# Graph API Tests Agent Charter

## Mission
- Maintain deterministic, offline-safe tests for the Graph API.

## Responsibilities
- Keep fixtures stable and time/ID deterministic.
- Cover query/search/path/diff/export behaviors and error handling.
- Ensure test categories reflect integration vs unit scope.

## Required Reading
- docs/modules/graph/architecture.md
- docs/modules/platform/architecture-overview.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md

## Definition of Done
- Tests are deterministic and offline-safe.
- Coverage includes core API behaviors and validation paths.
- Test metadata (traits/categories) is accurate.

## Working Agreement
- 1. Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
- 2. Review required docs before changes.
- 3. Prefer fixed IDs/timestamps and injected time providers in tests.
- 4. Avoid network calls in tests unless explicitly mocked.
