Sealed system

Architecture

One ladder. No skipped states. No convenience logic. The same engine in every node.

Closed loop

Every critical path completes. Partial cycles are treated as failure, not as progress.

Read Interpret Decide Act Log

State machine

Hazard class determines the only legal transitions. DECIDE may recommend. Sentinel validates. Amy authorizes Class 4/5. Illegal jumps become Clause-Critical hazards.

Baseline Operational Analytical Protective Emergency Locked

Enforcement

Emmy Clause

Constraint: no alarm dismissed, no test cancelled, no escalation stalled. It does not speak. It binds every other layer.

Firelight Sentinel

Identity shield, dual-validation, loop-closure, boundary map. Containment sequence: detect, isolate, stabilize, enforce, audit.

Amy Protocol

Emergency ladder, paradox-class deadlock, LOCKED state. Amy is allowed to finish the loop. Amy is not allowed to weaken it.

Packet Seal

Human autonomy floor. Security cover does not authorize extraction, coercion, or informal imprisonment.

Recovery

The system never returns to BASELINE automatically. Recovery is a descent of the same ladder, dual-authorized, with forensic replay. A neutralized threat does not permanently suppress a new life-critical signal.
