• Read every file under debian/: control, rules, changelog, copyright, copyright.debcargo.hint, cargo-checksum.json, debcargo.toml, source/format, patches/series, both patches, tests/control, upstream/metadata (debian/watch deliberately not reviewed).
• Full upstream inventory built: .cargo_vcs_info.json, Cargo.lock, Cargo.toml, Cargo.toml.orig, CHANGELOG.md, build.rs, src/{binary,error,lib,parse,test}.rs. No LICENSE/COPYING/NOTICE/AUTHORS file, no fonts/images/binaries, no vendored or generated third-party code. .pc/ excluded throughout.
• Grepped the whole tree for copyright/licence/non-free wording (Copyright, (C), ©, SPDX-License-Identifier, Licensed under, Permission is hereby granted, GPL/LGPL/MPL/Apache/CC, public domain, All rights reserved, non-commercial, no-derivative, redistribut*): the only hits are in debian/copyright and debian/copyright.debcargo.hint.
• Sampled rather than read exhaustively: heads of the .rs files read and the rest searched (the 3375-line Cargo.lock was sampled, not read in full).
• Compared the unpacked tree with rust-system-deps-meta_9.0.0.orig.tar.gz: the tarball's Cargo.toml has attohttpc 0.29, cargo_metadata 0.20, lzma-rust2 0.16, zip 2.4 and the junction/inno/pkg-extractor targets, so both patches are applied as expected and debian/* adds no files to the upstream tree; Cargo.lock is upstream's, not added by Debian.
• Checked every librust-* name in Build-Depends-Arch and Depends with apt-cache: all exist (as virtual packages provided by librust-*-dev) and satisfy the stated ranges; dh-sequence-cargo is supplied by dh-cargo (Provides).
• Policy 12.5, 12.5.1, the copyright-format 1.0 document and the autopkgtest control-file specification read from the reviewing system to check the copyright file and the test stanzas.
• uscan found the packaged version as the newest upstream release (upstream 9.0.0, packaged 9.0.0).

• The copyright years in the Files: * stanza (2021-2026 Guillaume Desmottes, 2016-2019 Josh Triplett). No file carries a year, and debian/copyright.debcargo.hint says the years were taken from the upstream Git history; upstream's repository is not in the tarball, so they cannot be verified from here.
• Whether the optional-feature code (src/binary.rs, the zip/gz/xz paths) still compiles against Debian's newer crates that relax-deps.patch allows (attohttpc 0.31, which 8, zip 5, lzma-rust2 0.19). dh_auto_build builds only the default feature set (empty), so the Debian build never compiles those paths; a build with --all-features would show it. The attohttpc::Error conversion and zip::ZipArchive::new/extract use look version-agnostic, but the crates' sources are not on this system to check.
• Whether autopkgtest recognises the Restrictions: flaky used in all nine stanzas of debian/tests/control. The autopkgtest document shipped with debian-policy lists only rw-build-tree, breaks-testbed, needs-root, build-needed, allow-stderr, isolation-container, isolation-machine and needs-recommends, and says unknown restrictions cause the stanza to be skipped; autopkgtest itself is not installed here, and flaky is what debcargo generates. If it were unknown, no test would run at all.
• Whether debcargo normally writes real checksums into debian/cargo-checksum.json: debcargo is not installed on the reviewing system, so the 'Could not get crate checksum' value could not be compared with the tool's output when it can reach crates.io.
• 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/cargo" is not a file of the package or of the reviewing system.

None.
