The queue stamped each entry's deadline when the press was made. That reads
right and has a hole in it: a cast pushed back twice (`SMSG_SPELL_DELAYED`)
ends after the window a press made at its start was given, so the entry
times out while the thing it is waiting for is still running — and the press
vanishes with no packet, no error line and no cast. That is the one failure
mode a player cannot describe, and it is exactly the class of bug the press
queue was supposed to remove rather than introduce.
The same hole swallows a press held through a cast whose global cooldown
then outlasts the window, which is the ordinary case rather than an edge
one: a 500 ms window, a cast that ends, and 1.5 s of global cooldown behind
it.
So a slot now keeps the window and the base it is measured from, and the
drain ratchets that base forward — only ever forward — past every live
guard: the cast's reopening, the channel's trimmed end, and the global
cooldown's. An entry gives up when nothing is holding it back any more and
the window has run out since, which is what "how long past the guard's end"
meant all along.
Scripts keep a fixed deadline. Their contract is "after queued spells", and
a script whose spells never fired has nothing left to run after.
