The hypothesis under test was the lockstep discipline: that each run of an AI client consumes a
fixed number of draws regardless of the path it takes, so a reimplementation could keep the
generator aligned with the right COUNT and order of draws while getting the decisions wrong.
It is false, and it fails at four scopes. Measured with a new bracket on
StrategyClient::OnResumePlaying over the per-client generator at +0x134, six runs across VM140 and
VM145, five fresh processes; every unpinned run's autosaves are byte-identical to the published
oracle, so the instrument is behaviour-neutral (rules 19 and 26 both discharged).
across clients turn2->turn3: 3 / 0 / 0 words for AI players 32 / 496 / 512; human 0
across turns client 32: 3 words on turn 2, 7 on turn 1
across processes client 512 makes ONE cl_RandRange call on turn 1 -- the research-target
tie-break at 0x006a8495, phase 18 -- and it cost 1 word in one process and
3 in another, because RNG_NextInt is an unbounded rejection loop
per site RNG_Chance costs ZERO words at p<=0 and p>=1
Twenty-one live draw sites in an AI turn, in twelve functions (plus two provably dead ones); two
fired on the reference turn, three on turn 1. Only three are unconditional, and all three only
given that their enclosing function was called. Six of client 32's seven turn-1 words come from
the ship-design composer 0x006ad700, which is also where the only loop-carried draw lives.
Also: cl_RandFloat 0x00579c70, a third cl_* RNG facade, found twice independently. It reaches
RNG_NextFloat by a TAIL JUMP, so no rel32 sweep for the entry points can see it -- which is why
ai-turn-logic.md 5's 'zero NextFloat calls from the AI module' reads as true and is not. All 29
call sites of the three facades are inside the AI band: the cl_* RNG facade is AI-only surface.
Positives for the engine: the AI draws from nothing but its own client's generator (foreign_words
0 on every bracket), the human client draws nothing at all, and the per-turn cost is single digits.
Rung B is unaffected. Rung C needs the decisions.
C5b confirms C5a: pinning the AI client seeds to an earlier run's makes the creation
turn reproducible. Three processes, each drawing its own three seeds, all pinned to
C3's, all producing d59bb9f2... with identical gates (including player 512's target
282, the value no other run has produced) and identical element records.
The only word that differs anywhere across the three is word 3 of list 23's unnamed
Population body. Three runs with byte-identical autosaves cannot differ in a word the
applier reads, so that word is noise -- localised using the pinned pair as an
instrument, which is what a control on a k>1 workload is for.
Two agreeing is a 1/k coincidence; three is 1/k^2.

Canonical pair turn2->turn3: the complete block set, the three heap payloads no
previous capture could read (route [272], list-10 [1728], the 24-byte Population
body), the three AI client seeds, and both output autosaves -- byte-identical to the
published oracle AND to this lane's own hooks=off control, so the stream and the save
come from the same run and the instrument did not change the turn it recorded.
Creation turn turn1->turn2: three runs. Pinning the AI client seeds to the values an
earlier run observed made a DIFFERENT process reproduce that run's block -- including
the research pick that varies -- and its autosave byte for byte. The workload three
lanes could not reproduce is reproducible given the seeds.
Two corrections to lane L4's list-23 reading (no trailing int; the body is not
turn-dependent) and one to my own list-5 record, the latter found by lane RB while
consuming this capture.
Format: JSON (raw words are ground truth, decoded is a typing) plus lane RB's own .tcb
grammar with the heap payloads filled in, so RB's reader consumes it unchanged.

CB's VM146 capture goes through the JSON->tcb adapter and the replayer unchanged and reproduces
this lane's canonical result from a separate run on a different guest: 108 -> 62, closed 46,
regressed 0, ModCount 24. It carries the first AI seeds any capture has held (32/496/512), and
its deep dump closes two gap rows: list 8's route is [272] and list 10's vector is [1728], a
ship the input save already contains.
Replaying a turn's commands against a different board charges the counter happily and produces
a confidently wrong number, because the blocks name player ids that exist in both. The converter
now records the input save and sots_turn warns when they disagree.
sots_turn --turn-commands puts /Sim/ModCount on the original's 24 with zero residual, closing
the one leaf that has been unreachable from a save all campaign. Canonical pair 108 -> 62,
closed 46, regressed 0, fresh build directory.
