TML-3233: emit Models namespace + models const; Scalars, Shape, and ResultType on ORM queries

[wmadden-electric]

Linked issue

Refs TML-3233 · Linear project Model and result types. Design: ADR 250.

At a glance

import type { models, Models } from '../prisma/contract';
import type { Scalars, Shape } from '@prisma/orm-postgres/family-contract/types';
import type { ResultType } from '@prisma/orm-postgres/components/runtime';

// Models types are directly available in two forms. This one is a bit nicer to type:
type User = typeof models.public.User;

// And the raw model type which doesn't require `typeof`:
type User2 = Models.public_User;

// A plain query returns the scalar form of the model, ie. all its properties without relations
type UserRow = Scalars<User>;

// But you often need a selection of your model properties and its relations. In Prisma 7 and below
// you'd use GetPayload<> for this. In Prisma 8, it looks like the following. Mark fields or
// relations for inclusion with `'+'`, or exclusion with `'-'`. Naming only relations in `'+'` keeps every scalar.
type UserResponse = Shape<User, {
  '-': 'passwordHash';
  posts: { '+': 'id' | 'title' | 'comments' };
}>; // { id; name; email; ...; posts: { id; title; comments: Scalars<Comment>[] }[] }

// This is useful in situations where you need to declare a type derived from your models, eg an
// API response type (real code: examples/prisma-8-demo/src/orm-client/get-user-profile.ts). TypeScript will then enforce that the result of your function, which will
// involve Prisma queries, matches the expected output shape. If you change the contract, the
// resulting shape will update.
export async function getUserWithPosts(id: string): Promise<UserResponse | null> {
  const user = await db.orm.public.User.where({ id }).include('posts', (p) => p.include('comments')).first();
  if (user === null) return null;
  const { passwordHash, ...rest } = user;
  return { ...rest, posts: user.posts.map(({ id, title, comments }) => ({ id, title, comments })) };
}

// And if you just want the exact type of a query you already wrote:
const usersWithPosts = db.orm.public.User.include('posts');
type UserWithPosts = ResultType<typeof usersWithPosts>;

Before this PR, contract.d.ts exported no model type, and ResultType returned never on ORM queries.

Summary

Two Prisma 7 users asked where Prisma.User and Prisma.BookGetPayload<{ include: { author: true } }> went. Prisma 8 had no answer: models were reachable only as FieldOutputTypes['public']['User'], and naming a query result meant NonNullable<Awaited<ReturnType<typeof q.first>>>. This PR gives users the model type, the scalar row a default fetch returns, a data structure derived from the model with picked or dropped scalars and nested relations, and the result type of any ORM query.

Skill update

skills/prisma-8/references/queries.md gains a "Naming model and result types" section and the routing table in skills/prisma-8/SKILL.md routes "type of my model", GetPayload, ResultType, Scalars, Shape, and Models prompts to it.

Decision

The model is the whole row plus its relations, as written in PSL. A query result is a view on it. Selection belongs to the query, not the model. ADR 250 records this. Concretely, this PR ships:

1. contract.d.ts emits export namespace Models with one member per model, the namespace folded into the member name (public_User, unbound_Audit; bare names on targets without namespaces), an Any<Base> union per polymorphic base, and export declare const models for dotted type-only access.
2. RelationKeys, Scalars<M>, and Shape<M, Spec> in framework-components, re-exported by both family contract packages. Shape takes an object spec: '+' keeps named scalars and relations, '-' drops scalars, any other key is a relation with a nested spec, and wrong names or '+' beside '-' are compile errors on the offending key (projects/model-and-result-types/shape-design-brief.md).
3. A _row phantom on both ORM collections so the existing ResultType works on ORM queries.
4. Type tests proving the ORM's rows equal Scalars and Shape of the emitted models (plain includes, projections, select plus include, nested includes, polymorphism) for SQL and for Mongo, and a demo test that declares an endpoint response with Shape and returns a transformed query result from a function with that return type.
5. Relation nullability is recorded on the contract. Every one-to-one and many-to-one relation carries nullable, set from the ? on the relation field in PSL or from the TypeScript builder, and read by the emitter and both ORMs. A contract written before this change loads unchanged: a missing flag is derived at hydration from the foreign-key columns' storage nullability, and a present flag is checked against storage on load. The emitter requires the flag on the contracts it consumes. The storage-plane reconstruction in the ORM types and the emitter hook that mirrored it are gone.
6. Every emitted fixture regenerated, a reference page, and the user skill update.

