-1. **Branch.** Run `git fetch origin` on its own, then `git switch --no-track -c <type>/<short-name> origin/main` (e.g. `fix/duplicate-ids`, `docs/readme`). `--no-track` stops the branch from tracking `main`.

+5. **Triage.** The review lists unverified candidates, and it will always find some. Check each one against the code. A finding **blocks** only if it is a correctness bug in this PR's change that you have confirmed, ideally with a test that fails. Everything else is a **note**: cleanups, judgement calls, hardening ideas and unconfirmed findings.
-   - First line: **Needs fixes** if any correctness finding still holds after you check it against the code; otherwise **Approved**. Cleanup and judgement-call findings are listed but don't block.
+6. **Comment** on the PR:
+   - First line: **Needs fixes** if anything blocks, otherwise **Approved**.
    - Second line: `_Automated self-review by Claude; not an independent review._`
-   - Then the findings, including any you checked and rejected, and why.
+   - Then the blocking findings, then the notes, then the findings you rejected, each with the reason.
-7. **Fix rounds.** If it needs fixes, first bring in the latest `main`: run `git fetch origin`, then `git merge --no-ff --no-commit origin/main`, then `git commit --no-edit`, each as its own command. Don't rebase, because force pushes are denied. Fix the correctness findings, then repeat steps 2, 3, 5 and 6 (not step 4: the PR already exists). Do at most 2 fix rounds, then post what's left and hand off.
+7. **At most one fix round.** If the PR needs fixes, fix only the blocking findings, each with a test. Push, review once more, and post the verdict from steps 5–6. Then stop, whatever that second review says. Findings about the fixes themselves go to the human as notes; don't fix them.
-8. **Stop.** Never merge, even if approved; tell the human it's ready.
+8. **Hand off.** Never merge, even if the PR is approved. Tell the human it's ready, with the verdict and any notes.
+
+Don't widen scope beyond the PR's purpose to satisfy a review. If a fix would add significant new code (a new mechanism, not a correction), list it as a note for the human instead.
+
+Bring in the latest `main` only when the PR conflicts or the human asks:
+1. Run `git fetch origin`.
+2. Run `git merge --no-ff --no-commit origin/main`.
+3. If it says "Already up to date", stop here. Otherwise resolve any conflicts and run `npm test`.
+4. Run `git commit --no-edit`.
+
+Run each as its own command, and never rebase or force-push.
 
 ### Gitea API
 No `gh`/`tea`: use `curl` with `$GITEA_TOKEN`.
 
-One-time human setup in the git-ignored `.claude/settings.local.json`: set `env.GITEA_TOKEN`, and add `code.westerkam.org` to `sandbox.network.allowedDomains`. Settings load at session start, so restart the session after adding them (`claude --continue`). If the token is unset, stop and ask the human; don't work around it.

 Rules for every API call:
 - Make each call one self-contained command, because shell state doesn't carry over between commands.
-- Write titles and bodies to files in `$TMPDIR` (never in the repo) and pass them with `--rawfile`. Never put them inline in double quotes, where backticks and `$(…)` would run.
+- Put titles and bodies in files in `$TMPDIR` (never in the repo) and pass them with `--rawfile`, never inline in double quotes, where backticks and `$(…)` would run.
-- `pipefail`, `curl -f` and `jq -e` make every failure exit non-zero.
+- The token goes in a private header file, so it doesn't show up in the process list.

-Run `git fetch`, `git commit` and `git push` as standalone commands, with no `cd … &&` before them and nothing chained after. Only then do they run outside the sandbox, which they need to reach the remote and to sign commits.
+Commands listed under `sandbox.excludedCommands` in `.claude/settings.json` (`git fetch`, `git commit`, `git push` and others) run outside the sandbox only when they are run standalone: no `cd … &&` before them and nothing chained after. They need that to reach the remote and to sign commits.
