docs: refresh Builder upstream status - #16
Conversation
📝 WalkthroughWalkthroughThe documentation records the 24 August 2026 project state. It updates Lodestar and Beacon API evidence, Builder implementation status, metrics and environment completion, remaining review work, upstream inputs, and Week 11 validation results. ChangesImplementation evidence reconciliation
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The PR refreshes project documentation but currently leaves an inconsistent consensus-specification baseline and stale Builder status entries, which could mislead contributors about implementation and review status. These bounded issues should be corrected before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 206: Update the Lodestar producer PoC row in the status table to identify
nflaig/builder as an unpublished, unreviewed PoC, while retaining that upstream
review is pending.
In `@docs/living-technical-note.md`:
- Line 250: Update the Builder API status table rows for builder-specs `#165` and
beacon-APIs `#630` from Open to Merged, leaving the surrounding tracker entries
unchanged.
- Line 7: Update the consensus-specs version references in the living technical
note, including the Spec target entry and the references at the indicated audit
sections, so every baseline consistently uses v1.7.0-alpha.14 matching the
pinned Lodestar unstable version.

Synchronize the Lodestar PoC status table.
The cross-client row still lists PoC pending. Identify nflaig/builder as an unpublished, unreviewed PoC, and keep upstream review pending.

Synchronize the consensus-specs baseline.
Set the references at Lines 68, 204, and 1008 to v1.7.0-alpha.14, which the pinned Lodestar commit uses. The note must use one consensus-specs audit baseline.

ethereum builder-specs pull request 165 beacon-APIs pull request 630 merged August 24
💡 Result:
As of August 24, 2026, the Ethereum Pull Requests beacon-APIs #630 and builder-specs #165 are active components of ongoing efforts to update the Ethereum proposer flow, particularly regarding ePBS (enshrined Proposer-Builder Separation) [1]. Beacon-APIs Pull Request #630, titled "Update Beacon API for parity with Builder API and KeyManager API," was created to align Beacon API naming and conventions with related changes in the KeyManager and Builder APIs [1]. It introduces updates such as the produceBlockV4 endpoint, which includes support for BuilderEntry arrays to manage proposer preferences across external builders [1]. This work specifically incorporates feedback and changes from builder-specs #165 and other related development efforts to ensure the three API specifications function as a cohesive flow [1]. While these pull requests are part of the active development process—and were specifically noted in All Core Devs (Consensus) #183 on July 23, 2026, as requiring feedback from staking pools, builders, and DVT providers—they remain in the development and review cycle rather than having been officially merged on August 24, 2026 [1][2]. The work continues to address technical requirements like payload withholding, authentication, and integration with consensus layer clients [1][2].
