167,6 +167,6 @@ func TestSignerStateForSlotRound_PeekPeerDoesNotAdd(t *testing.T) { s.Peer(verified).SeenMsgTypes.recordPostConsensus() require.Len(t, s.Peers, 1) -

The test now wires the checker the same way and still sees a value decided for another slot refused before anything is signed. --- go.mod | 2 +- go.sum | 4 ++-- protocol/v2/ssv/runner/proposer.go | 6 ------ protocol/v2/ssv/runner/proposer_test.go | 9 ++++++--- protocol/v2/ssv/value_check.go | 7 ++++--- ssvsigner/go.mod | 2 +- ssvsigner/go.sum | 4 ++-- 7 files changed, 16 insertions(+), 18 deletions(-) diff --git a/go.mod b/go.mod index b69aa100bd..2a3392a42a 100644 --- a/go.mod +++ b/go.mod @@ -40,7 +40,7 @@ require ( github.com/sourcegraph/conc v0.3.0 github.com/spf13/cobra v1.8.1 github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131 - github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5 + github.com/ssvlabs/ssv-spec v1.2.3-0.20260924161701-0c82ee096544 github.com/ssvlabs/ssv/ssvsigner v0.0.0-20260415125841-05316f77d5e5 github.com/status-im/keycard-go v0.2.0 github.com/stretchr/testify v1.11.1 diff --git a/go.sum b/go.sum index 691b672dc9..813854b699 100644 --- a/go.sum +++ b/go.sum @@ -749,8 +749,8 @@ github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131 h1:qafg github.com/ssvlabs/eth2-key-manager v1.5.7-0.20260901124029-39a18877e131/go.mod h1:tjzhmMzrc0Lzc/OMW1h9Mz8AhmKH7FQC/nFiMNJ0bd8= github.com/ssvlabs/go-eth2-client v0.6.31-0.20260831132123-66dd18fc8288 h1:OTiNcXOCVXpTNTR0x5IVnzYgXNUZzAQ8oC94KOMFkOg= github.com/ssvlabs/go-eth2-client v0.6.31-0.20260831132123-66dd18fc8288/go.mod h1:yhVnKAzIsFhtawbq6k/rA/Dy4vsPpu2Z2cGdQVrIjd0= -github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5 h1:R1bIxvr1x6iZ3jLNWuY4OLd8iKFvMjfog8kNTsJz/qw= -github.com/ssvlabs/ssv-spec v1.2.3-0.20260923184617-dae50b8d00b5/go.mod h1:/fb7Okhw5vhldMlMhcXePMSgyBn6uCICqp5L3RtLcLw= +github.com/ssvlabs/ssv-spec v1.2.3-0.20260924161701-0c82ee096544 h1:R3IaYBAWnuyImBScok23hqUaofQAwoTiErm0jXMH+RQ= +github.com/ssvlabs/ssv-spec v1.2.3-0.20260924161701-0c82ee096544/go.mod h1:/fb7Okhw5vhldMlMhcXePMSgyBn6uCICqp5L3RtLcLw= github.com/status-im/keycard-go v0.2.0 h1:QDLFswOQu1r5jsycloeQh3bVU8n/NatHHaZobtDnDzA= github.com/status-im/keycard-go v0.2.0/go.mod h1:wlp8ZLbsmrF6g6WjugPAx+IzoLrkdf9+mHxBEeo3Hbg= github.com/stretchr/objx v0.1.0/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= diff --git a/protocol/v2/ssv/runner/proposer.go b/protocol/v2/ssv/runner/proposer.go index 708c3643ec..8d375c48be 100644 --- a/protocol/v2/ssv/runner/proposer.go +++ b/protocol/v2/ssv/runner/proposer.go @@ -425,12 +425,6 @@ func (r *ProposerRunner) ProcessConsensus(ctx context.Context, logger *zap.Logge if err != nil { return fmt.Errorf("current validator duty: %w", err) } - // Backstop for the value check's running-slot check (SIP #94 §4): if a value for another slot is decided - // anyway (more than f Byzantine operators, or an injected decided message), don't sign a block for a duty - // this runner isn't running. - if cd.Duty.Slot != duty.Slot { - return spectypes.NewError(spectypes.ProposerDutySlotMismatchErrorCode, "decided value duty slot does not match running duty slot") - } var ( blkRootToSign spectypes.HashRoot diff --git a/protocol/v2/ssv/runner/proposer_test.go b/protocol/v2/ssv/runner/proposer_test.go index 2a5db6ef6e..2448f7cf70 100644 --- a/protocol/v2/ssv/runner/proposer_test.go +++ b/protocol/v2/ssv/runner/proposer_test.go @@ -882,15 +882,18 @@ func TestProposerRunnerPostConsensusValidatesRunningSlot(t *testing.T) { require.ErrorContains(t, err, "invalid partial sig slot: 7, expected slot: 8") } -// If a value for another slot is decided anyway, the proposer refuses to sign it: the post-decide backstop for -// the value check's running-slot check (SIP #94 §4).

