## Performance

## Browser (LiteRT.js)

Model-level sweep results — measured behavior of this exact `.tflite` in the browser, only meaningful together with the environment that produced it. Full records (failure class, error evidence, sweep config): `data/sweep/2.5.3/2026-08-11/qwen3-reranker-0.6b.json`.

## Device runs (NPU / LiteRT-LM)

Model-level on-device results — measured behavior of this exact artifact on the recorded device, only meaningful together with that environment. Throughput is conditional on the measured prompt length (Prompt (tokens); '-' = the source stated none): rows differing only there are different measurements, not re-runs. Full records (failure classes, log evidence): `data/device_runs/2.2.0/2026-08-27/qwen3-reranker-0.6b__galaxy-s26.json`.

## Pitfalls

- Token embedding lookup is host-side from the shipped embeddings_fp16.bin table; the graph consumes inputs_embeds [1,256,1024] and emits a baked 2-logit ('no'/'yes') head — host softmax gives P(yes) (zoo README L1852-1860).
