What Boundary does
description: Map the public API + interface boundaries of a brownfield codebase. Fourth link in the chain. Persists BOUNDARY contracts.
Invoke the hew-boundary skill. Identifies the project's public surface — HTTP routes, exported types, library entry points, schema-bearing files — and persists each one as a `BOUNDARY:` memory describing the contract that downstream callers depend on.
The executor reads these before refactors. Breaking a `BOUNDARY:` contract triggers `hew-execute
