Summary

Hermes Shields recovery could finish root-controller activation before the Hermes parent process confirmed that it consumed the release. A later Shields transaction could then replace the active transaction while the earlier startup gate resumed.

This change adds a two-stage, parent-bound release acknowledgement. The startup gate prepares an acknowledgement for the exact release digest, transaction, nonce, and parent process identity. The Hermes parent commits it after it receives the nonce. The root controller removes recovery authority only after it accepts that acknowledgement.

The activation helper uses a 485-second deadline. The response reader has a separate 30-second allowance. Missing, pending, malformed, or mismatched acknowledgements fail closed and retain recovery authority.

A later exact run exposed a back-to-back transition race during timed auto-restore lock confirmation. Timed auto-restore now performs one Hermes runtime provider state mutation, waits, then verifies the settled locked posture read-only. Detected drift still retries the full mutation and remains fail-closed.

The final repair retains durable lifecycle authority until the Docker root broker session is confirmed absent. It cleans finalized sessions left by the published parent before recovery or another acquisition, and treats inspection ambiguity as incomplete cleanup.

The residual fix installs a fixed root-owned transport broker in the managed image instead of sending caller-generated Python through Docker stdin. The controller accepts only that broker under the installed isolated Python interpreter and verifies the interpreter device and inode through /proc before trusting its parent process.

Original failure evidence: run 32841422570, attempt 2, Hermes Shields job 97810111319.

Final-candidate image evidence: managed-image run 33284249489 passed on exact head 8f10786334a98e4e6f2307d90149682299739770. It includes direct Hermes startup, all-agent managed runtime activation, and exact OpenClaw managed-image MCP discovery pass 1 and pass 2. This proves the candidate-owned image cohort is coherent; it does not substitute for issue #9485 exact Hermes acceptance.

The first paired issue attempt, run 33282533296, dispatched mcp-bridge,hermes-shields-config together for candidate a2a59e2d7bf5de277231232f41518d0ad076626a. The trusted PR workflow selected published main managed-image cohort 1806106f9126636b3e4a6d3cef620aaf07e199f0, which predates the installed broker, so Hermes MCP and Hermes Shields both reported root helper transport did not become available. The original root helper acquire did not complete successfully signature was absent. Shields cleanup passed; MCP endpoint and sandbox cleanup passed, while pre-destroy MCP removal failed against the retained fence. This mixed CLI/image deployment is not counted as candidate acceptance. After merge and coherent main image publication, the exact pair must pass together twice on one exact main SHA.

Changes

  • Bind activation release to the exact release digest, transaction, nonce, and parent process identity.
  • Let the Hermes parent commit the pending acknowledgement after it receives the exact nonce.
  • Retain recovery authority when acknowledgement evidence is missing, pending, malformed, or mismatched.
  • Bound the activation helper at 485 seconds and give the response reader a separate 30-second allowance.
  • Keep replayed checkpoint and health work inside the activation deadline.
  • Retry a timed-out Docker response copy only inside the response allowance.
  • Return the fixed release-ack-write-failed result without exposing operating-system error text.
  • Test the release handoff, fail-closed states, transport bounds, and redacted write failure.
  • Retry PID-reuse races only within the existing process-state deadline.
  • Re-confirm timed auto-restore with a read-only settled-posture observation instead of starting a redundant second Hermes runtime provider state mutation.
  • Retain the durable lifecycle receipt until the exact Docker root broker session is confirmed absent.
  • Clean finalized sessions left by the published parent before surface recovery or another acquisition.
  • Treat session inspection errors as incomplete cleanup, then retain the receipt for retry.
  • Consolidate the Hermes privileged gate wrapper and replace source-derived test fixtures with behavior coverage.
  • Install a fixed root-owned transport broker in every managed and portable Hermes image context.
  • Bind accepted broker ancestry to the installed isolated Python interpreter filesystem identity.