A proposer QBFT instance starts ~1.1-1.5s in, so with the shared 2s QuickTimeout a round change starts round 2 after the deadline: an event that is usually recoverable today becomes usually fatal. Give the proposer its own budget of 1.5s. The timer stays anchored at instance start, and no other role changes. 1.5s is bounded by measurement rather than taste: across 30 days of mainnet the slowest round 1 that went on to decide took 1148ms, so this never fires on a round 1 that would have succeeded, while 1000ms would have fired on 5-12 real duties a month. Operators can override it with ProposerQuickTimeout / PROPOSER_QUICK_TIMEOUT, accepted between 1148ms and 2s. The bounds are hard, following ProposerDelayEPBS rather than ProposerDelay: below the floor the budget measurably times out rounds that would have decided, above it a round change cannot land at all, so neither is a risk an operator can usefully accept. Setting 2s restores prior behavior without a code change. Not fork-gated. There is no message, signature or domain change, and pre-Gloas the shorter budget is a strict improvement. A mixed cluster is never worse than today: upgraded operators round-change at 1.5s, the rest at 2s, and once f+1 have upgraded the partial-quorum rule pulls the rest along. SIP-102's other requirement, that a proposer instance stop at round 2 rather than climb to the cluster-wide cutoff, is implemented generically in #3041 and is deliberately not duplicated here. * cli/operator: keep validateProposerQuickTimeout a pure predicate validateProposerQuickTimeout both validated and logged, so it had to take a *zap.Logger. Its sibling validateProposerDelay stays a pure predicate and leaves its Warn to resolveAndValidate, next to the call site. Drop the logger parameter and move the non-default Info up into resolveAndValidate, alongside the dangerous-ProposerDelay warn, so the two paths are symmetric and the validator is side-effect-free. The tests already go through resolveAndValidate, so they cover the moved log unchanged. * qbft/roundtimer: stop implying the ProposerQuickTimeout floor has margin The MinProposerQuickTimeout comment read as though nothing gets cut off at the floor itself, when 1148ms is the slowest round 1 we observed deciding, not a value below it. Configuring exactly the floor races that duty: the expiry and the consensus message reach the same queue with no tie-break rule. Say so. The floor marks the edge of the measured band; the margin lives in the 1500ms default, which clears the observation by 352ms. No behavior change. * qbft/roundtimer: note the committee-wide constraint on WithProposerQuickTimeout The warning that ProposerQuickTimeout must match across every operator of a shared committee lived only in config.example.yaml and the env-description, so it was invisible from the code side where the option is actually applied. Mirror it onto the WithProposerQuickTimeout godoc, including the rollout window as the one sanctioned exception. Comment only. * qbft/roundtimer: raise the ProposerQuickTimeout floor to 1250ms The floor sat at 1148ms, the slowest round 1 observed to decide, so the accepted range admitted a configuration SIP-102's own design goal rules out: the goal asks the budget to stay above that observation with margin, and at exactly the observation the expiry and the consensus message reach the same queue with no tie-break. TestProposerQuickTimeoutBounds encoded the asymmetry directly, holding the default to Greater while the floor only had to be Equal. Raise the floor to 1250ms, SIP-102's own alternative to the 1500ms default. Every accepted value now clears the observation outright, so the bounds test asserts the same strict inequality for the floor as for the default, and the floor still sits 250ms under the default so downward tuning in an incident is unaffected. Drops the comment added in f15baab40 that justified the zero-margin floor instead of fixing it. 1148ms and 1249ms join the rejected boundary cases. * qbft/roundtimer: correct the claim that proposer rounds 3+ are unreachable RoundTimeout's doc said message validation's round-2 cap made QuickTimeoutThreshold and the SlowTimeout branch unreachable for the proposer. The cap only makes peers drop the messages on receipt. Locally UponRoundTimeout bumps unconditionally and IsRelevant() is Round < CutOffRound with the role-independent cutoff of 12, so a proposer instance really does climb rounds 3 through 11 and arm the two-minute SlowTimeout for 9 through 11 - the tail #3041 is about. Say that instead: those rounds are wasted work, not dead code. Same correction for the "unreachable on the wire" line in the TestRoundTimeoutOffset comment, since the messages are broadcast and only dropped on receipt. Comments only. * qbft/roundtimer: start the DefaultProposerQuickTimeout doc with its identifier The comment opened