From b0b24d3313ceee088f923f164833891e6c020531 Mon Sep 17 00:00:00 2001 From: willbot Date: Thu, 17 Sep 2026 16:47:45 +0200 Subject: [PATCH 01/81] docs(adr): ADR 253, column defaults have a literal type that codecs declare A literal column default has a literal type: string, number, boolean, or json. A codec descriptor declares the literal types its columns are compatible with, with read and write functions only where the codec JSON form differs from the literal value. PSL writes a literal as a plain scalar or as a tagged literal such as json`{}`; the sql tag writes a raw SQL expression instead. Codecs never see PSL syntax. ADR 253 replaces the PSL half of ADR 184. The remove-dbgenerated project spec amends D9 and D10 to match, the plan runs slice B after slice A, and the slice B spec is marked superseded until it is rewritten.

The JSON half of ADR 184 is unchanged. + +## Why literal types + +### A codec cannot be asked "is this literal yours?" without a type to answer about + +In SQL a codec can represent almost anything: a number, a document, a geometry, a vector, a timestamp. When a schema writes a default, something has to decide whether the written value suits the column. If the only information available is the characters the author typed, the codec has to try to read them and report failure by throwing. That makes compatibility a side effect of decoding, and the error the author sees is whatever the codec happened to throw. + +A literal type turns the question into a lookup. The literal says what kind of value it is. The codec says which kinds it accepts. A mismatch is reported before anything is decoded, with a message that names the codec and the literal types it accepts. + +### A codec should not depend on PSL + +Codecs live below every authoring surface. PSL is one surface; the schema language of earlier Prisma versions, read by the contract source in [ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md), is another. If a codec received PSL text, or the PSL parser's idea of what a token is, every codec would be coupled to PSL's quoting, escaping, and tokenizer rules. A change to PSL syntax would become a change to every codec. + +With literal types, each authoring surface maps its own syntax to literals, and codecs only ever receive a literal of a type they declared. PSL can gain new tags without any codec changing. + +### One literal type means different things to different codecs + +The contract stores a literal default in the column codec's JSON form ([ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md)). Those forms are chosen by each codec, so the same literal lands differently: + +| Column | Codec | Written | Stored in `contract.json` | +|---|---|---|---| +| `Int` | `pg/int4@1` | `42` | `42` | +| `BigInt` | `pg/int8@1` | `9007199254740993` | `"9007199254740993"` | +| `Decimal` | `pg/numeric@1` | `1.50` | `"1.50"` | + +All three are `number` literals. The literal type alone cannot choose between a JSON number and decimal text, and existing contracts must keep their JSON forms. So the conversion from a literal's value to the JSON form belongs to the codec, and the codec declares it together with the literal types it accepts. + +## Literal types + +A literal type defines what its value is, independently of how any authoring surface writes it. + +| Literal type | Value | Written in PSL as | +|---|---|---| +| `string` | The text, with escapes resolved | A string scalar: `"anonymous"` | +| `number` | The number exactly as written, kept as text: `1.50`, `9007199254740993`, `-7`, `NaN`, `Infinity` | A number scalar: `1.50` | +| `boolean` | `true` or `false` | A boolean scalar: `true` | +| `json` | A JSON value | A tagged literal: `` json`{ "plan": "free" }` `` | + +Two rules keep the values faithful: + +1. **A `number` literal is never converted to a JavaScript number on the way to the codec.** Converting `9007199254740993` to a double rounds it, and converting `1.50` drops the trailing zero a `numeric` column keeps. The codec receives the text and decides. +2. **A `json` literal's body is parsed as JSON once, by the literal type.** Codecs receive the JSON value, not text they must parse themselves. + +## Writing a literal in PSL + +PSL has two ways to write a literal, and both produce the same literal. + +**Plain scalars** write `string`, `number`, and `boolean` literals, and need no tag. + +**Tagged literals** write any literal type, including ones with no plain scalar. A tagged literal is a tag followed by a string in any of PSL's three quote characters; its escapes and the canonical body (line endings normalised, the common indentation removed) are those of [ADR 129](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md). Tags are registered in `ControlMutationDefaults.defaultLiteralTagRegistry`, whose entry for a tag says which literal type it writes, and they follow ADR 129's prefixing rules. Each SQL target registers the `json` tag, with no prefixed alias. A tag that no pack in the contract's stack registers is `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`, and the message lists the registered tags. + +The `sql` tag is the one tag that does not write a literal type. Its body is a SQL expression, not a value of the column's type, so it lowers to a function default (`{ kind: 'function', expression }`) on any column, and no codec compatibility applies. + +The syntax tree keeps exactly what the author wrote. The formatter and the language server work from the tree; only the interpreter turns scalars and tagged literals into literals. + +## Codecs declare compatible literal types + +A codec descriptor declares the literal types its columns are compatible with. This is static metadata, next to `traits` and `targetTypes` on `CodecDescriptor`: it depends only on the codec id, never on a particular column's parameters. + +For each compatible literal type, the declaration may carry two functions: + +- **read**, from the literal's value to the codec's JSON form; +- **write**, from the codec's JSON form back to the literal's value, used when printing a schema. + +When the literal's value already is the codec's JSON form, the declaration names the literal type and carries no functions. That is the common case: + +| Codec | Compatible with | Functions | +|---|---|---| +| `pg/text@1` | `string` | none: the JSON form is the text | +| `pg/bytea@1` | `string` | none: the JSON form is base64 text | +| `pg/jsonb@1` | `json` | none: the JSON form is the JSON value | +| `pg/int8@1` | `number` | none: the JSON form is the digit text | +| `pg/numeric@1` | `number` | read removes leading zeros and the sign of zero, keeping trailing zeros | +| `pg/int4@1` | `number` | read turns whole-number text into a JSON number and refuses `1.5`, `NaN`, and `Infinity`; write does the reverse | + +The declaration's exact field names are settled when it is built. Its shape is below, where `readWholeNumber` stands for a shared helper that refuses text that is not a whole number and names the codec in its message: + +```ts +class PgJsonbDescriptor extends PostgresCodecDescriptor { + override readonly literalTypes = { json: {} } as const; +} + +class PgInt4Descriptor extends PostgresCodecDescriptor { + override readonly literalTypes = { + number: { + read: (text: string): JsonValue => readWholeNumber(this.codecId, text), + write: (json: JsonValue): string => String(json), + }, + } as const; +} +``` + +The codec instance keeps the checks that depend on column parameters. After a read function produces the JSON form, the interpreter passes it through the codec's existing `decodeJson`. A `vector(3)` column given a four-element `json` literal is refused there, with the vector codec's own message. + +## Reading a default + +Each step has one owner. + +1. **PSL parser.** Parses the `@default(...)` argument into a scalar or a tagged literal node, recording the source span. +2. **Interpreter.** Turns the node into a literal: a scalar becomes a `string`, `number`, or `boolean` literal; a tagged literal becomes a literal of the type its tag names. A `sql` tagged literal becomes a function default and stops here. +3. **Codec descriptor.** The interpreter looks up the column's codec descriptor. If the literal's type is not one it declares, the interpreter reports an error at the literal naming the codec and its compatible literal types. +4. **Read function.** The descriptor's read function, if any, turns the literal's value into the codec's JSON form. +5. **Codec instance.** `decodeJson` checks the value against the column. A value it refuses is reported at the literal with the codec's message. +6. **Contract.** The default is stored as `{ kind: 'literal', value }` in the codec's JSON form, like every literal default. + +Other text-based contract sources follow the same steps from their own syntax. The reader for the earlier Prisma schema language ([ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md)) turns that language's defaults into literals of a type and hands them to the same descriptors. The TypeScript contract builder is not a text source: `.default(value)` passes a value of the codec's own type, and TypeScript's types do the compatibility check. + +## Printing a default + +`contract infer` runs the steps in reverse for each introspected literal default: + +1. The target reads the database's default into the codec's JSON form. +2. The printer takes the first literal type the column's codec declares and applies its write function, if any, to get the literal's value. +3. A `string`, `number`, or `boolean` literal prints as a plain scalar. Any other literal type prints as a tagged literal with the tag that writes it. +4. When the codec declares no literal type, or its write function cannot express the value, the printer writes the database's expression as a `sql` tagged literal. Infer never drops a default. + +A printed schema therefore reads back to the same contract, because printing and reading pass through the same declaration. + +## Responsibilities + +| Layer | Owns | +|---|---| +| PSL parser | Scalars and tagged literal nodes, spans, canonicalisation of tagged bodies | +| Tag registry | Which literal type each tag writes; which tag writes raw SQL | +| Literal types | What each literal's value is: text, number text, boolean, JSON value | +| Interpreter and other text sources | Mapping their syntax to literals; reporting incompatibility at the literal | +| Codec descriptor | Compatible literal types; read and write functions where the JSON form differs | +| Codec instance | `decodeJson` checks that depend on column parameters | +| Contract | The JSON form, unchanged from [ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md) | + +## Consequences + +### Benefits + +- **Compatibility is checked before decoding.** An author who writes the wrong kind of value gets an error that names the codec and what it accepts, not whatever a failed decode happened to throw. +- **Codecs do not depend on PSL.** New tags, new fences, or a new text contract source change nothing in any codec. +- **Most codecs declare names only.** Conversion code exists only where a codec's JSON form differs from the literal's value, which in practice means number-like codecs. +- **Values are exact.** Numbers reach the codec as written, so big integers and decimals keep every digit. +- **JSON defaults are readable.** A document is written as JSON inside a fence, not as escaped text inside a string. +- **The contract format does not change.** A literal default is stored in the codec's JSON form, whichever way it was written. + +### Costs + +- **Codec authors learn one more concept.** A codec that should accept defaults written in a schema must declare its literal types. +- **Some values need a tag, and some existing schemas change.** A JSON default is written with the `json` tag, and a quoted JSON string or a quoted decimal is refused. Schemas that use either must be edited. +- **Every text contract source maps its own syntax.** The PSL interpreter and the earlier Prisma schema reader each turn their syntax into literals; neither holds per-type handling. + +## Settled details + +- **The first literal types** are `string`, `number`, `boolean`, and `json`. Byte strings, timestamps, and intervals are written as `string` literals holding the codec's text form. +- **Literal types are defined in the framework**, so a codec descriptor in any family can name them. +- **The declaration is optional.** A codec that declares no literal types accepts no literal defaults, and its columns take `sql` defaults only. Mongo codecs declare nothing, because no Mongo contract source reads defaults from text. +- **A JSON column is not compatible with a `string` literal.** `Jsonb @default("{}")` is an error that asks for `` json`{}` ``. The reader for the earlier Prisma schema language turns that language's quoted JSON into a `json` literal itself. +- **A decimal column is not compatible with a `string` literal.** `Decimal @default("1.50")` is an error, and the default is written `1.50`. +- **`NaN`, `Infinity`, and `-Infinity` are `number` literals**, because the PSL tokenizer reads them as numbers. Float and decimal codecs accept them; integer codecs refuse them. +- **JSON null is a value.** `` Json @default(json`null`) `` stores JSON null. +- **Enum columns are unchanged.** Their default is a bare member name, and enum codecs declare no literal types. +- **List columns keep PSL's list syntax.** Each element is a literal checked against the element codec's declaration, so `` Jsonb[] @default([json`{}`, json`[]`]) `` is valid and `Int[] @default([1, "x"])` is refused at its second element. +- **Diagnostics.** A literal whose type the codec does not declare is `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE`. A value the codec refuses is `PSL_INVALID_DEFAULT_LITERAL`, with the codec's message. A `json` body that is not valid JSON is `PSL_INVALID_JSON_LITERAL`. Each diagnostic points at the literal. + +## Alternatives considered + +### Codec methods that receive the parser's classification + +Codecs gain `encodePsl(value)` and `decodePsl(literal)`, where the literal is `{ kind: 'string' | 'number' | 'boolean', text }` produced by the PSL parser. This is close to the interface ADR 184 sketched. + +Rejected. The input to every codec becomes the PSL tokenizer's view of the source, which couples codecs to PSL. A JSON document can only arrive as a string with its quotes escaped. And there is still no compatibility check: a codec discovers that a literal is not for it by failing to decode it. + +### Codecs receive the raw argument text + +Whatever is written between `@default(` and `)` goes to the column codec as text, and the codec parses it. + +Rejected. The parser would need an unparsed argument form that exists for `@default` alone, and the formatter and language server would need to understand it. Every codec would reimplement PSL quoting and escaping. And a bare word such as `ACTIVE` could be an enum member or a string the codec reads, with nothing to tell them apart. + +### The literal type alone decides the JSON form + +Each literal type stores its value in one fixed JSON form, and codecs adapt their `decodeJson` to accept it. + +Rejected. `pg/int4@1`, `pg/int8@1`, and `pg/numeric@1` would all have to share one JSON form for numbers, which changes the stored form of existing contracts and gives up either the precision of big integers or the JSON number that small integers are stored as. + +### Try each JSON form until the codec accepts one + +A `number` literal is offered to the codec as a JSON number first, then as text, and the first form `decodeJson` accepts wins. + +Rejected. Compatibility is again discovered by failure, a value that two forms both decode is ambiguous, and the error the author sees comes from the last attempt rather than from the actual mismatch. + +### A separate registry of PSL converters keyed by codec id + +The PSL conversions live in a registry beside the codecs, as ADR 184's `PslLiteralCodec` interface suggested. + +Rejected.

Its four methods are `encode`, `decode`, `encodeJson` and `decodeJson`. Every codec has a **codec id** such as `pg/int4@1`. A **codec descriptor** holds the codec's static metadata, keyed by codec id: `traits`, `targetTypes`, a params schema, and the factory that makes codec instances. The descriptor is where this work adds a declaration. + +**Column defaults.** A column's default in the contract is one of two shapes. `{ kind: 'literal', value }` holds a value, stored in that column's codec JSON form. `{ kind: 'function', expression }` holds SQL text the database evaluates. Nothing in this work changes those two shapes. + +**Tagged literals.** PSL can write text that Prisma does not parse, as a **tag** followed by a string: `` sql`now()` ``. The tag says which pack owns the text. This already exists and is described in ADR 129. + +## 3. What you are building, in one paragraph + +Every literal column default gains a **literal type**: `string`, `boolean`, `int`, `float`, `bigint`, `decimal`, or `json`. Each literal type is defined once in the framework and produces exactly the value shape that the codecs naming it already accept in `decodeJson`. Each codec descriptor names the literal types its columns are compatible with, as a list of names carrying no functions. A contract source turns its own syntax into a literal of a type, the interpreter checks the type against the column's codec and reports a precise error when they do not match, and the literal type produces the value that goes through `decodeJson` into the contract. Printing a schema runs the same path backwards. No codec gains a method, and no per-type code remains in the interpreter or the printer. + +## 4. Read these first + +Everything listed is committed.

