Tier-1 Validation Matrix

Each cell shows its committed status (gated by the Tier-1 ratchet on every change; the full sim suite runs nightly) and links the CI run that recorded it when one is available.

Confidence tier: ✅ means sim-consistent — the check passed against the simulator's peripheral models on real firmware. Silicon-anchored verification (hardware-in-the-loop capture replay) is a separate tier that arrives with the HIL workstream; no cell currently claims it.

Legend: ✅ passed · 🟡 partial · ⛔ modeled but failing · 🚧 not modeled yet · · no check written. Every column here is a subsystem that exists in silicon on all listed parts, so 🚧 is an honest model gap, not an "N/A".
