   specification anchors, not demos — the E2E suite hangs off them.
-- **Agents** (`agents/`): specialised sub-prompts (implementer,
-  architect, tester, debugger) that form the project's own LLM tooling.
-  They are a versioned part of the repo. See `agents/README.md`.

   new compiler path needs a test, otherwise the feature does not count as done.
