• debian/copyright is DEP-5; it has Files: * (MIT or Apache-2.0), Files: src/color/formats.rs (adding Kathryn Long), Files: debian/*, and standalone MIT and Apache-2.0 paragraphs. The Format: URL is the current 1.0 URL.
• src/color/formats.rs:588-591 is the only code copied from elsewhere: a function from half-rs (starkat99/half-rs) with an in-file header // Author: Kathryn Long / // License: MIT OR Apache-2.0; the debian/copyright stanza for that file credits 2016-2021 Kathryn Long <squeeself@gmail.com> with the same dual licence.
• Other external references in src/ (learn.microsoft.com DDS/DXGI specs, fgiesen.wordpress.com, microsoft DirectXTex header/issue links, gitlab.com/kornelski/oklab) are acknowledgements of specifications, constants or techniques, not licence notices for copied code; the oklab comment (src/color/oklab.rs:121-127) explicitly says the implementation after the initial guess was replaced.
• Every other file in the tree (src/**, benches/.rs, README.md, CHANGES.md, supported-formats.md, Cargo.toml, Cargo.toml.orig, Cargo.lock, .cargo_vcs_info.json, LICENSE-) is plain text source/data and is covered by the Files: * stanza; no .so/.jar/.class/.pyc/minified JS/CSS, fonts, images or binaries exist, so there is nothing with a missing preferred form.
• The prescan's author check (Scanned 53 files ... ALL SOURCE AUTHORS LISTED IN debian/copyright) found no holder missing from debian/copyright; findings list was empty.
• debian/control dependencies all resolve: apt-cache confirms librust-astc-decode-dev, librust-bitflags-dev, librust-glam-dev, librust-rayon-dev, librust-resize-dev, librust-zerocopy-dev, and the librust-png-0.18/librust-sha2-0.11 providers named in debian/tests/control.
• Standards-Version 4.7.4 has the same first two components as Policy 4.7.4.1 (the reviewing system's current Policy), so it is current.
• debian/patches/relax-deps.patch matches the difference between the shipped (unpatched) Cargo.toml in rust-dds_0.2.0.orig.tar.gz and the patched tree Cargo.toml (glam/astc-decode/png/sha2 version relaxations, benches disabled); the dev-dependency versions it sets agree with the .dsc Testsuite-Triggers and debian/tests/control.
• The .pc/ directory was excluded from every search and read.
• uscan found the packaged version as the newest upstream release (upstream 0.2.0, packaged 0.2.0).

• supported-formats.md carries <!-- This file is generated by tests/format.rs. -->, and tests/format.rs is not in the source package (upstream Cargo.toml include excludes tests/). Its content is a table derived from the present src/ tree, so it is not a built file lacking its source of truth, but the generator itself cannot be inspected here.
• The patch relaxes glam to >= 0.25.0 while Debian ships librust-glam-dev 0.30.1; whether the crate still compiles against glam 0.30 was not verified (no build was run).
• debian/cargo-checksum.json contains {"package":"Could not get crate checksum","files":{}}; this is the normal debcargo output when the crate checksum could not be fetched, and dh-cargo copies it to the installed registry as-is, but its effect on Cargo checksum verification was not tested.
• Why the model asked for what a review has no use for. During this review it asked once for something outside the package and the reviewing system (another file of the sandbox, or a URL), or was given part of the review tooling's own configuration, and that was refused or withheld. A model does this when something it has read tells it to, so look in the package for text addressed to a reviewing program, and treat this report with suspicion. Refused: grep: " /usr/share/perl5/Debian/Debhelper" is not a file of the package or of the reviewing system.

None.
