 Clear the mechanical leftovers flagged in the audit's "Proposed disposition (next steps)" — short, low-risk edits that should land together so reviewers can scan one PR for stale prose drift.
 
 **Action Items:**
-- [ ] Finish the truncated comment at `src/detail/webserver_register.cpp:344-349`. The TASK-029 block comment ends mid-sentence (`"…keeps working at the daemon level, but"` then closing brace). Either complete the sentence with the original intent (reconstruct from git history or surrounding code) or rewrite the comment to stand on its own.
-- [ ] Remove the two orphan comment fragments at `src/webserver.cpp:503-504` (leftover from removed logic).
-- [ ] Update the stale `XFAIL_TESTS` comment block at `test/Makefile.am:67-74` to reflect that `header_hygiene` was removed when TASK-020 landed (cross-referenced at lines 532-535 in the same file).
-- [ ] Drop the stale `RELEASE_NOTES.md) continue ;;  # created by TASK-042, not yet present` line at `scripts/check-readme.sh:273` — TASK-042 has shipped.
