Traceable World State: A Provenance-Aware State Representation and Deterministic Replay Framework for Robotic Systems
We present Traceable World State (TWS), a middleware-neutral semantic representation and reference runtime for provenance-aware robot world state.

Key points
- Robotic systems operating over extended tasks must maintain a world state assembled from observations arriving at different times, with varying confidence and potential revisions.
- Validated update operations transform snapshots immutably, ordered updates support deterministic replay, and a canonical SHA-256 hash chain ensures tamper-evident logs.
- We evaluate TWS through schema conformance, complete state lifecycles, deterministic replay, and fault injection.
- Passing 38 tests across Python 3.10-3.14, the framework detects record corruptions, broken hash links, sequence discontinuities, and world mismatches.
