Closes B3's oracle gap and B2's known gap. Both milestones write into the
owner's event list; nothing modelled it, so their clean compares bounded the
economy fields only.
Container: EventStorage embedded at ServerPlayer+0x29c (0x1c bytes), verified by
ServerPlayer::GetEventStorage 0x0080db00 whose whole body is 'lea eax,[ecx+0x29c];
ret'. EvNxID at +0x14 == player+0x2b0, exactly the byte run the harness guard
reports. The list is a vector<TurnEvents{int EvTurn; vector<PlayerEvent>}> --
bucketed by turn, not flat, which the save-editor struct note had wrong.
Entry point: int __thiscall EventStorage::PostEvent(this, std::string BY VALUE,
std::string BY VALUE, void* obj, Vector3* pos, int turn, const char* img,
int act), 0x008862b0, RET 0x4c. 161 call sites in 110 functions: this is the
whole simulation's event API, not a research helper. Dedup is per turn bucket on
message/image/location/position/action but NOT summary; act 0 with no subject and
no position is stored as 2; EvNxID starts at 0 and is promoted to 1 on first post;
PruneOldTurns drops buckets older than turn-50 with an off-by-one that always
leaves one stale bucket behind.
Record: 0x74 bytes, EvEID(+4) EvDsc(+8) EvMsg(+0x24) EvLoc(+0x40) EvPos(+0x44)
EvImg(+0x50) EvAct(+0x6c) EvCID(+0x70) -- confirmed field by field against
turn3-state.sav, which contains the EVENT_RESEARCH_OVERBUDGET record itself.
B3's defect is fully explained: 0x00587b97, reached only from the
completion-roll-FAILED branch, under !wasDone && nowDone && owner.
Three note corrections: EvPos defaults to FLT_MAX, not infinity (writing +inf
changes the save bytes); the save array is turn-bucketed, not flat;
EVENT_TECHS_UNLOCKED has no 'parent researched' clause.
56 entries added to ghidra/addresses.json (header regenerated); 11 prototypes,
13 labels, 12 comments and 2 structs written back to the Ghidra project.
