"""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
-----
