+# Concelier Astra Connector Tests Charter
+
+## Mission
+Validate Astra connector configuration, plugin registration, and mapping scaffolding with deterministic tests.
+
+## Responsibilities
+- Maintain `StellaOps.Concelier.Connector.Astra.Tests`.
+- Keep tests deterministic and offline-friendly.
+- Surface open work on `TASKS.md`; update statuses (TODO/DOING/DONE/BLOCKED/REVIEW).
+
+## Key Paths
+- `AstraConnectorTests.cs`
+
+## Coordination
+- Concelier connector owners (StellaOps.Concelier.Connector.Astra).
+
+## Required Reading
+- `docs/modules/concelier/architecture.md`
+- `docs/modules/concelier/link-not-merge-schema.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/implplan/permament/SPRINT_20251229_049_BE_csproj_audit_maint_tests.md`
+
+## Working Agreement
+- 1. Update task status to `DOING`/`DONE` in both corresponding sprint file and local `TASKS.md`.
+- 2. Keep tests deterministic (stable ordering, timestamps, IDs).
+- 3. Avoid network in tests; use fixtures and cached payloads.
+- 4. Log any cross-module edits in the sprint Execution Log.
