fix(crash): EndPlay tore the world down under live workers -- the cache made it lethal
PIE crashed with EXCEPTION_ACCESS_VIOLATION reading 0xffffffffffffffff:
FRoomGraphSource::Eval() VoxelDensityOpStack.cpp:3056 (Manager->GetLayoutVersion())
UVoxelGenerator::GetDensityAt() VoxelGenerator.cpp:1103 (ActiveOpStack->EvalMC)
... AVoxelWorld::LoadTile lambda, on a task-graph worker
Two lifetime bugs, combined:
1. EndPlay gave up after a 3-second deadline and destroyed UObjects while workers
were still inside GenerateTileResult. The crash log records 4, 3 and 7 tasks
still running during teardown. ARCHITECTURE has always said EndPlay blocks on
ActiveTaskCount -> 0; it did not.
2. e08b49a's worker-local cache keeps 128 built op stacks alive per thread, and
those stacks hold a raw UVoxelStrateManager*. Before the cache, a stack was
rebuilt at every chunk crossing and never outlived its owner for long. After
it, a freed manager stayed reachable and got dereferenced.
The cache did not create the teardown race. It made an existing one lethal.
Fixes:
- EndPlay now waits unconditionally for ActiveTaskCount == 0. The 3s deadline is
demoted to a log line: a slow drain is reported, teardown is never torn out
from under a reader.
- UVoxelStrateManager carries a process-unique CacheLifetimeId, folded into the
cache key. Deliberately not a UObject pointer: allocator address reuse must not
let a stale worker-local stack look current across PIE sessions. PassagesVersion
restarts per layout and cannot make that distinction.
- Cached passage/room manager references are weak pointers, fail-closed.
- Verified FStrateGenerationParams is copied BY VALUE into tunnel operators, and
stack moves preserve owned operator allocations, so no operator references a
previous cache entry's parameters.
TunnelNetwork mesh 342.332 s -> 16.199 s (21.1x)
per tile, 64 tiles 5.349 s -> 0.253 s
NOT verified, and it matters here:
- No PIE measurement. The owner restricted this session to analysis and fixes, so
the numbers above are the commandlet's direct-mesher path, NOT the streaming
path the game uses. They are not game timings and are not presented as such.
- The 128-slot cache may churn at distance: an L0 tile crosses at most 27 exact
chunks, but L2/L3/L4 tiles touch 216 / 1,000 / 6,859 chunk keys. Whether that
helps or hurts in game is unmeasured.
- EndPlay waiting forever converts a crash into a hang if a task never observes
bShuttingDown. Workers do check it, but this trade is deliberate and worth
watching.
Named, not changed: the straight "roads" the owner still sees are inter-strate
passages. FStratePassageConfig defaults Connections=1 and Style=Straight
(VoxelStrateTypes.h:1781); GeneratePassages maps Straight -> SlopedTunnel and
builds a two-leg switchback that FPassageCarveOp carves
(VoxelStrateManager.cpp:819).

perf(gen): a thrashing one-slot cache cost 18.7x -- and the world is unchanged
TunnelNetwork density evaluation was 45x more expensive than Maze for identical work: 2,097,152 voxels, 64 tiles, same mesher, same machine. Profiling killed every hypothesis I brought to it -- box classification skipping 0/64 tiles was true but irrelevant (export bypasses classification), near-surface early-outs fired at 49.7%, the room cache built 340 entries for 2.74M samples, and the per-room overrides resolved once per sample rather than once per modifier. The cause was the wrapper, not the stack. A mesher tile samples an EXPANDED grid (-1..Cells+1), so one worker crosses several exact chunk coordinates while meshing a single tile. The generator's cache held only the last coordinate, so every boundary crossing rebuilt the resolved parameters, the whole 22-operator stack and the tunnel-core cache. On one representative tile: 3,675 refetches, 38.0s. The entire operator stack was 18.5s of a 4,272s total -- 0.43%. Replaced with a 128-slot direct-mapped thread_local cache keyed on owner, chunk, layout version, params fingerprint and generator type. Collisions force a safe rebuild, never a stale read. No shared mutable state, no order-dependent reduction. TunnelNetwork 344.5s / 164.267 us/vox -> 18.4s / 8.763 us/vox (18.7x) Maze 7.4s / 3.535 us/vox -> 1.08s / 0.513 us/vox ( 6.9x) same tile 38.0s -> 0.51s ; refetches 3675 -> 27 Output is BYTE-IDENTICAL, before vs after and across repeats, both archetypes: TunnelNetwork 50d6b4d0..f23126, Maze 364f7489..2fbe99. The permission to change the field was not needed. Also in this commit, from the two preceding tasks: - Explorer renders from the MESH instead of raymarching. It meshes the region once through the canonical UVoxelMarchingCubesMesher, then CPU-rasterises via a BVH. A viewpoint went from ~16 minutes to 0.155s; 8 views now cost 1.25s of drawing. No render pixel samples the density field. - One sampled grid and player-fit mask per run, shared by render/walk/export, instead of the same 368s walk computed twice. - A wall-clock budget (25 min default, hard 30 max) that stops cleanly and records truncated/truncated_during/completed_modes rather than overshooting. - ParallelFor across the measurement sampling; the suite was ~10% of a 16-thread machine. - -surfaceroughness= on the commandlet, and a surface-relief metric in export mode (edge lengths, dihedral distribution, face-vs-smooth normal divergence) so "does this look like rock" is a number, not a screenshot argument. - Smooth vertex normals in the rasteriser: FVoxelMeshData::Normals is the density-gradient normal the engine shades with, and the raster path was recomputing a face normal over it. - ScaleDiagnosis: baked candidate indices are now derived from the current corpus, so a legitimate field change stops breaking the test. NOT verified, and not claimed: - TunnelNetworkSpineEquivalence exceeded the 30-minute cap and was stopped. Inconclusive, not passing. The identical hashes are strong evidence the op-stack/legacy equivalence holds, but the test has not confirmed it. - CrossPlatformDigest passes but reports 2 samples within 1e-6 of the isosurface; FMath::Sin/Cos leaves Windows/Linux equivalence unproven. Pre-existing, not caused by this change. - The cache's memory footprint (128 entries x ~16 workers) is unmeasured. What the roughness sweep settled, for the record: SurfaceRoughness 0 -> 8 moves cost by 0.3% (163.2 / 163.2 / 163.7 us), so roughness was never the cost. It does reach the surface (dihedral p50 1.1 -> 2.2 -> 5.9), which kills my claim that the density-channel operator contributed nothing. TunnelNetwork's hard seams are present at roughness 0 (4.4% of edges past 40 deg vs Maze's 1.0%), so they are structural -- in how primitives are unioned -- not a roughness deficiency. More roughness makes them worse, not better. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012aheo2crrZmHuYtPpdY2Cb |

feat(gen): Jahni's playtest corrections -- rooms flattened, roads deleted
From walking a TunnelNetwork preset at (0,0). Four corrections, and two of
them were the same mistake.
2a. The (0,0) landing room is sized to host a FUTURE straight vertical
shaft from the surface, with flooring around the origin itself. The
room is the landing for a shaft the player digs later.
2b. The inter-strate descent no longer starts at the spine -- placed by
deterministic hash within a radius around (0,0). The spine room is for
the surface shaft; the descent is elsewhere.
2c. ⛔ DELETED the landing->hub connector roads from

feat(descent): landing ROOMS and a walkable tunnel -- per Jahni's correction
Jahni corrected the design: "the connection between level is a tiny tunnel
connecting both strate, not vertical, it needs to be walkable" and "'the
spine' shouldn't be carved except optionally from the top first strate,
then it's used to have a landing room".
COMPOSER-NOTES §6.8 had said the spine "provides a clean landing space, not
a continuous open shaft" -- and the implementation carved a vertical
cylinder anyway. A vertical cylinder has no walkable floor except at its
bottom, so a carve guaranteeing open AIR guaranteed nothing STANDABLE.
That one omission is behind five of my dead hypotheses this week.
Now:
origin spine a finite rounded ROOM per strate, no vertical bore.
radius 14 -> 8 m wide, 7.5 m tall
descent a walkable tunnel, single-file by design: 3 m mouth,
2.5 m waist, gradient capped at a NAMED 15 deg
exotic styles VerticalShaft / SpiralDescent / CascadingDrops /
CrackCrevice preserved, no longer the default
⚠️ THE GEOMETRY BITES, and it is worth Jahni's eye: at 15 deg a 32 m drop
needs 119.4 m of horizontal run -- about 59.7 m per switchback leg. That is
a long walk between strates. It is the honest consequence of "walkable",
not a tuning artifact, and the alternative is a steeper number.
⭐ AND THE ROOT CAUSE GOT NAMED A THIRD TIME, by Codex mid-run: "the round
tube was hollow air but had no authored support strip, so 'open' still did
not mean 'standable'." Tunnels now carry a floor band, and the root join
terminates in the finite origin room rather than an annular shaft hub.
Measured, commandlet sweep, 8 archetypes x 8 seeds, 64/64 valid:
origin column has player-fit cells 17/64 -> 63/64
origin column reachable 0/64 -> 7/64
arrival landing probes 315/320 fit AND in the arrival component
tunnel audit 5,916/5,916 floor and capsule samples pass; zero gradient,
floor, capsule, geometry or seal failures
narrow-gap events 0 box verdicts 14 checked, 0 violations
⚠️ arrival->departure is 6/64. The landings and tunnels are now provably
walkable; what remains is the INTRA-STRATE vertical connectivity problem

test(explore): 81 runs in an afternoon -- every failure is a DROP, not a squeeze
First real use of the commandlet, and it paid for itself immediately: 64
sweep runs + failure renders + origin probes, which at the old 73-minutes-
per-automation-run would have been days.
⭐ FINDING 1: THE WORLD IS FRAGMENTED VERTICALLY, NOT PINCHED.
Across all 64 runs: ZERO narrow-gap events. Every failed run has separate
arrival/departure fit components with a positive gap, 12.75 m to 72.98 m.
So corridors are not too tight anywhere -- the space is severed.
And for the first time in this project we LOOKED at a failure instead of
inferring from aggregates:
FlatPlain/42 "a broad flat floor sheet with a sharp diagonal ledge
descending into black open space" -- a drop, gap 63.9 m
SurfaceWorld/7 "terrain shelves and a large black void between them.
There is no connecting floor" -- gap 51.8 m
Maze/42 "a massive solid rock wall/overhang fills the separation"
-- gap 27.7 m
I checked the images myself. FlatPlain shows two floor LEVELS 27 m apart
in Z with nothing joining them.
⇒ The missing thing is VERTICAL CONNECTION between floor levels. Ramps,
slopes, ledges, stairs. Every archetype builds floors; nothing builds a way
between them.
⭐ FINDING 2: THE ORIGIN HUB IS NOT REACHABLE, which contradicts

feat(explore): a commandlet -- 91x faster, and the first real PICTURE
Every experiment in this project cost a build + full-suite cycle. The
landing task took 52 of them over ~9 hours. And nobody could SEE the world:
every visual judgement all session was made on density SLICES -- diagrams,
not pictures. That is how a floor heaving 1.4 m every two metres got
described as "roughness visible but modest" while Jahni spotted it in
thirty seconds by walking it.
-run=VoxelForgeExplore, editor-only module, three modes, one build many runs:
render raymarched PNGs, fixed 0.25-voxel step + 10 bisection iterations
(NOT sphere tracing -- the op stack yields density, not a signed
distance, so a long step tunnels through walls). Three views, each
with a 1.76 m human marker in frame, because every scale mistake
here came from numbers with no body beside them.
walk an agent using the EXISTING VF player-fit stencil, never its own
movement model -- two definitions of "can a player stand here"
would drift and we could not tell which was lying.
export OBJ through the canonical UVoxelMarchingCubesMesher. No second
mesher; a forked meshing invariant is the bug this project keeps
paying for. 23.2 MB, 106,762 verts, 200,842 tris for 128^3.
⭐ THE NUMBER THAT JUSTIFIES IT: the full automation run takes 4,396 s
(73m16s). The commandlet does all three modes in 48.1 s wall, 5.9 s of
which is engine startup. ~91x faster. And I had guessed the suite cost
~90 s -- it is 73 MINUTES. The iteration loop was far more expensive than
I knew.
First real walk metrics on the Maze (seed 0, slot 4):
distance 214 m · tortuosity 4.98 · dead ends 0.935/100 m
narrow-gap events 0 · reachable fit fraction 3.01%
result NotConnectedAtThisResolution
Tortuosity ~5 is a genuinely winding route, which is right for a maze.
3% reachable is not.
Editor Development build clean. SHIPPING build clean with the receipt
containing VoxelForge and NOT VoxelForgeEditor -- the instrument cannot
reach a packaged game. Automation 32/32, 0 failed.
⚠️ Codex initially shipped this UNBUILT, and correctly: I omitted the
## Validation section from that spec, so it fell back to CLAUDE.md's
"NEVER build or compile". 100+ compile errors from three causes -- bare
TCondensedJsonPrintPolicy and TJsonWriter needing their template
arguments, and a missing UObject/Package.h. That include is the SECOND
miss this session, so CODEMAP §6 now carries the gotcha.
⚠️ Unrelated, found in passing: VoxelForge.uplugin does not declare
RealtimeMeshComponent although the runtime module uses it.

feat(passages): §6.5 landings -- you arrive somewhere you can stand
The last unbuilt Tier 1 item. A passage was a bore through rock with no floor inside the walkable angle, so its mouth was not a standing position and neither was anything near it -- the departure mouth measured a FOUR-CELL player-fit component. You arrived and there was nowhere to stand. Both ends of all 7 passages now open into a landing, sized from the body: capsule diameter 2.72 vox floor >= 12 vox (3 m) to stand and turn capsule height 7.04 vox room >= 12 vox tall, stock mouth gives 18 (4.5 m) 3-voxel floor slab, tube tangent to it -- no lip to climb out of connector 5-vox radius: 2.5 m clear width, 3 m clear height ramps over 44 deg get a deterministic level dog-leg ⭐ THE MOUTHS ARE NO LONGER SPECKS: archetype components largest arrival-departure Maze 309 -> 340 176 -> 3210 43-81 -> 3210-3210 TunnelNetwork 467 -> 227 1292 -> 3841 2-1 -> 3841-269 Underwater 86 -> 117 35 -> 3838 3-11 -> 3838-267 FlatPlain 45 -> 11 259 -> 2130 1-1 -> 268-273 CrystalChamber 197 -> 90 24 -> 286 1-1 -> 286-274 FloatingIslands 2 -> 1 3 -> 72 1-1 -> 72-72 Law 1/8 -> 2/7 connected (1 refused on MaxCells), and critically ZERO connections now run through a four-cell pocket. Every landing floor was verified against the FINAL density, after all posts: 14/14 pass the 44 deg slope bracket, worst room gradient .059, worst connector .522. 14/14 deterministic root joins. 0 seal failures. 0 box-verdict violations across 82 proved + 174 mixed, 109,142 voxels. Op-stack bit-identical, order-independence green over 10 slots / 31 passages / 3 pool orders. Cache 0.665 us rebuild, 0.646 us hot. Post order: origin spine -> vertical seal -> passage tube + landing floor -> XY edge seal. Landings clamp 4 voxels inside the vertical seal; the XY seal stays last and wins at world edges. ⚠️ ARCHITECTURAL NOTE, not a detail: landings join a deterministic annular ROOT HUB at (0,0), built identically for every endpoint -- no nearest- component search, no passage ordering. That is what makes the join guaranteed rather than likely, and it extends the (0,0) spine concept from a landmark into a structural network. It also means routes tend to pass through the centre, which is a gameplay consequence worth Jahni's eye. ⚠️ AND IT DOES NOT CLOSE THE LAW. Codex is explicit: the landings guarantee membership in the new root network, NOT in the archetype's pre-existing fit component. The whole-strate Maze check still shows a 71.9-voxel gap between 1,235 and 2,938-cell components. So the native corridor networks remain disconnected from the root network in places. Real, separate, next. 52 build-and-measure cycles, ~9 hours, finding real geometry bugs on the way (a landing floor overlapping the ramp cells and hiding a floor discontinuity; the disturbance pass refilling connector headroom). Build clean, 32/32 success, 0 failed. Showcase regenerated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K8V9my1PL68pmQb2gutZZV |

test(measure): the window was NOT the problem -- my sixth hypothesis dies
I thought the fitted mouth-AABB window was cropping an origin-routed path and producing a false NotConnected. Codex tested it three ways at step 1 on the Maze candidate Jahni walked: mouth-AABB + margin 842,996 cells NotConnected origin-inclusive 3,251,556 cells NotConnected WHOLE STRATE 31,881,528 cells NotConnected 115,578 fit cells, 2,903 components, largest 11,418 -- and the mouths sit in components of 172 and FOUR cells, 274 voxels apart. The window was never the problem. Sixth measurement hypothesis, first one that was wrong in the other direction: this time the instrument was fine and I doubted it. The window rule still improved: bIncludeOriginInCoverWindow now covers the route an origin-rooted topology actually implies (Maze, VerticalShafts, TunnelNetwork, Underwater), expansion happens BEFORE MaxCells, and an over-cap window is REFUSED honestly instead of silently cropping back to a mouth-only box. VerticalShafts refused at the 4M production cap and said so. Corrected law across eight: 0/7 measured Connected, 1 unknown (CoarseLiedBudgetExhausted), 1 refused. ⇒ FIVE CAUSES NOW ELIMINATED: size (Jahni walked it), the fit stencil (fixed, 309 pockets -> 96), placement (mouths land on legal poses), corridor connectivity (spanning tree, 0 disconnected cells over 64 seeds), and the measurement window (whole-strate says the same thing). ⭐ AND THE REMAINING CAUSE IS NAMED BY ITS OWN NUMBER: the departure mouth sits in a FOUR-CELL player-fit component. A passage tube is a bore through rock -- sloped or vertical, no floor within the walkable angle -- so the mouth point is not a standing position and nothing around it is either. You arrive and there is nowhere to stand. That is precisely COMPOSER-NOTES §6.5 / Tier 1's unbuilt item: "the passage mouth becomes a room plus a distinctive landmark". It was never started. The law cannot pass while a mouth opens into a bore instead of a landing. Build clean, 32/32 successful, 0 failed, same two known warnings. WorldRadiusVoxels=0, lateral gating, determinism, equivalence all intact.

