Not invulnerability: two-player-alternating variation selected by the TAS

Edge-triggered [98W] log at the mem_write8 capture site (value-changing writes, frame floor 400 — the RESET-held boot window re-inits $98 every frame via the $FC86/$FBFE toggle and exhausted the first cap by f=41). (d) The [PAC] lvl=8 anomaly resolves: $99 is the GAME VARIATION register, not level — the TAS's 30-frame SELECT hold (f=280-310) advanced it to variation 8, a two-player alternating variation per the Atari game-variation table.
