`release-prod.yml` for api and auth, mirroring the edge's. The gate is not
"you may not merge" — it is that merging does not deploy: tests run against a
real Postgres, both binaries are executed, and a failure anywhere means no
release exists, so the machine keeps serving what it has.
The new piece is `nestri-migrate`, because the deploy runs migrations *before*
it swaps a release into place and had nothing to run.
`drizzle-kit migrate` reads the migrations folder at runtime, which is right on
a laptop and wrong on a server: the deploy ships flat, checksummed files into
bin/, and a migrator that needs a directory beside it can be pointed at the
wrong directory. So the folder is baked into the binary — generated on every
build rather than committed, so it cannot drift — and the artefact's checksum
then covers every statement it will run.
It reimplements drizzle's bookkeeping in thirty lines of SQL rather than
calling into `db.dialect.migrate`: same table, same schema, same sha256 over
the whole file, same high-water-mark comparison. That equivalence is the one
thing that must not rot, because the production database was first migrated by
drizzle-kit and a disagreement means a migration applied twice. Two checks
hold it: CI applies the migrations with drizzle-kit and then asserts the
embedded set reports nothing pending, and the hashes were verified by hand
against the live database — all fourteen match to the byte.
Proven before shipping, against the real database: nothing pending on the
deployed schema, 14 unchanged rows, and a scratch database migrated from empty
to the same 22 tables and the same high-water mark, idempotent on a second run.
Refuses with exit 2 when DATABASE_URL is absent rather than defaulting to
localhost, which would be a migrator reporting success having migrated nothing.
setup-bun is pinned to a commit and not to `v2`. A moving major tag is fine
everywhere else in this repository; this workflow is the only thing between a
merge and a process serving users, and there is no first-party bun action to
prefer instead.
