+Implemented, reviewed, merged, and validated.
+
+Summary:
+- Clarified Panel focus and composer key handling.
+- Moved Panel target switching from `Ctrl+T` to `Tab`; `Ctrl+T` no longer switches Panel targets or appears in Panel help/actionbar as target switch.
+- Added shared `composer_keys` handling used by normal TUI and workspace panel composer editing.
+- Preserved bare-letter typing behavior; letters such as `j/k/o/r` enter composer text rather than acting as shortcuts.
+- Made focus/Enter behavior clearer for global composer, selected row, and item action states.
+- Fixed selected Ticket row + non-empty global composer ambiguity: actionbar/status now describes composer-target Enter behavior rather than row action.
+- Added regression tests and updated Panel canonical-ID display tests.
+
+Implementation:
+- Coder commits: `20f06b3 tui: clarify panel focus and composer keys`, `573b02f tui: clarify panel composer enter hints`
+- Reviewer approved after fix loop.
+- Merge commit: `57ed405 merge: improve panel composer keys`

 Residual risk: no blocking risk. Panel has no active completion popup/source yet, so Tab completion priority remains verified at the caller-boundary design level rather than by an active completion UI scenario.