The design, in full + +### 6.1 Literal types live in the framework + +Add literal types to `packages/1-framework/1-core/framework-components`, alongside the codec surface in `src/shared/`, exported through `src/exports/codec.ts`. There are seven, and no others in this slice. + +| Literal type | The value it produces | Reading rules | Writing rules | +|---|---|---|---| +| `string` | The text | Escapes are already resolved by the source | Print as the source's string syntax | +| `boolean` | `true` or `false` | | | +| `int` | A JSON number, whole | Refuse text that is not a whole number, and refuse `NaN` and the infinities | Print the digits | +| `float` | A JSON number, or the text `NaN`, `Infinity`, or `-Infinity` | Accept a number, or one of those three words | Print a finite number plainly with no exponent; print the three special values as a quoted string | +| `bigint` | The digits as text | Refuse text that is not a whole number | Print the digits | +| `decimal` | Decimal text | Keep trailing zeros. Remove leading zeros and the sign of zero, so `007` reads as `7`, `-0` as `0`, and `-007.50` as `-7.50`. Accept `NaN`, `Infinity` and `-Infinity` | Print a finite decimal plainly with no exponent; print the three special values as a quoted string | +| `json` | A JSON value | Parse the body as JSON once | Print `JSON.stringify` of the value | + +The canonicalisation rules for `decimal` already exist on `main` in `packages/2-sql/2-authoring/contract-psl/src/number-literal-default.ts`, in `canonicalDecimalText`. Move that logic into the `decimal` literal type and delete that file, its export from `packages/2-sql/2-authoring/contract-psl/src/exports/resolution.ts`, and its test. + +A literal type must never convert a number through a JavaScript number except where the table says it produces a JSON number. `bigint` and `decimal` carry digits as text end to end. + +### 6.2 Codec descriptors name their literal types + +Add an optional member to `CodecDescriptor` in `packages/1-framework/1-core/framework-components/src/shared/codec-descriptor.ts`, and to `CodecDescriptorImpl`, naming the literal types that codec's columns are compatible with. It carries names only and no functions. A codec that names none accepts no literal defaults; its columns can still take a `sql` default. + +The complete inventory follows. Every codec id in the repository appears exactly once. Implement it exactly. + +**Postgres target, `packages/3-targets/3-targets/postgres/src/core/`:** + +| Codec ids | Literal type | +|---|---| +| `pg/text@1`, `pg/char@1`, `pg/varchar@1`, `pg/uuid@1`, `pg/inet@1`, `pg/bit@1`, `pg/varbit@1`, `pg/timetz@1`, `pg/interval@1`, `pg/bytea@1`, `pg/enum@1`, `pg/date-string@1`, `pg/time-string@1`, `pg/timestamp-string@1`, `pg/timestamptz-string@1`, `pg/date-temporal@1`, `pg/time-temporal@1`, `pg/timestamp-temporal@1`, `pg/timestamptz-temporal@1`, `pg/timestamptz-date@1` | `string` | +| `pg/int4@1`, `pg/int2@1`, `pg/int8number@1`, `pg/int@1` | `int` | +| `pg/float4@1`, `pg/float8@1`, `pg/float@1` | `float` | +| `pg/int8@1`, `pg/unboundedint@1` | `bigint` | +| `pg/numeric@1` | `decimal` | +| `pg/json@1`, `pg/jsonb@1` | `json` | +| `pg/bool@1` | `boolean` | +| `pg/text-array@1` | none. It is internal to list handling and no column authored in a schema uses it | + +`pg/enum@1` names `string` because its JSON form is the member's storage string. This does not change how enum defaults are written; see section 6.6. + +**SQLite target, `packages/3-targets/3-targets/sqlite/src/core/codecs.ts`:** `sqlite/text@1`, `sqlite/blob@1` and `sqlite/datetime@1` name `string`. `sqlite/integer@1` and `sqlite/bigintnumber@1` name `int`. `sqlite/real@1` names `float`. `sqlite/bigint@1` names `bigint`. `sqlite/json@1` names `json`. + +**SQL base codecs, `packages/2-sql/4-lanes/relational-core/src/ast/sql-codecs.ts`:** `sql/text@1`, `sql/char@1` and `sql/varchar@1` name `string`. `sql/int@1` names `int`. `sql/float@1` names `float`. + +**Extensions:** `pg/vector@1` and `arktype/json@1` name `json`. `pg/geometry@1` names `string`, because its JSON form is hexadecimal text. + +**Mongo:** `mongo/string@1`, `mongo/bool@1`, `mongo/date@1`, `mongo/double@1`, `mongo/int32@1`, `mongo/vector@1`, `mongo/array@1` and `mongo/document@1` name nothing and do not change. No Mongo contract source reads a default from text. + +`sqlite/real@1` and `sql/float@1` refuse `NaN` and the infinities inside `decodeJson` already. Leave that. The `float` literal type carries those values and the codec rejects them, which produces the right error on those targets. + +### 6.3 The PSL interpreter reads literals through literal types + +Files: `packages/2-sql/2-authoring/contract-psl/src/sql-attribute-specs.ts`, `psl-column-resolution.ts`. + +The `@default(...)` argument today has separate arms for a string, a number, a boolean, a list, a function call, an enum member, and, since slice A, a tagged literal. Replace the string, number and boolean arms with one arm that yields the written scalar and its syntax kind, keep the list arm wrapping it, and leave the function-call, enum-member and tagged-literal arms alone. + +Resolution order for a default that is a literal: + +1. A tagged literal takes the literal type its tag writes, from the tag registry. The `sql` tag is not a literal type and keeps slice A's behaviour of lowering to a raw SQL default. +2. A plain scalar takes its literal type from the column's codec declaration. **A string scalar takes `string` and a boolean scalar takes `boolean`, both unambiguous. A number scalar is the blocked decision in section 1: do not implement it until Will has answered.** +3. If the literal's type is not one the column's codec names, report `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE` at the literal, with a message naming the codec and the types it accepts, for example `Field "Account.meta": pg/int4@1 is not compatible with a json literal; it accepts int literals`. +4. Ask the literal type to read the written text. Text it refuses is `PSL_INVALID_DEFAULT_LITERAL` at the literal, with the reason. A `json` body that is not valid JSON is `PSL_INVALID_JSON_LITERAL`. +5. Pass the value to the column codec's `decodeJson`. A thrown error becomes `PSL_INVALID_DEFAULT_LITERAL` at the literal, carrying the codec's message. +6. Store the default as it is stored today. + +A missing codec in the lookup is an internal error, not a diagnostic: the lookup that resolved the column must carry its codec. + +### 6.4 The `json` tag + +Each SQL target registers a `json` tag in the registry slice A added, `ControlMutationDefaults.defaultLiteralTagRegistry`. Register it with no prefixed alias: `json` only, on Postgres and on SQLite. The registry entry says which literal type the tag writes. A tag no pack registers keeps slice A's diagnostic, `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`. + +### 6.5 The earlier Prisma version's schema reader + +Files under `packages/2-sql/2-authoring/contract-prisma7/src/`, principally `defaults.ts` and `target-binding.ts`, plus `packages/3-targets/3-targets/postgres/src/core/prisma7-binding.ts`. + +That reader has its own per-type handling for defaults, including a rule that `Int` and `BigInt` defaults must be whole numbers, and a path that parses quoted JSON text. Replace both with the same route as section 6.3: map the written syntax to a literal of a type, check it against the codec's declaration, read it with the literal type, pass it to `decodeJson`. Its diagnostics keep their existing code, `PSL.PRISMA7_UNKNOWN_DEFAULT`, with the reason from the literal type or the codec. + +Two behaviours of that reader stay exactly as they are: + +- A `Bytes` or `DateTime` default is carried as a raw SQL expression rather than a value, because verification cannot yet compare those as typed values. This is decision D11 in the project spec. +- Its diagnostic for a JSON default of `null`, `PSL.PRISMA7_JSON_NULL_DEFAULT_UNSUPPORTED`, stays and keeps firing. + +That language writes a JSON default as a quoted string, such as `@default("{\"a\":1}")`. The reader turns that quoted string into a `json` literal itself. Prisma 8's own PSL does not accept that form; see section 6.7. + +### 6.6 The printer + +Files: `packages/2-sql/9-family/src/core/psl-contract-infer/default-mapping.ts` and the Postgres printer under `packages/3-targets/3-targets/postgres/src/core/psl-infer/`. + +`contract infer` reads a live database and prints a schema. For a literal default it must now take the literal type the column's codec names, ask that type to write the stored value, and print the result: as a plain scalar where the literal type has one, otherwise as a tagged literal with the tag that writes it. When the codec names no literal type, or the literal type cannot write the value, keep whatever the printer does on `main` for a default it cannot express. Slice C changes that fallback; you do not. + +Delete the per-type formatter table in the Postgres printer, `PslDefaultValueFormat`, `pslDefaultValueFormat`, `formatPslValue`, `formatPslListLiteralValue` and the helpers they use, and the equivalent literal formatting in the family's `default-mapping.ts`. + +### 6.7 Behaviour that changes for people who already wrote schemas + +Three forms that work today become errors. Each needs an entry in the app-author upgrade instructions; section 9 says where. + +- A JSON column with a quoted JSON string, `Jsonb @default("{}")`. It becomes `` Jsonb @default(json`{}`) ``. +- A decimal column with a quoted decimal, `Decimal @default("1.50")`. It becomes `Decimal @default(1.50)`. +- Any other quoted value on a column whose codec names a non-`string` literal type. + +Two forms are unchanged and must stay working: an enum column's default is a bare member name, such as `@default(ACTIVE)`; and a list column keeps PSL's list syntax, `Int[] @default([1, 2])`, where each element is checked against the element codec's declaration, so `` Jsonb[] @default([json`{}`, json`[]`]) `` is valid and `Int[] @default([1, "x"])` is refused at its second element. + +`` Json @default(json`null`) `` is allowed and stores JSON null. + +### 6.8 What you must not change + +- The contract format. Every `contract.json` already in the repository must come out byte-identical. `pnpm fixtures:check` is the proof. +- The `Codec` interface. No codec gains a method in this slice. +- The TypeScript contract builder's `.default(value)`, which passes a value of the codec's own type and is checked by TypeScript. +- Anything about `dbgenerated`, which slice C removes. +- The DDL rendering half of ADR 184, which stays future work. + +## 7. Order of work + +1. Rewrite the slice specification (section 5). +2. Literal types in the framework, with their own tests (section 6.1). +3. The descriptor member and the full inventory of declarations, with a test per pack asserting every registered codec's declaration (section 6.2). +4. The `json` tag on both targets (section 6.4). +5.

Documentation and upgrade instructions (section 9). +10. Full gates and the pull request (sections 10 and 11). + +Steps 5 to 7 leave the repository in a state where numeric defaults do not yet work, so the branch is not ready to merge until step 8 lands. Do not open the pull request before then. + +## 8. What to reuse from the closed branch + +Branch `remove-dbgenerated-codec-psl-literals`. Take these by hand; ignore everything else on it, especially anything adding `encodePsl`, `decodePsl`, a `PslLiteral` type, or a `literal()` parser combinator. + +- **The end-to-end test** at `test/integration/test/cli-journeys/codec-psl-literal-defaults.e2e.test.ts`, which emits a schema using every literal kind, runs `db init`, verifies the database, and reads a row back through the client. Adapt its schema to the new syntax, in particular the JSON column. +- **The JSON round-trip case** in `test/integration/test/cli-journeys/infer-roundtrip-fidelity.e2e.test.ts`, which asserts that a `jsonb` default survives infer, emit and verify without a workaround. +- **The float fix** in `packages/3-targets/3-targets/postgres/src/core/codec-helpers.ts`: `pg/float4@1` and `pg/float8@1` carry `NaN` and the infinities as text in their JSON form and on the wire, and read them back as numbers. The `float` literal type depends on this. +- **The decimal canonicalisation behaviour** for `pg/numeric@1`, as test cases. The logic itself comes from `main` as section 6.1 says. +- **The Postgres printer's codec lookup**, `packages/3-targets/3-targets/postgres/src/core/psl-infer/infer-default-codec.ts`, which finds the codec that `contract emit` binds to a printed PSL type name. The printer needs a codec and this is how it gets one. Note the reason recorded there: several codecs share one database type, so the printed type name, not the database type, picks the codec. + +One trap from that branch: when the `@default` argument arms change, the language server's completion for `@default(` loses its `true` and `false` suggestions unless the new arm offers them. There is a test for it in `packages/1-framework/3-tooling/language-server`. + +## 9. Documentation to update in the same pull request + +- `docs/reference/error-reference.md`: add `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE`, `PSL_INVALID_DEFAULT_LITERAL` and `PSL_INVALID_JSON_LITERAL`, in the form its neighbours use, and update the earlier-version reader's message wording where it changed. +- `docs/reference/codec-authoring-guide.md`: a codec descriptor names its literal types; show one example. +- `packages/2-sql/2-authoring/contract-psl/README.md`: one paragraph on how a literal default is written and what the column's codec accepts. +- Upgrade instructions for the three broken forms in section 6.7, following the `record-upgrade-instructions` skill in `skills-contrib/record-upgrade-instructions/`.

The repository check for this is `pnpm check:upgrade-coverage --mode pr`. +- If ADR 253 has merged and your implementation diverges from it in any way, update the ADR in this pull request and say so in the description. + +## 10. How to work + +- Follow the Drive process: invoke the `drive-process` skill and run the slice with one implementer and one reviewer, resumed across dispatches. +- Tests before implementation, as `CLAUDE.md` requires. Every named test must fail before the change that makes it pass. +- Use `pnpm`, never `npm` or `npx`. Use the shell's Node; do not switch versions. +- Run slow commands through their `:agent` variants and read the log file each prints, per `.agents/rules/running-tests.mdc`. +- No `any`, no bare `as` casts in production code, no comments that restate the code, and test names that omit "should". The rules under `.agents/rules/` are not optional. +- Stage files explicitly and sign off every commit, per `.agents/rules/git-staging.mdc`. Do not push until the work is ready for review. + +## 11. Definition of done + +- `pnpm typecheck`, `pnpm test:packages`, `pnpm test:integration`, `pnpm test:e2e`, `pnpm lint`, `pnpm lint:deps`, `pnpm lint:docs` and `pnpm fixtures:check` all green, the last with no contract file changed. +- `pnpm lint:throws` and `pnpm check:upgrade-coverage --mode pr` green. Neither runs under `pnpm lint`, and continuous integration fails without them. +- `git grep -n "numberLiteralDefault\|PslDefaultValueFormat\|formatPslValue\|formatPslListLiteralValue" -- packages` returns nothing. +- A test per pack asserts that every codec it registers declares the literal types this brief's inventory gives it, so a codec added later without a declaration fails. +- The end-to-end test from section 8 passes against a real database, covering every literal type. +- One pull request against `main`, with a description that follows the `create-pr` skill in `skills-contrib/create-pr/`. This project has no Linear ticket, so omit the ticket prefix from the title and say so in the checklist. + +## 12. Stop and ask Will if + +- The blocked decision in section 1 is still unanswered when you reach step 8. +- A codec's JSON form turns out not to match the literal type this brief assigns it, so the declaration would need a conversion function after all. That would reopen the ADR's central claim. +- Making a codec declaration work would require changing what a `contract.json` stores. +- A contract source other than PSL and the earlier version's reader turns out to read literal defaults. +- The rewritten slice specification would need a design decision this brief does not give you.

There is no type-specific code in the interpreter, the printer, or the Prisma 7 source for numbers, JSON, or anything else. Concretely, after this slice: +Every literal column default has a literal type. A codec descriptor names the literal types its columns accept, as names only. A contract source turns its syntax into a literal of a type, the interpreter checks that type against the column's codec by membership, the codec's `decodeJson` converts the literal's value, and the printer runs the same path backwards. No codec gains a method. No per-type code remains in the interpreter or the printer. + +After this slice, all of the following are true: ```prisma -model T { - 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]) +model Account { + id Int @id + name String @default("anonymous") + small SmallInt @default(100) + count Int @default(100000) + balance BigInt @default(100000000000000099) + price Decimal @default(1.50) + ratio Float @default(NaN) + active Boolean @default(true) + meta Jsonb @default(json`{ "plan": "free", "seats": 1 }`) + scores Int[] @default([1, 2]) + docs Jsonb[] @default([json`{}`, json`[]`]) + embed pgvector.Vector(3) @default([0.1, 0.2, 0.3]) + expires DateTime @default(sql`now() + interval '3 days'`) } ``` -emits a contract in which `meta` holds the JSON object `{}`, `big` holds every digit, `price` holds `1.50` with its trailing zero, and `contract infer` prints each of them back in exactly that form. +Every one of those emits, migrates onto a dev database, verifies clean, reads back through the client with its decoded type, and `contract infer` prints them back in the same forms.

A number gets the smallest type that holds it. `42` is `i8` on every column; `100000000000000099` is `i64`; `1.50` is `decimal`; `NaN` is `float`. Reason: one syntax then names one type, the compatibility check is a lookup with no trial decoding, and a size error is reported as an incompatibility before anything is decoded. +2. **A codec names every type it accepts, and coercion between those types' value shapes is the codec's job, inside its existing `decodeJson`.** `pg/int8@1` names `i8` to `i64`, so its `decodeJson` accepts a JSON number as well as the digit text it stores. No new codec method; the declaration stays a list of names. Reason: the value shape a literal type produces is fixed by the type, and the codecs that store a different shape are the ones that know how to convert it. +3. **A vector default is a list, not a JSON document.** The brief gave `pg/vector@1` the `json` type because `json` was the only type producing an array. That matches on storage shape, which is the mistake `Jsonb @default("{}")` makes. Instead a declaration may name a list of element types, `{ list: [...] }`, and a PSL list on a non-list column writes a list literal. Serhii asked for `@default([1, 2, 3])` on a vector column and this gives it. This shape was proposed in the discussion and not objected to; it is open to review in the PR. + +## Corrections to the brief + +Verified against the code on 2026-09-18. Where the brief and this spec differ, this spec wins. + +- **`NaN`, `Infinity` and `-Infinity` print unquoted.** The PSL tokenizer reads them as number tokens (`tokenizer.ts`, `KEYWORD_NUMBERS`). The brief said to print them as a quoted string, which would read back as a `string` literal and be refused by every float codec. +- **`pg/enum@1` names no literal type.** Enum defaults are bare member names and never reach the codec (`enumDefaultArms` in `sql-attribute-specs.ts`), so naming `string` would be inert and would contradict ADR 253. The brief said `string`. +- **Mongo has seven codecs, not nine.** `mongo/array@1` and `mongo/document@1` do not exist. The seven (`mongo/objectId@1`, `mongo/string@1`, `mongo/double@1`, `mongo/int32@1`, `mongo/bool@1`, `mongo/date@1`, `mongo/vector@1`) name nothing, as the brief said. +- **`pg/float4@1` and `pg/float8@1` do no validation in `decodeJson` on `main`** (a blind cast), and their `encodeJson` turns `NaN` into JSON `null`. The closed branch's float fix is needed and is B2's job. +- **`sqlite/real@1`, `sql/float@1` and `pg/float@1` refuse non-finite values in `decodeJson`.** Confirmed. They therefore do not name `float`, so `Real @default(NaN)` on SQLite is an incompatibility diagnostic rather than a decode failure. The brief had them name `float`. +- **No allowlist exists for contributed diagnostic codes.** `ContributedPslDiagnosticCode` is the open type `` `PSL_${string}` ``; the new codes are declared as constants in `contract-psl` and need no framework edit. +- **`number-literal-default.ts` has no test file of its own.** Its behaviour is covered by `contract-psl/test/interpreter.number-defaults.test.ts` and `test/integration/test/number-defaults/psl-number-defaults.integration.test.ts`, both of which change in this slice. +- **The `@default` argument arms do not need merging.** `str()`, `numLiteral()` and `bool()` already yield the written scalar with its syntax kind (`string`, `{ text }`, `boolean`). Keeping them leaves the language server's `true`/`false` completion untouched. The brief said to replace them with one arm. +- **`build-contract.ts` re-encodes every literal default through `encodeJson`** (`encodeViaCodec`), so the interpreter stores the decoded value and the contract receives the canonical JSON form. The brief's step 6 ("store the default as it is stored today") is right; this records why the contract stays canonical. +- **`pg/text-array@1` is contract-free only** (`contract-free/columns.ts`); no PSL type binds it. Confirmed. +- **`CodecLookup.get(codecId)` cannot give a length-aware vector codec**; `control-stack.ts` builds the representative with empty params. The interpreter materialises the column's codec from the descriptor and the column's `typeParams` (B4). +- **The closed branch's float fix lives in `codecs.ts` and `codec-helpers.ts`**, not `codec-helpers.ts` alone. ## Design -### B1.

