docs(docs): fix the third reader-review round on the Prisma ORM 8 pages

[wmadden-electric]

Follow-up to #8317. That PR ran two reader-review rounds, then changed 15 pages after the second one. This PR runs the third round on those 15 pages, using the docs-reader-review skill.

What changed

Six fresh readers went over the 15 pages, and a seventh then read the rewritten paragraphs. Every sentence #8317 wrote that a reader could not follow is reworded:

• CLI configuration: what each section holds; the pre-rc.12 defineConfig note; how the config search reads parent directories; why extensions are not inherited; a migrations example in the monorepo warning; the // use prisma-8 rule for a single contract file.
• migration plan: the automatic baseline, and what to do when the history splits.
• Middleware: what meta holds; the codecId rule; the AsyncLocalStorage paragraph; the type imports; where currentName.run(...) goes.
• Migrations: what the migration hash covers; the migration new --from paragraph; the intermediate config's extensions; data-only migrations.
• Upgrade pages: the phase 4 contract file; the db sign paragraph on the prisma7Schema path.

Readers also found places where older text contradicted other pages or the code. This PR fixes those:

• Every page that names the CI and production command now gives db migrate --to <ref>.
• The development loop in core concepts applies with --advance-ref db, as the migration pages require.
• migration status and migration log read a database, and core concepts now says so.
• MIGRATION.HASH_MISMATCH means that ops.json or migration.json changed after compiling. The page used to say it meant migration.ts was edited.
• The status column of the "Not available" table now lists the statuses the table uses.

Every fact these rewrites touch was checked against the ORM source.

Checks

• check-plain.sh, check-staccato.py, check-ai-signs.sh: no new hits. One staccato hit is gone.
• pnpm lint:links: 0 errors.
• cspell on the 13 changed files: 0 issues.

Not in this PR

The readers also flagged older text that #8317 did not write. It is left for a separate pass:

• rollbacks-and-recovery still gives plain db migrate for CI.
• The middleware pages disagree with each other in three places: whether after-hooks run when a before-hook throws, what a throw from onRow returns, and what budgets rejects.
• schema-changes has two problems: its section 1.3 contradicts its own "Common gotchas" section on where migration plan starts, and a status output in it shows a literal {bin}.
• how-migrations-work says migrate dev did the job that Prisma ORM 7's db push did.
• the-migration-graph says migration plan always ends at contract.json, but its own rollback row uses --to.

Review details

Systems and components

• observed — apps/docs (service) was modified; 13 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in apps/docs/content/docs/cli/configuration.mdx: The introduction now describes settings as belonging to the orm and skills sections, with the relevant commands reading each section.
• observed — Modified behavior in apps/docs/content/docs/cli/configuration.mdx: The release-candidate guidance now says @prisma/cli-engine no longer exports defineConfig and directs users to definePrismaConfig from prisma/config; the previous guidance allowed importing the renamed function from either package.
• observed — Modified behavior in apps/docs/content/docs/cli/configuration.mdx: The discovery and inheritance explanation now says the CLI reads config files in parent directories up to the repository root, combines each section’s top-level keys by taking each key’s whole value from the nearest config that sets it, and does not inherit extensions when a project config has its own orm section.
• observed — Modified behavior in apps/docs/content/docs/cli/configuration.mdx: The multi-project warning now gives migrations: { dir: "./migrations" } as an example of setting migrations in each project’s config. It retains the warning that inherited database or migration settings can direct commands to another project’s resources.

What it does. A third reader-review round on the 15 Prisma ORM 8 pages that #8317 changed after its second round: 13 pages, 67 additions, 51 deletions, prose only. Sentences readers could not follow are reworded, and five pieces of older text that contradicted other pages are corrected (CI/production command is db migrate --to <ref> everywhere it is named; the core-concepts dev loop applies with --advance-ref db; migration status and migration log read a database; MIGRATION.HASH_MISMATCH means ops.json or migration.json changed after compiling; the "Not available" table intro names the statuses the table uses).

