Verify Task

Closes the loop between a work item's claimed acceptance and what's actually proven. Reads the V-* rows cited in the issue's ## Validation section (per the work-item template), looks each up in VALIDATION.md, runs the proof, reports green/red.

When to use

• A PR is about to claim Closes #N and you want to confirm the cited validation rows are actually green.
• A user asks "is this issue really finished?"

When NOT to use

• For an issue that cites no V-* rows (pure-doc work). There's nothing to run.
• As a substitute for code review.

Procedure

1. Resolve the work item. An issue number → gh issue view <n> and pull the V-* IDs from its ## Validation section — falling back to scanning acceptance bullets for older issues that predate the template (also check any archived tasks/done/T-*.md file the issue names as its full spec). T-0037 → read tasks/T-0037-npm-prerelease-dist-tag-channel.md frontmatter directly (the one still-in-flight file-based task).
2. Look up each V-* in VALIDATION.md. Pull the Proven by, Status, and Tracked by columns. This tells you whether the invariant is already enforced, non-blocking, CI-only, or still a declared gap.

3. Run the proof.

   Run make verify — it covers V-typecheck, V-lint, V-unit, V-tool-registry, and V-retrieval-floor in one command (requires a populated DB). It runs bun test src/mcp-contract.test.ts without ROSETTA_REAL_DB_TESTS=1, so the real-DB blocks behind V-tool-shapes and V-tool-budget are skipped — run those separately with ROSETTA_REAL_DB_TESTS=1 bun test src/mcp-contract.test.ts against a populated DB. For CI-only invariants (V-db-min-content, V-bunx-*) there is no local equivalent; those are only proven by a release run.

   For more targeted checks, map common V-* IDs to commands:

   V-* ID	Command
   V-typecheck	bun run typecheck
   V-lint	bun run lint
   V-unit	bun test
   V-tool-registry	bun test src/mcp-contract.test.ts (Block A, always runs)
   V-tool-shapes	ROSETTA_REAL_DB_TESTS=1 bun test src/mcp-contract.test.ts (Block C, needs populated DB)
   V-tool-budget	ROSETTA_REAL_DB_TESTS=1 bun test src/mcp-contract.test.ts (Block B, needs populated DB)
   V-retrieval-floor	bun run src/eval/retrieval.ts
   V-retrieval-self	bun run src/eval/self-supervised.ts
   V-canonicalize	bun test src/canonicalize.test.ts src/canonicalize.fuzz.test.ts
   V-classifier	bun test src/classify.test.ts
   V-schema-roundtrip	bun test src/schema-roundtrip.test.ts
   V-extract-videos	bun test src/extract-videos.test.ts
   V-http-handshake	bun test src/mcp-http.test.ts
   V-stdio-handshake	bun test src/mcp-stdio-client.test.ts
   V-tui-mcp-parity	bun test src/browse-parity.test.ts
   V-cli-flag-uniformity	bun test src/cli-help.test.ts
   V-db-wipe-guard	bun test src/query.test.ts
   V-release-structure	bun test src/release.test.ts

   For V-bunx-* and V-db-min-content rows, the proof lives in release.yml — these can't be cleanly run locally. Note that explicitly: "this V-* is verified by CI on the next release run."

   If a row is currently GAP in VALIDATION.md:

   • If the work item under review is the one named in Tracked by, verify that the PR adds the missing proof and updates the row away from GAP.
   • Otherwise report the row as an unresolved gap and do not recommend closing the issue.
4. Report. For each V-*:
   • ✓ pass — quote the relevant Proven by description so the user knows what just ran.
   • ✗ fail — surface the test output's failure summary.
   • ⊘ CI-only — explain that this row is verified on workflow_dispatch of release.yml; can't be checked locally.
   • ⚠ GAP — explain that the invariant is not yet proven, quote Tracked by, and only consider it satisfied if the current work item is the one closing that gap.
5. Conclusion. Recommend merging (and letting Closes #N fire) only if every row is green or legitimately CI-only. If any row is failing or still GAP, don't recommend it — point at the missing proof or failing acceptance criterion. If acceptance is only partially met, remind that follow-up issues must be opened before merge (issue-pr-linking.instructions.md).

Output format

Issue: #19 — extractor safe import pattern
Validation rows: V-db-wipe-guard

V-db-wipe-guard: ✓ pass
  Proven by: bun test src/query.test.ts (wipe-guard block)

Conclusion: rows green. PR may claim Closes #19 once acceptance bullets are all delivered.

What this skill does NOT do

• Close issues or open/merge PRs.
• Run release.yml — the user has to dispatch that themselves.