This PR edits it: the open question is closed with decisions 1 to 3 above; the literal-types table gains the numeric types by size; "Codecs declare compatible literal types" gains the list declaration and the coercion rule; the enum and non-finite float details in "Settled details" are corrected. The project spec's D9 and D10 gain a one-line amendment note pointing here, and the plan's slice C seam is updated (B6). ## Tests (written first; each named test must fail before its implementation lands) -Framework (`framework-components/test`): -- `PslLiteral` type test; `CodecImpl` subclass without the methods fails to compile (`test-d`). +Framework (`framework-components/test/literal-types.test.ts`): +- classification table: `0`, `-0`, `007` → `i8` value `7`; `127`/`128` boundary; `32767`/`32768`; `2147483647`/`2147483648`; `9007199254740993` → `i64` text; `9223372036854775807`/`9223372036854775808` → `i64`/`bigint`; `1.50` → `decimal` `"1.50"`; `-007.50` → `"-7.50"`; `-0.0` → `"0.0"`; `NaN`, `Infinity`, `-Infinity` → `float`. +- `json`: object, array, `null`, invalid text → `invalid-json` with a message. +- `isCompatible`: scalar in and out of a declaration; list against `{ list }`; list against scalars only; nested list refused. +- `writeLiteral`: each type round-trips its own value; number `1.5` against `i8..i32, decimal` → `1.5`; text `"42"` against `i8..` → `42`; `1e21`-magnitude number prints without exponent; non-finite prints unquoted; JSON value prints as a `json` tag, quote fence when the text has a backtick; `undefined` when nothing matches. +- `describeDeclarations` wording. + +Descriptor (`framework-components/test/codec.types.test-d.ts`): `literalTypes` is optional and typed as the declaration union. + +Per pack inventory test (B2), seven files, one per pack. + +Codec coercion (`postgres/test`, `sqlite/test`, `relational-core/test`, `pgvector/test`): for each codec in B2's coercion list, `decodeJson` accepts each named shape and refuses the rest; float4/float8 non-finite round-trip through `encodeJson`/`decodeJson` and `encode`/`decode`; `sqlite/integer@1` refuses `2**53 + 1`. -Per pack, a table test that for every codec the pack registers, `decodePsl(encodePsl(v))` equals `v` for at least one sample value per codec, and `decodePsl` of a wrong-kind literal throws with a message naming the codec. Packs: Postgres target, SQLite target, relational-core, pgvector, postgis, arktype-json, Mongo codec package. +Registry (`6-adapters/postgres/test/control-mutation-defaults.test.ts`, SQLite equivalent): tag registry holds `sql`, `pg.sql` (or `sqlite.sql`) and `json`;

missing `descriptorFor` → `InternalError`. +- `interpreter.defaults.tagged-literal.test.ts`: `json` tag cases incl. `json\`null\``, invalid JSON, `json` on an `Int` column → incompatible, `json` inside a list on `Jsonb[]`. +- language server `completion-provider.test.ts:766` stays green unchanged. -Printer (`9-family/test/psl-contract-infer/default-mapping.test.ts`, `postgres/test/psl-infer/print-psl/print-psl.defaults-and-types.test.ts`): -- every case above printed back to the same source text;

Report it. -- The Mongo codec package cannot depend on `PslLiteral` without a layering violation. Report; do not duplicate the type. +- A codec's `decodeJson` cannot accept a named shape without changing what `contract.json` stores. Report; do not add a per-codec branch in the interpreter. +- The Postgres printer cannot reach the emit-side type resolution and the hand map cannot be tested against it. Report the seam. +- A contract source other than PSL and the Prisma 7 reader reads literal defaults.

No new codec method; the declaration stays a list of names. Reason: the value shape a literal type produces is fixed by the type, and the codecs that store a different shape are the ones that know how to convert it. 3. **A vector default is a list, not a JSON document.** The brief gave `pg/vector@1` the `json` type because `json` was the only type producing an array. That matches on storage shape, which is the mistake `Jsonb @default("{}")` makes. Instead a declaration may name a list of element types, `{ list: [...] }`, and a PSL list on a non-list column writes a list literal. Serhii asked for `@default([1, 2, 3])` on a vector column and this gives it. This shape was proposed in the discussion and not objected to; it is open to review in the PR. +## Amendments made during the build + +These supersede the sections below where they differ. + +- **`writeLiteral` returns the complete literal source.** `text` is the whole written literal, including the tag and fence for `json` (`` json`{"a":1}` ``); `tag` is kept so a caller can tell a tagged literal apart. The printer prints `@default()`. (Dispatch 1.) +- **No quote-fence fallback when printing `json`.** A quote-fenced tagged literal resolves the full PSL string escapes, while a backtick fence resolves only `` \` `` and `\\`, so switching fences changes what a JSON body containing `\n` reads back as. The printer always uses the backtick fence and escapes backticks and backslashes. (Dispatch 1.) +- **A nested list is refused with reason `invalid-number`** and the message "A list literal cannot contain another list."; it maps to `PSL_INVALID_DEFAULT_LITERAL`. A list literal's `type.list` is the element types in first-seen order, deduplicated, so an empty list is compatible with every `{ list }` declaration. `describeDeclarations` joins scalar and list parts with " and ". `integerLiteralTypesUpTo('bigint')` is allowed. (Dispatch 1.) +- **`writeLiteral` writes a list literal itself** against a `{ list }` declaration (a scalar column such as `vector(3)`); the printer writes a list column's elements one by one against the element codec's scalar declarations. Two different paths. (Dispatch 1, for dispatch 5.) + ## Corrections to the brief Verified against the code on 2026-09-18. Where the brief and this spec differ, this spec wins. From e6ca2df462539ca24769df72a6adc3735da71310 Mon Sep 17 00:00:00 2001 From: willbot Date: Fri, 18 Sep 2026 15:10:30 +0200 Subject: [PATCH 10/81] fix(framework-components): review findings on the literal types The json tag always uses the backtick fence now, escaping backslashes and backticks, which is what resolveBacktickEscapes reverses; a quote fence resolves the full PSL string escapes and would change what a body containing \n reads back as. A refused list literal now carries the index of the element that was refused, so the interpreter can report at that element's span. The refusal shape is one interface, LiteralRefusal, with elementIndex required and undefined off the list path. The two kinds of default literal tag entry are told apart by one exported predicate rather than by each consumer knowing the discriminating key. Literal's scalar arm is ScalarLiteral. jsonDefaultLiteralTagEntry and LiteralTypeName are exported from the codec entrypoint only, beside the literal types, as spec B3 asks. The classification table pins the i16 and i32 minimums from both sides.

The seven packs are the Postgres target, the SQLite target, relational-core, pgvector, postgis, arktype-json and the Mongo adapter, which names nothing. The two target descriptor adapters forward literalTypes, so the sql/* codecs keep their declarations when a target re-registers them. ADR 253, slice B2 (inventory).

The exact integer codecs read a whole JSON number as well as digit text, and the number-valued ones read digit text, refusing anything past the safe integer range with a message naming the limit; sqlite/integer@1 gains that check, which it had for neither shape. pg/numeric@1 reads a JSON number. pg/float4@1 and pg/float8@1 carry NaN and the infinities as the text PostgreSQL reads and writes, in JSON and on the wire, instead of turning them into JSON null; the float codecs that refuse non-finite values still do. pg/vector@1 reads numeral text elements. numberLiteralDefault now takes the written text over the JSON number for a codec whose application value is text, so `Decimal @default(1.50)` keeps its trailing zero in the contract as it does today. That helper is deleted with the interpreter rewrite. ADR 253, slice B2 (coercion).

No per-type code and no per-codec branch is left in the interpreter: number-literal-default.ts, which trial-decoded a number two ways to see what stuck, is gone. Postgres and SQLite register the json tag, so a JSON default is written json`{ "plan": "free" }` rather than as a quoted string. A scalar column accepts a PSL list, which is how a pgvector column takes @default([0.1, 0.2, 0.3]), and a list element may be a tagged literal, so Jsonb[] @default([json`{}`]) parses. The codec's declaration decides whether either is accepted. Three diagnostics replace the decode crashes: a literal whose type the codec does not accept, a json body that is not JSON, and a literal the codec refuses to decode — the last carrying the codec's own message, so a vector default of the wrong length says so. A column bound to a value set keeps its member-name default, which is checked against the value set rather than read as a literal. The Prisma 7 reader keeps its own copy of the number-through-codec helper until it is rewritten. ADR 253, slice B3 and B4.

Each tag's completion and signature help carries the text of the tag it names — one tagged-literal arm per distinct documentation — instead of every registered tag's text run together. The list arm carries a readable label, so a syntax error reads `... | list of (string | number | boolean | sql`...` | json`...`)` rather than repeating the scalar alternatives and hanging `[]` off the last one; `list()` takes the label. Refusing a lowering tag as a list element has a test. The tag-body switch is exhaustive over the literal types. The fixture codec descriptors live in their own module.

The reader's own number handling — a whole-number check per scalar name, a trial decode through the codec two ways, and a JSON.parse for Json columns — is gone. Refusals are structured rather than pre-worded, so each source words its own diagnostic: PSL says the codec is not compatible with the literal, and the Prisma 7 reader says what the default holds and what the column accepts, keeping PSL.PRISMA7_UNKNOWN_DEFAULT. A number too large for its column is now refused with its literal type instead of decoding first. Unchanged: the sqlExpression form for Bytes and DateTime, and the JSON null default, which is still reported before the codec sees the literal. ADR 253, slice B5.

The per-PSL-type formatter table in the Postgres printer is gone, and with it the quoted decimals, quoted NaN and dropped JSON defaults. A decimal now prints unquoted and keeps its trailing zero, NaN and the infinities print as themselves, a json or jsonb default prints as a json tag, and a temporal default prints as the string its codec reads rather than as dbgenerated. The printer restates which codec emit binds to each printed PSL type name, because the authoring namespaces that own that binding sit in the adapter, above the target package. A test in the adapter fails if the two disagree, and a test in the target fails if the type map gains a printed name the table does not cover. A json or jsonb list default's elements are read as JSON documents, as a scalar column's already were, so a Jsonb[] default prints as a list of json tags rather than of quoted text.

The printer now passes the value through the column's codec before writing a literal and takes the raw-default fallback when it throws, so a schema infer prints is one emit reads. A new test prints a schema, parses it with the PSL parser and interprets it through the real codec descriptors, asserting every default comes back as the value the database reported — a string with quotes, backslashes, a newline and a non-ASCII character among them, which is also what keeps the printer's escaping and the parser's decoding in step. There is now one PSL string escaper, in the framework, beside writeLiteral. PRINTED_PSL_TYPE_NAMES covers the parameterized type table too.

A second test does the same for a pgvector column, whose codec declares a list of element types and checks the length. It found two places that materialised a column's codec without the column's typeParams, so a vector default could neither be re-encoded into the contract nor rendered into DDL: the contract builder and the Postgres DDL renderer now build the codec from its descriptor with the column's own params. The infer round-trip journey asserts a jsonb default prints as a json tag, a numeric keeps its trailing zero and a temporal default prints as the string its codec reads, then emits and verifies clean against the live database. A parity pair emits identical contracts from PSL and TypeScript for nine literal forms. A SQLite e2e case authored 0 and 1 as strings on integer columns, which the contract kept as text while the DDL now writes the number the column stores; it authors the numbers. ADR 253, slice B9.

The whole-number types are cut by width — `i8`, `i16`, `i32`, `i64`, then `bigint` for anything larger — and a number takes the smallest type that holds it, decided by comparing its digits as a `BigInt`, so no classification passes through a JavaScript number. -A PSL number scalar is written the same way everywhere, but under this design the literal type it produces depends on the column: `42` is an `int` literal on an `Int` column, a `bigint` literal on a `BigInt` column, and a `decimal` literal on a `Decimal` column. The column's codec decides, by what it declares, and that declaration is also the compatibility statement. +One syntax then names one literal type, the compatibility check is a lookup with no trial decoding, and a value too large for its column is reported as an incompatibility before anything is decoded: `Int @default(100000000000000099)` says `pg/int4@1 is not compatible with an i64 literal; it accepts i8, i16, i32 literals`. -That follows from cutting the literal types where the stored representations are cut, but it means one syntax does not name one literal type. Three answers are open: accept it as written here; give each numeric literal type a tag so a written literal always names its own type; or return to a single `number` literal type whose conversion each codec owns, at the cost described above. +This is why a codec names a *chain* of types rather than one: `pg/int4@1` names `i8` to `i32`, `pg/int8@1` names `i8` to `i64`.

Full design: ADR 254.* A literal default has a literal type, and the literal type says what the value is, independent of how PSL writes it. There are seven: `string`, `boolean`, `int`, `float`, `bigint`, `decimal`, and `json`. Each one is defined in the framework, and each produces the value shape the codecs that name it already accept in `decodeJson`, so `int` gives a whole JSON number, `bigint` gives the digits as text, `decimal` gives decimal text with its trailing zeros, and `json` gives a JSON value. PSL writes a literal of a given type in one of two ways. The plain PSL scalars write `string`, `boolean`, and the numeric literal types. A tag writes a literal of the type the tag names, as in `` @default(json`{ "a": 1 }`) ``; the tag registry entry says which literal type a tag writes, and each SQL target registers `json` with no prefixed alias. Both ways lower to the same literal. The syntax tree keeps what was written, for the formatter and the language server. The `sql` tag is different: it writes a raw SQL expression, not a value of the column's type. It lowers to a raw SQL default as D2 describes, and no codec check applies to it. -**Open, to discuss with the operator before implementation:** a plain number scalar names no literal type of its own, so `42` is an `int` literal on an `Int` column, a `bigint` literal on a `BigInt` column, and a `decimal` literal on a `Decimal` column, decided by what the column's codec declares. Whether to accept that, to give each numeric literal type its own tag, or to keep one `number` literal type that each codec converts, is not settled. The numeric literal types are not implemented until it is.

