+# AirGap Persistence Guild Charter
+
+## Working Directory
+- `src/AirGap/__Libraries/StellaOps.AirGap.Persistence`
+
+## Scope
+- PostgreSQL persistence for AirGap state and bundle version history.
+- Data source configuration, schema management, and repository wiring.
+- EF Core context scaffolding for AirGap data models.
+
+## Required Reading
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/airgap/bundle-repositories.md`
+- `docs/airgap/airgap-mode.md`
+
+## Working Agreements
+- Update task status in the sprint tracker and local `TASKS.md`.
+- Keep schema changes deterministic and migration-driven.
+- Use configured schema names consistently (no hard-coded schema drift).
+- Avoid cross-module edits unless the sprint explicitly permits them.
+
+## Testing Rules
+- Use Postgres test fixtures or Testcontainers; no network.
+- Mark integration tests as Integration, not Unit.
+- Keep data ordering deterministic with explicit ORDER BY clauses.
