rec+4 = 0 (the early-exit path built-in 69 actually tests) sticks for 60s with
all three squadrons poked, and neither the phase nor +16 changes. +16 stayed 2
while the handle it derives from read zero.
Leading explanation: the phase-1 condition coroutine is not polling. Both pokes
persist untouched and nothing recomputes anything, which fits the polls at
0xF524 living in a coroutine that only runs when a trigger starts it
(built-in 1, fed from [phase+272]).
But the honest problem is bigger: two pokes have now produced no observable
effect and I cannot tell 'the game ignored the write' from 'the write never
reached the game'. The stick test only proves the value persisted in the
shared-memory FILE, not that Canary's guest sees it. That control should have
come first, so both null results are downgraded to INCONCLUSIVE rather than
evidence about the condition.
Next: poke something with a visible effect (player hull, a HUD counter) and
confirm it on screen before trusting any further null result. What still stands
from these runs is only what was observed rather than poked -- the arrivals,
ADN111's destruction, and the mission-over branch.
