| P2-B1 ComputeBudget (behavioral) | phase2 | verified | med | 75% | 2026-09-08 | LIVE + GREEN on declared regions (4,437 compares, 0 divergences; replace-mode oracle byte-identical). Corrections: out-param int[22]; researchMoneyKept gated on a research target. QUALIFIED BY THE HARNESS AUDIT: replace mode runs the ORIGINAL A SECOND TIME to harvest slots -> a real per-turn double effect (ComputeOutput repairs ships in orbit) that no region reaches - UNRESOLVED; the over-budget int at Budget+0x64 was captured only as an argument and args are never compared. Golden trace needs recapture with guards. Coverage gaps: 8 slots always 0 (expenses/aid/debt) . RECAPTURED WITH GUARDS 2026-09-08 (lane R): 4284 compared, 0 diverged, exit 0; budget_object guard 0 undeclared writes, so Budget+0x64 never took a different value (weaker than 'never written'). COVERAGE IS NARROWER THAN THE NUMBER: only 20 distinct (player, output) states in 4284 calls (4278 are the UI polling one player; the turn pass is ~8 calls), and 13 of the 22 slots are 0 on EVERY call - including 5 of the 6 declared input-boundary slots, which therefore prove nothing twice over. 8 modelled slots ever carry a value |
| P2-B2 OnTechResearched (behavioral) | phase2 | verified | high | 80% | 2026-09-08 | LIVE: 3 completions compared, 0 divergences (incl. one tech absent from the effects table = tail-only, the case an early return would have broken). float32 CONFIRMED ON THE GAME bit-for-bit (con_mod 1.0->0.899999976 = (float)(x+(double)0.1f)). Found B3's rolling effect: ServerPlayer::RollResearchEvent draws one NextFloat at the top of the callback - modelled + RNG region declared, but the branch never fired here so NOT behaviourally proven. KNOWN GAP: ours posts no events and the player event list is still undeclared, so the clean compare bounds the economy fields only and the replace/oracle pass was deliberately run on a no-completion turn (weak check) . RECAPTURED WITH GUARDS 2026-09-08 (lane R): 2 calls, 0 divergences; the player guard reports player+0x2b0 (EvNxID) on BOTH calls, so 'ours posts no events' is now measured, not assumed. RollResearchEvent branch FIRED and matched (see its row). Also caught an undeclared vector<ObservedTech> append at player+0x274. Reachable only after 5 End Turns from ref-turn2 |
| P2-B3 ProcessResearch (behavioral, RNG) | phase2 | mapped | high | 85% | 2026-09-08 | LIVE, PARTIAL PASS: 15 calls compared, 13 zero-divergence; RNG post-state matched 14/15 incl. every roll (validates MT19937 + draw mapping + odds together). 2 divergences are the declared SetResearched boundary. ORACLE FAILS by exactly one item across 40,300: an unposted EVENT_RESEARCH_OVERBUDGET - compare was blind because the event list was never a declared region. fpu_cw=0x127f => 53-bit double, x87 question SETTLED. No Zuul in the save: double roll still disassembly-only . RECAPTURED WITH GUARDS 2026-09-08 (lane R): the oracle gap is now a COMPARE DIVERGENCE - side.events.after.v.next_id orig=4 ours=3 on call 0, its only divergent field, with node[144] progress 2879->5768 and flag 1->2 both reproduced and the single RNG draw identical. 15 calls over 5 turns: 3 diverged, RNG 15/15 (better than the original 14/15 - no tech-effect draw in this session). Guards on the two completion calls map SetResearched: ConMod[0..2]/OutMod/PopMod, ResTNm, TechTree+0x20 order counter, and the undeclared otch vector |
| RNG signatures (Ghidra) | meta | verified | high | 100% | 2026-09-08 | Seed/Twist/NextFloat/NextInt verified; draw = y/(2^32-1); NextInt [0,n] inclusive; lazy twist; left@+0x9c4. RUNTIME CONFIRMED: fpu_cw=0x127f (53-bit double, round-nearest) - our next_float model is right, float_from_pc24 is an unused contingency |
