📝 Walkthrough

Walkthrough

Changes

UUID validation is now supported through @uuid and isUuid. Versions 4 and 7 are validated in the language layer and executed through Zod. Unit, schema, CLI, and ORM tests cover valid and invalid UUID values.

UUID validation

Layer / File(s)	Summary
Language declarations and argument validation packages/language/res/stdlib.zmodel, packages/language/src/utils.ts, packages/language/src/validators/..., packages/language/test/*	Defines @uuid and isUuid, extracts numeric arguments, restricts explicit versions to 4 and 7, and tests supported and unsupported versions.
Zod UUID execution and schema coverage packages/zod/src/utils.ts, packages/zod/test/schema/*, packages/zod/test/factory.test.ts, packages/cli/test/db/pull.test.ts	Maps UUID validation to Zod, adds User.extId, and tests invalid and valid UUID values plus validation preservation.
ORM validation coverage tests/e2e/orm/validation/*	Tests custom isUuid validation and field-level @uuid and @uuid(7) checks during create and update operations.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🟡 Moderate · up to 96af4

The change adds UUID version validation, but unversioned validation can still reject valid UUID v7 values, and non-literal version expressions may bypass the intended 4/7 restriction. This creates bounded correctness risk, so the PR is not merge-ready until the behavior is fixed or explicitly accepted.

In `@packages/language/res/stdlib.zmodel`:
- Around line 657-661: Add an invocation checker for isUuid that validates
constant version arguments and rejects any version other than 4 or 7 during
schema validation; update the schema tests to cover an invalid version such as
5, while preserving valid nullable or omitted version behavior.

In `@packages/zod/src/utils.ts`:
- Around line 83-90: Update the `@uuid` handling in the attribute switch to call
result.uuid() when version is undefined, while preserving result.uuidv4() and
result.uuidv7() for explicit versions. Add tests covering unversioned v4 and v7
values and rejecting a v4 value with `@uuid`(7).
