fix(docker): give the production images the Debian zimg record (issue #3242) - #3395
The production images now carry the Debian record of the libzimg they ship, so their licence notice names the package the image actually contains (issue #3242). The images copy libzimg.so* out of Debian's libzimg2 3.0.5+ds1-1+b2, but the zimg entry of production-cli-image described upstream zimg 3.0.6 and claimed no file inside the image that could answer for it.
The record.zimg of production-cli-image now reads debian_source_file: usr/share/doc/libzimg2/SOURCE and takes the package's copyright file as its licence text — field for field what the tester entry has done since fix(docker): put the staged libraries on the GPU tester images' library path #3241. The eight production records that take the component with "from" follow it (ADR-1517), so all nine published production images agree.
Six builders, as the scope note asked. Each copies the library and stages copyright + a dpkg-querySOURCE line under /dist/doc/libzimg2: Dockerfile.production:86, Dockerfile.production-gpu:130 and :182, Dockerfile.controller:98, Dockerfile.go-server:102, Dockerfile.node:184. Your note of 2026-11-10 named the go-server and node lines that the issue text had missed; a seventh copy site is the shared scripts/ci/build-oneapi-libvmaf.sh, which stages /dist/lib for the two oneAPI images and is held to the same rule.
Nine runtime stages install it at /usr/share/doc/libzimg2, including node-sycl-assembled, which inherits it from node-assembled → runtime-base rather than copying it again.
Contract.test_copied_debian_libraries_carry_their_source is extended rather than duplicated: one table over all ten stages that copy a Debian library (the tester image's four cp -a sites and the production cp -d ones), a second over the thirteen published runtime stages, resolved through each FROM chain. On origin/mastersix of ten copy sites and nine of thirteen runtime stages fail; on this branch all pass. Each entry also has to match a real copy line — Codacy's review of the first push asked for builder-oneapi2026 in that table, which copies nothing itself, so 13ef98ff0 makes an entry that matches no copy line fail instead of passing vacuously, and pins the shared script plus the two script-running stages the right way round. test_licensing_production.py pins the record itself: the production entry equals the tester entry, the eight inheriting records equal it, and macOS / the Windows zips / release-native keep their own 3.0.6 entries with no debian_source_file.
Every commit is signed off (git commit -s). See DCO sign-off.
make format && make lint is green locally — ruff (0.17.3) and black (26.10.1, the pinned versions) are clean on both touched test files; shellcheck is clean on the changed script once the work tree's CRLF is normalised (.gitattributes keeps *.sh at eol=lf, so the committed blob is LF and CI sees no SC1017).
Unit tests pass — see "What I ran" below. One environmental caveat, stated so it is not read as a pass: every test in these two files that takes tmp_path errors in this desktop sandbox (PermissionError on the directory pytest creates with mode=0o700, whose DACL then omits the sandbox SID; os.symlink is refused outright). The same 7 tests error identically on an unmodified worktree of origin/master, so it is not a regression — 56 passed / 47 errors there and 56 passed / 47 errors here, before and after the change. CI runs them in a real environment.
If I touched any SIMD/GPU code path, I ran /cross-backend-diff and the worst ULP is ≤ 2. — not applicable: no C/C++ source touched.
If I touched a feature extractor with SIMD/GPU twins, I either updated every twin or listed the gap under "Known follow-ups" below. — not applicable.
If I added a new .c / .cpp / .cu / .h / .hpp, it has the appropriate license header (see CONTRIBUTING.md). — not applicable: no new source file.
If this is a breaking change, the commit message uses ! or BREAKING CHANGE: and the migration path is documented below. — not a breaking change.
If this PR adds an ADR, the ADR row lives in docs/adr/_index_fragments/<NNNN-slug>.md … — no ADR added: the decision (read the Debian record, not upstream's archive) is already ADR-1503 rule 2's shape and the tester entry's precedent.
docs/state.md updated in this PR with a row — T-PRODUCTION-ZIMG-DEBIAN-RECORD-2026-11-10 under "Recently closed", naming the six builder lines, the shared script, the nine runtime stages and what the record now reads.
Research digest — no digest needed: the issue carries the measurement (apt-cache policy and dpkg-query on the pinned debian:13-slim base give zimg=3.0.5+ds1-1, package 3.0.5+ds1-1+b2 against the record's 3.0.6 archive commit) and names the fix shape; this PR executes it, the same relation fix(docker): put the staged libraries on the GPU tester images' library path #3241's tester change has to its issue.
Decision matrix — recorded here as the two shapes the fix could take, both already in the tree: (a) give the component a debian_source_file + an artifact text and make every copying builder stage the package's record — chosen, because it is what the tester entry and debian-libgomp1 already do (HISS-19), so one reader serves both families and the source offer names a real Debian package; (b) keep the upstream 3.0.6 provenance and change the tests to stop asking — refused, because the notice would still name a version the image does not ship, which is the bug. A third option, recording zimg as a dpkg-copied component through record-copied-debian-libs.sh, is heavier than one package needs: that script exists for the node image's closure of ldd-resolved libraries, not a single named copy.
AGENTS.md invariant note — docker/AGENTS.md gains "The Debian zimg record every copying builder stages (issue Production image licence manifest names zimg 3.0.6, the images ship Debian libzimg2 3.0.5 #3242)": the six lines, the shared script, the /dist/doc/libzimg2 → /usr/share/doc/libzimg2 rule, why omitting it fails licensing.py sources, and that macOS / Windows / release-native keep their archive entries.
Reproducer / smoke-test command — pasted below under "Reproducer".
CHANGELOG fragment — changelog.d/fixed/production-zimg-debian-record.md.
Rebase note — no rebase impact: the change touches no upstream-shared path (core/, python/, ffmpeg-patches/ untouched) and adds no ordering a rebase could silently break; the licence record and the Dockerfile lines are fork-local.

