19 tasks across 8 waves covering events with lifecycles, time skips
(elision + jump), active threads, significance/retrieval refinements,
and meanwhile scenes (host+guest with no 'you'). Mirrors the Phase 2
plan structure: pre-flight, parallel-execution strategy with worktree
isolation, file-disjointness analysis per wave, and per-task TDD spec
with commit messages.
Phase 3 schema: adds 0009_events.sql, 0010_threads.sql,
0011_meanwhile_scenes.sql (final version 11). Builds on Phase 2's
3-entity scene support and event-sourced architecture.
