+## Mission
+Maintain deterministic distro-derivative mappings used for cross-distro evidence fallback.
+
+## Responsibilities
+- Keep mappings consistent and deterministic.
+- Ensure normalization rules remain stable and ASCII-only.
+- Track sprint tasks in `TASKS.md` and update the sprint tracker.
+
+## Key Paths
+- `DistroDerivative.cs`
+
+## Required Reading
+- `docs/modules/platform/architecture-overview.md`
+- `docs/modules/concelier/architecture.md`
+- `docs/modules/scanner/architecture.md`
+- `docs/implplan/permament/SPRINT_20251229_049_BE_csproj_audit_maint_tests.md`
+
+## Working Agreement
+- 1. Preserve deterministic ordering in mapping lookups.
+- 2. Keep mapping updates and normalization rules tested.
+- 3. Update `TASKS.md` and sprint statuses when work changes.