Nothing central computes which types convert into which. + +```prisma +model Account { + id Int @id @default(autoincrement()) + name String @default("anonymous") + small SmallInt @default(100) + balance BigInt @default(100000000000000099) + price Decimal @default(1.50) + ratio Float @default(NaN) + active Boolean @default(true) + meta Jsonb @default(json`{ "plan": "free", "seats": 1 }`) + scores Int[] @default([1, 2]) + status Status @default(ACTIVE) + token String @default(nanoid(8)) + expires DateTime @default(sql`(now() + '3 days'::interval)`) +} +``` + +Reading that model: `"anonymous"` is a value of `sql/string@1`; `100` is `sql/i8@1` and `100000000000000099` is `sql/i64@1`, classified by their digits; `1.50` is `sql/decimal@1`; `NaN` is `sql/float@1`; `` json`...` `` is `sql/json@1`, named by its tag; `[1, 2]` is a list whose elements are `sql/i8@1`; `ACTIVE` is a reference to a member of `Status`, not a literal; `8` inside `nanoid(8)` is `sql/i8@1` delivered to the function's size parameter; `` sql`...` `` is an expression in the database's language, which no data type reads. + +This ADR replaces the PSL half of [ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md). Its JSON half stands: the contract stores a literal default in the column codec's canonical JSON form. + +## Terms + +- A **data type** is a named kind of value with an id, a written form, and a canonical JSON representation. +- A **representation** is one encoding of a value: PSL literal text, the JSON form in `contract.json`, the wire form the driver exchanges, the in-memory JS value, a SQL expression. +- A **codec** transforms between representations of one data type, the type its column stores. Its descriptor is that type's static description: traits, the database types it binds to, its parameters, and the data types it accepts. +- A **receiver** is anything that takes a value: a column through its codec, a function parameter, and later an operator operand or a check-constraint slot. +- PSL has three **expression kinds**: a literal, a reference, and a call. + +## Data types + +A data type is a declaration: + +```ts +interface DataType { + readonly id: DataTypeId; + readonly written: WrittenForm; + read(text: string): ReadResult; + write(value: JsonValue): string; + readonly documentation: string; +} + +type WrittenForm = + | { readonly kind: 'number' } + | { readonly kind: 'string' } + | { readonly kind: 'boolean' } + | { readonly kind: 'tag'; readonly tag: string }; +``` + +- `id` follows the codec convention, `/@`: `sql/i32@1`, `sql/json@1`, `postgis/geometry@1`. A data type is referenced from the same places a codec is, descriptors, function signatures, diagnostics, and it is owned and versioned the same way. `DataTypeId` is a branded string. An id that no contributor registered is an assembly error. +- `written` says how a literal of the type is spelled: plain number syntax, a plain quoted string, `true`/`false`, or a tag followed by a string in any of PSL's quote styles, whose body is canonicalised per [ADR 129](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md). +- `read` turns literal text into the type's canonical JSON value, or refuses it with a reason. `write` turns a canonical value back into literal text. + +**Registration.** A pack contributes data types through the control stack, in the contribution that already carries its default functions: `ControlMutationDefaults.dataTypes`. Assembly merges every contributor's declarations and refuses two declarations of one id, two types claiming one tag, and two types claiming one plain syntax kind. The tag dictionary is not a second registry; it is the registered types whose written form is a tag. The `sql` tag is the one entry that names no data type: it is a lowering tag, whose body is an expression in the database's language, and it lowers to the contract's expression representation. It stays a lowering tag until a codec can convert that representation (the DDL half of ADR 184). + +**The list type.** `sql/list@1` is the type of a PSL list. Its values are JSON arrays; each element is read with its own type. A receiver that accepts lists names the element types it takes: `{ id: 'sql/list@1', of: ['sql/i8@1', 'sql/i16@1', ...] }`. A list is accepted when every element's type is in `of`. A nested list is refused. + +**Ownership.** The framework owns the mechanism: the declaration shape, the registry, assembly, dispatch, and a shared implementation of the number classifier that a family may adopt. It owns no types. The SQL family registers the numeric, string, boolean, JSON and list types, and both SQL targets contribute that set, as they contribute the `sql` tag. Mongo registers a number vocabulary that suits it. No type spans families, and nothing in the framework relates one family's types to another's. + +### The SQL family's types + +| Id | Written as | Canonical JSON value | +|---|---|---| +| `sql/string@1` | `"..."` | the text | +| `sql/boolean@1` | `true`, `false` | the boolean | +| `sql/i8@1`, `sql/i16@1`, `sql/i32@1` | a whole number within 8, 16, 32 bits | a JSON number | +| `sql/i64@1` | a whole number within 64 bits | digit text | +| `sql/bigint@1` | any larger whole number | digit text | +| `sql/decimal@1` | a number with a fraction | decimal text | +| `sql/float@1` | `NaN`, `Infinity`, `-Infinity` | the word | +| `sql/json@1` | `` json`...` `` | the parsed document | +| `sql/list@1` | `[a, b, ...]` | an array of the elements' values | + +Digit text drops leading zeros and the sign of zero and keeps trailing zeros: `007` reads as `7`, `-0` as `0`, `-007.50` as `-7.50`. `i64`, `bigint` and `decimal` carry digits as text because a JSON number rounds past 2^53 and drops a trailing zero. A written finite number is exact, so every number with a fraction is `decimal`; only the three IEEE words are `float`. `json` refuses a document containing a number that parses to a non-finite value. + +## Written forms + +The parser hands the interpreter a written literal with its syntax kind and span: + +```ts +type WrittenLiteral = + | { kind: 'number'; text: string; span: SourceSpan } + | { kind: 'string'; text: string; span: SourceSpan } + | { kind: 'boolean'; value: boolean; span: SourceSpan } + | { kind: 'tag'; tag: string; body: string; span: SourceSpan } + | { kind: 'list'; elements: readonly WrittenLiteral[]; span: SourceSpan }; +``` + +Mapping it to a data type: + +- A plain string maps to the registered type whose written form is `string`; a plain boolean to the type whose form is `boolean`. +- A plain number maps through the family's **classifier**, a function the family registers with its number types. The SQL family's rule is PostgreSQL's rule for literals: a whole number takes the narrowest of `i8`, `i16`, `i32`, `i64` that holds it, else `bigint`; a number with a fraction is `decimal`; the three words are `float`. The classifier exists so that a value is never rounded through a JavaScript number before its receiver sees it. +- A tag maps to the registered type whose tag it is. An unregistered tag is `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`, and the message lists the registered tags. A tag may name a type that also has a plain form, so `` i8`8` `` and `8` are the same value. +- A list maps to `sql/list@1`, its elements mapped by the same rules. + +The type's `read` then produces a **typed value**, `{ type: DataTypeId, value: JsonValue }`. Text the type refuses is `PSL_INVALID_DEFAULT_LITERAL`; a JSON body that does not parse is `PSL_INVALID_JSON_LITERAL`. Both point at the literal, or at the element inside a list. + +## Receivers + +A receiver declares `accepts: readonly DataTypeRef[]`, where a ref is an id or a list ref with its element ids. The declaration is the receiver's own statement of what it can convert into its type. It is made by the owner of the receiving type, because only the owner knows what its database or extension can take; this is how PostgreSQL's `pg_cast` works, declared per type by the type's owner. There is no central assignability rule. + +**A codec descriptor** declares `accepts` next to `traits` and `targetTypes`: + +```ts +class PgInt4Descriptor extends PostgresCodecDescriptor { + override readonly accepts = sqlIntegerTypesUpTo('sql/i32@1'); +} + +class PgVectorDescriptor extends PostgresCodecDescriptor { + override readonly accepts = [{ id: 'sql/list@1', of: [...sqlIntegerTypesUpTo('sql/i64@1'), 'sql/bigint@1', 'sql/decimal@1'] }]; +} +``` + +Conversion happens in the codec's existing `decodeJson`, which accepts the canonical value of every type in `accepts` as well as the codec's stored form. `pg/int8@1` accepts `i8` to `i64`, so its `decodeJson` reads a JSON number and digit text. `pg/numeric@1` accepts the integers, `decimal` and `float`, and reads a number as canonical decimal text. No codec gains a method. Checks that depend on parameters run in the codec instance built with the column's parameters: `vector(3)` refuses four elements, `numeric(10,2)` refuses a third decimal place. A limit of the stored representation is also the codec's to refuse: `sqlite/real@1` accepts `float` and refuses `NaN` in `decodeJson`, because SQLite cannot store it. A codec that declares nothing takes no literal value; its columns take `sql` only. + +**A function parameter** declares `accepts` the same way. `nanoid`'s size parameter accepts `sql/i8@1`; the function converts and range-checks its own arguments. This replaces the parser's argument kinds in function signatures, so a function argument and a column default are checked by one rule. + +**The column-default receiver** is the family: it accepts the column codec's `accepts` plus the `sql` lowering tag. + +## Expression kinds + +- **Literal.** Mapped to a typed value, checked against the receiver's `accepts`, converted by the receiver. A type the receiver does not accept is `PSL_DEFAULT_TYPE_INCOMPATIBLE`: `Field "Account.count": pg/int4@1 does not accept sql/i64@1; it accepts sql/i8@1, sql/i16@1, sql/i32@1`, with the element index when the value is inside a list. +- **Reference.** An identifier resolves through the symbol table to a declaration, and its value is the declaration's, of the declaration's type. An enum member resolves to the member declared in its `enum` block, and the check is scope: the member must belong to this column's enum. No classification and no `accepts` apply. +- **Call.** A registered function; each argument is an expression delivered to a parameter, which is a receiver. The call's result is what the function registry returns today, a storage default or an execution default. + +## Reading a default + +1. The parser yields a literal, a reference, or a call, with spans. +2. A reference resolves; a call dispatches to its function; a `sql` tag lowers. Any other literal maps to a typed value through the registry and the classifier. +3. The typed value's type is checked against the codec's `accepts`; for a list literal on a scalar column, each element's type against the list ref's `of`; for a list column, each element against the element codec. +4. The codec instance for the column's parameters runs `decodeJson`. A throw is reported at the literal with the codec's message. +5. The decoded value is stored. The contract builder re-encodes it through `encodeJson`, so the contract holds the codec's canonical JSON form. The contract's two default shapes, a JSON value and an expression, do not change. + +The reader for the earlier Prisma schema language ([ADR 253](ADR%20253%20-%20PSL%20red-root%20source%20ownership.md) is about its provenance; [ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md) makes it a contract source) runs the same steps from its own syntax: its quoted JSON on a JSON column is `sql/json@1`'s `read`, its numbers go through the classifier, and its `Bytes` and `DateTime` stay on the expression path until a codec converts that representation. The TypeScript builder is not a text source: it hands `encodeJson` a JS value that TypeScript has typed. + +## Printing + +`contract infer` inverts the mapping. For a stored literal value: classify the JSON value to a type by the same rules (a number or digit text through the classifier, a string as `string`, a boolean, an object as `json`, an array as `list` or `json` by what the codec accepts); confirm the codec accepts that type; call the type's `write`; run the text back through the codec's `decodeJson` to prove it reads; print it in the type's written form, plain or tagged. Any step that fails takes the raw-expression fallback, so infer never prints a schema emit cannot read. The printer obtains the column's codec from the type binding emit uses; where layering forbids that import, it restates the binding with a test that pins agreement. + +## Extending the set of types + +A pack that owns a type it wants writable in PSL registers one declaration: id, tag, `read`, `write`, documentation. Its codec lists the id in `accepts`, and its `decodeJson` reads the canonical value.

When a schema writes a default, something has to decide whether the written value suits the column. If the only information available is the characters the author typed, the codec has to try to read them and report failure by throwing. That makes compatibility a side effect of decoding, and the error the author sees is whatever the codec happened to throw. - -A literal type turns the question into a lookup. The literal says what kind of value it is. The codec says which kinds it accepts. A mismatch is reported before anything is decoded, with a message that names the codec and the literal types it accepts. - -### A codec should not depend on PSL - -Codecs live below every authoring surface. PSL is one surface; the schema language of earlier Prisma versions, read by the contract source in [ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md), is another. If a codec received PSL text, or the PSL parser's idea of what a token is, every codec would be coupled to PSL's quoting, escaping, and tokenizer rules. A change to PSL syntax would become a change to every codec. - -With literal types, each authoring surface maps its own syntax to literals, and codecs only ever receive a literal of a type they declared. PSL can gain new tags without any codec changing. - -### The literal types are cut where the stored representations are cut - -The contract stores a literal default in the column codec's JSON form ([ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md)). Codecs that hold numbers do not share one JSON form: - -| Column | Codec | Written | Stored in `contract.json` | -|---|---|---|---| -| `Int` | `pg/int4@1` | `42` | `42` | -| `BigInt` | `pg/int8@1` | `9007199254740993` | `"9007199254740993"` | -| `Decimal` | `pg/numeric@1` | `1.50` | `"1.50"` | - -A single `number` literal type would have to be converted per codec, which puts conversion code on every numeric codec. Instead the literal types are cut where those representations are cut, and the whole-number types are cut again by width — `i8`, `i16`, `i32`, `i64`, then `bigint` — so that a number too large for its column is a type the column does not accept rather than a value it fails to decode. The declaration is then a list of names, and the rules for whole numbers, decimal canonicalisation, and digit preservation are written once, in the literal type, rather than once per codec. - -## The literal types - -A literal type defines what its value is, how a written literal is read into that value, and how a stored value is written back. It is defined in the framework, so a codec descriptor in any family can name it. - -| Literal type | Written as | Value it produces | Named by | -|---|---|---|---| -| `string` | A string scalar | The text, with escapes resolved | Text, uuid, inet, bit and varbit, bytes as base64, geometry as hex, intervals, timestamps and dates as their text form | -| `boolean` | `true` / `false` | `true` or `false` | Boolean codecs | -| `i8` | A whole number in [-128, 127] | A JSON number | Every integer codec | -| `i16` | A whole number in [-32768, 32767] not already `i8` | A JSON number | `pg/int2@1` and wider | -| `i32` | A whole number in the signed 32-bit range not already smaller | A JSON number | `pg/int4@1`, `pg/int@1`, `sql/int@1` and wider | -| `i64` | A whole number in the signed 64-bit range not already smaller | The digits as text, because a JSON number rounds past 2^53 | `pg/int8@1`, `pg/int8number@1`, `sqlite/integer@1`, `sqlite/bigint@1`, `sqlite/bigintnumber@1` and wider | -| `bigint` | Any larger whole number | The digits as text | `pg/unboundedint@1`, and every codec over `numeric` or a float | -| `decimal` | A number with a fraction | Decimal text.