feat(maze): a spanning tree -- it is a maze now, not a grid
Jahni: "mostly a cube full of straight pathway along the edges... basically
just a repeating pattern of tunnel connecting to each other, definitely
unwanted". And the measurement: the arrival mouth in a 30-cell pocket while
the network held 1,217. SAME CAUSE -- edge selection was independent hash
gating per +X/+Y/+Z edge, i.e. a random subgraph of the cubic lattice.
Every junction identical, and connectivity left to chance.

fix(passages): land mouths where a BODY fits -- and the cause is now cornered
VF_SuggestLandingPoint aimed at open AIR. Air is not where a body fits: a mouth could sit in a perfectly open pocket no capsule can stand in. It now requires a legal capsule pose -- clearance (r 1.36, half-height 3.52), support within a 1.8-voxel / 45 cm step height, a walkable support PATCH (4 of 5 columns, centre required, slope <= 44.8 deg), positive density throughout the capsule, strict 2x seal interior, bounded lateral snap. It stays a PURE free function, which was the hard constraint -- GeneratePassages runs inside Initialize while the layout is half-built. So it cannot flood-fill, and Codex correctly did not pretend otherwise: it aims at deterministic guaranteed features instead (room centre/floor, slab floor, horizontal maze edge, shaft feature-core ledge pose, island top). Both mouths query their own strate independently; no passage chaining, so LayoutOrderIndependence stays green. Placement measurably improved: Maze comps 309 -> 82, largest 176 -> 1217, gap 206 -> 122 VerticalShafts comps 112 -> 36, largest 96 -> 619 CrystalChamber gap 47.5 -> 19.1, departure mouth now in a 717-cell comp Underwater comps 86 -> 13 ⚠️ AND THE LAW IS STILL 1/8. Reported honestly rather than tuned. Mouths now land on legal body-sized poses; the poses just are not connected to each other. ⇒ BY ELIMINATION, THE CAUSE IS GENERATION. Four candidates, three dead: size DEAD -- Jahni walked it; bore measures 3.62 m vs 3.677 m spec the stencil FIXED -- fragmentation was 3x overstated by an exact-Z-1 floor placement FIXED -- mouths now sit on legal poses, several in large comps GENERATION STANDS -- body-sized space exists in big components that do not reach each other ⭐ AND THE MAZE TIES TWO OF JAHNI'S COMPLAINTS TOGETHER. Its arrival mouth lands in a 30-cell pocket while the main network holds 1217. Edge selection is INDEPENDENT HASH GATING per +X/+Y/+Z edge (VoxelDensityOpStack.cpp:582/584/586) -- so the corridor graph is a random subgraph with no connectivity guarantee, exactly the percolation failure VerticalShafts had before its drainage tree. That is the same root cause as "mostly a cube full of straight pathway along the edges": a spanning tree would make it BOTH feel like a maze (dead ends, uneven runs) AND be connected by construction. One fix, two complaints. Codex found a real error in my spec: an infinite shaft cylinder has no support surface AT its axis, so the old exact-axis assertion was unsatisfiable. It now requires a deterministic feature core and audits tree connectivity from the resolved axis. Build clean, 29 succeeded / 0 failed / 2 known deliberate warnings. Box audits 0 violations. Shaft refinement 16/16. Order-independence green across 10 slots, 31 passages, 3 pool orders.

fix(measure): the fragmentation was the instrument -- 309 pockets -> 96
Jahni walked the maze end to end while the metric called it 309 disconnected pockets whose largest held 176 cells, with the arrival mouth in a THREE-CELL pocket. Direct observation beat the instrument, again. Cause, found exactly: the stencil demanded a solid cell at precisely (X,Y,Z-1). No supporting-surface search, no slope tolerance, no step height. At step 1 a floor that slopes even slightly loses its solid cell under most of its air, so a walkable corridor dissolved into specks. Now: a bounded downward search for a COHERENT SUPPORTING SURFACE within a step-height tolerance (MaxStepHeight 45 cm = 1.8 voxels), a walkable-slope normal test (WalkableFloorAngle 44 deg), then the full capsule re-tested at the resolved support height. Deliberately NOT "any solid within N cells", which would accept ledges and isolated pixels. ⭐ ON THE WALKED MAZE (seed 0, index 50, slot 4): components 309 -> 96 largest 176 -> 1401 fit cells 2801 -> 6668 mouth comps 43/81 -> 147/1401 The 300-pocket world was a measurement artifact. Fifth time this session the instrument was the suspect; fourth time it was the culprit. ⚠️ AND IT IS NOT SELF-FLATTERING -- a metric change that only ever makes numbers rise is worthless, so it ships with controls that must REJECT: vertical shaft wall 0 fit cells isolated 1-voxel ledge 0 fit cells overhang underside 0 fit cells ramp steeper than 44 deg 0 fit cells coarse step 4 refused, not guessed Open flat-floor control: 6.13% of air cells fit, ONE component of 12,168 -- sensible, since only near-floor poses qualify in a tall room. ⚠️ BUT THE ROUTE STILL DOES NOT EXIST, and that part of H3 survives. The law is 1/8 before and after -- what changed is its honesty: the one connection used to be FloatingIslands through FOUR cells, and is now FlatPlain through 2,221 with a zero gap. Seven archetypes still have both mouths in separate player-fit components 56-169 voxels (14-42 m) apart, and those components are now large and real (663-2902 cells), not specks. ⇒ So the world HAS substantial connected player-sized space. The passage MOUTHS are not landing in it. That is the Tier 1 landing problem again, one level down: VF_SuggestLandingPoint aims at open AIR, and air is not where a body fits. Next task. Codex found three errors in my baseline quoting, all mine: I wrote "0/8 connected" while also saying one connects through four cells (it was 1/8), misquoted SurfaceWorld's gap as 1101 when the saved value is 110.648, and mixed provenance on the VerticalShafts row. Build clean, 31 succeeded / 0 failed. The 2 warnings are both deliberate: the lateral-regions gate, and a test reporting that its own sample "barely asked its question".

test(diag): H1 dead, H3 measured -- player-sized space is SHATTERED
Diagnosis only, no generation or parameter changes. ⭐ H1 IS DEAD, confirmed by Jahni's playtest and by measurement. He walked the maze candidate: "i CAN go through it, the tunnels are just the right size with very tiny wiggle room." The radial probe agrees: measured bore span 3.62 m against a 3.677 m parameter. The carve produces what it claims; the scale change worked. ⭐ H3 IS WHAT THE NUMBERS SHOW. Player-sized volume EXISTS but is broken into hundreds of disconnected pockets, with the two mouths in different ones, tens to hundreds of metres apart (step 1, fitted window): archetype fit cells components largest arrival/departure gap Maze 2801 309 176 43 / 81 206 vox (51 m) TunnelNetwork 2748 467 1292 2 / 1 164 vox (41 m) VerticalShafts 1156 112 96 3 / 36 94 vox (24 m) SurfaceWorld 713 520 6 1 / 1 1101 vox (275 m) CrystalChamber 655 197 24 1 / 1 48 vox Only FloatingIslands connects, through FOUR cells. ⚠️ BUT I DO NOT ACCEPT "H3, therefore the world is shattered" YET, and the reason is Jahni. He WALKED a maze end to end that this metric says is 309 disconnected pockets whose largest holds 176 cells. Direct observation contradicts the instrument. An arrival mouth sitting in a THREE-CELL pocket is not a description of a cave; it is the signature of a stencil that fragments a continuous floor. H2 is the likely cause of that fragmentation, and Codex found it exactly: the fit test demands a solid cell at EXACTLY (X,Y,Z-1) -- no supporting- surface search, no slope tolerance, no step height. HeadroomCells applies only to the legacy walkable metric, not the capsule mask. VoxelStrateMeasure.cpp:697 (stencil), :729 (the exact-floor test) At step 1, any floor that slopes or is rough loses its solid cell at Z-1 under most of its air, so a walkable corridor dissolves into specks. ⇒ SEQUENCING: fix the stencil first, THEN re-measure H3. Until the instrument stops shredding continuous floors its component counts cannot be trusted. Fifth time this session that the measurement was the suspect. Recommended stencil, Codex's design and I agree: a bounded downward search for a COHERENT SUPPORTING SURFACE within a step-height tolerance, then re-test capsule clearance at that support height -- explicitly NOT "any solid within N cells", which would accept ledges and isolated support pixels. Fixed the mixed-resolution reporting that nearly cost me a false finding: fields are now coarse_step4_* and *_step1, never both unlabelled on one line. Recorded from the playtest, not acted on: - The maze is a GRID, not a maze. Edge selection is independent hash gating per +X/+Y/+Z edge (VoxelDensityOpStack.cpp:582/584/586), so every junction looks alike. A spanning subset would give dead ends and uneven runs. - TunnelNetwork DOES have explicit room-to-room connections (VoxelCaveMorphology.cpp:1406 backbone, :1465 tunnels) -- so Jahni's "lack of real passageway" applies to FlatPlain/CrystalChamber, which are slab voids with no room graph at all. - Two-abreast wants 2.5-3.0 m usable floor; a 4 m circular bore gives ~2 m. Build clean, 31 succeeded / 0 failed, run by me after Jahni closed the editor (the previous attempt could not link -- the DLL was held by his running editor).

feat(scale): size the world to a human body -- and it is NOT enough
Jahni: "can't you try and make the world to scale?" Every length parameter is now derived from the body and annotated with its metre value, so nobody has to do the arithmetic to notice something is absurd. CorridorRadius 4 -> 8 1 m -> 2 m radius (4 m bore) CellSize 40 -> 64 keeps a real wall between wider corridors TunnelMinRadius 3 -> 6 0.75 m -> 1.5 m ShaftMinRadius 5 -> 8 1.25 m -> 2 m IslandMinRadius 18 -> 24 4.5 m -> 6 m MouthRadius 6 -> 8 passage mouths 4 m plus passage reach, spiral, cascade, bridges, ridges, chasms The reasoning that motivated it still looks right: a 2 m circular bore for a 1.76 m player clears the head only along the exact centreline, so almost no cell has a floor with 7.04 voxels of clear air above it. A 4 m bore is genuinely walkable. ⚠️ BUT IT DID NOT FIX TRAVERSABILITY, and this time it is not the instrument. The player-fit law is measured at STEP 1 on a mouth-fitted window -- full resolution, both mouths inside the box -- and across the eight showcase archetypes it reports: 6 NotConnectedAtThisResolution (real negatives at full resolution) 2 OutOfWindow (unmeasurable, not passing) 1 StartCellNotPlayerFit (the arrival mouth itself is too small) 0 CONNECTED And every archetype reports hard-gate survivors=0, so the showcase is displaying the least-bad of an entirely failing set. ⛔ DO NOT READ player_fit_fraction / player_clearance FROM THE SHOWCASE LINE. Those come from the COARSE step-4 measurement in the same log line, where the 1.36-voxel player is sub-cell and fit is unmeasurable -- player_clearance reads a uniform "1.00 voxels" for all eight archetypes, which is one cell, not one voxel. Only restricted_law is at step 1 and only it is trustworthy. Fixing that mixed-resolution reporting is next. So scale was necessary and insufficient. My hypothesis was that bore diameter versus body height was the binding constraint; doubling it moved nothing measurable. Something else is preventing player-sized volume from existing at all -- worth finding before tuning any further. Codex applied these edits and then died mid-poll without validating them (third time a killed agent left a clean-looking unbuilt diff). Build and suite run by me: build clean, 30 succeeded / 0 failed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K8V9my1PL68pmQb2gutZZV |

feat(measure): a player does not fit. The law was passing impossible routes.
Jahni walked composed strates for the first time: "'maze' is way too tight tunnel radius wise, i can't enter nor anything". The candidates he could not enter were the ones our metrics ranked BEST -- Maze had the highest walkable fraction (.285) and highest connected surface (.99) of all eight. ⭐ THE HEADLINE, AND IT IS BAD NEWS WORTH HAVING: old arrival->departure law passing on 7 of 8 candidates player-fit-restricted law CONNECTED ON 0 OF 8 **The primordial law has been passing on routes no player fits through.** Every "the world is traversable" claim in this project measured air, not passage. Player-fit fraction across the eight showcase candidates ranges .0000 (FloatingIslands -- literally zero) to .0117. The season composer now returns 0 survivors for 6 required slots, and the showcase gate rejects 8 of 8. That is the correct outcome. The gate is not tuned to a threshold; it requires a resolved player-fit volume and a connected player-fit route. Capsule confirmed by Jahni as the base ACharacter: 34 cm radius, 88 cm half-height = 1.36 voxels radius, 7.04 tall. Named constant with the derivation beside it. Two traps avoided, both of which would have produced confident nonsense: - THE COARSE GRID CANNOT RESOLVE A PLAYER. SampleStep 4 makes a cell 4 voxels, ~3x the player's radius, so fit is below the resolution of every metric built so far -- which is exactly why nothing flagged an impassable maze. Fit runs on step 1 and REFUSES (bPlayerFitResolved=false + reason) when the step is too coarse. - Manhattan distance >= Euclidean, so reusing the existing transform for clearance would OVERESTIMATE free space and report fits that do not exist. Clearance uses a separate Chebyshev transform; Manhattan stays only on the legacy feature-scale metric. ⚠️ MY ROUGHNESS HYPOTHESIS WAS WRONG, and Codex disproved it rather than confirming it. Forcing SurfaceRoughness=0 on the Maze moved PlayerFit .0105 -> .0138 and the restricted law stayed NotConnected. Minimum corridor clearance is 1.00 voxel (25 cm) with or without roughness -- the corridors are simply too tight for a 34 cm capsule, full stop. Roughness IS still a real pinch risk where reach exceeds corridor radius: Underwater 2.21x, FlatPlain 2.31x, CrystalChamber 1.81x, TunnelNetwork 1.44x on corridors, VerticalShafts 1.30x on connectors. The 5.625-voxel default bound stays dangerous. Islands measured, not changed (feel is Jahni's call): 0/2 touch either seal, median clear gap 47.8 above / 9.0 below -- but effective radius spans 27-258 voxels at H=128 with ThicknessRatio .546, so the worst case has zero guaranteed separation. Recommendation recorded: radius back to 18-42, StrateHeightInChunks 4 -> 6, ThicknessRatio <= .40. Build clean, 30 succeeded / 0 failed, verified in the namespace log.

feat(runtime): the composed world can BE the game world
Jahni: "can you not implement those settings? as in, have them be live in
game?" This is that. The composer stops being a lab tool.
THE ARCHITECTURAL LINE, which is the whole design (COMPOSER-NOTES §3.1):
COMPOSITION stays editor-only, EVALUATION becomes runtime. Rolling,
measuring, preview, selection, promotion, the corpus -- none of it reaches
a player's machine. What crosses into the runtime is exactly two things:
reading a season manifest, and materialising a recipe into an op stack.
UVoxelSeasonAsset a cookable UPrimaryDataAsset holding the manifest,
so a season ships in a packaged game. The JSON
stays the reviewable, git-diffable artefact.
UVoxelSettings::Season optional. Unset => behaviour is exactly as today.
GetEffective*() season seed / spine radius / world radius / season
number override the authored values when assigned.
The test deliberately sets DIFFERENT authored
values, so "the season is authoritative" is proved
rather than coincidental.
⭐ MULTIPLAYER DETERMINISM, PROVED: two independent runtime managers built
the same season and compared 393,216 density samples BIT-IDENTICALLY. This
is the property the whole multiplayer model rests on -- replicate seed +
layout + diff, never geometry.
⭐ AND A STALE SEASON IS DETECTABLE, NOT SILENT. Initialize() now returns
bool and an assigned-but-invalid season NEVER falls back to the authored
pool. Falling back would hand a client a world that looks fine and is not
the season -- silent divergence, the worst failure mode in a shared world.
GetCurrentSeasonContentHash() is exposed BlueprintPure to compare at join.
HasComposerRecipeOverride() is gone. It force-classified every custom recipe
as Mixed, which was correct while box verdicts were only proved for
hand-written stacks -- but

feat(composer): showcase of all 8 archetypes -- and "not navigable" answered
Jahni asked for one strate per archetype to look at, and said the previews looked "not navigable nor anything except maybe the mazes". Both delivered. ⭐ PART A -- HIS EYE WAS RIGHT, AND SO WAS THE METRIC. BOTH EXPLANATIONS WERE TRUE, and they split by archetype: archetype walkable FLOOR AREA largest connected surface CrystalChamber .059 .9999 1.00 FlatPlain .048 .9985 .9998 SurfaceWorld .064 .9374 .9936 Maze .285 .2629 .9905 Underwater .229 .2061 .3312 TunnelNetwork .155 .2084 .4640 VerticalShafts .108 .1138 .1449 FloatingIslands .004 .1016 .4992 1. THE METRIC WAS WRONG FOR CHAMBERS. Walkable fraction is volumetric: an air cell with solid one step below and headroom above. In a cathedral almost no air cell is near a floor, so a huge open room scores ~.06 while a tight maze scores ~.29. It was measuring CORRIDOR-NESS, not navigability -- and mazes win that by construction, which is exactly the pattern he spotted. Slab families actually have 94-100% walkable FLOOR AREA, fully connected. They were never the problem. 2. AND FOUR ARCHETYPES ARE GENUINELY FRAGMENTED, which is a real content finding, not an artifact. Largest connected walkable surface: VerticalShafts .14, Underwater .33, TunnelNetwork .46, FloatingIslands .50. In VerticalShafts, 86% of the floor is unreachable from the biggest patch. The primordial law still passes -- you CAN get from arrival to departure -- but most of the floor is not part of that. That is precisely "not navigable" and it needed a new metric to see. New metrics: WalkableFloorAreaFraction, NumWalkableSurfaceComponents, LargestWalkableSurfaceShare. A floor you cannot cross is not a floor. Web references checked, per his suggestion -- we invented every metric in this project without once testing them against reality: NPS solution-cave and Mammoth Cave morphology, Lehman Cave dimensions (Talus Room 90x376 ft, 21,511 sq ft floor, 113 ft ceiling), Deep Rock Galactic cave-design notes, Team Cherry on Metroidvania maps. They support heterogeneous room+passage space with branches and shafts -- NOT a universal floor-to-volume target. So there is no single number to optimise, which is itself worth knowing. PART B -- Saved/VoxelForge/Showcase/index.html, 8 cards, 64 PNGs, fine renders (step 1, radius 64, centred on LargestComponentPoint), 0 blanks. Each card carries the exact PIE values to type in, because navigability is judged by walking: CrystalChamber seed 7331 idx 34 slot 1 Maze seed 0 idx 58 slot 1 FlatPlain seed 0 idx 4 slot 1 SurfaceWorld seed 0 idx 11 slot 2 FloatingIslands seed 0 idx 34 slot 1 TunnelNetwork seed 0 idx 61 slot 1 Underwater seed 0 idx 46 slot 1 VerticalShafts seed 0 idx 15 slot 1 All bComposerRollStructure = false. Selection searched seeds 0/7331 x indices 0-63, applied the three hard gates, then scored floor_area + .25*clearance + .10*largest_surface. Caveats kept honest: floor area is a sampled XY proxy, projected connectivity is not a 3D traversal proof, "best" means best within the searched range.

