• Read all of debian/: changelog, control, copyright, rules, gbp.conf, salsa-ci.yml, watch (not judged), source/format (3.0 (quilt)), upstream/metadata; there are no patches, no maintainer scripts, no debian/tests/control (Testsuite: autopkgtest-pkg-go, generated by autodep8) and no install/links/docs files.
• Upstream inventory: 24 files outside .pc/ and debian/ — LICENSE, README.md, go.mod, go.sum, .gitignore, .github/workflows/test.yaml, log/log.go, xfs/{ag,cache,const,inode,sb,xfs}.go, xfs/{inode,sb,timestamp,xfs}_test.go, xfs/utils/{utils,utils_test}.go, xfs/testdata/{image.xfs,image40.xfs,os-release}.
• Grep for Copyright/(C)/©/SPDX-License-Identifier/Licensed under/Permission is hereby granted/GNU GPL/LGPL/Apache/Mozilla/public domain/All rights reserved/MIT/BSD/ISC/CC-BY/MPL over the whole tree (gitignore: false, .pc excluded) matches only LICENSE (the Apache-2.0 text, appendix placeholder Copyright {yyyy} {name of copyright owner}) and debian/copyright. No file carries its own notice, so Files: * and the copyright Comment ('Upstream has no copyright notice ... The holders are the authors of the commits') are accurate.
• debian/copyright is DEP-5 with the canonical Format URL; Files: * covers all upstream files and debian/* the packaging; the six Copyright lines correspond to the tree's commit authors; License: Apache-2.0 carries the Apache boilerplate and the pointer to /usr/share/common-licenses/Apache-2.0 (the complete text is there).
• Files-Excluded: docs — no docs/ directory is in the unpacked tree or in the orig tarball, so the repack exclusion is consistent; the Comment explains it (a DBLaTeX-built PDF whose .tex source is not shipped), i.e. a DFSG #2-justified removal of a built file.
• xfs/testdata/image.xfs (20 MB) and xfs/testdata/image40.xfs (40 MB) are XFS filesystem images used as test fixtures, not built programs; README.md 'How to create test data' gives the mkfs.xfs/genimage recipe that produced them, so their preferred form for modification is documented in the package. I did not open them (binary).
• xfs/testdata/os-release is a copy of CentOS Linux 8's /etc/os-release used as the expected output of reading etc/os-release out of the test image (xfs/xfs_test.go:250-252) — short factual configuration with no copyrightable content, acknowledged in the copyright Comment, and it is the os-release embedded in the test images too.
• No vendored third-party Go code: go.mod requires only go.uber.org/zap (with atomic, multierr) and golang.org/x/xerrors, which Debian provides and which are in Build-Depends/Depends; xfs/*.go are hand-written (no copied CRC/UTF-8 tables, no kernel/xfsprogs licence text).
• dh-go 1.69 in unstable ships both the golang buildsystem (/usr/share/perl5/Debian/Debhelper/Buildsystem/golang.pm) and the golang sequence addon (/usr/share/perl5/Debian/Debhelper/Sequence/golang.pm), so dh $@ --builddirectory=debian/_build --buildsystem=golang --with=golang is valid; Build-Depends: dh-go is enough, and golang-any is the right compiler dependency.
• dpkg-build-api (= 1) is how dpkg-build-api(7) says the build API level is declared ('The declaration of this API level is done through build-dependencies'), and apt-cache shows dpkg-dev 1.23.11 Provides: dpkg-build-api (= 1) — not a nonexistent dependency.
• autodep8's go template (/usr/share/autodep8/support/go/generate) runs dh_golang_autopkgtest, which rebuilds from the installed /usr/share/gocode/src tree, so the testdata installation is deliberate and the package's own autopkgtest is covered.
• Standards-Version 4.7.4 against Policy 4.7.4.1 (policy tool): first two components equal, so current; the changelog closes the ITP (#1152505), the version 0.1.8+git20260422.d21e5e4+ds-1 and the Friday 30 Oct 2026 date are consistent with the April 2026 snapshot.
• uscan found upstream releases with debian/watch; a newer upstream version is available (upstream 0.1.8+git20261019.ccf49f5, packaged 0.1.8+git20260422.d21e5e4+ds), 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 copyright holder list is derived from upstream commit authorship (as debian/copyright's Comment says); I could not consult upstream history or any NOTICE/contributor list (no network), so whether any contributor or an employer (e.g. a work-for-hire entity) is missing cannot be checked from the source alone.
• I did not open the two .xfs images (binary) and so did not inspect their contents beyond what README.md, debian/copyright's Comment and the tests state; and I did not read xfs/inode.go (30 KB) or the whole of inode_test.go line by line, only grepped them for licence and provenance text.

None.
