# Review by Linus Torvalds (Round 1)

## Review Complete — Linus Torvalds, Round 5

**2683/2683 tests passing.** All 15 functional requirements are implemented. The architecture decisions are correct.

VERDICT: **request-changes**

FINDINGS:
- **[src/colonyos/pr_sync.py]**: `_get_current_failures` does a linear scan with magic number `999999` instead of a direct SQL query — write `SELECT sync_failures FROM pr_outcomes WHERE pr_number = ?`
- **[src/colonyos/pr_sync.py]**: Two separate `OutcomeStore` instances opened for one logical operation — pass the store through to `_sync_single_pr` instead of creating a new one
- **[src/colonyos/pr_sync.py]**: `_check_merge_state` makes redundant `gh pr view` calls when `mergeStateStatus` is already fetched by outcome polling — use the cached data from `OutcomeStore`
- **[src/colonyos/pr_sync.py]**: Missing escalation notification when a PR hits `max_sync_failures` (FR-10 explicitly requires a "final escalation notification")
- **[src/colonyos/pr_sync.py]**: Manually constructs worktree paths instead of using the existing `WorktreeManager` class that the PRD explicitly calls for (FR-4)

SYNTHESIS:
The overall architecture is sound — the right decisions were made at the design level (merge not rebase, worktree isolation, opt-in, 1-per-tick). The code reads cleanly top to bottom, test coverage is thorough (47 new tests), and nothing will crash the daemon. But there are five concrete issues. Three are about unnecessary duplication and waste (linear scan with a magic number, duplicate DB connections, redundant API calls), one is a missing PRD requirement (escalation notification at max failures), and one is ignoring the existing `WorktreeManager` abstraction the PRD explicitly specifies. None are hard to fix — they're the kind of sloppy shortcuts you get from writing code in one pass without checking what the codebase already provides. Fix these five things and it's a clean approve.
