+# Hybrid Logical Clock Library Charter
+
+## Mission
+Provide deterministic, monotonic HLC timestamps for distributed ordering.
+
+## Responsibilities
+- Maintain HLC core logic, parsing, and serialization.
+- Ensure TimeProvider usage for deterministic tests.
+- Track sprint tasks in `TASKS.md` and update the sprint tracker.
+
+## Key Paths
+- `HybridLogicalClock.cs`
+- `HlcTimestamp.cs`
+- `PostgresHlcStateStore.cs`
+
+## Required Reading
+- `docs/modules/platform/architecture-overview.md`
+- `docs/implplan/permament/SPRINT_20251229_049_BE_csproj_audit_maint_tests.md`
+
+## Working Agreement
+- 1. Keep timestamps monotonic and causally ordered.
+- 2. Use invariant parsing/formatting.
+- 3. Update `TASKS.md` and sprint statuses when work changes.
