docs(docs): contract references after prisma/orm#30475

[wmadden-electric]

The table "Contract references each command accepts" in apps/docs/content/docs/orm/migrations/the-migration-graph.mdx, before:

Command and option	Accepts
migration status --from, --to	a hash, a hash prefix, a ref name, a migration directory name, <dir>^, or @empty
db migrate --to	a hash, a hash prefix, a ref name, a migration directory name, or <dir>^
db migrate --show --to	a hash, a hash prefix, a ref name, a migration directory name, <dir>^, @contract, or @empty
db migrate --show --from	a hash, a hash prefix, a ref name, a migration directory name, <dir>^, @contract, @db, or @empty

After:

Command and option	Accepts
migration status --from, --to	a hash, a hash prefix, a ref name, a migration directory name, <dir>^, @contract, @db, or @empty
db migrate --to, and --from with --show	a hash, a hash prefix, a ref name, a migration directory name, <dir>^, @contract, @db, or @empty

The db migrate rows now list the same forms, so they are one row. The other rows do not change.

Released. prisma/orm#30475 merged as 37f4a0e2ee and shipped in prisma/orm v8.0.0-rc.15. prisma 8.0.0-rc.21 pins @prisma/orm-toolchain 8.0.0-rc.16, and every command in "Re-check on the release" below gave the expected result against prisma 8.0.0-rc.21 and PostgreSQL 15 on 2026-10-07.

What changes

prisma/orm#30475 changes which contract references these commands accept:

• migration status --from and --to accept @contract and @db. @db needs a database connection, even with --from.
• db migrate --to accepts @contract, @db and @empty, with and without --show. @contract behaves like leaving --to out. On a database with no marker, @db names the empty database, so db migrate --to @db reports "Already up to date". --to @empty reports "Already up to date" on an empty database and fails with MIGRATION.PATH_UNREACHABLE on any other.
• db update --to and db sign refuse @contract, @db and @empty with MIGRATION.REF_WRONG_GRAMMAR. Before, db update --to @empty crashed with CLI.UNEXPECTED.

The pages change to match:

• orm/migrations/the-migration-graph.mdx: the table rows above.
• cli/migration-status.mdx: the --to row lists @contract and @db. The --from row and the paragraph under "Reading the result" say that @db needs a database. The "Contract references" subsection defines @contract and @db.
• cli/db-migrate.mdx: the --to row lists @contract, @db and @empty. The "Contract references" subsection says @db names the empty database when the database has no marker.
• cli/db-update.mdx and cli/db-sign.mdx: the contract argument refuses the three @ names, and leaving it out uses the contract in contract.json.

How this was checked

Every claim was run against prisma/orm#30475's final head (858bf5dad8, the tree that merged) with the workspace CLI and PostgreSQL 15. The project had two migrations: a baseline, then one that adds a column, and a prod ref at the baseline. The log of all 29 runs is in that pull request's review folder.

Command	@contract	@db	@empty	./path
migration status --to	ok, 1 pending	ok, up to date	ok	MIGRATION.REF_NOT_FOUND
migration status --from	ok, offline	ok; CONFIG.DB_CONNECTION_REQUIRED with no database	ok	MIGRATION.REF_NOT_FOUND
db migrate --to	ok, applies the pending migration	ok, already up to date (also with no marker)	ok on an empty database; MIGRATION.PATH_UNREACHABLE otherwise	MIGRATION.REF_NOT_FOUND
db migrate --show --to	ok	ok, nothing to run	ok	MIGRATION.REF_NOT_FOUND
db update --to, db sign	MIGRATION.REF_WRONG_GRAMMAR	MIGRATION.REF_WRONG_GRAMMAR	MIGRATION.REF_WRONG_GRAMMAR	MIGRATION.REF_NOT_FOUND

Checks run on the changed pages: check-plain.sh, check-staccato.py and check-ai-signs.sh pass. fumadocs-mdx, pnpm lint:links and cspell run in CI.

