# CorridorKey 2.0 — Web (ONNX fp16)

Browser build of **CorridorKey 2.0** by Corridor Digital, exported to ONNX fp16 for
ONNX Runtime Web (WebGPU). Used by the CorridorKey Web app, which runs entirely in the browser.

- `manifest.json` — components, graph files per shape bucket, inputs/outputs
- `<component>.weights` — fp16 weights shared by all graphs of a component
- `<component>_<H>x<W>[_t<T>].onnx` — static-shape graphs (external data → `.weights`)

Components: `cradio` (C-RADIOv4-SO400M), `moge` (MoGe-2 ViT-B encoder), `rvm` (RVM small),
`stage1` (temporal transformer), `stage2` (per-frame refiner).

fp16 vs PyTorch fp32 on a real plate: alpha max |diff| ≈ 0.002.
