• Read debian/copyright in full: three Files stanzas (*, the four Chromium files, debian/*), one stand-alone License paragraph with the complete BSD-3-clause text.
• Tree inventory: 55 files outside .pc/ and debian/, all text (.dart, .md, .yaml). 42 carry a copyright header: 38 say the Dart project authors (2022-2024) and 4 say The Chromium Authors — exactly lib/src/leak_tracking/primitives/_retaining_path/_connection.dart, lib/src/shared/_formatting.dart, lib/src/shared/_util.dart and test/test_infra/utils.dart, i.e. the four paths in the second stanza. The other 13 files (root and example pubspec/README/analysis_options, five lib*/DEPENDENCIES.md, lib/src/leak_tracking/primitives/README.md) carry no notice and are covered by Files: * and the root LICENSE.
• The prescan's author check found no unnamed holder; corroborated by reading the matching header line of every one of the 42 files.
• Licence keyword sweep over the whole tree found no GPL/LGPL/Apache/MPL/CC, no non-commercial or no-modification wording, no Good, not Evil, no public-domain claims: BSD-3-clause is the only licence.
• No built or binary files: no .jar/.class/.so/.js/.pdf/.dart_tool and no minified code. The orig tarball matches the tree (listed lib/, lib/src/, lib/src/leak_tracking/, test/, test/test_infra/, example/ inside dart-leak-tracker_11.0.2.orig.tar.gz), so nothing was stripped and no Files-Excluded is needed.
• The five DEPENDENCIES.md files marked Generated by https://github.com/polina-c/layerlens are markdown dependency diagrams committed upstream; their input is the source tree itself and they are documentation, not code, so this is not generated code lacking its preferred form of modification.
• Entries in debian/install (lib, pubspec.yaml -> usr/share/dart/packages/leak_tracker/) exist, as does debian/docs' README.md; no maintscripts, links, dirs or patches are needed or missing.
• Dependencies checked via apt-cache: dart-clock 1.1.3, dart-collection 1.19.1, dart-meta 1.19.0, dart-path 1.9.1, dart-sdk 3.13.4 are in the archive; dart-vm-service is built by dart-vm-service 15.4.0-1 awaiting acceptance in NEW, which satisfies (>= 11.10.0), (<< 16.0.0) and pubspec.yaml's >=11.10.0 <16.0.0.
• dh-sequence-single-binary is a virtual package provided by debhelper 14.5 on this system; the debhelper compat-upgrade checklist says the addon is implicitly active at compat 14 and should be activated explicitly via that Build-Depends, so debian/control is correct (and dh therefore emits no compat-14 single-binary warning).
• override_dh_install's touch -d "@${SOURCE_DATE_EPOCH}": dpkg-buildpackage(1) sets SOURCE_DATE_EPOCH from the latest changelog entry when it is unset, so the override cannot fail in a normal build; dh_fixmtimes normalises the mtimes again afterwards, so it is redundant but harmless.
• Autopkgtest smoke test uses only exported symbols: forceGC({int fullGcCycles}) at lib/src/leak_tracking/helpers.dart:25 (exported by lib/leak_tracker.dart), the const LeakDiagnosticConfig constructor and copyWith with the three flags at lib/src/leak_tracking/primitives/model.dart:212-244, and LeakType at lib/src/shared/shared_model.dart:16; its package_config.json is written into the same temp directory as main.dart, and HOME is made writable.
• debian/changelog: 11.0.2-1, unstable, urgency=medium, maintainer matches debian/control, date is today; version matches pubspec.yaml 11.0.2 and the .dsc. Standards-Version 4.7.4 against Policy 4.7.4.1 (first two components equal), so not an issue of any severity.
• debian/upstream/metadata and debian/gbp.conf (debian/latest, upstream/latest, pristine-tar) are consistent; debian/source/format is 3.0 (quilt) with no patches, which is fine.
• uscan found the packaged version as the newest upstream release (upstream 11.0.2, packaged 11.0.2).

• File modes are not readable with the available tools, so whether debian/tests/smoke carries the executable bit (without which autopkgtest would not run it) could not be checked.
• dart-sdk is not installed on this reviewing system, so the paths the autopkgtest assumes (/usr/share/dart/packages//pubspec.yaml, the /usr/lib/dart/bin/dart fallback) and the URI form of its generated package_config.json could not be exercised; command -v dart is tried first, so a different primary path would not break it.

None.
