 - Dependencies: `uv.lock` is committed; regenerate with `./dev.sh uv lock`
   after changing `pyproject.toml`.
 - Commits: atomic, no `--amend`; run ruff + pytest + shellcheck before
   committing. Add a memory of anything a future session could not derive
   from the repository.
+- Releases: bump `version` in `pyproject.toml` (must match the tag), commit,
+  then `git tag -a vX.Y.Z && git push origin vX.Y.Z`, build with
+  `./dev.sh uv build` (writes `dist/`, gitignored), write `SHA256SUMS`, and
+  `fj release create --tag vX.Y.Z --attach dist/<wheel> --attach dist/<sdist>
+  --attach dist/SHA256SUMS --body "..." "vX.Y.Z"` from inside the repo –
+  `fj release` does **not** accept `--repo`. Then update the "Latest:" line
+  in the README's Releases section and delete `dist/`.