Reviewer notes

• The largest diff is fixture regeneration: every emitted contract.d.ts in the repo gains the Models block, including the 204 port fixtures and the migration snapshot stores that pnpm fixtures:check did not cover before. The check now covers them through test/integration/scripts/emit-fixture-configs.mjs and scripts/refresh-contract-snapshot.mjs. 143 contract.json files change, and every changed line is the _generated banner, which those stale fixtures had never picked up. Spot-check packages/3-extensions/sql-orm-client/test/fixtures/generated/contract.d.ts and the polymorphism fixture under test/integration/test/sql-orm-client/fixtures/polymorphism/.
• A default fetch returns Scalars<Model>, not the model. This is the opposite of Prisma 7, where the generated User is scalars-only, and the reference page says so in its first paragraph.
• The namespace is in the member name wherever a collision is possible: on Postgres a default-schema model is Models.unbound_User, because public.User can sit beside it, matching db.enums and the contract views. A target whose descriptor declares namespaceSupport: 'none' (SQLite) emits bare names, Models.User and models.User. The choice is a declared target capability, never a count of the namespaces in a particular contract.
• A relation whose target is a polymorphic base is emitted as the Any<Base> union, because that is what the ORM returns for such includes.
• Relation nullability comes from the schema, not storage. author User? gives nullable: true, author User gives false; authoring rejects a required relation field over a nullable foreign key and the reverse. The side of a one-to-one that does not own the foreign key is always nullable, in PSL and in the builder, because nothing guarantees the related row exists. A refined to-one include is | null regardless, because the refinement can exclude the row.
• Mongo follows the schema too. Its ORM used to type every to-one include as | null; now it reads the flag. A required reference whose document is missing comes back with the key absent at runtime, which the type no longer admits. That is a general read-time concern on Mongo, recorded in projects/model-and-result-types/deferred.md, not changed here.
• contract.json gains one boolean per to-one relation. The domain section is canonicalized as empty for the storage hash, so no contract hash changes, and migration snapshots written before this change still load because a missing flag is derived at hydration. Seven ported .prisma schemas had an optional relation field over a required foreign key, which authoring now rejects; the ? was removed and no emitted type changed.
• The to-one nullability rule lives once, in @internal/contract-authoring, and the two PSL interpreters and two TypeScript builders call it. Scalars and RelationNamesOf infer the relation keys without a constraint fallback so they work in projects without exactOptionalPropertyTypes; a test compiles the fixture with that flag off.
• Mongo embedded models carry no RelationKeys phantom, so Scalars of an owner's embed field equals the ORM's embed row.
• Shape flattens each level so toEqualTypeOf can compare it with ORM rows and hover text shows one object.
• Adjacent fixes in the second commit: examples/prisma-8-demo now passes pnpm lint (every bare throw uses a named Error subclass from src/errors.ts or TypeError), and the no-bare-cast, no-bare-throw, and no-family-vocabulary plugins exclude .test.tsx, .test.mts, and .test.cts the same way they exclude .test.ts. Forty orphan contract.* copies under relation-mode-gh-* fixtures, produced by an older emit and referenced by nothing, are deleted.
• Left as they are, with reasons in the commit: two hand-authored minimal contract.d.ts test inputs, two telemetry-backend snapshots whose PSL no longer exists, 44 snapshots under examples/prisma-8-demo/fixtures/*/migrations that no script produces, and two vendored extension snapshots whose refresh belongs to the extension install flow.
• Pre-existing flakes, not caused here: @prisma/orm-framework test/module-identity.test.ts races on pnpm pack's skill sync and passes on rerun; driver-adapters-error-forwarding › correctly forwards error for queryRaw is a test.fails port that now passes, identically with the old fixture restored.
• This PR is also the project's close-out: the transient artifacts under projects/model-and-result-types/ are deleted in the last commit, ADR 250 and the reference page are the durable record, the final retro is in drive/retro/findings.md, and every deferred item has a Linear issue (TML-3235, 3236, 3237, 3242 to 3246).