| engine: game/effects | engine | verified | high | 100% | 2026-09-08 | merged: TechId enum (196 slots @10000+i), 44 ids with typed strategic effects, species flag bits, ApplyTechEffect; 254 checks |

VM left at the MAIN MENU, hooks=trace, build recap-7584bad-20260908T0615Z restored from C:\SOTS\shimdist-recap (that dist also carries shim.cfg.recap{trace,b3,b1,misc}). Lane M also left C:\SOTS\shimdist-mf + C:\SOTS\ui\mf{deploy,release}.ps1 in place - harmless, and a working template for the next lane. Windows Update DISABLED/paused on the VM. Non-holders build /srv/re-lab/build/sots-engine-, stage dist-, deploy C:\SOTS\shimdist-. GOTCHA (lane R): after schtasks /Run /TN SOTS the main menu can take >60 s - SCREENSHOT AND VERIFY before clicking, or the click path lands in Credits. GOTCHA (lane M): drive the load dialog ONE rui.ps1 CALL PER CLICK with a screenshot between - a single chained cmd.txt loses sync and silently ends up somewhere else. And the Load Game dialog does NOT pre-select Single Player on a fresh launch: the documented path really is Load Game (512,536) -> Single Player (512,290) -> OK (551,523) -> row -> OK (682,624) -> Launch (511,663). ref-turn2 row is at (400,436) |
| Zuul double-roll (behavioural) | verify | backlog | — | 0% | 2026-09-08 | CONFIRMED NEEDED: ref-turn2 has only species 0 and 2, so the double roll is verified by disassembly + host tests only. Needs one compare from a species-5 save; the check is just that left drops by 2 not 1 |

Need a save with expense sliders, a debtor and a research-aid treaty to exercise ExpenseTotal + the aid/bonus tail . CONFIRMED AND WORSE 2026-09-08 (lane R, 4284 calls): 13 of 22 slots are 0 on every call - tradeIncome, shipCarriedPop, secondaryManager, bonusIncome, systemIncomeNeg, debtInterest, construction, expenses, researchMoneyGiven, savingsGiven, tra, researchPointsGiven, trp |
| hook GetDifficultyMods | meta | backlog | — | 0% | 2026-09-08 | B1 derived the two difficulty rows from trace values (AI maintenance divisor 3, research x1.5) instead of snapshotting them; hook it properly so they stop being constants |
| section-loader compare crash | verify | backlog | — | 0% | 2026-09-08 | SectionDictionary compare crashes the engine while the identical weapon path succeeds -> fault is in re-running LoadSection, not the manifest reader. Next boundary: hook LoadSection itself. docs/M2.md has 3 ranked leads |
| P2-B4 colony + movement (behavioral) | phase2 | mapped | med | 70% | 2026-09-08 | LIVE: 36 calls compared, 0 divergences, tracecmp exit 0. Scout's headline: RNG left-delta 0 and mt hash identical on ALL 28 systems (only ProcessRebellion draws; none fired) - fpu_cw 0x127f confirmed. One real fleet move reproduced bit-for-bit; PlanFleetMovement's schedule matched. 3 prototypes + 6 helpers VERIFIED and written back to Ghidra; 22 formula corrections. THREE hook bugs found by reading the trace, not the verdict (stale args from describe_args-before-regions; StrategyServer has TWO bases 4 bytes apart; off_Fleets was a Ghidra-base number used as raw) - each would have given a clean compare that checked nothing. COVERAGE IS THIN: only 3 owned systems, 1 moving fleet, gate traffic all-zero; bats2, plague, rebellion, slaves, terraform, jumps, arrivals untested. No replace mode (input boundary). VM released: main menu, hooks=trace, build b4-fix2-20260908T0615Z . QUALIFIED 2026-09-08 by lane R: with 45 MoveFleet calls over 5 turns instead of 7 over 1, 8 of the 15 moving calls diverge by 1 ULP of position. B4's clean verdict was a ONE-SAMPLE verdict - fleet 34 (its only mover) still matches bit-for-bit; the bug appears once other fleets move. ProcessTurn recaptured at 140 calls / 0 divergences, but only ntdev (15x) and rcex (7x) ever moved: everything else was byte-identical on all 140, so the verdict bounds two counters. Guard found the AI home system's fleet vector growing every turn (the build queue emitting a ship) |