The .tcb capture format (line-oriented, parser-free, '?' for a field the instrument could not
read, per-client AI seeds), a converter from lane L4's shim dump, and an adapter from lane CB's
JSON capture -- CB's stays the capture of record, .tcb stays the engine's input, and the two
paths produce byte-identical replays.
A falsified prediction paid for itself: the first run regressed two leaves because list 5's
element is decoded in MEMORY order, and the memory order of the rates frame is NOT its wire
order. Memory member 1 is wire member SRsc; six members unread. Lane CB's decoder has the same
defect and should drop its list-5 record.
Two new addresses (the second and third gate-loop heads) in ghidra/addresses.d/lane-rb.json.
QEMU's command line contains ifname=tap141i0, so pgrep -f on the tap name matches
the VM alongside the capture. Stopping the tcpdump that way SIGTERM'd VM141.
Nothing was lost (all artefacts were already off the guest and it restarted with
a clean volume) but it is a plug-pull on an exclusively-held guest. Use
pgrep -x tcpdump.
Two processes, same workload. Phase 18 tries three producers; only ONE of the
three AI players reaches the candidate walk at all, which is why the other two
are stable across every run of both lanes -- different code path, not better luck.
For that player the candidate stream is ONE entry, {2, 12}, in BOTH runs -- a
category, not a tech. So arrival order in the candidate vector is not the
mechanism (a vector of one has no order), and the three-arm fallback never ran
(both probes zero, both runs). The variation is inside the resolver that turns a
category into a tech, and it produced XNC_TrnsMorr2 (techId 288) in one process
and XNC_TrnsHum2 (techId 282) in the next.
k is nameable from the shipped tech data: XNC_ROOT allows six tier-1 techs at an
identical 2000 RP, one per species, each allowing exactly one tier-2 successor --
the six XNC_Trns<Species>2. Four of the six have been observed across six runs
between lanes L4 and L5, and their costs differ (13000-30000), so the resolver is
not ranking by cost; it takes whichever member of the available set it reaches
first.
Bonus rule-19 result: run R2's autosave is byte-identical to the hooks=off control
of the same workload. Twenty detours installed, same tiebreak, same bytes -- the
only free variable in the whole turn is the tiebreak itself.
Still open and flagged: BIO_GnMod, the one observed value outside that family.
Seven more addresses in ghidra/addresses.d/lane-l4.json; the eighth collided with
lane AI4's cl_SetResearchTarget and was dropped with the agreement recorded.
Two results from the same VM session, both of which needed a workload the
corpus cannot supply.
CDiff, played forward. ref-turn2 loaded and 49 End Turns driven through the UI
helper to frame 51, with the entry hook emitting one record per turn:
50 calls, frames 2..51, EXACTLY TWO STORES
frame 2 -1 -> 0
frame 50 0 -> 1 <- the modelled tier transition, at the modelled frame
and 47 turns between them on which the writer ran and wrote NOTHING
predict_path was computed at entry from the transcribed threshold table on all
fifty turns and agreed with the cdiff region on every one. Frame >= 100 is still
a code read and is not claimed as a measurement.
The AI seed probe (asked for by the coordinator, ranked above CDiff). Hooks on
Mars::RNG::Seed and StrategyApp::RunAI, two launches from turn1-state, load
only. Every AI client seed differs between processes -- net 32, 496 and 512 all
move -- while the record structure is identical and one Seed call with seed=0
produces a byte-identical state in both runs.
So the turn1-state -> turn2 nondeterminism is a SEED effect, not the ordering
effect predicted, and the 'one of three varies' observation is explained by two
of the three empires having a research pick that is robust to the stream. This
falsifies lane AI1's 'every draw from the static generator returns 0', which
that lane had explicitly flagged as arithmetic rather than measurement.
Where the seed comes from is NOT established; the finding names the one hook
that would settle it and the six values it must reproduce.
VM140 left as found: the 8-file save set with its oracle bytes intact.

