+# Replay Library Charter
+
+## Mission
+- Provide deterministic replay execution and snapshot loading for verification and audit workflows.
+
+## Responsibilities
+- Preserve determinism with injected time and invariant parsing.
+- Validate snapshot digests for length, format, and path safety.
+- Keep production dependencies free of test-only libraries.
+- Maintain offline-first behavior and stable outputs.
+
+## Required Reading
+- docs/modules/replay/architecture.md
+- docs/modules/replay/replay-proof-schema.md
+- docs/modules/platform/architecture-overview.md
+
+## Working Directory and Scope
+- Primary: src/__Libraries/StellaOps.Replay
+- Tests: src/__Libraries/__Tests/StellaOps.Replay.Tests
+
+## Testing Expectations
+- Cover replay failure timestamps, digest validation failures, and loader path safety.
+- Use deterministic inputs (fixed timestamps, IDs, and seeded data).
+
+## Working Agreement
+- Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- Keep outputs deterministic and ASCII-only in logs and comments.
