WHY layouts.json was the wrong input: `build()` sorts fields by `off_abs` (**89 of 386 classes** have offset order != write order) and merges duplicate offsets into `alt_tags` (that IS the JewelsOfTheCrown double-tag trap). The table is a SPEC, not a program - the recovery is a linear pass so it cannot see `Write`'s branches and lists conditional fields (StarShip `BQ2`/`hbq`) unconditionally, and flattens container loops; a codec driven off it desynchronises. So hand-written `io()` stays the codec and a new `SchemaProbe` archive + `test_wire_schema.cpp` CHECK it: **56 shapes bound, 657 items matched, 0 mismatches**. FOUND 4 REAL DEFECTS present in BOTH `save_reader.py` and the engine, invisible to any round-trip test: `SystemParams` field 1 is a **string** not an int (empty string == 4 zero bytes == int 0, so it round-tripped by luck; a named planet would have desynced both readers); `ObservedTech/ObservedWeapon.odet` is a **bool** not an int (byte-safe only because a 4-char tag makes bool and int items both 12 bytes); `SpeciesRatios.nv` and `ShipRecords.srbd` are **counts**, not fields. TWO TRAPS RESOLVED: `ServerTradeManager`'s no-op Read/Write is real but the call is **virtual** - `ServerTradeManagerImpl` has the real serializer (`NumTradeSectors`/`TradeID`/`Trade`/`SctSize`), same shape resolves `IServerSpyManager` -> `ServerSpyManager`; general rule: **when an interface's serializer is the inherited stub, look for the concrete `*Impl`**. `ShipDesign::Write` really does make no stream call, but `ShipDesignDef::Section` is recovered so most of `Des` is typeable anyway. COVERAGE, measured by a new `CoverageArchive` that separates items a field NAMES from items a `Node` merely CARRIES (a byte-identical round trip is not a coverage claim): **37.9% -> 97.1%** typed on turn1 (97.2/97.2/97.6 on the others), round trip still byte-identical on all 4 saves. Typed this round: `TechTree` (both NumTechs sections - the 2nd is per-tech state, field list from `SpyReportTechTree` which streams the same record), `Events` (3 nesting levels), `ShipRecs`, `sprjs`, `civr`, `comms`, `spy2`, `spymgr`, `aid`, `Ojvs`, `AIEnf`, `FNG`, `trdmgr`, `Des` sections + gun banks. STILL OPAQUE: `CD` custom data 744 items (TurnCommands_v5 is a no-orders snapshot - **needs a save with issued turn commands**), `SvSctOb` 147 (8 EncObj variants), `DOpts` 94 (`read_elem` has no std::string branch), `spies2` 56, `RNG` 2 (correctly opaque).

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` append at player+0x274.

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 | . **LANE V 2026-09-08 (build `eventlive-dd38117-20260908T0916Z`): the events divergence is CLOSED on the reference turn** - 3 calls, 3 compared, **0 diverged, exit 0**. Over 5 turns 15 calls / **2** diverged (was 3), both short by exactly 1 `next_id` = the unmodelled `EVENT_TECHS_UNLOCKED`. **CORRECTION to lane R's 'RNG 15/15': that was WORKLOAD LUCK, not a property.** On lane V's call 9 the completed tech had `research_roll_pending` set, so the original drew one word `ours` did not (`left` 374 vs 375, `next_index` 250 vs 249) - the `OnTechResearched` callback draw, a DECLARED out-of-scope boundary (P-events-wiring §3 says so in as many words). Honest statement: the `rng` region reproduces bit-for-bit on every call that does not complete a roll-triggering tech, and is short by exactly one draw on every call that does. Also live: `sizeof(ObservedTech)` = **44**, measured twice (`observed_techs.bytes` 440->484 and 484->528).

