## Findings

- [src/colonyos/cli.py]: The `watch()` function has become a 600+ line monstrosity with deeply nested closures, inner classes, and nonlocal state. `QueueExecutor` is an inner class that captures variables from the enclosing scope (`_slack_client`, `_check_budget_exceeded`, etc.) — this is a code smell. The class should be extracted to module level and receive its dependencies explicitly. The current structure makes the code nearly impossible to test in isolation and painful to read.

- [src/colonyos/cli.py]: `_execute_item()` and `_execute_fix_item()` share about 70% of their code — the Slack client wait, UI factory construction, status bookkeeping, cost tracking, and result posting are all copy-pasted. This is the kind of duplication that breeds bugs: fix a race condition in one, forget the other. Extract the common skeleton.

- [src/colonyos/orchestrator.py]: `run_thread_fix()` has 5 separate early-return failure paths that all do the same `log.status = RunStatus.FAILED; log.mark_finished(); _save_run_log(); return log` dance. This is begging for a context manager or a single cleanup path. You wrote the same 4 lines five times — that's not engineering, that's copy-paste.

- [src/colonyos/orchestrator.py]: The `run()` function now has a `try/finally` block that stashes uncommitted changes and restores the original branch. This is good defensive programming but the stash is a named stash (`colonyos-{branch_name}`) that is never explicitly popped or cleaned up. Over time this accumulates orphaned stashes. At minimum, document this behavior; ideally, clean up on success.

- [src/colonyos/slack.py]: `should_process_thread_fix()` iterates over the full `queue_items` list linearly for every threaded message. For a watch process running for hours with hundreds of completed items, this is O(n) per event. A `dict[str, QueueItem]` keyed by `slack_ts` would make this O(1). Not critical now, but worth noting.

- [src/colonyos/slack.py]: The `triage_message()` function does a lazy import of `run_phase_sync` and `Phase` inside the function body. I understand this is to avoid circular imports, but it's a sign the module boundaries are wrong. The triage logic should live in its own module, not in `slack.py`.

- [src/colonyos/models.py]: `QueueItem` now has 18 fields. The `to_dict()` / `from_dict()` are manually maintained dictionaries that must stay in sync with the dataclass fields. This is fragile — one added field without updating both methods means silent data loss. Consider using `dataclasses.asdict()` or at least add a test that verifies round-trip fidelity for all fields.

- [src/colonyos/orchestrator.py]: `run_thread_fix()` skips the Verify phase entirely — the PRD says "Runs Verify phase (test suite)" (FR-7). The implementation goes straight from Implement to Deliver. This is a functional gap.

- [src/colonyos/instructions/thread_fix.md]: Step 2 tells the agent to "Ensure you are on branch `{branch_name}`" but the orchestrator already checks out the branch before invoking the agent. This is harmless but misleading — the instruction implies the agent needs to do something that's already done.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/orchestrator.py]: FR-7 requires Verify phase in thread-fix pipeline but it is skipped — only Implement and Deliver run
- [src/colonyos/cli.py]: `_execute_item()` and `_execute_fix_item()` are ~70% duplicated code — extract common execution skeleton
- [src/colonyos/orchestrator.py]: Five identical early-return failure paths in `run_thread_fix()` — extract to single cleanup path
- [src/colonyos/orchestrator.py]: Named git stash (`colonyos-{branch_name}`) in `run()` finally block is never cleaned up, accumulating orphaned stashes
- [src/colonyos/slack.py]: Linear scan of queue_items in `should_process_thread_fix()` is O(n) per event — use a dict for O(1) lookup
- [src/colonyos/cli.py]: `QueueExecutor` inner class captures enclosing scope variables — should be extracted to module level

SYNTHESIS:
The implementation covers 20 of 21 functional requirements and the overall architecture is sound — the thread-fix detection, queue integration, and sanitization pipeline are all correct. Tests are comprehensive (498 passing) and cover the important edge cases. However, the missing Verify phase is a clear functional gap against the PRD (FR-7 explicitly says "Runs Verify phase (test suite)"). The code quality is mediocre: the `watch()` function is a 600-line closure zoo, there's significant duplication between `_execute_item` and `_execute_fix_item`, and `run_thread_fix()` has five copy-pasted failure paths. The data structures are right (QueueItem extensions, fix_rounds tracking, parent_item_id), but the code that operates on them needs a cleanup pass. Fix the missing Verify phase and deduplicate the executor methods, then this is ready to ship.