feat(composer): lateral REGIONS -- built, measured, and gated OFF
Jahni's own idea: "archetype could even mix within the same strate at some
point, tunnel network leading to a big chamber". An archetype becomes a
spatial REGION inside a strate, not a label on it.
Built by extending the mechanism that already exists rather than inventing
one: the stack blends VERTICALLY between strates, so regions blend the same
way LATERALLY. Deterministic jittered Voronoi sites on a 256-voxel lattice,
1-3 regions per strate from (seed, strateIndex), 24-voxel symmetric blend
band, per-chunk lookup cache. Parameters are never blended -- a shaft's
ShaftSpacing means nothing to a slab -- only the resulting DENSITY is.
Structural posts stay global and unconditional, so an invented region
cannot switch off the primordial law.
single-region path BIT-IDENTICAL to legacy, 256 probes, native + recipe
cross-boundary boxes 20 of 40, 199,800 voxels brute-forced, 0 VIOLATIONS
(every seam-spanning box correctly returned Mixed)
blend-band cost 663 ns vs 338 ns per voxel, over 16.0% of voxels
~1.15x field-weighted
survival 16/16 valid, non-vacuous, largest share >= .50
⛔ AND IT IS GATED OFF, because the seam breaks the one law that matters:
arrival -> departure across a region boundary passes 9/16 seeds, against
11/16 same-region controls in the same harness. Density blending alone does
not guarantee a player can cross a seam. A strate that mixes archetypes and
strands you at the boundary is strictly worse than one that does not mix.
VF_LateralRegionsAreShippable() returns false and the test ASSERTS THE GATE
IS SHUT while the rate is imperfect -- so flipping it without fixing
connectivity turns the suite red by design. The rate is a warning, not an
assertion: it is the measured state of an off-by-default feature, not a
regression in a live world, and a permanently red suite stops being read,
which is how real failures get missed.
Everything that ships is still hard-guarded: single-region bit-identity,
zero cross-boundary box violations, and every shipping-path law test
untouched.
The fix is an explicit CROSS-SEAM CORRIDOR CONTRACT -- a design decision,
recorded rather than made unilaterally. Codex diagnosed this correctly and
declined to tune the threshold, which was the right call.
Build clean, 29 succeeded / 0 failed, run and verified by me.

feat(composer): Tier 4c -- a season that can actually ship, with a veto page
The composer could invent, measure and show strates. What did not exist was an ARTEFACT a season could ship. Now it does. VF_ComposeSeason: generate N candidates -> measure -> reject failures -> select a descent sequence -> emit a JSON manifest + a review page. ⭐ THE PROPERTY THAT MATTERS: round-trip bit-identity. The manifest was loaded, every selected stack rebuilt, and 393,216 density samples compared BIT-IDENTICALLY. Re-composing the same seed yields byte-identical JSON. A manifest that cannot reproduce its own world is worthless, and that is the one thing that could not be assumed. Floats serialise as readable values PLUS exact IEEE bits, so a season survives a text round trip. Test season: 24 generated, 19 survived the hard gates, 6 selected. 18 not selected -- 4 vacuous, 1 primordial-law failure, 13 policy non-selections. 4 grounded, 2 outliers. EVERY selected slot passes the primordial law, asserted per slot rather than sampled. Selection policy is explicit, named and PROVISIONAL, because Jahni has not defined "good" yet and said so: "it'll be easier once i'm able to see the strates candidates." So no quality score was invented and presented as settled. The knobs are 75/25 grounded-to-outlier (outlier axis = distance from corpus centroid), adjacent-similarity threshold .20 with penalty 1.0, new-archetype bonus .10, new-recipe bonus .05, boss cadence every 5th non-terminal slot. All of them are his to turn. The veto is a review page in DESCENT ORDER -- the season read top to bottom the way it is played, not the survivor/outlier ordering the candidate sheet uses. Reuses VoxelStratePreview rather than a second renderer. Saved/VoxelForge/SeasonTest/season_0000_seed_9320/season_manifest.json .../review/index.html ⚠️ FIVE GAPS CODEX RAISED, recorded not buried: 1. §4's Tier A is strates PLUS passages; only the strate spine is persisted. Manager-generated passage geometry and content placement are not. 2. Authored fixed strates keep scalar vectors + asset paths, not every asset-level passage/biome/disturbance/content field. 3. Boss slots are MARKERS, not arena or content guarantees. 4. WorldRadiusVoxels == 0 is enforced as specced but contradicts a production bounded world -- Jahni's call, still unset by design. 5. Bit identity is proven for the same build and platform. A frozen season spanning engine versions needs an explicit schema contract. Real risk, since seasons freeze generation for months.

feat(composer): PROMOTION -- the corpus grows itself, and it did not collapse
Tier 5. §3.3's answer to Jahni's "I'd like the system to not rely at all on
the handmade ones": promotion does not REMOVE the authored seed, it dilutes
it. Every invented strate that measures well rejoins the corpus.
Five simulated seasons, 24 candidates each:
season corpus project/default/promoted survival spread
1 15 4/8/3 20.8% 0.869
2 20 4/8/8 54.2% 0.849
3 20 4/8/8 54.2% 0.849
4 21 4/8/9 45.8% 0.916
5 21 4/8/9 50.0% 0.916
Corpus 12 -> 21, of which 9 are discovered. Survival roughly doubles.
⭐ AND THE COLLAPSE RISK DID NOT MATERIALISE, which was the thing worth
measuring rather than assuming. Promotion selects survivors, and blending
survivors repeatedly can converge the corpus onto a narrow safe region --
the composer would get better at passing and worse at surprising. Spread
went 0.869 -> 0.916. It dipped and plateaued mid-run, but did not narrow.
Recorded honestly: seasons 3 and 5 promoted ZERO. The near-duplicate gate
(normalised metric distance < 0.20 over air, largest share, walkable,
feature scale, clearance) is doing its job, but it also means the corpus
saturates at this scale. Five seasons of 24 demonstrates the MECHANISM, not
§3.3's "season 5 blends 200 discovered ones" -- that needs the overnight
budget, not a test.
Safety: a promoted record is RE-MEASURED on load, never trusted. Verified by
corrupting a stored metric -- the loader discarded it and re-derived the
geometry. A stale or tampered record therefore cannot introduce an
unescapable strate into a future season, which is the one failure that would
matter. Provenance (project/default/promoted) is tracked and logged.
Codex's recommendation, and I agree: keep a small explicit OUTLIER QUOTA
among candidates that pass every hard gate. This run showed no collapse, but
survivor-only promotion keeps the long-term risk, and a quota costs nothing.
PART A: the fine ROI now centres on LargestComponentPoint instead of (0,0).
Blank fine renders 6/42 -> 3/42. The label now reads "largest open space",
not "strate centre" -- the image moved, so the caption had to.
Build clean, 27 succeeded / 0 failed, verified by me. WorldRadiusVoxels=0.

test(composer): the handmade corpus is load-bearing for QUALITY, not validity
Answers Jahni's standing wish directly: "in the best of both worlds, i'd like the system to not rely at all on the handmade ones." Three arms, same size, same measurement, same criteria: approach survival walkable mean feature-scale mean corpus blend (today) 13/16 81% 0.0661 92.3 naive uniform 7/16 44% 0.0126 64.6 constraint-sampled 7/16 44% 0.0129 31.4 ⭐ THE ANSWER IS NOT THE SURVIVAL RATE, IT IS THE QUALITY GAP. Constraint sampling produces VALID worlds -- it passes the primordial law more often than naive rolling (1 law failure vs 3) -- but the survivors are materially worse: ~5x lower walkable fraction and ~3x lower feature scale. A composer that emits technically-passing but uniformly mediocre places has not solved the problem. So the corpus carries something the declared constraints do not. §3.3 said independent rolling destroys the CORRELATIONS; stating those correlations explicitly recovers validity but not the tacit quality that authored vectors encode. That is worth knowing and it was not knowable by argument. ⇒ VERDICT: keep the corpus in production. Constraint sampling is a corpus-free BOOTSTRAP (it can seed a corpus from nothing), and PROMOTION (Tier 5) is the real route off handmade content -- dilution, not removal. Naive rolling is rejected outright. ⚠️ UNDER-POWERED, stated plainly: 16 candidates per arm, not the 256 the spec asked for -- the fixed 8M-cell box/law workload made 256x3 too slow to finish. The 5x walkable gap is large enough to be believable at n=16, but the survival rates (44% vs 44%) are not separable at that sample size. Do not quote these as precise. Authored-corpus audit, and Codex read it correctly: 3 of 12 vectors violate the proposed relations (DA_Strate3 room coverage 2.68 vs bound 0.35; Default_SurfaceWorld ground bound; Default_VerticalShafts shaft radius 5 vs roughness margin 5.875). That does NOT mean those assets are broken -- it means the new relations are conservative HYPOTHESES, not universal corpus invariants. Recorded as such. Box law held across all three arms: 768 proved, 673,486 voxels brute-forced, 0 violations. §6.2 did not reopen under corpus-free parameters. Also noted: "uniform within clamps" was underspecified in my spec -- many fields have no finite upper clamp. Both corpus-free arms use the same declared H-relative envelopes so the comparison stays honest. Build clean, CorpusFree green, WorldRadiusVoxels=0.

feat(editor): walk a composed candidate in PIE + why rooms read angular
PART B -- the thing Jahni asked for: "any way to test those in game?" A candidate existed only as measurements and PNGs. Now he can stand in one. Select the VoxelWorld actor in PIE -> Live Edit|Composer -> ComposerSeed / ComposerCandidateIndex / ComposerTargetStrateIndex / bComposerRollStructure -> click Apply Composer Candidate. The button and the automation tests call the SAME roll wrapper, which was the load-bearing requirement: a second roll path could drift, and then he would be judging a different world than the contact sheet describes. A determinism sample is logged on apply (seed, index, recipe, archetype, metrics, epoch, eight-point density verdict) so drift is caught the day it happens rather than in a month. Hazards handled, since this is the first composer code to touch the live runtime path: preflight materialisation before any live mutation, generation and decoration tasks drained, PassagesVersion bumped to invalidate thread_local caches, reuse of the existing RegenerateAllChunks / Epoch invalidation rather than a new path, no Initialize() or GeneratePassages() during apply (the re-entrancy trap), DiffLayer locks untouched, and custom recipes conservatively force ClassifyTile to Mixed. Scope is deliberate: a DENSITY-ONLY overlay. Layout height, authored passages, content, water and biome metadata stay from the existing slot; RebuildStrates() clears it. A full composed layout replacement needs a safe rebuild path that does not exist yet. Editor-only, verified: a Shipping build succeeds with the bridge excluded (96/96 actions), so §3.1's "offline only, never on a player's machine" still holds. ⚠️ UNVERIFIED BY DESIGN: a button cannot be tested headlessly and Codex was told not to claim it works. Jahni presses it and confirms the visual plus the "determinism=PASS" log line. PART A -- why rooms read angular, measured not guessed. One of three room shapes is VoxelSDF::RoundedBox: ShapeA = (.8 Rxy, .8 Rxy, .8 Rz) ShapeR = .25 Rxy so rounding is 31% of the horizontal half-extent but 78% of the vertical. Corners are rounded; the broad planar FACES survive. SmoothMin (blend 4) softens room/tunnel junctions not isolated corners; the cave warp bends geometry but preserves flat regions; roughness is surface-scale only. The name is accurate -- "rounded box" is not "blob". NOT ACTED ON. Jahni corrected his own read: the angular archetype is Maze (lattice source, rectilinear BY DESIGN and correct), and TunnelNetwork is "alright-ish". Codex's recommendation is recorded for if he ever wants it: ~5-10% boxes, 10-20% capsules, rest ellipsoids, or a larger ShapeR. Also closed REVIEW_FINDINGS EVoxelPassageType/Style as WONTFIX, enacting a 2026-08-16 judgement that recommended closure and was left open.

feat(preview): fine ROI renders + density contour -- the caves look like caves
Implements Codex's own recommendation from its critique, after it settled
the owner's two observations with evidence:
"hard walls" -> THE RENDERER. rg (room graph) re-rendered at step 1 is
rounded and organic. The hard edges were 4-voxel
sampling drawn nearest-neighbour. Fifth time in this
project that an alarming result was the instrument.
"like a maze" -> REAL AND CORRECT. lt (lattice) stays rectilinear at
step 1 because it IS a maze; 19 of 64 candidates use
that source.
"noisy" -> ALIASING. nr#22 speckle 7 solid / 1 air at step 4 ->
0 / 0 at step 1, broad shapes intact.
Built: an optional fine ROI pass at step 1, radius 64 (~1.8M cells, cap
2M), run only for the 42 coarse survivors, plus a deterministic density=0
CONTOUR rendered beside the filled view.
Both views are kept side by side on purpose. The filled view is honest
about what was sampled and carries the walkability evidence; the contour
is legible. Codex's line, and it is the right principle: anti-aliasing the
coarse image "would only cosmetically blur the evidence and could invent
geometry". Do not replace evidence with beauty.
Fine labels carry their own sample step and resolved window so a fine
image can never be mistaken for a coarse one, and a MaxCells refusal shows
in the page rather than looking like a failed render.
fine sampling 71.1 s · rendering 0.6 s · peak grid 9.34 MB
42 filled pairs, 42 contour pairs, 0 refusals, 424 image links, 0 missing
Codex corrected my spec twice in the critique, both sharp: a binary step-1
raster ALWAYS has one-voxel axis-aligned edges, so only persistent
LARGE-SCALE right angles prove boxy generation (my criterion would have
produced a false "it is boxy" verdict); and persistent speckle is not
necessarily a roughness modifier.
Roughness deliberately untouched -- its call to judge that only after fine
rendering exists, and it stands.
⚠️ KNOWN, next: the fine ROI is centred on (0,0), so a candidate whose
geometry sits elsewhere renders blank (candidate 003 is a flat sheet with
no surface in the ROI). FVoxelStrateMetrics already carries
LargestComponentPoint -- centre the ROI there instead.
Build clean, 25 succeeded / 0 failed, verified by me.

PART B: the preview. Jahni, asked what "good" means for ranking a season: "good is hard to describe, i believe it'll be easier once i'm able to see the strates candidates." So the ranking policy was blocked on this, not on more metrics. COMPOSER-NOTES §3.4 promised the preview comes nearly free once the measurement exists; collected. Per candidate, rendered from the grid the measurement ALREADY built (no second sampling of the world): a vertical XZ section and a plan XY slice, solid dark, air light, walkable cells highlighted, with a chunk scale bar so a corridor is distinguishable from a cathedral. Plus a self-contained index.html contact sheet of all 64 -- survivors first, outliers first within them, recipes, metrics, and every rejected candidate labelled with WHY (vacuous 3, fragmented 2, law failed 19). Saved/ComposerPreview/<runid>/index.html 64 candidates, 128 PNGs Two honesty rules are on the page itself, not buried in a comment: every number states the window that produced it (margin/step/Z span), and a 2D slice CANNOT show connectivity -- two regions that look joined in one slice may not be. Plan-Z is chosen by highest solid/air boundary-transition count, not hardcoded mid-height; a slab strate would otherwise render as a blank sheet. Codex flagged the ambiguity in my spec and picked correctly. PART A: bootstrap jitter for zero-spread fields. ±25% of a field's own magnitude when corpus spread is ~0, ±15% of measured spread otherwise, clamps last. Marked in code as a BOOTSTRAP for a starved corpus that promotion (Tier 5) should retire. 1,422 applications over 168 fields in the parameter roll; 6,848 over 107 in the structure roll. ⚠️ AND IT DID NOT BROADEN THE DISTRIBUTIONS. Feature scale 0-376 either way; walkable actually NARROWED (.389 -> .287). Codex's conclusion, and I agree: the measurement is INSENSITIVE to these fields, not merely corpus-starved. The reason is now obvious and worth writing down: the grid samples every 4 voxels, and cave DETAIL -- terraces, scallops, ribbing -- lives at 1-3 voxels. It is below the sampling resolution. A step-4 grid structurally cannot see feel; it sees size. So "vary the detail" and "score the detail" need different instruments, and the preview images inherit the same limit. Box proofs stayed sound under wider jitter: parameter roll 1,204 proved / 1,602,524 voxels / 0 violations; structure roll 659 proved / 877,129 / 0 violations. §6.2 did not reopen. fable-idea.md F1 ticked (measurement + preview).

