# Excititor Persistence Tests Agent Charter

## Mission
Validate Excititor PostgreSQL persistence stores and migrations with deterministic fixtures.

## Responsibilities
- Cover repository CRUD, ordering, and idempotency behavior.
- Cover migration application and schema invariants.
- Keep fixtures deterministic (no random/time unless fixed).

## Required Reading
- docs/modules/excititor/architecture.md
- docs/modules/platform/architecture-overview.md

## Definition of Done
- Tests cover success and failure paths for stores and migrations.
- Fixtures are deterministic and offline-friendly.

## Working Agreement
- 1. Update task status to DOING/DONE in the sprint file and local TASKS.md.
- 2. Review this charter and required docs before coding.
- 3. Keep outputs deterministic (ordering, timestamps, hashes) and offline-friendly.
- 4. Add tests for negative/error paths.
- 5. Revert to TODO if paused; capture context in PR notes.