Commit 05aed98d91cb2f01d31a24c4bcdd89387eece28b replaces a redundant second provider mutation with read-only settled-posture verification; drift still triggers bounded full retry. Commit 15141cdaf7a0d77092ce4cd03e269716292b5042 applies the same read-only confirmation to timed auto-restore. Neither widens authority or changes credential, network, filesystem, or recovery policy. Commit 6e66abad83600ee17114ca2b45d29ce8824f0c0f passed an independent nine-category security review. It retains lifecycle authority until exact Docker session absence, fails closed on inspection ambiguity, preserves non-Docker behavior, and closes the published-parent finalized-session recovery state.

📝 Walkthrough

Walkthrough

The release flow now uses an authenticated, atomically staged acknowledgement. Hermes promotes the acknowledgement before startup completes. Docker activation now uses bounded, phase-specific deadlines and shared retry timeouts.

Changes

Runtime state mutation release flow

Layer / File(s) Summary
Release acknowledgement contract and gate
scripts/runtime-state-mutation-startup-gate.py, scripts/runtime-state-mutation-control.py, test/state/runtime-state-mutation-startup-gate.test.ts
The startup gate defines the acknowledgement schema and acknowledge action. It validates release state, process identity, and existing acknowledgements before atomically writing pending state.
Release acknowledgement orchestration
agents/hermes/start.sh, scripts/runtime-state-mutation-control.py, test/state/runtime-state-mutation-release-ack.test.ts, test/state/runtime-state-mutation-hermes-publisher.test.ts, test/state/runtime-state-mutation-control.test.ts
Hermes validates and promotes pending acknowledgements with the configured mv binary. The controller binds acknowledgements to the release payload, waits for a matching receipt, validates it, and cleans up safely.

Docker activation timing

Layer / File(s) Summary
Bounded Docker activation timing
src/lib/onboard/runtime-provider/docker-state-mutation.ts, src/lib/onboard/runtime-provider/docker-state-mutation.test.ts, test/helpers/docker-state-mutation-harness.ts
Activation uses separate retry, checkpoint, health, replay, and completion allowances. Signal retries share one deadline. Transport copies and response reads use remaining-time limits, with explicit timeout failures.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 60c25

This change tightens Hermes release handoff and transport timeout behavior. It is mergeable with explicit owner awareness: the test harness still models signal-replay timing differently from production, and shell acknowledgement behavior is not fully validated through execution, leaving bounded regression-detection risk.

Reviewed commit 577bd049b4edf63e7e826fb95d1e4052b9757688 and the complete runtime/helper/test diff.

The trusted Manual PR Run is immutably bound to this commit, base fa34f2aca47a690a465d1a9dbd268e57b515c738, and workflow 4f82ea594a94456274e91fc44f85a954e0415310: https://github.com/NVIDIA/NemoClaw/actions/runs/32869482070 (correlation fab24236-3b7f-48b4-86ae-b5d3eeeb6249). The dispatch receipt, candidate evidence manifest, and risk signal match that binding.

The exact owned target still fails with the original signature:

  • fixture preparation, non-root Hermes onboarding, and fresh runtime-state verification passed;
  • first-cycle shields down passed in 4.894s;
  • the immediate shields status then blocked for 549.141s and exited 2 with Runtime provider state mutation failed: root helper transport response did not arrive; retained-fence recovery reported the same failure;
  • the first Shields cycle failed after 556.548s, so the remaining posture/restart/preservation phases were skipped;
  • cleanup passed for the sandbox, gateway, and fake inference endpoint.

The 480-second activation-helper timeout and 495-second transport-read budget therefore do not preserve a response in the live boundary this PR owns. The deterministic tests prove only that 480 is greater than three nominal 150-second controller windows and that a signal replay shares one deadline. They do not prove that the broker publishes a terminal response and the client reads it inside the outer deadline under the retained activation path. The live result also shows that the 15-second transport margin is not a sufficient end-to-end bound.

Please derive and instrument the actual retained-activation phases, keep the broker action and response-reader deadlines ordered with explicit publication/copy/scheduling allowance, and add a deterministic transport-level regression that proves a response is returned at the deadline boundary. Do not replace this with another unexplained timeout increase. Then rerun hermes-shields-config. The PR description must also be updated: it still says the runtime correction will follow and that the new regression is deliberately red, although this commit contains an implementation and green unit tests.

