## Summary Consolidates the complete reviewed fix stack for #2375 into one DCO-safe commit: - harden package exports, measurement semantics, wrapper handling, and actionable calibration errors - validate exact installed GDN identities plus ModelOpt dynamic subclasses; reject lookalikes, ordinary subclasses, incomplete layers, and partial layer sets - make stale checkpoints saveable and restorable while keeping deployment export strict - make DASC recalibration replace and deduplicate existing mode state without stale-metadata refresh - record the declared decay-parameter checkpoint storage dtype and use derived FP16/BF16/FP32 rounding bounds - preserve BF16/FP16 storage and wider/cross-dtype reload compatibility without globally widening FP32 tolerance - add installed Transformers path coverage, optional Megatron gating, lifecycle, tamper, lossy-cast, and mixed-layer regressions - document the explicit storage-dtype contract This consolidated PR supersedes the mechanically stacked review-fix PRs #2377, #2378, #2379, #2380, #2382, #2383, #2384, and #2385. Its tree is byte-identical to the independently reviewed leaf commit from #2386. ## Validation - focused DASC suite: 23 passed, 1 absent optional Megatron skip - DASC plus weight sparsity plus attention sparsity compatibility suite: 134 passed, 1 optional skip - DASC package coverage: 408/408 statements, 100% - full pre-commit on all touched files: passed - real Transformers Qwen3NextGatedDeltaNet BF16 storage to FP32 reload smoke: passed - commit author and Signed-off-by identity both use kaix-nv <kaix@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added support for configuring decay-parameter storage precision with FP16, BF16, or FP32. * Added safer recalibration that replaces existing DASC state. * Expanded compatibility with supported GDN adapter classes and model wrappers. * Added improved validation for sparsity policies, measurements, model structure, and decay parameters. * Added support for perplexity-retention values above 1. * **Documentation** * Clarified evaluation responsibilities, recalibration behavior, stale-policy handling, supported adapters, and dtype requirements. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: kaix-nv <kaix@nvidia.com>

Follow-up to #2377 for its CodeRabbit consistency finding.
The DASC perplexity ratio allows values above 1.0, so the configurable minimum gate now accepts any finite positive value as well. The test exercises a 1.0002 minimum against a 1.0004 measurement through full calibration and policy export.