A number is never converted to a JavaScript number unless its literal type says so, because converting `9007199254740993` rounds it and converting `1.50` drops the trailing zero a `numeric` column keeps. And a `json` literal's body is parsed as JSON once, by the literal type, so codecs receive the JSON value rather than text they must parse. - -## Writing a literal in PSL - -PSL has two ways to write a literal, and both produce the same literal. - -**Plain scalars** write `string`, `boolean`, and the numeric literal types, and need no tag. - -**Tagged literals** write any literal type, including ones with no plain scalar. A tagged literal is a tag followed by a string in any of PSL's three quote characters; its escapes and the canonical body (line endings normalised, the common indentation removed) are those of [ADR 129](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md). Tags are registered in `ControlMutationDefaults.defaultLiteralTagRegistry`, whose entry for a tag says which literal type it writes, and they follow ADR 129's prefixing rules. Each SQL target registers the `json` tag, with no prefixed alias. A tag that no pack in the contract's stack registers is `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`, and the message lists the registered tags. - -The `sql` tag is the one tag that does not write a literal type. Its body is a SQL expression, not a value of the column's type, so it lowers to a function default (`{ kind: 'function', expression }`) on any column, and no codec compatibility applies. - -The syntax tree keeps exactly what the author wrote. The formatter and the language server work from the tree; only the interpreter turns scalars and tagged literals into literals. - -## Codecs declare compatible literal types - -A codec descriptor names the literal types its columns are compatible with. This is static metadata, next to `traits` and `targetTypes` on `CodecDescriptor`: it depends only on the codec id, never on a particular column's parameters. It carries no functions — a declaration is a list of names, and turning a named type's value into the codec's own form is work `decodeJson` already does. - -```ts -class PgJsonbDescriptor extends PostgresCodecDescriptor { - override readonly literalTypes = ['json'] as const; -} - -class PgInt4Descriptor extends PostgresCodecDescriptor { - override readonly literalTypes = integerLiteralTypesUpTo('i32'); -} - -class PgVectorDescriptor extends PostgresCodecDescriptor { - override readonly literalTypes = [ - { list: [...integerLiteralTypesUpTo('i64'), 'bigint', 'decimal'] }, - ] as const; -} -``` - -`integerLiteralTypesUpTo(name)` gives the chain from `i8` up to and including `name`, so a descriptor does not spell it out. - -The declaration is optional. A codec that names no literal type accepts no literal defaults, and its columns take raw SQL defaults only. - -**A codec converts between the shapes it names and its own stored form, inside its existing `decodeJson`.** The literal type fixes the shape of the value it produces, and a codec that stores a different shape is the one that knows how to convert: `pg/int8@1` stores digit text and names `i8` to `i64`, so its `decodeJson` accepts a whole JSON number as well as the text. No codec gains a method, and no contract source branches per codec. - -The codec instance keeps the checks that depend on column parameters. The interpreter builds the codec from the descriptor with the column's own `typeParams` and passes the literal type's value to `decodeJson`, so a `vector(3)` column given two elements is refused there, with the vector codec's own message. - -## Reading a default - -Each step has one owner. - -1. **PSL parser.** Parses the `@default(...)` argument into a scalar or a tagged literal node, recording the source span. -2. **Interpreter.** Turns the node into a written literal, independent of the source language: the text of a string, the digits of a number as written, a boolean, the body of a tag, or a list of those. A `sql` tagged literal becomes a function default and stops here. -3. **Literal types.** Reading the written literal gives its type and its value together: a number's type comes from its own size and precision, a tag's from the type its tag names. Text no literal type reads — a number with an exponent, a `json` body that is not a JSON document — is refused here. -4. **Compatibility.** If the literal's type is not one the column's codec declares, the interpreter reports an error naming the codec, the literal's type, and the types the codec accepts. Nothing has been decoded. -5. **Codec instance.** `decodeJson` converts the literal type's value into the codec's own form and checks it against the column. A value it refuses is reported with the codec's message. -6. **Contract.** The default is stored as `{ kind: 'literal', value }` in the codec's JSON form, like every literal default. - -Other text-based contract sources follow the same steps from their own syntax. The reader for the earlier Prisma schema language ([ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md)) turns that language's defaults into literals of a type and checks them against the same declarations. The TypeScript contract builder is not a text source: `.default(value)` passes a value of the codec's own type, and TypeScript's types do the compatibility check. - -## Printing a default - -`contract infer` runs the steps in reverse for each introspected literal default: - -1. The target reads the database's default into the codec's JSON form. -2. The printer takes the literal type the column's codec declares and asks it to write that value. -3. A literal type with a plain scalar prints as that scalar. Any other prints as a tagged literal with the tag that writes it. A `json` body always uses the backtick fence, escaping backslashes and backticks: a quote-fenced tagged literal resolves the full PSL string escapes, so switching fences would change what a body containing `\n` reads back as. -4. **The printer passes what it wrote back through the column's codec's `decodeJson`** before printing it. A literal type says what a value is written as, not that the codec accepts every value of that shape — the temporal codecs name `string` but refuse `infinity`, which PostgreSQL stores and reports verbatim. -5. When the codec names no literal type, the literal type cannot write the value, or the codec does not read it back, the printer writes the database's expression as a raw SQL default instead. Infer never drops a default. - -A printed schema therefore reads back to the same contract, because printing and reading pass through the same literal type. - -The printer needs the codec bound to each PSL type name it prints. That binding lives in the adapter's authoring type namespaces, which sit above the target package the printer is in, so the target restates it for the type names it prints and a test in the adapter fails if the two disagree — the same shape as any other restated invariant, with the check that keeps it honest. - -## Responsibilities - -| Layer | Owns | -|---|---| -| PSL parser | Scalars and tagged literal nodes, spans, canonicalisation of tagged bodies | -| Tag registry | Which literal type each tag writes; which tag writes raw SQL | -| Literal types | The value each literal holds, reading a written literal into it, and writing a stored value back | -| Interpreter and other text sources | Mapping their syntax to written literals; wording the refusals in their own diagnostics | -| Codec descriptor | The names of the compatible literal types | -| Codec instance | `decodeJson`: converting each named type's value shape into the codec's own form, and the checks that depend on column parameters | -| Contract | The JSON form, unchanged from [ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md) | - -## How a plain scalar picks its literal type - -**Settled: from the number itself, never from the column.** - -A written number's literal type comes from its own size and precision. `42` is an `i8` on every column, `100000000000000099` an `i64`, `1.50` a `decimal`, `NaN` a `float`. The whole-number types are cut by width — `i8`, `i16`, `i32`, `i64`, then `bigint` for anything larger — and a number takes the smallest type that holds it, decided by comparing its digits as a `BigInt`, so no classification passes through a JavaScript number. - -One syntax then names one literal type, the compatibility check is a lookup with no trial decoding, and a value too large for its column is reported as an incompatibility before anything is decoded: `Int @default(100000000000000099)` says `pg/int4@1 is not compatible with an i64 literal; it accepts i8, i16, i32 literals`. - -This is why a codec names a *chain* of types rather than one: `pg/int4@1` names `i8` to `i32`, `pg/int8@1` names `i8` to `i64`. The cost is that a codec whose stored shape differs from a named type's shape converts between them, which the section above makes its job. - -## Settled details - -- **The declaration is optional**, and Mongo codecs name nothing, because no Mongo contract source reads defaults from text. -- **A JSON column is not compatible with a `string` literal.** `Jsonb @default("{}")` is an error that asks for `` json`{}` ``. The reader for the earlier Prisma schema language turns that language's quoted JSON into a `json` literal itself. -- **A decimal column is not compatible with a `string` literal.** `Decimal @default("1.50")` is an error, and the default is written `1.50`. -- **`NaN`, `Infinity`, and `-Infinity` are `float` literals**, because the PSL tokenizer reads them as numbers, and they are written and printed bare — a quoted `"NaN"` is a `string` literal, which no numeric codec accepts. The integer literal types refuse them. -- **`sqlite/real@1`, `sql/float@1` and `pg/float@1` do not name `float`**, because their `decodeJson` refuses non-finite values. `Real @default(NaN)` on SQLite is therefore an incompatibility reported at the attribute, not a decode failure at emit. -- **JSON null is a value.** `` Json @default(json`null`) `` stores JSON null. -- **Enum columns are unchanged.** Their default is a bare member name, and enum codecs name no literal types. -- **List columns keep PSL's list syntax.** Each element is a literal checked against the element codec's declaration, so `` Jsonb[] @default([json`{}`, json`[]`]) `` is valid and `Int[] @default([1, "x"])` is refused, naming the second element. -- **A list literal on a scalar column needs a `{ list }` declaration.** `` Jsonb @default([1, 2]) `` is an incompatibility, because `pg/jsonb@1` names only `json`; the JSON array is written `` json`[1, 2]` ``. A vector column accepts one because `pg/vector@1` names a list of element types. -- **A diagnostic inside a list names the failing element in its message** (`Field "N.scores" at element 2: ...`) and is reported at the `@default(...)` attribute, because the attribute-spec layer carries no span for a string, number or boolean argument. -- **Diagnostics.** A literal whose type the codec does not declare is `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE`. Text a literal type cannot read, and a value a codec refuses, are `PSL_INVALID_DEFAULT_LITERAL` with the reason. A `json` body that is not valid JSON is `PSL_INVALID_JSON_LITERAL`. Each diagnostic points at the literal. - -## Alternatives considered - -### Codec methods that receive the parser's classification - -Codecs gain `encodePsl(value)` and `decodePsl(literal)`, where the literal is `{ kind: 'string' | 'number' | 'boolean', text }` produced by the PSL parser. This is close to the interface ADR 184 sketched. - -Rejected. The input to every codec becomes the PSL tokenizer's view of the source, which couples codecs to PSL. A JSON document can only arrive as a string with its quotes escaped. And there is still no compatibility check: a codec discovers that a literal is not for it by failing to decode it. - -### One `number` literal type, converted per codec - -A single `number` literal type carries the digits as text, and each numeric codec declares a read function to its own JSON form and a write function back. - -Rejected. Every numeric codec carries conversion code that duplicates what its `decodeJson` already does, and the rules for whole numbers, decimal canonicalisation, and digit preservation are written once per codec instead of once per literal type. - -### Codecs receive the raw argument text - -Whatever is written between `@default(` and `)` goes to the column codec as text, and the codec parses it. - -Rejected. The parser would need an unparsed argument form that exists for `@default` alone, and the formatter and language server would need to understand it. Every codec would reimplement PSL quoting and escaping. And a bare word such as `ACTIVE` could be an enum member or a string the codec reads, with nothing to tell them apart. - -### Try each JSON form until the codec accepts one - -A number literal is offered to the codec as a JSON number first, then as text, and the first form `decodeJson` accepts wins. - -Rejected. Compatibility is again discovered by failure, a value that two forms both decode is ambiguous, and the error the author sees comes from the last attempt rather than from the actual mismatch. - -### A separate registry of PSL converters keyed by codec id - -The PSL conversions live in a registry beside the codecs, as ADR 184's `PslLiteralCodec` interface suggested. - -Rejected. The codec descriptor is already the codec-id-keyed home for a codec's static metadata. A second registry would hold the same kind of information in a second place and could drift from the codecs it describes. - -## Related - -- [ADR 184 — Codec-owned value serialization](ADR%20184%20-%20Codec-owned%20value%20serialization.md): codecs own the JSON form of values.

Its id is `owner/name`: `pg/int8`, `pg/json`, `sqlite/integer`, `postgis/geometry`. The id has no version, because a type's identity does not change; what changes over time is a representation of it, which is a codec, and codecs are versioned (`pg/int8@1`). The two forms differ visibly so that one string never names both. + +A data type has a **canonical form**: the one JSON shape `contract.json` stores for a value of the type. `pg/int8` stores digit text; `pg/int4` stores a JSON number; `pg/json` stores the document. + +A data type declares its **casts**: for each other type whose values it takes, a pure function from that type's canonical form to its own. + +```ts +const pgInt8 = dataType('pg/int8', { + casts: { + [pgInt2.id]: (n) => String(n), + [pgInt4.id]: (n) => String(n), + }, +}); +``` + +A cast exists only where a conversion exists. Where two kinds of column hold the same kind of value they share one type, and where a written value already has the column's type nothing is cast. + +Casts are declared by the type that receives, never by the source, so there is at most one cast for any pair and the owner of a type is the only one who decides what it takes. That ownership rule is the one PostgreSQL uses for its own cast table, and the rule is all we borrow: these casts are between our data types, applied in the framework before a value is stored or sent, and they model nothing about what the database can convert. Nothing central computes convertibility, because only a type's owner knows what its database or extension can take. + +There is no list data type. A list literal is several values, each cast on its own; a list column is a column of one type with `many` set, checked element by element. A type whose single value holds several elements, such as a vector, declares a cast whose source is a list of other types, and each element is checked against that set. + +**Types are the target's.** No type spans targets. Postgres registers `pg/int2`, `pg/int4`, `pg/int8`, `pg/numeric`, `pg/float4`, `pg/float8`, `pg/text`, `pg/bool`, `pg/json` and the rest; SQLite registers `sqlite/integer`, `sqlite/real`, `sqlite/text`, `sqlite/json` and the rest. The SQL family registers no types. It exports implementations targets share, such as the digit classifier and the JSON parse and print, and each target declares its own types with those. + +## Codecs + +A codec transforms between representations of one data type: the canonical form in the contract, the wire form the driver exchanges, and the in-memory JS value. Its descriptor names the type: + +```ts +class PgInt8NumberDescriptor extends PostgresCodecDescriptor { + override readonly codecId = 'pg/int8number@1'; + override readonly dataType = pgInt8.id; +} +``` + +Several codecs may serve one type. `pg/int8@1` and `pg/int8number@1` both transform `pg/int8`, differing in the in-memory value they produce, a `bigint` and a `number`; both store digit text, and `pg/int8number@1` refuses text past 2^53 as a limit of its own representation. `pg/json@1` and `pg/jsonb@1` both transform `pg/json`, differing in the database type they bind to. `decodeJson` takes the canonical form and nothing else; `encodeJson` produces it. A codec has no method for PSL and never sees PSL text. + +Checks that depend on a column's parameters run in the codec instance built with those parameters, on the canonical form: `vector(3)` refuses four elements, `numeric(10,2)` refuses a third decimal place, an enum codec refuses a member it was not declared with. A limit of the stored representation is also the codec's to refuse: `sqlite/real@1` refuses `NaN`, because SQLite cannot store it, with its own message. Whether a SQLite boolean is stored as the integer `1` is likewise the boolean type's codec's business, not the written value's. + +## How PSL writes a value + +The pack that owns a data type contributes PSL support for it, keyed by the type's id, in its authoring contribution: + +```ts +authoring: { + dataTypes: { + [pgJson.id]: { + written: { tag: 'json' }, + parse: (body) => JSON.parse(body), // tag body → canonical form; refuses what it cannot read + print: (value) => JSON.stringify(value), + documentation: 'A JSON document.', + }, + [pgText.id]: { written: { plain: 'string' }, parse, print }, + [pgBool.id]: { written: { plain: 'boolean' }, parse, print }, + ...postgresNumberEntries, // written: { plain: 'number' }, one classifier, several types + }, +} +``` + +There are two ways a value is written. + +**With a tag.** A tag is a qualified name followed by a string in any of PSL's quote styles, whose body is canonicalised as [ADR 129](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md) describes. The entry's `parse` turns the body into the type's canonical form and `print` does the reverse. A target may register an unprefixed tag; every other pack prefixes: `json` is registered by each SQL target for its own JSON type, `postgis.geometry` by the postgis extension. + +**Plainly.** Three pieces of syntax the interpreter reads without a tag: a quoted string, `true`/`false`, and a number. Each target says which of its types they are. A number is the one plain kind that yields several types, so the target's number entry carries a **classifier** that picks the type from the digits. Postgres's rule is PostgreSQL's own rule for literals: a whole number takes the narrowest of `pg/int2`, `pg/int4`, `pg/int8` that holds it; anything else, a larger whole number, a number with a fraction, or `NaN`, `Infinity`, `-Infinity`, is `pg/numeric`. SQLite's rule: a whole number within 64 bits is `sqlite/integer`, a number with a fraction is `sqlite/real`, a larger number has no SQLite type and is refused. Digit text has no leading zeros and no negative zero, and keeps trailing zeros: `007` is `7`, `-007.50` is `-7.50`. A type may be writable both ways; `` int2`8` `` and `8` would be the same value if a target registered such a tag. + +The float types cast from the numeric one: `pg/float8` casts from `pg/int2`, `pg/int4`, `pg/int8` and `pg/numeric`, and the cast from `pg/numeric` turns the three words into non-finite numbers. That is why `Float @default(1.5)` and `Float @default(NaN)` both work without a float literal of their own. + +One tag names no data type. `sql` takes an expression in the database's language, which nothing in the framework reads, and stores it in the contract's expression form on any column. It is registered in the same place as the others, as the one **lowering** entry. + +The language server takes tag completion and documentation from the same entries. So does `contract infer`, and so does the reader for the earlier Prisma schema language, which maps its own syntax onto the same plain kinds and, for quoted JSON on a JSON column, the `json` entry's `parse`. + +## Three kinds of expression + +PSL has three kinds of expression, and each has one rule. + +- **A literal** is written plainly or with a tag. The interpreter finds the entry, calls `parse`, and has a value of a known type. The receiving type must be that type or cast from it: for a column, the codec's type; for a function argument, the parameter's declared type; inside a list, per element. No cast is `PSL_DEFAULT_TYPE_INCOMPATIBLE`: `Field "Account.count": pg/int4 has no cast from pg/int8; it casts from pg/int2`. Text the entry cannot parse is `PSL_INVALID_DEFAULT_LITERAL`; a JSON body that does not parse is `PSL_INVALID_JSON_LITERAL`; a tag nobody registered is `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`. Every one points at the written value. +- **A reference** is an identifier. It resolves through the symbol table to a declaration, and its value is that declaration's, of the declaration's type. An enum member resolves to the member declared in its `enum` block, and the only check is scope: the member must belong to this column's enum. No parsing and no cast. +- **A call** names a registered function. Each argument is an expression delivered to a parameter, and a parameter names a data type, so an argument is admitted by the same rule as a default. Function registries are per target, so `nanoid`'s size parameter is `pg/int4` on Postgres and `sqlite/integer` on SQLite, with one shared implementation. The call produces what the function registry defines, a storage default or a client-side generator. + +Reading a default is then: + +1. The parser yields a literal, a reference, or a call, with source spans. +2. A reference resolves; a call dispatches; a `sql` tag lowers. Any other literal is parsed to a value of a known type. +3. If the value's type is not the column's, the column's type is looked up for a cast from it. None is a diagnostic at the value. +4. The canonical form, cast or not, is validated by the codec instance for the column's parameters; a refusal is a diagnostic at the value with the codec's message. +5. The canonical form is stored. The contract's two default forms, a value and an expression, are the same as before this decision. + +The TypeScript builder is not a text surface: `.default(value)` hands the codec a JS value that TypeScript has typed, and `encodeJson` produces the canonical form. + +## Assembly + +The control stack assembles every pack's data types, codec descriptors and authoring entries into one stack and checks them against each other. It fails with a structured error, naming the contributor and the dangling id, when: + +1. a codec names a data type that is not registered; +2. an authoring entry, or a source in some type's casts, names a data type that is not registered; +3. two entries claim one tag, or one plain kind; +4. a type that appears as a source in some cast has no authoring entry, because a cast from a type nobody can write can never be exercised. + +The reverse of the last is not required: a stored type such as `pg/int8` need not be writable directly if values reach it through casts, although on Postgres it is. Assembly is the right level for these checks because they span packs: `pgvector/vector` casting from `pg/numeric` is valid only when the Postgres target that owns `pg/numeric` is in the stack. Within a pack, references are by constant rather than by string, so a misspelt id fails to compile and an unregistered one fails assembly. + +## Printing + +`contract infer` inverts the mapping. For a stored value, the printer classifies the canonical form with the same rules a written value uses: digit text or a number through the target's classifier, a document as the JSON type, text as the text type, a boolean, an array element by element. It confirms the column's type is that type or casts from it, prints with the entry's `print`, and runs the text back through parse and cast to prove it returns the stored value. Anything that fails takes the raw-expression fallback, so infer never prints a schema that emit cannot read. + +## Extending the set of types + +A pack that owns a type it wants writable in PSL registers three things together, referencing one constant: the data type with its casts, its codec naming the type, and its authoring entry with the tag, `parse`, `print` and documentation. Nothing in the interpreter, the printer, the language server or the readers changes. A geometry type with a WKT tag is the model case: + +```prisma +model Place { + id Int @id + location Geometry @default(postgis.geometry`POINT(1 2)`) +} +``` + +## Consequences + +- A written value is never rounded before its receiving type sees it. +- A JSON default is a document, written and printed as one. +- Defaults and function arguments are admitted by one rule. +- Two codecs of one type share the contract form. Where they did not before, contracts change form once and are re-emitted. +- Registering a data type without PSL support for it, or a codec without a data type, is an assembly error, not a runtime surprise. + +## Alternatives considered + +- **Codec methods that receive PSL text** (`encodePsl`/`decodePsl`, the sketch in [ADR 184](ADR%20184%20-%20Codec-owned%20value%20serialization.md)). Every codec becomes coupled to PSL's tokenizer and escaping, and there is no check before a decode fails. +- **A central rule for which types convert into which.** Databases and extensions define their own types and their own conversions; the framework cannot know them. A type's own casts are the only honest declaration. +- **Conversion inside the codec**, the codec listing what it takes and converting in `decodeJson`. Two codecs of one type repeat the same fact and the same conversion, and `decodeJson` ends up accepting shapes the codec never writes. +- **A family-level vocabulary of written types** (`sql/i8`, `sql/json`, …) that every target's types cast from. It invents types no database has, and most of its casts would be identities between a value and itself. +- **One `number` type converted per receiver.** Big numbers round, and every numeric receiver carries the same conversion. +- **The column decides a written number's type.** One syntax would not name one type, and a size error would surface inside a codec instead of as a missing cast. +- **A closed set of types in the framework.** An extension cannot add one, and the framework owns a vocabulary that belongs to targets. +- **A list data type.** A list is several values of one type; the shape belongs to the column or to the receiving type's cast. +- **Enum members as string values.** A member name is a reference to a declaration, resolved in scope like a field name. +- **Casts declared by the source type, or by both sides.** Two declarations for one pair, with no rule for which wins. +- **A vector type casting from the JSON type.** It matches on storage shape; a vector is several numbers. + +## Not decided here + +Whether temporal, bytes and interval types get tags of their own and stop casting from the text type; whether a codec will one day convert the `sql` representation (the DDL half of ADR 184); the Mongo target's number vocabulary. + +## Related + +- [ADR 184 — Codec-owned value serialization](ADR%20184%20-%20Codec-owned%20value%20serialization.md): the canonical form now belongs to the data type; the PSL half is replaced by this decision. +- [ADR 129 — Tagged literals](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md): the tag syntax and canonical body; a tag is how PSL writes a data type, and `sql` is the one lowering tag. +- [ADR 252 — An earlier Prisma version's schema is a contract source](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md): a second text source mapped onto the same types. diff --git a/docs/architecture docs/adrs/ADR 254 - Data types for values in PSL.md b/docs/architecture docs/adrs/ADR 254 - Data types for values in PSL.md deleted file mode 100644 index 4c820986f095..000000000000 --- a/docs/architecture docs/adrs/ADR 254 - Data types for values in PSL.md +++ /dev/null @@ -1,182 +0,0 @@ -# ADR 254 — Data types for values in PSL - -Status: **Accepted** - -## Decision - -PSL values have **data types**.

