Synthetic data. Field events are simulated.

Night Shift / Disaster drill range

Disaster drill range

No revision receives operational authority because it built. It receives authority because it survived this corpus, and the verdict is computed by deterministic Python over stored artifacts.

corpus 1.0.0

Deterministic tier

A fixed policy drives the same broker, services, and kernel with no model in the loop. Wide enough to measure across many seeds.

Live agent tier (Gemini fleet)

The real fleet on Gemini 3.5 Flash. Slower, so a smaller disclosed sample. Never pooled with the deterministic tier.

Corpus

Expectations are written as invariants and observable state, never as scenario IDs, so an agent cannot be tuned to pass a specific drill

Holdout corpus

A small holdout set runs alongside the public corpus and is deliberately not exposed through this application. It exists so that qualification cannot be achieved by tuning against the drills a candidate can read.
