Codecs own the PSL form of literal defaults (remove-dbgenerated slice B)

[wmadden-electric]

Linked issue

Refs: no Linear ticket. Prerequisite: the project shaping PR #30327 (this branch rebases onto main once it merges). Slice B of the "Remove dbgenerated(...)" project, spec at projects/remove-dbgenerated/slices/b-codec-psl-literals/spec.md. Slice A (the sql\...`tagged literal) runs in parallel; slice C (deletingdbgenerated`) follows both.

At a glance

This schema now emits, migrates, verifies clean under db verify --schema-only --strict, and reads back with the codec's own types (from test/integration/test/cli-journeys/codec-psl-literal-defaults.e2e.test.ts):

model T {
  id     Int     @id @default(autoincrement())
  meta   Jsonb   @default("{}")
  items  Json    @default("[1, 2]")
  big    BigInt  @default(9007199254740993)
  price  Decimal @default(1.50)
  ratio  Float   @default("NaN")
  name   String  @default("x")
  flag   Boolean @default(true)
  scores Int[]   @default([1, 2])
}

expect(await rows(runtime.query(plan))).toEqual([
  { id: 1, meta: {}, items: [1, 2], big: 9007199254740993n, price: '1.50', ratio: Number.NaN, name: 'x', flag: true, scores: [1, 2] },
]);

Before this change, Jsonb @default("{}") stored the string "{}" rather than the JSON object, Bytes @default(1234) crashed the interpreter, and contract infer printed timestamp and JSON defaults as dbgenerated(...).

Decision

Every codec owns the PSL form of its literals. encodePsl and decodePsl are required members of the framework Codec interface and abstract on CodecImpl, so no codec's PSL form is implicit. The three places that read or print a literal default now call the column codec instead of branching on type:

1. The Prisma 8 PSL interpreter (@default(...) literal arms) reads through decodePsl and reports PSL_INVALID_DEFAULT_LITERAL with the codec's message.
2. The Prisma 7 contract source reads through decodePsl; its whole-number rule, JSON-string parsing, and number heuristics are gone.
3. The contract infer printer prints through encodePsl; the per-type formatter table is gone.

This is the PSL half of ADR 184, amended in this PR (docs/architecture docs/adrs/ADR 184 - Codec-owned value serialization.md). The DDL half stays future work.

Reviewer notes

• Largest commits. e4052073b5 touches 46 test files because about forty test doubles implement Codec as object literals; each gained the two members through the shared helpers. Spot-check packages/2-mongo-family/1-foundation/mongo-codec/src/codecs.ts (the factory now requires both members) and one defineTestCodec helper.
• Float NaN/Infinity on Postgres. pg/float4@1 and pg/float8@1 now carry non-finite values as the text NaN, Infinity, -Infinity in JSON and on the wire, and read them back as numbers. Before, the contract stored the string and the runtime cast it as a number without converting. Contract JSON for existing contracts is unchanged (a non-finite float had no valid JSON number form before either).
• pg/numeric@1 reads two forms, writes one. It reads a number literal (1.50, 007 canonicalised to 7) and a quoted decimal string ("1.50", the form older schemas and the old printer used), and always prints a number literal. The three special values print quoted.
• Infer now prints temporal defaults as literals. '2024-01-01 00:00:00'::timestamp prints @default("2024-01-01T00:00:00"), and a timestamp list prints as a literal list; the Prisma 7 defaults journey proves those emit, migrate, and verify clean. Defaults the codec cannot read (NULL::character varying) still fall back to dbgenerated(...) until slice C.
• Mongo codecs are built by a factory, not classes. The spec assumed classes; the mongoCodec factory config requires the two members instead, with no default in the factory.
• Spec deviations, each recorded in the slice plan. Codec resolution in the printer keys on the printed PSL type name (several codecs share the timestamptz native type); enum columns print through pg/text@1.
• Project artefacts on disk. projects/remove-dbgenerated/ is transient and carries the project spec, this slice's spec and plan. Slice C's close-out deletes it.
• Slice A rebase. Both slices edit scalarDefaultArms in packages/2-sql/2-authoring/contract-psl/src/sql-attribute-specs.ts. This PR replaced the three literal arms with one literal() arm; slice A appends a tagged-literal arm after the function arms. Whichever merges second resolves that one function by hand.

