Legacy reports list the same `(race, className)` pair across several roster rows; the engine likewise creates one ShipGroup per arrival. Both the legacy parser and `TransformBattle` were keyed on shipClass without summing — only the last row / group's counts survived, so a protocol's destroy count appeared to exceed the recorded initial roster. The UI worked around this with phantom-frame logic. Both parser and engine now SUM `Number`/`NumberLeft` across rows / groups sharing the same class; the phantom-frame workaround is gone. KNNTS041 turn 41 planet #7 reconciles: `Nails:pup` 1168 initial − 86 survivors = 1082 destroys. The engine's previously latent nil-map write on `bg.Tech` (would have paniced on any group with non-empty Tech) is fixed in the same patch — it blocked the aggregation regression test.