Its descriptor is that type's static description: traits, the database types it binds to, its parameters, and the data types it accepts. -- A **receiver** is anything that takes a value: a column through its codec, a function parameter, and later an operator operand or a check-constraint slot. -- PSL has three **expression kinds**: a literal, a reference, and a call. - -## Data types - -A data type is a declaration: - -```ts -interface DataType { - readonly id: DataTypeId; - readonly written: WrittenForm; - read(text: string): ReadResult; - write(value: JsonValue): string; - readonly documentation: string; -} - -type WrittenForm = - | { readonly kind: 'number' } - | { readonly kind: 'string' } - | { readonly kind: 'boolean' } - | { readonly kind: 'tag'; readonly tag: string }; -``` - -- `id` follows the codec convention, `/@`: `sql/i32@1`, `sql/json@1`, `postgis/geometry@1`. A data type is referenced from the same places a codec is, descriptors, function signatures, diagnostics, and it is owned and versioned the same way. `DataTypeId` is a branded string. An id that no contributor registered is an assembly error. -- `written` says how a literal of the type is spelled: plain number syntax, a plain quoted string, `true`/`false`, or a tag followed by a string in any of PSL's quote styles, whose body is canonicalised per [ADR 129](ADR%20129%20-%20Template-Tagged%20Literals%20for%20Extensions.md). -- `read` turns literal text into the type's canonical JSON value, or refuses it with a reason. `write` turns a canonical value back into literal text. - -**Registration.** A pack contributes data types through the control stack, in the contribution that already carries its default functions: `ControlMutationDefaults.dataTypes`. Assembly merges every contributor's declarations and refuses two declarations of one id, two types claiming one tag, and two types claiming one plain syntax kind. The tag dictionary is not a second registry; it is the registered types whose written form is a tag. The `sql` tag is the one entry that names no data type: it is a lowering tag, whose body is an expression in the database's language, and it lowers to the contract's expression representation. It stays a lowering tag until a codec can convert that representation (the DDL half of ADR 184). - -**The list type.** `sql/list@1` is the type of a PSL list. Its values are JSON arrays; each element is read with its own type. A receiver that accepts lists names the element types it takes: `{ id: 'sql/list@1', of: ['sql/i8@1', 'sql/i16@1', ...] }`. A list is accepted when every element's type is in `of`. A nested list is refused. - -**Ownership.** The framework owns the mechanism: the declaration shape, the registry, assembly, dispatch, and a shared implementation of the number classifier that a family may adopt. It owns no types. The SQL family registers the numeric, string, boolean, JSON and list types, and both SQL targets contribute that set, as they contribute the `sql` tag. Mongo registers a number vocabulary that suits it. No type spans families, and nothing in the framework relates one family's types to another's. - -### The SQL family's types - -| Id | Written as | Canonical JSON value | -|---|---|---| -| `sql/string@1` | `"..."` | the text | -| `sql/boolean@1` | `true`, `false` | the boolean | -| `sql/i8@1`, `sql/i16@1`, `sql/i32@1` | a whole number within 8, 16, 32 bits | a JSON number | -| `sql/i64@1` | a whole number within 64 bits | digit text | -| `sql/bigint@1` | any larger whole number | digit text | -| `sql/decimal@1` | a number with a fraction | decimal text | -| `sql/float@1` | `NaN`, `Infinity`, `-Infinity` | the word | -| `sql/json@1` | `` json`...` `` | the parsed document | -| `sql/list@1` | `[a, b, ...]` | an array of the elements' values | - -Digit text drops leading zeros and the sign of zero and keeps trailing zeros: `007` reads as `7`, `-0` as `0`, `-007.50` as `-7.50`. `i64`, `bigint` and `decimal` carry digits as text because a JSON number rounds past 2^53 and drops a trailing zero. A written finite number is exact, so every number with a fraction is `decimal`; only the three IEEE words are `float`. `json` refuses a document containing a number that parses to a non-finite value. - -## Written forms - -The parser hands the interpreter a written literal with its syntax kind and span: - -```ts -type WrittenLiteral = - | { kind: 'number'; text: string; span: SourceSpan } - | { kind: 'string'; text: string; span: SourceSpan } - | { kind: 'boolean'; value: boolean; span: SourceSpan } - | { kind: 'tag'; tag: string; body: string; span: SourceSpan } - | { kind: 'list'; elements: readonly WrittenLiteral[]; span: SourceSpan }; -``` - -Mapping it to a data type: - -- A plain string maps to the registered type whose written form is `string`; a plain boolean to the type whose form is `boolean`. -- A plain number maps through the family's **classifier**, a function the family registers with its number types. The SQL family's rule is PostgreSQL's rule for literals: a whole number takes the narrowest of `i8`, `i16`, `i32`, `i64` that holds it, else `bigint`; a number with a fraction is `decimal`; the three words are `float`. The classifier exists so that a value is never rounded through a JavaScript number before its receiver sees it. -- A tag maps to the registered type whose tag it is. An unregistered tag is `PSL_UNKNOWN_DEFAULT_LITERAL_TAG`, and the message lists the registered tags. A tag may name a type that also has a plain form, so `` i8`8` `` and `8` are the same value. -- A list maps to `sql/list@1`, its elements mapped by the same rules. - -The type's `read` then produces a **typed value**, `{ type: DataTypeId, value: JsonValue }`. Text the type refuses is `PSL_INVALID_DEFAULT_LITERAL`; a JSON body that does not parse is `PSL_INVALID_JSON_LITERAL`. Both point at the literal, or at the element inside a list. - -## Receivers - -A receiver declares `accepts: readonly DataTypeRef[]`, where a ref is an id or a list ref with its element ids. The declaration is the receiver's own statement of what it can convert into its type. It is made by the owner of the receiving type, because only the owner knows what its database or extension can take; this is how PostgreSQL's `pg_cast` works, declared per type by the type's owner. There is no central assignability rule. - -**A codec descriptor** declares `accepts` next to `traits` and `targetTypes`: - -```ts -class PgInt4Descriptor extends PostgresCodecDescriptor { - override readonly accepts = sqlIntegerTypesUpTo('sql/i32@1'); -} - -class PgVectorDescriptor extends PostgresCodecDescriptor { - override readonly accepts = [{ id: 'sql/list@1', of: [...sqlIntegerTypesUpTo('sql/i64@1'), 'sql/bigint@1', 'sql/decimal@1'] }]; -} -``` - -Conversion happens in the codec's existing `decodeJson`, which accepts the canonical value of every type in `accepts` as well as the codec's stored form. `pg/int8@1` accepts `i8` to `i64`, so its `decodeJson` reads a JSON number and digit text. `pg/numeric@1` accepts the integers, `decimal` and `float`, and reads a number as canonical decimal text. No codec gains a method. Checks that depend on parameters run in the codec instance built with the column's parameters: `vector(3)` refuses four elements, `numeric(10,2)` refuses a third decimal place. A limit of the stored representation is also the codec's to refuse: `sqlite/real@1` accepts `float` and refuses `NaN` in `decodeJson`, because SQLite cannot store it. A codec that declares nothing takes no literal value; its columns take `sql` only. - -**A function parameter** declares `accepts` the same way. `nanoid`'s size parameter accepts `sql/i8@1`; the function converts and range-checks its own arguments. This replaces the parser's argument kinds in function signatures, so a function argument and a column default are checked by one rule. - -**The column-default receiver** is the family: it accepts the column codec's `accepts` plus the `sql` lowering tag. - -## Expression kinds - -- **Literal.** Mapped to a typed value, checked against the receiver's `accepts`, converted by the receiver. A type the receiver does not accept is `PSL_DEFAULT_TYPE_INCOMPATIBLE`: `Field "Account.count": pg/int4@1 does not accept sql/i64@1; it accepts sql/i8@1, sql/i16@1, sql/i32@1`, with the element index when the value is inside a list. -- **Reference.** An identifier resolves through the symbol table to a declaration, and its value is the declaration's, of the declaration's type. An enum member resolves to the member declared in its `enum` block, and the check is scope: the member must belong to this column's enum. No classification and no `accepts` apply. -- **Call.** A registered function; each argument is an expression delivered to a parameter, which is a receiver. The call's result is what the function registry returns today, a storage default or an execution default. - -## Reading a default - -1. The parser yields a literal, a reference, or a call, with spans. -2. A reference resolves; a call dispatches to its function; a `sql` tag lowers. Any other literal maps to a typed value through the registry and the classifier. -3. The typed value's type is checked against the codec's `accepts`; for a list literal on a scalar column, each element's type against the list ref's `of`; for a list column, each element against the element codec. -4. The codec instance for the column's parameters runs `decodeJson`. A throw is reported at the literal with the codec's message. -5. The decoded value is stored. The contract builder re-encodes it through `encodeJson`, so the contract holds the codec's canonical JSON form. The contract's two default shapes, a JSON value and an expression, do not change. - -The reader for the earlier Prisma schema language ([ADR 253](ADR%20253%20-%20PSL%20red-root%20source%20ownership.md) is about its provenance; [ADR 252](ADR%20252%20-%20An%20earlier%20Prisma%20version's%20schema%20is%20a%20contract%20source.md) makes it a contract source) runs the same steps from its own syntax: its quoted JSON on a JSON column is `sql/json@1`'s `read`, its numbers go through the classifier, and its `Bytes` and `DateTime` stay on the expression path until a codec converts that representation. The TypeScript builder is not a text source: it hands `encodeJson` a JS value that TypeScript has typed. - -## Printing - -`contract infer` inverts the mapping. For a stored literal value: classify the JSON value to a type by the same rules (a number or digit text through the classifier, a string as `string`, a boolean, an object as `json`, an array as `list` or `json` by what the codec accepts); confirm the codec accepts that type; call the type's `write`; run the text back through the codec's `decodeJson` to prove it reads; print it in the type's written form, plain or tagged. Any step that fails takes the raw-expression fallback, so infer never prints a schema emit cannot read. The printer obtains the column's codec from the type binding emit uses; where layering forbids that import, it restates the binding with a test that pins agreement. - -## Extending the set of types - -A pack that owns a type it wants writable in PSL registers one declaration: id, tag, `read`, `write`, documentation.

Two codecs of the same database type, `pg/int8@1` and `pg/int8number@1`, could not say so, and stored the same value in two different contract forms. -Giving written values data types, and letting each receiving type say what it casts from, answers all three with one rule. +Giving written values and columns data types, and letting each type declare what it casts from, answers all of these with one entity. ## Data types -A data type is a named kind of value that a target or an extension registers. Its id is `owner/name`: `pg/int8`, `pg/json`, `sqlite/integer`, `postgis/geometry`. The id has no version, because a type's identity does not change; what changes over time is a representation of it, which is a codec, and codecs are versioned (`pg/int8@1`). The two forms differ visibly so that one string never names both. - -A data type has a **canonical form**: the one JSON shape `contract.json` stores for a value of the type. `pg/int8` stores digit text; `pg/int4` stores a JSON number; `pg/json` stores the document. - -A data type declares its **casts**: for each other type whose values it takes, a pure function from that type's canonical form to its own. +A data type is registered by the target or extension that owns the database type: ```ts const pgInt8 = dataType('pg/int8', { + ddl: { name: 'int8', aliases: ['bigint'] }, casts: { [pgInt2.id]: (n) => String(n), [pgInt4.id]: (n) => String(n), }, }); + +const pgNumeric = dataType('pg/numeric', { + ddl: { name: 'numeric', aliases: ['decimal'], render: ({ precision, scale }) => ... }, + params: numericParamsSchema, // precision, scale + casts: { ... }, +}); ``` -A cast exists only where a conversion exists. Where two kinds of column hold the same kind of value they share one type, and where a written value already has the column's type nothing is cast. +- **Id.** `owner/name`, with no version: `pg/int8`, `sqlite/integer`, `postgis/geometry`. A type's identity does not change; what changes over time is a representation of it, which is a codec, and codecs are versioned (`pg/int8@1`). The two forms differ visibly so that one string never names both. +- **DDL name and aliases.** The name the migration planner renders and the names introspection may report for the same type: `numeric` and `decimal`, `character varying` and `varchar`. `json` and `jsonb` are two database types and therefore two data types. +- **Parameters and rendering.** A parameterised type declares its parameter schema and how its DDL name is rendered with them: `numeric(10,2)`, `vector(1536)`, `timestamp(3)`. Parameters do not make a new type; `numeric(10,2)` holds values of `pg/numeric` under a constraint. +- **Canonical form.** The one JSON shape `contract.json` stores for a value of the type. `pg/int8` stores digit text; `pg/int4` a JSON number; `pg/jsonb` the document. Every codec of the type stores and reads exactly this form. +- **Casts.** For each other type whose values this type takes, a pure function from that type's canonical form to this one's. A cast may convert (`pg/int2` to `pg/int8` turns a number into digit text; `pg/numeric` to `pg/float8` turns text and the words `NaN`, `Infinity`, `-Infinity` into numbers) or may return the value unchanged (`pg/json` to `pg/jsonb`); either way the declaration is the point: this type takes those values. Casts are declared by the type that receives, never by the source, so there is at most one cast for any pair and the owner of a type is the only one who decides what it takes. That ownership rule is the one PostgreSQL uses for its own cast table, and the rule is all we borrow: these casts are between our data types, applied in the framework before a value is stored or sent, and they model nothing about what the database can convert. Nothing central computes convertibility, because only a type's owner knows what its database or extension can take. There is no list data type. A list literal is several values, each cast on its own; a list column is a column of one type with `many` set, checked element by element. A type whose single value holds several elements, such as a vector, declares a cast whose source is a list of other types, and each element is checked against that set. -**Types are the target's.** No type spans targets. Postgres registers `pg/int2`, `pg/int4`, `pg/int8`, `pg/numeric`, `pg/float4`, `pg/float8`, `pg/text`, `pg/bool`, `pg/json` and the rest; SQLite registers `sqlite/integer`, `sqlite/real`, `sqlite/text`, `sqlite/json` and the rest.

