## Summary

Completed Edge-native Anthropic Messages ingress, native tunneling, and the Messages-to-Chat bridge after three review loops; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G09_01.log` | `code_review_cloud_G09_01.log` | FAIL | The first attempt used an invalid active-only split dependency gate and did not implement the scoped Messages work. |
| `plan_cloud_G09_02.log` | `code_review_cloud_G09_02.log` | FAIL | The main implementation passed its regression suite, but the Chat bridge emitted buffered content after a same-frame terminal event. |
| `plan_cloud_G05_03.log` | `code_review_cloud_G06_03.log` | PASS | The bridge now stops at the first successful terminal transition, discards buffered successors, and has integrated `[DONE]` and upstream-error regressions. |

## Implementation and Cleanup

- Added canonical and compatibility Anthropic Messages surfaces with shared principal authentication, Anthropic model discovery, and count-tokens handling.
- Added selected-profile native Messages tunneling with bounded header/model rewriting and preserved response, error, SSE, and terminal semantics.
- Added Messages-to-Chat request, response, error, tool, thinking, usage, and streaming conversion.
- Closed the request-local terminal boundary so no buffered or later tunnel event can emit output after `message_stop` or `error`.
- Added integrated terminal-order regressions for same-frame `[DONE]` and upstream errors followed by late data and tunnel END.