with "ProposerQuickTimeout is ...", which is the config key, not the constant it documents. Godoc convention is to lead with the identifier. * cli/operator: scope the proposerQuickTimeout log assertions to their own log Both assertions read every record the observer captured at InfoLevel, so they asserted something about all of resolveAndValidate: any Info added anywhere in it would fail these tests under a ProposerQuickTimeout name. Filter by message snippet so they only speak to this behavior. * docs: retune the ProposerDelay guidance for the 1.5s proposer budget MEV_CONSIDERATIONS derived its "~1.2s maximum reasonable ProposerDelay" from a 2s round-1 budget. SIP-102 makes that budget 1.5s for the proposer, so the same constants now give ~700ms, and the doc was recommending a value roughly 500ms too large - landing an operator who follows it in exactly the regime the SIP exists to prevent. It is the only operator-facing doc doing arithmetic on this budget and it sits outside the change that invalidated it. Correct the number, say it moved and that anyone tuned against the old guidance should retune, and point operators who raised ProposerQuickTimeout at their own configured value. Also note the budget is anchored at instance start rather than slot start, which the equation approximates away. State explicitly why maxSafeProposerDelay stays at 1s: it is a backstop against broken configurations, not the recommended ceiling, and lowering it to ~700ms would refuse startup for nodes that are merely suboptimal. * operator/validator: pin the ControllerOptions hop of the ProposerQuickTimeout chain timer_config_test.go claimed that deleting any assignment along ControllerOptions -> CommonOptions -> Validator -> roundtimer.New would be caught, but the test starts at CommonOptions. The one hop it did not cover, controller.go:217, is the only field-by-field struct copy in the chain and so the likeliest place for the value to be dropped silently. Add TestNewControllerPropagatesProposerQuickTimeout to cover it, verified by deleting the assignment and watching it fail, and correct the other test's comment to claim only what it actually pins. * message/validation: stop the round-search loop stepping by the wrong budget The loop that searches for a time-into-slot yielding a target round advanced by QuickTimeout (2s), but the estimator advances the proposer by DefaultProposerQuickTimeout (1.5s) since SIP-102. For the proposer a 2s step visits rounds 1,2,3,5,6,7,9,... - rounds 4 and 8 are unreachable. It terminates today only because the proposer target is round 3; any future maxRound change putting it at 4 or 8 would hang the suite instead of failing it. Step by a granularity smaller than any role's budget and bound the search so a miss fails with the role and round rather than spinning. * qbft/roundtimer: retire values the floor raise left stale Three leftovers from raising the floor to 1250ms and from the proposer getting its own budget: - TestWithProposerQuickTimeout and timer_config_test both armed 1200ms, now below MinProposerQuickTimeout. The option layer does not validate so nothing broke, but timer_config_test exists to show an operator's configured value reaching the timer, and 1200ms is not one an operator can configure. Both use 1400ms, already the in-range probe in config_test.go. - The proposer row in TestEstimatedRoundAt still fed QuickTimeout as its time-into-slot. It passed only by accident (2s/1.5s still lands in round 2) and no longer sat on the boundary it was written to probe. Use DefaultProposerQuickTimeout. - MaxProposerQuickTimeout restated 2s as a literal while its doc called it the pre-SIP-102 budget, a claim only true while QuickTimeout is also 2s. Derive it. * qbft/roundtimer: pass the quick budget into roundTimeoutForRound explicitly roundTimeoutForRound derived its per-round budget from defaultQuickTimeoutForRole, i.e. always the protocol default, never this timer's configured one. That is inert today only because RoundRelativeRole keeps the proposer out of the slot- synchronized branch entirely. The day ssvlabs/ssv#2429 flips that predicate, the proposer falls through to this function and an operator's configured ProposerQuickTimeout stops being honored - while validation, the startup log and the whole config chain keep reporting the value that is no longer armed. Make quick a parameter so each caller states whose budget it means: RoundTimeout passes t.quickTimeout(), the tests pass defaultQuickTimeoutForRole to keep modelling a peer. No behavior change today, since the two agree for every role that currently reaches this path. * qbft/roundtimer: stop overstating the pre-Gloas and rollout safety Two claims in the DefaultProposerQuickTimeout block did not survive scrutiny. "The pre-Gloas effect is a strict improvement" counted only where round 2 starts. A round 1 