Measured over all eleven saves with state_checksum, not derived:
* the reference pair posts TWO events (turn1->turn2) and THREE (turn2->turn3),
and only two players in the whole corpus ever hold an event -- the human and
the one AI empire that owns colonies. The dormant shadow empires pick research
targets every turn and still post nothing.
* order within a player is readable off the ids: the build pass posts before the
research pass. Ids are per player, so no cross-player order is observable.
* the event type is the EvImg string and it is composed at run time --
EVENT_ENEMY_INCOMING_Human carries a species suffix, so the type space is not
an enumeration.
Two corrections in place (rule 11):
* the turn PostEvent is handed is the FRAME, not ModCount. turn2-state.sav has
Frame 2 and ModCount 12, and every event it carries is in bucket EvTurn=2. It
is the post-increment turn: a turn run from a save at turn N posts into N+1.
* the EVENT_NO_RESEARCH gate: 0x00584e50 is TechTree::CollectResearchedTechs,
not a ListAvailableTechs, and the middle test is "nothing was researched on
this turn or later" -- not "no affordable tech". zuul-turn23 exercises it: the
human posts RESEARCH_COMPLETE on turn 22 with no no-research event that turn,
then NO_RESEARCH again on turn 23.
ghidra/addresses.d/lane-ev.json records the gate at 0x0089162a with the argument
order re-read from the instruction stream. Validated with tools/gen_addresses.py to
a scratch path (1121 entries, no duplicate); the shared header is NOT regenerated.
tools/standalone_report.py gains --engine-arg (repeatable), so a lane can feed the
standalone the operator inputs a save does not carry -- the data root, the AI
roster, which blocked phases may commit -- instead of hard-coding them. Every run
records what it was given, in the report header and in status.json.
Closes five of lane AI2's open items and corrects two published claims.
The stepping order: StrategyServer::ResumePlaying 0x007ddc90 walks the player
array in INDEX ORDER and raises SEResumePlaying at each live player; the app
callback StrategyApp::OnClientEvent 0x00838e10 delivers it inline for humans
and appends it, deduplicated, to the pending queue for AI players. So the AI
players are stepped in save player order, each at most once -- computable from
a save with no live measurement. AI2's search missed it because 0x00b29f98 is
not a pointer to the StrategyApp, it IS the StrategyApp: the enqueue writes the
absolute member address 0x00b29fb4 and never materialises the object base. The
enqueue also has zero direct callers and no vtable slot -- its address is stored
into StrategyServer+0x170 by CreateGame. Lane B6's third blind spot, twice over.
The two passes: `pass` is a tier index, not a plan/act switch. 0x006abb2a picks
between two per-candidate quota fields -- tier 0 takes +0x10, tier 1 takes +0x14
-- and the hub loops `for (i = 0; i <= pass; ++i)`. Every order-emitting exit is
gated pass == 1 (0x006bbd50, 0x006c16c0, 0x006cea50), so pass 0 claims each
task's minimum force in priority order and WRITES NOTHING. That halves the
ModCount arithmetic.
Corrections:
- AI2 §4.2: the nine "no order method" tasks are not planners. All nine emit
orders at depth 4-9; the depth-4 cut hid it. AITColonize reaches list 7 and
AITBuildPoliceShips reaches list 3, which is what their names promise.
- AI2 §3: the two priority overrides' flag polarity is inverted. The tunable
applies when bit 0 of +0x4 is SET, and "committed" is not a supported name.
- AI2 §10.6: the .data invade tunables have no loader. 650 and 750, image
constants, exactly one reader each and no writer anywhere.
Also: slot 12 named (a preemption permission, 0x006a8d20), slot 13's consumer
found (0x00696620, a range budget -- and the Zuul are exempt, a FOURTH
independent cross-check on AI2's species reading), slot 11's dispatch located.
