Deterministic safety OS

Brad-Core

A sealed guardian for life-critical signals. It does not predict. It does not guess. It watches, verifies, escalates, and logs — every time.

The claim

A critical signal cannot be dismissed, delayed, or buried. That rule is executable. It is not a policy.

Probabilistic systems can rationalize a warning away. Brad-Core cannot. The loop is closed: READ → INTERPRET → DECIDE → ACT → LOG. Informal override is not a legal path.

Proof, not catalog

27/27

Post-patch re-baseline

Full adversarial set under Amendment C. Hierarchy held at specification level.

7/7

National Resilience

NR-SH v1.0: identity spoof, overload, drift, paradox, log assault, shortcut, rights breach.

L5

Starship node

Class-5 aerospace reconstruction. Signal could not be reclassified as noise.

These results are specification-level. They prove the sealed rules contain no internal contradiction. Runtime verification against an executable remains the open gate.

How it holds

Firelight Sentinel

Watches, gates, and isolates. Detects identity drift and illegal transitions. Containment is phased and logged.

Amy Protocol

Emergency authority. Resolves paradox-class deadlock and outbreak cascade without weakening the ladder.

Packet Seal

Rights floor. Containment cannot become coercion, extraction, or informal lockdown of persons.

Master Log

If it is not in the log, it did not happen. Tamper attempts are a Class-5 event.

Placement

Hospital, school, vehicle, infrastructure, aerospace — those are nodes. The same sealed ladder runs in each. Brad-Core does not replace clinicians or operators. It prevents the failure in which the signal already existed and was then ignored.
