📝 WalkthroughWalkthroughThe change updates Qwen3.5 campaign configurations, evaluation contracts, KD dataset controls, Slurm execution, checkpoint handling, and related tests and documentation. ChangesQwen3.5 Puzzletron campaign
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The new candidate/reference evaluation flow can reuse persisted results for different checkpoints, which may produce incorrect comparison metrics and lead to the wrong candidate being selected or recovered. This should be fixed or explicitly accepted before merging; configured checkpoint paths also warrant owner awareness because they are not restricted to the campaign directory.

Replace
tensor.item()extraction with tensor comparisons. This keeps the test pattern safe if the fixture path later uses GPU tensors.As per coding guidelines, “Avoid Python scalar extraction and operators such as
tensor.item()... because they can trigger CPU-GPU syncs.”Also applies to: 134-135, 152-154

GlobalKDConfig.trust_remote_code and the fallback used by the global automodel
configuration, while preserving explicitly provided True or False values through
the existing kd_cfg/model_cfg precedence.

- Line 431: Update the checkpoint setup in the runner to read the node-level
config reference_checkpoint value, add it to the evaluation checkpoint list when
it differs from the candidate checkpoint, and exclude it from evaluator-only
settings if unsupported by that schema. Update the post-MIP runner unit test to
configure the node-level reference and assert that evaluation requests both
candidate and reference checkpoints.

Use clearer wording for the output-count caveat.
Replace “a small number of outputs” with “a few outputs” or “some outputs”. This makes the documentation more precise.

What does this PR do?
Type of change: new example
This PR adds comparable candidate selection and evaluation to the Qwen 3.5 text pruning campaign. The default path runs configured FFN candidates through the same KD and bounded evaluation contract, ranks them using LM and downstream metrics, restarts KD for the selected student from its materialized pre-KD checkpoint, and compares the resulting student with the teacher on the complete task splits.
Opt-in campaign variants enable additional Qwen architecture axes. Matching smoke and regression-plan configurations carry the same extended search grid through the orchestration path.
The supporting changes add seeded KD data ordering, stable distributed sharding, fixed validation inputs, exact configured update counts, candidate/reference/delta LM metrics, and pinned benchmark definitions for candidate screening and selected-student evaluation.
