Integration checkpoint for epic-proxy-activity-registration-orchestration
epic-proxy-activity-registration-orchestration-integration-task — Integration Task
Integration Purpose
Verify integration with dependent epics: epic-proxy-activity-registration-core-services
This integration checkpoint ensures proper coordination and compatibility between different epics. It verifies that all interfaces, data flows, and dependencies are correctly implemented before proceeding.
Integrates With Epics
Execution Context
Tier 4 - 323 tasks
Can start after Tier 3 completes
Handles integration between different epics or system components. Requires coordination across multiple development streams.

If the Supabase batch RPC partial-inserts some records before encountering an error and does not roll back cleanly, the bulk service may report failure while orphaned records exist in the database, corrupting reporting data.
Mitigation & Contingency
Mitigation: Wrap the bulk insert in an explicit Supabase transaction via the RPC function. Write an integration test that simulates a mid-batch constraint violation and asserts zero records were written.
Contingency: If a partial-write incident occurs, the registered_by audit field allows identification and deletion of the orphaned records. Implement a coordinator-facing bulk submission status screen to surface any such anomalies.
When a bulk submission of 15 participants has 4 duplicates, the aggregated conflict summary may be too complex for coordinators to process quickly, leading to blanket override decisions that defeat the purpose of duplicate detection.
Mitigation & Contingency
Mitigation: Design the conflict result type to support per-participant override flags, so the UI can present a clear list of conflicting participants with individual cancel/override toggles rather than a single global decision.
Contingency: If coordinator usability testing reveals the conflict review screen is too complex, simplify to a 'skip all conflicts and submit the rest' mode as an immediate fallback while a more granular UI is designed.
If the coordinator role check inside proxy-registration-service is inconsistent with the route-level guard, a regression in the guard could allow peer mentors to call the service directly via deep links, submitting records with incorrect attribution.
Mitigation & Contingency
Mitigation: Enforce role authorization at both the route guard level (coordinator-role-guard) and inside each service method independently. Write a security test that calls the service directly with a peer mentor session token and asserts rejection.
Contingency: If a bypass is discovered, immediately enable the server-side RLS policy as the final enforcement layer and audit any records written during the exposure window using the registered_by field.