feat(composer): cave FEEL is rollable -- 23 of 34 fields were live all along
Jahni: "we need to be able to have everything tuned, so feeling can be
quite different." So the 34 excluded terrain-detail fields had to be
settled -- they are the difference between varying how BIG a cave is and
varying how it FEELS.
Settled by EXPERIMENT, not by reading, because the exclusion rested on the
same kind of structural claim that produced the withdrawn fuse assertion
and the "99.95% void" reading. Sample GetDensityAt over a lattice, change
ONLY those fields, re-sample, per operation group:
LIVE (23 fields) terrace, layer-line, ribbing, overhang, cliff,
scallop, arch, dome, pinch -> now rolled
DEAD (11 fields) column, pit, chimney -> pre-baked into the chunk cache
from Definition->TerrainOperations, so the values in
FStrateGenerationParams are transport, not tunables
The call chain for the dead ones: BuildParamsFromDefinition returns only
the base params (VoxelStrateManager.cpp:1399); VoxelGenerator separately
reads Definition->TerrainOperations (VoxelGenerator.cpp:1099);
BuildChunkCache calls RoomOp->ApplyTo and pre-bakes pits/chimneys/columns
(VoxelCaveMorphology.cpp:1741).
⚠️ AND THE TRAP FIRED, exactly as specced against: these are native
unreflected fields, so REMOVING THEM FROM THE EXCLUSION LIST WOULD HAVE
ROLLED NOTHING. A knob that looks like it works and does not is worse than
an honest exclusion. An explicit jitter path was needed. This is why the
task was specced as an experiment with a liveness assertion (24 group/path
rows, 0 mismatches) rather than as a list edit.
⚠️ HONEST NEGATIVE: rolling detail did NOT materially broaden the measured
distributions. Feature scale 4-376 -> 0-376; walkable unchanged. All 17/17
TunnelNetwork/Underwater candidates activated live detail and every one of
the nine live groups appeared, so it is not that the fields are inert --
it is that most of them have ZERO CORPUS SPREAD, because the four authored
assets leave them at header defaults. Jitter is a fraction of measured
spread, and a fraction of zero is zero.
⇒ Real limitation, recorded not patched: "ranges come from corpus spread"
(§3.3) is right in principle and DEGENERATES on a homogeneous corpus. The
composer needs a bootstrap for zero-spread fields. Next.
Box verdicts with detail rolled: 1,228 proved, 1,634,468 voxels
brute-forced, 0 violations. Survival 59/64.
Recommendation recorded for later: roll terrain-operation parameter
STRUCTS directly into a transient candidate pool rather than corpus-ing
over assets -- there is exactly one such asset in the project, so an asset
corpus would starve like the strate corpus did.
Build clean, 25 succeeded / 0 failed, verified by me.

feat(composer): the structure roll -- 64 distinct stacks nobody wrote
Tier 4b. Until now the composer varied PARAMETERS within an archetype:
differently-sized caves. This rolls STRUCTURE, which is what makes a strate
a different KIND of place.
Per COMPOSER-NOTES §3.2: roll root polarity (rock+carve or void+fill) ->
a shape source legal for that polarity -> the conversion FOLLOWS from
polarity rather than being rolled -> k modifiers drawn from what the
CHANNEL DECLARATIONS say is legal, not from a hand-written list ->
structural posts appended automatically and not omittable.
64 distinct recipes of 64 (perfect structural diversity)
invalid recipes emitted: 0 (the roller cannot produce an
order the DAG validator rejects)
survival 46/64 (71.9%) non-vacuous 62, largest-share 60,
law pass 48
⭐ AND THEY ARE REAL PLACES NOBODY DESIGNED. Root polarity as a one-bit
identity lever, exactly as §3.2 predicted:
VF|r=vd/T|s=rg/T|x=fl/T TunnelNetwork's ROOM GRAPH rooted in void with
a FILL -- rooms become solid blobs hanging in
open space. air .978, feature scale 64.
VF|r=vd/M|s=lt/M|x=fl/M Maze's lattice corridors filled instead of
carved. air .938, feature scale 16.
RC|r=rk/V|s=sh/V|x=cv/V shafts carved from rock with a Maze modifier
set they never ship with.
Same parts, different worlds. That is the whole thesis of the op stack,
finally exercised.
⭐⭐ AND THE VERDICTS HOLD ON STACKS NOBODY VERIFIED:
489 proved (213 AllSolid, 276 AllAir), 2,071 mixed

feat(composer): it invents strates that work -- 59/64, and §6.2 is CLOSED
The corpus was starved: the loader followed the active settings pool and
found ONE vector, so all 64 candidates were bit-identical and every number
was a placeholder. It now loads every UVoxelStrateDefinition via the Asset
Registry (Saved/Autosaves and Saved/Cooked excluded -- including them would
silently weight the corpus toward whatever was autosaved last) plus the
per-archetype defaults from VoxelStrateTypes.h, which are themselves
hand-tuned known-good vectors. Blending stays WITHIN an archetype;
different archetypes read different subsets of the 73 fields.
⭐ THE COMPOSER WORKS. 64 candidates blended from real parents, every one
measured:
survival 59/64 (92.2%)
non-vacuous 60 · largest-share >= .50 60 · primordial law 63 · roll
failures 0
and they are genuinely different worlds, not one world 64 times:
air fraction .0137 -> 1.000
walkable .000 -> .389
feature scale 4 -> 376 voxels
archetypes TunnelNetwork, VerticalShafts, FlatPlain, CrystalChamber,
SurfaceWorld, Underwater, FloatingIslands, Maze
⭐⭐ §6.2 IS CLOSED, and it was the real risk. Box-verdict bounds were only
ever proved against the parameters Jahni typed; the whole worry was that
invented parameters would violate a bound nobody had checked -- silently,
leaving no geometry and no collision. Against ROLLED parameters:
1,224 boxes proved (549 AllSolid, 675 AllAir), 1,336 Mixed

feat(composer): the parameter roll -- infrastructure real, corpus starved
Tier 4a. The first piece of the composer that INVENTS rather than fixes. The design, from COMPOSER-NOTES §3.3: do NOT roll 73 parameters independently. The coherent region of a 73-dimensional space is a vanishingly thin sheet and uniform sampling never lands on it -- and independent rolling destroys the CORRELATIONS (room spacing <-> room radius <-> tunnel length) that make a vector coherent. So blend known-good vectors through the existing FStrateGenerationParams::Lerp instead: constraint satisfaction is free, because a convex combination preserves every relation holding in both parents. Min <= Max stays true because it was never broken. Built: FVoxelStrateCorpus (loads authored vectors, computes per-field spread), VF_RollStrateParams (2-3 weighted parents, convex blend, jitter by +-15% of each field's MEASURED corpus range -- not by the clamps, which are "don't type nonsense" limits, not "this makes a good world" limits), and VoxelForge.Composer.ParameterRoll. Determinism asserted by rolling twice and comparing every field. Exclusion list found by reflection, not assumption: StrateTopWorldZ and StrateBottomWorldZ (manager-owned runtime bounds) plus 34 terrain-op transport fields (TerraceStepHeight..PinchLength) that are copied in from room operators rather than being strate tunables. Bools inherit from the dominant parent; ints/enums use Lerp's existing snap. ⚠️ THE RESULT IS VACUOUS AND SAYS SO. 64/64 candidates "survived" -- but the corpus loaded ONE vector (DA_Strate3), so all 64 are bit-identical. 100% survival of a single point is not evidence of anything. The box- verdict check is vacuous too: 2,560 boxes, 0 proved, 0 voxels brute-forced, so §6.2 is NOT closed. The test emits a warning saying exactly this rather than reporting a clean pass, and no workaround was added to hide it. Four strate assets exist (DA_Strate1..4); the loader found one. Fixing the corpus is the next task -- with one parent there is nothing to blend, and every number above is a placeholder. Also owed: clamp metadata is editor-only, so the safety net needs a cook-time baked table before this ships. Nothing calls the composer from any runtime path (§3.1: offline, once per season, on a build box). Build clean, 23 tests / 0 failed (1 carries the deliberate vacuity warning), verified in VoxelM.log.

feat(opstack): EffectOverBox correct in ISOLATION -- the blocker is closed
COMPOSER-NOTES §6.1, titled THE BLOCKER, gated everything after it. A source writing only Sdf did not touch density, so it answered the box query ON BEHALF OF the converter that followed it -- fine when a human wrote and verified the pair, unsafe the moment the composer assembles a combination nobody checked. And the failure is the silent one: a tile wrongly proved uniform means no geometry, no collision, no error, and a player falls through the floor. FVoxelBoxHypotheses now carries FVoxelBoxSdfInterval. SDF writers publish their own [Min, Max]; replacement writers replace it, accumulating writers MinWith it; converters and detail ops consume the prior interval through a state-aware EffectOverBox. Each op answers only for itself and the fold composes them. Unknown, invalid, non-finite or unimplemented bounds force Mixed -- when in doubt the answer is Mixed, because a missed skip costs milliseconds and a false uniform costs a player. Bounds are SUPREMA of what Eval can produce, never the param named "max": FBM 1.5 (not 1.0), max(Min,Max) radius envelopes, warp sqrt(2), SmoothMin slack. [FLT_MAX, FLT_MAX] is the exact no-surface identity. ⭐ THE PROOF IS THE NOVEL STACK. Built a combination no shipping builder produces: ConstantVoid -> LatticeCorridorSource -> SdfRoughness -> SdfFill brute-forced 332,750 voxels across 256 boxes: 250 proved AllAir, 0 VIOLATIONS. If isolation is real an unverified stack must still be sound, and it is. That test -- not the refactor -- is the deliverable. Every archetype re-proved by brute force, 0 violations everywhere: Maze 112/256 · CrystalChamber 38/60 · Underwater 33/40 · FlatPlain 32/60 VerticalShafts 28/60 · FloatingIslands 15/60 · TunnelNetwork prod 9/40 TunnelNetwork dense 0/40 (correctly -- it really is all mixed) COST, reported not hidden: isolation gives up some skipping. TunnelNetwork production 12->9, VerticalShafts 32->28. Answering for yourself alone is strictly weaker than answering for a verified pair. The classifier stays materially useful and the trade buys safe composition, which is the point. Eval is untouched; equivalence tests bit-identical; no per-voxel box query. SurfaceWorld keeps its separate exact height/lattice classifier. Also: ⛔ WITHDREW the "corrective ops must be fused" claim from §3.2. FFloorBiasMod does NOT undo FCaveRoughnessMod -- it adds an independent NormZ^2 x FloorBias term to the ACCUMULATED density and never reads TotalRough. Not a correction, no fuse, no "corrects" dependency. The claim came from reading a name and a comment; one grep would have shown the ten Density-writing ops in between before the paragraph was written.

feat(opstack): every op declares its channels -- ordering becomes derivable
The composer must assemble stacks nobody wrote by hand. Today the legal order of operators lives in a human's head and in the hand-written builders. COMPOSER-NOTES §3.2: an op's legal position is fixed by which channel it READS and which it WRITES, so dependencies form a DAG and any topological sort of that DAG is a legal stack. EVoxelOpChannel names the two fields FVoxelOpSample actually carries (Density, Sdf) -- read from the struct, not assumed. All 29 concrete density ops declare reads, writes and additive/transformative, filled in by reading each Eval rather than trusting its name. The declarations are PURE VIRTUAL so a new op cannot silently omit them; the composer's safety depends on every op answering. A declaration nobody checks is a comment, so ValidateChannelOrder exists and VoxelForge.OpStack.ChannelDAG runs all eight shipping stacks through it. All pass: TunnelNetwork/Underwater 20 ops, Maze 8, VerticalShafts 9, FloatingIslands 8, FlatPlain/CrystalChamber 6, SurfaceWorld 6. Metadata is snapshotted in FVoxelOpStack::Add, so no declaration virtual is ever called per voxel -- ARCHITECTURE §8.10 respected. ⚠️ THE FUSE WAS DELIBERATELY NOT APPLIED, and the reason is the finding I asked for instead. §3.2 assumed FFloorBiasMod sits next to FCaveRoughnessMod. It does not: TEN ops separate them (Terrace, LayerLine, Ribbing, Overhang, Cliff, Scallop, Arch, RoomColumn, Dome, Pinch), and all ten read and write Density. Moving FloorBias would reorder the live density accumulation, and IEEE-754 addition is not bitwise commutative -- so the note's claim that fusing "leaves the field bit-identical" is false as written. That leaves a real open question for the composer, recorded not resolved: channel rules alone say any Density->Density order is legal, but they cannot express "this op CORRECTS that one". Either the fuse proceeds and accepts a changed field (legitimate -- peer determinism never required bit-identity across builds), or corrective intent needs its own declaration. Settling it needs FFloorBiasMod's actual math read, which is the next question I put to Codex. Build clean, 22 succeeded / 0 failed, verified in VoxelM.log.

fix(shafts): the primordial law holds -- 0 trusted negatives across 16 seeds
Closes the VerticalShafts bug. Two remaining failures were investigated
and neither was a broken world.
PART A -- my measurement window was binding, not the world.
The window was a square centred on (0,0) with a radius, while mouths sit
up to ~200 voxels out in arbitrary directions, so a box holding both was
mostly empty space paid for at full price. Seed 6 at step 1 needed
16,515,072 cells and blew the cap; fitted to the two mouths it needs
6,553,344 and measures fine.
seed 6 step 2 NOT_CONNECTED -> CONNECTED at doubled margin
seed 6 step 1 NOT_CONNECTED -> CONNECTED at doubled margin
seed 14 step 2 CONNECTED
seed 14 step 1 CONNECTED
A fitted box can cut off a route that detours outside it, so every
negative is re-run at doubled margin. 5 of 16 were binding negatives and
all 5 flipped. TRUSTED NEGATIVES: 0. There is no evidence of a single
unescapable strate in 16 seeds.
PART B -- the drainage tree has no orphans, and a third cause existed.
0 / 10,372 unreachable shaft paths (0% orphan rate)
16 strict local minima, all caught by the direct-spine fallback
neighbour fallback fired 0 times; emergency fallback 0
91.8% of non-largest components are smaller than one shaft volume --
they are roughness bubbles, not geometry
So a mouth could land in a noise bubble that is open but unreachable --
worse than useless, exactly the trap the law forbids.
VF_SuggestLandingPoint now returns the selected shaft AXIS, which is on
the drainage tree by construction.
⚠️ Codex found a third cause neither of us listed: tree capsules could
cross ledge bands, so a guaranteed connector could be blocked by a ledge.
Connector Z is now drawn from a deterministic ledge-free interval,
mirrored in the op stack.
⚠️ And an 8th error in my spec: "connect to any neighbour shaft" as a
fallback can create CYCLES -- a loop of shafts that drains nowhere and is
disconnected from the spine. The fallback must preserve strictly
decreasing origin-distance. Implemented that way.
per-archetype law 6/6 · box-verdict violations 0 · stack equivalence

feat(world): the XY edge seal -- the fourth structural invariant
VF_ApplyBoundarySeal was purely VERTICAL: it sealed each strate's ceiling
and floor and there was no horizontal equivalent, because until the depths
were bounded the world had no sides. The GDD now says "bounded, but
gigantic", so a player who walked far enough reached unterminated
generation running off into nothing.
Built as a FORCING op, appended automatically and not author-omittable, so
an invented strate cannot forget its own edge. Because a forcing op proves
AllSolid in its band, the outer shell also becomes free to skip in tile
classification -- correctness and a perf win from one change.
order spine -> vertical seal -> passage carving -> XY EDGE SEAL
-> disturbances -> diff
A near-rim passage may pierce a vertical seal; the XY seal runs after and
wins. A passage must never punch a hole through the world's edge.
ClassifyBox/ForcedMarginOverBox proved via the closest AABB radius with a
one-voxel margin: 8 boxes proved, 1 tile proved, 600 voxels brute-forced,
0 violations. FXYEdgeSealOp is IsXYPure. Max rim discontinuity .187 against
a 1.0 threshold -- a ramp, not a cylinder wall.
⚠️ WorldRadiusVoxels DEFAULTS TO 0, and that is deliberate. Codex flagged
that DA_Settings and BP_VoxelSettings predate the property and so do not
serialize it -- they inherit the C++ default silently. A default of 8192
would have walled in every existing world on next editor open with nothing
in the asset to explain it. 0 is a bitwise no-op (45 interior comparisons
against the unbounded path prove it). The GDD's intended ~8192 is a value
to set in the asset, deliberately, once. Documented at the declaration.
Codex found four spec errors, three of them mine: VF_ApplyBoundarySeal
lives in VoxelDensityPrimitives.h not VoxelCaveMorphology; the asset
default trap above; and my "density increases through the band" wording
contradicts the MC sign convention (solid is more NEGATIVE) -- the test
measures increasing solidness.

fix(measure): a blocked route is not a disconnected pair
VF_AreConnected took the shortest coarse BFS route, re-walked it at full resolution, and on hitting a wall returned false and gave up -- never looking for another way round. That is a false NEGATIVE, and it was inflating the failure count of a bug we were actively trying to fix. On refutation it now excludes that specific coarse step and re-searches, up to a bounded budget (16). Outcomes are distinguished honestly: Connected a route survived full-resolution verification NotConnectedAtThisResolution no coarse route remains after exclusions CoarseLiedBudgetExhausted UNKNOWN -- routes kept being refuted The third is deliberately NOT folded into either other verdict. Collapsing "unknown" into "disconnected" is precisely what misled us. arrival->departure 7/16 -> 14/16 All 7 former COARSE_LIED became CONNECTED. arrival->spine 15/16 connected departure->spine 15/16 connected per-archetype law: 6/6 applicable routes pass Retries needed are small -- max 3 per query, 0 budget hits -- so 16 is generous rather than load-bearing. Runtime slightly IMPROVED (45.3 -> 44.9 s on the 16-seed sweep) because a satisfied query stops early. The false-POSITIVE guard is untouched and is now stronger in meaning: every Connected still requires a fully re-walked, air-verified route, and it now says "this specific route is open" rather than "the first route I tried was open". The controlled wall still returns BudgetExhausted after exactly 16 retries, and a repeat query is bit-identical in verdict, snap flags and retry count. ⚠️ REMAINING: seeds 6 and 14 are genuinely NOT_CONNECTED. Real or a step-2 resolution limit is not yet settled -- refine before touching generation again, per COMPOSER-NOTES §13. No generation, placement or parameter changed. Verifier only.