ServerPlayer+0xf9/+0xfa -- the two bytes that decide whether a player is
AI-controlled -- sit in a hole in the serialised layout and are NOT in the save;
their writer is unfound and is the biggest remaining hole.
Static only; nothing here has run under an instrument. 160 indirect call sites
inside the AI closure are unresolved, so reachability is still a lower bound.
Four predictions with falsifiers in §7.
ghidra/addresses.d/lane-ai3.json: 15 entries, 1,105 -> 1,120, no duplicates,
validated to a scratch path.
TShn: the brief's address was wrong -- player+0x274 is observed_techs; the TShn map is
ServerSystem+0x274. The real obstacle is that a std::map's nodes are heap-allocated, so there is
no fixed leaf to arm; arm the map header to trap the insertion instead.
rcex: closed from the corpus, no VM time needed (see rcex-explained.md).
Trade/spy workload: not attempted, and lane H's reasons still hold. What is new is that the
watchpoint module is the instrument for confirming the workload BEFORE spending a turn on it --
both containers are one add from the arming point, and for the spy vector the trapped return
addresses would name the UI nobody has found.
Multiplayer: two clients on one guest, joined by typed IP and by LAN browse, launched a
2-player game and played two turns in lockstep. 44,319 packets captured outside the guest,
ZERO to any GameSpy port. Availability check fails open exactly as lane G2 read it; Join
Manually is enabled with every gamespy.com name dead, falsifying G2's own caveat (a). The
shipped MOTD is fetched live from kerberos-productions.com and tells players to host in LAN
mode -- the developer's own statement of the same finding.
Watchpoints: a new shim module arms DR0-DR3 from StrategyServer::ApplyAllTurnCommands.
ModCount takes exactly 12 writes per End Turn (lane A2's prediction, confirmed twice, both
predicted addresses exact); Frame takes exactly one, from BeginProcessTurn+0x2a, settling the
ModCount-vs-Frame naming in A2's favour. The Player.Status writer between tail phase 31 and
the autosave EXISTS and is StrategyNetworkClient::OnMessage+0xa15 -- correcting lane T2.
Rule 19 control: the armed run reproduced the determinism oracle byte for byte.
rcex: closed from the corpus alone. It is sixteen 4-bit per-player counters; nibble p is set
to 1 on the turn the system enters player p's AFlags and ticked to 0 the next turn. 7/7
across two different games.
BuildQueue::ProcessTurn 0x00890d50 disassembled to the next function start (Ghidra says 1230
bytes; the body is 1264 and its end lands inside the epilogue -- rule 17 again). Corrects the
recorded prototype: the first stack argument is the StrategyServer S frame, not the system, so
the build-completed event goes on the sim and the hull's turn stamp is Frame.
THE HEADLINE IS A CORRECTION. Lane E2's open census leaf (shpt[0], one destroyer short on both
reference pairs) cannot be closed by S11's build-queue sub-pass: measured over the corpus, both
reference saves carry three empty BQ frames, every hbq false, and the one TurnCommands_v5 block
empty. The order is created inside the turn by the AI -- PvSav shows 11,900 leaving the treasury
before spine phase 0. The blocker moves to game/ai.
Also: the per-class built counter has EXACTLY ONE writer in the image (image-wide byte scan);
ShipRecords sized by enumeration; the ship/fleet birth chain end to end, correcting lane B5 --
FtFlg 0x400 is set by EVERY fleet born through the create path, not by retreat; one home fleet
per system cached at ServerSystem+0x238; and a third indirection class vtable_map.py cannot see
(the ship-borne wrapper is dispatched from a stack-built pointer table).
21 addresses in ghidra/addresses.d/lane-b6.json, validated to a scratch path against the merged
set (1,077 entries, no duplicate names); two entries dropped as duplicates of lane B5's and
recorded as agreements instead.
findings/subsystems/treaty-turn-stamp.md. Briefed on the post-combat tail, ranked its
phases by leaves-closed-per-effort against the standalone's 158-leaf residual, and found
that every tail phase which moves a leaf in this corpus is blocked on another lane
(ship construction, the budget) or on the tail's vtable blind spot. Section 5 lists that
ranking with the numbers. The two items below are what a lane holding no VM could close.