published-rc-native (licensing.json) lists release-native's components but notzimg, so if that already-published artifact were ever checked with its staged libzimg.so*, no component would claim the file. published_rc_companion.py runs notices / sources / fetch-texts only, never check, so this is unobserved rather than proven passing. Out of this issue's scope (it is about the production images) and worth its own issue.
The macOS bundle, the Windows zips and release-native keep the 3.0.6 archive entry, as the issue asks: each links zimg from upstream's source (Homebrew static libzimg.a, vcpkg static, the release container's zimg-devel), so each needs its own measurement before its entry changes.
Production container images now include Debian copyright notices and source-package/version details for the zimg library. The production CLI’s licensing information identifies the Debian-provided library and links it to the accompanying documentation. These records are included across the production, controller, Go server, and Node runtime images. Native builds continue to use the upstream zimg licensing information.
Issue VMAFx#3242: the production licence manifest named upstream zimg 3.0.6 while every production image ships Debian's libzimg2 3.0.5+ds1-1+b2, so the generated notice named a version and a source the image does not carry, and nothing in those images answered for the library the builder lines copy out of /usr/lib/*-linux-gnu*. The zimg entry of production-cli-image now reads the package exactly as the tester entry has since VMAFx#3241: a builder that copies libzimg.so* also stores /usr/share/doc/libzimg2/copyright and a dpkg-query SOURCE line under /dist/doc/libzimg2, and the runtime stage installs both at /usr/share/doc/libzimg2; the eight production records that take the component with "from" follow it (ADR-1517).
Scope is the maintainer's note of 2026-11-10, which named six builder lines rather than the four the issue text listed: Dockerfile.production, Dockerfile.node, Dockerfile.production-gpu (twice), Dockerfile.go-server and Dockerfile.controller. The go-server and node images had been missed because they inherit the component too, and a seventh copy site is the shared scripts/ci/build-oneapi-libvmaf.sh that stages /dist/lib for the two oneAPI images. test_copied_debian_libraries_carry_their_source becomes one table over every stage that copies a Debian library (the tester image's four cp -a sites and the production cp -d ones) with a second table over the thirteen published runtime stages that must install the record, resolved through each FROM chain: on origin/master six of the ten copy sites and nine of the thirteen runtime stages fail, on this branch all of them pass. The macOS bundle, the Windows zips and release-native link zimg from the 3.0.6 archive themselves and keep their entries, as the issue asks.

