+Merged and closed.
+
+Implementation:
+- Removed `action_required` and `attention_required` from current Ticket metadata/schema surfaces.
+- Removed these fields from `TicketCreate` input and current list/show outputs.
+- Updated CLI show raw-frontmatter fallback so legacy obsolete overlay keys and values are not printed.
+- Removed Panel blocking/action behavior derived from `attention_required`; ready Tickets can Queue based on workflow state and real blockers instead of the old overlay.
+- Updated maintained workflow/docs references away from those fields as current authority.
+- Added obsolete-field diagnostics/regression coverage.
+
+Commits:
+- `3afdd89 ticket: remove action attention fields`
+- `94db2dc fix: hide obsolete ticket fields in cli show`
+- merge: `6f36c93 merge: remove ticket attention fields`
+
+Review:
+- Initial review requested the CLI show legacy fallback fix.
+- Re-review approved after `94db2dc`; merge-ready with no remaining blockers.

 - No branch-specific residual risk found. Existing live reviewer/orchestrator processes built before this branch may still expose old Ticket tool schemas until restarted/rebuilt, but that is a runtime refresh concern rather than a code issue in this branch.
