Read out of dumps/sots.exe: .rdata bytes at 0x00a2c788 are 00 00 00 3f (float 0.5); the following word 0x00a2c78c is float 100.0, so this is a float32, NOT the double an 8-byte read would suggest (that reads as 5.28e13). CONSEQUENCE, measured on the live game: ResErrRoll survives into ProcessResearch only while progress/cost <= 0.5 at the START of the turn, so the OnTechResearched draw (0x0088df20) can fire only when a single turn supplies more than half the target tech's remaining cost. See the board's `research_roll_pending save` row",
