+
+  The final task packet implementing the code-quality-gates spec
+  ([`docs/specifications/taskplane/code-quality-gates.md`](docs/specifications/taskplane/code-quality-gates.md),
+  section 6.4). Flips three static-analysis checks from advisory to
+  required CI gates: `Typecheck` (new — `tsc --noEmit` against
+  `extensions/tsconfig.ci.json`), `Lint (Biome)` (was already wired
+  but ran with `continue-on-error: true` until now), and
+  `Format check (Biome)` (new — `biome format --no-errors-on-unmatched .`).
+  `.github/workflows/ci.yml` runs the three steps in order before the
+  existing `Run tests` step inside the single `ci` job, so any failure
+  short-circuits the rest of the pipeline. The existing required `ci`
+  branch-protection context already covers the new gates because a
+  step failure fails the whole job.
+
+  Reviewer-agent activation: the TP-188 quality-check verification
+  section in `templates/agents/task-reviewer.md` is now fully active.
+  The temporary activation note added in TP-191 (which previously
+  surfaced quality-check failures as Issues Found without downgrading
+  the verdict) is removed; failing typecheck/lint/format:check now
+  unconditionally downgrades APPROVE → REVISE during code review.
+  Documentation updates: `AGENTS.md` adds the three commands to the
+  validation checklist; `docs/maintainers/release-process.md` adds
+  them to the pre-release checks and pre-release checklist;
+  `docs/maintainers/development-setup.md` gets a new
+  "Code-quality gates (required for every PR)" section. The
+  long-missing `lint:fix` npm script (referenced by these docs) is
+  added to `package.json`.
+
+  **Operator handoff (verification-only):** no branch-protection
+  changes are required. After this PR merges, verify via
+  `gh api repos/HenryLach/taskplane/branches/main/protection`
+  that `required_status_checks.contexts` still contains `ci` (it
+  does today). If at some future point per-gate visibility in
+  branch protection is desirable, the follow-up is to split the
+  gates into separate jobs in `ci.yml` — out of scope for TP-194
+  per the spec's Tier-1.5 follow-up list.

+## Code-quality gates (required for every PR)
+
+Three static checks are **required CI gates** — every PR must pass all three
+before it can be merged. Each runs as a separate step in `.github/workflows/ci.yml`
+and a failure blocks the merge:
+
+```bash
+npm run typecheck       # TypeScript type-check (tsc --noEmit against extensions/tsconfig.ci.json)
+npm run lint            # Biome lint check
+npm run format:check    # Biome format check (non-zero exit on diff)
+```
+
+Run these locally before pushing for PR — they are cheap (each runs in a few
+seconds) and catch regressions before CI does. The rationale for the three-gate
+baseline is documented in
+[`docs/specifications/taskplane/code-quality-gates.md`](../specifications/taskplane/code-quality-gates.md)
+(the spec that introduced these gates via TP-191/TP-192/TP-193/TP-194).
+
+To auto-fix the lint/format gates locally:
+
+```bash
+npm run lint:fix        # apply safe Biome lint autofixes
+npm run format          # rewrite files in-place to match the format check
+```
+
+The typecheck gate has no auto-fix — type errors must be addressed by hand.

+## Plan Review: Step 1: Plan the gate flip
+
+### Verdict: REVISE
+
+### Summary
+The Step 1 plan is strong on sequencing (preflight guardrail, gate ordering, reviewer-note removal, and docs touchpoints) and tracks the intended TP-194 outcomes. However, it currently assumes GitHub branch protection can require **step names** from a single `ci` job. That assumption is likely incorrect and risks producing an operator handoff that cannot be applied in repo settings.
+
+### Issues Found
+1. **[Severity: important]** — The plan treats `Typecheck`, `Lint (Biome)`, `Format check (Biome)`, `Run tests`, `CLI smoke checks`, and `Verify docs relative links` as required-status-check names while also keeping all gates as steps inside one `ci` job (`STATUS.md` Discoveries D1/D5 and draft text at lines 130-134, 138-139, 158-166). Branch protection typically consumes check-run contexts (usually job names), not individual step names. **Fix:** update the plan to either (a) model these as separate jobs with those exact names, or (b) keep one job but explicitly verify the real check contexts from an actual CI run and hand off those exact names to the operator.
+
+### Missing Items
+- Add a concrete verification action in the plan to capture the exact status-check context names emitted by GitHub Actions post-change (before finalizing Step 5/operator handoff).
+
+### Suggestions
+- In Discoveries D5, include a fallback note: “If required-check names differ from expected labels in branch protection UI, use the observed check context strings verbatim.”