Production builders now stage Debian libzimg2 copyright and source metadata, and runtime images install those records. The production CLI licensing entry uses the Debian records. Tests check builder copies, runtime inheritance, licensing metadata, and native-platform entries.
Changes: Production libzimg2 licensing records
Layer / File(s)
Summary
Stage Debian package records Dockerfile.go-server, docker/Dockerfile.*, scripts/ci/build-oneapi-libvmaf.sh, tools/rc1-tester/tests/test_dockerfile_runtime_libs.py
Builder stages and the oneAPI script copy the Debian copyright file and record the source package and version under /dist/doc/libzimg2. Runtime-library tests check library-copy sites for matching source and copyright records.
Install records in runtime images Dockerfile.go-server, docker/Dockerfile.*, docker/AGENTS.md, tools/rc1-tester/tests/test_dockerfile_runtime_libs.py
Runtime stages copy the records to /usr/share/doc/libzimg2. Tests check published stages and inherited records, and the Docker guidance describes the staging and installation requirements.
Align production licensing record tools/rc1-tester/image/licensing.json, tools/rc1-tester/tests/test_licensing_production.py, changelog.d/fixed/production-zimg-debian-record.md, docs/state.md
The production CLI zimg entry references Debian’s source metadata and copyright file. Tests check the production entries and confirm native-platform records retain upstream zimg references.
VMAFx/vmafx#3241: Adds Debian copyright and source records for libzimg2 in tester images; this PR applies the corresponding licensing-record changes to production images.
Merge Risk: Low · up to 13ef9
A SYCL image can report the wrong Debian source when its builders resolve different package versions. The record checks also have limited coverage gaps; address these or accept the scoped risk.
Security architecture risk: Low · up to 13ef9
The changes mainly add package documentation without expanding runtime privileges or network access. One image can inherit a source-version record from a different builder than the library it ultimately ships, weakening provenance accuracy. An actual version mismatch has not been demonstrated.
Retained concerns
Low · architecture · inferred: The new provenance contract can associate Node SYCL's final libzimg with another builder's SOURCE record. runtime-base installs the CPU builder's record, but node-sycl-assembled subsequently overlays the oneAPI builder's library without its record. Independent package resolution or cache reuse can make those versions differ, and the new tests check record presence rather than producer identity. This affects provenance and source-package selection; an actual mismatch or runtime vulnerability is not established.
Security review details
Security Blast Radius
inferred — The identified producer-binding gap is bounded to the published Node SYCL image's libzimg provenance and associated source selection. The examined changes do not establish a new tenant-crossing path, runtime privilege gain or attacker-controlled package selector.
Trust Boundaries and Controls
inferred — The relevant trust transition is from builder-local package metadata into the published image's source declaration. Records are locally consistent with each builder, but inheritance does not preserve that association when a later stage replaces the library from another builder.
Resilience and Maintainability Implications
inferred — The shared script fails fast during sequential staging. A failed or interrupted builder RUN therefore cannot normally supply a successful downstream image stage. This contains partial-build publication, but does not resolve successful builds whose separate producers selected different package versions.

Pull Request Overview
⚠️Resolve issues before merging
One test currently fails to enumerate all production zimg copy sites, leaving a regression gap for the oneAPI builder. This should be corrected before merging so the test’s claimed exhaustive coverage is accurate.
Test suggestions
Verify each production and tester copy site records the corresponding Debian package.
Verify missing or mismatched Debian records are rejected.
Verify runtime stages install the record directly or through their FROM chain.
Verify the shared oneAPI build script records libzimg2.
Verify the production manifest matches the Debian record and inherited production components.
Verify native, macOS, and Windows components retain upstream provenance.