docs(composer): record what measuring the world actually found
The notes described Tier 1 as done and had no record of today. Adds §13 (Tier 2 built, and the three artifacts that looked exactly like findings), §14 (the VerticalShafts bug end to end -- three bugs wearing one coat), §15 (working notes that cost something), and corrects the Tier 1/Tier 2 entries in §7. The rule worth keeping, because it held three times out of three: when a measurement reports something alarming, SUSPECT THE MEASUREMENT FIRST. "FlatPlain is 99.95% void", "5 of 15 endpoints disconnected" and "7 of 16 seeds fail" were all method, not world. Also recorded: the two guard directions are not symmetric (a false positive drops a player through the floor; a false negative merely sends you fixing healthy code), percolation is a phase transition and not a knob, and Tier 1 shipped half built in a way only a connectivity measurement could reveal.

fix(passages): aim the UPPER mouth too -- Tier 1 was only half built
VF_SuggestLandingPoint was called exactly once per passage, for the LOWER
mouth. The upper mouth fell out of the control-point chain with no landing
query at all: Tier 1 fixed where a player ARRIVES and never touched where
they DEPART. That predicted the measurement exactly -- departure->spine was
0 connected across all 16 seeds.
The ring proxy could never have caught this. It checks each mouth for open
space individually, and an unaimed mouth still has open space around it,
because the passage tube carved some. It took a connectivity measurement.
Each mouth now queries ITS OWN strate independently, which is what keeps
the layout a set rather than a sequence -- passage i never reads passage
i-1, so LayoutOrderIndependence stays green. Seed contracts kept unmixed;
SurfaceWorld still refuses; a declined query still preserves today's
placement rather than degrading it.
departure->spine 0 -> 9 connected of 16
arrival->departure 4 -> 7 of 16
aiming coverage upper 6/7 and lower 6/7 mouths now aimed at
generator-confirmed open space
⚠️ ACCEPTANCE STILL FAILS at 7/16, and the breakdown says why it is not
what it looks like:
arrival->departure: CONNECTED 7, NOT_CONNECTED 2, COARSE_LIED 7
Only TWO seeds are genuinely disconnected. Seven are COARSE_LIED -- the
coarse BFS found a route and the full-resolution walk hit solid on it.
VF_AreConnected checks that ONE route and gives up, so a blocked candidate
is reported as failure even when another route exists. That is a false
NEGATIVE in the verifier, and it means this acceptance number probably
understates the world. Next task fixes the measurement, not the world.
Codex was killed mid-flight by a session teardown, so the edits arrived
unvalidated; I built and ran the suite myself rather than assume.

feat(shafts): a drainage tree -- the field goes from 22% to 97% connected
The plateau was the tell. Roughness changed the component COUNT (it
manufactures noise pockets) but the giant component sat at ~0.22 in every
variant, and widening connectors past the proven roughness bound barely
moved it. That is a random graph below its percolation threshold: 0.6
sites, 0.35 bonds, and a 1.6-cell pair cutoff that drops many neighbour
pairs once jitter spreads them 1.7 (orthogonal) to 2.4 (diagonal) cells
apart.
So the lever was topology. Every shaft now emits a deterministic connector
to the nearest shaft STRICTLY closer to the origin, so chains drain inward
and terminate at the spine. The probabilistic connectors stay as texture
and loops -- the tree guarantees you can get out, the noise keeps it from
reading as a diagram.
Deliberately NOT tuned: raising CrossConnectChance/ShaftDensity/the cutoff
toward the percolation threshold buys a world connected at one seed and
shattered at the next, which is exactly the 1-in-16 behaviour we had. A
phase transition is not a knob.
seed 1337 components 30 -> 17, largest share .220 -> .975
16 seeds spine is the largest component in 16/16 (was 8/16)
largest share .58 - .9999
Seam safety, because a parent computed from a 3x3 window would differ
between chunks and the connector would exist in one and not the other:
collect over 7x7, emit only for the inner 3x3, whose 5x5 candidate windows
are then fully contained. 154 seam probes per path, 0 mismatches.
Box verdicts re-checked against the new air: 27 proved, 33 mixed,
0 violations. Stack mirror bit-identical over 20,000 samples.
Perf: 1.634 us forced rebuild, 0.100 us hot call -- the 49 rolls happen
only on cache rebuild, never per voxel.
⚠️ ACCEPTANCE STILL FAILS: arrival->departure 4/16 (was 1/16). Reported,
not tuned. With 97% of the air in one component, two mouths that both land

is placement, not topology. Next.

feat(shafts): the spine joins its neighbours -- necessary, not sufficient
Jahni chose: make the (0,0) column join the shafts it passes, so VerticalShafts behaves like the other seven archetypes. Built, and it works as far as it goes -- the spine is now the LARGEST air component in 13 of 16 seeds (share up to 0.81, was 0.096 and never largest). ⚠️ IT DOES NOT MEET THE ACCEPTANCE CRITERION. arrival->departure is still 1/16. Reported as a failure rather than dressed up, because the criterion was the measured law, not "the code was written". The test now prints ACCEPTANCE arrival->departure: FAIL (1/16 seeds pass) so it cannot be quietly forgotten. Why it is insufficient, and it is structural: the spine only joins its own 3x3 cell neighbourhood, while passage mouths land 60-200 voxels from (0,0). The departure network is unreachable from the spine in all 16 seeds. Joining the hub to its neighbours does not help if the rest of the graph never reaches the hub. Part A diagnosis (seed 1337, margin 0, step 2, radius 192): baseline 30 components, largest .220 roughness 0 17 components, largest .226 connector radius 8 29 components, largest .229 H1 is real but partial: roughness fragments the space (13 of the 30 components are noise pockets), yet widening connectors past the proven roughness bound barely moves it. So roughness is NOT what severs the network -- the largest component sits at ~0.22 in every variant, which is the signature of a graph below its percolation threshold. The lever is topology, not radius. H2 (the hardcoded 1.6 pair cutoff) went untested. Implementation notes: the spine is added ONLY as a connector endpoint, not as a carving shaft -- VF_ApplyOriginSpine remains sole owner -- and is excluded from ledge placement. Spine connectors use radius 6.625, above the proven roughness supremum of 5.625 (sup|FBM| = 1.5, not 1.0). SpineRadius is threaded through BuildVerticalShaftStack, not hardcoded. Op-stack mirror bit-identical over 20,000 samples, 0 box-verdict violations. LayoutOrderIndependence green. Build clean, 19 succeeded / 0 warnings / 0 failed.

test(measure): the spine is the backbone in 7 of 8 strates -- and not in
VerticalShafts Diagnosis only. No generation or placement changed. The hypothesis was that the (0,0) spine (OriginSpineRadius 14) is the universal connector, so "can this mouth reach the spine" would be the real primordial-law test. Measured at margin 0, step 2, radius 192: strate spine share largest? arr->spine dep->spine TunnelNetwork 0.979 YES CONNECTED not connected FlatPlain 1.000 YES CONNECTED CONNECTED CrystalChamber 1.000 YES CONNECTED CONNECTED Maze 0.997 YES coarse-lied CONNECTED SurfaceWorld 1.000 YES CONNECTED CONNECTED VerticalShafts 0.096 NO not conn. not connected FloatingIslands 1.000 YES CONNECTED CONNECTED Underwater 0.999 YES CONNECTED n/a The spine forms one uninterrupted open interior run in 8/8 strates, and holds essentially ALL the air in 7 of them. VerticalShafts is the lone anomaly: the spine punches through as an isolated column holding 9.6% of the air and is NOT the largest component. So the archetype has three mutually unreachable things -- the spine, the arrival network, the departure network. It has no lateral connectivity at all. Over 16 seeds: spine open 16/16, spine largest only 8/16, arrival->spine 1 connected, departure->spine 0 connected. Neither extreme was right. The spine is not a universal connector, but it is far from irrelevant: it is the de-facto backbone everywhere except here, which reframes the bug as an ANOMALY to bring in line rather than a missing feature to invent. Ordering hazard confirmed on the record: making passage i depend on passage i-1 would break LayoutOrderIndependence. Both candidate fixes avoid it, because the spine is a fixed deterministic anchor that two mouths can target independently. Build clean, 19 succeeded / 0 warnings / 0 failed.

test(measure): VerticalShafts breaks the primordial law in 15 of 16 seeds
The margin is exonerated. Every earlier run excluded 8 voxels at each strate boundary, and voxels 4-8 of those are ordinary interior, not seal -- the same window mistake that produced "FlatPlain is 99.95% void" at margin 32. So the query was re-run at margin 0, 2, 4 and 8. All four stay negative; margin 0 includes the seal itself and still reports negative. (The implementation had clamped explicit margins to >= 1, which made the margin-0 check impossible; Codex found and fixed that.) Diagnosis -- this is not a near-miss wall: arrival LowerPoint (65.8, 95.8, -1047.25) departure UpperPoint (88.4, -104.6, -991.58) XY separation 201.7 voxels (~50 m), Z delta 55.7 arrival component 22,531 cells (22.0% of air) departure component 21,621 cells (21.1% of air) nearest approach between the two components: 135-179 voxels Two large, healthy, entirely separate shaft networks half a strate apart. Nothing to breach; the archetype has no lateral connection at all. 16-seed sweep: 1 pass, 15 fail. Not one unlucky world -- structural. So: descend into a VerticalShafts strate and you probably cannot reach its exit. This is the "live hole in the shipping game" COMPOSER-NOTES Tier 1 predicted, now measured instead of assumed. Stated precisely, because it names the fix: VF_SuggestLandingPoint makes each mouth land in open space, but NOTHING makes the two mouths of one strate land in the SAME open space. New: VF_DiagnoseConnectivity returns component sizes and the spatial separation between the two mouths' components, so a near-miss and a never-meant-to-connect read differently instead of both being "false". No generation change, no threshold tuning. The fix is a design decision. Build clean, 19 succeeded / 0 warnings / 0 failed. Sweeps 3.4 s + 6.9 s.

test(measure): the VerticalShafts disconnection is real, not a coarse lie
Our guard was one-directional. FullResolutionPathIsAir catches the false POSITIVE -- coarse says joined, reality says walled -- which is the dangerous direction for safety, so we built it first. The opposite error was unguarded: a corridor narrower than SampleStep falls between sample points and vanishes, so connected regions read as separate. That is exactly what a network of narrow vertical shafts would fake at step 4. Refinement sweep, radius held constant for the controls: step 4 / r256 NOT_CONNECTED 57 comp largest .119 458,752 cells step 4 / r192 NOT_CONNECTED 32 comp largest .220 258,048 step 2 / r192 NOT_CONNECTED 27 comp largest .220 2,064,384 step 4 / r128 NOT_CONNECTED 20 comp largest .291 114,688 step 1 / r128 NOT_CONNECTED 11 comp largest .303 7,340,032 Both fixed-radius pairs stayed negative, so neither the step nor the radius explains it. At one-voxel sampling the arrival and departure mouths are still in different air components. VerticalShafts is a live primordial-law violation: a player descends into it and cannot reach its exit. NotConnected is renamed NotConnectedAtThisResolution and documents its own limit at the declaration, so a bare negative can never again be read as proof. CoarseLied names one direction; this names the other. Sweep split into VoxelForge.Generation.StrateConnectivityRefinement so the fast test stays fast. 4.4 s. The MaxCells refusal path was exercised and still refuses. Build clean, 19 succeeded / 0 warnings / 0 failed.

fix(measure): ask the primordial law the right question
Three defects, two of them mine. 1. The anchor was a guess. LargestComponentAnchor() returned a hardcoded point near the (0,0) spine and the comment admitted it, so NOT_CONNECTED meant "not connected to a guessed point". The flood fill already knows the answer; it now returns LargestComponentPoint (tie- broken by lowest cell index, so it stays deterministic), LargestComponentCells and NumComponentsAtLeast1Pct. 2. "Connected to the largest component" is NOT the primordial law. The law is that a player must not descend into a place they cannot leave -- a question about MOUTHS. A strate can be 57 disconnected shafts and be fine, provided the shaft you arrive in is the shaft you leave from. The test now asks arrival -> departure per strate: the LowerPoint of the passage arriving, to the UpperPoint of the passage departing. 3. A false verdict and a true one were indistinguishable. VF_AreConnected returned false both when no route existed and when the endpoint's own coarse cell sampled solid -- and a passage mouth is a carved tube whose cell centre lands in adjacent rock easily. It now returns EVoxelConnectivityResult and snaps to an adjacent air cell first, reporting the repair. RESULT: the earlier "5 of 15 endpoints disconnected" was an ARTIFACT of the guessed anchor plus the wrong question. Corrected: 13 of 15 connected, 0 StartCellSolid, 0 GoalCellSolid. One real finding survives. arrival -> departure passes for 5 of 6 applicable strates; VerticalShafts FAILS -- its arrival mouth is in the largest component, its departure mouth is not. NOT yet reported as a bug: a coarse grid can falsely SEPARATE as well as falsely join, and a connecting corridor thinner than SampleStep vanishes. Next task settles it at a finer step. Also noted: GetPassages() contains a self-referential surface entry (0 -> 0), excluded from the chain law. Build clean, 18 succeeded / 0 warnings / 0 failed, verified in VoxelM.log.

fix(measure): measure the strate, not the band above its floor
The window excluded a whole chunk (32 voxels) at each end to avoid a 4-voxel seal band -- 8x too much. On 4-chunk strates that discarded half of every strate, floor included, so the pass was measuring the open air above the ground and calling it the strate. The margin now derives from the seal that actually exists: ceil(2 x BoundarySealThickness), clamped to [1, height/4], overridable via InteriorMarginVoxels. The fixture resolves to 8 voxels. FlatPlain/CrystalChamber walkable fraction: 0.00044 -> 0.0578, ~132x. The "99.95% empty void" reading was the window, not the world. Metrics now carry ResolvedMarginVoxels, SampledMinZ and SampledMaxZ, and the test prints them. A measurement that does not state the volume it measured is exactly how the previous defect survived review. VerticalShafts largest-component share rose only 0.074 -> 0.119 across 57 components: the window explained part of the swiss-cheese signal, not all of it. That one is at least partly real. Coarse-lie guard still load-bearing: 24 routes checked, 3 refuted at full resolution (was 21 / 2). Build clean, 18 succeeded / 0 warnings / 0 failed, confirmed in Saved/Logs/VoxelM.log rather than from the agent's summary.

feat(measure): one grid, one flood fill -- the strate measurement pass
Tier 2 slice 1 from COMPOSER-NOTES.md 3.4. A read-only, deterministic, headless measurement of a built strate: sample a coarse grid once, flood-fill the air once, derive every metric from that same grid. What it answers today: air fraction, air component count and largest component share (the swiss-cheese signal), walkable fraction, median feature scale, median vertical clearance -- and whether two points are actually connected. The connectivity verdict is the point. Coarse sampling LIES about it in the dangerous direction: a wall thinner than the sample step vanishes and two sealed caverns read as joined. So VF_AreConnected recovers the actual BFS route and re-walks that one corridor at one-voxel spacing; a true verdict is never returned on coarse evidence alone. It fired: 2 of 21 routes were coarse false positives. The test carries a negative control, because a green suite that cannot fail is what hid the last defect. Two of them, in fact: a direct probe of the known-solid inter-strate gap (AirFraction 0.00042), and -- Codex's improvement on the spec -- a diff-layer box filled solid and measured through VF_MeasureStrate itself, so an inverted sign is caught end to end rather than around the function under test. Build clean, 18 succeeded / 0 warnings / 0 failed. KNOWN, fix in flight: the interior window excludes a whole chunk (32 voxels) at each end to avoid a 4-voxel seal band -- 8x too much. On the fixture's 4-chunk strates that discards the floor, so the reported FlatPlain/CrystalChamber air fractions of 0.999 describe the open band above the floor, not the strate. The engine is right; the window is not. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Bp7FxoQcSoiuhxjuLr6aBM |

feat(strate): passages aim at open space -- for half the archetypes, measurably
Tier 1. GeneratePassages placed every passage at a random angle, distance and reach, never consulting the destination strate. The carved tube is air by construction, so nothing looked wrong -- but whether the lower mouth joined the destination's connected cave space was luck. A player could descend and arrive in a sealed pocket. The primordial law was a hope. VF_SuggestOpenPointZ is a pure free function of (archetype, params, seed, XY): no operator stack, no StrateManager, no cache. That is deliberate. This runs inside Initialize, where the layout is half-built and LayoutVersion is in flight, so anything holding a manager pointer there is a re-entrancy trap. Coverage is four archetypes of eight, and the number is the deliverable: 7 passages, 3 aimed at generator-confirmed open space with 48/48 ring samples air, 4 falling back. The hole is not closed. It is measured, where this morning it was invisible. Two corrections from Codex, both mine and both would have shipped confident nonsense: room placement is seeded by MakeStrateSeed, not the passage salt, so my version would have queried a cave graph that does not exist; and slabs need the world seed because that is what GetSlabDensity uses. And one of mine caught in review: the first test sampled GetDensityAt at the mouth and asserted air, which is true by construction because the passage carve is a structural-post invariant. It could not fail. Replaced with a 16-point ring outside the carve radius requiring 8/16 air -- a proxy for connectivity, not a proof. The proof is a flood fill, which is Tier 2. Logging: my first spec asked for a per-passage warning on fallback. It fired 572 times and turned 14 clean tests yellow, which is precisely the anti-pattern OPSTACK-HANDOFF.md warns about -- a warning that always means "this is fine" teaches people to ignore warnings. Now one sorted Log line per layout build. Built clean, suite green: 17 succeeded, 0 with warnings, 0 failed.

