Complete 5 beads for the Phase B temporal intelligence feature: - bd-1oo: Register migration 015 (commit SHAs, closes watermark) and create migration 016 (mr_file_changes table with 4 indexes for Gate 4 file-history) - bd-20e: Define TimelineEvent model with 9 event type variants, EntityRef, ExpandedEntityRef, UnresolvedRef, and TimelineResult types. Ord impl for chronological sorting with stable tiebreak. - bd-32q: Implement timeline seed phase - FTS5 keyword search to entity IDs with discussion-to-parent resolution, entity dedup, and evidence note extraction with snippet truncation. - bd-ypa: Implement timeline expand phase - BFS cross-reference expansion over entity_references with bidirectional traversal, depth limiting, mention filtering, provenance tracking, and unresolved reference collection. - bd-3as: Implement timeline event collection - gathers Created, StateChanged, LabelAdded/Removed, MilestoneSet/Removed, Merged, and NoteEvidence events. Merged dedup (state=merged -> Merged variant only). NULL label/milestone fallbacks. Chronological interleaving with since filter and limit. 38 new tests, all 445 tests pass. All quality gates clean.