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) GOTCHA (lane F, confirms lane R): the >60 s startup is REAL and cost a whole wasted run — do not sleep-and-click, **verify the main menu from a screenshot** (`verify/fpu-cw/` run scripts poll a screenshot until the Load Game / Exit buttons are bright red; 3 probes ≈ 25 s was typical). TIP (lane F): reset `SavedGames\` to a fixed file set before every run — the Load dialog row positions depend on how many files are listed, so a constant set means the click path never has to be re-derived (with the 4-file set ref-turn2 sits at (400,348), not (400,436)). PowerShell over SSH mangles quoting badly: send snippets base64 as `powershell -EncodedCommand`, or use `-ExecutionPolicy Bypass -File`. Lane F left `C:\SOTS\shimdist-fpu` + `C:\SOTS\ui\f{deploy,grab,fpu}.ps1` + `C:\SOTS\ui\preF\` (the pre-lane-F SavedGames snapshot, restored) in place. VM RESTORED: recap build `recap-7584bad-20260908T0615Z`, `hooks=trace`, SavedGames back to the 7-file pre-F set, main menu verified by screenshot. GOTCHA (lane V, third confirmation): the >60 s startup is REAL - the Kerberos intro was still on screen at t+30 s and the main menu appeared at ~t+70 s. GOTCHA (lane V): `type ` via the click helper did **NOT** register in the game's text fields this session (neither the Create Game name nor the Save Game file name took SendKeys); the workaround is to accept the default name and **rename the `.sav` on disk** - the Load dialog lists files by FILENAME. SAVEDGAMES IS NOW **8 FILES**: the pre-existing 7 plus `zuul-turn5.sav` (a species-5 save, see the Zuul row). Row positions are UNCHANGED for existing lanes because `zuul-turn5` sorts last: **ref-turn2 is still (400,436)**, zuul-turn5 is the new row 8 at (400,465), rows 29 px apart from y=262 - verified by screenshot `verify/results/shim/eventlive/load-dialog-8files.png`. The three autosaves now belong to the Zuul game. Lane V left `C:\SOTS\shimdist-v` + `C:\SOTS\ui\v{deploy,release,click}.ps1`.

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).

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.

So the port must hold intermediates at 53 bits (never compute a chain in `float`) and use round-to-nearest — both SSE defaults, now measured. **THE BRIEFED TRIPLE WAS UNDER-POWERED: 0x027f is 53-bit (differs from 0x127f only in bit 12, infinity control, ignored since the 387) and 0x137f is 64-bit, not a rounding change** — run as written, all three come back identical and would have 'proved' something false.

Trigger IS pinned (SetResearched's sweep sets state=2 + stamps turnAvailable sticky at -1; tail loop collects state==2 && turnAvailable==currentTurn) but evaluating it needs the unlock cascade ours deliberately does not run. The driver takes the unlock list as an INPUT and is handed nullptr ("no list") - deliberately distinct from an empty list ("computed, empty"). PREDICTED RESIDUAL: next_id short by exactly 1 on every completion call. Posting it "whenever something completed" would score on this save and be WRONG the first time a completion unlocks nothing - the exact false-pass shape this project keeps catching **CLOSED by lane U 2026-09-08 — by running the cascade, not by posting on completion.** `sots-engine src/game/sim/techgraph.{h,cpp}` implements `PrereqsMet` (0x0057d8e0, AND of ORs; zero groups = TRUE, an EMPTY group = FALSE), `SetResearched` (0x00581e10: stamps, child-cost sweep with a SIGNED min against an INT_MAX sentinel, sticky `turnAvailable`, zero-cost recursion) and the tail collector (0x00587cc3).