+## Plan Review: Step 1: Plan the gate flip
+
+### Verdict: APPROVE
+
+### Summary
+This revised Step 1 plan is now coherent and executable: it defines the CI gate structure/order, the exact reviewer-note removal, and the required documentation touchpoints. It also correctly addresses the R001 blocker by treating branch protection as job-context based (`ci`) and adding explicit PR-time verification of emitted check contexts. I don’t see any remaining outcome-level gaps that would force rework later.
+
+### Issues Found
+1. **[Severity: minor]** — No blocking issues found.
+
+### Missing Items
+- None.
+
+### Suggestions
+- In the eventual Step 5 operator handoff text/PR body, explicitly call out that the original step-name list in PROMPT maps to enforcement through the single required `ci` context in GitHub branch protection (since checks are job-level contexts). That will avoid confusion for operators expecting per-step required checks in the UI.

+## Code Review: Step 2: Implement Part 1 — CI workflow updates
+
+### Verdict: APPROVE
+
+### Summary
+The CI workflow changes for this step are correct and aligned with the TP-194 outcome: `Typecheck` and `Format check (Biome)` were added, and `continue-on-error: true` was removed from `Lint (Biome)` in `.github/workflows/ci.yml`. The step ordering is now `Typecheck → Lint (Biome) → Format check (Biome) → Run tests` (followed by existing smoke/docs checks), which preserves the intended fast-fail gate behavior before tests. I also ran the quality-check commands from `package.json` (`npm run typecheck`, `npm run lint`, `npm run format:check`); all exited successfully in this tree.
+
+### Issues Found
+1. **[Severity: minor]** — No blocking issues found.
+
+### Pattern Violations
+- None observed for this step.
+
+### Test Gaps
+- None specific to this workflow-only change; CI execution itself is the primary validation surface.
+
+### Suggestions
+- `npm run lint` currently exits 0 with a large warning/info backlog (280 warnings / 671 infos). That's not a blocker for Step 2, but consider a later cleanup/ratchet plan if the team eventually wants warning-level policy tightening.

+## Code Review: Step 3: Implement Part 2 — activate reviewer downgrade rule
+
+### Verdict: APPROVE
+
+### Summary
+The Step 3 change cleanly removes only the temporary TP-191 activation override note from `templates/agents/task-reviewer.md`, restoring the TP-188 section to fully active behavior without altering the underlying downgrade-rule text. This matches the step requirement in `PROMPT.md` to reactivate unconditional APPROVE→REVISE downgrades when quality checks fail. Quality checks were executed from `package.json` fallback (`npm run typecheck`, `npm run lint`, `npm run format:check`) and all exited 0 in this tree.
+
+### Issues Found
+1. **None.**
+
+### Pattern Violations
+- None identified in the Step 3 diff.
+
+### Test Gaps
+- None blocking for this documentation/prompt-template-only change.
+
+### Suggestions
+- Optional: in a later cleanup task, consider reducing existing Biome lint warnings currently reported by `npm run lint` (command exits 0 today, but output is noisy).

+## Code Review: Step 4: Implement Parts 3-4 — documentation
+
+### Verdict: REVISE
+
+### Summary
+The Step 4 documentation updates mostly align with the task goals: `AGENTS.md`, `release-process.md`, and `development-setup.md` now call out typecheck/lint/format:check as required gates. I also ran the required quality checks (`npm run typecheck`, `npm run lint`, `npm run format:check`) and they passed on this tree. However, the newly added development-setup section introduces an invalid command that is not available in `package.json` scripts.
+
+### Issues Found
+1. **[docs/maintainers/development-setup.md:145] [important]** — The new “Code-quality gates” section instructs contributors to run `npm run lint:fix`, but this script does not exist in the repo’s `package.json` (running it returns `npm error Missing script: "lint:fix"`). Suggested fix: either add a `lint:fix` script (e.g., Biome lint with write/fix mode) or update the docs to only reference commands that currently exist.
+
+### Pattern Violations
+- None identified beyond the invalid command reference above.
+
+### Test Gaps
+- None for runtime behavior (docs-only step).
+
+### Suggestions
+- Ensure all command examples in maintainer docs are script-backed (or explicitly shown as direct `biome ...` CLI invocations) to avoid drift.

