What this PR does

Generic-block values now bind the same typed expression grammar attributes use, and the legacy PslBlockParam DSL is retired in the same change that migrates every consumer. Block authors declare values with fixedBlock({ parameters }) or entriesBlock({ value, allowBare }), get inferred outputs through InferBlock, and lowering receives a typed envelope (ParsedPslExtensionBlock<Values>) — never raw parameter text.

The design in five decisions

  • Source and semantics are separate products. The print block keeps ordered source entries { expression?, span } strictly for rendering; validated values live only in the typed envelope. The printer renders provenance verbatim and never executes spec or reference factories; lowering never reads print text.
  • Collect everything, then interpret. buildSymbolTable collects all declarations first, then binds each registered block's spec factory against the complete table and publishes only successful envelopes in a symbol-keyed parsedBlocks map. Forward references work, invalid blocks keep their syntax for recovery/tooling but never lower, and every value/attribute failure is reported exactly once at its original span.
  • Core stays parser-blind. AuthoringPslBlockDescriptor carries one erased callable spec field; a single parser-owned boundary (blockSpecFactoryOf) restores the type, mirroring the existing attribute-factory erasure.
  • Policies file at their selected target. SQL core gains an optional pslPlacement hook (SqlPslEntityPlacementOutput); PostgreSQL registers it on policies so a policy whose target resolves through top-level fallback lands in the target's physical namespace, with destination-keyed collision checks. Other entities keep lexical placement.
  • Family and native enums keep their distinct contracts. Family enums accept bare members and native JSON through the new shared jsonValue() rule with codecs deciding meaning (decode, post-decode uniqueness, empty/unknown-codec checks unchanged); native enums remain explicit strings. Prisma 7 constructs trusted envelopes directly and owns duplicate-key reporting for its dialect.

Supported policy predicates are optional(str()) — previously accepted omissions and inferred documents stay valid; unsupported predicate keys are rejected as unknown fixed keys at parse time.

What was removed

PslBlockParam*, the five-way PslExtensionBlockParam* union, variadicParameters, both legacy validators (psl-extension-block-validator.ts, validateExtensionBlockFromSymbol), the printer's descriptor-kind rendering and codec reparse, and Postgres's raw-reading helpers (readValueParam, readListRefParams, unwrapQuotedString, native-enum JSON.parse). A tests-inclusive inventory (grep evidence in the branch history) shows zero survivals and no compatibility exports.

Editor behavior

Block-key completion and attribute signatures read the same bound specs validation uses, via metadata only (spies pin that inspection never parses or resolves). Registered block value/reference errors now surface in the parse-plus-symbol pipeline; family semantics (codecs, @@rls, placement, collection uniqueness) keep their owners. One deliberate regression: declaration snippets no longer pre-fill key lines (no symbol exists to bind a spec before the block is authored); keys complete inside the block immediately after insertion.

Docs

ADR 255 records the shipped design; ADR 126's block-parameter sections carry supersession notes; ADRs 231/249/246 got minimal factual corrections; extension upgrade instructions live under upgrade-instructions/pending/typed-block-value-specs/.

Verification

Full workspace build, root typecheck 169/169, lint:deps, test:packages (1334 files / 18001 tests), test:integration (4254 tests), test:e2e (123 tests), and pnpm fixtures:check with zero churn — emitted contracts and generated types are byte-equivalent. Inference round-trips parse their own output through the real pipeline to equal IR. Manual QA covered extension-author ergonomics, schema-author diagnostics, and the new-block editor flow.

Two pre-existing issues surfaced during the aggregate gates and are reported separately, not addressed here: a missing turbo edge between integration-tests#typecheck and @prisma/orm-postgres:build (nested-manifest dependency invisible to the graph), and a parallel-run flake in the CLI migration-snapshot suite.

📝 Walkthrough

Walkthrough

This change replaces parameter-table descriptors for top-level PSL blocks with typed specifications. The parser publishes typed envelopes after declaration collection. The printer renders producer-built entries. Language-server and SQL flows pass parsed envelopes to completion, interpretation, and lowering.

Changes

Typed block specifications and parser lifecycle

Layer / File(s) Summary
Block contracts and value specifications
packages/1-framework/1-core/framework-components/src/shared/*, packages/1-framework/2-authoring/psl-parser/src/block-spec/*, packages/1-framework/2-authoring/psl-parser/src/attribute-spec/*		 Descriptors now use spec factories with fixedBlock or entriesBlock. The new jsonValue() rule parses native JSON-compatible literals. Parsed envelopes carry typed values, spans, attributes, and block identity.
Collect-first interpretation and publication
packages/1-framework/2-authoring/psl-parser/src/symbol-table.ts, packages/1-framework/2-authoring/psl-parser/test/*		 The symbol table interprets registered blocks after collecting declarations. Successful results are returned in parsedBlocks; invalid blocks retain syntax symbols but have no envelope. Tests cover value binding, diagnostics, references, attributes, type inference, and derivation.
Public API and migration documentation
packages/1-framework/1-core/framework-components/src/exports/*, packages/1-framework/2-authoring/psl-parser/src/exports/*, docs/architecture/*, docs/reference/error-reference.md, upgrade-instructions/pending/typed-block-value-specs/extension/instructions.md		 Exports for parameter-descriptor types and standalone validators are removed or replaced. ADRs and upgrade instructions describe the typed-spec lifecycle and producer-only print shape.