Independent BEHAVIOURAL confirmation of a purely static pin (lane X's three proofs + lane D's magic-divide inversion). Static and dynamic now agree on this struct from four directions | | CORRECTION: lane R's "RNG matched 15/15" was workload luck | verify | verified | high | 100% | 2026-09-08 | Lane V found rng diverges on call 9 (orig left 374/next_index 250, ours 375/249) = the RollResearchEvent draw in OnTechResearched, a boundary B3 and P-events-wiring 3 both declared out of scope. HONEST STATEMENT: ProcessResearch's rng matches on every call that does NOT complete a roll-triggering tech, and is short by one draw on every call that DOES. Lane R's 15/15 was a property of that workload, not of the model - exactly the kind of claim that survives only until the workload changes. The two "new" guard spans (player+0x196, player+0x3b4) are already-named fields (design-mask B, ResErrRoll) seen from the caller **EXPLAINED by lane U 2026-09-08, and it is stronger than "workload luck".** The draw is now MODELLED (`ServerPlayer::OnTechResearched` head: `if (ResT == def) { if (ResearchRollPending) RollResearchEvent(); pending=0; ResT=0; }`, one unconditional NextFloat), its two inputs are read PRE-CALL and reported in every record (`research_target`, `roll_pending_in`), and `region:rng` compared clean on all 35 of lane U's calls. BUT `roll_draws` was **0 on every one of them**: `ResearchRollPending` is normally consumed by `ServerPlayer::ProcessTurn` BEFORE ProcessResearch runs, because that call site fires once the progress ratio crosses its threshold - i.e. exactly the turns approaching completion. In lane U's Zuul run `roll_pending_in` is true for turns 8-12 and flips FALSE on turn 13, the turn before the tech completes on turn 14. So lane V's call-9 draw was the RARE case (a tech jumping from below the threshold to complete in one turn). Three sessions, three answers: 0 / 1 / 0. **The branch is inside the compare but has never been seen to fire** - needs a purpose-built save | | Zuul double roll (behavioural) | verify | verified | high | 100% | 2026-09-08 | CLOSED by lane V. No species-5 save existed so it MADE one: custom game, only Zuul in the Available Species pool, 4 End Turns. 8 calls, 8 compared, 0 divergent, exit 0; all four species=5 researching calls advance the generator by TWO (left 540->538, 522->520, 504->502, 485->483) and ours reproduced every post-state bit-for-bit. Was disassembly-only since 2026-09-08 morning. Save: verify/results/saves/zuul-turn5-species5.sav (and zuul-turn5.sav on the VM).

