feat(ledger): add Schema V10 DDL migration for decision deepening#335
Conversation
…-329) Add 6 new columns to decisions table: status, authority, affected_paths, tags, review_after, reversibility. Backfill status from existing is_active boolean to maintain COMPAT-01 invariant. Add indexes on status, status+domain, and affected_paths for query performance. Add 3 tests: fresh V10 DB, V9->V10 migration with backfill verification, and backward compatibility for is_active queries.
