# Review by Linus Torvalds (Round 3)

Here's my review as Linus Torvalds:

VERDICT: approve

FINDINGS:
- [src/colonyos/server.py]: Clean, 176 lines — within the PRD's 200-line target. Wraps existing data-layer functions without re-inventing anything. No write endpoints. Good.
- [src/colonyos/server.py]: Path traversal defense done correctly — reuses `validate_run_id_input()` and has `is_relative_to()` defense-in-depth on the SPA catch-all. Not clever, just correct.
- [src/colonyos/server.py]: CORS gated behind `COLONYOS_DEV` env var. Sensitive config fields redacted. Localhost-only binding. All sane.
- [src/colonyos/server.py]: Late import of `load_single_run` inside `get_run()` handler — should be a top-level import for clarity. Not a blocker.
- [src/colonyos/cli.py]: Proper import guard for uvicorn, clear install message, `127.0.0.1` binding, `webbrowser.open()` before the blocking `uvicorn.run()` call.
- [tests/test_server.py]: 478 lines covering all endpoints, read-only enforcement (405 on POST/PUT/DELETE), path traversal, sanitization, CORS, config redaction. Thorough.
- [web/src/]: ~1219 lines of TypeScript total, within the 1500-line target. Small focused components, simple fetch→state→render data flow, proper polling cleanup.
- [pyproject.toml]: Optional `[ui]` deps, `web_dist/**` in package-data. Core install path unaffected.
- [web/package.json]: No `package-lock.json` committed — non-deterministic contributor installs. Minor, since built assets are committed.
- [README.md]: Three clean lines documenting the new command.

SYNTHESIS:
This is a well-scoped, well-executed optional feature. The implementation follows the existing codebase patterns correctly — it wraps the data-layer functions that were already cleanly separated from Rich rendering, which is exactly what you want. The server is 176 lines, read-only, localhost-bound, with proper input validation and content sanitization. The frontend is under 1300 lines of straightforward React — no state management library, no abstraction astronautics, just fetch-and-render. All 945 tests pass including 31 new ones with good coverage of security concerns (path traversal, read-only enforcement, config redaction, XSS sanitization). The one nitpick: move the late import inside `get_run()` to the top of the module. But it's not worth blocking on. The scope was contained exactly as promised. Ship it.
