It evaluates materialized and post-distillation checkpoints, routes VLM evaluation through a RealWorldQA profile, validates results, updates smoke tests, and documents the lifecycle. ChangesCheckpoint evaluation lifecycle
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds shared checkpoint evaluation for text and VLM workflows, but the VLM evaluation package export pattern still needs owner follow-up to ensure its public APIs are exposed consistently to downstream users. The change is otherwise mergeable with that bounded integration risk acknowledged. Sequence Diagram(s)sequenceDiagram

Expose the reusable evaluator from a non-CLI module so package imports follow the public API convention without preloading the documented module entry point. Normalize optional post-MIP mappings before profile registration. Signed-off-by: Johannes Rausch <jrausch@nvidia.com>

### What does this PR do? Type of change: documentation The Qwen 3.5 VLM pruning guide was dense and focused on implementation details, which made the checked-in smoke example harder to follow than the corresponding text example. This change rewrites it as a shorter, task-focused guide and uses symmetric “text pruning smoke” and “VLM pruning smoke” names. - Opens with a plain summary of what the one-GPU smoke test does and what its small results can prove. - Walks through environment preparation, image-text dataset setup, runner configuration, dry-run inspection, launch, and resume. - Gives one concise result checklist covering image use, physical pruning, saved-checkpoint evaluation before and after distillation, image serving, and resume. - Keeps separate checkpoint evaluation and larger-run guidance, while making clear that the setup wizard's generic pruning graph is not the maintained VLM example. The pruning, evaluation, serving, distillation, and test support are provided by [Evaluate saved pruned text and VLM checkpoints](#2280). This PR changes documentation only. ### Testing - All repository hooks applicable to the changed Markdown files pass. - Links, commands, configuration names, and documented stage names were checked against the stacked source tree. - GPU validation was not repeated for this documentation-only change. ### Before your PR is "Ready for review" - Is this change backward compatible?: yes - If you copied code from another source or added a dependency, did you follow the contributor guidance?: N/A; no copied code or new dependency - Did you write necessary tests?: N/A; documentation only - Did you update the changelog?: N/A - Did you get Claude approval on this PR?: N/A <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Updated Puzzletron guidance with links to the Qwen VLM pruning smoke workflow. * Clarified setup differences between text and VLM campaigns, recommended datasets, workflow capabilities, and campaign sizing. * Refined smoke-test documentation to cover dataset preparation, configuration, dry runs, launch/resume, acceptance checks, checkpoint evaluation, and larger-run planning. * Clarified that smoke-test budgets validate workflow correctness rather than full lifecycle correctness. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Signed-off-by: Johannes Rausch <jrausch@nvidia.com>

What does this PR do?
Saved pruned checkpoints must still work after another process reloads them. This PR adds one shared evaluation step for text and VLM and runs it after materialization and after knowledge distillation.
Type of change: new feature, tests, and documentation
AnyModelarchitecture metadata. Distillation writes another consolidated Hugging Face-format checkpoint; it does not implicitly convert the model to a nativeAutoModelarchitecture. Both use the same evaluation path.Teacher comparison is separate. Run the teacher with the same task version, data, prompt, and limits, then compare its metrics with the student results.
Usage
Use
full_smoke.yamlfor text orfull_vlm_smoke.yamlfor VLM. Each workflow runscheckpoint_evalafter materialization andpost_kd_checkpoint_evalafter distillation. Setup and artifact paths are documented inexamples/puzzletron/docs/post_mip_pipeline.mdand the modality smoke guides.Testing
The two-sample runs prove checkpoint reload and benchmark completion, not model accuracy.
