OCR-confusable register match
Red tags that match no pattern and no register entry, but whose OCR-confusable skeleton (folding 0/O, 1/I/L, 2/Z, 5/S, 6/G, 8/B) lands on exactly one register tag. This is what enabling the match would reclassify as normalisable — shown here so you can verify it first.

Proposed rewrites
Nothing to rescue — no red tag's skeleton uniquely matches a register tag.
