Lane W recovered what the type is; this is what moves it. Nothing in the turn calls a
method on a child script object directly. A driver notifies the root with an integer event
id, the root fans the delivery out to every child, and each delivery is a generic handler
plus one event-specific vtable slot chosen from a 33-entry jump table at 0x007a6480. That
table is what proves the hand-written pairs lane K read in the tail are event deliveries
and not ad-hoc calls, and five of its rows are not in slot order.
Six deliveries in a turn, from five functions, with the ids they send. Three handlers
write the eight leaves that diverged: the slavers' difficulty tier (a three-record stack
table against the frame, and at frame >= 100 the scan runs off the end and stores nothing,
so the tier can never reach 2), the refugees' one-shot latch at turn begin, and the swarm
queen's hives -- registered on the systems whose EggScio equals the SWARM's scenario tag,
which the queen's constructor stores at +0x4 while its own encounter id sits at +0x8.
The hive target turn slips forward by one every turn the spawn gates fail. That single
`inc` is the whole explanation of a field that reads 31 after turn 1 and 32 after turn 2,
which no re-roll can produce on two hives at once.
Corrects combat-done-tail.md: the tail has a FOURTH script-hook site, at 0x007d9820, and
it sends event 0x1c -- the same id ProcessTurn sends, which lane K attributed to that
driver alone.
Two leaves stay blocked, and not on a workload: the refugees' design id needs handle
allocation and data-file instantiation, and the hive target turn needs one MT draw plus
two config constants behind pointers no reference initialises in a form this lane could
follow. Fitting them from a single two-hive observation would have been fitting, not
derivation, so it was not done.
An RNG claim for the next lane to falsify cheaply: lane Z's "residual outside the two turn
drivers is exactly zero" was measured on turns where the hives already existed. Hive
creation draws inside BeginProcessTurn, outside both drivers and before either.
13 addresses in ghidra/addresses.d/lane-sv.json; validated to a scratch path, merges to
1,204 with no duplicate name. A fourteenth was dropped: this lane reached 0x004271c0
independently and would have filed it as RNG_NextIntInclusive, but addresses.json already
carries it as RNG_NextInt with the same convention and four lanes depend on that name. The
merger only detects duplicate NAMES, so a second name for one address would have merged
silently and forked the vocabulary for the campaign's most-used RNG primitive.