findings/subsystems/ai-order-capture.md -- two workloads on VM145, every submitted
TurnCommands block dumped at the batch applier, plus sixteen pass-attributed entry
probes on the task bodies and the emission gates.
Headline: our emission model reproduces both real blocks exactly, list for list and
element for element, and both turns land on the measured ModCount of 12. What it did
not have: a list-23 element on every AI turn (the first element ever observed in the
free half of the cost table, and it really is free), client-allocated ids travelling
inside the commands (design 18, fleet 34 -- neither in the input save), and build,
rates and population all naming the same home system.
Two predictions falsified, both usefully: the batch is n = playerCount = 8 with the
four monster factions holding untouched slots, not n = 4; and the fleet order names
the fleet the client has ALREADY created, not the one in the save.
AITRaid's pass-0 question stays open and now says why -- the task never ran on either
board, so the list-16 zero is 'never entered', not 'entered and silent'.
Rule 19: the ref-turn2 control passed byte-identical to the published oracle with all
seventeen detours installed. Separately, the turn-1 workload is NOT reproducible --
three runs, three autosaves, differing in exactly one field: the research target of
the AI player that owns nothing.
ghidra/addresses.d/lane-l4.json: 9 entries (8 IAITask::Execute bodies + the list-16
order method). Raw logs and the two divergent autosaves in verify/results/shim/aiorders/.
Lane SV recovered the script-object subsystem statically and predicted that
SVSOSwarmQueen::RegisterHives takes one strategic-generator word per new hive
inside StrategyServer::BeginProcessTurn, which runs inside lane Z's autosave
bracket and outside both turn drivers. Nothing had ever been hooked in that
interval. Measured on VM140, and it is right.
turn 1 -> 2 (hives created) BeginProcessTurn 2 ProcessTurn 20 residual 2
turn 2 -> 3 (hives exist) BeginProcessTurn 0 ProcessTurn 19 residual 0
Two instruments that share no code path agree: the region ledger reads
170 -> 172 across RegisterHives, and the return-address draw-site table gains a
row at 0x00527714 (NextInt, 2 calls / 2 words) which is absent on the next turn.
The draws produce NextQ 30/28, TickHives' slip takes them to 31/29 -- exactly
turn2-state.sav -- and the next turn's slip gives 32/30, exactly turn3-state.sav.
So tail-rng-ledger.md's "all of it inside ProcessTurn, residual exactly zero" is
correct for every turn it measured and false as a statement about the code. The
interval a standalone must reproduce starts at BeginProcessTurn.
Also closed or corrected:
* LO/HI read live rather than fitted: NextQ = frame + 20 + NextInt(10),
inclusive; the TickHives gates are 10 (a frame floor), 5 and 3, so no queen can
spawn before frame 11 on any save.
* CDiff's threshold scan re-read independently: the tier can only ever be 0 or 1,
and "entered and stored nothing" was observed live and distinguished from
"did not run" (method rule 20).
* SnLv measured for the first time: Spica reads AFlags 0 with SnLv 0x200, so the
sensor branch is what refreshes it -- nvo-tshn-visible-owner.md §6 goes [H] to
[V]. ComputeContactLevel's documented "else 1" names one of four return tails;
the observed non-visible level is 2.
* Rule 19: the oracle reproduced byte for byte with all five new detours live,
and again with four watchpoints armed on top.
* turn1-state -> turn2 is not deterministic (lane L5 owns this). Two more runs
here make it four distinct outcomes over six runs, including two DIFFERENT
hooks=off results, and the strategic generator is provably not what varies.

Four float constants in ComputeBudget have a width a C++ port gets wrong by
default, and the corpus exercises the boundary of exactly one. That one is now
measured against the running game, with a control build that must fail and does.
savings interest (double)0.01f boundary: treasury a multiple of 100 IN CORPUS
debt interest (double)0.15f boundary: a negative treasury not in corpus
research yield (double)0.85f boundary: research money mult of 40k not in corpus
the three ResMod summed in f32 boundary: two of three non-zero not in corpus
Three constants sitting beside those, in the same expressions, are EXACT doubles
and must not be "corrected" -- so "widen every literal" is its own defect and the
only safe procedure is to read each operand. Same pattern elsewhere in the chain:
ComputeOutputFromRates multiplies by an exact 1.5 then a widened 1.2f two
instructions later, and NormaliseOutputRates holds 1e-4 at BOTH widths.
