Integration checkpoint for epic-peer-mentor-detail-screen-data-layer
epic-peer-mentor-detail-screen-data-layer-integration-task — Integration Task
Integration Purpose
Verify integration with dependent epics: epic-peer-mentor-detail-screen-foundation
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 2 - 518 tasks
Can start after Tier 1 completes

Supabase RLS policies for peer mentor data may block coordinator queries if the RLS rules are written for peer-mentor-self access only, requiring policy updates that affect other features sharing the same tables.
Mitigation & Contingency
Mitigation: Review existing RLS policies on peer_mentors, certification_records, and activity_log tables before writing repository queries. Coordinate with the database team to add coordinator-role predicates without weakening existing mentor-self policies.
Contingency: If policy changes are blocked, implement a Supabase Edge Function as a secure query proxy that enforces authorization server-side, avoiding direct RLS policy modification.
The activity log table schema may not have a mentor_id foreign key column or may require a JOIN through an intermediate table, making the aggregation query significantly more complex than anticipated.
Mitigation & Contingency
Mitigation: Inspect the actual Supabase activity_log table schema before starting the MentorActivityLogRepository implementation. Document the exact JOIN path needed and validate it returns correct results for a known mentor.
Contingency: If schema requires complex multi-table aggregation, implement a Supabase database function (RPC) and expose it via the repository's fetchSummary method to keep Dart code clean.
The Blindeforbundet assignment table may not yet exist in the shared Supabase schema or may have a different structure than assumed, blocking the AssignmentHistoryRepository implementation.
Mitigation & Contingency
Mitigation: Verify the assignments table exists and confirm its column structure with the Contact Detail & Edit Screen team which also depends on assignment data (assignment-repository in that feature).
Contingency: If the assignments table is not yet available, implement the AssignmentHistoryRepository with a stub returning empty list and a TODO marker, unblocking the aggregation service while the schema is finalized.
