// Phase 08 — F bucket: WS end-to-end equivalence.
//
// The repo does not yet ship an in-process WS server bootstrap helper, so
// these tests exercise the SAME code paths the WS handlers invoke:
//   - Validate() (ConfigConfig.Validate runs the edition gate + handler rules)
//   - PGHookStore.Create + ResolveForEvent (live PG)
//   - DispatcherTestRunner.RunTest (the hooks.test method's underlying runner)
//   - Connect-response equivalence: edition.Current().Name + IsMasterScope
//
// When/if a real WS bootstrap arrives, F1-F4 should be re-implemented over
// it. Until then this is the closest thing to a wire-level guarantee
// without forking the gateway init flow.

// test-F1: master-scope ctx + Standard edition → IsMasterScope=true,
// edition.Current().Name="standard". Equivalent to the values returned in
// the WS connect response shape (`is_master_scope`, `edition`).