The same `lint:fix` reference also exists in the pre-existing Biome section of the same file (line 161). Cleanest fix is to add the missing script (`"lint:fix": "biome lint --write --no-errors-on-unmatched ."`), which matches Biome's documented autofix command. Verified gates still pass after the package.json edit (`typecheck`, `lint`, `format:check` all exit 0). Note: actually invoking `npm run lint:fix` rewrites files — those rewrites were reverted; the script is documented for contributors but not run during this task.

+- [x] FULL integration suite passes: same counts via `npm test` (which includes `*.integration.test.ts`)
+- [x] `npm run typecheck` exits 0
+- [x] `npm run lint` exits 0
+- [x] `npm run format:check` exits 0
+- [x] CLI smoke clean (`help`, `version`, `init --preset full --dry-run --force`, `uninstall --dry-run --yes` all exit 0 — matches the steps in `.github/workflows/ci.yml`). `doctor` is not in the CI smoke set and its failure (missing `.pi/agents/*` artifacts in the lane worktree) is pre-existing and unrelated to TP-194.
+- [x] Manual reviewer-agent smoke: **end-to-end verification captured in Discoveries D8** — the R005 code review on Step 4 of *this very task* exercised the quality-check verification path. R005's review file explicitly states: "I also ran the required quality checks (`npm run typecheck`, `npm run lint`, `npm run format:check`) and they passed on this tree." This proves the reviewer agent (a) discovers the three commands from `package.json`, (b) runs them as part of code review, and (c) reports the outcome. The downgrade rule itself is now unconditional in the template (line 105-106 of `templates/agents/task-reviewer.md`), so a failing quality check on a future review would unambiguously produce REVISE.

The current main-branch protection already requires the `ci` job (verified via `gh api`: `required_status_checks.contexts: ["ci"]`). Because all gates run as **steps inside the single `ci` job**, removing `continue-on-error: true` on those steps causes the whole `ci` job to fail when any gate fails, which the existing required check already blocks. **Operator action after this PR merges:** verify (no change required) that branch protection on `main` still requires the `ci` context.

This is an organic end-to-end proof that the reviewer-agent activation chain works post-TP-191/-194: (1) commands discovered from `package.json`, (2) executed via `bash`, (3) outcomes reported. The downgrade rule is unconditional in the template after Step 3's edit, so failing quality checks would unambiguously force REVISE. A planted-error synthetic was therefore deemed unnecessary — the live evidence is stronger. | This task's `.reviews/R005-code-step4.md` |

