When does this happen?

IF Over-aggressive normalization (literal stripping) causes collision of genuinely different events.

How others solved it

THEN Use placeholder substitution ('<ts>', '<uuid>', '<n>') instead of removing volatile tokens. Preserve structural tokens to keep messages distinct.

text = _RE_ISO_TIMESTAMP.sub('<ts>', text)
text = _RE_NUMBER.sub('<n>', text)
# NOT text = _RE_NUMBER.sub('', text)