How it fits together

1. Framework. PslLiteral ({ kind: 'string' | 'number' | 'boolean', text }, fence removed, escapes resolved, digits verbatim) and the two required Codec members live in packages/1-framework/1-core/framework-components/src/shared/. Shared helper pairs for the common shapes are in psl-literal-helpers.ts. The PSL parser gains a literal() attribute-spec combinator that produces a PslLiteral.
2. Codecs. One rule keyed on the JSON form: string JSON form → string literal, number → number literal with no exponent, boolean → boolean, object/array/null → string literal holding JSON text. Named exceptions: Postgres floats (quoted specials), big integers and numeric (digits as text, never through a JavaScript number), integer codecs reject a fraction, sql/float@1 and sqlite/real@1 refuse non-finite values. Codecs whose JSON form is a string but whose value is not (bytea, geometry, interval, Temporal, Date) carry encodeJson/decodeJson inside a string literal.
3. Interpreter. lowerDefaultForField in packages/2-sql/2-authoring/contract-psl/src/psl-column-resolution.ts decodes each literal through the column codec; number-literal-default.ts and the numeric trait check are deleted.
4. Prisma 7 source. packages/2-sql/2-authoring/contract-prisma7/src/defaults.ts builds a PslLiteral per expression and decodes through the codec; the json literal form is gone from the target binding. The sqlExpression form for bytea and temporal columns stays (DDL side out of scope).
5. Printer. mapDefault(columnDefault, { codec }) in the SQL family prints formatPslLiteral(codec.encodePsl(codec.decodeJson(value))); the Postgres printer resolves the codec contract emit binds to the printed type name and falls back to the raw expression when the codec cannot read the value.
6. Proof. Two journeys: the jsonb default in the infer round-trip journey no longer needs a workaround, and the new journey above covers every literal kind end to end.

Behavior changes & evidence

• Jsonb/Json @default("...") stores the parsed JSON value; Json @default("null") stores JSON null. packages/2-sql/2-authoring/contract-psl/src/psl-column-resolution.ts; evidence packages/2-sql/2-authoring/contract-psl/test/interpreter.defaults.test.ts, packages/3-targets/6-adapters/postgres/test/psl-interpreter-literal-defaults.test.ts.
• A literal the codec cannot read (Int @default(1.5), Int @default("1"), Bytes @default(1234)) is PSL_INVALID_DEFAULT_LITERAL at the attribute, with the codec's message, instead of a wrong value or a crash. Evidence: the same two tests and test/integration/test/number-defaults/psl-number-defaults.integration.test.ts.
• Prisma 7 Int @default(1.5) and Json @default("{\"a\":1}") go through the codec; messages now read is not a value of <codecId>: .... packages/2-sql/2-authoring/contract-prisma7/src/defaults.ts; evidence packages/2-sql/2-authoring/contract-prisma7/test/defaults.test.ts and the integer-default-not-whole-number fixture.
• contract infer prints numeric defaults as number literals, JSON defaults as JSON text, big integers with every digit, floats' specials quoted, and temporal defaults as the codec's ISO form. packages/2-sql/9-family/src/core/psl-contract-infer/default-mapping.ts, packages/3-targets/3-targets/postgres/src/core/psl-infer/infer-model-blocks.ts; evidence packages/3-targets/3-targets/postgres/test/psl-infer/print-psl/print-psl.literal-defaults.test.ts, test/integration/test/cli-journeys/infer-roundtrip-fidelity.prisma7-defaults.e2e.test.ts.
• Every codec in the repository round-trips decodePsl(encodePsl(v)) and rejects a wrong-kind literal with a message naming the codec. Evidence: psl-literals.test.ts in the Postgres, SQLite, pgvector, postgis, arktype-json, and Mongo adapter test folders.
• @default( completions on a Boolean field still offer true/false (a regression caught by the packages suite and fixed). packages/1-framework/3-tooling/language-server/src/completion-values.ts.