Security review: Secrets/Credentials PASS; Input Validation/Data Sanitization PASS; Authentication/Authorization PASS; Dependencies PASS; Error Handling/Logging WARNING because the terminal diagnostic cannot distinguish helper timeout from response-publication/read failure; Cryptography/Data Protection PASS; Configuration/Security Headers PASS; Security Testing FAIL because the mocked deadline tests miss the live broker/transport contract; System Security WARNING for the 549-second synchronous availability stall, although the privileged helper remains bounded and no authority is widened. I found no committed secret, caller-authored command, path injection, or weakened root-helper identity/fence validation.

The ordinary changes and growth-guardrail failures are GitHub installation API-rate-limit failures, and the dependency advisor failed during inference configuration. Those are infrastructure failures, but the exact candidate-owned Shields failure independently blocks approval.

The Hermes Shields run for commit 577bd04 still fails at the boundary this PR changes. Activation uses a 480-second helper deadline. The response reader allows 495 seconds and reserves no explicit time for broker publication, scheduling, and a final Docker copy. The run waited 549.141 seconds and then reported that no root-helper response arrived. The new tests check timeout arithmetic and replay sharing, but they do not prove response publication and retrieval at the deadline boundary. Please instrument the retained-activation phases, order the helper and reader deadlines with explicit transport allowance, add a deterministic transport-level regression, and rerun hermes-shields-config.

Use the remaining deadline for the replayed helper call.

Line 363 starts the replay with the full helperTimeout. The production broker gives the replay only the remaining action deadline. If a test capture consumes part of the first attempt before returning a signal status, this harness permits a full second window and can accept behavior that production times out.

These assertions only find strings in the scripts. They do not prove that Hermes promotes the pending acknowledgement or holds startup when promotion fails. Execute the startup path with mocked gate and mv commands, then assert the observable file state and exit behavior.

As per path instructions, tests must prefer observable outcomes through the public boundary over source-text assertions.

Current head efc5b2afd6d3f5ad11fb7f70fadc0d237e6b9be9: I reviewed Advisor PRA-1 and am not treating it as a blocker.

The pending and final acknowledgement files represent two distinct execution boundaries. The sandbox-identity startup gate validates the exact release binding and prepares the nonce-bound payload. The resumed parent shell publishes the final file only after the gate child returns. That final promotion proves the shell itself regained execution across the release handoff. Publishing the final acknowledgement inside the child gate, as suggested, would let the controller observe completion before the parent shell crosses that scheduling boundary and would weaken the race proof this change adds.

The shell step remains fail-closed: /usr/bin/mv is fixed and availability-checked, the nonce has a strict 64-character lowercase-hex grammar, paths remain under the fixed handoff root, and the controller opens the final file with O_NOFOLLOW and validates its owner, mode, link count, stable identity, exact release digest, transaction, nonce, and start-process binding. A path swap can only make validation fail; it cannot make an invalid acknowledgement pass.

The exact documentation review receipt is current. The remaining approval gate is a passing exact-head hermes-shields-config run and independent review after that evidence is available.

[P3] State that over-range values are clamped

The implementation clamps every positive integer above 10000 to 10000, while this table only calls 10000 the maximum and separately lists inputs that fall back to the default. Add a short sentence saying values above 10000 are clamped so operators can predict the effective wait. This is documentation-only and does not block the current security fix.

[P1] Keep the stale-base replay fixture complete

Adding the broker to this unconditional ownership and mode replay breaks the extracted Dockerfile fixture in test/runtime/sandbox/sandbox-rlimit-hooks.test.ts because that fixture never stages the new path. Required CLI shard 2 is red, and the focused local test reproduces the same missing-file failure at line 770. Stage the broker in that fixture and assert its root-only mode so the stale-base replay remains executable and the required suite returns green.

