Five hooks recaptured, build recap-7584bad-20260908T0615Z, no source change. - ProcessResearch: the over-budget event is now a compare divergence (side.events.after.v.next_id orig=4 ours=3) instead of a 609 KB save diff. 15 calls over 5 turns, 3 diverged, RNG matched 15/15. - ComputeBudget: 4284 compared, 0 diverged, guard quiet - but only 20 distinct states and 13 of 22 slots always zero. - MoveFleet: 8 of 45 calls diverge by 1 ULP of position. B4's clean verdict was a one-sample verdict. - First guarded captures for OnTechResearched (RollResearchEvent draw fired and matched), the colony turn and MoveFleet. - Guards mapped SetResearched live and found an undeclared ObservedTech append. VM140 released at the main menu, hooks=trace.

Game::TechTree::ProcessResearch — not checked by this run
- (high) posts EVENT_RESEARCH_OVERBUDGET on the owner's EventStorage in the same branch that sets node.flag = 2 — the message text is composed from the tech name, so ours cannot synthesise it; it would have to be posted through the game's own event API. This is the defect that made a clean compare false: replace mode's autosave differed from the oracle by exactly this one event [region:events (EvNxID now diverges instead of passing silently)]
- (medium) posts EVENT_TECHS_UNLOCKED for nodes that became available this turn — the trailing unlock loop makes no draw and writes no node, but it does build a names list and post an event [region:events]
- (high) TechTree::SetResearched on completion: the turn/order stamps, the child unlock cascade, the recursive research of zero-cost children, and the owner's OnTechResearched callback — its own milestone (B2); the callback writes live player state that compare mode must not touch, and it consumes one extra RNG word [guard:player, guard:tree_header]
- (medium) bumps the tree's completion-order counter (TechTree+0x20) — part of SetResearched; the per-node
orderword is compared but the counter it comes from was not a region [guard:tree_header] - (low) writes a completion line to the game log — log text is not simulation state
