Integrity surfaces
Canonical hashing
Binds exact bytes and normalized identity to the evidence record.
Append-only journal
Preserves sequence without silently replacing earlier state.
Restart and restore
Tests whether state survives restart, backup, and isolated restoration.
Memory Diff
Explains what changed between witnessed states.
Explanation receipt
Connects a result to its sources, transformations, and limitations.
Public V001 boundary
The public V001 reproduction material establishes an authority-null control surface around signed observations, append-only journaling, deterministic replay, restart, backup, restore, and the absence of action or promotion endpoints. It does not establish production V002 readiness.
