Rescan both targets against all 5 MOADs (2026-04-03).
New defect:
- transformers-0004: wav2vec2, wav2vec2_phoneme, esm tokenizers call
self.all_special_ids/@property inside per-token decode loops, rebuilding
list every iteration. O(T) -> O(1) fix: cache set before loop.
wav2vec2_phoneme also has type mismatch (str vs list[int]), making
the check always False, leaking special tokens.
9/9 unit tests PASS.
Existing defects confirmed still present (not re-filed):
- transformers-0001/0002/0003: unchanged from 2026-03-31 scan.
- vllm-0001/0002: unchanged from 2026-03-31 scan.
MOAD-0002/0003/0004/0005: CLEAN on both targets (see SCAN-2026-04-03.md).
SCAN-TODO.md: marked transformers and vllm as complete with full summary.
Also includes UNDF stamps on jicofo-0001, jicofo-0002, langchain-0002 patches
from prior generate_undf.py run.
