Policy engine contract

Scope​

The policy engine routes event classes to storage and ledger targets based on deterministic rule sets.

Invariants​

  • Policy decisions must be deterministic for identical inputs.
  • Policy outputs must be auditable and reproducible.
  • Sensitive person/job data must never be routed to public chains.

Failure Modes​

  • Non-versioned policy rules causing decision drift.
  • Ambiguous rule precedence returning inconsistent targets.
  • Incomplete validation of event class before policy execution.

Out of Scope​

  • Proprietary policy rule content.
  • Internal confidence scoring or optimization logic.
  • Partner-specific policy overrides.
