**Round**: 1

## Checklist Assessment

### Completeness
- [x] FR-1: Verify phase inserted between Learn and Deliver in `_run_pipeline()`
- [x] FR-2: Verify-fix loop with configurable `max_fix_attempts`
- [x] FR-3: Hard-block delivery on persistent failure via `_fail_run_log()`
- [x] FR-4: Budget guard before each verify and fix iteration
- [x] FR-5: `VerifyConfig` dataclass + `phases.verify` in `PhasesConfig` + DEFAULTS
- [x] FR-6: `verify.md` and `verify_fix.md` instruction templates created
- [x] FR-7: Resume support — `_compute_next_phase` routes `decision → verify → deliver`
- [x] FR-8: Heartbeat touch + UI phase header before verify
- [x] FR-9: Thread-fix verify flow unchanged (no modifications to existing thread-fix code)

### Quality
- [x] All 474 tests pass (confirmed via `pytest`)
- [x] No linter errors introduced
- [x] Code follows existing patterns (budget guard, heartbeat, `_append_phase`, `_make_ui`)
- [x] No unnecessary dependencies added
- [x] No unrelated changes (all diffs are verify-related)

### Safety
- [x] No secrets or credentials in committed code
- [x] No destructive operations without safeguards
- [x] Error handling present (budget exhaustion, fix agent failure, empty verify output)

## Findings

### Critical

- **[src/colonyos/orchestrator.py: `_verify_detected_failures()`]**: This function is the single most critical piece of logic in the feature — it decides whether to block delivery or proceed — yet it has **zero dedicated unit tests**. The heuristic is fragile: the word "error" appears in perfectly valid pytest output ("0 errors"), and "passed" appears alongside failures ("3 passed, 2 failed"). The current logic checks pass patterns first then falls through to failure patterns, but "passed" would match "3 passed, 2 failed" and the `has_failure` check would catch it... except `"failed"` is in both `pass_patterns` (via absence check) and `failure_patterns`. Edge cases: (1) "passed" + "error" in tracebacks = false negative; (2) output containing only "error" in a module name = false positive; (3) `cargo test` output like "test result: ok. 50 passed; 0 failed" triggers the `"passed"` pass pattern but also contains `"failed"` → correctly detected as pass due to `has_failure` check for `"0 failed"` wait no, `"failed"` IS in `failure_patterns` so `has_failure = True` → falls through to failure check → returns True (false positive!). **This is a real bug**: any output containing the literal word "failed" even in "0 failed" will be detected as a failure. This means `cargo test` and `pytest` outputs with "0 failed" will always be flagged as failures.

### Moderate

- **[src/colonyos/orchestrator.py: resume mapping]**: `_compute_next_phase` has no mapping for `"learn"`. If a run fails during verify, the last successful phase is `"learn"`, and `_compute_next_phase("learn")` returns `None` — meaning the run cannot be resumed. The test at line 518 in `test_verify_phase.py` acknowledges this with a lengthy comment and works around it by manually constructing `ResumeState` with `last_successful_phase="decision"`. This is a real gap: a run that fails during verify cannot be auto-resumed via `prepare_resume()`.

- **[src/colonyos/orchestrator.py: `_SKIP_MAP["verify"]`]**: The verify skip set includes `"verify"` itself, which means if resuming from a successful verify phase, verify would be skipped. But the `_compute_next_phase("verify")` returns `"deliver"`, so this skip entry would only matter for the case where we resume from verify but the verify wasn't the failing phase — which is a logically inconsistent state. Not harmful, but indicates the resume semantics weren't fully thought through.

- **[src/colonyos/orchestrator.py: verify-fix uses `Phase.FIX`]**: The verify-fix agent reuses `Phase.FIX` rather than having its own phase enum value. This means in the run log, you can't distinguish between a review-fix and a verify-fix — they both appear as `Phase.FIX`. At 3am debugging a broken run, this ambiguity makes it harder to reconstruct what happened. The PRD doesn't explicitly require a separate phase value, but the "audit boundary" argument in the PRD's Technical Considerations section implies distinguish-ability matters.

### Minor

- **[src/colonyos/config.py: `_parse_verify_config`]**: Validates `max_fix_attempts >= 1` but the pipeline also runs the initial verify (attempt 0) plus up to `max_fix_attempts` fix iterations, for a total of `max_fix_attempts + 1` verify executions. The naming `max_fix_attempts` is correct but could confuse operators who set it to 1 expecting only 1 total verify run (they'll get 2: initial + 1 re-verify after fix). This is consistent with `max_fix_iterations` elsewhere so it's fine, just noting it.

- **[src/colonyos/instructions/verify_fix.md]**: Line "Commit all fixes on branch `{branch_name}`" instructs the fix agent to commit. This is correct behavior but could be surprising if the verify-fix agent creates commits that aren't squashed — the PR will show intermediate fix commits. This matches existing fix behavior so it's consistent.

## Synthesis

This is a solid, well-structured implementation that follows the established patterns in the codebase. The config layer is clean, instruction templates are well-scoped (read-only verify vs. write-enabled fix), the budget guard mirrors the review loop, and the 474 tests all pass including 552 lines of new verify-specific tests.

However, there is one **real bug** that must be fixed before merge: `_verify_detected_failures()` will false-positive on any test output containing the literal string "failed" — including pytest's standard "0 failed" in passing runs. This means the verify phase will *always* trigger the fix loop when using pytest (which outputs "X passed, 0 failed" on success), completely undermining the feature's purpose. The function also has zero unit tests despite being the most critical decision point in the entire feature.

The resume gap (`"learn"` not in `_compute_next_phase`) is a moderate issue — it means verify failures can't be auto-resumed, which partially undermines FR-7's intent.

I'd approve this with the `_verify_detected_failures` bug fixed and basic unit tests added for that function.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/orchestrator.py]: `_verify_detected_failures()` false-positives on "0 failed" — any pytest/cargo output with passing runs will be flagged as failures because "failed" appears in the output even when prefixed by "0"
- [src/colonyos/orchestrator.py]: No unit tests for `_verify_detected_failures()` despite it being the critical pass/fail decision point
- [src/colonyos/orchestrator.py]: `_compute_next_phase` missing `"learn"` mapping means verify failures cannot be auto-resumed via `prepare_resume()`
- [src/colonyos/orchestrator.py]: Verify-fix reuses `Phase.FIX` making it indistinguishable from review-fix in run logs

SYNTHESIS:
The implementation is architecturally sound and follows established patterns well. The config layer, instruction templates, budget guards, and test coverage are all solid. However, the `_verify_detected_failures()` heuristic has a critical bug: it will false-positive on standard pytest output containing "0 failed", causing the verify-fix loop to trigger on every passing test suite. This single function is the lynchpin of the entire feature — if it misclassifies, either broken PRs ship (false negative) or every run burns budget on unnecessary fix loops (false positive). Fix the heuristic, add unit tests for it, and add `"learn"` to the resume mapping, and this is ready to ship.