[P1] Bind the fixed broker executable, not only its argv

This accepts any root process whose command-line tail names the broker path and a transaction, but it never checks command[0] or compares the captured executable device/inode with the installed Hermes Python. I reproduced this head accepting a ProcessIdentity with argv0 /tmp/forged-python and an arbitrary executable inode. That defeats the point of replacing dynamic source with an image-owned broker if a different process can be recorded as the trusted parent. Bind /proc//exe to the fixed interpreter (following the reviewed installed path), require the exact argv0, and add a regression where the broker tail matches but executable identity differs and must fail closed.

Fixed in 4bfd3f6621843b8a2db201f565674c14109c15e9. _transport_broker_reference() now requires the exact Hermes Python argv0, checks a stable root-owned/non-writable stat of that installed interpreter across parent capture, and requires the captured /proc/<pid>/exe device/inode to match it. The controller harness now rejects both the matching-tail/different-executable case and a matching-executable/spoofed-argv0 case. Exact-head focused evidence: controller 15/15, Docker transport 40/40, repository checks, CLI typecheck, changed-test selection, pre-commit, and pre-push passed; fresh CI and Review Advisor are running.

Reviewed exact head 7649bfb.

The three prior blockers are resolved: executable identity is carried in process references, fractional settle values use the default, and the replay regression exercises the full broker. This head also installs the broker as a root-owned image helper and documents over-range clamping.

Two new blockers remain:

  1. The controller authenticates the fixed broker from root UID and argv tail only. It does not require the fixed interpreter argv0 or bind the captured executable device/inode to the installed Hermes Python. I reproduced a forged executable with the expected broker tail being accepted. The exact-line P1 has the required binding and regression.

  2. The Dockerfile replay now references the broker, but test/runtime/sandbox/sandbox-rlimit-hooks.test.ts does not stage it. Exact required CLI shard 2 fails with the missing broker path, and the focused local test reproduces 1 failure out of 9. The exact-line P1 identifies the fixture contract.

Exact-head local evidence: 58 of 58 focused CLI tests passed, 23 of 23 runtime-state integration tests passed, CLI type-check and diff hygiene passed, and the installed broker parses. The stale-base replay test fails as described. Commit verification and product scope under #10155 are valid; required CI is red and current-head automated review is not yet settled.

Nine-category security verdict: PASS secrets, input validation, dependencies, error handling, and cryptography; WARNING configuration; FAIL authentication and least privilege, security testing, and holistic posture until the broker executable identity and red required test are fixed.

Final-head Review Advisor disposition for a2a59e2d7bf5de277231232f41518d0ad076626a

Advisor run: https://github.com/NVIDIA/NemoClaw/actions/runs/33282242710

Eight specialists reported no finding. The architecture report claimed Podman starts the new transport broker but skips its Docker-only cleanup. That finding is a surrounding-guard misread and requires no code change:

  • ensureHelperTransportAuthorized(...) at docker-state-mutation.ts:1955 is inside if (options.providerId === DOCKER_PROVIDER_ID) (:1954-1956).
  • invokeHelperAuthorized(...) uses the broker only inside its Docker branch (:1537-1540); Podman takes the direct fixed-helper branch (:1542-1551).
  • Therefore the Docker-only terminal broker cleanup at :1269 / :2596 matches the only provider that creates a broker session.

Focused verification on this exact head: npx vitest run --project cli src/lib/onboard/runtime-provider/podman-state-mutation.test.ts --fileParallelism=false — 1 file, 4 tests passed.

Re-reviewed exact head a2a59e2d7bf5de277231232f41518d0ad076626a. The stale-base fixture blocker is fixed: the broker is staged and its root-only mode asserted, and exact-head required CI is fully green (63 success, 7 skipped). All six commits since my reviewed head are GitHub Verified. Exact-head provider tests pass 40/40, CLI typecheck and Python syntax checks pass, and diff hygiene is clean. The local stale-base suite reaches the new broker fixture; its remaining 1/9 failure is only this host missing PyYAML, while the required CI lane passes. The exact-head Advisor settled; its Podman cleanup report is a surrounding-guard false positive as the author explained.