Compatibility / migration / risk

• No contract format change: pnpm fixtures:check shows every existing contract.json byte-identical.
• Codec authors, including extension authors, must implement encodePsl and decodePsl; a codec class without them no longer compiles. The codec authoring guide shows a string-valued and a JSON-valued example.
• Behaviour change for schemas: a number literal on a column whose codec does not hold numbers (Bytes @default(1234)) is now a diagnostic instead of a stored number.

Testing performed

• pnpm typecheck (169/169), pnpm lint (101/101), pnpm lint:deps, pnpm lint:docs, pnpm check:error-reference
• pnpm test:packages (17282 tests; one mongodb-memory-server port-collision flake in target-mongo, green in isolation)
• pnpm test:integration (392 files, 2160 tests; two afterAll teardown timeouts under load on the first run, green on re-run and in isolation)
• pnpm test:e2e (22 files, 116 tests)
• pnpm fixtures:check (every contract.json byte-identical)
• Grep gates: numberLiteralDefault|PslDefaultValueFormat|formatLiteralValue and kind: 'json' in the Prisma 7 source return nothing.

Skill update

Extension authors: upgrade-instructions/pending/codec-psl-literals/extension/instructions.md records the two new required codec members and the helper pair to pick by JSON form; pnpm check:upgrade-coverage --mode pr passes. For user-facing skills, n/a: the PSL syntax for literal defaults is unchanged; what changed is which values are accepted and how infer prints them. The codec authoring guide (docs/reference/codec-authoring-guide.md) and packages/2-sql/2-authoring/contract-psl/README.md are updated for codec and schema authors.

Follow-ups

• Slice C: delete dbgenerated(...), the printer's raw-expression fallback, and the // Raw default: comment result. The DDL methods (encodeDdl/decodeDdl) stay deferred; the ADR amendment records the consequence inline.
• The printer's PSL-type-name → codec-id map in packages/3-targets/3-targets/postgres/src/core/psl-infer/infer-default-codec.ts duplicates a binding the adapter owns, forced by layering (a target cannot import its adapter).

Alternatives considered

• A separate PslLiteralCodec registry keyed by codec id (the ADR 184 sketch). Rejected: the PSL form is part of what owning a type means, and a second registry would hold the same information in a second place; the sketch is the consumer's view of the same codec.
• A base-class default for encodePsl/decodePsl. Rejected: the methods are required so that no codec's PSL form is implicit; the shared helpers make each implementation one line.
• Converting number literals to a JavaScript number before the codec sees them. Rejected: it loses precision for big integers and decimals; the codec receives the digits as written.
• Deriving the Mongo factory's PSL pair from its JSON pair. Rejected for the same "no implicit form" reason; the factory requires both members.

Inline comments:
In `@packages/2-mongo-family/1-foundation/mongo-codec/README.md`:
- Line 7: Update both mongoCodec() examples in the README to include valid
encodePsl and decodePsl members, matching the required codec configuration shape
while preserving each example’s existing behavior.

In `@packages/2-sql/2-authoring/contract-psl/test/interpreter.enum.test.ts`:
- Around line 58-59: Update the int4Codec PSL conversion methods so encodePsl
emits the numeric representation and decodePsl parses only valid numeric PSL
literals, rejects other literal kinds or invalid values, and returns the codec’s
numeric input type instead of raw text. Ensure the enum default resolver
receives a number while preserving the existing codec contract.

