In `@docker/customizer/removals/files/nmp-automodel-training.txt`:
- Around line 6-14: Validate the DALI bundled-library removals with a minimal
end-to-end decoder fixture rather than package importability alone. Apply
equivalent decoder validation to
docker/customizer/removals/files/nmp-automodel-training.txt lines 6-14 and
docker/customizer/removals/files/nmp-unsloth-training.txt lines 6-14, or narrow
both manifests to libraries proven unused; preserve decoder functionality in
each cleanup.
Apply the same fix in `@plans/2026-08-19-image-package-file-cleanup-plan.md`
around lines 693 - 703: The plan currently specifies import-only validation, so
it must reflect the native decoder coverage or the narrowed manifest scope.
In `@plans/2026-08-19-image-package-file-cleanup-plan.md`:
- Line 18: Update the plan’s image-specific removal-list commands to use a
defined CVE_TRACKER_ROOT variable instead of the hardcoded
/Users/rsadler/src/cve-tracker path, and run the commands from that directory so
contributors can execute them without editing the plan.
- Line 6: Remove the “REQUIRED SUB-SKILL” plugin invocation from the plan’s
agentic worker instructions, and replace it with repository-local workflow
guidance that does not reference plugin-based skills or slash commands. Keep the
existing task-by-task and checkbox tracking guidance.
- Around line 755-761: Update Step 6 to run the complete validation suite:
retain the targeted Ruff check, add uv run pre-commit run -a, and add a ty
type-check command covering the new Python helper and smoke tests.
- Around line 599-601: Correct the single-quoted ripgrep patterns in the cleanup
validation checks, including the occurrences around the Dockerfile references
and the additional repeated locations, by using one backslash before literal
dots such as .txt and .3. Preserve the existing search targets and validation
behavior.
In `@tests/smoke_gpu/test_rl_training.py`:
- Around line 237-239: Mark test_soundfile_libsndfile_removed in
tests/smoke_gpu/test_rl_training.py with smoke_nmp_rl_training, and mark the
corresponding cleanup test in tests/smoke_gpu/test_customizer_automodel.py with
smoke_nmp_automodel_training, unless that target is verified to invoke it
without marker filtering.

Summary
Generalizes the ad hoc codec-file cleanup used in the automodel and RL training images into a shared, per-image removal-list convention, and adds a matching apt-package removal step so unused codec libraries are purged both from apt's dpkg database and from the filesystem.
Changes
docker/scripts/remove-listed-apt-packages.sh, which purges any installed packages named in a list file (skipping ones not installed), mirroring the existingremove-listed-files.shpattern.docker/customizer/removals/:apt/nmp-automodel-base.txt,apt/nmp-unsloth-training.txt,apt/nmp-rl-base.txt(apt packages to purge, e.g.libsndfile1,libmp3lame0,sox).files/nmp-automodel-training.txt,files/nmp-unsloth-training.txt,files/nmp-rl-training.txt(bundled/non-package-managed files, replacing the old per-imagecodec-file-removals.txt).Dockerfile.nmp-automodel-base,Dockerfile.nmp-unsloth-training, andDockerfile.nmp-rl-base, running it alongside the existingapt-get update/openssl upgrade step and folding inapt-get clean.Dockerfile.nmp-unsloth-training's lateapt-get install --only-upgrade opensslblock earlier so it runs together with the new package removal, rather than as a separate late-stageRUN.Dockerfile.nmp-automodel-trainingandDockerfile.nmp-rl-trainingat their newfiles/removal lists instead of the oldcodec-file-removals.txt; update the correspondingplatform-workspaceDockerfiles'COPYpaths to match.Dockerfile.unsloth/Dockerfile.platform-workspacenow copies in the removal list and script, andDockerfile.nmp-unsloth-trainingrunsremove-listed-files.shin its late build stage.apt-get autoremovefromDockerfile.nmp-rl-base's late cleanup stage, since removed dev tooling no longer leaves orphaned dependencies to sweep.tests/smoke_gpu/python_package_versions.pywith a sharedassert_python_package_min_versionshelper, and add minimum-version smoke tests fornmp-automodel-training,nmp-customizer-tasks, andnmp-rl-trainingto catch accidental package downgrades from the new removal steps; add a DALI-still-importable smoke test to guard against over-aggressive file cleanup breaking codec-adjacent GPU libraries.Why
The codec cleanup for release image scans was previously a single hardcoded file list per image (
codec-file-removals.txt) with no way to also remove the apt packages that own those files, so the underlying packages stayed installed and could reappear in CVE scans. This consolidates cleanup into a consistent, per-image, two-pronged (apt + file) removal mechanism that's easy to extend to additional images (unsloth now included) and image-specific packages.Summary by CodeRabbit
