Fixes false language-server diagnostics for valid PSL schemas that contract emit accepts, including the schema generated by prisma orm init.

Changes

Replace constructor-identity checks in all 11 attribute combinators with existing kind-based AST casts.
Add an integration regression comparing CLI emission with the LSP diagnostic pipeline across the internal-parser/public-interpreter boundary. Cover the init schema, literal defaults and mapped names, and genuine invalid-function diagnostics.

Why

The LSP parses with its own parser and passes the artifacts to the project's interpreter. Those packages can contain separate AST class copies, so instanceof rejects valid function calls, arrays, and literals. Emission works because its parser and interpreter share class identities. Kind-based casts preserve validation without requiring constructor identity.

Scope: Attribute argument validation and regression coverage only; no schema syntax or emission behavior changes. Existing projects need updated ORM packages because the checks run in the project-loaded interpreter.

Verification

Confirmed the regression fails before the fix with the seven reported init-schema diagnostics.
Three integration cases pass after the fix.
PSL parser, language-server, SQL PSL, and Mongo PSL suites pass: 1,556 tests.
Parser, language-server, and integration-project typechecks pass.
Parser lint, new-test lint, and changed-file diagnostics pass.

Summary by CodeRabbit

Bug Fixes
- Improved parsing consistency for boolean, numeric, string, JSON, list, record, identifier, field, entity, and function-reference values.
- Preserved existing validation rules and diagnostics while improving syntax handling.
Tests
- Added integration coverage confirming that language-server diagnostics match contract validation results across valid and invalid schemas.

📝 Walkthrough

Walkthrough

The parser combinators now cast syntax nodes before reading values. A new integration test compares contract emission results with language-server diagnostics using temporary Prisma projects.

Changes

AST cast compatibility and parity validation

Layer / File(s)	Summary
Syntax-node casting in combinators `packages/1-framework/2-authoring/psl-parser/src/attribute-spec/combinators/*.ts`	Combinators use AST cast methods for literals, identifiers, arrays, objects, and function calls. Existing validation and diagnostics remain unchanged.
CLI and language-server parity test `test/integration/test/authoring/lsp-emit-parity.integration.test.ts`, `test/integration/test/fixtures/cli/cli-test-app/fixtures/lsp-emit-parity/prisma.config.ts`	The integration test compares emission exit codes with language-server diagnostic codes for valid and invalid schemas. The fixture provides the ORM contract configuration.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to 84b50

This change aligns language-server diagnostics with contract emission for valid schemas. The remaining risk is limited to unclear documentation for running the parity suite and does not indicate a production behavior issue.
