# Review by Linus Torvalds (Round 2)

Good — `load_run_logs` returns `list[dict]`, so `_sanitize_run_log` receiving a dict is correct.

Now let me write the review output. I have a comprehensive picture of this implementation.

## Review: ColonyOS Web Dashboard

I've reviewed the full diff (2 commits, 33 files, ~4900 lines added) against the PRD. All 941 existing tests pass, the 27 new tests pass. Let me give you the unvarnished assessment.

### What's done right

The architecture is correct. The separation is clean: thin API wrapping existing data-layer functions, no write endpoints, `127.0.0.1` binding, SPA catch-all with path traversal defense. The code does the obvious, straightforward thing at every level — no over-engineered abstractions, no dependency hell. The `create_app()` factory pattern is the right call for testability. The frontend is pleasantly minimal — ~884 lines of TypeScript, well under the 1500-line cap.

The tests are solid: read-only enforcement (POST/PUT/DELETE returning 405), path traversal rejection, sanitization of user content, empty-state handling. That's the kind of defensive testing I want to see.

### Issues Found

**1. Dead code: `_SENSITIVE_CONFIG_FIELDS` (server.py:36)**
This constant `{"slack"}` is defined but **never referenced anywhere**. The `_config_to_dict()` function works by allowlisting fields (manually picking which ones to include), so `slack` is excluded implicitly. But the dead constant is misleading — it suggests there's an active filtering mechanism when there isn't. Either use it or delete it. Dead code is a lie waiting to confuse the next developer.

**2. server.py at 235 lines vs PRD target of 150-200**
The PRD explicitly says "~150-200 lines." You're at 235. It's not egregious — the serialization helpers (`_config_to_dict`, `_stats_result_to_dict`, `_show_result_to_dict`) account for the overshoot. But those helpers exist because the Python dataclasses apparently don't have clean enough `to_dict()` methods. The right fix is to make the dataclasses serialize themselves properly (the PRD notes they have `to_dict()` methods), not to duplicate serialization logic in the server. This is a maintenance hazard — when a field is added to `StatsResult`, someone has to remember to update `_stats_result_to_dict` too.

**3. `web/package-lock.json` committed (2818 lines)**
The PRD says built assets should be committed. It does NOT say `package-lock.json` should be. This is a 2800-line generated file that will create merge conflicts every time someone touches the frontend. Either `.gitignore` it or make a conscious decision about why it's there. The `node_modules/` isn't committed (good), but the lockfile bloat needs justification.

**4. RunDetail polling has a stale closure bug (RunDetail.tsx:30-35)**
```typescript
const timer = setInterval(() => {
  if (data?.header.status === "running") load();
}, POLL_INTERVAL_MS);
```
This captures `data` at the time the effect runs, but `data` is in the dependency array (`[id, data?.header.status]`). Every time `data` changes, the effect re-runs and creates a new interval — which is correct for cleanup. But on the first render, `data` is `null`, so `data?.header.status` is `undefined`, and the interval never calls `load()`. The initial `load()` call works, but if the run IS running, the interval won't fire until after the first successful `load()` updates state, which re-triggers the effect. It works by accident, not by design. The logic should be cleaner — just poll unconditionally and let the server return the current state, or use a ref for the status check.

**5. No `__init__.py` or `py.typed` in `web_dist/`**
Minor, but `web_dist/` is included via `package-data` glob. Verify this actually works in a built wheel — `setuptools` can be finicky about non-Python package data in subdirectories.

**6. CORS allows `localhost:5173` in production**
The CORS middleware allows `http://localhost:5173` (Vite dev server) unconditionally, even when serving production builds. This is a minor security issue — the middleware should only be active in development mode, or the origins should be configurable.

### Completeness Check

All PRD functional requirements are implemented:
- ✅ FR1: `colonyos ui` command with `--port` and `--no-open`
- ✅ FR2: All 6 API endpoints (health, runs, runs/{id}, stats, config, queue)
- ✅ FR3: Dashboard, RunDetail, Config pages with polling
- ✅ FR4: Optional dependency group in pyproject.toml
- ✅ FR5: Build integration with web_dist committed

All tasks marked complete. No TODOs or placeholder code.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/server.py:36]: `_SENSITIVE_CONFIG_FIELDS` is dead code — defined but never used. Delete it or wire it into `_config_to_dict()` as an actual exclusion filter.
- [src/colonyos/server.py]: Three manual serialization helpers (`_config_to_dict`, `_stats_result_to_dict`, `_show_result_to_dict`) duplicate what `to_dict()` on the dataclasses should already do. This is a maintenance hazard — fields added to dataclasses won't appear in API responses until someone remembers to update these helpers too.
- [web/package-lock.json]: 2818-line generated file committed without justification. Will cause merge conflicts. Should be `.gitignore`d or the decision should be explicit.
- [web/src/pages/RunDetail.tsx:30-35]: Polling interval captures stale `data` in closure. Works by accident due to effect re-triggering on status change, but the intent is unclear and fragile. Simplify to unconditional polling or use a ref.
- [src/colonyos/server.py:137-142]: CORS middleware allows `localhost:5173` unconditionally including in production. Should be dev-only or configurable.

SYNTHESIS:
This is competent work that does the right thing architecturally — read-only, local-only, thin wrapper over existing data layer. The scope is contained, the tests are defensive, and the frontend is minimal. My main objection is the manual serialization in `server.py`: you have three separate `_*_to_dict()` functions that hand-pick fields from dataclasses that already have `to_dict()` methods. That's the kind of duplication that will rot silently. The dead `_SENSITIVE_CONFIG_FIELDS` constant tells me someone started building a proper filtering mechanism and then did the allowlist approach instead without cleaning up. Fix the serialization to use the existing `to_dict()` methods (or `dataclasses.asdict()` with field filtering), delete the dead code, and address the CORS dev-only issue. The `package-lock.json` commit and the RunDetail polling bug are secondary but real. None of these are showstoppers — this is a short iteration away from approval.