In `@packages/2-sql/4-lanes/relational-core/README.md`:
- Line 96: Add encodePsl and decodePsl implementations to the adjacent
PgTextCodec example, using string PSL serialization and deserialization
consistent with the codec’s other methods. Update the listed synchronous
build-time methods to include both PSL methods alongside encode, decode,
encodeJson, and decodeJson.

In `@packages/2-sql/4-lanes/relational-core/src/ast/sql-codecs.ts`:
- Around line 122-124: Update SqlIntCodec.encodePsl to validate that value is a
whole number before calling encodeNumberPsl, using the same whole-number
validation or codec-specific diagnostic expected by decodePsl and preserving
encoding for valid integers.

In `@packages/2-sql/4-lanes/relational-core/test/ast/test-codec.ts`:
- Around line 53-57: Update defineTestCodec’s PSL encoding and decoding helpers
to use a single string representation: encode string JSON values through
encodeJsonTextPsl, and keep decodePsl using decodeJsonTextPsl for string
literals so composite objects and arrays are decoded rather than returned as
source text. Preserve the existing number and boolean handling.

In `@packages/3-mongo-target/2-mongo-adapter/src/core/codecs.ts`:
- Line 40: Update decodePsl to validate the decoded string using the same
ObjectId validity rules enforced by encode before returning it. Ensure invalid
literals such as non-ObjectId text produce the codec diagnostic, while valid
ObjectId text retains the existing decode behavior.
- Around line 63-64: Update the encodePsl and decodePsl paths in the codec
definition to enforce the signed Int32 domain: reject non-whole or out-of-range
values before encoding, and validate decoded values after decodeWholeNumberPsl
before returning them. Preserve fractional support in encodeNumberPsl for other
codecs while ensuring this Int32 codec accepts only whole values within the
signed Int32 range.
- Line 81: Update mongoDateDecodeJson to validate the Date created from decoded
text by checking date.getTime(); when it is NaN, throw mongoAdapterError with
the RUNTIME.DECODE_FAILED code, while preserving the existing return for valid
dates.

In `@packages/3-targets/3-targets/postgres/src/core/codecs.ts`:
- Line 598: Update the decode path around decodeJsonTextPsl and decodeJson to
validate that the parsed literal is an array containing only strings before
returning it. Reject non-array values and arrays with non-string elements
through the codec diagnostic path, while leaving decodeJson’s permissive
behavior unchanged.

In `@packages/3-targets/3-targets/sqlite/src/core/codecs.ts`:
- Around line 332-336: Update encodePsl and decodePsl to validate values with
Number.isSafeInteger before encoding and before converting decoded literals to
number. Reject non-integral or unsafe values consistently, while preserving the
existing encodeNumberPsl and decodeWholeNumberPsl flow for valid safe integers.

In `@packages/3-targets/6-adapters/postgres/test/test-codec.ts`:
- Around line 53-56: Update the string-handling branch in both decodePsl
helpers—packages/3-targets/6-adapters/postgres/test/test-codec.ts:53-56 and
test/integration/test/cross-package/test-codec.ts:53-56—so encodePsl uses
encodeJsonTextPsl(json) for string values, matching decodeJsonTextPsl and
preserving correct JSON-text round trips.

Use numeric PSL conversion for int4Codec.

Codec.decodePsl must return the codec's input type and reject literals that are not valid values of that type. int4Codec.decodeJson accepts numbers, but its PSL pair returns raw text and accepts every literal kind. The current enum default assertion resolves the member value directly, so it does not exercise these methods. The fixture still violates the codec contract and can supply a string where the column-default resolver expects a numeric input.

