+## Completion evidence
+
+- `make check`: 109 tests passed, including pseudo-terminal coverage for
+  literal apostrophes, recipient cycling with draft preservation, UTF-8-aware
+  backspace, Ctrl-U, Ctrl-C, and terminal restoration.
+- Coverage: 76% overall and 76% for the new composer module.
+- `make install`: installed `tmux-amq==0.1.0` and refreshed the live session's
+  tamq-owned command shims.
+- Live `flex-auth` composer: delivered `What's up? WP0009-live-smoke` without
+  shell quoting, then retained `cycle-draft` while Tab changed the visible
+  recipient from `@audit-core: ` to `@railiance-platform: `. Ctrl-C cancelled
+  that draft. The controlled smoke message was acknowledged; existing user
+  messages were not.
