/**
 * Timeback Primitives Schemas
 *
 * Zod schemas for runtime validation of core types.
 *
 * ## Organization
 *
 * This file contains Zod schemas that mirror the TypeScript types in `../primitives.ts`.
 * For clarity, schemas are grouped by scope:
 *
 * 1. **Shared utilities** - Date/time validation, etc.
 * 2. **Shared Timeback schemas** - Used across multiple protocols
 * 3. **OneRoster-specific schemas** - Used only by OneRoster
 * 4. **QTI-specific schemas** - Used only by QTI
 * 5. **IMS Global schemas** - 1EdTech standard types
 *
 * Protocol-specific schemas are kept here (rather than in protocol files) because
 * they're low-level building blocks imported by the protocol schema files.
