Competing shared-work requests

Verification Boundary

This suite checks module reads, writes or presentation against persisted fixtures.

What This Suite Proves

Concurrent database requests check queue and role claim winners, winner-specific conflicts, release races and singular workflow creation.

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 persistence or presentation functions execute against the migrated PostgreSQL database and fixture execution contexts. Role eligibility uses local Platform security fixtures rather than a deployed security-service lifecycle.

Must Not Be Doubled

The database queries, constraints, version checks, workspace policies and transaction boundaries under assertion remain real.
