feat(P2): metrics collector — SQLite cold store + Decision Ledger CLI (REQ-189,200,201,207)
P2 (Wave 2, feat) — REQ-189, REQ-200, REQ-201, REQ-207
New components:
- core/metrics/collector.py — reads all grounded signals (REGRESSION_REPORT.json,
per-run manifests, junit XML, coverage.json, decision ledger, lifecycle reports)
→ SQLite cold store (metrics/nova_metrics.db) with fact_run, fact_capability,
fact_policy_check, fact_confidence, fact_test, fact_decision, fact_cost_estimate,
fact_lifecycle, dim_capability, dim_milestone tables
- core/metrics/decision_ledger_cli.py — CLI with query/verify-chain/stats/export/replay
- tests/test_metrics_collector.py — 7 tests (all pass, incl. idempotent re-run REQ-200)
D-120: Nova-native (SQLite, no ClickHouse)
D-125: hybrid (reads files + events → SQLite)
D-126: cold-only (no hot path)
