# Review by Linus Torvalds (Round 2)

All 2380 tests pass. Let me now write my review.

## Review — Linus Torvalds

Alright, I've read this thing top to bottom. Here's my assessment.

The good news: this is a clean, well-scoped feature. It follows existing project conventions religiously — SQLite storage, `gh` CLI subprocess calls, try/except-log-continue resilience, Rich tables for CLI output. The data structures are straightforward. The tests are comprehensive (37 new tests, all passing, full suite of 2380 green). No new dependencies. No clever abstractions. The code does what the PRD says, and it does it the simple, obvious way.

That's exactly what I want to see. Let me call out the things that are actually done right:

1. **`INSERT OR IGNORE` with `UNIQUE` on `pr_number`** — the right way to handle idempotent inserts. No TOCTOU race, no "check then insert" nonsense.
2. **Single `OutcomeStore` connection in `format_outcome_summary`** — fixed from a prior round where it was opening two connections. Good.
3. **`timeout=10` on `sqlite3.connect`** — handles concurrent daemon + orchestrator writes. Simple, correct.
4. **Parameterized SQL everywhere** — no string formatting into queries. This is table stakes, but you'd be surprised how often people screw it up.
5. **Non-blocking integration** — every call site wraps outcomes in try/except so the main pipeline never dies because of a tracking failure. This is correct. Tracking is a nice-to-have, delivery is the job.

Now the nits. These are not blocking, but I'll point them out because someone should fix them eventually:

**1. Duplicated stats computation logic.** `compute_outcome_stats()` and `format_outcome_summary()` both independently compute merged_count, closed_count, open_count, merge_rate, and avg_time_to_merge_hours from the same data. That's ~20 lines of identical logic. `format_outcome_summary` has a comment saying "Compute stats inline from the fetched outcomes (avoids a second connection)" — fine, but the right fix is to have a shared internal helper that takes a list of outcomes and returns the stats dict, then both functions call it. Not blocking, but it's the kind of copy-paste that rots over time.

**2. `review_count` computation repeated three times in `poll_outcomes`.** Lines 298, 308, and 346 all do `len(data.get("reviews") or []) + len(data.get("comments") or [])`. Extract a one-liner. It's not about DRY religion — it's about the fact that if the schema changes (e.g., you want to exclude bot comments), you'll have to find and fix three spots instead of one.

**3. `compute_delivery_outcomes` in stats.py guards against `ImportError` on outcomes module.** This is overly defensive — outcomes.py is in the same package, it's always importable. If it somehow isn't, you have a much bigger problem than a missing stats panel. The `try/except ImportError` obscures real errors. The `try/except Exception` around the actual call is fine and sufficient.

None of these are gating. The code is correct, the tests are solid, the feature is complete.

VERDICT: approve

FINDINGS:
- [src/colonyos/outcomes.py]: Stats computation logic (merged_count, merge_rate, avg_time_to_merge) duplicated between compute_outcome_stats() and format_outcome_summary() — should share an internal helper
- [src/colonyos/outcomes.py]: review_count = len(reviews) + len(comments) repeated 3 times in poll_outcomes() — extract a one-liner
- [src/colonyos/stats.py]: Unnecessary ImportError guard around same-package import of outcomes module in compute_delivery_outcomes()

SYNTHESIS:
This is clean, straightforward code that does exactly what the PRD asks for — no more, no less. It follows every existing project convention: SQLite storage, gh CLI subprocess, try/except resilience, Rich CLI output. The data structures are simple and correct. All 8 functional requirements are implemented with 37 new tests and zero regressions across the full 2380-test suite. The three findings are minor code-quality nits (duplicated computation, unnecessary ImportError guard) that don't affect correctness or safety. Ship it.