What I checked.

• Full diff, then the code blocks and reference pages each rewritten sentence refers to. The new claims hold against the rest of the docs: db.ts imports BinaryExpr without type and scope-user-selects.ts with it; intermediate.config.ts does use ormConfig({ ... }); migration ref set takes a hash (cli/migration-ref); migration new --from takes only a to hash and no @ name (cli/migration-new); contract-emit#what-it-creates exists and says where the PSL_* codes appear; the codecId table sits under #rewrite-queries-with-beforecompile.
• Gates, run locally at this head: pnpm lint:links 0 errors; pnpm lint:versions clean; cspell on the 13 files 0 issues; check-ai-signs.sh (the Docs Prose CI gate) clean; check-plain.sh hit counts identical to main (the remaining hits are pre-existing text); check-staccato.py one hit fewer than main.
• Branch is not behind main, mergeable, one commit, no files outside apps/docs/content/docs/.

Risk: low. Docs-only, every gate green, and every fact the rewrites touch agrees with the CLI reference pages in this repo. The one thing I could not do is check facts against the ORM source itself, which is not in this repository; the PR says that was done, and nothing I read contradicts it.

Proposed follow-up. The "Not in this PR" list (rollbacks-and-recovery still giving plain db migrate for CI, the three middleware-page disagreements, the two schema-changes problems, the migrate dev/db push mix-up, the-migration-graph's contract.json claim) is proposed as one builder task, awaiting approval, so it does not get lost.

each migration.

What the PR does. Docs only, 13 MDX pages under apps/docs/content/docs, +67/−51. It rewords the sentences a third reader-review round could not follow on the Prisma ORM 8 CLI configuration, migration plan, middleware, migrations, and upgrade pages, and fixes five places where older text contradicted other pages: CI/production commands now consistently say db migrate --to <ref>, the core-concepts dev loop applies with --advance-ref db, core-concepts now says migration status and migration log read a database, MIGRATION.HASH_MISMATCH is described as ops.json/migration.json changing after compile, and the "Not available" table's status column matches the statuses it uses. The last commit takes both CodeRabbit findings: migrate deploy added to the re-sign advice, and the fixture warning now names .deleteAll() instead of .delete().

What I checked.

• check-plain.sh, check-staccato.py, check-ai-signs.sh on the 13 files, compared with the same files on main: no new hits, one staccato hit gone. AI-signs clean on both.
• pnpm lint:links in apps/docs: 0 errors. cspell on the 13 files: 0 issues. The new anchors (/cli/contract-emit#what-it-creates, #rewrite-queries-with-beforecompile) resolve.
• Facts against the published packages, not just the description: in @prisma/orm-family-sql@8.0.0-rc.12, delete() wraps its row lookup and write in withMutationScope (a transaction), while deleteAll() dispatches DELETE … RETURNING straight on the runtime, so the .deleteAll() wording and the ctx.scope explanation are both right. In @prisma/orm-toolchain@8.0.0-rc.12 only migration log and migration status take --db and both only read. prisma@8.0.0-rc.17 exports definePrismaConfig from prisma/config, and @prisma/cli-engine@0.6.1 no longer exports defineConfig. @db, @contract, and @empty exist in the contract-reference grammar. migration new --from and migration ref set match their CLI reference pages.
• main is 4 commits ahead with no overlapping files; the PR reports mergeable.

Risk: low. Prose-only changes to documentation, gates green, and every rewritten claim I could test matches the current release packages.

Follow-up proposed. The five older-text contradictions the PR body lists under "Not in this PR" (rollbacks CI command, the middleware pages' three disagreements, schema-changes 1.3 vs. gotchas, how-migrations-work on migrate dev, the-migration-graph on where migration plan ends) are proposed as one builder task, pending a human's approval. The literal {bin} is excluded, since #8326 covers it as a CLI bug.
