+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Track the next unresolved CodeRabbit review threads on PR #49 after commit 62ad77dc and resolve the still-valid follow-up issues while documenting stale repeats.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 All still-actionable CodeRabbit comments in the latest PR #49 round are fixed or explicitly shown stale with evidence.
+- [x] #2 Regression coverage is updated for any workflow or test changes made in this round.
+- [x] #3 Relevant verification passes for the touched workflow and prerelease test changes.
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Assessed latest unresolved CodeRabbit round on PR #49. `src/core/services/overlay-shortcut.ts` comment is stale: `registerOverlayShortcuts()` returns `hasConfiguredOverlayShortcuts(shortcuts)`, so runtime registration is not hard-coded false.
+
+Added exact, line-ending-agnostic prerelease tag trigger assertions in `src/prerelease-workflow.test.ts` and a regression asserting `bun run test:env` sits in the prerelease quality gate before source coverage.
+
+Updated `.github/workflows/prerelease.yml` quality-gate to run `bun run test:env` after `bun run test:fast`.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Assessed the latest CodeRabbit round for PR #49. Left the `overlay-shortcut.ts` thread open as stale with code evidence, tightened prerelease workflow trigger coverage, and added the missing `test:env` step to the prerelease quality gate. Verification: `bun test src/prerelease-workflow.test.ts`; `bun run typecheck`.
