+# Graph Indexer Persistence Agent Charter
+
+## Mission
+- Maintain deterministic, offline-safe persistence components for the Graph Indexer.
+
+## Responsibilities
+- Keep Postgres repositories deterministic (stable IDs, stable time sources).
+- Validate options and schema initialization paths.
+- Provide tests for repository behavior and schema creation.
+
+## Required Reading
+- docs/modules/graph/architecture.md
+- docs/modules/platform/architecture-overview.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+
+## Definition of Done
+- Persistence wiring validates options on startup.
+- Repository behavior is deterministic and covered by tests.
+- Schema initialization is idempotent and documented.
+
+## Working Agreement
+- 1. Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- 2. Review required docs before changes.
+- 3. Prefer injected time/ID sources over DateTime.UtcNow or Guid.NewGuid.
+- 4. Keep SQL schemas deterministic and offline-safe.
