 - Alembic revisions in migrations/versions/ are the ordered schema history for persistent environments.
 - app/repositories/postgres.py includes ensure_schema() for bootstrap safety, but long-term schema evolution should run through Alembic.
-- Current Alembic head is `20260814_0029`; its strategy columns, default seed, and constraints are guarded for ensure_schema-first and repeatable execution.
+- Current Alembic head is `20260820_0030`; the preceding `0029` strategy columns, default seed, and constraints and the `0030` unified-ledger keyset index are guarded for ensure_schema-first and repeatable execution.
 - Comments, tags, auth tokens, and ledger rows are normalized into dedicated tables keyed to users or portfolios.
