10 phases, 29 tasks, all worker-ready (WHERE / WHAT / HOW / SAFETY / COMMIT / GIT NOTE per task): Phase 1: Data extraction audit + draft helper script (FR5; TDD) Phase 2: Generate conductor/chronology.md.draft Phase 3: Prune [x]/[shipped] entries from conductor/tracks.md (FR2) Phase 4: Add 3-step archiving convention to conductor/workflow.md (FR3) Phase 5: Write docs/reports/CHRONOLOGY_MIGRATION_20260619.md (FR4) Phase 6: User review of draft (GATE) Phase 7: Promote draft to canonical chronology.md Phase 8: Per-row cross-check (FR6 HARD GATE; 9 batches of ~20 rows) Phase 9: Completeness check (FR6 HARD GATE; folder set vs row set) Phase 10: User sign-off + end-of-track report (FR6 HARD GATE) The cross-check (Phase 8) is the dominant cost. Per the user directive 2026-06-19, EVERY SINGLE ENTRY must be cross-checked. The plan batches the work into 9 commits for review ergonomics; no batch is 'sample-based' or 'looks right' -- each row's 5 fields (date, ID, status, summary, range) are verified independently per FR6. All 12 VCs from the spec are addressed in the plan's 'Verification Criteria Recap' section.