1. StrategyServer_StampTreatyTurns 0x007898c0, read as instructions. The diplomacy
ledger's per-turn stamp over every ordered pair of players holding a treaty, creating
the entry on demand. Sole caller is ApplyTurnCommands, so it is a HOST step and not a
tail phase. Three corrections to strategic-turn-internals.md 5.2, which is flagged in
place: the relation codes are 3=ally / 2=NAP / 1=cease-fire and not the reverse (which
combat-done-tail.md 2A already implied independently); the stamped value is Frame, not
ModCount; and the bit is the PlyrIdx field, not the player's vector position -- the
opposite convention from the shared-vision mask.
Modelled in sots-engine as host phase H02. Predicted 26 leaves on the reference pair
and 14 on pair 2 before building; measured exactly 26 and 14, 0 regressed, and +12 on
each of three further pairs from a different game at turns 2, 15 and 16 that the model
was never fitted to. 76 closed / 0 regressed over five pairs, 0 RNG words. The rule
also reproduces the ledger of ten of the eleven corpus saves entry for entry.
2. Player.Status. backlog.md item 6 has it blocked on "the writer between tail 31 and the
autosave -- watchpoint". There is no such writer. A whole-image scan for immediate
stores to ServerPlayer+0x164 finds exactly three: ProcessTurn's encounter loop writes
1, ResumePlaying writes 0 on load (the 4 -> 0 the determinism note recorded), and
StrategyServer_MarkPlayerTurnEnded 0x00821a40 writes 4 from the three End Turn
SUBMISSION paths, which run before the turn is processed. Item 6 needs one predicate,
not a watchpoint -- and an entry probe on that function names the set directly.
NOT written. The only two saves in the corpus with a non-zero Status agree with
Species != 4 on all eight players, and that is eight observations on a 1-bit predicate
that nine of the eleven saves do not exercise at all. Evaluated and reported.
Seven addresses in ghidra/addresses.d/lane-t2.json, validated to a scratch path against
the merged set (1,095 entries, no duplicate). verify/results/standalone/{report,status}
deliberately untouched: lane C3 published into them minutes before this run.
`ServerSystem::ComputeOutput` 0x00751fb0 and the whole of `ComputeOutputFromRates`
0x00751bb0, read from the instruction stream to the next function start. This is the
function lane E1 correctly identified as the real blocker on P01/P02/P03/P05/P06 after
its own chain came out 25/25 on BnkEl and did not unblock them.
The shape, and the fact everything turns on: construction points the build queue and
the ship-repair pass do not spend are redistributed over trade / terraform /
infrastructure, and the TRADE share is added to the money channel. Unspent
infrastructure points cascade into the terraform pool and unspent terraform points
cascade into money -- two hops, not one. So a colony with an empty build queue earns
the same money whichever way its sliders point, which is why the turn path's money
sits within one trade point of the projected path on this corpus.
Eleven addresses, five of them dropped as agreeing duplicates. New: the repair pass
0x00751590 (the B1 double-run side effect, and its round robin is provably a `min`),
the construction-point helper 0x00746830, the queue-demand walker 0x008251e0, the
ideal-suitability resolver 0x00745d60, and two helpers with non-standard conventions
that would be silently wrong read as thiscall -- 0x0074c6f0 takes `this` in ESI and
0x007460b0 takes the system in EBX.
Corrections in place: `income-term.md`'s "leftover science points" are leftover SHIP
CONSTRUCTION points (there is no science channel in this function), its
science-cascade bullet moves from inferred to instruction-verified, and
`output-term.md`'s 0x00751fa8 boundary is padding -- the `ret 8` is at 0x00751fa0.
