Resolves F-378.

teardownGasLimits is a reservation carved out of gasLimits, not an addition on top: the total a tx may consume is gasLimits, the fee limit is gasLimits × maxFeesPerGas, and a tx with a teardown call is billed the full teardownGasLimits regardless of actual teardown consumption (see gas_meter.nr and the tail output validators). Three places documented the opposite model or stayed silent:

  • how_to_pay_fees.md described gasLimits as "main execution phase" only.
  • The Gas_Settings_Components snippet (rendered on the fees page) never said teardown is inside the total.
  • getGasLimits JSDoc said the returned gasLimits excludes teardown gas, while the value is computed from totalGas which includes it.

This fixes all three, adds per-field docs to the GasSettings constructor (rendered on the fees page via the gas_settings_vars snippet), and documents the full-reservation billing behavior. Docs only, no behavior change. The unrelated hunks in general_snippets.js are prettier reformatting.

docs-developers/docs/aztec-js/aztec_js_reference.md:1909 still has the old "excluding teardown gas" sentence, so the generated reference now contradicts this comment on next. It's auto-generated, so it'd need a run of docs/scripts/aztecjs_reference_generation/update_docs.sh rather than a hand edit. Worth regenerating here? That block also still documents the old two-arg getGasLimits(simulationResult, pad), so it looks stale beyond just this line.

The committed `aztec_js_reference.md` was last generated on 2025-12-10.
Against today's aztec.js source it documents 125 symbols where the
package exports 188: 19 documented symbols no longer exist
(`AccountInterface`, `AccountWithSecretKey`, `DeploySentTx`,
`broadcastPrivateFunction`, `getGasLimits`, ...) and 82 current exports
are missing.

The v5.1.0 snapshot that production serves carries the same December
content, so this is what the live API reference shows today. The release
refreshed the CLI references, the aztec-nr API and the TypeDoc
TypeScript API in the same commit, but
`aztecjs_reference_generation/update_docs.sh` is not part of the release
checklist.

This also resolves the contradiction @nchamo spotted in #25220, where
the stale block still described the old two-argument form and said gas
limits exclude teardown gas.

### Why the generator changed too

A straight regeneration does not build, so two generator bugs are fixed
first:

- Multi-line types were emitted inside inline code spans. A type body
containing a blank line closes the span early, and its braces and angle
brackets then reach the MDX parser, failing the build with `Unexpected
end of file in expression`. Multi-line types now use a fenced code
block, matching what `format_return_type` already did. Verified this
reproduces on `merge-train/fairies` itself with none of these commits
applied.
- The table of contents built anchors with its own slug logic that
stripped underscores Docusaurus keeps, leaving `CAPABILITY_VERSION` and
the `Contract / Protocol_Contracts` section unreachable and pointing
`NO_WAIT`/`NO_FROM` at the `NoWait`/`NoFrom` headings. Anchors now
derive from the rendered heading text the way github-slugger does.

The aztec.js JSDoc edits are comment-only, and are needed because the
regenerated page otherwise fails `yarn spellcheck` on a `metadata` typo
and on `on-chain`, which is a `flagWords` entry in the root
`cspell.json`.

## Summary

Publishes `v5.2.0` as the shared release for both **Alpha (Mainnet)** and **Testnet** across developer and network/operator documentation, and removes the deprecated `v5.1.0` snapshots.

- both `mainnet` and `testnet` selectors resolve to the same `v5.2.0` snapshot
- developer and network/operator snapshots cut from the `v5.2.0` tag (`49a592109ec`), so `#include_code` snippets and version macros freeze against what shipped
- Aztec.nr, TypeScript, Aztec.js, `aztec` / `aztec-wallet` / `aztec-up` CLI, operator `aztec start` CLI and Node JSON-RPC references all regenerated at the tag
- identical generated API artifacts under the stable `mainnet` and `testnet` paths
- `networks.md` re-derived from the node RPCs and on-chain reads

A backport of this release into `v5-next` is [#25265](#25265).

## Merged `next` (2026-08-19)

`next` moved 64 commits while this was open. Merged and resolved; `yarn build` re-run green on the merged tree. Two conflicts, both around the Aztec.js reference:

- `docs/scripts/aztecjs_reference_generation/transform_to_markdown.py` — **took `next`'s version wholesale.** [#25248](#25248) landed a proper `HeadingSlugger` (github-slugger semantics including the `-1`/`-2` uniqueness suffixes) and code-block handling for multi-line types, which supersedes the two narrower fixes this PR originally carried.
- `docs/docs-developers/docs/aztec-js/aztec_js_reference.md` — **took `next`'s version.** [#25249](#25249) added `update_docs.sh --check` to `docs/bootstrap.sh`, so the committed source page must match what the generator produces from the working tree. Regenerating on the merged tree reproduces `next`'s page byte-for-byte (modulo the self-stamped timestamp) and `--check` passes.