Proposed fix

-import type { Codec, CodecLookup } from '`@internal/framework-components/codec`';
+import {
+  decodeWholeNumberPsl,
+  encodeNumberPsl,
+  type Codec,
+  type CodecLookup,
+} from '`@internal/framework-components/codec`';

-  encodePsl: (value) => ({ kind: 'string', text: String(value) }),
-  decodePsl: (literal) => literal.text as never,
+  encodePsl: (value) => encodeNumberPsl(value as number),
+  decodePsl: (literal) => Number(decodeWholeNumberPsl('pg/int4@1', literal)),

Add the PSL methods to the codec example.

The text now requires encodePsl and decodePsl, but the adjacent PgTextCodec example omits both methods. The example no longer shows a complete CodecImpl implementation.

Add string PSL encoding and decoding to PgTextCodec. Also list the PSL methods with the synchronous build-time methods.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a whole-number check to SqlIntCodec.encodePsl.

encodePsl does not validate that value is a whole number before encoding it. decodePsl on the same class enforces this through decodeWholeNumberPsl, and SqlFloatCodec.encodePsl enforces its own type constraint (finiteness) symmetrically before encoding. Without a matching check here, a fractional number (for example 1.5) silently produces a PSL literal that reads back as invalid on an Int field, instead of raising a codec-specific diagnostic.

🐛 Proposed fix

   encodePsl(value: number): PslLiteral {
+    if (!Number.isInteger(value)) throw new Error(`${this.id} writes a whole number; got ${value}`);
     return encodeNumberPsl(value);
   }

Use one string PSL representation in defineTestCodec.

PslLiteral does not distinguish raw string text from JSON text. encodeJsonTextPsl emits kind: 'string' for composite JSON values, so the proposed unconditional string branch would return the JSON source text instead of the decoded object or array.

Encode string JSON values with encodeJsonTextPsl and keep decodePsl on decodeJsonTextPsl:

-    if (typeof json === 'string') return { kind: 'string', text: json };
+    if (typeof json === 'string') return encodeJsonTextPsl(json);

The current relational-core callers do not invoke these PSL methods, so this is a latent test-helper correctness issue rather than a currently failing workflow.

Enforce the Int32 value domain on both PSL paths.

encodeNumberPsl must support 1.5 for mongo/double@1, so this encoder emits a fractional literal that this decoder rejects. The decoder also accepts whole values outside signed Int32 range. Validate whole signed Int32 values before encoding and after decoding.

Reject invalid date text.

For a string such as "x", mongoDateCodec.decodePsl passes the decoded text to mongoDateDecodeJson, where new Date(json) returns Invalid Date without throwing. Check date.getTime() and throw mongoAdapterError('RUNTIME.DECODE_FAILED', ...) when it is NaN. This structured error matches the codec runtime contract.

Reject invalid pg/text-array@1 literal shapes.

decodeJsonTextPsl can return any JSON value. The subsequent decodeJson call converts {} to [] and [1] to ['1']. A malformed text-array default therefore becomes a different valid value instead of producing a codec diagnostic.

Validate that the parsed value is an array of strings before returning it. Do not tighten decodeJson if its permissive runtime behavior must remain compatible.

Proposed fix

   decodePsl(literal: PslLiteral): readonly string[] {
-    return this.decodeJson(decodeJsonTextPsl(this.id, literal));
+    const value = decodeJsonTextPsl(this.id, literal);
+    if (!Array.isArray(value) || value.some((entry) => typeof entry !== 'string')) {
+      throw pslLiteralReadsError(
+        this.id,
+        'a string literal holding a JSON array of strings',
+        literal,
+      );
+    }
+    return value;
   }

Align string encoding with decodeJsonTextPsl in both helpers.

encodePsl writes string values as raw PslLiteral.text, but decodePsl parses every string with JSON.parse. Therefore, "abc" throws, while "null" and "123" become null and 123. Encode string values with encodeJsonTextPsl(json) so the encoder and decoder use the same JSON-text representation.

Preserve signed zero in numeric literals.

decodeNumberPsl and decodeFloatPsl preserve -0 when they read -0. String(-0) then converts it to "0", so re-encoding changes the literal. This violates the ADR’s exact decimal-text rule for these number codecs. The pg/numeric@1 canonicalisation is codec-specific and does not apply to this shared helper.

