# 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.