The **v5.2.0 snapshot's** copy of that page was regenerated with `next`'s generator against the `v5.2.0` tag's `aztec.js` source, so the released snapshot gets the improved anchors and code-block formatting while still documenting v5.2.0's API.

Also reconciled from `next` into the snapshot: [#25220](#25220 clarification that `teardownGasLimits` is carved out of `gasLimits` rather than added to it. Verified true at the tag (`yarn-project/stdlib/src/gas/gas_settings.ts`: "teardown gas is reserved from gasLimits during private execution ... the effective gas available for app logic is `gasLimits - teardownGasLimits - privateOverhead`"). The other post-tag doc changes on `next` are fast-inbox / AZIP-22 work (`inbox.md`, the `MessageSent` signature and message-availability wording in `token_bridge.md` and `uniswap_swap.md`, and dropping `AZTEC_INBOX_LAG`), which is not in v5.2.0 — deliberately **not** backported, so the snapshot keeps the wording that is correct for the release.

## Release details

Verified from the node RPCs at cut time:

| | Alpha (Mainnet) | Testnet |
| --- | --- | --- |
| `nodeVersion` from RPC | `5.1.0` | `5.2.0-nightly.20260815` |
| `rollupVersion` | `4248422647` | `1821665230` |
| L1 chain id | `1` | `11155111` |

Per the instruction that the network versions are unchanged, the **Version** row in `networks.md` stays `5.1.0` for both columns; only the documentation version advances to `v5.2.0`.

Every figure in `networks.md` was re-derived rather than carried forward:

- all L1 addresses in both columns match `aztec_getNodeInfo`
- Slasher, Honk verifier, Reward Booster, Tally Slashing Proposer and Slash Payload Cloneable re-read on chain from the Rollup / Slasher / Proposer for both networks, all unchanged
- rollup version read from `getVersion()` on both rollups; chain ids from `cast chain-id`
- governance parameters re-read on chain for **both** columns: proposer quorum 600/1000 and 60/100; voting delay, duration and execution delay decoded from `getConfiguration()` (mainnet 3 d / 7 d / 2 d, testnet 12 h / 24 h / 12 h); slashing quorum 65/128 over 4 epochs (128 slots)

### The canonical SponsoredFPC address changes under v5.2.0 tooling, and the new one is not deployed

`aztec get-canonical-sponsored-fpc-address` built from the `v5.2.0` tag returns:

```
0x2ece607a8dba690c9aa4ee1d53a55286fa815543a27f9364bbaf65eb68e7315b   (class id 0x1cf37d561fb76ae2b95d3c395c3204c1dab4a6309b045a3fc17a58483c5ad2e9)
```

Testnet has nothing at that address (`aztec_getContract` returns `null`). What is deployed and funded is the v5.1.0-built FPC, `0x130925fb...923296` (class id `0x184e81e5...8673a5`), which is what this PR keeps.

The SponsoredFPC Noir source is byte-identical between `v5.1.0` and `v5.2.0` — the address moved purely because the Noir compiler went `beta.22` to `beta.25`, which changes the compiled bytecode, the contract class id, and therefore the derived address. The same thing happened at the v5.1.0 cut, where a new FPC was deployed and funded.

The consequence is worth stating plainly: `wallet.registerContract` does not validate that the supplied artifact matches the instance's class (explicit comment in `yarn-project/wallet-sdk/src/base-wallet/base_wallet.ts`), so `aztec-wallet register-contract ... SponsoredFPC` appears to succeed on v5.2.0 tooling and then fails at simulation, because the PXE only holds the `0x1cf37d...` artifact. **Either a v5.2.0-built SponsoredFPC is deployed and funded on testnet at `0x2ece...` and this PR is repointed at it, or sponsored fees on testnet stay pinned to v5.1.0 tooling.**

## Documentation content changes

### Aztec.nr: the v5.2.0 breaking change was live in three doc snippets

Note structs declared inside a `contract` block must now be `pub` (Noir `beta.25`, [#24907](#24907)). `state_variables.md` (`AddressNote`, `UintNote`), `functions/attributes.md` (`CustomNote`) and the `#[custom_note]` example in the `notes.nr` doc comment (published through `nargo doc`) all showed non-`pub` declarations that do not compile on v5.2.0. Every `.nr` **source** file the docs pull in via `#include_code` was already `pub`, so the defect was confined to prose snippets.