WORKAROUND: accept the default name and rename the .sav afterwards. Costs a save-naming step in every workload-building lane | | wire-schema channel (engine) | engine | verified | high | 95% | 2026-09-08 | Lane G REJECTED the brief's premise for good reason. objects/layouts.json is a MEMORY-layout projection and was the wrong input: serializers.py's 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. Lab.layout() already computed true disk order internally and it was being thrown away. New `tools/streams.py` is a SECOND projection keeping order and repeats and DROPPING EVERY MEMORY FACT (no off/size/sizeof/gaps/strides) - so the original's ABI never enters our runtime types, which was the design constraint. Offsets still have their home as `offset` entries in addresses.json for the shim, which legitimately needs them. gen_stream_schema.py -> include/generated/sots_stream_schema.h (386 classes, 2,042 items). SUBTLETY: the on-disk primitive is NOT layouts.json's `kind` - it comes from the stream vftable slot/helper, and a member held as int16/int8 is written by WriteInt and is FOUR BYTES ON THE WIRE | | schema as CHECK not codec | engine | verified | high | 100% | 2026-09-08 | Lane G's key judgement: the table is a SPECIFICATION, not a program. The recovery is a LINEAR pass over Write, so it cannot see branches (StarShip's BQ2 is gated on hbq but listed unconditionally) and it flattens container loops - a codec driven off it DESYNCHRONISES ON THE FIRST BRANCH. So hand-written io() shapes stay the codec and a new SchemaProbe archive walks them WITH EVERY BRANCH TAKEN (the same view the recovery has), LCS-aligned against the table: 56 shapes bound, 657 items matched, 0 mismatches | | NAMED coverage 38% -> 97% | engine | verified | high | 100% | 2026-09-08 | All four real saves round-tripped byte-identically BEFORE and AFTER - and lane G refused to call that a coverage claim, because `ar.any` bodies round-trip trivially by copying bytes nobody understands. New CoverageArchive separates items a FIELD NAMES from items a Node merely CARRIES: turn1/2/3 37.9/38.8/39.4% -> 97.1/97.2/97.2%; zuul-turn5 42.5% -> 97.6%. Ratchet at 95%. Newly typed: TechTree (both NumTechs sections), Events (3 nesting levels), ShipRecs, sprjs, civr, comms, spy2, spymgr, aid, Ojvs, AIEnf, FNG, trdmgr, Des section/gun-bank tree. STILL OPAQUE, honestly: CD custom data (744 items - TurnCommands_v5 is a NO-ORDERS snapshot, needs a save with issued orders), SvSctOb (147, eight EncObj variants), DOpts (94, read_elem lacks a std::string branch), spies2 (56, count 0 everywhere), RNG (2, correctly opaque) | | FOUR reader defects invisible to round-trip | verify | verified | high | 100% | 2026-09-08 | Present in BOTH readers, none catchable by a round-trip test. (1) SystemParams field 1 is a STRING, not an int - it is the empty string in every save, four zero bytes, byte-identical to int 0; it round-tripped BY LUCK and a named planet would have desynced both parsers. (2) ObservedTech/ObservedWeapon `odet` is a BOOL not an int (lane D's own golden table already said so); byte-safe only because a 4-char tag makes bool and int items both 12 bytes. (3) SpeciesRatios::nv and (4) ShipRecords::srbd are COUNTS, not fields. Lane G deliberately did NOT patch save_reader.py: every fix is byte-neutral on available saves, and quietly editing the oracle mid-campaign is worse than recording the divergence. THE ENGINE IS NOW THE CORRECTED REFERENCE; the Python oracle carries a logged open item | | RULE: interface stub -> look for the *Impl | objects | verified | high | 100% | 2026-09-08 | `trdmgr` RESOLVED, correcting the earlier "ServerTradeManager has no serializer" finding: the no-op Read/Write is real but THE CALL IS VIRTUAL - ServerTradeManagerImpl has the actual serializer. Same shape resolves IServerSpyManager -> ServerSpyManager. GENERAL RULE: when an interface's serializer is the inherited stub, look for the concrete *Impl. (Game::ShipDesign::Write genuinely still makes no stream call - but ShipDesignDef::Section IS recovered, so most of Des is typeable anyway) | | B3 hook: the completion path is now inside the compare | phase2 | verified | high | 95% | 2026-09-08 | NEW (lane U 2026-09-08). `Game::TechTree::ProcessResearch` in compare mode now reproduces not only what the function itself writes but the whole `SetResearched` completion path: the turn/order stamps, the child-cost sweep, the availability sweep, the newly-available collector that decides EVENT_TECHS_UNLOCKED, the de-duplicating ObservedTech append and the one RNG word RollResearchEvent draws. **35 compared calls across three workloads, 0 divergences, tracecmp exit 0 on all three.** FOUR pre-call reads make it work and each is a trap that reads back a PLAUSIBLE wrong answer if taken after the original: TechTree+0x20 (order counter, post-incremented -> every `order` off by one), ServerPlayer+0x294 (`ResT`, zeroed by the callback -> the extra RNG draw never modelled), +0x3b4 (pending roll, cleared in the same block), and the otch element names (already appended -> the dedup check 'agrees' with a count it never computed). All four are reported as ARGUMENTS so a run is auditable without trusting `ours`. COMPARE MODE ONLY: in replace mode applying half of OnTechResearched (the append and the roll, but not the ~90 tech-effect field writes) would leave the player in a state no code path produces | | CLEAN-RESULT DISCIPLINE: how a 0-divergence run was kept honest | meta | verified | high | 100% | 2026-09-08 | NEW (lane U). A clean result was EXPECTED here, which is exactly when a hook that silently models nothing slips through. Three things made that hard to hide and all three fired: (1) the 'did nothing' answer is KNOWN - it is `INT_MAX / 0 / -1`, precisely what lane V's report shows - so there is no null model that passes; (2) the collector ran on all 35 calls, not just the 4 completions, and had to come back EMPTY on the 31 quiet ones - an over-collecting transcription would have pushed `next_id` TOO HIGH and made those calls newly divergent; (3) the shim log prints per-call counters (`completions= unlocked= otch_appends= roll_draws= failures= depth= name_unreadable=`), so a clean compare with zeros on a completion call would have been visible as a clean compare of nothing. Reusable pattern for any lane whose expected outcome is 'no divergence' | | Prereq semantics come from the CODE, not the tech files | subsystem | verified | high | 100% | 2026-09-08 | NEW (lane U). `TechTree::PrereqsMet` 0x0057d8e0 (whole function): a prerequisite set is an **AND over groups, each group an OR over techs**, held as a flat entry array at `TechDef+0x88` (stride 8, `TechDef*` at +0) plus a vector of `{int start; int count}` groups at `TechDef+0x98/+0x9c` (stride 8). A tech satisfies its group only when its node exists IN THIS TREE and is state 4. TWO EDGE CASES THE DATA FILES DO NOT SUGGEST: **zero groups -> TRUE** (a tech with no `requires` is gated only by its parent edge), and **a group with zero entries -> FALSE, failing the whole test** (the inner loop cannot break, so the outer one exits with that group uncounted) - a 'vacuously true empty OR' reading gets this exactly backwards. Also `TechDef+0xb0`: a byte that excludes a node from the availability sweep entirely; named `TechDef_off_NoAutoAvailable` for what it DOES - the tech-file keyword `unlock_explicitly` matches the behaviour but ParseTech 0x0058b050 shows no reference to 0xb0, so the link is a HYPOTHESIS. `findings/subsystems/unlock-cascade.md` | | per-lane addresses.d fragment (second use) | meta | verified | high | 100% | 2026-09-08 | Lane U wrote `ghidra/addresses.d/lane-u.json` (12 entries; header 615 -> 627) rather than touching the shared `addresses.json`, and staged every sots-re change by explicit path.

