feat(engine): a config section schema declares which values are references - #284
Merged

Conversation
…ences The engine kept a config file's objects by guessing from their type: its clone copied plain objects and arrays and kept everything else. A section schema now says which values the config file constructs: reference(schema) validates the value against schema, records it for the current validation, and the clone the config scope gives arktype copies every value except the recorded references. A descriptor, a client or a class instance reaches the command as the file's own object; anything not declared a reference is copied, whatever its type. A reference cannot contain a path or a default, because resolving one would write into the file's own object. reference() refuses such a schema when it is defined, by comparing the schema's input and output expressions. ADR 0005 and the package AGENTS.md describe the rule.

…as references Each control descriptor (family, target, adapter, driver, every extension) and db.connection is declared with the engine's reference(), so the command receives the object the config file built. Every other value is copied before paths are resolved and defaults applied. The test asserts identity again, and the arktype reference doc describes declared references instead of the plain-object rule. Needs @prisma/cli-engine with reference() (prisma/prisma-cli#284); the pins move once it is published.

…ngine resolves its paths (prisma#30372) ## At a glance The `orm` section of `prisma.config.ts` is declared once, with the fields that are paths marked as such: ```ts // packages/1-framework/3-tooling/config-loader/src/orm-section.ts export const ormConfigSchema = configSchema({ family: { kind: "'family'", ...descriptorFields, emission: 'object' }, target: { kind: "'target'", ...targetLikeFields }, adapter: { kind: "'adapter'", ...targetLikeFields }, 'driver?': { kind: "'driver'", ...targetLikeFields }, 'extensions?': [{ kind: "'extension'", ...targetLikeFields }, '[]'], 'db?': { 'connection?': 'unknown' }, 'contract?': { source: { load: 'Function', 'inputs?': 'path[]', 'format?': 'string' }, output: ['path', '=', () => 'src/prisma/contract.json'], }, migrations: [{ dir: ['path', '=', () => './migrations'] }, '=', () => ({})], 'formatter?': { 'indent?': "number.integer >= 1 | 'tab'", 'newline?': "'LF' | 'CRLF'" }, }).narrow(/* familyId and targetId agreement across descriptors */); ``` Given this project and this invocation: ``` exp/ sub/ prisma.config.ts # orm: ormConfig({ contract: './contract.prisma', migrations: { dir: './migrations' } }) contract.prisma ``` | Run from | Command | Before | After | | --------- | ------------------------------------------------------ | -------------------------------------------------------------- | ------------------------------ | | `exp/sub` | `prisma contract emit --config ./prisma.config.ts` | writes `exp/sub/contract.json` | same | | `exp` | `prisma contract emit --config ./sub/prisma.config.ts` | `CONTRACT.SOURCE_LOAD_FAILED`: looks for `exp/contract.prisma` | writes `exp/sub/contract.json` | Config files are unchanged. ## The decision A relative path in `prisma.config.ts` is relative to the file that wrote it. Only the ORM knows which of its fields are paths; only the CLI engine knows which file wrote each value, because its chain merge records that per key. The schema declaration puts the first where the second can use it. The engine derives validation, a `CLI.CONFIG_FIELD_INVALID` diagnostic per bad field naming the file to fix, and the resolution of every `path` field, from the one declaration; the ORM writes no validation, resolution, or path-anchoring code. This is [prisma/prisma-cli ADR 0005](https://github.com/prisma/prisma-cli/blob/main/docs/architecture/adrs/0005-config-sections-declare-their-shape.md), shipped in engine 0.6.0 by prisma/prisma-cli#279; every product that mounts commands declares its section this way. ## Why it broke The ORM's own `prisma` bin resolved config paths in its loader against the config file. The unified `prisma` CLI loads the config through the engine's loader, which handed the `orm` section over as written; the ORM's command wrapper then resolved paths itself, and the only directory it could see was the working directory. The same defect existed a second time in `projectConfigPathFor`, which rebuilt `<cwd>/prisma.config.ts` to find the project's `package.json` and, from a parent directory, read the wrong manifest. ## What changes - **`@internal/config-loader`** declares `ormConfigSchema` and `ormConfigSection` (`defineConfigSection({ name: 'orm', schema })`). It is the lowest package that can depend on the engine; `@internal/cli` and `@internal/cli-telemetry` consume the section from it. Path defaults are thunks, which arktype evaluates when the default is applied, so they resolve against the config file like authored values. - **Descriptors are declared references.** A control descriptor is a runtime object the config file constructs: `create` closes over module state, and its codec tables, contract serializer and migration hooks rely on their prototypes and on `this`. The schema declares each descriptor, and `db.connection`, with the engine's `reference(schema)` (prisma/prisma-cli#284), so the command receives the object the config file built. The schema checks only a descriptor's identifying fields: `kind`, `id`, `familyId`, `version`, `create`, and `targetId` or `emission`. Every value not declared a reference is copied before paths are resolved and defaults applied. Cross-descriptor rules (`familyId` and `targetId` agreement, the removed `extensionPacks` key) are one function, which the schema's `narrow` and the loader both call. - **A codec without params has no `paramsSchema`.** A codec that took no params used to declare `paramsSchema = voidParamsSchema`, a shared schema accepting only `undefined`, and `isParameterized` asked whether a descriptor's schema was that exact object. A copied descriptor carries a copy of that schema, so every codec on it reported itself parameterized, which is how `db init` failed with `Invalid typeParams for codec 'pg/text@1'`. `paramsSchema` is now `StandardSchemaV1<P> | undefined`, a codec without params sets it to `undefined`, and `isParameterized` is `paramsSchema !== undefined`, which no copy can change. Type-param validation still rejects `typeParams` for such a codec with `RUNTIME.TYPE_PARAMS_INVALID`. `voidParamsSchema` is removed; [`upgrade-instructions/pending/codec-without-params-schema/extension/`](https://github.com/prisma/orm/blob/feat/orm-config-schema/upgrade-instructions/pending/codec-without-params-schema/extension/instructions.md) tells extension authors how to follow. - **The ORM's bin** hands the engine each evaluated file with its sections as written (`loadConfigFiles`); the engine validates the merged section with that provenance before a command runs. `loadConfig` runs the same schema for the language server and the vite plugin, wrapping each field diagnostic as `CONFIG.VALIDATION_FAILED` with the subsection it concerns, so `requireConfigSections` keeps working. - **Commands** read absolute paths and `baseDir`. The command wrapper's cwd finalisation, `finalize-config.ts`, `collectConfigIssues` and its hand-written descriptor checks, and `projectConfigPathFor` are deleted. The migration path helpers take only the config. Control API operations that located the project through `configPath` take `projectDir`; `resolveMigrationPaths` takes the config. - **`@prisma/cli-engine` moves to 0.6.1** (0.6.0 plus prisma/prisma-cli#280 and #284: a schema declares the values it keeps as references) in `@internal/cli`, `@internal/config-loader`, `@prisma/orm-toolchain`'s peer, the four extension packages, and the integration test package. The `defineConfig` → `definePrismaConfig` rename the bump requires landed separately in prisma#30129. Examples and fixture apps consume published packages and keep their pins. - **Diagnostics under the unified CLI change code.** A malformed `orm` field is now reported by the engine as `CLI.CONFIG_FIELD_INVALID` (one per field, `meta.section: 'orm'`, `meta.field` the dotted path, `where.path` the config file that declared it) under `CLI.CONFIG_SECTION_INVALID`. `CONFIG.VALIDATION_FAILED` remains what the ORM's own loader raises for the language server and the vite plugin. The error reference records the split; the two integration files that asserted the old code are updated. - **Docs**: `config-validation-and-normalization.mdc` now describes the schema as the single home of structural rules, `loadConfigFiles`/`loadConfig` as evaluation plus diagnostics, and path resolution as the schema's job; the CLI Style Guide says relative paths in the config file resolve against the file that wrote them, with `--output-path` the one path relative to cwd; the loader README follows. The arktype rule now says to read the arktype docs before building validation machinery and never to read arktype's compiled node tree, and `docs/reference/arktype-usage.md` records what a transformation does to its input: any pipe or default makes arktype clone the whole input, and the default clone rebuilds plain objects and class instances. The codec authoring guide, the two codec ADRs and the package READMEs declare codecs without params with `paramsSchema = undefined`. ## Tests - `framework-components/test/materialize-codec.test.ts`: a descriptor copied the way arktype's default clone copies it keeps `isParameterized` for codecs with and without params (this test fails before the change), and a codec without params rejects `typeParams`. - `config-loader/test/orm-section.test.ts`: the schema accepts a valid config, supplies the migrations dir and default contract output, records `baseDir`, resolves inputs, output and migrations dir against the config file, leaves absolute paths alone, keeps a descriptor's class instances and functions, and the source's `load`, as the file built them (closures, prototypes and `this` survive), reports missing descriptors and descriptor field problems, family and target mismatches on target, adapter, driver and extensions, the removed `extensionPacks` key, contract, migrations and formatter problems, keeps fields the schema does not name on descriptors and on the contract source, and never throws on hostile input. `load.test.ts` still passes unchanged apart from the finalise module going away. - `@internal/cli`: `contract emit` and `migration plan` reached with `--config sub/prisma.config.ts` from the parent read and write under `sub/`, the plan test exercising the manifest walk from `baseDir`; the bin loader hands the engine the requested file with paths as written; ORM command tests seed the engine with a `prisma.config.ts` in the run directory through one shared helper so the engine validates the seed as it would a real file.

