# Delivery reliability and practical integration evidence

Close the reliability gaps found during the 2026-08-24 intent and usability
assessment before treating tmux-amq as an unattended local transport or as a
stable coordination-engine dependency.

## Enforce bounded delivery attempts

```task
id: TAMQ-WP-0003-T01
status: todo
priority: high
state_hub_task_id: "52c43745-5c28-599e-b74c-0386d5b51e68"
```

Persist attempt counts and failure reasons, apply the selected policy profile's
retry cap, define lease-expiry behavior, and introduce an inspectable terminal
failure state. Prove restart-safe behavior and avoid tight retry loops.

## Enforce acknowledgement semantics

```task
id: TAMQ-WP-0003-T02
status: wait
priority: high
state_hub_task_id: "ff88d6c9-f4d7-52c7-9645-7c3a7a34ccb4"
```

Make `delivery_ack_mode` control whether injection completes delivery or waits
for explicit recipient acknowledgement. Specify timeout, redelivery, duplicate,
and late-acknowledgement behavior. This task follows the state model from T01.

## Add real tmux and PTY lifecycle coverage

```task
id: TAMQ-WP-0003-T03
status: done
priority: high
state_hub_task_id: "9a3d84b4-55a5-5d18-b4ee-99ac4f111875"
```

Exercise a real tmux server, managed windows, control-mode injection, `tamq tap`,
service shutdown, endpoint disappearance, and restart recovery without starting
an external coding agent. Keep fast unit tests while adding a bounded integration
suite.

Completed with a real isolated-tmux PTY fixture that proves initial dimensions,
`SIGWINCH` resize propagation, raw mouse-sequence forwarding without newline
buffering, and bounded cleanup. The installed-package lifecycle smoke now also
proves service shutdown/restart, stable pane reuse, disappeared-session endpoint
retirement, and clean recovery into a new tmux instance. The PTY proxy restores
terminal state and forwards termination signals; `--no-service` bypasses the tap
entirely as documented.

## Align CI and operator documentation

```task
id: TAMQ-WP-0003-T04
status: wait
priority: medium
state_hub_task_id: "44939829-a52e-582a-b06b-60337b36080e"
```

Run the integration suite in Forgejo CI with explicit tmux and gita setup. Update
README claims about retries, acknowledgement, prerequisites, and maturity from
verified behavior. This task follows T01-T03.
