+Implemented, reviewed, merged, and validated.
+
+Summary:
+- Added persistent TUI composer recall history per workspace.
+- Stores history under the user data dir at `composer-history/workspaces/<workspace-label>-<fnv64-key>/history.json`, not under workspace `.yoi/`.
+- Stores workspace metadata and typed `Segment` vectors, not flattened strings.
+- Persists only non-blank submissions, suppresses consecutive duplicates, and bounds history to 30 entries per workspace.
+- Preserves TUI-local/non-destructive recall semantics: recall does not mutate Pod protocol, worker history, session transcript, model context, or conversation state until explicit submit.
+- Corrupt history files fall back to empty history with a bounded generic warning.
+
+Implementation:
+- Coder commit: `64b7ff7 tui: persist composer history`
+- Reviewer approved with no blocking findings.
+- Merge commit: `b616420 merge: persist tui composer history`
+
+Validation after merge:
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`
+- `cargo check --workspace`
+- `nix build .#yoi`

 - Broader `cargo test -p tui` still has a pre-existing unrelated failure in `multi_composer_target_switch_preserves_typed_text`; this implementation did not modify `multi_pod.rs`.
 - Final merge/close/cleanup is intentionally not performed here without explicit merge approval.
