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.
Reads: TechTree::PrereqsMet 0x0057d8e0 (AND of ORs; zero groups TRUE, an empty
group FALSE), the prerequisite layout at TechDef+0x88/+0x98, the tail collector
0x00587cc3, and the head of OnTechResearched (RecordObservedTech unconditional;
the research-event roll gated on ResT == def && ResearchRollPending).
Live: 35 compared calls over three workloads, 0 divergences, tracecmp exit 0,
End-Turn oracle hashes unchanged. The EVENT_TECHS_UNLOCKED residual lane P
predicted and lane V measured is closed by running the cascade, not by posting
on completion.
12 new addresses in ghidra/addresses.d/lane-u.json (header 615 -> 627).
objects/layouts.json is a memory-layout projection: build() sorts fields by
off_abs (89 of 386 classes have offset order != write order) and merges
duplicate offsets into alt_tags, which is exactly the JewelsOfTheCrown
double-tag trap. Both losses are the substance of the on-disk format.
tools/streams.py is a second projection of the same recovery that keeps the
program order Lab.layout() already computes and the repeated tags, and drops
every memory fact — no off, size, sizeof, gaps or strides. The engine must read
and write the format, not inherit the original's ABI.
tools/gen_stream_schema.py emits sots-engine's include/generated/sots_stream_schema.h
under the same discipline as gen_addresses.py: generated, provenance header,
never hand-edited.
386 classes, 2042 wire items.
