Migration 1: remove idx_sessions_token_hash from _SCHEMA_STATEMENTS. The legacy schema has sessions.token (not token_hash). The IF NOT EXISTS guard only prevents duplicate index names — it still requires the column to exist. Migration 2 drops and rebuilds sessions with token_hash anyway, so creating the index in migration 1 was redundant. Migration 3: replace ALTER TABLE ADD COLUMN with a table rebuild. SQLite rejects ALTER TABLE ADD COLUMN NOT NULL DEFAULT <expression> when the table already contains rows. The old DB has ~181k geo_cache rows, so the ALTER always failed. Rebuild copies existing rows with last_seen set to cached_at as a reasonable approximation of last-seen time.
