 - [x] `BUG`: Remove host-side fallback path for review execution, or gate it behind explicit `ALLOW_HOST_FALLBACK=false` by default so isolation cannot be bypassed silently.
 - [x] `BUG`: Enforce `.codex-review.yml` `enabled=false` at runtime (currently loaded but not enforced).
-- [x] `BUG`: Remove `.codex-review.yml` fix policy (`commands.allow_fix`) and rely on global `ENABLE_FIX_COMMANDS`.
+- [x] `BUG`: Remove fix command support from runtime and command parsing.
 - [x] `BUG`: Add stuck-job recovery for `running` jobs (lease timeout + requeue/fail) so one crashed worker does not deadlock the queue.
 - [x] `BUG`: Validate required secrets/settings are non-empty at startup (`GITEA_WEBHOOK_SECRET`, `GITEA_TOKEN`, `ALLOWED_REPOS`) and fail fast if blank.
 - [ ] `TEST`: Add integration test proving the runner executes the exact PR head SHA in isolated mode and does not rely on host checkout.

Other routes than "/" should return a 404 with if a browser accessed it a again, tailwind cdn themed 404 page. Both should be nicely designed and minimalistic.