Live result (VM146, turn1-state.sav, three runs): the game pays 499 interest on a
treasury of 50,000 and 380 on 38,100; the exact decimals pay 500 and 381. Every
divergence in the control build lands on a multiple of 100 and nothing else
diverges at all. Coverage stated as distinct states, not calls: 5 distinct
treasuries, 2 on the boundary -- against the earlier green run's 20 distinct
states, none on a boundary.
BANKRUPTCY_PROTECTION_LIMIT_FACTOR read live: 3.29999995 = (float)3.3. Its file
image is zero because the loader fills it at run time, so lane PL-3 could read the
width and had to assume the value. The assumption was right and is now measured.
Falsified: the difficulty-mods record does not sit inline at ServerPlayer+0x36c;
that field is a heap pointer on all eight players. Recorded as a hypothesis with
the measurement, not as a fact.
Second finding, from the rule-19 control: turn1-state -> turn2 is NOT a
deterministic pair. Three runs gave three post-turn autosaves differing in exactly
four leaves -- one Singularity shadow empire's research pick and the derived
checksum. Two of the three runs carried identical hooks, and the un-instrumented
run was a third value, so this is the game and not the instrument. The
determinism oracle stands for ref-turn2 -> turn3 and does not generalise to its
neighbour; no lane should use this pair as a byte-match oracle.
The lab went from one Windows guest to five and there was no way to see what
they were all doing without issuing a QEMU screendump per guest by hand.
- tools/vmwatch.py: always-on HTTP service serving an auto-refreshing wall of
live guest screens. Runs on spicy as vmwatch.service; browse it at
http://192.168.3.201:8140/. Click a tile for that guest full size. Guests are
discovered from /etc/pve/qemu-server by matching sots-re, so clones appear and
vanish on their own. A stopped, paused or unreachable guest gets a labelled
placeholder tile carrying the monitor's own error, never a broken image or a
500. Python 3 stdlib only.
- tools/vmwatch-install.sh: install/update/uninstall the unit on the host.
- tools/vmshot.py: one-shot contact sheet, and --one <id> for a full-size grab.
Pulls frames from the vmwatch service when it is up (0.5s) and falls back to
ssh + qm monitor when it is not (4s).
- guides/lab-screen-wall.md: how to use both, and why.
Capture goes over each guest's QMP socket rather than forking qm: qm is a Perl
program, and one fork per guest per tick cost ~90% of a host core and a 728 MB
cgroup peak. Direct QMP is 0.33 CPU-seconds per 88s and 23 MB RSS. QEMU 11 here
dumps PNG natively; the fallback PPM encoder was verified pixel-identical to
QEMU's own on a real framebuffer.
Read-only throughout: screendump does not perturb the guest (method-rule 19),
so reading VM 140's screen is not an experiment and does not take its lock.
Lane W recovered what the type is; this is what moves it. Nothing in the turn calls a
method on a child script object directly. A driver notifies the root with an integer event
id, the root fans the delivery out to every child, and each delivery is a generic handler
plus one event-specific vtable slot chosen from a 33-entry jump table at 0x007a6480. That
table is what proves the hand-written pairs lane K read in the tail are event deliveries
and not ad-hoc calls, and five of its rows are not in slot order.
Six deliveries in a turn, from five functions, with the ids they send. Three handlers
write the eight leaves that diverged: the slavers' difficulty tier (a three-record stack
table against the frame, and at frame >= 100 the scan runs off the end and stores nothing,
so the tier can never reach 2), the refugees' one-shot latch at turn begin, and the swarm
queen's hives -- registered on the systems whose EggScio equals the SWARM's scenario tag,
which the queen's constructor stores at +0x4 while its own encounter id sits at +0x8.
The hive target turn slips forward by one every turn the spawn gates fail. That single
`inc` is the whole explanation of a field that reads 31 after turn 1 and 32 after turn 2,
which no re-roll can produce on two hives at once.
