-# Task: FN-4137 - Add markdown rendering toggle to Task Review tab
-
-**Created:** 2026-05-09
-**Size:** S
-
-## Review Level: 1 (Plan Only)
-
-**Assessment:** Retry-only coordination spec. The implementation work is already committed on `fusion/fn-4137`; this retry exists only to verify and deliver the branch without redoing the feature work.
-**Score:** 2/8 — Blast radius: 1, Pattern novelty: 0, Security: 0, Reversibility: 1
-
-## Mission
-
-Ship the already-implemented Task Review markdown toggle work from branch `fusion/fn-4137` without re-implementing it.
-
-The branch already contains these committed changes:
-- `75e2775c7` — `feat(FN-4137): complete Step 1 — add review markdown toggle`
-- `b07ec4dcc` — `feat(FN-4137): complete Step 4 — document review markdown toggle`
-- `16b16232b` — `fix(FN-4137): address Frontend UX Design review — unwrap body from checkbox label, soften mobile actions row`
-
-This retry is limited to verification, merge-conflict cleanup if needed, and delivery.

-## Dependencies
-
-- None
-
-## Context to Read First
-
-- `packages/dashboard/app/components/TaskReviewTab.tsx`
-- `packages/dashboard/app/components/TaskReviewTab.css`
-- `packages/dashboard/app/components/__tests__/TaskReviewTab.test.tsx`
-- `.changeset/FN-4137-review-markdown-toggle.md`
-- `AGENTS.md` → "Dashboard UI Styling Guide"
-
-## File Scope
-
-Verification only. Do not re-edit the implemented FN-4137 feature files unless resolving a main-merge conflict introduced during retry.
-
-## Steps
-
-### Step 1: Verify the existing branch contents
-
-- [ ] Confirm `fusion/fn-4137` contains the markdown toggle implementation from `75e2775c7`.
-- [ ] Confirm `TaskReviewTab.tsx` keeps the checkbox/summary metadata inside the label but renders the markdown/plain body outside the label so body clicks do not toggle selection.
-- [ ] Confirm `TaskReviewTab.css` includes the relaxed mobile actions layout (wrapping actions row; no forced equal-width three-button row on mobile).
-- [ ] Confirm `packages/dashboard/app/components/__tests__/TaskReviewTab.test.tsx` includes the FN-4137 regression test covering markdown-body clicks not toggling the checkbox.
-- [ ] Confirm `.changeset/FN-4137-review-markdown-toggle.md` exists.
-- [ ] **Do NOT re-edit these files during this step.**
-
-### Step 2: Testing & Verification
-
-- [ ] Run `pnpm --filter @fusion/dashboard test`.
-- [ ] Run `pnpm lint`.
-- [ ] Run `pnpm test`.
-- [ ] Run `pnpm build`.
-- [ ] Fix only failures caused by merge conflicts or retry-specific integration drift from `main`; do not refactor.
-
-### Step 3: Documentation & Delivery
-
-- [ ] Confirm the existing changeset file still exists and is staged for merge via branch history.
-- [ ] No additional docs are required.
-- [ ] Hand off for merge/delivery.
-
-## Documentation Requirements
-
-**Must Update:**
-- None, unless conflict resolution requires updating an already-touched FN-4137 file.
-
-**Check If Affected:**
-- None.
-
-## Completion Criteria
-
-- [ ] Existing FN-4137 implementation remains intact on `fusion/fn-4137`
-- [ ] Dashboard tests pass
-- [ ] Workspace lint, test, and build pass
-- [ ] Changeset file `.changeset/FN-4137-review-markdown-toggle.md` remains present
-- [ ] Task is delivered without redoing the original implementation steps
-
-## Git Commit Convention
-
-- Preserve existing FN-4137 history where possible
-- Any conflict-resolution follow-up commit must include the task ID: `fix(FN-4137): ...`
-
-## Do NOT
-
-- Do NOT redo Step 1 of the original prompt.
-- Do NOT re-implement the markdown toggle.
-- Do NOT refactor `TaskReviewTab` beyond conflict-resolution needs.
-- Do NOT add a second changeset.
-- Do NOT remove the existing regression coverage.
-
-## Changeset Requirements
-
-Use the existing `.changeset/FN-4137-review-markdown-toggle.md`. Do not add another changeset unless the existing file has been lost and must be restored exactly.