Printing and editor integration

Layer / File(s) Summary
Provenance-based printing
packages/1-framework/2-authoring/psl-printer/src/*, packages/1-framework/2-authoring/psl-printer/test/*		 The printer renders ordered source entries and block attributes without codec lookup or value interpretation. Tests verify verbatim rendering and descriptor registration checks.
Language-server envelope flow
packages/1-framework/3-tooling/language-server/src/*, packages/1-framework/3-tooling/language-server/test/*		 Pipeline and project artifacts expose parsedBlocks to editor features. Fixed-block completion uses the resolved spec; generic snippets no longer prefill parameter keys.

Family and SQL lowering

Layer / File(s) Summary
Family enum consumers
packages/2-mongo-family/*, packages/2-sql/9-family/*		 Enum factories consume parsed values and parameter spans. Enum specifications use entriesBlock with jsonValue() and support bare-member sentinels where configured.
SQL envelope and placement flow
packages/2-sql/1-core/contract/*, packages/2-sql/2-authoring/contract-psl/*		 SQL interpretation threads parsed envelopes into factories and field contexts. Resolved model references carry namespace and table coordinates. Outputs may select a destination namespace, and duplicate destination entities produce diagnostics.
Postgres policy and enum behavior
packages/3-targets/3-targets/postgres/src/core/*, packages/3-targets/3-targets/postgres/test/*, packages/2-sql/2-authoring/contract-prisma7/*		 Postgres block descriptors use typed specs. Policy lowering uses target model coordinates and placement hooks. Prisma 7 reads selected entries from syntax AST and reports duplicate entries. Tests cover enum and policy lowering, placement, and round trips.

Merge Risk: ⚪ Minimal · up to 00651

The typed block migration and its printer, language-server, SQL, and family updates have no established material failure path; the PR is mergeable subject to ordinary checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 00651

The normal parsing path separates source text from validated values, and no attacker-accessible bypass was established. The changed contracts and policy placement still warrant design review because their full downstream exposure is not established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — Schema-authored block values can affect generated SQL entities through typed interpretation; placement can affect their namespace. The evidence does not establish an independently attacker-controlled route to a privileged service or credential.

Trust Boundaries and Controls

  • observed — In the normal provider path, successful parsed envelopes—not printable expression entries—cross into SQL lowering; invalid blocks without envelopes are skipped.

Resilience and Maintainability Implications

  • inferred — A direct caller could supply a parsed map inconsistent with its symbol table, because the interpreter selects the supplied map without a provenance check. No evidence establishes that untrusted schema input can do so through the normal provider.

Hardening Proposals

  • proposed — If the direct interpreter API is intended for callers across a trust boundary, bind supplied envelopes to the current symbol table or derive them inside the interpreter.

375-401: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a namespace-first case to the parity test.

This test compares deriveParsedBlocks key order against the lifecycle map only for a source whose blocks are all top-level. The two walks iterate differently when a namespace block is declared before a top-level block. Add a fixture that declares a registered block inside a namespace ahead of a top-level registered block, so the parity claim is exercised for the case that can diverge. See the related comment on packages/1-framework/2-authoring/psl-parser/src/block-spec/derive.ts.

feat(framework-components): erase block specs and split source from t…
60fdd4c 
…yped envelope

Replace AuthoringPslBlockDescriptor.parameters/variadicParameters with one
erased callable spec field, validated as a function at registration.
PslExtensionBlock becomes a source/print-only shape whose entries carry
expression text and span; interpreted values travel through the new generic
ParsedPslExtensionBlock envelope. Enum classification now inspects typed
values instead of raw JSON text. The legacy extension-block validator and
the retired parameter DSL types are removed without compatibility aliases.

caa8160 
…Value rule

Add parser-owned fixedBlock/entriesBlock binders over the shared Param
vocabulary, InferBlock inference, the BlockSpecContext factory contract, and
interpretExtensionBlock, which binds a registered block straight from its
AST entries into the generic ParsedPslExtensionBlock envelope with precise
expression/entry/block spans. Block attribute factories now receive the same
context. The shared jsonValue() rule reads native JSON-compatible literals
recursively from the expression AST, leaving quoted-object json() untouched.
Block reconstruction shrinks to source/print provenance, and the legacy
validateExtensionBlockFromSymbol bridge is gone with the core validator it
wrapped.

