TechTree::ProcessResearch's events region now compares a modelled value instead of
reporting a known defect. ours posts the pass's events into its own
sots::events::EventStorage, seeded from a scan of the owner's list taken BEFORE the
original runs, and writes only the counts into the region's scratch copy. The game's
PostEvent is never called and no live byte moves; replace mode still posts nothing,
because a bumped EvNxID with no record behind it would corrupt the oracle's save.
- game/events: PostResearchPassEvents (the decision half, pure) + KeylessEventText
- shim/hooks/event_inputs (new lib shim_events, host-tested): the live<->model adapter,
carrying game pointers as explicit uint32 so a 64-bit host build cannot alias them
- research hook: the wiring, a new observed_techs region for ServerPlayer+0x274, and
turn / events_next_id_in / events_dedup_risk in the args so the count model's own
assumption is measured rather than assumed
- EVENT_TECHS_UNLOCKED is NOT posted: its trigger is pinned but needs SetResearched's
unlock cascade, which ours does not run. The driver takes the unlock list as an input
and is handed 'no list', so a missing input cannot look like a modelled negative.
Predicted residual: next_id short by exactly 1 on a completion call.
ctest 33/33 (shim_events_unit is new), clean_room_check OK. The shim TU is
syntax-checked only: no MinGW cross toolchain on this box.
See docs/P-events-wiring.md for the exact prediction for the next VM run.