Good catch on the hole, but the entry itself is not the fix: builder-oneapi2026 copies nothing — it runs scripts/ci/build-oneapi-libvmaf.sh, and that script is the seventh copy site. Adding the stage to COPY_SITES would put a green assertion on an empty match.
What was actually wrong is that every entry passed on an empty match, so a stage rename, a moved copy line or a wrong copy verb would have made the contract silently vacuous. 13ef98ff0 closes that: _copied_debian_packages() reports what a stage copies, and the parametrized test now requires libzimg2 among them before it checks the record. Two tests cover this pair explicitly — the shared script is the copy site (non-empty, record present), and both builder-oneapi2026 stages are asserted to carry no copy line of their own, so moving one there gets noticed instead of quietly joining an untested site.
Verified: all ten COPY_SITES entries match a real copy line, none is vacuous, and a wrong verb reads as an empty match — the guard fires on the failure it exists for.
#3242 Production image licence manifest names zimg 3.0.6, the images ship Debian libzimg2 3.0.5 · 6 of 6 met
#
Requirement
Status
Notes
1
Have the production licence notice identify Debian's libzimg2 rather than upstream zimg 3.0.6.
✅ Met
The production-cli-image zimg component now uses the Debian package's SOURCE record and copyright file; the eight inheriting production artifacts use the same component.
2
Each builder that copies libzimg also stores the package copyright file and a dpkg-query SOURCE record.
✅ Met
The named production, controller, and GPU builder sites stage both records; the change also covers the go-server, node, and shared oneAPI copy sites.
3
The runtime stage installs both records under /usr/share/doc/libzimg2.
✅ Met
The production runtime stages install the staged directory, including stages that receive it through their FROM chain.
4
The zimg component reads the Debian SOURCE file and uses the package copyright file as an artifact text.
✅ Met
The production component points to usr/share/doc/libzimg2/SOURCE and usr/share/doc/libzimg2/copyright.
5
Extend the copied-Debian-library test to cover the production Dockerfiles.
✅ Met
The test table covers the production copy sites and checks both that each copies libzimg2 and that its record is staged.
6
Leave the macOS, Windows, and release-native zimg entries based on their own source builds unless those builds are checked.
✅ Met
Those entries remain on the upstream source record, and a test checks that they do not claim the Debian SOURCE file.

**Copied libraries escape coverage**
When a Dockerfile adds a Debian-library copy site or published runtime stage, or an existing copy site is omitted from `COPY_SITES`, `pytest` parametrizes only the hard-coded `COPY_SITES` and runtime tuples, and does not compare them with actual Dockerfile commands; `docker/Dockerfile.tester`'s `vmaf-build` copy is already omitted. `_copy_gaps` therefore never checks those sites, so CI passes while an image can ship `libzimg.so*` without its Debian record.
Discover or enumerate all actual copy sites and published runtime stages, then fail if the test coverage does not include each one.

**Runtime record checks pass without records**
When a runtime record installation is removed, its `COPY` source differs from the builder's output path, or the runtime stage merely creates the destination directory, `_inherited` includes builder commands, so the copyright source path can satisfy the assertion even when the runtime stage does not install the record. The test also checks destination-path text rather than verifying that the runtime `COPY` consumes the builder's staged `SOURCE` and copyright files; CI passes while Docker cannot find the `COPY` source or the runtime lacks the record.
Assert that the runtime stage copies the actual staged `SOURCE` and copyright files from the builder to the destination, and that the builder output path matches the runtime `COPY` source.

**Wrong source provenance passes**
When a source-built artifact has an incorrect `source` value but retains its zimg 3.0.6 text reference, `test_the_images_that_link_zimg_from_source_keep_their_own_record` accepts the stale `zimg-3.0.6-COPYING` text reference as an alternative to checking `component["source"]`. A wrong source URL therefore passes while the test claims the source-built artifacts keep their own record.
Assert the expected zimg source in `component["source"]` directly, separately from checks on the licence text.

**Scanner known-gap coverage is missing**
When a Docker copy uses syntax not matched by the scanner regex, when a Docker copy uses a form outside `_copy_gaps`’s regex, the copy-site test can pass without detecting an uncredited library. The tests cover current Dockerfiles and negative examples, but no known-gap fixture checks that limitation, leaving callers with false assurance.
Add a known-gap fixture for `_copy_gaps` and verify the documented limitation is handled or detected.
</issue_to_address>
Sourcery assessment
Needs a human reviewer. 4 findings to address first, and if the Debian package record or licensing manifest is wrong, published images may retain an incorrect source or copyright record after a revert. The impact is bounded to those image artifacts and can be corrected by rebuilding and republishing them; the added files do not change runtime behavior.

