+# Messaging Postgres Transport Agent Charter
+
+## Mission
+- Provide PostgreSQL-backed messaging transport with reliable queue and stream semantics.
+
+## Responsibilities
+- Keep SQL safe, parameterized, and deterministic across environments.
+- Ensure schema/table naming is validated or quoted to avoid injection and drift.
+
+## Required Reading
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/router/architecture.md
+
+## Working Directory & Scope
+- Primary: src/Router/__Libraries/StellaOps.Messaging.Transport.Postgres
+- Allowed shared projects: src/Router/__Libraries/StellaOps.Messaging
+
+## Testing Expectations
+- Add tests for queue leasing, retry semantics, cache TTL, event stream ordering, and idempotency.
+- Keep tests offline-friendly; use opt-in container fixtures if needed.
+
+## Working Agreement
+- Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- Keep outputs deterministic and avoid non-ASCII logs.