feat(strate): the layout is a set, not a sequence -- and the suite is green
Tier 0. Reordering Settings->StratePool in the editor used to change every world in the game, because Initialize Fisher-Yates shuffled the array in editor order. The pool is now sorted by stable soft-asset path before the shuffle, so the layout is a pure function of (seed, pool contents as a SET). The selection algorithm itself is untouched -- same Fisher-Yates, same cycling, same FixedStrates handling, same Z ranges. Sorting by pointer would have looked right and been load-order dependent, which is the trap here. GeneratePassages walked one sequential FRandomStream across every strate, so changing an early connection count shifted every later passage. Each draw is now a salted VoxelHash of (seed, boundary index, connection index), with the distributions preserved exactly -- ToFloat01 returns [0,1), so Lerp(Min,Max,t) reproduces FRandRange precisely. Codex implemented it and caught a real flaw in my spec: I asked for a test that permutes the pool and asserts the passages match, but once the layout is order-independent that test cannot fail whether or not the passage fix works -- the layout comes out identical, so even the old sequential stream would agree. It added the perturbation that actually bites: change an early connection count and verify every later boundary keeps its own values. It also contradicted me on passage type being randomly drawn. It isn't, and it preserved that. Built VoxelMEditor clean, then ran the suite headless: 16 succeeded, 0 failed, 0 not run. That also closes the thread OPSTACK-HANDOFF.md left open -- |

docs(composer): split the transcript -- notes become generator-only
CLAUDE.md says each doc has one job and they must not duplicate. After GDD.md
landed, COMPOSER-NOTES.md and it both held the death loop, the city tiers and
the economy -- and duplicated documents drift until neither is authoritative.
So the notes are now the engineering document and nothing else: the vision and
its correction, what the game *requires* of the generator (constraints only,
pointing at the GDD for why), the composer itself, the manifest, naming, every
code finding and hazard, the build order, and the corrections nobody should
re-derive. 1561 lines down to 527, with the game design replaced by pointers.
Two sections earn their place on their own. Section 6 is the verified code
findings, including the one that blocks free composition (EffectOverBox answers
for the source+carve pair, so an op's box verdict is only correct in the stack
it shipped in) and the primordial law's live hole (GeneratePassages never
consults the destination strate's layout, so a passage can open into a sealed
pocket). Section 8 is the list of corrections that cost real time: Phase 3 is
reopened, Jahni does not want to author strates either, peer determinism never
required matching the old system.

docs: a game design document, distilled from the transcript
COMPOSER-NOTES.md is a conversation: chronological, with my wrong turns kept on purpose so nobody re-derives them. That is the right shape for us reading it back and the wrong shape for anyone else, including Codex. GDD.md is the other half -- the decided state without the journey. Seventeen sections covering the premise, the core loop, the city, the depths, a strate, descending, the economy, death, housing, the verbs, the season, the community layer and the opening. Every section separates what Jahni decided from what is still open, and design that is mine rather than his says so, so nothing reads as settled that isn't. Written deliberately plainer than the notes: prose rather than dense tables, because a design document that only its authors can read has failed at the one thing it exists for. Also records why the file is in the wrong folder. This is a document about the game, and most of it -- the city, combat, the economy, seasons -- is nothing to do with VoxelForge. It lives in the plugin because the plugin is the only part of the project under version control. It should move to the project root once that becomes a repository.

docs(composer): the depths regenerate, the city does not -- game design session
Second design session. Started on the composer, ended up with the whole game's economic loop, and one terminology fix that was overdue. The loop, closed: the surface is a sky island or an unclimbable mountain, so resources must come from below; the depths supply them; the resources build the settlement; the settlement enables deeper descent. The settlement is communal, identical for everyone, and permanent -- a season advances it one tier (camp, village, town, city). So the wipe means something beyond freshness: the world is impermanent, the civilization is not. We lost our maps, but we built a town. I had that arc backwards and it is marked as such in the file, along with the vocabulary that caused it: "the world" was being used for two different things. The depths are what VoxelForge generates and what regenerates each season; the city is a plain Unreal level, permanent, and entirely outside this plugin. That distinction is now pinned at the top of the notes. Also settled: no bottom, boss strates every ~5 as intermediary gates, gear stats capped around depth 30 with deeper loot buying better rolls and unique materials rather than bigger numbers, materials tagged by difficulty tier rather than depth so their location is rediscovered every season, and death leaving a possessed corpse that copies your weapons without taking them -- a mirror match that self-balances at every tier forever, provided the copied gear is never lootable. Two design records worth keeping: the manifest is two things (a tiny stored spine and an infinite hash-addressable field, where the ID encodes the position so resolving it needs no table), and the opening cinematic -- civilization emerged from the depths, humans crystallized in the first artificial strate -- justifies the authored/generated seam in fiction. A player who senses strate 1 feels different from strate 2 is reading the story correctly, not spotting the join.

fix(world): the voxel field is in ACTOR space -- make every entry point agree
The city's hole is not at world (0,0), so the AVoxelWorld actor has to move.
It couldn't: the plugin was only HALF actor-relative, and had been for a long
time without symptoms because the actor always sat at the origin.
Already correct: GetBiomeAtWorldLocation, GetVoxelSurfaceHeightAt,
UpdateDecorations, UpdateLandmarks, UpdateWater, UVoxelDensityVolume::Update,
the passage debug draw, the clipmap material.
Not correct: the streaming centre, the streaming anchors, all six carve/fill
entry points, GetStrateAtPosition, and UVoxelAtmosphereManager::UpdateForPlayer
-- whose own comment documented the assumption out loud ("actor at
origin/identity"). Carving would have landed offset; the strate lookup would
have been quietly wrong by the actor's Z.
The trap worth recording: because the content managers already convert
internally, converting PlayerLastPos once at the source would have DOUBLE-
converted four call sites. The fix has to be per-boundary. That was only
visible after reading each consumer -- the estimate before that read was wrong
in both directions.
WorldToLocalCm / WorldToLocalVoxel / LocalVoxelToWorld are now declared as the
only sanctioned boundary between Unreal coordinates and voxel coordinates, and
the real deliverable is the invariant next to them: no `/ VOXEL_SIZE` applied
to a parameter named `World*` outside those three functions. A grep can check
that. The risk was never a missed site among the ones found -- it is the next
one nobody notices.
Also adds a translation-only guard in BeginPlay. Tiles, ClassifyBox verdicts,
the clipmap window, culling and streaming distance all assume world-axis-
aligned boxes; a rotation or non-unit scale breaks that structurally rather
than gracefully, so it logs an Error naming what was set.
With the actor at the origin every conversion is identity, so this is a no-op
until the actor actually moves. Built and confirmed working.

test(strate): the X-macro guard -- a warning in prose does not fail CI
FStrateGenerationParams::Lerp blends the hand-written VF_STRATE_PARAM_FIELDS list, not the struct. Add a field to one and not the other and it compiles, tests green, and silently takes its default inside every Gradient/Interleaved transition band -- terrain that changes shape at the boundary and nowhere else. CODEMAP has warned about this in prose for a month. The test expands the X-macro a third way (after LERP and SNAP), into a list of names, and diffs it against the struct's UObject reflection. No fixture, no world -- a shape test, instant. GExemptFieldNames is empty on purpose: every reflected field is covered today, so an exemption has to be written down as a decision rather than happening by omission. The stakes rise with the world composer, which intends to invent parameter sets through this same Lerp: a missing field would then be constant across every invented strate, with nothing to notice it by. (Its CODEMAP §3.12 row lands in the following commit, which also touches that file for an unrelated reason.)

docs(composer): the composer runs once per season, offline -- so it can take all night
Second half of the design session. The realisation that resets the whole cost budget: everyone shares one seed per season, so there is exactly one world per season and the composer never runs on a player's machine. It runs once, on a build box. Not "fast enough for a loading screen" -- "runs overnight". It can generate a thousand candidates, keep eight, and let Jahni veto the season before it publishes. What ships is the seed plus the chosen parameter vectors. The measurement pass itself is one coarse grid and one flood fill, producing one feature vector that serves validation, danger and rarity at once. Noted the one place coarse sampling can lie -- a wall thinner than the sample spacing makes sealed spaces look connected, which would pass the primordial-law check on an impassable strate. Coarse to find the route, full resolution to confirm it. And the answer to "how do we ever judge what's good": the judge is the corpus, not a model. Good never gets defined, only collected -- strate-level thumbs up/down, player behaviour, and best of all where players choose to snapshot their home, which is an ungameable "I love this place" that costs nothing to collect. Known risk written down: promote only what you already liked and the system converges on a comfortable middle.

docs(composer): the system should invent worlds -- design session notes
A long design conversation, written down as it happened. The headline: the op stack's "Phase 3" is REOPENED. Asked what the world was missing, Jahni described exactly it -- the system assembling worlds from data assets and a seed -- so the 2026-08-16 handoff's "do NOT start Phase 3" is superseded. Then a correction that moved the whole thing a level deeper: he does not want to author strates either. The system must INVENT them. He authors raw content (operators, meshes, materials, sounds, creatures) and tags it; everything above that is composed and measured. Decided along the way: worlds are wiped every 6-12 months, which dissolves the "generation is frozen forever once public" problem -- generation is frozen only within a season. Shared player builds are blueprint structures, vote-ranked. Housing is an instanced level built from a snapshot of land the player chose. Danger is depth x a per-strate multiplier, not a sort. Every strate has a findable entrance and exit -- built first, generated around. The range problem turned out cheap: don't roll 73 parameters independently (that is what makes mush), blend known-good ones with FStrateGenerationParams::Lerp, which already exists and already blends the whole field set. Ranges come from the spread of the existing corpus, not from authored numbers. Verified against the code: the X-macro is in sync with the struct, only Alpha differs. Recurring mechanism, arrived at three separate times: measure, don't declare -- and promote what measures well back into the corpus, so the system's vocabulary grows from its own history.

docs: close the operator stack -- handoff rewritten in plain language
Jahni built the last two commits and the game looks fine. Closing the thread. OPSTACK-HANDOFF.md fully rewritten. The old one had become a private dialect -- "you've started using very unique terminology, i have NO idea what you've been doing" -- which is a failure of the document, not the reader.

test(tunnel): a warning that always means "this is fine" is noise -- demote it
Jahni asked whether a "warning stage" he had been seeing for several sessions meant something was broken. It did not: the only Warning in that run is the tunnel test's "[dense fixture] No tile was proved", whose own text explains that 0 proved is the EXPECTED and correct result there -- cull spheres cover the dense fixture ~3.6x, so no box can be outside all of them. Test passes, density bit-identical, all coverage non-zero, violations 0, and production defaults reports 11 proved / 14641 voxels / 0 violations right below it. But a warning that fires every run and always means "fine" trains the reader to ignore warnings, and this one quietly worried him across several sessions. RunTileScan now takes bZeroProvedIsExpected: AddInfo on the dense fixture where zero is the only possible answer, AddWarning on production defaults where zero would be a real regression from 11. Same message, severity now carries meaning. Same defect as the lumped bail counter one layer out: a signal that always says the same thing measures nothing. Test-only. Not built.

docs: T1.d fires in production -- 39% of tiles skipped, measured in game
Classified 1.88 / Meshed 1.15 / SkippedAllAir 0.73 (1.15 + 0.73 = 1.88, exact). Was Classified 1.90 / Meshed 1.90 / nothing skipped. Cave Bail No Layout went 1.58 -> gone. 39% of classified tiles now skipped against 0% this morning, each avoiding ~43000 density evaluations plus marching cubes. First observation of tile-skipping in the running game rather than an automation harness. Not yet firing, stated plainly: TilesSkippedAllSolid and the two op-stack counters remain absent, so the cave branch still produces no verdicts in game -- its attempts land in Cave Bail Mixed Content (0.77) and Stack Verdict (0.32). The win here is the open-air class proved by the classifier's own Z categories, not by ClassifyBox. That is the next thread and the counters now name it.

fix(classify): use the public GetStrateChunkZBounds; the index accessor is protected
VoxelGenerator.cpp(2796): C2248 -- FindSlotIndexForChunkZ is protected. I claimed it was public "verified" in the previous commit. The grep printed the declaration line, not the access specifier above it. Same shape as the partial read that produced a false accusation earlier today. GetStrateChunkZBounds is public (VoxelStrateManager.h:177), returns false for exactly the no-slot case, and ClassifyTile already calls it three times for the same question. Wrapped in a VF_ChunkZHasSlot lambda so the condition reads as the predicate it is. No accessor promoted, no API widened. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(classify): out-of-layout chunks are constant AIR, not TunnelNetwork -- unblocks T1.d
Measured in game: Cave Bail Not Op Stack No Layout = 1.58 of 1.90 classified tiles (83%), with SoleSlot and BoundaryTile never firing. The assets were correctly ticked all along. Cause: GetGeneratorTypeForChunk returns TunnelNetwork for any chunk outside the strate stack, commenting "the fallback density path will produce solid rock anyway". That comment is FALSE. GetGenerationParams for SlotIdx < 0 returns BaseDensity = -1, RoomDensity = 0, WormStrength = 0 -- a CONSTANT AIR field. IsGapChunk's "open air, NOT a gap" was the correct description. So every tile touching the open air above the world looked like a cave archetype, entered the cave branch, found no layout slot, and bailed. T1.d was never failing -- it was unreachable, behind a routing mistake in the archetype lookup that had nothing to do with the operator stack, the box verdicts, or the flags. Fix: ClassifyTile gains a fourth Z category for no-slot chunks. It sets bAnyNonCave (never enters the cave branch) and bCanSolid = false (AllAir survives), and bails to Mixed if a disturbance could add rock there -- chasms only carve, so they cannot threaten an air verdict. A tile entirely above the stack now resolves AllAir and is skipped: the majority of a surface flight, a class T1.d has never been able to prove. Classifier only -- no density value changes. Equivalences must stay bit-identical and violations must stay 0. Not built -- Jahni builds. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs: T1.d blocker FOUND -- out-of-layout chunks misroute into the cave branch
In-game with Sol's four-way split: NotOpStackNoLayout = 1.58 of 1.90 classified
(83%), while SoleSlot, BoundaryTile and MixedContent never fire. So the assets
ARE ticked -- Jahni was right -- and the neighbour theory is dead. The split
earned itself on its first flight; the old lumped counter would have sent us at
the assets again.
Mechanism: GetGeneratorTypeForChunk returns TunnelNetwork for any chunk outside
the strate stack ("fallback produces solid rock anyway"), while IsGapChunk
returns false for above-stack chunks ("open air, NOT a gap"). So every chunk
above TopChunkZ = 0 -- all the open air over the world -- looks to ClassifyTile
like a cave archetype, enters the cave branch, finds no layout slot, and bails.
T1.d was never failing. It was unreachable, behind a routing mistake in the
archetype lookup that has nothing to do with the operator stack, the box
verdicts, or the flags -- all of which are correct and tested.
Not fixed: the two comments disagree about whether out-of-layout is solid rock
or open air, and the right verdict depends on which. Read GetDensityAt's
no-slot path before choosing; guessing there writes a hole.

fix(strate): opt-in diagnostic goes Verbose under automation, not Log
The verbosity fix stopped the diagnostic failing the suite, but it still printed at Log on every Initialize -- which the fixture calls dozens of times per run, burying the actual test output under hundreds of identical lines. Under GIsAutomationTesting it now logs at Verbose (off by default, still available with -LogCmds). Editor and game keep Warning, where it is actionable and fires once per rebuild. The information was worthless in tests anyway: the fixture's opt-in state is known by construction, and the one test that needs the opted-in variant (OpStack.ClassifyTileSoundness) already reports "all 7 cave layout slots have Use Operator Stack enabled" on its own.

docs: suite green after the verbosity fix; FIELD digest proves nothing moved
14/14 pass with no StrateManager warnings. Every reported number is identical to the pre-change run, including the CrossPlatform FIELD digest (0xF62F3D355B1C0BDB) -- a bit-for-bit hash over 115,000 samples of the whole field. That digest is the strongest evidence available: the six-box LRU, the DensityCacheOwnerId key, the bail re-attribution and the scope fix did not move a single voxel between them. Four changes to caching, keying and diagnostics, and the world is byte-for-byte identical -- exactly the contract each claimed, now tested rather than asserted. Still unmeasured: the performance benefit of those caching changes. "Quite a fraction of what it used to be" is a real observation, not a same-seed/ same-route number. Still open: read `Operator-stack opt-in` in the GAME log. That line is the ground truth for T1.d and supersedes both the bail-counter inference and the recorded belief that the assets have the switch on.

fix(strate): opt-in diagnostic must not fail the automation suite
Sol's opt-in warning logs at Warning. UE's automation framework counts a Warning as a failure, and the Determinism.* tests deliberately build a NON-opted-in world -- that world is their comparison oracle, the baseline every OpStack.* number is measured against. The diagnostic was failing the suite by correctly reporting an intentional configuration. Verbosity is now Log under GIsAutomationTesting and Warning otherwise. The message is written once and only the verbosity branches (Printf then log %s): four copies of a long format string across two sites would have been exactly the "one definition, not two kept in sync" failure this project has rules about. CoreGlobals.h included explicitly for GIsAutomationTesting -- IWYU, no shared PCH here. Note for the record: the tests must NOT be switched to the op stack. The non-opted-in fixture is the oracle, not an oversight. The diagnostic also did its job: 7/7 cave slots report disabled in the fixture (slot 4 absent = the SurfaceWorld narrowing working). The same line read from the GAME log is now the ground truth for whether T1.d has ever been enabled in production. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(opstack): hoist the acquired column box out of the integer-XY scope
VoxelDensityOpStack.cpp(832): C2065 'Box' undeclared. The six-box LRU refactor moved acquisition to `FColumnBox& Box = Cache.Acquire(...)` inside `if (bIntegerXY)`, but the Computed flag is set after the column is computed, outside that block. The previous single-box version had Box at function scope so the write-back compiled. Hoists `FColumnBox* AcquiredBox` beside MemoColumn and writes back through it. The guard becomes `if (AcquiredBox)` instead of `if (bIntegerXY)`: non-null implies the integer path, so the pointer proves its own safety rather than relying on two conditions staying in agreement. No caching or logic change. Other Box. uses (761-763) are in scope, verified. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Function-static thread_local CP state previously trusted only chunk coordinates and each manager's locally-reused layout version, allowing a worker to carry params, biome context, CP_UseOpStack, and the built stack into another world.

