"""Generator for tpc/vectors/yardstick_corpus.json (TPC step 2, increment 5).
Expectations are HAND-DERIVED from the synthetic suite and written literally
below; the generator refuses to write the corpus if the module disagrees.
Run: cd tpc && python3 gen_yardstick_corpus.py (Windows: py ...).
Recovered 2026-09-27 (BASE-GEN; record 0.18.0 section 7) from the TIDY 3
archive, tidy3_2026-09-25/gen_yardstick_corpus.py, SHA-256
74edc22c5818f5c8f93f5004b76128e52dd857bbc95ea11289729e891f49eae1, where it
regenerates the archived corpus byte for byte. Changed in the tree: the
writer only (ensure_ascii=False, so a hidden character is written as
itself, as the published corpus carries it; RD-C8-2). No case changed."""
