• Read every file in debian/ in full: control, rules, changelog, copyright, gbp.conf, lrc.config, README.source, salsa-ci.yml, source/format, source/lintian-overrides, upstream/metadata, watch was left alone; there is no debian/patches, debian/tests, debian/install or debian/*.docs.
• debian/copyright is DEP-5: Files: * Facebook, Inc. and its affiliates, Apache-2.0; Files: debian/* 2026 Juan Manuel Méndez Rey, Apache-2.0; Files: vulndb/sqlutil/b64schema/lint.go Apache-2.0 and BSD-3-clause with the standalone Apache-2.0 and BSD-3-clause texts, the latter reproducing the Go Authors' 2013 notice.
• Whole-tree grep for Copyright, (C), ©, SPDX-License-Identifier, Licensed under, GNU/Apache/MPL/MIT/CC/BSD wording, All rights reserved and non-free terms found only the Facebook per-file header and, at vulndb/sqlutil/b64schema/lint.go:15, Copyright (c) 2013 The Go Authors. All rights reserved.; that file's own stanza covers it, and the prescan's author check (no files listed, every holder named) agrees with the grep.
• Files-Excluded: debian matches reality: the orig tarball lists only nvdtools-0.1.5/ with no debian/ entry, and the unpacked tree has no upstream debian files left over; nothing else is excluded by the pattern.
• No binary or non-source assets: a glob for png/jpg/gif/pdf/jar/class/so/dll/exe/pyc/woff/ttf/zip/gz/bin found nothing, and the LICENSE is stock Apache-2.0 (appendix placeholder unfilled, hence the holder taken from the per-file headers as the copyright Comment says).
• Generated code is plain, readable Go and outside the shipped packages: cvefeed/nvd/schema/schema.go (auto-generated types) and providers/idefense/schema/schema.go (generated from the schema file and script.sed, both present); neither directory is installed in the binary, so no preferred-form issue arises.
• Shipped packages (wfn, cvss2, cvss3, cpedict, rpm) import only the standard library, github.com/facebookincubator/nvdtools/wfn and testify from _test.go files; their tests use embedded XML/JSON strings, not network fetches.
• No package main outside the excluded trees: all 41 hits are under cmd/ or vulndb/sqlutil/b64schema, so the Architecture: all -dev package installs no binaries; DH_GOLANG_EXCLUDES applies to build and install (DH_GOLANG_EXCLUDES_ALL defaults to true from compat 12).
• The exclusion justification holds: github.com/facebookincubator/flog and github.com/dgrijalva/jwt-go/v4 are not in the archive (apt-cache: no such binary package in unstable or in NEW), and cmd/ and vulndb/ do import flog.
• Dependencies resolve: apt-cache shows dh-go 1.69 (provides the golang debhelper addon and buildsystem, Conflicts dh-golang, so the lintian override is right), dpkg-build-api provided by dpkg-dev 1.23.11 (= 0 and = 1), golang-any and golang-github-stretchr-testify-dev; Standards-Version 4.7.4 against Policy 4.7.4.1 is current; changelog is 0.1.5+ds-1, unstable, initial release closing #1148638.
• Testsuite: autopkgtest-pkg-go fits autodep8's go template (detected via golang-any in Build-Depends), which runs dh_golang_autopkgtest with the package and @builddeps@ installed.
• Files-Excluded removes only upstream's own debian/ directory, which the Debian packaging replaces anyway, so that alone calls for no repack suffix.
• uscan found the packaged version as the newest upstream release (upstream 0.1.5, packaged 0.1.5+ds).
• Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (Apache-2.0).

• providers/rustsec/rustsec_test.go:92 notes that its sampleAdvisory string was copied from https://github.com/RustSec/advisory-db; that project's licence is not in this tree and I could not check it. The copied part is a short advisory template in a test file in a directory that is not shipped in the binary.
• No build or test was run, so the exclude list and the golang buildsystem's go test step were not exercised.

None.
