# 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-archived/implplan/2025-12-29-csproj-audit/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.
