# Revision B validation

Final evidence is in **release-*.log**, **main-native-drc.json**, **flex-native-drc.json**, **release-verify.log**, the native pad exports and manufacturing/rev-b/release-manifest.json. Other logs describe earlier draft layouts and platform investigations; they are retained as evidence and are not revision B acceptance reports.

| Check | Main | Flex |
| --- | --- | --- |
| TypeScript | Pass | Pass |
| Source netlist | Checked | Checked |
| Actionable schematic overlaps | None; remaining global decoupler-grouping heuristic is P3 | None; same P3 advisory |
| Source PCB placement | 0 DRC errors/warnings | 0 DRC errors/warnings |
| tscircuit routed build | Fails reachability precheck P6; native completion used | Pass, 0 Circuit JSON errors |
| Native KiCad copper/holes/connectivity | 0 violations, 0 unconnected | 0 violations, 0 unconnected |
| Source/native correspondence | 190 SMT pad positions and named nets match | 41 SMT pad positions and named nets match |
| Additional contract | Charger pin map, radio supplies, NC pins | Supplies/NC pins, three stiffeners, bend reserve, eight straight top bend traces |

Native copper and source/native checks apply to the frozen native manufacturing files, not the incomplete main tscircuit PCB preview. KiCad's standard ignored-check list is included in its full reports; no custom electrical DRC exclusions were added. Laser coverlay uses a separate artwork layer and its ≥0.5 mm web review is recorded in flex-coverlay-windows.json; copper DRC does not validate the full lamination process.

The main board has local fine-pitch neckdowns below 0.15 mm, checked against its declared 0.10 mm process minimum. Flex remains at least 0.15 mm. Native SVG/PDF-derived copper, ground-plane and flex fabrication previews were visually inspected.

No physical RF, temperature/charge, endurance, optical, fatigue, skin-contact or environmental test has been performed. Follow the assembly/bring-up guide before battery charging or wearable use.
