Migration 015 adds merge_commit_sha/squash_commit_sha to merge_requests (Gate 4/5 prerequisites), closes_issues_synced_for_updated_at watermark for incremental sync, and the missing idx_label_events_label index. The MR transformer and ingestion pipeline now populate commit SHAs during sync. The orchestrator uses watermark-based filtering for closes_issues jobs instead of re-enqueuing all MRs every sync. The Phase B PRD is updated to match the actual codebase: corrected migration numbering (011-015), documented nullable label/milestone fields (migration 012), watermark patterns (013), observability infrastructure (014), simplified source_method values, and updated entity_references schema to match implementation.
