Canonical medium JAXJS release

This composed release lane assembles canonical FP16 PP-DocLayoutV3, its explicit FP32 rollback, the streaming OCR recognizer, and the three all-JAXJS MinerU table artifacts before it installs model-sets/medium.json. The historical FP32 startup evidence remains relevant to the rollback artifact, while the FP16 browser result and CLI/WASM memory boundary are recorded separately.

The FP32 model remains an explicit non-default verification and rollback profile. Canonical medium selects FP16 PP-DocLayoutV3, the streaming OCR recognizer, and the all-JAXJS table trio; it never falls back to FP32 or ONNX implicitly. The layout, streaming OCR, and table descriptors all pin immutable artifact revision 3ebf4493fe544793ad72ece74cf4777b281460d6.

Reproduce

From the OCR JS workspace with the pinned Paddle source available:

pnpm jaxjs:convert-pp-doclayout-v3
pnpm jaxjs:convert-pp-doclayout-v3-fp16
pnpm --filter @ocr-js/pipeline-runner verify:pp-doclayout-v3
pnpm jaxjs:stage-medium-release -- /path/to/pj-ocr-jaxjs-medium

No WebGPU execution is required for conversion or the frozen WASM oracle checks.
