Outcome

Local hooks select affected repository checks and reuse successful compiler validation when its inputs still match. Publication validation checks formatting without changing the committed candidate.

Reason

A source edit previously started all 19 repository checks. Explicit publication validation repeated compiler work in the subsequent push hook. Shared-boundary builds and the always-run growth gate also repeated work.

Changes

  • Add input selectors and per-check timing to the existing repository runner. Include deleted and renamed paths, and invalidate every selector when checker code or shared configuration changes. checks-runner.test.ts and validation-reuse.test.ts cover selection and failure propagation.
  • Share compiler results between validate:pr and installed push hooks. Reuse requires a clean tree and matching source, commits, dependencies, executables, environment, and required outputs. Missing or stale evidence runs the compiler. Git/npm invocation metadata is normalized before execution and hashing. validation-reuse.test.ts covers reuse, invalidation, failed checks, external loaders, ignored source, and build artifacts. File reads verify one open descriptor and reject concurrent changes. The hook entry point accepts only the three compiler checks. Each source is hashed once per fingerprint. Repository checks and Windows npm/npx commands run through Node with literal arguments; command-resolution failures return a failed check.
  • Derive read-only publication commands from the existing hook configuration. Existing whitespace fixers run on disposable copies; formatters and generators use check mode. This preserves one hook configuration. Unknown or renamed hooks must have their read-only behavior classified before execution. publication-validation.test.ts covers all nine fixer conversions, the actual repository configuration handoff, rejected formatting, dirty trees, command failures, and cleanup.
  • Use TypeScript build mode for the shared policy boundary and separate incremental caches for plugin production/tests. policy-boundary-build.test.ts verifies deleted-output recovery and rejection of new type errors.
  • Keep seven current-diff growth assertions in the always-run gate. Move the 38 parser/diagnostic tests to a separate file in the same integration project. Update contributor and agent guidance in this PR.

Verification

Latest GitHub evaluation for 66c84488d487c3193e59c72ec9bc89384974eec3 is failing, with jobs still pending. PR CI tested merge ff13d6b7305b5d584c6f0d1ba0db25e2cee162b3 with newer main f6dd9aebc535858cc94d1c72c5df1167b44cb86e. Static checks, type-checking, and shard 12 fail on missing imports in src/lib/adapters/config/live-export-source.test.ts; that file is identical to main, whose own type-check job reproduces the same four errors. Shard 3 also timed out in unchanged onboarding coverage; its four focused tests pass on both the candidate and original implementation base, so that timeout remains unclassified. No CI waiver or manual rerun is claimed. CodeRabbit completed the latest review without actionable code findings. Advisor requires green CI and has not reviewed this repair; CodeQL and remaining checks are still pending.

  • Focused implementation suite: 130 tests passed across the repository runner, cache, publication validator, policy build, and both growth-guardrail files.
  • npm run validate:pr: passed on the recorded signed candidate with a clean tree before and after validation.
  • Merged main at dab48f58c094d78c017458f4d72d6f5ca217578c, including formatting fix chore(onboard): apply pinned Oxfmt formatting #11492. Pinned Oxfmt checks now pass on both Docker bootstrap files that failed the previous CI run.
  • Installed Git pre-push hook against a disposable local bare repository: passed; all three compiler receipts retained their input/output hashes and modification times, proving that the installed hook reused them.
  • npm run check: repository-wide pre-commit and plugin coverage passed; the CLI/integration run had 35,354 passing tests and 259 failures in 31 existing files. Replaying those 31 files on unchanged implementation base aeab35b84c75c968b0b9b4e03f63ed2e6591ae00 reproduced the same 259 failures, with identical failure headers. These are inherited failures in this isolated environment, including unavailable Docker access and checkout-authority constraints. No candidate-only failure was found in that comparison. The broad run preceded the final cache refinements; all focused tests and the publication gate were rerun afterward.
  • Canonical-base repository runner: all 19 checks passed. Canonical-base compiler commands (npm run typecheck:cli, npm --prefix nemoclaw run typecheck, and npx tsc -p jsconfig.json) passed against the candidate sources.
  • Local selection sample: all 19 repository checks took 24.2 s; the nine selected for src/commands/sandbox/status.ts took 17.0 s. The initial compiler-hook run took about 23 s. The final installed-hook replay reused all three results and took 8.4 s, including Git transfer. These are local observations, not CI timing guarantees.
  • The reviewed diff contains no secrets, API keys, or credentials; the hook secret scan passed.