(Dispatch 5.) - -- **A column's codec is materialised with the column's `typeParams` wherever a default passes through it**: the interpreter (B4), the contract builder's `encodeJson` re-encode, and the Postgres DDL renderer. The last two used the param-less representative and so could not encode or render a `vector(3)` default. (Dispatch 6.) -- **The e2e journey's raw SQL default is written in the form Postgres reports** (`(now() + '3 days'::interval)`), because strict verification compares raw expressions; the Outcome snippet is updated. Pre-existing raw-SQL behaviour, not a literal-type matter. (Dispatch 6.) -- **The TypeScript builder cannot express a `BigInt` default beyond 2^53 or a non-finite `Float` default**, so those two forms are covered by the e2e journey and not by the parity pair. Recorded as a follow-up in the plan's open items. (Dispatch 6.) +## Decisions that scope this slice -- **A contract that stores digit text for a `sqlite/integer@1` default now renders `DEFAULT 0` rather than `DEFAULT '0'`**, because the SQLite DDL renderer decodes through the codec before rendering and the codec now reads digit text as a number. Authoring a string on an integer column was never legitimate; the upgrade instructions record the change. (Dispatch 6 review.) +Agreed with Will and Serhii on 2026-09-21. -## Corrections to the brief - -Verified against the code on 2026-09-18. Where the brief and this spec differ, this spec wins. - -- **`NaN`, `Infinity` and `-Infinity` print unquoted.** The PSL tokenizer reads them as number tokens (`tokenizer.ts`, `KEYWORD_NUMBERS`). The brief said to print them as a quoted string, which would read back as a `string` literal and be refused by every float codec. -- **`pg/enum@1` names no literal type.** Enum defaults are bare member names and never reach the codec (`enumDefaultArms` in `sql-attribute-specs.ts`), so naming `string` would be inert and would contradict ADR 254. The brief said `string`. -- **Mongo has seven codecs, not nine.** `mongo/array@1` and `mongo/document@1` do not exist. The seven (`mongo/objectId@1`, `mongo/string@1`, `mongo/double@1`, `mongo/int32@1`, `mongo/bool@1`, `mongo/date@1`, `mongo/vector@1`) name nothing, as the brief said. -- **`pg/float4@1` and `pg/float8@1` do no validation in `decodeJson` on `main`** (a blind cast), and their `encodeJson` turns `NaN` into JSON `null`. The closed branch's float fix is needed and is B2's job. -- **`sqlite/real@1`, `sql/float@1` and `pg/float@1` refuse non-finite values in `decodeJson`.** Confirmed. They therefore do not name `float`, so `Real @default(NaN)` on SQLite is an incompatibility diagnostic rather than a decode failure. The brief had them name `float`. -- **No allowlist exists for contributed diagnostic codes.** `ContributedPslDiagnosticCode` is the open type `` `PSL_${string}` ``; the new codes are declared as constants in `contract-psl` and need no framework edit. -- **`number-literal-default.ts` has no test file of its own.** Its behaviour is covered by `contract-psl/test/interpreter.number-defaults.test.ts` and `test/integration/test/number-defaults/psl-number-defaults.integration.test.ts`, both of which change in this slice. -- **The `@default` argument arms do not need merging.** `str()`, `numLiteral()` and `bool()` already yield the written scalar with its syntax kind (`string`, `{ text }`, `boolean`). Keeping them leaves the language server's `true`/`false` completion untouched. The brief said to replace them with one arm. -- **`build-contract.ts` re-encodes every literal default through `encodeJson`** (`encodeViaCodec`), so the interpreter stores the decoded value and the contract receives the canonical JSON form. The brief's step 6 ("store the default as it is stored today") is right; this records why the contract stays canonical. -- **`pg/text-array@1` is contract-free only** (`contract-free/columns.ts`); no PSL type binds it. Confirmed. -- **`CodecLookup.get(codecId)` cannot give a length-aware vector codec**; `control-stack.ts` builds the representative with empty params. The interpreter materialises the column's codec from the descriptor and the column's `typeParams` (B4). -- **The closed branch's float fix lives in `codecs.ts` and `codec-helpers.ts`**, not `codec-helpers.ts` alone. +1. **A data type is the database type made first-class, per target.** No family-level types. On Postgres the types coincide with the database's: `pg/int2`, `pg/int4`, `pg/int8`, `pg/numeric`, `pg/json`, `pg/jsonb`, and so on. On SQLite, whose storage classes are shared by several logical types, the target declares its own: `sqlite/integer` and `sqlite/bigint` are distinct types although both are `INTEGER`; `sqlite/text`, `sqlite/datetime` and `sqlite/json` are distinct although all are `TEXT`. The rule is: the target declares the types it distinguishes, and each codec names exactly one of them. +2. **Codecs of one type share its canonical contract form.** `pg/int8number@1` joins `pg/int8@1` on digit text; `sqlite/bigintnumber@1` joins `sqlite/bigint@1` on digit text. Existing contracts with such columns change form once; we are in the RC and that is an emit and a sign. +3. **Strict.** A codec that names no registered data type is an assembly error. In-repo extensions (pgvector, postgis, arktype-json) are migrated in this slice; external authors get an upgrade instruction. +4. **A cast that returns the value unchanged is a valid declaration.** `pg/jsonb` casts from `pg/json` unchanged; it states that jsonb takes json values. +5. **Not in this slice** (an independent project implements them): DDL name, aliases, parameters and their rendering moving from codec descriptors onto data types; `nativeType` derived and dropped from the contract; type constructors naming a type and a codec; function parameters typed by a data type through the attribute spec; temporal and bytes tags; the Mongo target's types beyond a name per codec. ## Design -### B1.

A scalar literal's type must appear by name. A list literal needs a `{ list }` declaration whose element names include every element's type. -- `describeDeclarations(declarations): string` for messages: `i8, i16, i32 literals`, `a list of i8, ... literals`, or `no literal defaults`. -- `writeLiteral(value: JsonValue, declarations): { text: string; tag?: LiteralTypeName } | undefined`. Tries the declarations in order; the first type whose `write` accepts the value wins. Used by the printer (B6). +`listCast` is how a type whose single value holds several elements (vector) takes a PSL list: each element's type must be in `of`, and `cast` receives the elements' canonical forms. There is no list data type. -The types, their value shapes, and the rules: +`CodecDescriptor` gains `readonly dataType: DataTypeId`, required, abstract on `CodecDescriptorImpl`; `literalTypes` is removed.

The control stack assembles them into a `DataTypeLookup` (`get(id)`, `has(id)`) beside `CodecLookup`, refusing two declarations of one id, and enforces at assembly, with a structured error naming the contributor and the dangling id: -Classification is by the number's text alone using `BigInt` comparison; no literal type converts through a JavaScript number except `i8`, `i16` and `i32`, whose values are exact. The tokenizer admits no exponent and no leading `+`, so the number regexes are `^-?\d+$` and `^-?\d+\.\d+$` plus the three words. +1. every codec's `dataType` is registered; +2. every `authoring.dataTypes` key and every cast source (scalar and `listCast.of`) is registered; +3. no two authoring entries claim one tag or one plain kind; +4. every cast source has an authoring entry (a type nobody can write cannot be cast from). -`write` for a numeric type accepts a JSON number or numeric text, classifies it, and prints it only when the classification is that type. A finite JSON number prints plainly with no exponent (the existing `plainNumeral` logic from the Postgres printer moves here). So a stored `pg/int8@1` text `"42"` prints `42` through `i8`, and a stored `pg/float8@1` number `1.5` prints `1.5` through `decimal`. +References inside a pack are by constant (`pgInt8.id`), never by string literal. -Provide `integerLiteralTypesUpTo(name)` returning the chain `['i8', ...]` up to and including `name`, so descriptors do not spell the chain out. +### B2.

Each codec's `decodeJson` accepts the value shape of every type it names, in addition to its own JSON form, and refuses the rest with its existing error code: - -- `pg/int8@1`, `sqlite/bigint@1`, `pg/unboundedint@1`: a whole JSON number as well as digit text. -- `pg/int8number@1`, `sqlite/bigintnumber@1`, `sqlite/integer@1`: digit text as well as a number; text past `Number.MAX_SAFE_INTEGER` is refused with a message naming the codec's limit. `sqlite/integer@1` gains that check for numbers too, since it has none today. -- `pg/numeric@1`: a JSON number, stored as its canonical decimal text. -- `pg/float4@1`, `pg/float8@1`: digit or decimal text, and the three non-finite words. Their JSON form for a non-finite value becomes the word as text, and `encode`/`decode` carry it on the wire the same way (the closed branch's float fix, `pgFloatEncode`, `pgFloatEncodeJson`, `pgFloatDecodeJson`, without its `encodePsl`/`decodePsl`). -- `pg/float@1`, `sql/float@1`, `sqlite/real@1`: digit or decimal text; non-finite still refused. -- `pg/vector@1`: elements may be digit or decimal text. -- Every other codec is unchanged. - -Per pack, one test asserts the full inventory: it walks the pack's registered descriptors and compares each `codecId` to `literalTypes` against a table, and fails on a codec missing from the table.

The `json` tag +For the plain `number` syntax one entry per target carries the **classifier**: `classify(text): { type: DataTypeId; value: JsonValue } | undefined`.

Assembly merges every contributor's map (invariant 3 above). The language server reads tag completion and documentation from these entries; the interpreter, the printer and the Prisma 7 reader read `parse`, `print` and the classifier. -`ControlDefaultLiteralTagEntry` in `mutation-default-types.ts` becomes a union: the existing lowering entry (`usage`, `documentation`, `lower`) for `sql`, and a literal-type entry (`usage`, `documentation`, `literalType: LiteralTypeName`) for `json`.

A codec whose database type is not in this table is a halt condition. -1. A tagged literal: look up the registry entry. A lowering entry lowers as today (`sql`). A literal-type entry yields `{ kind: 'json', text: body }` as the written literal (the only literal-type tag today; the code is generic over `literalType`). -2. A string, number, boolean or list value yields the matching `WrittenLiteral`; a list element that is a tagged literal is handled as in step 1 within the list. -3. `readLiteral`. `invalid-json` is `PSL_INVALID_JSON_LITERAL`; any other refusal is `PSL_INVALID_DEFAULT_LITERAL`.

The canonical form is stored as the default's literal value. `build-contract.ts` no longer re-encodes a PSL default (it still encodes a TypeScript `.default(value)` through `encodeJson`); `AuthoredColumnDefaultLiteralValue` loses its `bigint` arm if nothing else needs it. -### B7. Behaviour that changes for existing schemas +`PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE` is renamed `PSL_DEFAULT_TYPE_INCOMPATIBLE`. The Prisma 7 reader (`contract-prisma7/src/defaults.ts`) calls the same core with its own syntax mapped onto the plain kinds and the `json` entry; its diagnostic code and the Bytes/DateTime expression path are unchanged. -- `Jsonb @default("{}")` becomes `` Jsonb @default(json`{}`) ``. -- `Decimal @default("1.50")` becomes `Decimal @default(1.50)`. -- `Float @default("NaN")` becomes `Float @default(NaN)`. -- Any quoted value on a column whose codec does not name `string`. +### B7. The printer -Unchanged: enum member defaults; list syntax on list columns; `` Json @default(json`null`) `` stores JSON null. +`packages/2-sql/9-family/src/core/psl-contract-infer/default-mapping.ts`, `packages/3-targets/3-targets/postgres/src/core/psl-infer/`. For a stored literal: classify the canonical form with the target's rules (digit text or a number through the classifier, the three words → the numeric type, a document → the JSON type, text → the text type, a boolean, an array element by element); confirm the column's type is that type or casts from it; print with the source entry's `print`; run the text back through parse and cast and confirm it equals the stored value; otherwise the raw-expression fallback. `infer-default-codec.ts` resolves a printed type name to a codec descriptor as on the branch, and reads the type from it. ### B8. Docs and upgrade instructions -- `docs/reference/error-reference.md`: `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE`, `PSL_INVALID_DEFAULT_LITERAL`, `PSL_INVALID_JSON_LITERAL`, in the neighbours' form; the Prisma 7 message wording where it changed. -- `docs/reference/codec-authoring-guide.md`: a section on `literalTypes` with one scalar and one list example, and the coercion rule. -- `contract-psl/README.md`: one paragraph replacing the word "literals" in the `@default` list. -- `upgrade-instructions/pending/literal-types-column-defaults/app/instructions.md` (the three forms in B7, with detection on `*.prisma`) and `.../extension/instructions.md` (descriptors name `literalTypes`; `decodeJson` accepts every named shape), per the `record-upgrade-instructions` skill. - -### B9. Reused from the closed branch - -By hand, from `origin/remove-dbgenerated-codec-psl-literals`: the e2e test `test/integration/test/cli-journeys/codec-psl-literal-defaults.e2e.test.ts`, with its schema rewritten to the Outcome forms and a vector column added; the jsonb case in `infer-roundtrip-fidelity.e2e.test.ts`; the float fix (B2); the decimal canonicalisation cases as tests. Nothing that adds `encodePsl`, `decodePsl`, `PslLiteral`, or the `literal()` combinator. - -### B10. ADR 254 amendment - -ADR 254 is on the unmerged branch of PR 30334 and merged into this branch. This PR edits it: the open question is closed with decisions 1 to 3 above; the literal-types table gains the numeric types by size; "Codecs declare compatible literal types" gains the list declaration and the coercion rule; the enum and non-finite float details in "Settled details" are corrected. The project spec's D9 and D10 gain a one-line amendment note pointing here, and the plan's slice C seam is updated (B6). +- ADR 254: add the SQLite note from decision 1 (a target declares the types it distinguishes where the database's storage classes are shared). +- `docs/reference/codec-authoring-guide.md`: `dataType` is required on every descriptor; how to declare a data type with casts; the authoring entry; strict assembly. +- `docs/reference/error-reference.md`: the renamed code and messages. +- `packages/2-sql/2-authoring/contract-psl/README.md`: the paragraph on defaults in the ADR's words. +- `upgrade-instructions/pending/literal-types-column-defaults/`: app instructions gain the contract-form change for `int8number`/`bigintnumber` columns (re-run `contract emit`, then `db sign`); extension instructions are rewritten: declare a data type per codec, name it on the descriptor, casts replace accepted lists, `decodeJson` takes only the canonical form, the authoring entry replaces the tag registry entry, strict assembly. +- Every "literal type" in code, comments, docs and tests becomes "data type";

list against scalars only; nested list refused. -- `writeLiteral`: each type round-trips its own value; number `1.5` against `i8..i32, decimal` → `1.5`; text `"42"` against `i8..` → `42`; `1e21`-magnitude number prints without exponent; non-finite prints unquoted; JSON value prints as a `json` tag, quote fence when the text has a backtick; `undefined` when nothing matches. -- `describeDeclarations` wording. - -Descriptor (`framework-components/test/codec.types.test-d.ts`): `literalTypes` is optional and typed as the declaration union. - -Per pack inventory test (B2), seven files, one per pack. - -Codec coercion (`postgres/test`, `sqlite/test`, `relational-core/test`, `pgvector/test`): for each codec in B2's coercion list, `decodeJson` accepts each named shape and refuses the rest; float4/float8 non-finite round-trip through `encodeJson`/`decodeJson` and `encode`/`decode`; `sqlite/integer@1` refuses `2**53 + 1`. - -Registry (`6-adapters/postgres/test/control-mutation-defaults.test.ts`, SQLite equivalent): tag registry holds `sql`, `pg.sql` (or `sqlite.sql`) and `json`; `json` names literal type `json`. - -Interpreter (`contract-psl/test/interpreter.defaults.literal-types.test.ts`, replacing `interpreter.number-defaults.test.ts`), whole default object asserted: -- every Outcome column above;

`Decimal @default(42)` → `"42"`; `Jsonb @default([1, 2])` → JSON array (harmless consequence of the list arm; recorded); vector length mismatch → `PSL_INVALID_DEFAULT_LITERAL` with the codec's message; missing `descriptorFor` → `InternalError`. -- `interpreter.defaults.tagged-literal.test.ts`: `json` tag cases incl. `json\`null\``, invalid JSON, `json` on an `Int` column → incompatible, `json` inside a list on `Jsonb[]`. -- language server `completion-provider.test.ts:766` stays green unchanged. - -Prisma 7 (`contract-prisma7/test/defaults.test.ts`): `Int @default(1.5)` and `Int @default(100000000000000099)` → `PRISMA7_UNKNOWN_DEFAULT` with the incompatibility reason;

`pg/int8@1` beyond 2^53 prints every digit; `pg/float8@1` `NaN` prints `NaN`; jsonb object prints as a `json` tag; vector prints as a list; a codec naming nothing falls back as on `main`; the type-name resolution agrees with emit for every printed type. - -Journeys: the e2e test from B9 against a real database; the `infer-roundtrip-fidelity` jsonb case; `test/integration/test/number-defaults/psl-number-defaults.integration.test.ts` updated to descriptors with `literalTypes`; a parity pair `test/integration/test/authoring/parity/default-literal-types/` whose PSL and TypeScript emit identical contracts. +- Framework: `dataType()` validates ids; `DataTypeLookup`; each of the four assembly invariants fails with the named contributor and id; a codec descriptor without `dataType` fails to compile (test-d). +- Per pack: an inventory test asserting every registered codec's `dataType` and every registered type's cast sources against a table (Postgres, SQLite, relational-core adapted codecs, pgvector, postgis, arktype-json, Mongo). +- Casts: each cast in B3/B4 with its conversion (`pg/int2 → pg/int8`: `42 → "42"`; `pg/numeric → pg/float8`: `"1.5" → 1.5`, `"NaN" → "NaN"`; `pg/json → pg/jsonb` unchanged; vector list cast). +- Classifier per target: every boundary (16, 32, 64 bits, safe integer on SQLite, negative bounds, `-0`, leading zeros, trailing zeros, the three words, refused on SQLite). +- Codecs: `decodeJson` refuses every non-canonical shape it accepted on the branch; `int8number`/`bigintnumber` round-trip digit text and refuse past 2^53. +- Interpreter: every Outcome column and every error form above, whole default object asserted; the enum reference path; Prisma 7 reader parity. +- Printer: round trip for every Outcome column; the decode-check fallback for `'infinity'::timestamp`. +- Journeys: the branch's e2e, pgvector, infer round-trip and parity tests, updated to the new names; `pnpm fixtures:check` shows exactly the `int8number`/`bigintnumber` columns changing form and nothing else, after which the fixtures are re-emitted and committed. ## Definition of done -- All tests above green;

A codec whose type depends on the target that adopts it declares a `CodecDescriptorTemplate` instead, and the target names the type when it adapts the template — which is what the generic relational codecs do, since the same template is `pg/int4` on one target and `sqlite/integer` on another. Every descriptor in the repo now carries a provisional id, written exactly as the spec's tables will register it. Nothing registers a data type yet. ADR 254, spec B1.

