A response-contract-exempt comment counted any handler as covered, whatever it returned, so one comment line let a JSON handler past the ratchet. The marker now counts only on a handler taking @Res() or @Next(). The five vacay holiday proxies return the provider's JSON, so they lose their markers and are counted again until they declare a schema.
The decorator records the @trek/shared response schema a route answers
with. Under NODE_ENV=test it adds an interceptor that parses every response
and fails the request with a logged 500 naming the handler and the issues,
so the e2e and integration suites catch a response that drifted from its
contract; in production nothing is added to the request path and the body
is never rewritten. lint:response-contracts holds the handlers still without
one to a per-file baseline that only shrinks, and runs in server-quality.