Corrects combat-done-tail.md: the tail has a FOURTH script-hook site, at 0x007d9820, and
it sends event 0x1c -- the same id ProcessTurn sends, which lane K attributed to that
driver alone.
Two leaves stay blocked, and not on a workload: the refugees' design id needs handle
allocation and data-file instantiation, and the hive target turn needs one MT draw plus
two config constants behind pointers no reference initialises in a form this lane could
follow. Fitting them from a single two-hive observation would have been fitting, not
derivation, so it was not done.
An RNG claim for the next lane to falsify cheaply: lane Z's "residual outside the two turn
drivers is exactly zero" was measured on turns where the hives already existed. Hive
creation draws inside BeginProcessTurn, outside both drivers and before either.
13 addresses in ghidra/addresses.d/lane-sv.json; validated to a scratch path, merges to
1,204 with no duplicate name. A fourteenth was dropped: this lane reached 0x004271c0
independently and would have filed it as RNG_NextIntInclusive, but addresses.json already
carries it as RNG_NextInt with the same convention and four lanes depend on that name. The
merger only detects duplicate NAMES, so a second name for one address would have merged
silently and forked the vocabulary for the campaign's most-used RNG primitive.
TShn is refreshed to Frame for every (system, player) that satisfies ServerSystem::IsKnownTo
0x00746390 -- IsVisibleTo OR (2-bit sensor contact at ServerSystem+0x24 AND CCC_AdvSens). Not
AFlags alone, which is why lane E3 could not fit it. The writer chain was confirmed live, frame by
frame, from a hardware watchpoint on Spica's NVO node; the refresh runs twice per End Turn (driver
phase 24 and combat-done phase 25).
Also: the trade and spy containers read out of a live game for the first time (both empty, zero
traps -- the workload confirmation two lanes lacked); Player.Status's predicate named as
ReqCL != 0 && Elim == 0, with Species != 4 shown to be a corpus coincidence; and all ten command
ModCount handlers named, two of them only reachable on a turn-1 workload.
Corrects objects/layouts.md's ServerSystem PID@0x274 row and closes system-visibility-record.md 7.
Runs: build w3tshn-bb81d3d-20260908T2007Z, configs shim.cfg.w3tshn / w3mod / w3control.
Rule 19 control passed -- the armed run reproduced the determinism oracle byte for byte.
findings/subsystems/players-residual.md is the deliverable: every one of the 54
leaves on the reference pair and the 24 on pair 2 attributed to a named
mechanism, with the rung split. 53 of 54 are pass-through -- the block is
unmodelled, not mismodelled, and only player 32's Sav is a number we compute and
get wrong.
Three corrections to the record:
- T31's self-check compared its post-turn result against the pre-turn stored
value, so its 6-of-8 covered only the players whose limit never moves.
- the AI difficulty column IS recoverable from the save, by recomputing BnkEl
under both columns against the value the save carries; 1 AI + 1 non-AI on all
eleven corpus saves.
- BANKRUPTCY_PROTECTION_LIMIT_FACTOR is read fmul dword ptr, so it is a float32
in the image; the decimal disagrees at every max income divisible by ten and
the corpus' seven records land where the two agree (rule 23). formula-gaps Q1
addendum + ghidra/addresses.d/lane-pl.json (3 data entries, fragment validated
to a scratch path, no duplicate names).
verify/results/standalone/{status.json,report.txt} refreshed from a build of main
aabd8a3: the committed copy was stale at 131/55, the real number is 128/54.
T34 RecordObservedDesigns is now readable off the corpus and is NOT an intel
pass: a design's creator registers the design in its own odes, its weapons in
owep, and re-stamps otnL on its techs in otch -- odes on build, otch on creation.
Both are hypotheses until a save exists where a player observes someone else's
design.
Status stays open and is flagged as NOT identifiable: eighteen fields of the
player record split the roster the same way and only two saves carry a non-zero
value. The probe is an entry hook on W2's writer.
Joins the emission side (lanes AI1-AI3) to the counting side (A2, W2). Three
results.
The cost of applying a command is a property of its list, and the boundary is
sharp: lists 1-16 each advance ModCount once per element, lists 17-27 never do.