How it fits together

1. Framework types. packages/1-framework/1-core/framework-components/src/execution/model-types.ts declares the RelationKeys unique symbol and the two utilities. Both are distributive, so they work on Any<Base> unions. Shape validates the spec through a mapped constraint over the spec's own keys and reads each relation's wrapper from the model's own field type.
2. Emission. packages/1-framework/3-tooling/emitter/src/model-types-emission.ts renders the block from contract.domain, sharing the field-type resolver with FieldOutputTypes via resolveModelFieldType, and reads each to-one relation's nullable for the | null wrapper. Name collisions, non-identifier names, and unresolvable same-space relation targets throw structured errors before anything is written.
3. ORM phantoms. One declare readonly _row?: Row line on CollectionImpl and one readonly _row?: SimplifyDeep<IncludedRow<...>> member on MongoCollection.
4. Proof. Type tests in both ORM packages and the demo assert equality between the ORM's rows and the emitted types for every fixture model, every cardinality, polymorphic roots and variants, projections, nested and refined includes, and every Shape refusal as a @ts-expect-error.
5. Docs. docs/reference/model-and-result-types.md, with every snippet copied from a passing type test; ADR 250; the subsystem doc paragraph; README links; the user skill.

Testing performed

• pnpm build (root)
• pnpm test:packages (1186 files; one pre-existing race in module-identity.test.ts, passes on rerun)

• pnpm test:integration (372/373 files; the one failure is the pre-existing test.fails port noted above)
• pnpm lint:casts, pnpm lint:throws, pnpm lint:framework-vocabulary

Follow-ups

• Rename ResultType to Result (open question in the brief; not done here).
• Scalars versus Row naming, and the _ separator, are open in the brief and can be changed before release.

Alternatives considered

• Emit GetPayload-style types per query. Ties the contract to one lane's vocabulary and grows contract.d.ts without bound.
• With<M, 'rel'>, a model plus a union of relation names. The first draft. Replaced by Shape before merge: it could not drop or narrow scalars or nest, so an endpoint response still needed hand-written types. With<User, 'posts'> is Shape<User, { posts: {} }>.
• Prisma 7's boolean form, { id: true; posts: { title: true } }. Verbose: every scalar must be listed for the wide case. '+'/'-' sigils were chosen over words because words collide with field names.
• A relation-selection parameter on the contract, Model<Contract, 'User', { posts: { comments: true } }>. Takes the contract rather than the model and reads as a query. Shape is a pure utility over the model type and describes end states, not queries.
• A parameter mapping relation name to the model type that sits there. Makes the user import and restate what the contract already knows.
• Models.public.User as nested TypeScript namespaces. namespace public does not compile; public is reserved in strict mode and is the default Postgres schema. Folding the schema into the member name gives the importable form; the declared constant gives the dotted form.
• Flat export type User at the top level. Adding a second User in another schema would silently remove the alias and break every import of it.
• A runtime db.models accessor. Either an object pretending to be a row or a definition object whose typeof is not the model. Dotted access already exists with no runtime.
• A separate RowOf helper for ORM queries. ResultType exists and is documented; the collections now carry the marker it reads.

Make the RelationKeys import requirement explicit in EmissionSpi.

generateModelTypesBlock emits readonly [RelationKeys]?: ... for models without an owner. generate-contract-dts.ts only inserts the strings returned by getFamilyImports. The current SQL and Mongo implementations include RelationKeys, but the EmissionSpi contract does not enforce this requirement. Add a framework-level assertion or move this import responsibility into the framework to prevent future emitters from generating uncompilable .d.ts files.

Drop the not.toBeNever() assertion in the rejection test.

The @ts-expect-error on Line 201 is the assertion that proves With rejects a non-relation key. Line 203 then asserts a property of Bad, which is the resolution of an instantiation the test just declared invalid. That resolution is incidental. If With later resolves a rejected key to never, this test fails even though the rejection contract still holds.

The equivalent framework test in packages/1-framework/1-core/framework-components/test/model-types.test-d.ts (Lines 98-103) declares the invalid aliases without a follow-up assertion. Align this test with that shape.

contract.md:
- Line 21: Update the usersWithPosts example to use the documented ORM accessor
by replacing both db.User references with db.orm.User, using db.orm.public.User
where namespace qualification is required.