### Migration notes

- The `pub` note-visibility entry was filed under `## 5.1.0`, but the Noir `beta.25` bump that causes it is not in the `v5.1.0` tag. Moved to a new `## 5.2.0` section.
- Four v5.2.0 behaviour changes had no migration note at all, each verified against `v5.1.0..v5.2.0`: the zero-peer proposing gate (`SEQ_MIN_PEERS_TO_PROPOSE`), JSON-RPC internal errors moving from `-32600` to `-32603`, `GET /status` gaining a per-component JSON body (and the widened `StatusCheckFn`), and the removal of `deserializeArrayFromVector` from `@aztec/foundation/serialize`.
- The `## TBD` entries on this branch are left untouched: they describe changes on this line that have not shipped in a release yet.

### Operator / node docs

All eight new v5.2.0 env vars were missing from the CLI reference; regenerating it at the tag picks them up, along with `--proverNode.proofSubmissionTargetAddress`, which existed in v5.1.0 code but was never documented. Hand edits on top:

| File | Change |
| --- | --- |
| `reference/changelog/v5.2.md` | new page; the operator changelog stopped at v4.3.x. Plus index and sidebar entries |
| `concepts/monitoring.md` | claimed the node emits no "about to be slashed" metric; it now does, so that section carries the real logs and metrics |
| `monitoring/metrics-reference.md` | new own-validator slashing metrics section (with alert rule) and JSON-RPC server metrics section |
| `concepts/sequencer-troubleshooting.md` | the four peerless-node gates, plus the `/status` health check and `P2P_HEALTH_MIN_PEERS` |
| `reference/reading-logs.md` | five new entries: fatal p2p start failure, zero-peer warning, skipped proposal, mempool drop reasons, slash-target warning |
| `sequencer-management/governance-participation.md` | the node now stops signalling an executed payload; `GOVERNANCE_PROPOSER_FORCE_PAYLOAD_VOTE` escape hatch |
| `concepts/l1-rpc.md` | server-side filter methods are no longer required; watchers poll bounded `eth_getLogs` |
| `provider/start-node.mdx`, `solo-sequencer/start-node.mdx` | sample `nodeVersion` `5.0.0` to `5.2.0` |

Reviewed on the deploy preview by @yev.

### Developer docs

- `tutorials/js_tutorials/aave_bridge.md` pinned `@aztec/l1-artifacts` to a literal version; it now uses the version macro like every other pin on that page, so it stops going stale each release.
- `aztec-js/how_to_send_transaction.md` documents the new first-receipt-poll delay and `initialDelay` ([#25089](#25089)).
- `@aztec/viem@2.38.2` is deliberately left alone in the three tutorials that pin it: it tracks upstream `viem`, not the release line.

**Known gap, not fixed here:** the declarative deployment framework at `@aztec/aztec/deploy` ([#24685](#24685)), headlined as "New in this release", has **zero** documentation. It wants a new `aztec-js` page; that was scoped but not written, rather than shipping a half-verified page for a new API.

## Non-docs changes

Three one-line source edits, all comment-only, no behaviour change:

- `archiver/src/config.ts` and `stdlib/src/interfaces/archiver.ts` — `on-chain` to `onchain`, so the regenerated operator CLI reference passes the repo's own spellcheck (`on-chain` is a repo-wide `flagWord`)
- `noir-projects/labs/aztec-nr/aztec/src/macros/notes.nr` — the `pub` fix in the `#[custom_note]` doc comment

The equivalent `aztec.js` JSDoc fixes this PR originally carried are gone: `next` made the same corrections upstream, so the merge left nothing to change.

## Validation

`MAINNET_TAG=5.2.0 TESTNET_TAG=5.2.0 RELEASE_TYPE=mainnet COMMIT_TAG=v5.2.0 yarn build`, re-run on the merged tree:

- CSpell: 682 files, **0 issues**
- Redirect targets: 185 checked, all valid
- API reference links: 112 checked, **0 broken, 0 version mismatches**
- Docusaurus production build: **successful**
- `./scripts/aztecjs_reference_generation/update_docs.sh --check`: **✓ Reference matches aztec.js**
- no unresolved `#release_version` / `#release_network` / `#include_code` macros in either snapshot
- version configs and version lists carry one shared `v5.2.0` snapshot for both Alpha and Testnet
- generated `mainnet` and `testnet` Aztec.nr and TypeScript API directories are byte-identical
- empty `## TBD` heading stripped from the cut snapshot's migration notes

Remaining broken-anchor warnings are the pre-existing ones only (the `validator-keys|valkeys` CLI alias and the operator compose-page anchors); `onBrokenAnchors` is `warn`, so the build passes.

**Not run:** the functional validation pass (walking the guides and tutorials against a live local network). This container has no Docker daemon, so the dockerized `aztec` CLI could not be installed; everything above was produced from a source build of the tag with shims for `aztec` / `aztec-wallet` / `aztec-up`. The guides and tutorials in this snapshot are link- and spell-validated but not executed.