| harness gap: undeclared side-effect lists | verify | verified | high | 100% | 2026-09-08 | FIXED STRUCTURALLY (engine 3f0721f+): compile-time-required Coverage on every descriptor (a hook without one does not compile); Guard regions that catch AND localise undeclared writes (names player+0x2b0, not 'the hash moved'); replace mode now emits records; tracecmp prints coverage on every report + --strict-coverage. A hook claiming 'complete' while a guard caught an undeclared write now counts as a DIVERGENCE. Audit found 23 undeclared side effects: docs/harness-audit.md |
| RollResearchEvent draw (behavioural) | verify | verified | high | 100% | 2026-09-08 | CLOSED by lane R. On turn 6 (IND_TRKSTL, tech 10094) research_roll_pending was true going in; the original drew exactly one word (rng left 375->374, next_index 249->250) and cleared the flag, and ours reproduced both bit-for-bit on the scratch generator. 0 divergences on that call. Needs 5 End Turns from ref-turn2 to reach - the reference turn has no completion at all |
| golden-trace recapture (post-guards) | verify | verified | high | 100% | 2026-09-08 | DONE on the live game, build recap-7584bad-20260908T0615Z (NO source change needed - the audit's machinery did all of it). B3 ProcessResearch: the defect is VISIBLE - side.events.after.v.next_id orig=4 ours=3, one divergent call of 3 on the reference turn and its ONLY divergent field; bit-for-bit the EvNxID 4->3 that previously needed a 609 KB save diff. Over 5 turns 15 calls / 3 diverged, RNG matched 15/15, and the two completion calls miss TWO event ids each. B1 ComputeBudget: verdict held - 4284 compared, 0 diverged, exit 0, budget_object guard caught 0 undeclared writes (Budget+0x64 never changed value). MoveFleet: 8 of 45 diverge by 1 ULP of position (new; see its own row). First guarded captures for OnTechResearched (2 calls), ServerSystem::ProcessTurn (140 calls) and MoveFleet (45). Guards mapped SetResearched live (ConMod[0..2], OutMod, PopMod, ResTNm, TechTree+0x20 order counter) and found an UNDECLARED vector<ObservedTech> otch append at player+0x274.

| MoveFleet position rounding (1 ULP) | verify | verified | high | 100% | 2026-09-08 | CLOSED by lane M. Mechanism read off the instruction stream, not fitted: the engine's Mars_Vec3_Normalize (0x00422520, 123 callers) narrows to float32 FOUR times - sumsq = f32(x*x+y*y+z*z) (products/adds stay in 53-bit regs, only the SUM is stored), len = f32(sqrt(sumsq)), inv = f32(1.0/len) a RECIPROCAL that is MULTIPLIED through rather than three divides, and dir.c = f32(delta.c*inv); and MoveFleet stores each dest.c - pos.c BACK TO A FLOAT32 SLOT before calling it, and takes the leg distance from that same call's return value. ours did all of it in double. The position tail (f32(pos + f32(dir*move))) was already right, which is exactly why the error was a constant ABSOLUTE ~1.2e-7. Confirmed OFFLINE first (an arrival copies the destination verbatim, so calls 115/155 hand you fleet 34's and fleet 50's exact float32 destinations = 8 fully determined legs; the 5-narrowing model reproduces the ORIGINAL bit-for-bit on all 8, the old double model reproduces ours on the 3 divergent ones), then LIVE: control run 8/45 diverged exit 1, fixed run 0/45 diverged exit 0, with identical args, identical pos.before and identical ORIGINAL pos.after on all 45 calls.

