"""Canonical longform parser (#27) — pytest side of the cross-impl golden corpus.
|
||
|
||
This suite and ``electron/src/shared/test/longformParser.test.js`` load the SAME JSON
|
||
(`tests/fixtures/longform_parser_cases.json`) and assert both impls produce it
|
||
byte-for-byte. A divergence cannot pass both suites — the side that drifts fails
|
||
its own assertion against the shared truth.