fix(psl-parser): keep user-authored block keys as own record entries
8737037 
Records keyed by user-authored names - interpreted block values, parameter
spans, interpreted attributes, jsonValue object literals, and source-entry
reconstruction - are now prototype-free, so a member or object key named
__proto__ binds as an ordinary own entry instead of silently vanishing into
(or mutating) the record prototype. Regressions cover fixed and entries
blocks with __proto__/constructor/toString keys, the bare sentinel for a
bare __proto__ member, and a jsonValue "__proto__" object key with the
prototype asserted unpolluted.

feat(psl-parser): interpret blocks after complete collection and publ…

…ish typed envelopes

buildSymbolTable now walks every accepted block after all declarations are
collected: it binds the registered descriptor spec factory with the complete
symbol table, interprets values and attributes through the block-spec
interpreter, and returns successful envelopes in a symbol-keyed parsedBlocks
map. Invalid blocks get no entry while keeping syntax and source provenance;
unregistered blocks are never interpreted. The interpreter is the single
owner of block value and attribute diagnostics: reconstruction no longer
reports duplicate members, so each failure surfaces exactly once with its
original span. BlockSpecFactory now states that spec outputs are records,
which lets the erased flow publish envelopes without a cast.

Add SqlPslEntityPlacementOutput with its structural guard, following the
value-set derivation hook convention: a pack entity-type output may pick the
destination namespace for its lowered row while entityKind and key stay
fixed by the generic walk. ResolvedPslModelRefs now carries the full storage
coordinate - namespaceId alongside tableName - projected from the selected
declaration identity.

feat(sql-contract-psl): lower typed block envelopes with hook-selecte…
3ce7010 
…d placement

The extension-block walk now consumes the parser-derived typed envelopes:
invalid blocks never reach lowering, checked model references project onto
their selected declaration coordinate through the coordinate-keyed model
mappings (no bare-name lookup), and each built entity files as a
LoweredPackEntity row at the pslPlacement-selected destination - lexical
owner without the hook - with cross-owner collision checks at the
destination and derived value-sets riding the same coordinate.
requiresModelAttribute enforcement reads the selected declaration too,
covering top-level fallback and wrong-kind shadowing while keeping its
diagnostic code and parameter span. The enum path passes envelopes through
to the factory without changing family enum semantics; a non-JSON member
value is now the shared grammar diagnostic rather than a lowering reparse.

docs: close out shared PSL value specifications (prisma#30485)
75c1460 
Close out shared PSL value specifications after prisma#30344 and prisma#30381
merged. Reconcile the existing architecture documentation with the
shipped binder-owned reference resolution and consumer-owned block
interpretation, and record the final retro.

Linear tracking was explicitly waived. This PR changes documentation
only; it introduces no runtime behavior, tests, or new architectural
decisions.

## Close-out evidence

- Both implementation slices merged. [Final implementation
CI](https://github.com/prisma/orm/actions/runs/36449629946) passed
build, typecheck, lint, coverage, all package/integration shards,
fixtures, e2e, examples, and Supabase acceptance. All review threads on
prisma#30381 are resolved.
- Shared struct/map specs replace the old block-value DSL; typed
outputs, bare enum members, codec behavior, and independent semantic
checks have runtime/type and family integration coverage.
- Current reference tests cover forward declarations, namespace
precedence and fallback, sibling exclusion, selected identities, and
declared-role/unchecked-name alternatives. Existing completion,
signature, and printing regressions pass.
- Durable decisions remain in ADRs 231/249/254/255 and the parser
README. This PR corrects stale contexts and lifecycle descriptions,
including binder construction and diagnostic ownership. It removes the
unnecessary upgrade fragment: the project changed internal APIs, not
public APIs.
- The mandatory final retro is recorded in `drive/retro/README.md`:
establish phase ownership before disputed implementation, preserve
discriminated spec types, and verify downstream extensions and aggregate
CI rather than treating scoped passes as complete verification.

All 59 local project artifacts were classified as transient and archived
intact outside the active project directory. They were untracked, so
their archival produces no tracked project-file deletions or migrations.
No durable external project references required updates. Historical
manual QA remains archived with its protocol-only and pre-final-API
limitations; final regression tests and merged CI are the current
implementation evidence.

Cross-namespace inheritance, persisted full-coordinate variants, and new
block-value completion remain outside this project's scope.

Verification: source-checked API examples, `pnpm lint:docs`, and `git
diff --check` passed. No product tests were rerun for this
documentation-only close-out. The global Drive trace emitter could not
resolve `arktype`; no trace event was fabricated or global installation
modified.

## Summary by CodeRabbit

* **Documentation**
* Clarified that block declarations are collected before block values
and attributes are interpreted, using a complete symbol-table snapshot
for reference resolution.
* Updated architecture guidance on when unresolved-reference diagnostics
are reported and how they differ from block value and attribute
diagnostics.
* Added guidance on confirming review interpretations, preserving
specification details in typed APIs, and checking downstream extensions
and CI results.