Measured, with the engine change (sots-engine wip/output2 d3ee453):
turn1-state -> turn2-state 209 -> 157 closed 52 regressed 0 (was 51 / 0)
turn2-state -> turn3-state 108 -> 86 closed 22 regressed 0 (was 21 / 0)
Closed 1 per pair, regressed 0. Every prediction in the doc's section 4 held; the one
that was off is named and explained. The strongest check is not the leaf count but
the eleven-save self-check in section 5.3, where every difference between the turn
path and the projected path decomposes to the unit into the build queue's points.
The strategic AI does not search or score. Once a turn (Process Turn phase 20, 0x006cf630) it
rebuilds a candidate task list -- which families it builds at all is a switch on the player's
SPECIES, four arms, and the NPC arm builds nothing -- sorts it by a per-task-type priority, and
walks it twice calling each task's Execute(agent, pass) with pass 0 then 1.
Closed from lane AI1's open list:
* the selection loop (its item 2) and the whole ordering policy: a 33-entry priority table at
0x00691f00 plus five named overrides;
* IAITask's unnamed pure virtuals (item 1) -- seven, not eight: GetTypeId, GetTargetA/B,
Execute, IsFinished, GetTypeName, Describe;
* the order-method -> list mapping (item 5): all 27 of lane Q's lists and all six prologue
gates now have a named producer, and list 14 -- lane Q's "observed but not understood" --
is the AI's fleet order, two elements per fleet;
* g_CurrentClientIndex (item 6): a stack pointer with exactly two writers, pushed around the
whole AI turn by StrategyAIAgent::OnEvent;
* the think-time throttle (item 7): AIProcessMinTime is a trailing Sleep, not a compute
budget. Every pending AI player's turn runs back-to-back inside one Update. The clean
"all AI orders in before the human's End Turn" ordering HOLDS, and Rung B is not at risk;
* Broadcast -> OnAIPacket, read to the call -- AI1's one inferred hop is now verified.
Corrections: 31 concrete task classes, not 34; 26 order methods, not 21; seven pure virtuals,
not eight. lane-ai1.json's Broadcast and g_CurrentClientIndex entries upgraded in place.
Open and said so: slots 11/12/13 unnamed, the nine goal tasks' bodies unread, the two-pass
meaning inferred, the StrategyApp pending-AI enqueue site not found, nothing run under an
instrument. Four predictions in section 9, P1 being a ModCount prediction.
ghidra/addresses.d/lane-ai2.json: 25 entries, 1031 -> 1056, no duplicates.
- determinism oracle regenerated and byte-identical (bb4fd9ac / 978041ac)
- the four phase-23/33 draw-bearing tail callees run EVERY turn; the three inner
functions holding the draws run zero times -- the gate is inside each outer body
- CreateRaidEncounter is called (2 on one turn) and draws nothing: candidate list empty
- Zuul: 7 calls / 7 words per trade-raid Chance site, 14 not 16, as predicted
- EncounterDetect_Run receives an EMPTY record vector, so ProcessTeamRecord and
AssignContacts never run; the 2-word detection residual is in 0x007d5150's subtree
- a MinHook detour on 0x00893290 changes the game's output; bisected over six runs.
The un-instrumented game and lane Z's instrument agree, so lane Z's numbers stand
- lane AI1 insert: P2 held across two fresh processes, Rung B stays as written
`output-term.md` §6 said the verified output total did not unblock the budget
because a system's MONEY is a second chain. This is that chain, disassembled to
the next function start throughout.
The multiplier `formula-gaps.md` Q3 could not name is a three-row table the
executable BUILDS IN CODE from .rdata float literals -- no data-file key, no
GlobalConst slot, the same shape lane N found for the pop-type table.