Review notes

Repository: NVIDIA/NemoClaw. Candidate: 66c84488d487c3193e59c72ec9bc89384974eec3. Canonical comparison: 05796cf4e47b717aa80b2d9c603946e0ec5aad0b.

The sensitive paths are AGENTS.md, .pre-commit-config.yaml, the contributor PR skill, and the six changed files under scripts/checks/. Self-review covered the complete diff, input selection, cache invalidation, mutation/failure paths, and the installed-hook boundary. On reviewed head 0f162bc5fc2a26c03ce972579f3a2ce8e7d630c1, required CI and CodeQL passed. CodeRabbit completed review 5173586863, and all nine Advisor specialist reviews were read. This repair addresses duplicate source hashing, missing conversion coverage, unclassified hooks, Windows command launching, and shared Vitest configuration selection. The new repair and sensitive paths await their next independent review. Maintainer cv marked the PR ready on September 10; this update preserves that state.

The reviewed head also had two optional managed-image runtime failures: MCP discovery pass 2 rejected stored-credential reuse (pass 1 succeeded), and Hermes activation entered sandbox Error before Ready. Runtime and workflow sources are unchanged from the integrated main. Their root causes remain unclassified; there is no demonstrated cause in these validation changes. No manual rerun, runtime repair, CI waiver, or merge approval is claimed. Advisor's command-deadline and broader candidate-execution trust proposals concern inherited behavior; this PR preserves the external trusted-validation gate. Its separate unknown-hook read-only gap is fixed.

Local hook-equivalent checks ran in isolation; signing and upload use Git objects on the contributor host. The user requested publication and explicitly selected all five improvements. Because the candidate changes validation code, candidate commands ran in an isolated Linux ARM64 Docker checkout with networking disabled, read-only installed dependencies, and no contributor-host credentials. The canonical runner was mounted separately for its check; canonical manifests supplied the original compiler commands while TypeScript checked candidate source. The canonical validator files are unchanged between the recorded base and the previously inspected fd98dc2aeb3a37579efbf005a0e2195f7bf20a03.

Validator identity: Node 25.9.0 (SHA-256 6ddc7eec8c425db60c217241e2c9207eb299a17c227b9494655b18bb5da5a2e1), installed TypeScript compiler (1c59e77a54b186ec43fa7f3e0d3c4bb15ca5eb5ba43e96b1d3a267139eddd3e3), and tsx entry point (8729ecfb90d9d568939e4190e6f1d3317c946583b7d37a776e0c23a21c021cf8). Root and plugin lockfiles are unchanged. Local result reuse does not replace the trusted-validation gate, independent review, CI, or publication authorization.

📝 Walkthrough

Walkthrough

The change adds read-only pull-request validation, changed-file repository checks, cached compiler validation, incremental policy-boundary builds, and expanded growth-guardrail parser tests.

Changes

Validation tooling

Layer / File(s) Summary
Read-only publication validation
.agents/skills/..., scripts/checks/..., package.json, AGENTS.md, CONTRIBUTING.md, .pre-commit-config.yaml, test/repository/publication-validation.test.ts, test/helpers/vitest-watch-triggers.ts
Validation now requires a clean worktree, uses read-only hook checks, runs validation stages, rejects repository changes, and removes temporary configuration.
Changed-file repository checks
scripts/checks/run.mts, scripts/checks/validation-command.mts, test/repository/checks-runner.test.ts
Repository checks select affected checks, account for shared inputs, report durations, and execute commands without shell dispatch.
Cached compiler validation
scripts/checks/cached-command.mts, .pre-commit-config.yaml, nemoclaw/package.json, test/repository/validation-fixture.ts, test/repository/validation-reuse.test.ts
Compiler checks fingerprint inputs, environments, dependencies, executables, and outputs before reusing successful results.
Incremental policy-boundary build
package.json, test/repository/policy-boundary-build.test.ts
The policy-boundary build uses TypeScript project references. Tests cover output restoration and type-error failure.

Growth guardrail coverage

Layer / File(s) Summary
Guardrail parser and diff coverage
test/automation/pull-requests/growth-guardrail-parsers.test.ts, test/automation/pull-requests/growth-guardrails.test.ts
Tests cover parser diagnostics, budgets, control flow, renames, deletions, Git diffs, merge bases, and ancestry probes. Obsolete synthetic support was removed.
