Physics-grounded deterministic verification layer for AI agents, robots, vehicles, drones — and the SDKs that drive them. Every claim ships with an on-disk artifact; every aggregate recomputes from open metric files.
Four layers, closing state 2026-10-09 — full ledger with verbatim metrics, audit logs, closing marks and SHA-256 manifest: phm-evidence-ledger
| Layer | Count | Unit | Headline result |
|---|---|---|---|
| Physics-engine gate (Master 2B) | 1,900,000,000 +100M baseline | program executions | FP=0 / FN=0 observed, 10 classes, REACHED_2B mark |
| Verifier validation scenes | 1,000,000,000 | scene executions | per-class n/ok recorded verbatim |
| Robotics stream gate | 1,000,086,001 | data frames | collision class: 43,440,642/43,482,000 actively BLOCKed |
| SCL fuzzing | 1,000,000,000 | program executions | no crash observed; 3,226,364,783 rule hits; 2.41 ms/program |
Caliber: three layers count executions, one counts frames — mixed by design, stated per line. Zero-valued results mean "not observed in this test set", not absolute guarantees.
Deterministic, operator-declared, pre-execution adjudication with an audit ledger — gate-first (benign FP=0), evidence-first (every number recomputable), closed engines with open metrics.
Scripts are closed-source core assets; metrics, logs, and gates are open.