Seen as an undeclared write by BOTH the ProcessResearch player guard and the OnTechResearched player guard. It is serialized ServerPlayer state and it is in NO coverage note anywhere - a third list append in the same neighbourhood as the event list. B3's replace oracle never saw it because turn 1 of ref-turn2 has no completion |
| unnamed offsets from guard hits | verify | backlog | — | 0% | 2026-09-08 | NEW (lane R). Three spans the guards report every run and no addresses.json entry names: ServerSystem+0xd8 (1 B) and ServerSystem+0x238 (4 B) - written by the AI home system on every colony turn, alongside the fleet-vector growth; StarFleet+0xdc (1 B) - written on every moving MoveFleet call, just past Speed (FPsp2 @0xd8). Cheap wins for the contract |
| waypoint types 2-5 have no coverage | verify | backlog | — | 0% | 2026-09-08 | NEW (lane M, promoted from a coverage line to its own row because it is now the biggest gap in MoveFleet). Types 2 (node line), 3 (node route), 4 (gate teleport) and 5 (probabilistic jump) have NEVER fired in any capture, and the node-line step is WRONG BY CONSTRUCTION - sim::NodeLineStep and sim::BuildStutterSegments are written and host-tested but are NOT wired into the hook, which steps every waypoint type as speed x dt. ref-turn2 structurally cannot exercise them: lane M held the VM and tried. The only mover in that save is the AI, which travels straight runs; the player that would travel a node line has DE 00 CR 00 DN 00 at its home system (screenshot verify/results/shim/mf-human-home-no-ships.png), so Move/Manage Fleets are greyed out on every turn. Needs a ship built over several turns, or - much cheaper - a PURPOSE-BUILT SAVE with a fleet already in orbit next to a node line. Same save would unblock the gate-traffic and probabilistic-jump rows. Also owed on that path: sim::Distance is still plain double, and Mars_Vec3_Length (0x004224b0) says every vector length in the engine is float32-narrowed twice, so the stutter geometry is probably 1 ULP out the same way the position update was - deliberately left alone by lane M because there is no behavioural evidence to correct it against |
| ref-turn2 has no tech completion | meta | verified | high | 100% | 2026-09-08 | TRAP for anyone writing a workload (lane R). The documented one-End-Turn recipe produces zero OnTechResearched calls - an empty log that still passes. It takes 5 End Turns (to turn 7) to reach a completion. Also: only the FIRST End Turn is reproducible - it hashed to the oracle on all four runs and its research calls reproduce docs/B3.md exactly, but from turn 4 the AI picks a different research target than B3 recorded while the point totals stay nearly identical. Treat anything past turn 1 as a run, not the run |
| B1 replace double-run | verify | backlog | — | 0% | 2026-09-08 | ComputeBudget replace mode runs the original a second time to harvest budget slots; ComputeOutput repairs ships in orbit as a side effect, so this is a real per-turn double effect on objects no region covers. Needs a design fix (harvest without re-running, or declare+revert) |
| ReVa MCP link drop (workaround) | meta | verified | high | 100% | 2026-09-08 | The ReVa MCP client link dropped mid-session while the CT111 server stayed healthy (systemd active, :8080 listening, valid key -> 200). tools/reva_call.py <tool> '<json>' calls the same server over plain HTTP (initialize -> notifications/initialized -> tools/call; replies are SSE with a leading id: line, initialize is plain JSON). Key is NEVER stored in the repo: $REVA_KEY, else ~/.claude.json, else ssh to the CT properties file. Use this whenever mcp__plugin_ReVa_ReVa__* is unavailable |
| event posting API | subsystem | mapped | high | 90% | 2026-09-08 | RECOVERED (lane E, findings/subsystems/events.md). Container: EventStorage embedded at ServerPlayer+0x29c (0x1c), EvNxID at +0x14 = player+0x2b0 — exactly the guard's byte run. Nested vector<TurnEvents{int EvTurn; vector<PlayerEvent>}>, record 0x74 B, tags EvEID EvDsc EvMsg EvImg EvLoc EvPos EvAct EvCID; layout confirmed field-by-field against turn3-state.sav, which CONTAINS the overbudget record. Entry point int __thiscall EventStorage::PostEvent(this, string BYVAL, string BYVAL, obj*, Vector3*, turn, const char* img, int act) 0x008862b0 RET 0x4c — 161 call sites in 113 functions, the whole sim's event API. B3 defect fully explained: 0x00587b97, in the completion-roll-FAILED branch under !wasDone && nowDone && owner. 3 note corrections (EvPos is FLT_MAX not inf; the save array is turn-bucketed not flat; TECHS_UNLOCKED has no parent clause). 56 entries in addresses.json; 11 prototypes + 13 labels + 12 comments + 2 structs written back to Ghidra. Engine: sots-engine branch wip/events a7348be, src/game/events + 112 checks, ctest 32/32. NOT YET WIRED INTO A HOOK — see docs/E-events.md for the proposed region/Coverage change |