One P1 security blocker remains unchanged: _transport_broker_reference() still authenticates the parent from root UID plus the argv tail only. It never requires the fixed interpreter argv0 or binds the captured executable device/inode to the installed Hermes Python. I reproduced this exact head accepting a ProcessIdentity with argv0 /tmp/forged-python and arbitrary executable inode 99999. The original exact-line thread remains applicable: #10272 (comment).

Security verdict: PASS secrets, input validation, dependencies, error handling, and cryptography; WARNING configuration; FAIL authentication and least privilege, security testing, and holistic posture until the fixed broker parent is executable-bound with a negative regression. Please fix that final blocker; I will rereview the next exact head.

Final-head Review Advisor disposition for 8f10786334a98e4e6f2307d90149682299739770

Advisor run: https://github.com/NVIDIA/NemoClaw/actions/runs/33284248748

  • The documentation finding on the prior head was valid and is fixed in 8f1078633: the settle-window reference now states that chattr +i provides the durable lock only when the best-effort operation succeeds, and that no durable lock is available when it is unavailable or fails. npm run docs passed.
  • Eight final-head specialists report no issue. The architecture report proposes moving the provider-neutral implementation out of docker-state-mutation.ts; that ownership is pre-existing current-main design from feat: add Podman qualification and state mutation #9187, not introduced by this PR. Current main already contains container-state-mutation.ts with the explicit compatibility decision to retain the established Docker implementation while candidate providers consume only the facade, and this PR changes neither that facade nor podman-state-mutation.ts. The final-head Podman surface test passes 4/4, including its direct-helper path. No architecture refactor is required for this residual Docker transport fix.

The final Advisor trust specialist reports no security defect and specifically confirms the broker parent is bound to the exact interpreter argv and executable identity.

Final-head re-review evidence:

  • All 63 final-head checks passed; no failed or pending checks.
  • Managed-image run 33284249489 passed direct Hermes startup, all-agent managed runtime activation, and exact OpenClaw managed-image MCP discovery twice: https://github.com/NVIDIA/NemoClaw/actions/runs/33284249489
  • Review Advisor run 33284248748 passed all specialist jobs. The architecture note is about the pre-existing provider facade placement; the residual fix leaves that facade and the Podman consumer unchanged. The documentation fallback finding was fixed in 8f10786.
  • The latest P1 is fixed by binding the broker parent to the installed isolated Python interpreter device/inode, with regression coverage for spoofed argv0 and a different executable identity. Thread: fix(runtime): preserve Hermes activation transport response #10272 (comment)
  • The first paired issue run 33282533296 is documented in the PR body as a mixed candidate-CLI / pre-broker-main-image cohort and is not counted as acceptance. After merge and coherent main-image publication, I will run mcp-bridge and hermes-shields-config together twice on one exact main SHA.

@cjagwani, please re-review the final head. No merge is requested from automation; maintainer approval and merge remain separate.

Approved exact head 8f10786334a98e4e6f2307d90149682299739770.

The requested broker-identity fix is complete: the controller now requires the fixed Hermes interpreter argv, verifies the interpreter is a root-owned non-writable regular file, proves its filesystem object is stable across capture, and binds the live parent executable to the same device/inode. The new harness rejects both a forged interpreter path and a forged executable identity.

All four commits since my prior review are GitHub Verified. All current required CI is green. CodeRabbit's only thread is resolved, and all nine exact-head PR Review Advisor specialists were inspected; the architecture note points to the provider facade already present on current main and is not introduced by this PR.

Isolated exact-head verification passed: runtime mutation controller tests 15/15, Windows MXC composition tests 2/2 after generating required build artifacts, policy-boundary build, and diff check. The nine-category security pass found no remaining issue in secrets, input validation, authorization/least privilege, dependencies, cryptography, error handling, configuration, security testing, or holistic lifecycle behavior.

…eview candidates (#10898)

**Summary:** Treat each pushed commit as a stable review candidate,
batch automated feedback before
repairs, and merge `main` only when the candidate actually requires it.

## Outcome

PR follow-up now treats each pushed commit as one candidate. Contributor
and maintainer agents wait
for required CI and scheduled automated reviews, batch valid repairs,
constrain base integrations,
and reject feedback-driven scope expansion before publishing another
revision.

