Integration checkpoint for epic-peer-mentor-pause-management-core-workflows
epic-peer-mentor-pause-management-core-workflows-integration-task — Integration Task
Integration Purpose
Verify integration with dependent epics: epic-peer-mentor-pause-management-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
Handles integration between different epics or system components. Requires coordination across multiple development streams.

Concurrent status transitions (e.g., coordinator and automated scheduler both attempting to update the same mentor's status simultaneously) may produce race conditions or inconsistent state in the database, leading to audit log gaps or incorrect notifications.
Mitigation & Contingency
Mitigation: Implement all status transitions as atomic Postgres RPC functions with optimistic locking (version column or updated_at check). Use database-level constraints rather than application-level guards as the final enforcement point.
Contingency: Add a compensation job that reconciles status and log table consistency on each nightly scheduler run, surfacing any discrepancies to coordinator dashboards.
The coordinator-to-mentor assignment relationship may not always be 1:1 or may be stale (coordinator reassigned after a pause was set), causing notifications to be sent to the wrong coordinator or not sent at all.
Mitigation & Contingency
Mitigation: Query the assignment relationship at notification dispatch time rather than caching it at pause creation time. Add a fallback to notify the chapter administrator if no active coordinator assignment exists.
Contingency: Log all undeliverable notification attempts with the originating mentor ID so administrators can manually follow up, and surface undelivered notification counts on the coordinator dashboard.
The CoordinatorPauseRosterScreen may load slowly for coordinators managing large rosters with many concurrent certification expiry queries, degrading usability on low-bandwidth mobile connections.
Mitigation & Contingency
Mitigation: Use a single Supabase RPC that joins mentor status, certification expiry, and assignment data in one query rather than N+1 individual calls. Implement pagination with a configurable page size and skeleton loading states.
Contingency: Add an offline cache of the last-fetched roster state using Riverpod with SharedPreferences, ensuring coordinators can at minimum view stale data when connectivity is poor.
