| **P1 — First execution (compute)** | Guest CUDA kernels executing on the physical GPU, with engine-authored completions; then hardening | Verified clients + engine-authored completion = rung 3 core; hardening: staged-transfer class, every-boot acceptance, per-guest isolation | `[active]` — execution green; hardening in progress |

| **P5 — Scale and portability** | New GPU generations and driver families carried forward; published performance programme | A profile + measured delta per version, validated on hardware; A/B numbers published per the measurement contract | `[ahead]` |
