Change

• Consolidate fix: adapt vLLM 0.31 collector runtime contracts #588, fix: preserve native MoE activation and routing contracts #589, fix: release completed KDA prefill buffers #595, fix: align Kimi verify collector with native state layout #597, and fix: release native MoE layer cycles after collection callbacks #598, including the duplicate MoE cleanup in fix: compose MoE cleanup with live collection failures #603, for Tianhao's collector review.
• Adapt vLLM 0.31 compute-scale, GDN, KDA, MiniMax MSA, and MoE to the audited native APIs. Preserve KDA cache/layout contracts, MoE activation and precision checks, input-weighting failure guards, and callback buffer cleanup outside timing.
• Include the narrow compute-scale companion finalization fix from fix: qualify TRT-LLM rc29 collectors for Dynamo 1.6 #568: its static and dynamic-derived outputs must finalize together. The rest of fix: qualify TRT-LLM rc29 collectors for Dynamo 1.6 #568 is unrelated TRT-LLM work and remains separate.
• Preserve runtime helper dependencies from fix: vLLM 0.31 attention compatibility #604. Campaign filtering, general recovery fixes, live failure reporting, and data publication remain outside this review.

Review order

• Stacked on fix: vLLM 0.31 attention compatibility #604 (attention); this diff contains only recurrent/MoE additions. Retarget to main after fix: vLLM 0.31 attention compatibility #604 lands.
• Communication qualification remains fix: retain communication dispatch and failure evidence #591. Tianhao's data: 2026-10 campaign — vLLM 0.30.0 / TRT-LLM 1.3.0rc29 / SGLang 0.5.21 perf tables for 8 systems #517 is the data update path; its current vLLM 0.30 measurements do not themselves qualify vLLM 0.31 timing reuse.
• Preserve original branches, commit identities, and measurement evidence. No merge, default promotion, or collection restart is part of this consolidation.

Validation

• 522 focused CPU tests pass, including compute-scale finalization/recovery, registry contracts, GDN, KDA, MSA, MoE precision/activation, callback lifetime, and import surface.
• Ruff, formatting, and diff checks pass. Consolidation required one import-order adjustment; KDA matches fix: align Kimi verify collector with native state layout #597 and the composed MoE implementation matches fix: compose MoE cleanup with live collection failures #603.
• Both consolidated commits are GPG signed and DCO signed. Full CI will be requested for the exact head; no new GPU qualification is claimed.
