ADDED Requirements

Requirement: Define PostgreSQL tables with Drizzle ORM

The package SHALL export Drizzle ORM table definitions using pgTable from drizzle-orm/pg-core, with proper column types, constraints, and defaults targeting PostgreSQL.

Scenario: Table exports are available

• WHEN another package imports from @workspace/schema
• THEN all Drizzle table definitions SHALL be accessible as named exports

Scenario: Table uses standard column types

• WHEN a column is defined in a Drizzle table
• THEN it SHALL use a drizzle-orm/pg-core column type (e.g., text(), integer(), timestamp(), uuid(), boolean())

Requirement: Define PostgreSQL enums

The package SHALL support PostgreSQL enum definitions using pgEnum from drizzle-orm/pg-core for constrained string fields.

Scenario: Enum is defined and exportable

• WHEN an enum is created with pgEnum
• THEN it SHALL be exportable and usable as a column type in table definitions

Requirement: Define table relations

The package SHALL define Drizzle relations (relations from drizzle-orm) between tables, supporting one-to-many, many-to-one, and many-to-many relationships.

Scenario: Relation links two tables

• WHEN a relation is defined between two tables
• THEN the related fields SHALL be queryable via Drizzle's relational query API

Requirement: All schemas are co-located

The package SHALL colocate Drizzle table definitions, enums, and relations within the same directory structure under src/drizzle/.

Scenario: Single import for database concerns

• WHEN a consumer needs database schema
• THEN it SHALL import from @workspace/schema without accessing internal paths
