• debian/copyright is DEP-5 with the correct Format: URL, Upstream-Name, Source, Files-Excluded and standalone licence paragraphs; the Files: * BSD-2-Clause text is verbatim the upstream LICENSE, and the Apache-2 paragraph refers to /usr/share/common-licenses/Apache-2.0.
• Licence evidence collected by grepping the whole tree for SPDX tags, Copyright/(C)/©, BSD/MIT/Apache/GNU/WTFPL/All rights reserved/public domain/non-commercial wording: the only hits are LICENSE, NOTICE, LICENSES/, THIRD_PARTY_LICENSES.md and per-file doc comments saying "MIT OR Apache-2.0" (rars ports) or "BSD-2-Clause". No non-free or no-modification wording anywhere.
• The rars-derived files listed in the Apache-2 stanza each state MIT OR Apache-2.0 and the upstream revision (c08a17b) in their module headers (e.g. crates/rar/src/crypto/rar50.rs:1-5, crates/rar/src/codec/legacy/rar15.rs:1-13), so restricting them to Apache-2.0 is a permitted choice; Apache-2.0 and BSD-2-Clause combine in the one binary without conflict.
• crates/rar/src/codec/mod.rs:5-9 and crates/rar/src/codec/modern/lzss_huff/mod.rs:5-8 credit libarchive's archive_read_support_format_rar5.c (Grzegorz Antoniak, BSD-2-Clause) as the analysis basis rather than as copied code, and debian/copyright's Comment records this; the project's own holders stay correct for those files.
• All 78 archives/compressed files and the 4 unrecognised binary files the scan listed are test inputs under crates/rar/tests/fixtures/rar40/** and rar50/**: RAR archives, multi-volume sets (.rar/.r00/.r01/...), .rev recovery volumes and tail-match-362.bin. They are read by the tests, not built; the rar40/* ones fall under the Apache-2.0 stanza and rar50 under Files: *, and crates/rar/tests/fixtures/rar50/README.md documents each of the latter (including that winrar5_multiple_files.rar comes from libarchive).
• crates/rar/tests/fixtures/rar40/rarvm/solid_e8_filter_payload.exe is the expected payload of the solid-filter regression test (crates/rar/tests/rar_vm_filters.rs:46-47,69-74) and is covered by debian/source/lintian-overrides, which states it is a manually constructed file. It was not opened (binary); it is stored in solid_e8_filter_member_offset.rar at 295 bytes for 5884 bytes, a ratio only repetitive synthetic data reaches, and its companion solid_e8_filter_lead.txt is likewise typed filler.
• Files-Excluded was checked against the tree: crates/rar/tests/fixtures/rar13, .../fixtures/x86, .../rarvm/filter_bsdcat_exe.rar, .../rarvm/vm_encoded_u32_filter.rar, crates/rar-napi, crates/rar/tests/rar13_read.rs, crates/rar-cli/tests/winrar_interop/rar13.rs and .github are all absent, and debian/patches/exclude-fixtures.patch removes or ignores the tests that used them (the ntoskrnl_dense_prefix.bin test is #[ignore]d and reads its path with std::fs::read, so it still compiles).
• docs/FORMAT_RAR5_RAR7.html is the project's own HTML documentation, covered by Files: *; it loads Tailwind CSS and Mermaid from CDNs at view time (<script src="https://cdn.tailwindcss.com">) but ships no JavaScript, so no third-party code is embedded and no preferred form is missing.
• Packaging read in full: control, rules, both .docs, unrar-rs.1, unrar-rs.alternatives, unrar-rs.manpages, changelog, source/format, source/lintian-overrides, salsa-ci.yml, patches/series and every patch. Patch headers carry From/Date/Subject (two also Origin), the 32-bit patches fix real usize overflows, and drop-rar-napi.patch/drop-windows-sys.patch explain why unpackaged crates are removed.
• The alternatives stanza uses the dh_installdeb format correctly and takes over /usr/bin/unrar with its man page; unrar in the archive ships unrar-nonfree, and unrar-free declares Conflicts: unrar-nonfree (<< 1:3.7.8-1), so the link is the established interface and coexists with those packages.
• dh-rust 0.1.4 (provider of dh-sequence-rust) was read at /usr/share/perl5/Debian/Debhelper/Buildsystem/rust.pm: X-Cargo-Crates: rar-cli resolves to the rar and unrar binaries, cargo install puts both under debian/rar-rs, so the mv in execute_after_dh_auto_install is what gives unrar-rs its binary; unrar-rs needs no field of its own because dh-rust only falls back per crate when no package has been tied yet.
• dh-rust-built-using writes Built-Using/Statically-Built-Using only into the substvars of the package the crate is tied to (rar-rs), so the moved unrar-rs binary has no such field; Policy 7.8 requires Built-Using only where the licence of the incorporated source requires it, and every Rust crate here is permissive, so this is not a fault.
• crates/rar-cli/src/common.rs parses -dh, -ver, -vp, -cfg-, -sc, -om, -ow, -kb, -ol and ~/.rarrc, so debian/unrar-rs.1 describes options the tool actually has.
• uscan found upstream releases with debian/watch; a newer upstream version is available (upstream 0.14.0, packaged 0.12.0+dfsg), which is not a fault of the package.
• Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (Apache-2.0).

• The fixtures taken from the rars test corpus could not be traced to their origin: the package's own THIRD_PARTY_LICENSES.md says of crates/rar/tests/fixtures/rar40/ that "their own redistribution review is still outstanding" and NOTICE says they "remain subject to the terms of that corpus", while debian/copyright attributes the whole directory to Gareth Davidson under Apache-2.0. Without network access to bitplane/rars at revision c08a17b I cannot check whether every archive in that corpus originates with rars or with a third party.
• The rars licensing history recorded in the Apache-2.0 stanza's Comment (a COPYING that read "WTFPL with 1 extra clause" for a few weeks, an MIT option later removed) could not be checked against the upstream repository; it rests on the maintainer's assertion.
• crates/rar/tests/fixtures/rar40/rarvm/solid_e8_filter_payload.exe was not inspected (binary). If it were a compiled Windows program rather than the synthetic payload the lintian override describes, its source would be missing from the package.
• debian/copyright attributes that same .exe to Gareth Davidson under the rar40/* Apache-2.0 stanza, while debian/source/lintian-overrides calls it manually constructed; one of the two attributions is presumably wrong (harmless, both permissive).

None.
