# Interactive recipient-aware message composer
Make bare `@` safe for ordinary unquoted prose while keeping the selected
recipient visible and switchable.
## Required operator contract
Running `@` without arguments opens an inline composer whose prompt is the
selected repository, for example `@flex-auth: `. Plain text is read directly
from the terminal, so apostrophes and other shell punctuation do not require
quoting. Tab cycles through the other repository windows in the managed
session, preserving the draft. Enter queues the message and Ctrl-C cancels it.
The initial recipient is the latest durable inbound sender when available. If
there is no message history, use the first other repository in the session.
The existing `@ MESSAGE` shorthand remains a non-interactive fast path and
retains normal shell quoting rules.
## Expose session recipients to the generic command
```task
id: TAMQ-WP-0009-T01
status: done
priority: high
state_hub_task_id: "320e4c7c-9c44-5023-8c60-7b270a0276f5"
```
Encode the addressable repository list in the tamq-owned generic `@` shim,
without changing shell configuration or trusting arbitrary repository names.
Exclude the current repository from the interactive recipient cycle.
## Implement the terminal composer
```task
id: TAMQ-WP-0009-T02
status: done
priority: high
state_hub_task_id: "6973e046-f8b3-50d1-958b-4216af656624"
```
Add a small terminal-local editor that displays `@recipient: `, accepts literal
UTF-8 prose, handles backspace and Ctrl-U, cycles recipients on Tab without
losing the draft, submits on Enter, and restores terminal settings on every
exit path. Ctrl-C cancels without queuing a message.
## Prove and document the interaction
```task
id: TAMQ-WP-0009-T03
status: done
priority: high
state_hub_task_id: "85b8bb9f-cf0d-5d95-9598-1cec8449ac17"
```
Cover recipient ordering, shim metadata, non-TTY rejection, punctuation,
editing and cancellation with pseudo-terminal tests. Run the full checks,
install the build, exercise the composer in the live two-window session, and
update README and SCOPE.
## 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.