When a source-built artifact has an incorrect source value but retains its zimg 3.0.6 text reference, test_the_images_that_link_zimg_from_source_keep_their_own_record accepts the stale zimg-3.0.6-COPYING text reference as an alternative to checking component["source"]. A wrong source URL therefore passes while the test claims the source-built artifacts keep their own record.
Assert the expected zimg source in component["source"] directly, separately from checks on the licence text.

🟡 Medium · Scanner known-gap coverage is missing
When a Docker copy uses syntax not matched by the scanner regex, when a Docker copy uses a form outside _copy_gaps’s regex, the copy-site test can pass without detecting an uncredited library. The tests cover current Dockerfiles and negative examples, but no known-gap fixture checks that limitation, leaving callers with false assurance.
Add a known-gap fixture for _copy_gaps and verify the documented limitation is handled or detected.

Codacy's review asked for `("docker/Dockerfile.production-gpu", "builder-oneapi2026")`
in COPY_SITES. That stage copies nothing itself — it runs
scripts/ci/build-oneapi-libvmaf.sh, which the neighbouring test pins — so the
entry would have passed while asserting nothing. The suggestion does name a real
hole, though: every entry in the table passed on an empty match, so a stage
rename, a moved copy line or a wrong copy verb would have turned the contract
green and silent.
_copied_debian_packages() now reports what a stage copies, and the parametrized
test requires libzimg2 among them before it checks the record. Two added tests
hold the oneAPI pair down: the script is the copy site (non-empty, with the
record), and the two builder-oneapi2026 stages carry no copy line of their own,
so moving one there is noticed rather than silently uncovered.
Checked: all ten entries match a real copy line and none is vacuous, and a wrong
verb reads as an empty match — so the guard fires on the failure it exists for
rather than on a coincidence.

Keep the SYCL libzimg record aligned with its library.
If the builders resolve different libzimg source versions, this copy replaces the inherited library while retaining the CPU builder’s SOURCE and copyright. The SYCL image can then report and select the wrong Debian source. Ensure the record matches the library shipped by the SYCL image.

Check both library-copy forms in the oneAPI stages.
This assertion detects cp -d but not cp -a, which COPY_SITES also recognizes. If either oneAPI builder adds an uncredited cp -a library copy, this test still passes. Check both forms so the test detects a copy site outside COPY_SITES and the shared script. (raw.githubusercontent.com)

Summary
The production images now carry the Debian record of the libzimg they ship, so their licence notice names the package the image actually contains (issue #3242). The images copy
libzimg.so*out of Debian'slibzimg23.0.5+ds1-1+b2, but thezimgentry ofproduction-cli-imagedescribed upstream zimg 3.0.6 and claimed no file inside the image that could answer for it.zimgofproduction-cli-imagenow readsdebian_source_file: usr/share/doc/libzimg2/SOURCEand takes the package's copyright file as its licence text — field for field what the tester entry has done since fix(docker): put the staged libraries on the GPU tester images' library path #3241.

Your note of 2026-11-10 named the go-server and node lines that the issue text had missed; a seventh copy site is the sharedscripts/ci/build-oneapi-libvmaf.sh, which stages/dist/libfor the two oneAPI images and is held to the same rule./usr/share/doc/libzimg2, includingnode-sycl-assembled, which inherits it fromnode-assembled→runtime-baserather than copying it again.test_copied_debian_libraries_carry_their_sourceis extended rather than duplicated: one table over all ten stages that copy a Debian library (the tester image's fourcp -asites and the productioncp -dones), a second over the thirteen published runtime stages, resolved through eachFROMchain. Onorigin/mastersix of ten copy sites and nine of thirteen runtime stages fail; on this branch all pass. Each entry also has to match a real copy line — Codacy's review of the first push asked forbuilder-oneapi2026in that table, which copies nothing itself, so13ef98ff0makes an entry that matches no copy line fail instead of passing vacuously, and pins the shared script plus the two script-running stages the right way round.test_licensing_production.pypins the record itself: the production entry equals the tester entry, the eight inheriting records equal it, and macOS / the Windows zips /release-nativekeep their own 3.0.6 entries with nodebian_source_file.Type