In `@docs/reference/query-patterns.md`:
- Line 74: Rewrite the sentence around ResultType so it distinguishes the
generated Models namespace from the separate Scalars and With utility exports;
state that Models names generated model rows and is used together with Scalars
and With for rows without a query in scope, preserving the existing ResultType
explanation and reference link.

In
`@packages/1-framework/1-core/framework-components/src/execution/model-types.ts`:
- Around line 26-33: Update the With type alias to distribute over each union
member of M, mapping only Extract<R, keyof M> for that member so
variant-specific relations retain their item types instead of resolving through
shared keyof M. Add a type test covering two polymorphic variants with distinct
relation names.

In `@packages/1-framework/3-tooling/emitter/src/model-types-emission.ts`:
- Around line 191-194: Update memberLines and the fieldLines emission flow to
key field entries by field name before constructing the generated fields array,
so variant fields replace same-named base fields instead of producing duplicate
members. Introduce or reuse a fieldEntries helper as needed, preserving the
existing emission order and behavior for unique fields.
- Around line 283-285: Update the variant handling around variantMembers and
validate each variant name with validateContractDomain before emitting
Any<Base>; when validation fails, emit the established structured error and
prevent the undeclared variant type from being generated.

In `@skills/prisma-8/references/queries.md`:
- Line 131: Update the query result type wording near the default fetch examples
to distinguish the row type from the collection result: describe Scalars<Model>
as the row type, state that first() returns Scalars<Model> | null, and state
that await ...all() returns Scalars<Model>[].
- Line 157: Update the Mongo query guidance to import CreateInput,
VariantCreateInput, and MongoWhereFilter from the Mongo ORM module, while
retaining MutationUpdateInput and ShorthandWhereFilter from the PostgreSQL ORM
client guidance. Preserve the existing Mongo distinction that embedded documents
remain in Scalars and avoid recommending fully loaded nested model projections.

In `@docs/onboarding/fixtures-emit-and-check.md`:
- Around line 9-12: Update the fixture-config description in the onboarding
documentation to state that emit-fixture-configs.mjs re-emits only
prisma.config.ts files with a committed generated/ sibling, rather than every
configuration file. Also clarify that both migrations:regen and
migrations:regen:examples replace stale snapshots when either contract.json or
contract.d.ts differs, using refreshContractSnapshot.

In `@test/integration/test/ports/README.md`:
- Line 45: Update the fixture emitter scope statement to clarify that emit
processes each prisma.config.ts only when its sibling generated/ directory
exists; configs without a committed generated/ directory are skipped.

104-104: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add type-level assertions for the belongsTo option combinations. options: object prevents the spread object from selecting the BelongsToOptions overload, so Nullable is inferred as undefined. The runtime assertions do not check the resulting ToOneRelationNullable or ContractRelationFromBuilder type. Add assertions for required, optional, and explicit-flag cases.

at line 104, Add type-level assertions around the belongsTo builder cases,
ensuring required, optional, and explicit-flag option combinations infer the
expected ToOneRelationNullable and ContractRelationFromBuilder types. Update the
belongsTo helper’s options typing from object so spread options select the
BelongsToOptions overload and Nullable is inferred correctly; preserve the
existing runtime assertions.

In `@packages/2-mongo-family/2-authoring/contract-psl/src/interpreter.ts`:
- Line 1163: Update the nullability-mismatch handling around
PSL_RELATION_NULLABILITY_MISMATCH to track invalid FK pairings separately,
including their relation name. When evaluating inverse candidates for
PSL_ORPHANED_BACKRELATION, suppress the diagnostic for the matching tracked
pairing, while keeping invalid relations out of metadata and allFkRelations.

In `@packages/2-mongo-family/2-authoring/contract-ts/src/contract-builder.ts`:
- Around line 1581-1583: Validate every entry in on.localFields against fields
before deriving to-one nullability, rejecting any undeclared local
field—including inherited base-field names. Update the validation logic near
anyLocalFieldNullable so invalid references produce an authoring error, while
preserving the existing nullable derivation for declared fields.

In `@packages/2-mongo-family/5-query-builders/orm/src/types.ts`:
- Around line 167-169: Update IncludeRelationRowType’s nullable conditional so
only an explicit nullable: false produces a non-null row; treat nullable: true
and widened nullable: boolean relations as InferFullRow<TContract, To> | null,
preserving the existing row inference.
