Decoder profile verd-pillow/1stable
§7 Provenance of this directory
Every image was produced by scripts/make_decoder_corpus.py from closed-form integer arithmetic over the pixel grid — no seeded RNG, no fonts, no floating point. Every digest in manifest.json was computed from the committed bytes by verd.cpnp.canonicalize and verd.hashing.pixel_hash; none was written by hand. --check regenerates the whole tree into a temporary directory and byte-compares, so the claim "these are the bytes that script produces" is itself executable:
If a future encoder emits different bytes for the same drawing, that command fails and the answer is a new release directory — never an in-place regeneration of this one.
