Add Qwen 3.5 multi-axis VLM pruning campaign - #2348
Conversation
📝 WalkthroughWalkthroughThe PR replaces Qwen 3.5 0.8B campaign examples with VLM dataset preparation, multi-axis pruning, candidate evaluation, distillation, serving, and resume support. It also adds CPU resource routing, setup validation, atomic bundle publication, and focused tests. ChangesQwen 3.5 VLM campaign
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The updated orchestration validation test checks the wrong error message for its invalid embedding-pruning configuration, leaving the intended failure path incorrectly covered. This is a bounded test-only issue that should be corrected before relying on the test. Suggested reviewers: Caution Pre-merge checks failedPlease resolve all errors before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the error emitted by the configured validation branch.
The fixture enables embedding_pruning with an empty widths list. The production validation raises embedding_pruning.enabled requires at least one width, but Line 339 checks for embedding replacement scoring requires at least one width. Update the assertion to match the configured validation branch.
Proposed fix
- assert "embedding replacement scoring requires at least one width" in result.stderr
+ assert "embedding_pruning.enabled requires at least one width" in result.stderr📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

What does this PR do?
The Qwen 3.5 0.8B example had grown to 13 overlapping run recipes, including separate extended, quality-comparison, and lifecycle variants. Their responsibilities and configuration were duplicated, so it was unclear which recipe to use for a quick integration check or a complete campaign.
This PR reduces that surface to three entry points: one complete lifecycle smoke per modality and one illustrative VLM campaign. The shared bounded-search settings remain reusable implementation details rather than separate MIP-only recipes.
Recipe consolidation
Multi-axis campaign
Evidence boundary
Every remaining recipe is compiled in unit tests to catch configuration, stage, and resource drift. The current campaign has not been run end to end. Retained historical measurements used earlier recipes, so they do not establish the performance of this campaign. The KD budget and selection rule are example settings, not recommended defaults.
Testing
Focused and broader Puzzletron unit tests and repository checks passed. One host-specific atomic-directory-exchange test was skipped because that capability is unavailable. No GPU campaign was run for this change.
