Lane P wrote the expected numbers into sots-engine docs/P-events-wiring.md §4 before this run existed. Every one held. First End Turn (ref-turn2 -> Launch -> End Turn, shim.cfg.recapb3 unchanged, build eventlive-dd38117-20260908T0916Z, main dd38117 with no source change): 3 calls, 3 compared, 0 divergent, tracecmp exit 0 — where lane R's run exited 1 on side.events.after.v.next_id orig=4 ours=3. Call 0 read turn=3, events_turn_bucket_exists=true, events_next_id_in=3, events_in_turn_bucket=1, events_dedup_risk=0, no events_scan_truncated, next_id 3->4 on both sides, turns/turns_bytes 2/48 unchanged, node[144].progress 2879->5768, flag 1->2, rng identical — the whole predicted list. Five End Turns: exit 1 with 2 divergent calls instead of 3, each short by exactly 1 (next_id orig 7 ours 6, orig 12 ours 11) = the deliberately unmodelled EVENT_TECHS_UNLOCKED. A 0-divergence result there would have been suspicious. sizeof(Game::ObservedTech) = 44 measured live: observed_techs.bytes grew by exactly 44 on both completion calls (440->484, 484->528), confirming lane X's static pin behaviourally. Non-researching players measured 880 = 20 x 44 and never moved. One deviation from lane R, and it is a workload effect, not a defect: rng diverged on call 9 because the completed tech had research_roll_pending set and the OnTechResearched callback drew one word ours does not (left 374 vs 375). Lane R's "RNG matched 15 of 15" was workload luck; the honest statement is that the rng region matches on every call that does not complete a roll-triggering tech. Zuul double roll CLOSED. No species-5 save existed, so this lane made one: a custom game with only Zuul in the Available Species pool, 4 End Turns under the same compare config. 8 calls, 8 compared, 0 divergent, exit 0; all four researching calls have species=5 and advance the generator by two, not one (left 540->538, 522->520, 504->502, 485->483), and ours reproduced every post-state bit-for-bit. Save added as verify/results/saves/zuul-turn5-species5.sav. End-Turn oracle byte-identical to lane R's on the first turn, so none of this perturbs the game. clean_room_check OK and host ctest 33/33, run as separate commands. VM140 restored to the recap build at the main menu and released.

Game::TechTree::ProcessResearch — not checked by this run
- (medium) posts EVENT_RESEARCH_OVERBUDGET on the owner's EventStorage: ours reproduces the decision and the id sequence, so region:events compares next_id, but the composed EvDsc/EvMsg text is not reproduced and no region can see it — text comes from the game's string table, which the engine must not carry; ours posts into its own EventStorage and writes only the counts into the scratch copy, so no live byte moves and replace mode posts nothing at all [region:events]
- (medium) posts EVENT_TECHS_UNLOCKED once after the per-node loop, for the nodes SetResearched made available this turn — the set comes from the child-unlock cascade, which ours does not run; the pass driver takes the unlock list as an input and is given
no listrather than an empty one, so a missing input cannot look like a modelled negative. Expect region:events to under-count next_id by exactly 1 on every call that completes a tech [region:events] - (high) appends to the owner's vector (ServerPlayer+0x274) on every tech completion — serialized ServerPlayer state that no coverage note in B2 or B3 mentioned until lane R's guard caught it. The element is now fully pinned (sizeof 44, {u16 turn_first, u16 turn_last, bool detected, string tech_name, int with}) and the append de-duplicates by tech name, but ours still does not append; the region reports the byte span, which must grow by exactly 44 per completion [region:observed_techs]
- (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
