fix(skills): preserve authorized PR follow-up

[rsliter]

Outcome

Authorized pull request workflows now continue through routine workflow and E2E changes without asking for duplicate approval. Local validator trust remains protected, with guarded hook-free draft publication and base-controlled PR validation as the fallback when candidate validation machinery changed.

Reason

The shared guidance conflated content under review with validator code executed on the contributor host. It also used broad terms such as risky and public writes that could turn workflow or E2E file changes into approval pauses even when the original task already authorized the PR lifecycle.

Changes

• Define concrete user-decision boundaries for PR follow-up and keep pending checks in the authorized heartbeat.
• Clarify that the sensitive-workflow state matrix analyzes changed runtime behavior and does not create approval requirements for branch or PR writes.
• Make the live E2E validation note require a selected manual target only when the accepted task needs that evidence.
• Separate candidate inputs from local validator machinery, add exact-state guarded hook-free publication, and require base-controlled PR validation for the draft fallback.
• Bind the hook-free fallback to a structured candidate and canonical-base receipt, a checked-in trusted-job allowlist, a draft PR, and an atomic exact-ref lease.
• Independently require a changed local validation surface before accepting hook-free publication, and render the typed fallback receipt, differing paths, and canonical base into the PR evidence.
• Bind repository-local fallback action implementations to the receipt's exact trusted workflow revision and reject non-ancestor remote commits before publication.
• Reconcile completed initial publication only from a draft PR whose complete prepared metadata matches, reject caller-writable local receipts, and permit one unchanged PR-creation retry only after fresh exact state reads.
• Add deterministic race, trusted-job, recovery, initial-publication, workflow-change, live-E2E-change, and changed-lockfile regression coverage.
• Record that authorized branch synchronization and mechanical conflict resolution do not require separate approval.

Verification

• Repository skill and configuration validation: passed; the standalone skill validator remains unavailable locally because PyYAML is not installed.
• Skill eval JSON: parsed successfully with 60 unique eval IDs.
• Focused GitHub-tool, PR-body fallback, and growth-guardrail tests: 59 passed.
• Oxfmt and Oxlint: passed for the changed TypeScript and test files.
• npm run checks:repository: passed all 18 selected repository checks.
• Pre-commit and commit-msg hooks: passed, including repository checks, growth guardrails, Markdown lint, and secret scanning.
• npm run validate:pr and pre-push publication validation passed at exact commit 8ddf5aa973b236f1e76f0f8c9678a679e8806e3a; TypeScript CLI checks passed on the latest code-changing commit.
• Initial CI failures were classified before synchronization: the assertion-budget failures came from main advancing to test(e2e): mock Brave validation and update fast-uri #12398, and one CLI shard hit a transient /proc process-exit race outside this diff.
• The first exact-head Advisor findings grouped into three root causes: hook-bypass authorization ownership, an atomic remote-ref race, and one stale skill eval.
• The next exact-head Advisor findings grouped into two root causes: caller-asserted workflow security and unrecoverable delayed commit verification. Both are repaired in the latest commit.
• The third exact-head Advisor findings grouped into five root causes: unproven branch-only recovery, completed-draft reconciliation, creation-error identity checks, receipt-bound commit enumeration, and caller handoff coverage. All are repaired in the latest commit.
• The fourth exact-head Advisor findings grouped into four root causes: base-branch identity, durable branch-only recovery, successful-create reconciliation, and missing trust-boundary rejection tests. All are repaired in the latest commit.
• The fifth exact-head Advisor findings grouped into four root causes: caller-writable local-receipt trust, incomplete recovered-PR metadata comparison, duplicate creation during completed-draft recovery, and the missing single guarded retry after inconclusive creation. All are repaired in the latest commit.
• The sixth exact-head Advisor findings grouped into two root causes: caller-supplied fallback receipts could bypass an unchanged trusted hook, and the typed PR-body gate could not represent guarded fallback evidence. Both are repaired in the latest commit.
• The seventh exact-head Advisor findings grouped into two root causes: repository-local fallback actions were not bound to the receipt's workflow revision, and the non-ancestor publication guard lacked regression coverage. Both are repaired in the latest commit.
• The eighth exact-head Advisor finding showed that the PR-body renderer still accepted caller-assembled fallback evidence. The publisher now returns the canonical validated evidence object, the renderer requires that publication result, and a forged standalone receipt is rejected.
• The ninth exact-head Advisor findings grouped into three root causes: the renderer still duplicated publisher trust, guarded branch publication and draft creation were split across calls, and inconclusive initial verification had no safe recovery disposition. The renderer no longer accepts fallback evidence; the guarded create operation now owns publication, publisher-authored disclosure, body finalization, and draft creation; inconclusive post-write verification returns an explicit branch-specific maintainer recovery procedure without retrying the absent-ref write.
• The tenth exact-head Advisor findings grouped into two root causes: guarded draft updates did not refresh commit-bound fallback evidence, and contributor guidance could still direct candidate-controlled validation. Guarded updates now require and carry publisher-authored exact-commit evidence into the PR body, and contributor guidance routes changed validation surfaces through the guarded draft workflow.
• The eleventh exact-head Advisor findings grouped into two root causes: Fern-specific guidance still named candidate-controlled validation as an unconditional fallback, and guarded initial publication dropped its branch-specific recovery blocker. Fern guidance now follows the same canonical-base trust check, and the create operation preserves the publisher's exact recovery procedure.
• The twelfth exact-head Advisor finding identified that unavailable hooks alone do not qualify for guarded draft publication when the validation surface is unchanged. Contributor and Fern guidance now require repairing the trusted hook path and reserve the guarded fallback for an actually changed validation surface that makes local validation untrusted.
• The thirteenth exact-head Advisor findings grouped into three root causes: the generic PR-body refresher retained caller-controlled fallback authority, contributor guidance still allowed rebasing, and the fallback receipt duplicated its canonical revision. Guarded publication now owns exact-commit disclosure, contributor guidance permits only merge or Update branch synchronization, and the receipt has one canonical base identity.
• A cross-task regression showed that accidental out-of-scope candidate work could still be presented as a scope choice. Shared follow-up and implementation guidance now require removing that work, applying the single mechanically supported in-scope repair, and continuing monitoring without approval.
• GitHub reports the latest published commit as Verified.
• The diff contains no secrets, API keys, or credentials.

