• All 25 files of the tarball are accounted for: Files: * (BSD-3-clause, "2022, the Dart project authors") covers every file, and the later stanza Files: test/tests/_formatting_test.dart and test/tests/end_to_end/leak_detection_test.dart covers the only two files whose headers say Copyright 2023 The Chromium Authors; no other copyright or licence wording exists in lib/, test/ or the top-level files.
• LICENSE is the Google/Dart BSD-3-clause text, and debian/copyright reproduces it in full in its stand-alone License: BSD-3-clause paragraph, so the permissive notice is retained as the licence requires.
• The prescan's answer (every holder found is named in debian/copyright) matches the tree; the Dart project headers in lib/ and test/ name the same holder as Files: *, and the Chromium headers are the only other holder.
• No binaries, archives, .class/.jar/.so, minified or generated source in the orig tarball (only .dart, .md and .yaml). lib/DEPENDENCIES.md is a layerlens-generated mermaid diagram of the shipped sources, not generated code with a missing input.
• The unpacked tree matches dart-leak-tracker-flutter-testing_3.0.10.orig.tar.gz; the debian tarball contains no debian/patches, so there are no patches to review, and .pc/ is quilt's unpack artifact (it is not in the orig tarball).
• debian/control dependencies mirror pubspec.yaml exactly: flutter (>= 3.18.0), dart-leak-tracker (>= 11.0.1)/(<< 12.0.0), dart-leak-tracker-testing (>= 3.0.1)/(<< 4.0.0), dart-matcher (>= 0.12.16)/(<< 0.13.0), dart-meta (>= 1.8.0), i.e. pubspec's flutter, >=11.0.1 <12.0.0, >=3.0.1 <4.0.0, ^0.12.16, ^1.8.0.
• Every runtime dependency and autopkgtest dependency is satisfiable: apt-cache has flutter 3.47.5, dart-meta 1.19.0, dart-sdk 3.13.4, flutter-tester and flutter-patched-sdk 3.47.5; dart-leak-tracker 11.0.2-1, dart-leak-tracker-testing 3.0.2-1 and dart-matcher 0.12.20-1 are in ftp-master's NEW queue and fall inside the declared ranges, so they are not reportable as missing.
• Build-Depends are satisfiable: debhelper 14.5 in the archive Provides both debhelper-compat (= 14) and dh-sequence-single-binary (apt-cache), and the addon exists at /usr/share/perl5/Debian/Debhelper/Sequence/single_binary.pm.
• debian/install gives lib and pubspec.yaml with the destination usr/share/dart/packages/leak_tracker_flutter_testing/; dh_install(1) installs a directory source under its own name into the destination (plugins usr/share/my-prog -> usr/share/my-prog/plugins/), so the installed layout is .../leak_tracker_flutter_testing/lib/..., which is what the pubspec name and the smoke test expect.
• At compat 14 dh_missing defaults to --fail-missing, but it only scans debian/tmp (default --sourcedir) and exits 0 when that does not exist; dh_install installs into debian/dart-leak-tracker-flutter-testing and nothing creates debian/tmp, so the uninstalled test/, CHANGELOG.md, LICENSE and analysis_options.yaml do not fail the build (checked in dh_missing(1) and /usr/bin/dh_missing).
• debian/rules's override_dh_install only touches directory mtimes after dh_install; ${SOURCE_DATE_EPOCH} is exported by dpkg-buildpackage, so the find/touch cannot fail there.
• Changelog is a well-formed initial release (3.0.10-1, unstable, urgency medium, closes #1152239, date Tue 27 Oct 2026 is consistent); debian/source/format is 3.0 (quilt); Vcs-Git, Vcs-Browser, Homepage and debian/upstream/metadata are present and sane; Standards-Version 4.7.4 matches current Policy 4.7.4.1.
• debian/tests/control names the shipped debian/tests/smoke script, whose POSIX-sh body builds a package_config.json for the installed packages, compiles a small program against the Flutter patched SDK and runs it under flutter_tester, offline, writing only under mktemp -d.
• uscan found the packaged version as the newest upstream release (upstream 3.0.10, packaged 3.0.10).

• The smoke test's hard-coded engine locations (/usr/lib/flutter-engine/linux-x64/flutter_tester and .../flutter_patched_sdk/) and its frontend_server invocation could not be exercised or checked against the package that ships them, because flutter/flutter-engine are not installed on the reviewing system; the paths are plausible for the archive's sky-engine/flutter-tester layout but unverified.
• The APIs the shipped lib/ and the smoke test use from dart-leak-tracker 11.0.2-1 and dart-leak-tracker-testing 3.0.2-1 (for example LeakTesting.collectedLeaksReporter, IgnoredLeaks.isIgnored, withDisposalStackTrace, withIgnoredAll) could not be checked, since those packages are only in the NEW queue and not installable or readable here.
• File modes (executability of debian/rules and debian/tests/smoke) are not visible through the read-only file tools used, so they were assumed to be executable as autopkgtest requires.

None.
