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.
Recovers the game's event-posting API so the engine can post events and the
compare harness can see them. Until now the owner's event list was invisible to
every layer: B3's replace-mode oracle failed by exactly one item across 40,300
(an unposted EVENT_RESEARCH_OVERBUDGET) while its compare read clean, and B2's
clean compare bounds the economy fields only.
New pure module src/game/events:
* EventStorage / TurnEvents / PlayerEvent -- the list is bucketed by TURN, not
flat, which the save-editor struct notes had wrong.
* EventStorage::Post reproducing the original's rules, including the four that
change save bytes: the FLT_MAX (not infinity) default position; action 0 with
no subject and no position storing as 2; per-bucket dedup that compares
message/image/location/position/action but NOT summary; and EvNxID starting
at 0 and being promoted to 1 on the first post.
* PruneOldTurns reproduced with its off-by-one: of a leading run of buckets
older than turn-50 it erases n-1, so one stale bucket always survives. The
survivor is serialized, so correcting it would diverge.
* research_events: the five events the research path raises, their EvImg
identifiers and string-table keys, and the 0.8 completion split evaluated
against (double)0.8f rather than the decimal 0.8.
Localized text is deliberately absent: only the EVENTSUM_/EVENTMSG_ keys are
here and the text resolves through a caller-supplied lookup, as the game does.
The four event offsets the B3 hook carried as local literals now come from the
generated header; they are read off instructions rather than inferred from the
save schema.
tests/game_events: 112 checks including a replay of the event list
turn3-state.sav actually holds. ctest 31/31 -> 32/32.
docs/E-events.md carries the proposed region and Coverage wording for the next
B3 recapture.
