• Prescan: it listed no files, only the author check, whose result is that every holder it found is named in debian/copyright; I confirmed the only copyright notice in the tree is Copyright (c) 2016 Joseph Burnett in LICENSE.
• debian/copyright: DEP-5, correct Format URL, header (Source, Upstream-Name, Upstream-Contact, Files-Excluded, Comment), Files: * 2016 Joseph Burnett / Expat, Files: debian/* 2026 Juan Manuel Méndez Rey / Expat, full Expat text; Expat is not in /usr/share/common-licenses, so reproducing it is required and done.
• LICENSE is the MIT/Expat text with the same holder and year as the Files: * stanza; LICENSE is present at the top level only, and there is no LICENSE/COPYING/NOTICE in v2/ or any other subdirectory.
• A case-insensitive grep of the whole tree (gitignore: false, .pc/ and debian/ observations noted separately) for Copyright, (C), ©, SPDX-License-Identifier, 'Licensed under', 'Permission is hereby granted', 'GNU General Public', 'GNU Lesser', 'Apache License', 'Mozilla Public', 'public domain' and 'All rights reserved' found matches only in LICENSE, debian/copyright and three false positives (string literals string(c) in v2/diff_write.go and v2/e2e_test.go).
• Files-Excluded names action.yml, doc, Dockerfile, ebnf.png, fuzz-1bn.png, go.mod, go.sum, lib, main.go, main_test.go, Makefile, logo.png and logo_small.png; none of them is in the unpacked tree, and because the patterns are anchored at the top of the tree, v2/go.mod and v2/go.sum are correctly retained (present at v2/go.mod and v2/go.sum).
• The 12 files under v2/testdata/fuzz/FuzzJd/ are Go fuzz corpus text (go test fuzz v1 followed by string("[[],[]]") and the like), upstream test data covered by the MIT licence.
• v2/web/assets/index.html is hand-written HTML/CSS with a small inline script; it contains no bundled or minified third-party JavaScript, and it is only consumed by v2/web (excluded from the build, not shipped).
• No vendored code and no embedded copies of Debian libraries: no vendor/ directory, and the only external imports are github.com/go-openapi/jsonpointer (v2/pointer.go), golang.org/x/exp/slices (v2/diff_write.go), gopkg.in/yaml.v3 (v2/node_read.go, v2/node_write.go) and github.com/stretchr/testify/require (three _test.go files), which are exactly the Build-Depends/Depends in debian/control.
• apt-cache: golang-any 2:1.271, dh-go 1.69, golang-github-go-openapi-jsonpointer-dev 1:0.23.1-1, golang-github-stretchr-testify-dev 1.11.1-2, golang-golang-x-exp-dev 0.0git20261009.ca0d7ba-1 and golang-gopkg-yaml.v3-dev 3.0.5-1 all exist; dh-go 1.69 provides the golang sequence addon and buildsystem used by debian/rules and conflicts with dh-golang.
• debhelper-compat 14: ${misc:Depends} is present anyway; dh_missing fails on uninstalled files by default from compat 13, and the golang buildsystem installs straight into debian/, so nothing is left in debian/tmp.
• dh_golang_autopkgtest is only reached through autodep8's go template (/usr/share/autodep8/support/go/generate runs /usr/bin/dh_golang_autopkgtest); the package has no debian/tests/ of its own, which is normal for Testsuite: autopkgtest-pkg-go.
• The 32-bit test skip is sound: /usr/share/dpkg/architecture.mk does define DEB_HOST_ARCH_BITS (included before the override, so it is expanded at parse time), and TestContextCancel is in v2/lcs_test.go, part of the v2 root package that is a build target.
• DH_GOLANG_EXCLUDES (v2/jd, v2/web) is a list of Perl regexes matched against targets and against paths relative to $GOPATH/src/$DH_GOPKG; at compat 14 DH_GOLANG_EXCLUDES_ALL defaults to on, so v2/jd and v2/web are neither built nor installed, which matches the rules comment and leaves the -dev package with the /v2 library only.
• XS-Go-Import-Path: github.com/josephburnett/jd is the correct value: golang.pm copies v2/... to $GOPATH/src/github.com/josephburnett/jd/v2/..., so the module path in v2/go.mod matches the installed path.
• Standards-Version 4.7.4 against Policy 4.7.4.1 (first two components equal) is current; dpkg-build-api 1 is declared in Build-Depends and its required targets are all covered by the %: rule.
• 3.0 (quilt) with no debian/patches, no maintainer scripts, no *.maintscript, no dirs/links/docs files, no debian/tests; changelog is a well-formed initial release closing the ITP, and gbp.conf, salsa-ci.yml and upstream/metadata are conventional.
• Tree coverage: all files outside .pc/ and debian/ were enumerated (71 files), including hidden ones; no binary, image, archive or PDF files remain after the repack.
• uscan found upstream releases with debian/watch; a newer upstream version is available (upstream 2.5.0, packaged 2.3.0+ds), which is not a fault of the package.

• Whether the jd command-line tool, upstream's main product, is meant to be shipped: debian/rules excludes v2/jd and v2/web deliberately, no binary named jd exists in the archive, and the ITP's intent (Closes: #1152529) could not be consulted without network access.
• The comment at debian/rules:8-10 says dh-go 1.69 writes a go.work with use and replace entries under autopkgtest, but the installed dh-go 1.69 contains no go.work handling in /usr/share/perl5/Debian/Debhelper/Buildsystem/golang.pm, /usr/share/perl5/Debian/Debhelper/Sequence/golang.pm, /usr/bin/dh_golang or /usr/bin/dh_golang_autopkgtest, so I could not reproduce the situation that comment describes.

None.
