All content from 003_add_device_codes.sql and 004_add_trigram_indexes.sql
was already absorbed into db/schema.sql (the single source of truth).
The migrations had additional problems:
- Broken numbering (started at 003, missing 001/002)
- 004 used CREATE INDEX CONCURRENTLY which fails inside sqlx transactions
- No production flow ever invoked the migrate binary
Removed: db/migrations/, src/bin/migrate.rs, migrations Cargo feature,
[[bin]] migrate target, and doc/database-migrations.md.
