The first run shipped chronology.md with a status classifier that read stale
metadata.json.status, marking 167/216 rows with wrong status. This v2 spec
replaces FR1 (5-value status enum + per-row evidence + confidence), FR5
(git-history classifier with the 5-step algorithm from the handover), FR6
(3-stage cross-check), and adds FR7 (classifier quality gate at 30% low
confidence threshold with abort-to-manual-review fallback).
Substantive changes from v1:
- 7 FRs (was 6); FR7 is new
- 14 VCs (was 12); VC10-VC14 are new
- 10 Risks (was 9)
- 5-value status enum: Active / In Progress / Completed / Abandoned / Special
(was 6-value: Shipped/Superseded/etc.)
- Per-row evidence line format documented with worked example
- 'Needs Review' section as a 5th section in chronology.md
- Quality gate hard-codes the user's 'A only if classifier is good, else B'

Out of scope: 24 v1 commits + conductor/chronology.md.broken-v1 remain as the
foundation; this is a continuation, not a re-do. state.toml still shows
current_phase=10 from v1's false completion; the Tier 2 implementing agent
will reset it in Phase 1.4 of the plan.
