 | Resources and authorization | The consumer verifies lost upload ACK, shared pending-image upload, original bytes, metadata, cross-project adoption and reopen. `TestOnboardingAndSharing` additionally revokes source access after warm reads, verifies no target model/version/binding changes, preserves the rejected receipt after permission restoration, and checks independent target access. |
 | AI execution identity and controls | `TestCanonicalAIAdmissionAndLifecycle` covers admission/query/retry, zero-effect rejection, old incarnation callbacks, cancellation, managed image output, owner relocation, archived admission routes and execution after permission revocation. |
 | Actual frontend RunPort | `tests/headless/foundry-ai.integration.mjs` exercises `createFoundryRuns`, the HTTP transport and ProjectEngine: successful admission response loss/reopen/query, queued cancellation response loss, generation-time content conflict, explicit apply response loss plus undo/reopen/redo, generated image metadata/original bytes/preview, and copy without a new run or upload. |
+| Host identity migration coordination | `canvas-migration.ts` now drives the real consumer's initial migration: the server commits, the response is lost, a new coordinator reads the stored body/key and queries the original receipt without a second POST. A later intentional raw POST still checks backend idempotent retry. The coordinator's drain and lock ports are fixtures here; this does not prove the old editor's browser handoff gate is connected. |