Review notes

This PR changes sensitive repository workflow paths: AGENTS.md, .agents/**, .dsh/**, fern/AGENTS.md, and their durable regression tests. The latest commit 8ddf5aa973b236f1e76f0f8c9678a679e8806e3a addresses the complete exact-head Advisor collection and the observed cross-task approval regression. The PR remains draft while automated evaluation runs on this repair.

📝 Walkthrough

Walkthrough

This PR updates contributor guidance for PR follow-up, validation, and publication. It clarifies branch synchronization and escalation boundaries, defines guarded draft publication when local validation machinery differs from the canonical base, and distinguishes live E2E dispatch authority from workflow or E2E file changes.

Changes

Layer / File(s)	Summary
Follow-up and decision boundaries .agents/skills/_shared/pr-follow-up.md, .agents/skills/_shared/root-cause-and-state-checks.md, AGENTS.md	Updates bounded-wait handling, repair and escalation criteria, sensitive-workflow state-matrix guidance, and branch synchronization instructions.
Trusted validation and draft fallback .agents/skills/nemoclaw-contributor-create-pr/references/validation.md, .agents/skills/nemoclaw-contributor-create-pr/evals/evals.json	Defines which local validation machinery must match the canonical base and when guarded draft publication or isolated trusted-base validation is allowed. Updates evaluation expectations for these publication paths.
Workflow and live E2E publication rules .agents/skills/nemoclaw-contributor-create-pr/SKILL.md, .dsh/tools/infer_validation_for_changed_files/index.ts	Clarifies that workflow or live E2E file changes alone do not grant live-run authority or require another approval. Specifies local deterministic E2E-support validation and when missing live-run authority does not block draft publication.

Limit the approval requirement to unauthorized destructive cleanup.

The decision table requires new approval for any “destructive cleanup.” The sensitive-workflow rule states that the task or lifecycle can already authorize this behavior. Therefore, in-scope destructive cleanup is incorrectly blocked by this row.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exempt the guarded draft fallback from the local publication-validation prohibition.

The fallback requires publication without invoking changed local hooks. The repository’s publication-validation hook invokes scripts/checks/validate-pr.mts, which runs candidate hook checks and build commands. Skipping unavailable local machinery therefore leaves the local result inconclusive. The later unconditional prohibition blocks the fallback, even though static-checks provides a reachable canonical-base gate with read-only permissions and no credential passed to candidate commands.

Suggested fix

-Do not push when publication validation fails or is inconclusive.
+For a normal push, do not push when publication validation fails or is inconclusive. The guarded draft-publication fallback above is exempt from this local-result requirement when a qualifying canonical-base job and all other publication gates pass.