## Reason

### Main refreshes

This is a cross-team throughput problem, not an individual contributor
habit. In the latest 150 PRs
merged by the core team from August 27 at 05:43 UTC through September 2
at 19:15 UTC, 2026:

- 89 PRs, or 59%, contained at least one explicit merge from `main`.
- Those PRs contained 514 explicit `main` refreshes.
- The average was 3.4 refreshes per PR and the median was 1.

| PR author | PRs | PRs refreshed | `main` refreshes | Average per PR |
Median per PR |
|---|---:|---:|---:|---:|---:|
| `rsliter` | 22 | 19 | 144 | 6.5 | 4 |
| `ericksoa` | 9 | 5 | 82 | 9.1 | 1 |
| `cjagwani` | 3 | 3 | 7 | 2.3 | 1 |
| `cv` | 46 | 14 | 45 | 1.0 | 0 |
| `prekshivyas` | 30 | 26 | 118 | 3.9 | 3 |
| `jyaunches` | 6 | 3 | 3 | 0.5 | 0.5 |
| `senthilr-nv` | 26 | 13 | 32 | 1.2 | 0.5 |
| `apurvvkumaria` | 8 | 6 | 83 | 10.4 | 9.5 |

The largest examples were #9923 with 57 refreshes, #10150 with 26,
#10396 with 22, #10692 with
20, and #10515, #10272, #10275, and #10436 with 19 each.

The average understates how bursty these refreshes are. Forty-six PRs
had at least one run of
consecutive `main` refresh commits. Across the sample, 85 such runs
contained 223 refresh commits.
Eleven PRs had 16 adjacent refresh pairs no more than five minutes
apart. Eighteen had 35 pairs no
more than ten minutes apart.

Examples show both the repeated integrations and the review work they
can invalidate:

- While this PR was being prepared, its skills-only candidate hit
base-owned `fast-uri` advisories
in both sandbox-image builds. Prekshi refreshed it at 20:51 UTC,
creating a 2,154-line merge
commit and restarting Advisor, CI, CodeQL, CodeRabbit, and E2E on a new
head.
- On Apurv's #10436, two consecutive refresh commits landed 10 seconds
apart. Each mapped to a
separate PR Advisor run, and the first run was cancelled when the second
head arrived.
- On #10618, four refresh commits appeared consecutively. The final two
were 2 minutes 20 seconds
apart and produced separate Advisor runs; the earlier run was cancelled
when the later one began.
- On Prekshi's #10692, two consecutive refresh commits were 3 minutes 8
seconds apart, and each
  produced a separate Advisor run.
- On Rebecca's #10150, four refresh commits appeared within 13 minutes
15 seconds. Prekshi authored
three and the automation bot authored one, showing that churn on an
author's PR is not necessarily
  initiated by that author.
- #10308 contained nine consecutive refresh commits. They were spread
across several days, but each
  still replaced the commit under review.

The analysis used complete paginated GitHub GraphQL commit histories. A
`main` refresh is a commit
with multiple parents whose headline names `main`, `origin/main`, or
`upstream/main`. This excludes
same-branch merges. It also excludes rebase-based base updates, so it
measures explicit main merges
rather than every possible base update. Commit timestamps identify
integrations, not push times. The
examples that claim a review restart were separately matched by refresh
SHA to PR Advisor workflow
runs.

### Batching feedback

The current Advisor expands each `synchronize` event into nine
independent specialists and publishes
their separate reviews. CodeRabbit reviews the incremental commit range.
Acting on the first finding
can therefore create another commit while the remaining specialists and
checks are still in flight,
producing overlapping or genuinely new feedback. Complete collection
makes it possible to deduplicate
findings, group them by root cause, and make one repair instead of
serial repair loops.

### Stable review candidates

Each pushed refresh replaces the commit under review and can retrigger
CI, CodeRabbit, and the PR
Advisor. Human review and approval evidence can become stale before that
fanout settles. A base
integration can also import new contracts, fixtures, and generated
identities into the candidate,
which gives incremental reviewers genuinely new material. Treating one
unchanged commit as the
candidate keeps every check and finding attached to the same code until
the complete evaluation is
ready for one repair decision.