ServerPlayer+0x36c is an unnamed, unsaved pointer to {int id; float ai[3];
float other[3]}, filled from that table by ServerPlayer::Read and selected per
player by `is-AI && !NPC`. Every corpus save carries aidf == 1, whose AI income
column is 1.1f. The record's other two columns are a fleet-maintenance DIVISOR
and a RESEARCH multiplier -- Q3 called the third a trade multiplier and it is not.
25/25 on the oracle, from 6/25. The prediction of WHERE the remaining misses were
was wrong and is written down as wrong: the twelve Zuul records were not missing
the suitability cost (every corpus colony sits at its species' ideal, so that
whole term is multiplied by zero and stays unexercised). They were missing
SpeciesDef +0x4c/+0x50, which are PER SPECIES and were carried as one global
pair -- 400 output points, 2000 money, per Zuul colony, and the observed 4400 and
5566 shortfalls fall out to the unit.
New wire fact: the Sim block's ISsp/ISsu pairs ARE server->IdealSuit[], the
float[7] CalcSuitMod indexes. The array is randomised per game by the map
generator and cross-checks against every ServerPlayer's own IdealSuit field in
all 11 saves, so the suitability cost needs no data file.
Also states plainly what this does NOT unblock: ComputeBudget's turn path takes
its per-system money from ComputeOutput with the system's OWN rate sliders, not
from ComputeMaxIncome, so P01/P02/P03/P05/P06 and the two research RNG words stay
blocked on a strictly larger function.
204 -> 158 and 103 -> 87, closed 46 and 16, regressed 0 -- the predicted table
line for line, including the 32-leaf target in full. Three further pairs the
model was never fitted to close 42, 12 and 12 with zero regressions; 128 leaves
across five pairs.
The AFlags-vs-VFlags falsification is decided on a real save rather than in a
comment: running the engine on zuul-turn23-fleet23 reproduces the frozen stamp
at the one system whose active mask is clear while its sticky and explored masks
are not.

The NVE writer 0x00756300 and its four siblings, `ltis`'s writer 0x00743ec0, the
encounter-placement routine whose unserialised field feeds Eid, the tail phase that
calls the writer, and the resolution of an indirect edge lane B5 left open --
ServerSystem primary vftable 0x00a2044c slot 7 is 0x007480b0, and it writes only a
runtime mask, so it never reaches the wire.
None of the ten collides with an address already in the DB (checked against all 714

NVE is a per-(system, player) map of {ETS = turn of sighting, Eid = encounter type
present}. Primary writer 0x00756300, called from tail phase 17 under the gate
(AFlags >> PlyrIdx) & 1 -- byte-decoded at 0x007cf7a7..0x007cf7ce, not from the
decompiler. Three further accessors named, including the intel-sharing copy that
keeps the older sighting stamp. operator[] has exactly three callers and none of
them erases, so the record is a memory, not a state.
Also names ltis's writer (driver phase 29, AFlags != 0 -> ltis = Frame), closing
half of board.md's 'TShn/ltis: NOTHING NAMES THEIR WRITER'. TShn's own gate is
still unnamed and demonstrably NOT AFlags -- Spica is the counterexample.
Resolves lane B5's flagged indirect edge: SetExploredBy's vft[0x1c] is
ServerSystem vtable slot 7 at 0x007480b0, and it writes only an unserialised
runtime mask.
Prediction committed before the engine change exists: 204 -> 158 (46 closed, 32
of them the brief's target) and 103 -> 87 (16 closed), 0 regressed, with a
falsification section naming the corpus save that separates AFlags from VFlags.

standalone_report.py regenerated from sots-engine wip/turnrecord. The reference pair does
not move by design: T36 does not commit by default, so 209 -> 204, closed 5 / regressed 0
and 108 -> 103, closed 5 / regressed 0 are unchanged. What moved in section 6 is the phase
tally, 14/44 modelled and 8 committed -> 15/44 and 9, from the A2 and D2 merges. verified
stays 0 on both tables.
t36-turnrecord.md carries the measurement the default run cannot show: with
--commit-blocked=T36 and a data root, the reference pair closes 29 leaves and regresses 7
(was 9). Two of the three census leaves close; the third is short by exactly one destroyer
on both pairs, because no phase we run builds a ship. The census model itself reproduces
480/480 archived census leaves over 11 saves with 0 mismatches.
