tools/standalone_report.py drives sots-engine's sots_turn over each
consecutive-turn save pair and diffs the result against the game's own
post-turn save with state_checksum.py, which localises to named leaves and
proves its own coverage by re-serialisation.
turn1-state -> turn2-state baseline 209 diverging, after 204, closed 5
turn2-state -> turn3-state baseline 108 diverging, after 103, closed 5
regressed 0 on both
`regressed` is reported next to `closed` and never netted off. It earned its
place immediately: committing the phase-31 player-status restore turned two
agreeing leaves into disagreeing ones, because the phase writes 1 and the file
carries 4.
The stable-system stand-in feeding the colony pass is a labelled hypothesis and
it survived a changed workload -- the same 3 ntdev leaves closed on both pairs,
six agreements, zero disagreements.
Two things deliberately NOT implemented: the TShn/ltis counters (18 leaves, a
`+1` would close them, but "+1 across one observed turn" is a hypothesis, not a
reading), and the RNG state write-back (an advanced-but-incomplete generator is
wrong in a different way from an untouched one).
dashboard.py gains section 6, reading verify/results/standalone/status.json:
phases modelled/committed per driver, baseline vs after, closed vs regressed,
the subsystem breakdown of what still differs, and the RNG gap. Sections 6-8
renumbered to 7-9; the delta footer tracks the two new counts.
DASHBOARD_README.md documents every number.
findings/control-flow/standalone-scaffold.md has the ranked blocker list.
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).
