No bare as casts in production TypeScript. Use blindCast (value) from @prisma-next/utils/casts as the auditable escape hatch, castAs (value) for declarative-only assertions, or rewrite to eliminate the cast. as const is exempt. Test files are exempt.
Cursor rule Codex
Avoid barrel files and unnecessary re-exports.

Never patch raw contract data in tests; use real emitted fixtures or a user-facing authoring surface.

The framework domain (packages/1-framework) carries no family- or target-specific vocabulary — types, fields, hooks, or strategy values. Enforced by lint:framework-vocabulary.

Prohibit inline type imports in source files.
Cursor rule Codex
Never use Linear's sub-issue (parentId) feature; use standalone issues with projects, milestones, relations, and labels instead.

PostgreSQL LATERAL and jsonagg rendering patterns.

Cursor rule Codex
Prefer object matchers over multiple individual expect().toBe() calls.