Re-check on the release

When a prisma release pins an @prisma/orm-toolchain that contains 37f4a0e2ee, run these in a scratch project and PostgreSQL before marking this ready. Set up two migrations (baseline to H1, then H1 to H2), emit the contract at H2, point prisma.config.ts at a database at H1, and make a second config with no db.connection.

npx prisma migration status --to @contract           # ⚠ 1 pending
npx prisma migration status --from @contract         # ✔ Up to date, no database line
npx prisma migration status --to @db                 # ✔ Up to date
npx prisma migration status --from @db               # ⚠ 1 pending, baseline ✓ applied
npx prisma migration status --from @db --config prisma.nodb.config.ts   # CONFIG.DB_CONNECTION_REQUIRED
npx prisma db migrate --to @contract --db <db at H1>    # Applied 1 migration
npx prisma db migrate --to @db --db <db at H1>          # Already up to date
npx prisma db migrate --to @db --db <empty db>          # Already up to date
npx prisma db migrate --to @empty --db <empty db>       # Already up to date
npx prisma db migrate --to @empty --db <db at H1>       # MIGRATION.PATH_UNREACHABLE
npx prisma db migrate --show --to @db                # Already up to date, nothing to run
npx prisma db migrate --show --to @contract          # 1 migration will run
npx prisma db migrate --show --from @empty --to @db  # 1 migration will run
npx prisma db update --dry-run --to @contract        # MIGRATION.REF_WRONG_GRAMMAR
npx prisma db update --dry-run --to @db              # MIGRATION.REF_WRONG_GRAMMAR
npx prisma db update --dry-run --to @empty           # MIGRATION.REF_WRONG_GRAMMAR
npx prisma db sign @contract --db <db at H1>         # MIGRATION.REF_WRONG_GRAMMAR
# each of these must still fail with MIGRATION.REF_NOT_FOUND:
npx prisma migration status --to ./migrations/app/<baseline dir>
npx prisma db migrate --to ./migrations/app/<baseline dir> --db <db at H1>
npx prisma db update --dry-run --to ./src/prisma/contract.json
npx prisma db sign --contract ./src/prisma/contract.json --db <db at H1>

Walkthrough

The documentation updates clarify accepted and rejected contract references for migration commands. They also describe when migration status requires database access and update the migration graph reference table.

Changes

Migration reference documentation

Layer / File(s)	Summary
CLI reference rules apps/docs/content/docs/cli/db-migrate.mdx, apps/docs/content/docs/cli/db-sign.mdx, apps/docs/content/docs/cli/db-update.mdx	The command documentation lists accepted or rejected references. It clarifies the meaning of @db and the default contract for db update.
Status references and reference table apps/docs/content/docs/cli/migration-status.mdx, apps/docs/content/docs/orm/migrations/the-migration-graph.mdx	The status documentation defines @contract and @db and states when a database is required. The migration graph table lists accepted references for the documented commands.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to 577e3

The latest published CLI may reject @contract or report an empty state for @db, despite the new instructions. Defer publishing these docs until a supporting CLI release is available.

• observed — apps/docs (service) was modified; 5 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in apps/docs/content/docs/cli/db-migrate.mdx: The --to description now lists @contract and @db among its accepted references without limiting them to --show; it no longer says that @empty is accepted with --show.
• observed — Modified behavior in apps/docs/content/docs/cli/db-migrate.mdx: The @db description now specifies that it refers to the database’s marked contract state, or to the empty database when there is no marker.
• observed — Modified behavior in apps/docs/content/docs/cli/db-sign.mdx: The [contract] description adds that @contract, @db, and @empty are refused with error code MIGRATION.REF_WRONG_GRAMMAR.
• observed — Modified behavior in apps/docs/content/docs/cli/db-update.mdx: The --to documentation now specifies the default contract when the option is omitted and names the rejected references and resulting error code.
