+## Engineering work: the compound loop
+
+The owner, 18 October 2026, as in ww3-gpu: when the owner guides engineering work (a tool, a
+check, a script, the site), agents follow Compound Engineering's loop. The plugin
+(`compound-engineering@compound-engineering-plugin`, EveryInc, MIT) is enabled in
+`.claude/settings.json`, pinned to `compound-engineering-v3.30.3`. The book's text is not
+engineering work: notes, essays and prose follow their own rules above.
+
+| Size | Example | Steps |
+|---|---|---|
+| Small | a fix in one file, a doc, a flag | work, `just check`, a pull request |
+| Medium | a tool, a check, a recipe | `/ce-plan`, `/ce-work`, `/ce-code-review`, `/ce-compound` when the lesson is not obvious from the diff |
+| Large | a new tool family, a change to the build | `/ce-brainstorm` first, then the medium loop |
+
+Where a step's default clashes with a rule of this file, the rule wins:
+
+- Plans go to `docs/compound/plans/`, learnings to `docs/compound/solutions/`
+  (`.compound-engineering/config.yaml`).
+- `/ce-work` works on a branch and opens a pull request; it never merges, tags or releases
+  (invariants 6 and 8).
+- `/ce-code-review` reports and does not rewrite. Its cross-model pass is off, because it would
+  send the diff to another provider; the owner can ask for it in a run.
+- `/ce-compound` never edits this file or `CLAUDE.md` unless the owner agrees in that session.
+- `/lfg` (the whole pipeline unattended) runs only when the owner asks for it.
+
+Drawings of a flow use the `archify` skill; their sources and PDFs live in `docs/archify/`
+(`just archify`).
