Produces the game states several board rows were blocked on, and reads each
one back out of the save before claiming it.
- CD/TurnCommands_v5 decoded: three saves with issued orders (research target,
research boost, build orders, system rates, colonize, fleet move). Layout in
SAVE_FORMAT.md section 11; ids cross-checked against the same file's Sys/Flt.
- Waypoint type 3 (NodeRoute) now has 16 instances in one save and the player's
own fleet is a mover in two. Type 2 is shown NOT to be produced by a Move
order for either node-drive race (Zuul and Human both emit type 3).
- research_roll_pending true at load in two saves; the ProcessTurn gate constant
at 0x00a2c788 is a float 0.5, so the flag survives into ProcessResearch only
while progress/cost <= 0.5 at the start of the turn.
- Budget tail: construction and a large maintenance are live; Nexp is empty in
all 11 saves and the 1.8 UI has no expense slider, so slot 12 looks dead.
VM140 restored to the original 8-file SavedGames set (autosaves byte-identical)
and left at the main menu; VM140 row set FREE.
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.
