The flow was only documented in code comments scattered across the
catalog, executor, and runner. This guide collects the three-file
contract (catalog / executor / init.ts), the auto-vs-propose policy
matrix, and the drift-guard semantics into one place so future
sessions adding a new module's tools have a single entry point.