## Changes

- Define a stable-candidate protocol in the shared PR follow-up
contract. It waits for each scheduled
Advisor specialist, CodeRabbit, and required CI on one unchanged latest
PR commit, then collects
  each specialist review from its job summary or artifact.
- Deduplicate findings and classify each as candidate-owned or
inherited, in-scope or new scope, and
  blocking or advisory before repairs begin.
- Permit candidate integration with the base only for a conflict, a
required merged dependency, or
  the final merge gate after other findings settle.
- Keep code-changing PRs draft until automated evaluation settles. Reuse
`headRefOid` and non-force
pushes as an optimistic publication guard instead of adding new shared
state.
- Stop implementation repairs that add runtime, lifecycle, security,
deployment, or
  supported-interface scope without a new decision.
- Carry the original objective, accepted scope, deferred scope, and
complete root-cause group into
  every routed repair.
- Fail closed on a failed Advisor specialist or missing artifact until a
NemoClaw maintainer chooses
  a full-workflow rerun or deferral.
- Preserve settled remote review evidence while inspecting local repair
and validator-created diffs,
  with `headRefOid` guarding against competing updates.
- Apply the same sequencing rules to maintainer approval and salvage
workflows.
- Add skill eval cases for refreshes during review, incomplete or failed
Advisor evidence, repair
scope, local publication guards, and premature ready-for-review
requests.

## Verification

- `bash
test/e2e/e2e-cloud-experimental/features/skill/lib/validate_repo_skills.sh`:
passed for all
  29 repository skills.
- Eval JSON parse for all three changed eval files: passed.
- Changed-file prek checks: passed Markdown, JSON, secret scanning, and
growth guardrails.
- Commit hooks: passed pre-commit and commitlint.
- `npm run validate:pr`: passed pre-commit, commitlint, and applicable
pre-push checks against
  canonical `main` at `f427b07d0e01b309983239dd97c989234b18c3c1`.
- `node --experimental-strip-types
tools/pr-review-advisor/render-specialist-matrix.mts`: confirmed
  nine current Advisor specialists.
- Complete Advisor reports were read for every repair candidate from
`4b67754e8` through
`ca2f47c5e`; valid findings were batched by root cause before each
repair.
- The final `ca2f47c5e` set had no valid finding. Eight specialists
reported none; the code-reduction
suggestion was rejected because `TEST-GAPS.md` can change a PR without
entering the merge or
  salvage procedures that retain the proposed prerequisite.
- Diff inspection: no secrets, API keys, or credentials.

## Review notes

- `npm run review:local` did not reach the diff. The local Advisor
sandbox gateway refused its
configuration connection, then cleanup reported `EACCES` on its
temporary context. This is
  environmental unavailable evidence, not a review finding.
- The generic `skill-creator` quick validator could not start because
the host Python environment
lacks PyYAML. The repository's dependency-free validator passed all
skills.
- On `e18ab4253`, both sandbox-image builds failed on advisories against
the base-owned
`fast-uri@3.1.5` lock. The refresh to `main` brought the existing
`3.1.6` remediation; no candidate
  source change was required.
- On `ca2f47c5e`, `test-e2e-sandbox` failed while planning the
base-owned `nim-service.local`
endpoint because it is private or reserved. The blueprint, rejection
code, and E2E script are
  unchanged from the PR base, so no candidate repair or rerun applies.

## Summary by CodeRabbit

- **Documentation**
- Updated pull request workflows to require complete, settled specialist
review evidence before review, repair, approval, integration, or
publication.
- Clarified collection of individual review results and artifacts,
including failed or missing evidence as blocking conditions.
- Required preservation of the original objective, accepted and deferred
scope, dispositions, and root-cause context throughout repairs.
- Added safeguards against scope-expanding repairs across runtime,
lifecycle, security, deployment, and supported-interface boundaries.
- Strengthened commit verification, single-commit publication,
base-branch failure handling, and fresh validation after integration.
