Task action read-version mapping
Verification Boundary
This suite checks deterministic module behavior with direct assertions.
What This Suite Proves
The mapper retains the supplied action version and refuses a body that omits it.
The registered scenario bindings identify the assertion contributions this executable supplies. A compound scenario can require several suites.
What It Does Not Prove
It does not establish deployed Lambda transport, live Platform policy or end-user browser behavior.
Real Dependencies and Test Doubles
The actual helper, schema, mapper or declaration under test runs with fixed inputs. These cases use no database or deployed service.
Must Not Be Doubled
The decision, mapper, declaration or error response being asserted remains the real implementation.
