Silent mutation risk

Silent mutation risk is the chance that state changes without an explicit, inspectable trail. High-risk systems can overwrite or drop facts without leaving evidence.

Before vs after

Before: a contact field changes after an agent run and nobody can tell when or why. After: every field change is an observation, and lineage can be queried by entity and timestamp.

# Inspect mutation trail for one entity
neotoma observations list --entity-id <entity_id>

# Verify relationship links for source context
neotoma relationships list --entity-id <entity_id>

Deterministic systems prevent silent mutation by design through auditable change logs and versioned history. See conflicting facts risk, false closure risk, and deterministic memory.