docs: Sol investigation -- refutes my boundary-tile hypothesis, corrects my false accusation
Sol High investigated with Luna xHigh sub-agents; two approaches built in isolated worktrees, main tree untouched. Two corrections to my own assertions: 1. "One un-ticked neighbouring strate kills boundary tiles" is WRONG. UsesOperatorStackForChunk depends only on ChunkCoord.Z, and ClassifyTile's earlier Z loop already required the predicate for every sampled cave Z within one slot -- so the later XYZ sweep is redundant, not over-strict. Removing it unlocks nothing; boundary tiles still fail the one-slot/type/params guards, correctly. 2. I falsely wrote that VF-03's fixture citation was fabricated. It exists (VoxelForgeTestFixture.h ~134/146, explicit about CP_UseOpStack contamination). I had read only the 30-line header and asserted a negative from a partial read. Header corrected. VF-03's core claim is now CONFIRMED: GetDensityAt keys thread_local CP_* by (ChunkCoord, LayoutVersion) with no world identity, and every manager's version starts equal. Also: the Cave Bail Not Op Stack counter I specced is ambiguous -- it fires before the different-slot attribution, so it cannot distinguish "flown slot un-ticked" from "boundary tile met an un-ticked slot first". My 80% reading was over-confident. Same defect I fixed for TilesSkippedAllSolid, reintroduced one layer down. Approach A recommended (explicit opt-in + six-box LRU) over B (code-enforced cutover): the code does not justify weakening ClassifyTile, and B would delete the flag, which is the only same-route A/B lever available to prove the refactor. Narrow A's warning to cave archetypes before adopting. Nothing built. Worktrees left in place for review. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs: T1.d is blocked by CONFIG not code (Cave Bail Not Op Stack = 80%); retract memo claim
Part B paid for itself on its first flight. Over the caves, Tiles Classified == Tiles Meshed (nothing skipped at all) and CaveBailNotOpStack accounts for ~80% of cave-branch attempts. That counter has exactly one cause: UsesOperatorStackForChunk returned false -- so either the strate flown over has not ticked bUseOperatorStack, or a chunk in the tile's box belongs to an adjacent strate that has not, since the per-chunk sweep requires every chunk to agree. CaveBailStackVerdict being non-zero (0.32) corroborates: where the flag did hold for the whole box, the stack built fine and merely returned Mixed. The machinery works; it is mostly not being reached. RETRACTION: I called the column-memo port a regression after comparing 14.7% from one flight against 23.3% from another. Invalid -- the miss rate is strongly location-dependent (~10-30%) and was in that band before the port. Comparing single-flight averages from different routes measures the route. A real before/after needs the same seed and route; parked until then, and not urgent. Kept while diagnosing: GSurfColCache is a 6-box LRU, not one box. My spec said "a direct-indexed box" and Codex implemented one faithfully, so any recentre now wipes all 6561 cells where the old table lost one entry. Plausible thrash source, unmeasured. Port the LRU if the memo is revisited. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(world): drain workers before mutating strate layout/passages (VF-01)
Initialize does StrateLayout.Empty() and Passages.Empty()/Add() -- freeing and
reallocating both -- with no guard, while mesher workers read them through
AnyPassageNearBox, EvaluateModifierSDF and FindSlotIndexForChunkZ. The epoch is
bumped AFTER, so previous-epoch workers are live during the mutation; the epoch
rejects a finished result, it cannot make a read of a freed allocation safe.
Same class as the DiffLayer.ChunkMods carve-vs-stream AV that ModsLock fixed.
Chose the drain over the two alternatives:
- FRWLock on the arrays: correct, exact in-repo precedent, but a read lock on
the per-voxel hot path (~43k/tile) would contaminate the perf measurement
CODEX-TASK-001/002 are queued to take. Worst possible timing.
- Immutable generation snapshot (Sol's proposal): right long-term, refactors
the whole StrateManager API surface. A design conversation, not an agent's
unprompted call.
- Drain: zero hot-path cost, reuses the machinery EndPlay already proved, and
its stall lands only on human-initiated editor actions, never during play.
FScopedGenerationPause raises a new bGenerationPaused (deliberately NOT
bShuttingDown, which means teardown) and drains both reader populations: chunk
tasks via ActiveTaskCount and decoration tasks via a new
WaitForDecorationTasks, whose refactor also removed NotifyShutdown's duplicate
spin loop. On timeout it does NOT mutate -- logs an Error and leaves the world
consistent. A timeout that proceeds is what the bug already does.
RebuildStrates, OnObjectModifiedInEditor and ChangeSeed cannot reach Initialize
without the pause. BeginPlay untouched (no tasks yet). EndPlay untouched --
VF-02's 3s timeout is a separate deliberate decision.
Verified: four files, no density/mesher file, so terrain cannot move.
ShouldAbortWork replaced three existing checks, adding none. No worker path
waits on the game thread, so the drain is bounded.

docs: VF-01 confirmed (worker race on rebuild) + VF-10 triaged; hold further code
VF-01 CONFIRMED and it is the most serious find of the day. Initialize does StrateLayout.Empty() and Passages.Empty()/Add() -- freeing and reallocating both -- with no lock, barrier or drain anywhere in that file, while worker threads read the same arrays through AnyPassageNearBox (:460), EvaluateModifierSDF and FindSlotIndexForChunkZ, reached from GetDensityAt/ClassifyTile. RegenerateAllChunks bumps the epoch AFTER the mutation, so previous-epoch workers are live during it; the epoch rejects a finished result, it cannot make a read of a freed allocation safe. Same class already fixed once here: DiffLayer.ChunkMods got ModsLock after a carve-vs-stream AV. The dangerous call site is OnObjectModifiedInEditor, which fires automatically on a strate asset edit while streaming -- routine here. VF-10 confirmed real (74 fields, per near-surface sample) but Sol missed the conclusion: the copy is INHERITED from GetDensityWithParams, so both paths pay it and it does NOT explain the op-stack regression. The op stack improved it by memoising across eleven detail ops. Future optimisation, not the answer. Deliberately NOT fixing VF-01 now. Four code changes are stacked unbuilt and three have "nothing should move" as their acceptance signal; a fifth change to streaming lifecycle would make an odd build result unattributable. The three fix options (drain / snapshot / RWLock) trade a possible crash for an editor hitch or hot-path lock traffic -- a product decision, not an agent's.

fix(morphology): BuildChunkCache under-bounds room/tunnel collection when Min > Max
Third instance of the same class, and the worst one -- found by the Sol-High
read-only audit (VF-05) and verified against the code before acting.
MaxInfluence, RoomZBuffer and EvaluateSDF's Margin all derive from
MaxRoomRadius / TunnelMaxRadius, while the radii are Lerp(Min, Max, hash), which
yields up to max(Min, Max). A room able to reach a chunk can therefore sit in a
cell the collect region never visited.
Worse than the two fixed earlier today because:
- it is TunnelNetwork, the largest archetype;
- BuildChunkCache is called by BOTH density paths (FRoomGraphSource calls it
rather than transcribing it), so this was never an op-stack bug -- it is in
the shipped original code and always has been;
- the failure mode is a window-invariance break (ARCHITECTURE 8.4): whether a
room exists depends on which chunk you queried from, which in multiplayer
means two peers generate different geometry from the same seed.
Four bound sites now use RoomRadiusEnvelope / TunnelRadiusEnvelope; the two
duplicated copies of the formula still compute the identical expression. No
Lerp, placement, hash or bStore line changed -- with correctly ordered params
max(Min,Max) == Max, so this is bit-identical. A no-op at correct values is the
acceptance signal.
Also adds a reviewer's header to AUDIT-2026-08-CODEX.md marking which findings I
verified (VF-05 confirmed, VF-02 premise confirmed, VF-03 evidence overstated --
its cited fixture corroboration does not exist) and which are unverified leads.

docs(opstack): two comments still described a half-finished port that is finished
Both said the refactor was mid-flight and both contradicted the code around them. 1. BuildTunnelNetworkStack: "stage A of three, the twelve detail modifiers and the per-room override are not ported yet, which is why UsesOperatorStackForChunk returns false for TunnelNetwork." All three stages are done, the twelve modifiers are added a dozen lines below the comment, and that function returns true. 2. FIslandBlobSource: "two of the three frame users are not ported yet; revisit when TunnelNetwork brings the second real use." TunnelNetwork is ported, and BuildTunnelNetworkStack already records the verdict: CaveWarp wraps exactly one operator and VerticalScale is a pure scalar function, so ZERO frames out of three candidates. The question was answered; only this comment still asked it, and it would have sent the next reader off to build frame infrastructure that was explicitly decided against. A comment that contradicts the code beneath it is the "read the code, not the comment" trap in reverse. This file already carries the forward version of that lesson, at the cliff modifier whose comment promises a gradient it never samples. Comments only -- no code changed.

The "a sampler must cover at least one period" bug was found in the tunnel test (+/-32 vs RoomSpacing 80) and again in the shaft test (+/-48 vs ShaftSpacing 55). Both were fixed. The class was not: three box-verdict scans still ran the original RandRange(-6,6)*Extent at Step 1 / Cells 8, i.e. +/-48 voxels.

fix(opstack): two cell-sweep pads assumed MinRadius <= MaxRadius; a third already didn't
Second defect from the full 28-op EffectOverBox audit. Three ops roll a radius as Lerp(MinRadius, MaxRadius, hash01), which lands in [min(A,B), max(A,B)] -- Lerp does not require A <= B. Their EffectOverBox sweeps lattice cells padded by the largest radius a cell could hold, so a pad below the true maximum means the cells are never examined and the op reports Identity for a box its own Eval will fill or carve: no geometry, no collision. FGridColumnMod ~1086 Max(MaxRadius, 0) exposed FShaftFieldSource ~1436 Max(ShaftMaxRadius, ConnectorRadius) exposed FIslandBlobSource ~1803 Max(IslandMinRadius, IslandMaxRadius) already correct The third one is the argument: the concern was met and guarded once in this same file, and the other two shipped without it. Fixed with FMath::Max3, a spelling already used here (~2481) and in VoxelCaveMorphology.cpp. Shipped defaults are ordered correctly (2/5, 2/7, 5/11), so this is a NO-OP at defaults -- that is its acceptance signal, and any moved number means the diff did more than intended. It needs a mis-ordered asset value, which nothing prevents: ClampMin is a per-property floor and UE cannot express "<= that other property". ColumnMinRadius is also settable per-room via UVoxelTerrainOpDefinition. Deliberately NOT fixed by normalising the params: swapping the Lerp endpoints maps the same hash to a different radius, changing geometry and breaking the eight equivalence tests. Only the bound becomes conservative; Eval is byte- identical -- verified, no Eval/Roll/GetCells line in the diff. Also audited and found sound (recorded so they are not re-chased): FPassageCarveOp and the passage bounding sphere, FOriginSpineOp, FBoundarySealOp, FShaftLedgeMod, FCaveArchMod, FDomeMod.

fix(opstack): three ExtraReach box verdicts used sup|FBM| = 1.0; the proved bound is 1.5
CORRECTNESS on a box verdict, not perf. This file derives |Perlin3D| <= 1.5
rigorously, exposes it as PerlinAbsBound, uses it for the tunnel warp, and says
outright that the header's "~[-1,1]" is an observation and that a box verdict
resting on one is a hole. Three ExtraReach formulas in the same file assumed
sup|FBM| <= 1.0 -- and VoxelNoise::FBM normalises (Total / MaxValue), so
sup|FBM| = sup|Perlin3D| exactly. The bound was wrong by 1.5x.
At shipped defaults, soundness needed B <= 1.27 (VerticalShafts, Rough 3.0) and
B <= 1.40 (Maze, Rough 2.0); both are violated at B = 1.5. Break-even roughness
is 1.6. FloatingIslands survives only because its SDFBlendRadius is 5 -- sound
by parameter luck, not construction.
Nothing in the running game was affected (no strate has bUseOperatorStack
ticked) and the empirical Perlin sup ~1.0-1.1 is why nothing surfaced. But the
tile scans SAMPLE, and for shafts they sampled a source that proved zero tiles

docs: close C2, sharpen the column-memo prediction, reassess REVIEW_FINDINGS
Reading session -- no build available, so: verify things instead of writing code. - Cross-checked the eight stat declarations against their definitions and use sites. Identical. The one compile risk I had only eyeballed is now retired. - REVIEW_FINDINGS: the GetDensityWithParams and BuildChunkCache splits are now counter-productive rather than optional -- the op stack is replacing the first, and FRoomGraphSource deliberately CALLS the second so a restructure forks what was kept unforked. The two passage enums are not duplicates and are UMETA-serialised into authored assets; merging them rewrites content for tidiness. Judged: leave, and close the item. - CODEX-TASK-002's acceptance said "20-30% of lookups", a guess wearing a number. Replaced with arithmetic from the real grid: 1225 columns/tile over 35 Z planes, load factor 0.299, ~317 colliding columns, ~12000 vs 1225 computations = ~9.8x. Plus the reading rule that matters -- the overhang and cliff mods re-query the same XY and add HITS only, so compare the ratio of the two hypotheses, not an absolute percentage.

docs(audit): C2 is FULLY closed -- the live-edit half was fixed too
Was about to spec a Codex fix for OC_Chunk / BM_Chunk / FChunkBiomeCache, which three docs still list as open. Checked the sites first. All of them already carry a layout-version guard: CP_Chunk -> CP_Version OC_Chunk -> OC_Version BM_Chunk -> BM_Version TC_BiomeCache -> TC_SeenVersion FChunkBiomeCache::Invalidate() exists precisely because the validity box says nothing about the FBiomeContext its cells were classified against, and all four thread_local instances call it on a version change. The only other two instances in the tree (VoxelContentManager ~445, the height-stack test) are function-local, constructed per task, so staleness is impossible there. Seventh time in this project a confident premise reversed on reading. It cost a doc edit instead of a Codex run and a build cycle. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

feat(stats): stat VoxelForge -- make tile skipping and the column memo observable
The plugin had ZERO stat counters, so every claim this refactor makes was harness-only: "skipped correctly" and "skipped nothing" render identically. CODEX-TASK-001 and -002, executed by Codex (gpt-5.6-luna xhigh), reviewed against the source. Eight DWORD counters in a new stat group: GenerateTileResult -- TilesClassified / SkippedAllSolid / SkippedAllAir / Meshed ClassifyTile bAnyCave exit -- TilesOpStackSolid / TilesOpStackAir FSurfaceColumnSource::GetColumn -- ColumnMemoHit / ColumnMemoMiss The op-stack counters are separate from the lumped skip counters on purpose: ClassifyTile also proves AllSolid on its hand-written bedrock-gap path with no strate opted in, so the lumped number cannot show a before/after. The op-stack pair is zero BY CONSTRUCTION until a strate ticks the flag. GetColumn is instrumented and deliberately NOT fixed -- the instrument and the fix in one build would make each other unreadable. Verified against UE_5.7 Stats.h rather than assumed (first stats use in this plugin, no in-repo precedent): all four macro arities, and INC_DWORD_STAT -> FThreadStats::AddMessage, so the worker-thread safety both sites need holds by mechanism. Not built -- Jahni builds. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs: spec CODEX-TASK-002 (column-memo thrash) and aim the PERF work
Three orchestration findings on the parked PERF item, none measured yet: 1. The perf A/B needs no new code -- two Insights traces on a deterministic world are a clean before/after. But tile skipping changes how many times GenerateMesh runs, so totals conflate "cheaper per tile" with "fewer tiles". TilesMeshed from task 001 is the denominator. 001 is therefore a PREREQUISITE for the perf work, not a parallel item as the handoff had it. 2. The suspects don't share an archetype: SurfaceWorld is the column memo, TunnelNetwork is 19 virtual calls per voxel (16 + 3 structural post). One lumped number can't be acted on -- measure one strate at a time. 3. GetColumn is a direct-mapped hashed table where GSurfColCache is a direct-indexed box, and the mesher pre-samples Z-OUTERMOST (verified, VoxelMarchingCubesMesher.cpp ~226) so every column is revisited ~34x per tile. The table's sizing comment reasons about fullness; a direct-mapped table evicts on collision. At load factor 0.28 that is still ~25% of columns recomputing the full height stack every Z plane -- derived ~9x. Task 002 measures that and fixes nothing, so the instrument and the fix cannot land in the same build and make each other unreadable. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs(codex-001): the lumped AllSolid counter cannot prove T1.d -- add the op-stack site
Reviewing the spec against ClassifyTile reversed its acceptance bar. The function reaches a non-Mixed verdict two independent ways: the hand-written path (a bedrock gap sets bCanAir=false, VoxelGenerator.cpp ~2835, and the tile resolves AllSolid) and the operator-stack path (the bAnyCave block). The first fires with NO strate opted in, so the spec's baseline -- "TilesSkippedAllSolid stays 0 underground" -- was never going to hold, and the before/after would have been unreadable. Adds site B at the bAnyCave exit (~3009) with TilesOpStackSolid / TilesOpStackAir. Those are zero BY CONSTRUCTION without an opted-in strate, since the branch returns Mixed at the UsesOperatorStackForChunk gate -- a stronger baseline than the one it replaces. Deliverable is now: tick the box, TilesOpStackSolid goes non-zero. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs: spec CODEX-TASK-001 (tile-skip stats) and refresh the handoff for the Codex tandem
Jahni built a world and said "I don't know if it dropped any meshing? but it
looks alright by the eye." That sentence is the honest state of this refactor:
everything proved so far was proved in an automation harness on 40 sampled
tiles, and in the running game tile-skipping is unobservable.
grep INC_DWORD_STAT over Source/ returns nothing -- the plugin has zero stat
counters -- and "skipped correctly" renders identically to "skipped nothing", so
no visual check can separate them. The tests got the "coverage is a number, not
a boolean" discipline this session; the game never did.
CODEX-TASK-001-tile-skip-stats.md specs a stat VoxelForge group with
TilesClassified / TilesSkippedAllSolid / TilesSkippedAllAir / TilesMeshed. Solid
and air are split deliberately: cave archetypes prove AllSolid, so that counter
is the one that says whether the op-stack work did anything real. Its deliverable
is the before/after that constitutes the PRODUCTION proof of T1.d, which does not
exist today.
The spec carries the invariants rather than just the task, which is the point of
a spec here: bTrivialEmpty decides whether a tile has COLLISION, the five-clause
gate is load-bearing, and GenerateTileResult runs on worker threads -- so a plain
static int32++ is a data race while INC_DWORD_STAT is not.
Handoff updated: a "How we work now" section (Codex Model Luna xHigh writes most
code, Claude orchestrates -- hand over the INVARIANT, review against the code and
not the description), first actions split into the Codex task and the pending

docs(opstack): experimental is pushed and tracked -- correct the flat "never push" rule
The rule said "Never push" without qualification, which was true while experimental existed only locally and became misleading the moment it did not: a future session would read it and let origin/experimental drift. Now: push experimental freely (tracked since 2026-07-29), never push main, which stays pinned at the known-good commit. Both statements of the rule are updated (OPSTACK-HANDOFF.md and OPSTACK-PROMPT.md's crash-safe discipline). Also added at both sites, because it is the failure mode this creates: a pushed commit is NOT a "verified green" marker. This branch carries unbuilt work by design, so OPSTACK-PROGRESS.md remains the only record of what was actually built and measured, and the remote records only what was written.

