2026-08-27 clinical ve2e model forward path audit
Audited active model input, output, aggregation, ISUP, device, and precision contracts.
Work Done
- Inspected all architectures selected by the ve2e Lightning model factory.
- Traced volume, slice, quadrant, segmentation, main-weight, and EMA forward paths.
- Proposed one generic invocation adapter with separate task aggregation.
- Identified the unsupported MRIPTPCA branch and nested-logits defect in
nnUNetClassBase.
- Made no changes to the ve2e repository.
Lessons Learned: Pitfalls
- The knowledge base has no
clinical workstream index or SOP despite clinical work being an allowed category.
- The nominal common output contract is violated by
nnUNetClassBase; factory membership does not prove runtime conformity.
Lessons Learned: Improvements
- Document the shared ve2e batch and output schema, including
use_amask, slice and quadrant axes, deep supervision, and logits normalization.
- Add a clinical workstream index and SOP entry for code-only clinical model audits.