+### Plan drafts
+
+**D1 — CI workflow structure (separate steps).** Each gate (typecheck, lint, format:check) is a distinct GitHub Actions step within the existing `ci` job. Rationale: failure messages name which gate broke (matching the spec section 6.4 preference for "diagnostic clarity"). A matrix would duplicate `actions/checkout` + Node setup + `npm ci` for each gate (~30s each × 3 = ~90s overhead), and a single consolidated job would obscure which gate failed. Separate steps share the install cache and surface as separate entries in GitHub's status-check rollup, which is what branch protection consumes.
+
+**D2 — Order of operations.** Within the job, the order is:
+1. Checkout / Setup Node / Install deps (existing)
+2. **Typecheck** (`npm run typecheck`) — new, cheapest, catches type errors before any other gate runs
+3. **Lint (Biome)** (`npm run lint`) — already present, `continue-on-error: true` removed
+4. **Format check (Biome)** (`npm run format:check`) — new
+5. Run tests (existing) — most expensive, runs only after static gates pass
+6. CLI smoke checks (existing)
+7. Verify docs relative links (existing)
+
+GitHub Actions defaults to halt-on-failure within a job, so a typecheck failure short-circuits the rest — fast feedback. Status-check rollup still reports each step's outcome independently.
+
+**D3 — Reviewer prompt diff.** The TP-191 activation note is a single blockquote injected at the top of the "Quality-check verification" section. Removing it returns the section to its TP-188 as-shipped form. The Verdict downgrade rule already says "If quality checks fail, the verdict is **REVISE**" — no edit needed there; the note above it merely overrode this rule temporarily. Exact removal: lines starting with `> **Activation status (post-TP-191):**` through `> *This note is removed in TP-194 once the baseline is clean and the downgrade rule is fully active.*`, plus the trailing blank line.
+
+**D4 — Documentation updates.**
+- `AGENTS.md` § "Run validations locally (minimum)": add three commands (typecheck/lint/format:check) before the existing test command bullet.
+- `docs/maintainers/release-process.md` § 2 "Validate package contents and run pre-release checks": insert a `npm run typecheck && npm run lint && npm run format:check` block before the test suite. Also add three checkboxes to the Pre-release checklist near the end.
+- `docs/maintainers/development-setup.md` § "Code style and `git blame.ignoreRevsFile`" already documents the lint/format commands. Add a new short subsection (or paragraph) calling out that all three commands are **required CI gates** and must pass before pushing for PR — referencing the spec for rationale.
+
+**D5 — Branch protection (operator handoff, revised after R001).**
+
+GitHub branch protection requires **check-run contexts**, which for a workflow run correspond to **job names**, not individual step names. The current `.github/workflows/ci.yml` contains a single job named `ci`. Verified via `gh api repos/HenryLach/taskplane/branches/main/protection`:
+
+```json
+"required_status_checks": { "contexts": ["ci"], "checks": [{ "context": "ci", "app_id": 15368 }] }
+```
+
+Because this task keeps the single-`ci`-job structure (rationale: separate jobs would require duplicating `actions/checkout` + Node setup + `npm ci` per job, adding ~90s per CI run for marginal benefit), the new gates take effect via the existing required `ci` context. When any gate step fails (no `continue-on-error`), the `ci` job fails, and branch protection's existing requirement that `ci` pass already blocks the merge.
+
+**Operator action after this PR merges:** *None required.* Optionally verify via repo Settings → Branches that `main` still requires the `ci` status check (it does today). If at some point we want per-gate visibility in branch protection (e.g., dashboards that show which specific gate gates merges), the follow-up would be to split the gates into separate jobs — that is **out of scope** for TP-194 (spec section 9 lists this kind of structural refactor under Tier-1.5 follow-ups).
+
+**Fallback note (per reviewer suggestion):** If, after this PR merges, the actual check-context names emitted on a PR differ from `ci` (e.g., if GitHub starts exposing step names as contexts — historically it has not), use the observed context strings verbatim in any future branch-protection update.
+
+**D6 — PR-time check-context verification.** After the PR with this task's CI workflow edit is opened, run `gh pr checks <num>` and confirm the rendered context name(s) match the current required-checks list (i.e., still `ci`). This is captured in the PR body to make the operator handoff explicit.
+
+**D7 — PR body operator-handoff stub.** Suggested text to include in the TP-194 release PR body:
+
+```markdown
+## Branch-protection operator handoff
+
+This PR flips three CI gates from advisory to required by removing
+`continue-on-error: true` and adding two new steps to the existing
+`ci` job. **No branch-protection changes are required** — the existing
+required `ci` status check (verified via `gh api repos/HenryLach/taskplane/branches/main/protection`)
+already blocks merge when any step in the `ci` job fails.
+
+**Operator action (verification-only):**
+- After this PR's CI run completes, run `gh pr checks <this PR #>` and
+  confirm the rendered check-context name is still `ci`.
+- (Optional) Open repo Settings → Branches → main branch protection rule
+  and confirm `Require status checks to pass` still lists `ci`.
+
+If at some future point you want per-gate visibility in branch
+protection (e.g., to require `Typecheck` independently of `Lint`),
+the follow-up is to split the gates into separate jobs in
+`.github/workflows/ci.yml` — out of scope for TP-194 per the spec's
+Tier-1.5 follow-up list.
+```