Four of the six prologue gates bump, one is free, and the sixth has no applier
anywhere in the application path -- its cost is unknown, not zero. The batch
applies the twenty-seven lists in a fixed order that is neither list nor offset
order, with the six gates split across three separate per-player loops at three
different points, and four of the sixteen bumps inlined into the batch rather
than living in a handler, which is why a call-graph sweep under-counts them.
Lane W2's four unnamed handler EIPs are named, and so are its two inlined ones,
and the ten measured command bumps then decompose with zero residual. Four of the
ten are the research-rate gate, one per submitted block, and one of those four is
the human's. Two are list 14, on a turn that moved exactly one fleet -- which
confirms lane AI2's P1 (an AI fleet order deposits two fleet-task elements where
the interface deposits one) from the counter side, at no VM cost.
The reference game is not what the record says. ref-turn2.sav IS turn2-state.sav;
there are THREE AI players, not one, and the two dormant ones do run -- all three
set a research rate and picked a research target on turn 1; and the four
monster-faction players submit no command block at all, which is the first direct
evidence that they have no client rather than an empty task list.
Prediction committed for turn1-state: the same 12, out of a different set of
commands -- 4 rate gates, 3 research targets, and three orders from the one AI
with an empire, which are predicted to be a new design, a build order and a
system-rates command, with NO fleet order on turn 1. The trap multiset it
predicts contains two EIPs W2 has never seen and omits three it did, so it is
cheap to falsify: one save swap on W2's unchanged watchpoint module.
Also: phase 2 of the AI's turn is Hiver-only (a fifth cross-check on the species
reading, and the reason one prologue gate has never been observed set), phases
29-33 are dead because the submit latches the client before it builds the send
buffer, and cl_SetResearchTarget is AI-only surface with exactly one caller.
14 addresses in ghidra/addresses.d/lane-ai4.json; validated to a scratch path,
1,138 -> 1,152, no duplicate names.
findings/subsystems/population-growth.md -- ServerSystem::GrowCivilianPops
0x00754220 read byte for byte, its whole chain, and Ship::RepairCost
0x00815180.
The headline is a correction to the brief's premise. The pass is NOT gated
on imperial carrying capacity. The whole system's civilian delta is clamped
to 20,000,000 -- POPTYPE[1]+0x08, an int64 literal in the executable -- and
on both reference pairs that clamp decides the value: the uncapped delta is
7.5x it and the capacity headroom 25x it. The imperial capacity is pinned
at exactly Size x 1e8 from the corpus alone, by two independent behaviours
of one colony across three turns, with no data files.
Two boundary corrections, both of the rule-17 shape. GrowCivilianPops is a
loop over group types whose back edge lies outside every decompiler `if`,
so it reads as straight-line code if you stop at the first `ret`; its real
end is 0x00754b59. MaxPopGeneric ends at 0x0074a6cd, so the 0x0074a6d0 that
lanes N and E1 both cite for the capacity-surplus pair is a different
function.
A table correction with teeth: InitPopTypeTable never writes the group
ceiling at +0x28/+0x2c. The CRT static initialiser at 0x009abe20 does, to
INT64_MAX, and nothing else touches it -- so the clamp that reads it is
always a no-op. A reader who opens only the obvious initialiser sees zero
there and would cap every carrying capacity in the game at nothing.
Lane N's whole table is otherwise reproduced independently from the
six-register fxch rotation.
output-turn-path.md: out[6] is NOT the ship-repair demand. 0x007460b0 sums
0x0081f8c0, which gates on the design's carried-population bit and computes
GroupIncome over the ship's own Population -- so it is the income of
population carried in slaver and colony hulls, a slot the engine already
had under a name nobody had connected to it. Corrected in place, with
lane-c3.json's three unread stubs superseded by lane-g3.json's read entries.
Ship::RepairCost is unexercised on the corpus and that is a measurement,
not an absence (rule 20): the independent colony keeps a ten-ship fleet in
orbit over Koa'Vo on both reference pairs and its Sav closes exactly with
the demand taken as zero, which it could not do if any hull had a cost.
Engine side: sots-engine wip/growth ed6602e -- reference pair 78 -> 81
closed, 0 regressed; pair 2 36 -> 39 closed, 0 regressed.
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.
