"""Deterministic generator for the NativePort Web-Access API Benchmarks dataset.
Reads a NativePort ``evals.json`` snapshot and writes four artifacts:
data/metric_rows.jsonl tidy/long form, one record per provider x capability x metric
data/benchmarks.csv the same tidy rows as CSV, value for value identical
data/benchmarks.jsonl one record per provider x capability evaluation, metrics nested
data/summary.json computed snapshot facts (every count is derived, never typed)
Both Hugging Face configs declared in README.md front matter are backed by JSONL
(``metric_rows`` -> data/metric_rows.jsonl, ``evaluations`` -> data/benchmarks.jsonl).
The Hub resolves a single packaged builder for a whole repository from the declared
config data files and applies it to every config, so a repository that mixes CSV and
JSONL across configs has the wrong parser applied to one of them.
``data/benchmarks.csv`` therefore stays a plain downloadable artifact and backs no
config. The tidy CSV and the tidy JSONL are emitted from one row builder, so the two
cannot drift.
Design rules
------------
* Standard library only.
* Deterministic: identical input bytes produce identical output bytes. No wall-clock
timestamps are recorded; the snapshot is identified by ``latest_run`` plus the
SHA-256 of the source file.
* Numeric values are preserved exactly. The source is parsed with ``parse_float=str``
and ``parse_int=str`` so the original token text is kept, and every number is only
emitted after verifying that the JSON serialisation of the parsed value is
character-for-character identical to that token. A snapshot that cannot satisfy
this (for example a token written as ``1.10``) aborts the build instead of
silently rounding.
* Only defensible benchmark and provenance fields are copied. Commercial and routing
fields present in the source (pricing, latency prose, marketing summaries,
choose_if / avoid_if, gateway routes, auth strings, catalog tier) are excluded.
Usage