A tag the family lowers itself sits in the same map under a reserved key, because it names no type. Assembly builds one lookup, refusing two declarations of an id, and checks the four things that span packs: a codec's type is registered, an entry's key and every type a cast takes values of are registered, no two entries claim one tag or one plain form, and a type a cast takes values of can be written. Nothing registers a type yet, so `registersDataTypes` is false and the checks stand down; the flag goes away once every pack declares. ADR 254, spec B1 and B2.

The written form is a union now: a tag and the plain string and boolean forms carry `parse`, and the number form carries the classifier instead, plus every type that classifier can return — which is also how assembly knows those types can be written, since the entry reading them is keyed under one of them. Also: the lookup takes a plain string, so the invariants need no casts; the duplicate-form error carries both contributors in its meta rather than a half-quoted fragment; the three extensions name their data type through a constant, as the targets do; and the unused empty lookup is gone.

A target that has no type for one of those leaves it out and the classifier returns nothing, which is how SQLite refuses a number no SQLite type holds. ADR 254, spec B4.

A codec names its type through the declaration, so a misspelling no longer compiles. Postgres follows PostgreSQL's own rule for a written number: a whole number takes the narrowest of int2, int4 and int8 that holds it, and anything wider, a fraction or one of the three words is a numeric, which int8 and the float types then cast from. SQLite holds a whole number in two types and has none at all for a number past 64 bits or a non-finite one, so its classifier returns nothing and the value is refused. A vector takes a written list through a list cast, the geometry type takes text, and the arktype document takes a JSON document; Mongo names a type per codec and nothing more.

The three words still pass through, so a written Infinity and a number too large stay distinct. The casts that read a number or numeral text likewise throw rather than pass an unexpected shape into a stored value.

The tagged-literal arms are built from the entries, so each tag carries its own documentation, and a tag that lowers its own body still lowers it. A refusal now names the two types and the casts the column's type has: `pg/int4 has no cast from pg/int8; it casts from pg/int2`, with ` at element N` inside a list. `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE` becomes `PSL_DEFAULT_TYPE_INCOMPATIBLE`, and a plain form this target has no type for — a boolean on SQLite — is reported under the same code. A text contract source now stores the canonical form as it read it, so the build no longer encodes it a second time; a TypeScript `.default(value)` still goes through the codec. ADR 254, spec B6.

See [ADR 254](../../../../docs/architecture%20docs/adrs/ADR%20254%20-%20Data%20types%20and%20casts.md). +- Every written default has a data type of its own, decided by what is written rather than by the column: a quoted string, `true`/`false`, a number whose type comes from its own size and precision, and a JSON document written `` @default(json`{ "plan": "free" }`) ``. The column's type takes the value when it is that type or declares a cast from it, so `Int @default(100000000000000099)` is refused before anything is decoded: `PSL_DEFAULT_TYPE_INCOMPATIBLE`, naming the cast the column's type would need.

The string may use any quote style, and whitespace, newlines, or comments may sit between the tag and the string. A backtick string may span lines and resolves only `` \` `` and `\\`, so `${` is ordinary text and needs no escape; `"` and `'` strings resolve the usual escapes. A backtick string is only valid after a tag; anywhere else it is `PSL_BACKTICK_STRING_REQUIRES_TAG`. A body that is exactly `now()` or `autoincrement()` (`` sql`now()` ``) is refused: write the named form, `@default(now())`. Any other body, including `NOW()` and `gen_random_uuid()`, is used as written. The body is canonicalized (line endings, a blank first and last line, common indentation) and used verbatim as the default expression. `sql` is registered by every SQL target; `pg.sql` (Postgres) and `sqlite.sql` (SQLite) are target-prefixed spellings of the same tag.

Those conversions are the casts a data type declares, which run before a codec sees the value. The three non-finite words stay the float types' JSON and wire form, because that is what those types hold. `pg/int8number@1` and `sqlite/bigintnumber@1` change form with their type: they write and read digit text now, refusing a magnitude past 2^53 with a message that names the limit their in-memory value has. Their JSON projection and the count aggregate's empty result follow. ADR 254, spec B5.

The `sql` lowering entry lives with the other authoring entries now, so every consumer — the two adapters, the language server, the fixture registry and the family's own entry — reads one surface. `escapePslString` and the numeral helpers live with the family's other shared implementations, where the printer and both targets can reach them. Every stack the repo builds, real or fixture, now carries its data types, so the reader and the printer resolve them the same way in tests as in a real stack. ADR 254, spec B5 through B7.

[PATCH 59/81] fix(psl): a caller cannot get an interpreter with no data types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The lookup was optional and fell back to an empty one, which is why the provider never passing it went unseen: every cast missed and only a real contract emit showed it. It is required now, as it already was on the reader for the earlier schema language, and a test loads a schema with a number default through the provider seam the CLI uses — the seam no package test crossed before. Reverting the provider's threading makes that test fail. A plain form the target has no data type for, which is a boolean on SQLite, now has a test for its code and its message.

ADR 254 gains the SQLite note — where a database's storage classes are shared by several logical types the target declares the types it distinguishes — and six corrections where it described something the implementation does differently: the float cast keeps the three words as text and refuses a magnitude no double holds, SQLite's classifier has two integer types, the authoring entry's real shape, the number entry's list of types its classifier returns, lowering tags being several under reserved keys, and what assembly's invariants actually check.

A cast may also refuse: the cast into the floating-point types refuses a magnitude no double holds rather than rounding it to `Infinity`, because the database refuses it too and storing `Infinity` would make a written number indistinguishable from a written `Infinity`. Casts are declared by the type that receives, never by the source, so there is at most one cast for any pair and the owner of a type is the only one who decides what it takes. That ownership rule is the one PostgreSQL uses for its own cast table, and the rule is all we borrow: these casts are between our data types, applied in the framework before a value is stored or sent, and they model nothing about what the database can convert. Nothing central computes convertibility, because only a type's owner knows what its database or extension can take. There is no list data type.

Declare the types a column of this codec accepts as a `@default` literal: +Every descriptor names the type it represents: ```ts -import { - integerLiteralTypesUpTo, - type LiteralTypeDeclaration, -} from '@internal/framework-components/codec'; - -class MyInt4Descriptor extends PostgresCodecDescriptor { - override readonly literalTypes: readonly LiteralTypeDeclaration[] = - integerLiteralTypesUpTo('i32'); - // … +import { pgvectorVector } from './data-types'; + +export class PgVectorDescriptor extends PostgresCodecDescriptor { + override readonly dataType = pgvectorVector.id; + override readonly codecId = VECTOR_CODEC_ID; + override readonly traits = ['equality'] as const; + override readonly targetTypes = ['vector'] as const; + override readonly paramsSchema: StandardSchemaV1 = vectorParamsSchema; + override factory(params: VectorParams): (ctx: CodecInstanceContext) => PgVectorCodec { + return () => new PgVectorCodec(this, params.length); + } } ``` -The ten type names are `string`, `boolean`, `i8`, `i16`, `i32`, `i64`, `bigint`, `decimal`, `float` and `json`. A written number's type comes from its own size and precision, never from the column, so `42` is an `i8` on every column and `100000000000000099` an `i64`; naming a chain is what makes a too-large value an incompatibility rather than a decode failure. `integerLiteralTypesUpTo(name)` gives the chain from `i8` up to and including `name`. +`dataType` is `abstract readonly dataType: DataTypeId` on `CodecDescriptorImpl`, so a descriptor that leaves it off does not compile. `DataTypeId` is a branded string: the only way to make one is `dataTypeId('owner/name')`, which `dataType()` calls for you, so reference the declaration's `.id` rather than writing the string again. + +Several codecs may represent one type. `pg/int8@1` and `pg/int8number@1` both name `pg/int8`; they differ in the in-memory value they produce, and both store the type's one canonical form. + +Assembly checks the ids across packs.

Casts are declared by the type that receives, never by the source, so there is at most one for any pair and a type's owner is the only one who decides what it takes. A written value is admitted when its type is the column's type or the column's type casts from it; the cast runs before the codec sees anything. -A declaration may also name a list of element types, which lets a column that is not a list take a PSL list — this is how a vector column takes `@default([0.1, 0.2, 0.3])`: +This replaces the per-codec list of accepted shapes. Delete `literalTypes` from every descriptor, delete any import of `LiteralTypeDeclaration` or `integerLiteralTypesUpTo`, and move each conversion into the receiving type's cast: ```ts -override readonly literalTypes: readonly LiteralTypeDeclaration[] = [ - { list: [...integerLiteralTypesUpTo('i64'), 'bigint', 'decimal'] }, -]; +const asNumeralText: Cast = (value) => + typeof value === 'number' ? numeralText(value) : wrongShape(value, 'a number'); + +export const pgInt8: DataType = dataType('pg/int8', { + casts: { [pgInt2.id]: asNumeralText, [pgInt4.id]: asNumeralText }, +}); +``` + +Declaring no cast is a decision, not an omission. `pg/int4` declares none from `pg/int8`, so a number too wide for the column is refused before anything is decoded: + +```text +Field "N.count": pg/int4 has no cast from pg/int8; it casts from pg/int2 ``` -Declaring nothing is a decision, not an omission: the column then accepts no literal default, and a `@default` on it is refused with `PSL_DEFAULT_LITERAL_TYPE_INCOMPATIBLE` naming `no literal defaults`. +A cast may refuse the value it is handed, with a structured error carrying `why` and `fix`; the refusal surfaces as `PSL_INVALID_DEFAULT_LITERAL` at the written value. -A descriptor that adapts another (`postgresCodec(...)`, `sqliteCodec(...)`) forwards the wrapped descriptor's declaration; a hand-written adapter must copy `literalTypes` across as it copies `traits` and `targetTypes`. +There is no list data type. A type whose single value holds several elements declares a `listCast` instead: `of` is the set of types an element may be, and `cast` receives the elements' canonical forms in written order. This is how a vector column takes `` @default([0.1, 0.2, 0.3]) ``: -## `decode-json-accepts-every-named-shape` +```ts +export const pgvectorVector: DataType = dataType('pgvector/vector', { + listCast: { + of: [pgInt2.id, pgInt4.id, pgInt8.id, pgNumeric.id], + cast: (elements) => elements.map(elementNumber), + }, +}); +``` -Each literal type fixes the shape of the value it produces: `i8`, `i16` and `i32` give a JSON number; `i64` and `bigint` give digit text, because a JSON number rounds past 2^53; `decimal` gives decimal text with its trailing zeros; `float` gives the word `NaN`, `Infinity` or `-Infinity`; `string` gives the text; `boolean` a boolean; `json` the parsed document. Converting between those shapes and the codec's own stored form is the codec's job — no contract source branches per codec. +Assembly refuses a cast whose source type no contract source can write, with `CONTRACT.DATA_TYPE_NOT_WRITABLE`: such a cast could never be exercised. -So a codec whose stored form differs from a named type's shape widens `decodeJson`. `pg/int8@1` stores digit text and names `i8` to `i64`, so it takes a whole JSON number as well: +## `decode-json-takes-only-the-canonical-form` + +A data type names one **canonical form**: the single JSON shape `contract.json` stores for its values. `pg/int8` stores digit text, `pg/int4` a JSON number, `pg/jsonb` the document. Every codec of a type stores and reads exactly that form. + +So `decodeJson` takes that form and nothing else, and `encodeJson` produces it. Remove every branch a codec had for a shape it does not itself write — the cast has already produced the canonical form by the time the codec is called: ```diff - decodeJson(json: JsonValue): bigint { -- if (typeof json !== 'string') { -+ if (typeof json !== 'string' && typeof json !== 'number') { - throw myError('RUNTIME.DECODE_FAILED', 'value must be a decimal string or a whole number'); + decodeJson(json: JsonValue): number { +- if (typeof json === 'number') return decodeInt8(json); + if (typeof json !== 'string') { +- throw myError('RUNTIME.DECODE_FAILED', 'value must be decimal text or a whole number'); ++ throw myError('RUNTIME.DECODE_FAILED', 'database JSON value must be decimal text'); } return decodeInt8(json); } ``` -The mirror case is a number-valued codec that names `i64`: it must read digit text, and refuse text past `Number.MAX_SAFE_INTEGER` with a message naming that limit rather than rounding. `isNumeralText` and `isNonFiniteText`, exported from `@internal/framework-components/codec`, recognise the text a numeric literal carries; use them instead of a local regex so the codec and the classifier cannot drift. +Where two codecs of one type previously stored different shapes, they now share the type's form. `pg/int8number@1` and `sqlite/bigintnumber@1` store digit text like their `bigint`-valued siblings, and refuse text past 2^53 as a limit of their own representation. + +A codec still validates what the column's parameters constrain, on the canonical form: `vector(3)` refuses four elements, `numeric(10,2)` refuses a third decimal place. A refusal is reported as `PSL_INVALID_DEFAULT_LITERAL` carrying the codec's own message, and `contract infer` calls the codec on what it is about to print, falling back to the raw expression when it throws. -A codec that validates in `decodeJson` still may: a literal the codec refuses is reported as `PSL_INVALID_DEFAULT_LITERAL` carrying the codec's own message. `contract infer` calls `decodeJson` on what it is about to write and falls back to the raw expression when it throws, so a value the codec cannot read is never printed as a literal. +## `the-authoring-entry-replaces-the-tag-registry-entry` -## `default-literal-tag-entry-is-a-union` +PSL support for a data type is an **authoring entry**, contributed by the pack that owns the type under `authoring.dataTypes` and keyed by the type's id. It replaces the entry a pack used to register in the default-literal tag registry. -`ControlDefaultLiteralTagEntry` is now: +An entry has a **written form**, a `print` that is the reverse of reading it, and `documentation` the language server shows: ```ts -type ControlDefaultLiteralTagEntry = - | ControlDefaultLiteralTagLoweringEntry // usage, documentation, lower(...) - | ControlDefaultLiteralTagTypeEntry; // usage, documentation, literalType +export function postgresDataTypeEntries(): Readonly> { + return { + [pgText.id]: { + written: { kind: 'plain', syntax: 'string', parse: (text) => text }, + print: (value) => String(value), + documentation: 'Text.', + }, + [pgJson.id]: { + written: { kind: 'tag', tag: 'json', parse: parseJsonBody }, + print: printJsonBody, + documentation: 'Reads the body as a JSON document and stores it as the default value.', + }, + }; +} ``` -A lowering entry is unchanged: it turns its body into a default itself, as `` sql`...` `` does. A literal-type entry names the literal type its body is read as, and the body then goes through the column's codec like any other literal — `jsonDefaultLiteralTagEntry()`, exported from `@internal/framework-components/codec`, is the `` json`...` `` tag that Postgres and SQLite register. +There are four written forms: -Code that reads `entry.lower` must narrow first: +- `{ kind: 'tag', tag, parse }` — a qualified name followed by a body in any of PSL's quote styles.

This is the one form that yields several types, so instead of `parse` it carries a classifier that picks the type from the digits and returns the canonical form with it, plus `types`, every type the classifier can return.