Proposed fix

 export function encodeNumberPsl(value: number): PslLiteral {
+  if (Object.is(value, -0)) return { kind: 'number', text: '-0' };
   const [coefficient = '', exponent] = String(value).split('e');

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	const [coefficient = '', exponent] = String(value).split('e');
	if (Object.is(value, -0)) return { kind: 'number', text: '-0' };
	const [coefficient = '', exponent] = String(value).split('e');

Encode string PSL values as JSON text. encodePsl stores string values without JSON quoting, but decodePsl passes every string literal to decodeJsonTextPsl, which calls JSON.parse. Therefore, decodePsl(encodePsl('plain')) throws. Return encodeJsonTextPsl(json) for string values so the value round-trips correctly.

Preserve scalar JSON arrays as one literal.

Line 61 treats every JavaScript array as a SQL list default. A scalar Json or Jsonb default can also be an array. This path then encodes each JSON element separately and emits a PSL list instead of one JSON string literal.

Pass the column cardinality into mapDefault. Only map array elements when the column is a list.

Proposed change

 export interface LiteralDefaultMappingOptions extends DefaultMappingOptions {
   readonly codec: Codec;
+  readonly isList: boolean;
 }

-      return { attribute: `@default(${formatLiteral(columnDefault.value, options.codec)})` };
+      return {
+        attribute: `@default(${formatLiteral(columnDefault.value, options.codec, options.isList)})`,
+      };

-function formatLiteral(value: ColumnDefaultLiteralInputValue, codec: Codec): string {
+function formatLiteral(
+  value: ColumnDefaultLiteralInputValue,
+  codec: Codec,
+  isList: boolean,
+): string {
   const literal = (element: ColumnDefaultLiteralInputValue) =>
     formatPslLiteral(
       codec.encodePsl(element instanceof Date ? element : codec.decodeJson(element)),
     );
-  return Array.isArray(value) ? `[${value.map(literal).join(', ')}]` : literal(value);
+  return isList && Array.isArray(value)
+    ? `[${value.map(literal).join(', ')}]`

Use JSON-text encoding for JSON string values.

encodePsl writes a JSON string as raw text. decodePsl then parses that text with decodeJsonTextPsl. A value such as "abc" fails to decode, while "null" can decode as null.

Use encodeJsonTextPsl(json) for the string branch.

Proposed fix

-    if (typeof json === 'string') return { kind: 'string', text: json };
+    if (typeof json === 'string') return encodeJsonTextPsl(json);

Validate PostgreSQL integer ranges in both PSL directions.

PgInt4Codec and PgInt2Codec pass fractional values to encodeNumberPsl, which accepts them. Their decodePsl methods only call decodeWholeNumberPsl and Number(). The helper checks integer syntax, but it does not check PostgreSQL bounds or safe-number precision.

No caller adds these checks before decoding. PSL default resolution retains the decoded value. Therefore, @default(32768) can be accepted for pg/int2@1, and @default(2147483648) can be accepted for pg/int4@1. Text beyond the safe-integer range can also lose precision during Number() conversion. Contract-to-PSL inference can emit fractional or out-of-range integer defaults instead of rejecting them.

Use a shared PSL integer validator with the PostgreSQL bounds for each codec: [-32768, 32767] for pg/int2@1 and [-2147483648, 2147483647] for pg/int4@1. Apply it before encodeNumberPsl and after reading the whole-number text, before converting it with Number(). A safe-integer-only check is not sufficient because the PostgreSQL ranges are narrower.

Closing: the codec encodePsl/decodePsl design this PR implements is replaced by ADR 253 (#30334), where codecs declare the literal types they are compatible with. The branch stays for reuse of the end-to-end default journeys, the float and decimal codec fixes, and the printer's codec lookup.
