PhotoCraft's `photocraft-psd` crate (crates/psd at storytold/photocraft 63b641b55e54bf8f5c83efd977fdb16a2c255431) as `craft-psd`: the lossless PSD/PSB model, reader, writer and builder, descriptors, the Photoshop resource files that share its primitives (.abr, .asl, .aco, .act, .ase, .grd, .pat, .atn, .csh, .shc) and the Photoshop blocks of a layered TIFF. The crate had no dependency on any other PhotoCraft crate. Code is unchanged apart from the crate name, craft-libs' rustfmt width, comments that named other PhotoCraft crates, issue references (now `photocraft#N`), and the corpus tests' directory (`CRAFT_PSD_CORPUS` or `corpus/` at the workspace root). Tests, proptests, fuzz targets and fixtures move with it. Part of #778, #786.
Synthetic ATN parser fixtures
These seven tiny files are original synthetic test data. The four version-16 files were independently
encoded field by field from the version-16 layout documented in src/atn.rs, without calling
this crate's writer; the three version-12 files (v12-*.atn) encode the version-12 layout documented
there (photocraft#10743). They are licensed MIT OR Apache-2.0 under the repository's licenses. They contain no
user artwork, Photoshop program code or proprietary assets. They are not Photoshop-authored
interoperability oracles.

tests/it/atn_contract.rs checks the independently encoded version-16 bytes and expected public
structures; tests/it/atn_v12.rs checks the
version-12 files. The version-12 files follow the version 12 layout in src/atn.rs, assembled from
the measured grammar in photocraft#10603. Their Idnt reference follows the inferred index-like layout; no
real version 12 identifier reference was available. Saving them produces version 16, so keep them
out of the version-16 byte-identical corpus oracle.
The files also seed the atn fuzz target: cargo fuzz run atn crates/psd/tests/fixtures/atn
(from crates/psd: cargo fuzz run atn tests/fixtures/atn).
A fixture change should explain the changed wire fields and update this table; do not regenerate expectations merely to make a failing parser pass.
