## Unreleased

### Added

- `python -m benchmarks.legs.browser_steps`: offline step-level scoring of browser decision backends on
[myjev-browser-decisions](https://huggingface.co/datasets/Mlchemist/myjev-browser-decisions) (pinned revision,
hash-checked at download, never vendored; CC BY-NC-SA 4.0). `predict` sends each step through `DecisionModel`
(any text backend), one request at a time, no retries, failures scored wrong; `score` reports operation and
element accuracy, step success, Brier/ECE and latency with denominators, on the full split and the Jev-answered
subset; `thresholds` turns a calibration run into a deferral threshold table. `--shape dataset` re-sends
jev-ultrafast's body unchanged, `--shape ours` swaps in our operation text and rules. Only a random floor is
reported so far. See [docs/results/browser-steps](docs/results/browser-steps/README.md) (#109).

Browser decision backends are scored step by step, offline, on myjev-browser-decisions