T36 stays blocked: sav and inc on lane E1's budget, and one ship count on unmodelled
construction. A field-granular commit knob is not implementable -- the archived record is
one struct on the wire and has no hole to leave.
Coverage: 32 of 480 census leaves are nonzero anywhere in the corpus; cls1 and cls2's
platform count are unexercised, not verified.
Blocker #4 on lane Y's path to a byte-matching turn.
HOW DESIGNS PERSIST, correcting a published finding. Game::ShipDesign::Write is
0x008325e0 and makes four stream calls. The recorded address 0x008747a0 is in
NO vftable at all (lane V2's inversion), so "ShipDesign::Write makes no stream
call" was a misattribution, not a fact about the class. Game::ShipDesign
derives from Game::ShipDesignDef and inherits IStreamable second, so its writer
is reached through an adjustor thunk -- which is what the slot-indexed
serializer sweep found instead. A design persists as two serializers, base and
derived: ShipDesignDef::Write 0x00827390 emits FAIDes/DHide/DWep/DName then
exactly three DSec frames (+0x4c command, +0x24 mission, +0x74 engine),
ShipDesign::Write appends Dtc, the Dwgv flag and a conditional Dwg frame.
THREE sections, not five. The campaign's "slots 3-4 reserved and always empty"
was save_reader.py's trailing Rest("sections") sweeping Dtc and Dwgv into the
section list, and stock_designs.py decoding them as two empty sections -- rule 8
in its exact form, reader and consumer agreeing with each other and both wrong.
Two independent enumerations say three: the writer's straight-line body, and the
ctor's eh_vector_constructor_iterator(this+0x24, 0x28, 3) closing at
0x9c = sizeof(ShipDesignDef).
DWep and Dwgv are BOOLs, not ints -- byte-indistinguishable from ints at a
four-character tag, the same class of defect as ObservedTech.odet.
THE 0x400 FLAG IS `defence_platform`, read off the .shipsection parser's own bit
setter at 0x005749b7. NOT lane B5's 0x400: that one is a fleet flag, on the wire
as FtFlg. The full role-flag table is in the finding. HULL SIZE is section_class
through a three-name stricmp table (Destroyer/Cruiser/Dreadnought -> 0/1/2),
absent or unrecognised meaning 0 with a log line rather than an error. Both
words are recomputed from the data files by ShipDesign::UpdateDerivedStats
0x0087e7c0 and neither is on the wire. Corroborated by the default hull-health
table the same bit picks: 500/3000/15000 without it, 100/500/1000 with.
MEASURED: the census rebuilt from each save's own state matches the record the
game archived, 480 leaves / 0 mismatched over 11 saves and 503 designs, computed
independently in Python and in C++. COVERAGE REPORTED AS LOUDLY: only 32 of the
480 leaves are nonzero, and three of the six census leaves (both cruiser rows,
dreadnought platforms) are unexercised by every save in the corpus.
Closed 0 / regressed 0 against the standalone's divergence list, reported
separately: the census leaves live in src/app's turn record, which lane A2 holds
this cycle, so this lane evaluated and reported rather than writing.
Oracles fixed openly (rule 12): save_reader.py's Des shape, 49/49 with three
corrected tests and one added that pins "exactly three DSec" against real saves;
stock_designs.json regenerated, whose diff is only raw_slots 5->3 and dWep
int->bool across all 127 designs with every other field identical;
test_design_rules.py still 32/32 with the same ground truth.
19 addresses in ghidra/addresses.d/lane-d2.json, no collision; the generated