A config section schema now says which values the config file constructs, with
reference(schema). The command receives those values as the file's own objects, and every other value is copied before arktype writes resolved paths and defaults. This replaces the rule from #280, which guessed from a value's type: plain objects and arrays were copied, and everything else was kept.Changes
reference(schema)(packages/cli-engine/src/config-schema.ts): validates the value againstschemaand records it in the current validation's set of references. arktype runs these checks before it clones, and the clone the config scope supplies through arktype'scloneoption copies every value except the recorded references. A plain object the file built, such as a descriptor, keeps its identity only when it is declared a reference.pathor a default, because resolving one would write into the config file's own object.reference()refuses such a schema when it is defined: a schema that transforms has a different input expression (schema.in.expression !== schema.expression), which is public arktype API.packages/cli-engine/AGENTS.mdstate the rule.packages/cli/scripts/conformance.ts): every publish run onmainhas been failing its conformance check, which is why engine 0.6.1 never reached the registry. The dev channel installs each family's dev build, and@prisma/composer-cli@0.21.0-dev.4peers engine 0.5.0, while the recorded engine-transition exception named 0.4.0. The exception now also covers 0.5.0, until Composer releases against 0.6.1. The engine stays at 0.6.1, which was never published.Why
A value's type does not say whether the command needs the file's own object. The ORM's descriptors are plain objects, and the #280 rule copied them. Declaring references in the schema makes it explicit, in the one place that already declares the section's shape. Values not declared are copied whatever their type, so a schema author who forgets a declaration sees a copy in tests rather than a silent exception for some types.
Verified: engine 961 tests, CLI 1021 tests, lint, typecheck, error reference, grammar, and conformance on the release channel and on a locally reproduced dev-channel stamp (0 failing). prisma/orm#30372 will declare its descriptors with
reference().🤖 Generated with Claude Code
