SARVA System for Aligned Runtime Verification & Authorization
SARVA evaluates every AI action against fixed policy rules — safety, compliance, and ethical boundaries — and resolves it to one of three outcomes: allow, escalate, or block.
If any gate determines the action should not proceed, it stops there. Nothing after a blocked gate ever runs.
Is this action ethically permissible? Harm prevention, autonomy, safety.
Has this agent been authorized to perform this type of action?
Is this a recognized action type? No prohibited payloads.
Does active policy and role permit this specific request right now?
Permanent? Re-validate authority. Re-verify policy. No stale trust.
Every decision is written to a tamper-evident, append-only ledger. Regulators require provable records, and enterprise buyers demand a complete audit trail.
Every decision resolves to one of three outcomes.
Action is authorized and proceeds. The decision is logged.
Action requires additional evaluation before execution. May resolve to allow, escalate further, or block.
Action violates policy and is blocked before execution. The decision is recorded.
Re-validates authorization at the execution boundary. Fails closed on mismatch.
Time-bound validation with defined decay windows.
Policy hash at binding must match the active hash at execution.
Each agent re-establishes authority at every binding point.
Prevents authority escalation across chained bindings.
Every decision is recorded with full context and policy validation. Enforcement occurs before execution.
Every decision recorded with full context, timestamps, and policy references.
Each action evaluated against active policy before execution.
Violating actions are halted at the decision boundary with full trace.
Other tools live inside the model. SARVA + Cosmos live on the boundary of execution, enforcing policy before any action runs.