that would have decided between 1.5s and 2.0s is now cut off where it previously succeeded, so it is a trade the 1148ms measurement makes unlikely rather than impossible. Likewise "never worse than today" claims more than 30 days of data can support; scope it to that data. Also record why round 2 runs on a budget measured from round 1: a round 2 needing longer has already missed the deadline, so sizing it separately would buy nothing. Comments only. * qbft/roundtimer: the proposer stops at its cap now that #3041 landed Rebasing onto epbs-gloas picked up CutOffRoundFor, which wires CutOffRoundFor(RoleProposer) = 3 into the instance's GetCutOffRound. The RoundTimeout doc still described the world before that: local instance unstoppable, rounds 3 through 11 armed, SlowTimeout reached for 9 through 11, and #3041 named as future work. All four are false on this base - the proposer now arms rounds 1 and 2 only and never reaches QuickTimeoutThreshold. * cli/operator: make the SIP-102 proposer round timeout an on/off switch Replace the ProposerQuickTimeout duration (1250ms-2s) with a ShortProposerRoundTimeout bool, default on. On arms the SIP-102 1.5s proposer round budget; off restores the pre-SIP-102 2s budget, which is the rollback lever. The range bounds and their validation go away since operators no longer enter a value. Below cli the switch is carried inverted as LegacyProposerRoundTimeout, so the zero value of every options struct keeps the SIP-102 default and a path that forgets to wire it cannot silently fall back to 2s. * cli/operator: pin the ShortProposerRoundTimeout inversion in newNode * docs: model ProposerDelay on the two-round worst case and require a committee-wide rollback * qbft/roundtimer: correct comments the switch rework and #3041 left stale * qbft/roundtimer: store the legacy switch on RoundTimer instead of a duration * tests: dedupe the ShortProposerRoundTimeout load cases and drop duration-era names * docs: keep MEV_CONSIDERATIONS out of this PR, the rewrite moves to #3058 * cli/operator: expose the rollback as LegacyProposerRoundTimeout, default off * qbft/roundtimer: address iurii's round-4 nits * cli/operator: load LegacyProposerRoundTimeout through YAML and env in a test The env var name lived only in the struct tag, so a typo there would leave the rollback silently inert. Spell both key names out literally in a load test, and hoist the minimal-config writer it shares with Test_config_load_trueDefaultBools. * qbft/roundtimer: scope the 1148ms claim to its window and order the layers top-down * tests: fold the duplicate proposer-default and Gloas head-start tests, fix an Equal arg order TestProposerRoundTimeoutArmsProposerQuickTimeout pinned what the "no option" subtest of TestWithLegacyProposerRoundTimeout already did, and TestGloasHeadStartsTrackRetimedDeadlines re-checked round1HeadStart against its own input. Fold their assertions and doc into the surviving tests, adding the missing aggregator-committee Gloas row.

But the decided value is taken up, so the other operators' partials can still reach quorum and this operator then submits: the duty succeeded while its outcome had already been reported failed, since concludeDuty keeps the first outcome. The five deciding runners now note the error instead, and the duty watcher reports it as the failure only if nothing concludes the duty by its deadline, rather than as stuck. A decided value the runner can't take up still concludes the duty failed at once. --- protocol/v2/ssv/runner/aggregator.go | 7 ++-- .../v2/ssv/runner/aggregator_committee.go | 7 ++-- .../ssv/runner/aggregator_committee_test.go | 8 ++-- ...gator_postconsensus_classification_test.go | 8 ++-- protocol/v2/ssv/runner/committee.go | 11 ++--- ...ittee_postconsensus_classification_test.go | 38 +++++++++++------- protocol/v2/ssv/runner/proposer.go | 7 ++-- protocol/v2/ssv/runner/runner.go | 40 ++++++++++++++++--- .../v2/ssv/runner/runner_deadline_test.go | 39 ++++++++++++++++++ .../v2/ssv/runner/runner_validations_test.go | 19 ++++++++- .../ssv/runner/sync_committee_contribution.go | 7 ++-- .../sync_committee_contribution_test.go | 8 ++-- 12 files changed, 149 insertions(+), 50 deletions(-) diff --git a/protocol/v2/ssv/runner/aggregator.go b/protocol/v2/ssv/runner/aggregator.go index e2e773884e..47d67eea55 100644 --- a/protocol/v2/ssv/runner/aggregator.go +++ b/protocol/v2/ssv/runner/aggregator.go @@ -205,11 +205,12 @@ func (r *AggregatorRunner) ProcessConsensus(ctx context.Context, logger *zap.Log return nil } - // A decided instance never decides again, so an error from here on is final: conclude the duty failed - // rather than leave the watcher to report it stuck. + // An error from here on doesn't end the duty: the other operators' partials can still reach quorum on the + // decided value, and this operator then completes the duty anyway.