| state-checksum replay harness | verify | verified | high | 90% | 2026-09-08 | Lane C: verify/state-checksum/ (tool, 38 tests, STATE_CHECKSUM.md, evidence in verify/results/state-checksum/). Whole-state digest tree; coverage is PROVED by byte-for-byte re-serialisation, not declared - the answer to empty-region-set green verdicts. Localises: the known load->re-save delta reports as exactly 5 named leaves (/Sim/players/Player[496 "Singularity"]/Status: 4 -> 0, /Summary/Checksum), and one real End Turn as 108 attributed diffs. All 10 saves STABLE + COVERED. Float policy = exact bits by default, canonical for -0.0/NaN only, tolerance deliberately not a hashing mode (it lives in --ulps on the differ); corpus has 0 NaN/-0.0/subnormals so canonical is a no-op today. Chain record/verify validated on the real turn1-3 saves. REMAINING 10%: the VM-driven replay loop is designed (§5) but UNRUN - needs the VM holder. Open question named in §3.5 with the experiment that settles it (force fpu_cw 0x027f/0x127f/0x137f across End Turn, checksum the three autosaves) |
| MoveFleet position ULP divergence | phase2 | verified | high | 100% | 2026-09-08 | DONE (lane M). First arithmetic divergence caught by BEHAVIOURAL compare rather than static reading, and it is fixed by matching the original's precision sequence rather than by fitting numbers - see the MoveFleet position rounding (1 ULP) row for the mechanism. Live 8 -> 0 on the same 45 calls, control run included so the before/after is this lane's own measurement. COVERAGE IS UNCHANGED AND STILL THIN: 15 of 45 calls move and all 15 are the same straight-run waypoint type. Waypoint types 2-5 were ATTEMPTED and could NOT be reached - the only player that would travel a node line has DE 00 CR 00 DN 00 at its home system on this save, so its Move/Manage Fleets buttons are greyed out every turn and there is literally nothing to send along the node lines the map draws. Reaching them needs a ship BUILT over several turns, or (cheaper) a purpose-built save that starts with a fleet in orbit beside a node line. The node-line step is still wrong by construction: NodeLineStep/BuildStutterSegments exist and are unit-tested but are not wired into the hook |
| ObservedTech append (undeclared) | verify | backlog | — | 0% | 2026-09-08 | Lane R's guards caught a vector append at player+0x274 during SetResearched. It is SERIALIZED state and appears in NO coverage note anywhere - found only because guards localise rather than just flag a moved hash. Needs a declared region + a model in ours |
| fpu_cw sensitivity experiment | verify | backlog | — | 0% | 2026-09-08 | QUEUED FOR VM140 (lane M holds it). Lane C cannot tell whether any turn-pipeline value actually DEPENDS on x87 intermediate precision - every save on this host was made at fpu_cw=0x127f, so "the x64/SSE port must match bit-for-bit" is currently POLICY, not a measured requirement. Experiment: End Turn from ref-turn2.sav 3x with the shim forcing fpu_cw to 0x027f / 0x127f / 0x137f, then state_checksum the three autosaves. All equal => no double-rounding budget needed, closes STATE_CHECKSUM 3.5. Different => the diff IS the answer, naming every precision-sensitive field |
| Summary.Checksum algorithm | objects | blocked | — | 0% | 2026-09-08 | Lane C RULED OUT two candidates so nobody repeats them: NOT a byte sum over the inflated stream, NOT a sum over the int leaves. Each is consistent with the -16 re-save delta but leaves no constant residual across turns |
| event posting in ours | phase2 | in-progress | — | 0% | 2026-09-08 | Lane P: make ours actually post events so ProcessResearch's side.events.after.v.next_id 4->3 divergence closes. Converts harness-audit row 1 from known-defect to checked, and unbounds B2/B3 whose clean compares currently cover economy fields only |
LAB RULE: no git add -A in sots-re while lanes run |
meta | verified | high | 100% | 2026-09-08 | MY error, caught by lane M: an integrator git add -A in the SHARED sots-re clone swept a running lane's in-progress files into commit 9d385a7 mid-run (remainder landed in f5b37c2). Nothing was lost, but authorship and atomicity were. RULE: while any lane is live, the integrator stages sots-re by explicit PATH only (git add campaign/board.md campaign/DASHBOARD.md), never -A. Lanes own their own subtrees. sots-engine is unaffected - lanes work in per-lane worktrees there, which is exactly why that repo has not had this problem |
| MoveFleet waypoint types 2-5 | verify | backlog | — | 0% | 2026-09-08 | Still ZERO behavioural coverage after lane M. Not for lack of trying: the only mover in ref-turn2 is the AI (straight runs only), and the player that would travel a node line has DE/CR/DN all 00 at its home system, so Move/Manage Fleets are greyed out every turn - there is nothing to send along the node lines the map draws. Needs a ship built over several turns or a purpose-built save. The type-2 node-line step is still WRONG BY CONSTRUCTION (B4). Also: sim::Distance deliberately left in double (only stutter geometry uses it); Mars_Vec3_Length says it is probably 1 ULP out the same way, but there is zero behavioural evidence to correct it against - do not "fix" it blind |