Prediction COMMITTED BEFORE THE BUILD (engine 405ba41, docs/U-unlock.md 4, incl. 4.6 listing five ways the model could be falsified and the symptom of each). Outcome: 35 compared calls across THREE workloads, 0 divergences, tracecmp exit 0 on all three (first End Turn 3/0, five-turn 15/0, Zuul turn 5->15 20/0). End-Turn oracle checked FIRST (bb4fd9ac.../978041ac..., lane R's and lane V's hashes) - a clean compare from a build that moved the game would be worthless. ANTI-VACUITY EVIDENCE, which is the point: call 9 was NOT lane V's call (from turn 5 the AI picked a different target) - it completed tech 9 and unlocked three nodes at costs 13000/35000/4000 that appear in NO earlier report and were predicted by nobody, reproduced with zero divergences, so the model cannot have memorised numbers that did not occur. The collector also ran on all 35 calls and had to come back EMPTY on the 31 quiet ones (over-collecting would have pushed next_id TOO HIGH). Guards 9 undeclared in 2 calls vs 10 predicted - the miss is WORKLOAD not code (player+0x3b4 gone because the pending-roll byte was already 0; +0x196 replaced by +0x130 because a different tech completed) | | Zuul completion (double roll + cascade) | verify | verified | high | 100% | 2026-09-08 | Lane U took it: call 2, turn 7, species 5 - `left` 449->447 (DOUBLE ROLL) AND the cascade in the SAME call, next_id 10->12, observed_techs 396->440.

The draw is modelled, its inputs are read pre-call and reported in every record, and region:rng compares clean - but THE BRANCH HAS NEVER BEEN SEEN TO FIRE. The reason is a real finding: ResearchRollPending is normally consumed by ServerPlayer::ProcessTurn BEFORE ProcessResearch, because that site fires when the progress ratio crosses its threshold - exactly the turns approaching completion. In the Zuul run it is true for turns 8-12 and flips FALSE on turn 13, the turn before completion on turn 14. So lane V's call-9 draw was the RARE case and lane R's "15/15" the common one.

The eight ids in our saves had been identified by tag-sequence match; the table AGREED on all eight and added four more.

Confirms a save with issued orders is required (lane O). ALSO SPLIT INTO TWO PROBLEMS: TurnCommands_v5 (blocked on a workload) vs THREE AIAgent blocks (~236 items each = the BULK of the 744) which are Game::StrategyAIAgent::Streamable with NAMED tags, statically tractable, ~10 nested shapes - deliberately left for a following lane since it is AI cache state, not orders | | SvSctOb side findings | objects | verified | high | 100% | 2026-09-08 | `indsys` = Game::SVSOIndependentSystems, whose Read AND Write are both the shared `ret 4` stub - its EMPTY FRAME IS CORRECT OUTPUT, not truncation.

NUANCE: defects 3 and 4 were an ABSENCE in save_reader.py, not an error - ShipRecs and civr were both A(...,"any"), so the fix ADDED typed shapes rather than retyping a field, a bigger change than my brief implied. srbd turned out BEHAVIOURALLY CONFIRMED not inferred: it takes 0/1/3/4 across players and every non-zero count is followed by exactly srbd x 5 scalars (turn3 player 4: srbd==4, 20 items) - read as a field those trailing scalars have no explanation. `nv` is WEAKER: only ever 0 or 1 in these saves, so the multi-pair case is synthetic | | save_reader silent-agreement failure mode | verify | verified | high | 100% | 2026-09-08 | Forced into the open by lane W's tests: save_reader.py's walker types "." items from its OWN kind catalog, not the schema passed in - so on the real saves the catalog and the old schema agreed with each other AND WERE BOTH WRONG.
