Prisma migrate diff proposed DROP TABLE "_goldbank_migrations" because the
table exists in the database but was not declared in the schema. Declaring
it with @@ignore removes the proposal without exposing it to Prisma Client,
and the table and all its rows are kept.
Correcting the earlier DEAD-07 note: this is not a leftover from the
pre-Prisma port. It is the tracking table of the application's own
migration runner (src/prisma/migrate.ts:5), which exists because the Docker
deploy image is copy-only and ships no Prisma CLI, so migrate deploy cannot
run in the container (migrate.ts:7-13). The project therefore keeps two
ledgers deliberately: _prisma_migrations for the CLI in development, and
_goldbank_migrations for the runtime runner in the container. That runner
already filtered out any DROP of its own table (migrate.ts:190-196); the
schema declaration removes the cause rather than relying on that guard.
The practical consequence, recorded in DECISIONS.md D15: a new migration
must be safe under both paths, so its SQL stays idempotent.
The ledger grew 12 -> 14 rows while testing, with nothing deleted: starting
the API ran prepareDatabase(), which appended the two migrations applied
earlier today. Its $$-aware statement splitter handled the PL/pgSQL trigger
body correctly — trigger and function are both present and the 9 trigger
assertions pass against the live database.
Also records the UTF-8 testing rule: Persian test input must come from a
file, never a shell argument, because the Windows shell replaces Persian
characters with '?' and a test can then pass while storing '????'.
Verified: migrate diff -> "This is an empty migration" (zero drift);
migrate status -> up to date; tsc clean; 32 jest; 9 trigger assertions.