docs(opstack): rewrite the handoff for the T1.d-delivered state
The old handoff's "first action" (confirm the Underwater coverage number) and its
"one task everything is waiting on" (make FRoomGraphSource::EffectOverBox answer
spatially) are both done, so most of it was actively misleading.
What it says now:
- T1.d is real and measured: 11 of 40 tiles proved AllSolid at production
defaults, 14641 voxels brute-forced, 0 violations; dense fixture correctly 0.
- A boxed invariant near the top, because it is the most dangerous thing in the
current code: Identity from the room source means Sdf >= T, not FLT_MAX, and
any new Sdf consumer with a bigger threshold silently produces tiles with no
geometry and no collision.
- First action is now "build

feat(opstack): VerticalShafts' connector branch never tested a connector -- test the real capsules
Jahni's call: bank T1.d at 11/40 and take VerticalShafts rather than squeeze the Perlin sup. Right call -- a clearly-scoped defect with no hole-risk maths, on an archetype that was getting nothing. The defect is stated in its own comment. FShaftFieldSource::EffectOverBox ended with a "connectors" branch that never looks at a connector: it returns CarveOnly because a shaft EXISTS within Spacing*1.6 + Pad. At ShaftSpacing 55 and ShaftDensity 0.6 that box spans ~4x4 cells and ~10 shafts, so the condition is true essentially everywhere -- exactly the reported 0 proved of 60. Conservative, never wrong, completely sterile; the same shape as the worm's unconditional CarveOnly one archetype over. It now rebuilds the connectors the way GetCells does and tests the real capsule. Two things had to be right and both were read in the source rather than assumed: - The enumeration is a superset. Eval reads connectors from the 3x3 of ITS query's cell, so any pair visible from a point in the box has both shafts in the 3x3 of some cell the box touches, i.e. in [box cells] +- 1 -- the range swept here. Pairs no query ever sees may be produced: extra CarveOnly, never a hole. - The pair order matches, so the hash matches. VoxelHash::Pair is fed in insertion order and GetCells inserts over (dy, dx), row-major; this sweeps (cy, cx), and row-major order restricted to a sub-grid preserves the relative order of two cells. So the same pair gets the same hash WITHOUT assuming Pair() is symmetric -- which was never verified and now need not be. The capsule test splits the axes because a connector is HORIZONTAL at height Zc: Z is exact, XY is point-to-segment from the box centre minus the XY half diagonal. Tighter than the 3-D half-diagonal the tunnel version had to settle for. Also the same sampler trap, caught before the build this time: tile XY was drawn from +-48 voxels against ShaftSpacing 55 -- under one period of the pattern, identical in kind to the +-32-vs-80 bug that cost the tunnel test three runs. Widened to +-440, and the report prints its own extent in units of ShaftSpacing. The safety net was already there and is untouched: this test brute-forces the full lattice of every proved tile, both hypotheses, and AddErrors on the first violation. If the superset or hash-order argument is wrong, the assertion fails rather than a player falling through the floor. Unbuilt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

docs(opstack): WARP SHARE measured -- half the blocking is the box; plus two corrections
The instrument landed on its first run. At production defaults, rooms reaching go 0.9 -> 0.4 and tunnels 2.4 -> 1.1 when the warp dilation is set to zero: more than half of all remaining blocking is the query box rather than cave geometry. Hypothesis confirmed, and the number is permanent output now. CORRECTION 1. Last entry I claimed BuildChunkCache's Expansion = CaveWarpStrength + 2 means "the whole plugin bets on |Perlin3D| <= 0.8", and used it to argue 2.0 was needlessly conservative. False. Six lines further down, bNeedRebuild tests WarpedX < CachedSMinX || WarpedX > CachedSMaxX -- the cache REBUILDS when the warped query leaves the box, so that expansion is a rebuild-frequency heuristic and nothing bets on 0.8. The 2.0 -> 1.5 change stands on its own derivation. Sixth premise this refactor that reversed on checking, and I asserted this one in the same entry where I diagnosed the habit. CORRECTION 2 / NEGATIVE RESULT. The obvious next move -- evaluate the warp at the box centre, SHIFT the box, dilate only by the variation across it -- does not pay here, worked out before writing it. A rigorous per-axis Lipschitz bound for this Perlin3D is |dV/dfx| <= 4*1.875 + 1 = 8.5 per unit cell (fade derivative times the spread of GradDot, plus GradDot's own linear term, u and v being distinct axes). The half-box is 0.206 in noise units, so the local variation bound is 1.75 against a GLOBAL range bound of 1.5. The local bound is worse than the global one. Recorded so nobody spends a build rediscovering it. That leaves one route for the warp term: tightening the sup of |Perlin3D| from the proved 1.5 toward its apparent true value ~1.0-1.1, worth ~27% of the dilation. Spot-checking a grid is not a proof, and a sup proved wrong is a tile with no geometry and no collision -- so that is a judgement call about appetite, not a technical unknown. State: T1.d delivered and verified. 11 of 40 tiles (27.5%) proved AllSolid at production defaults, 14641 voxels brute-forced, 0 violations. The dense fixture correctly proves nothing.

fix(opstack): the warp bound was the dominant term all along -- 2.0 -> 1.5, and MEASURE it
Jahni asked whether I was in a loop. I was, and re-reading the original found it
in one line.
PerlinAbsBound was set to 2.0 in the first commit of the spatial EffectOverBox
and never revisited. The dilation is CaveWarpStrength * VOXEL_NOISE_SCALE *
PerlinAbsBound, and CaveWarpStrength is 8.0 by default:
8 * 1.25 * 2.0 = 20 voxels, applied +/- on every axis
tile 10 voxels -> query box 50 per side -> 125x the tile volume
So the tunnel test I called "an order of magnitude tighter" actually needed
DistToAxis >= 78 against a cull rejecting at ~107. 27% tighter, not 10x -- and
the run said so: tunnels reaching went 78.0 -> 58.5, a 25% cut. The instrument
was right and I credited the tunnels.
Four rounds -- worm, columns, sampler, tunnel disjunction -- each individually
correct, every one of them tightening around a term nobody had measured. I kept
instrumenting what I had just changed and never instrumented what I had assumed.
What re-reading showed: BuildChunkCache is called everywhere with
Expansion = CaveWarpStrength + 2.0f, which is only correct if |Perlin3D| <= 0.8.
The whole plugin has always bet on 0.8. I picked 2.0 -- 2.5x more conservative
than the assumption the cache's own correctness already rests on.
The corrected bound is derived, not guessed. GradDot returns +-u +-v with u and
v two DISTINCT components (checked on all four hash branches). Splitting the
eight corners by i gives, per axis, sum w*|dx| = (1-su)*fx + su*(1-fx) <= 0.5
(max at fx = 0.5). Hence |Perlin3D| <= S_x + S_y + S_z <= 1.5, with no case
analysis on the hashes. Dilation 20 -> 15.
And the instrument that should have existed from the start: EffectOverBox now
also runs every room/tunnel test with the warp dilation set to ZERO and reports
both, so Hit* - Hit*NoWarp is exactly the blocking caused by my box rather than
by geometry. The report says, in the output, that if that gap dominates the next
move is the warp bound and not the primitives.
Separately: the diagnostics had turned into narrative, printing hardcoded numbers
from previous runs next to live ones ("32 of 34 tiles vs 21 for rooms" while the
live figures said 21 of 28). Unreadable, and I wrote all of it. Diagnostics now
report THIS run; the history stays in OPSTACK-PROGRESS.

feat(opstack): tunnels get a threshold test -- T1.d is measured at 6 of 40 tiles, 0 violations
THE PRIZE LANDED. At production defaults: 6 of 40 tiles proved AllSolid, 7986 voxels brute-forced, 0 violations. 15% of tiles skip GenerateMesh entirely, one BuildChunkCache traded against 30000+ density evaluations each, and not one verdict is asserted -- every voxel was re-evaluated and came back on the claimed side. The dense fixture still reports 0, exactly as the arithmetic said it must, so this is a measurement of production rather than of a widened test. The breakdown finally isolated the tunnels: of 34 unproved tiles, 32 were blocked by a tunnel and 21 by a room, so >=13 were tunnel-only. That is what justified the deferred disjunction, and why it was deferred rather than guessed. A primitive no longer matters if it misses its cull OR its own SDF stays >= T+K over the box. Each branch wins on a different class, by calculation: for rooms the cull (Rmax+3K) is tighter than the threshold (Rmax+T+K), so rooms keep the cull alone; for tunnels the cull is a capsule BOUNDING SPHERE, radius ~107 for a 200-long tube of radius 7, against a true segment distance. Order of magnitude. The bound is exact, not cautious. TaperedCapsule was read, not assumed -- Dist(P, ClosestOnSegment) - Lerp(Ra,Rb,t) -- so SDF >= dist(P,segment) - max(Ra,Rb); and dist(box,segment) >= dist(centre,segment) - half-diagonal by triangle inequality. VF_DistPointSegment is written locally rather than taken from FMath: five lines, and "I think that function does that" is not good enough under a correctness bound. Identity CHANGED MEANING, from "Sdf stays FLT_MAX" to "Sdf >= T" with T = max(3*SDFBlendRadius, WormNetworkRange). Sound only because all three consumers of the SDF channel were read one by one: FSdfConvertOp's Blend is MakeSdfCarve(P.SDFBlendRadius, ...) => K; the twelve modifiers gate at 3K; FWormFieldSource at WormNetworkRange. Plus the one that could have bitten -- FCaveTerraceMod re-probes the SDF at Z+-1, OUTSIDE the box, but its gate is line 13 and the probes are lines 28-29, so a gate false everywhere never emits one. ANY NEW CONSUMER OF THE Sdf CHANNEL MUST HAVE A THRESHOLD <= T OR JOIN THAT MAX, or it gets tiles with no geometry and no collision. Written at the site. Why -K suffices for any N: SmoothMin's penalty is exactly zero once |A-B| >= K, so the running minimum saturates at K below the smallest term and cannot descend further. Sdf >= min_i(SDF_i) - K for ANY number of primitives, not - N*K/6 -- without which the slack would scale with the ~88 tunnels and be worthless. Unbuilt.

test(opstack): measure the box verdict on BOTH densities -- the fixture cannot prove a tile
The widened sampler worked: 39 of 40 tiles now land clear of the (0,0) spine.
The verdict did not move -- rooms still hit 40 of 40. By my own pre-registered
rule that means the room-lattice model was wrong, and it was, for a reason the
report had been printing at me for three runs: "= 7.6 x RoomSpacing 42".
RoomSpacing is 42 here, not the 80 I did the arithmetic with. I read the
UPROPERTY default out of the header instead of the fixture that overrides it.
Fifth premise this refactor that reversed on being checked, and the plainest:
the number was on screen.
EnableTunnelFeatures densifies on purpose -- RoomSpacing 80 -> 42, RoomDensity
0.35 -> 0.85 -- because at the defaults only 1.1% of samples were in open cave
and the equivalence compared solid rock to solid rock. That densification is what
makes check 1 mean anything, and it is exactly antagonistic to provability:
room cull radius = max(R*1.5, R*HeightRatio) + 3*SDFBlendRadius
= 1.5R + 12 for R in [10,30] => 27..57, mean ~42
lattice spacing = 42 at 85% occupancy
The mean cull radius equals the lattice spacing, so cull spheres cover that world
~3.6x over and NO box can be outside all of them. "6.3 of 8.3 rooms reach" is not
a loose test, it is a saturated world. No sampler change and no tunnel tightening
can move it -- which is why widening the sampler correctly changed nothing.
So 0 proved on this fixture is the RIGHT answer, and informative: the prize
shrinks to nothing as caves saturate. It is simply not an answer about
production.
Check 4 is now a lambda run twice -- parameterised rather than copy-pasted,
because two copies of the criterion would drift and the second would lie:
[dense fixture] as before, expected to stay ~0 and now documented as correct;
[production defaults] the same 40 tiles against RoomSpacing 80 / RoomDensity
0.35, the real UVoxelStrateDefinition defaults. Both brute-forced voxel by voxel.
Not "widen it until it passes": the dense run stays in the report, must stay ~0,
and a false verdict in either still fails. The two stacks deliberately share
FRoomGraphSource's thread_local caches, so this run and check 3 now watch each
other through the params fingerprint in the key.

test(opstack): the tile sampler never left the (0,0) spine -- widen it to 4x RoomSpacing
The per-class breakdown refuted my own hypothesis on its first run. I predicted "tunnels >> rooms, so it is capsule bounding spheres". Tunnels ARE wildly over-counted (69.2 of 80.4 reach), but rooms hit all 40 tiles too, so fixing tunnels alone would have moved the number by exactly zero. Fourth confident chain this refactor that reversed on contact with a measurement. The real finding is that the measurement was invalid. The sampler drew tile XY from RandRange(-4,4)*8, i.e. +/-32 voxels, against RoomSpacing = 80 and a guaranteed OriginRoomRadius = 20 room at (0,0) whose cull radius is 42, with the (0,0) spine descending exactly there. All 40 tiles sat inside the origin room's cull sphere, in the most cave-riddled spot in the world. "4.9 of 7.2 rooms reach" was measuring the spine hub, not the world's cave density -- every conclusion about whether deep rock is provable was answering another question. Widened to +/-320 voxels (4x RoomSpacing). The report now prints its own sampling extent and how many tiles landed clear of the spine, because a sampler whose extent you cannot quote is one nobody is watching. This changes what the measurement LOOKS AT, never what it demands: every verdict is still brute-forced voxel by voxel, so a wider sampler that produced a false verdict still fails. Also worked out, before writing any code, why rooms cannot be tightened and tunnels can. SmoothMin's penalty is exactly zero once |A-B| >= K, so the running minimum saturates at K below the true minimum and Sdf >= min_i(SDF_i) - K for ANY number of primitives. With K=4, WormNetworkRange=24, mods gating at 3K=12, the threshold T is 24. For rooms the cull rejects at Rmax+3K=57 while an "Sdf >= T+K" test rejects only at Rmax+T+K=73 -- the cull is strictly better. For tunnels the cull is a capsule BOUNDING SPHERE, radius up to ~107 for a 200-long tube of radius 7, while the real segment distance rejects at 35. An order of magnitude, and sound because TaperedCapsule is a genuine distance function (verified, not assumed). That disjunction is NOT in this build on purpose: it changes what Identity means here, from "Sdf stays FLT_MAX" to "Sdf >= T", which is only sound if every consumer threshold is <= T. Three premises still need reading rather than assuming -- VF_NearCaveSurface's constant, the Blend passed to FSdfConvertOp, and whether any modifier re-probes the SDF outside the box before its gate. Fix the measurement first; it costs nothing and it is wrong today. Unbuilt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

perf(opstack): drop the redundant column test, and measure WHICH primitive class blocks the box
The worm fix worked -- attribution now reads "AllSolid killed by: RoomGraphSource x40", with WormFieldSource gone from the list. The blocker moved one operator upstream. And my own warning is now the thing to distrust. It said "if it names RoomGraphSource, the tiles genuinely straddle cave", which is a hypothesis wearing the costume of a conclusion -- the same mistake as the previous warning, one level down. RoomGraphSource has four primitive classes behind it whose bounds differ enormously in quality. No third guess. PROVED, not guessed: the columns test is removed. It treated columns as infinite cylinders in Z (the cache gives them no vertical bound), so a box hundreds of voxels below the owning room answered Both over a shared XY circle. It was REDUNDANT rather than conservative: columns are read by exactly one operator, FRoomColumnMod, whose Eval opens with VF_NearCaveSurface(InOut.Sdf, ...). In a box no room/tunnel/pit/chimney reaches, Sdf stays FLT_MAX everywhere, so no column can execute wherever it sits in XY. Removing it tightens the verdict without touching correctness. THE INSTRUMENT: EffectOverBox no longer early-outs on the first hit, it counts all four classes -- stopping at the first gives the right verdict and no information, which is exactly why "RoomGraphSource x40" was unactionable. Free at the scale that matters: BuildChunkCache has just run and dwarfs a walk over ~100 structs, and the verdict is memoised so the walk happens once per box. GetLastRoomBoxDiagnostic reads back what the operator computed rather than letting the test re-derive the criterion. The test could replay it -- and that second definition would drift from the real one and lie on the day it was believed. Same reason VF_BuildOpStackForChunk exists. The hypothesis it exists to kill or confirm: a tunnel is culled per voxel by its BOUNDING SPHERE, an enormous over-estimate for a long thin capsule, while a room's cull sphere is a fair fit. Tunnels >> rooms would mean the box test is losing to capsule bounding spheres rather than to real cave. NOT done deliberately: tightening tunnels to a true capsule test is not free correctness -- the per-voxel cull IS the bounding sphere, so a capsule test would be tighter than the cull and would break the stated criterion. Making it sound needs "no primitive can bring Sdf below max(Blend, SDFBlendRadius*3, WormNetworkRange)", which needs a bound on how far SmoothMin of N primitives dips below min. Real 0.2 design work, and doing it blind before knowing whether tunnels are even the problem is the C10 mistake verbatim. Unbuilt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

fix(opstack): the worm inherits the room source's box verdict -- the actual blocker
First build of the spatial EffectOverBox came back green with 0 tiles proved of 40. The warning written for exactly that case fired, and then was not good enough: it offered two candidate causes and BOTH were wrong. The real one was a third operator neither candidate mentioned. FWormFieldSource answered CarveOnly unconditionally with a provably correct amplitude bound of WormStrength. But BaseDensity = 8 and WormStrength = 10 are the DEFAULTS -- the field's own comment requires the worm to exceed BaseDensity or it could never carve air. So SolidMargin = 8 - 10 < 0 on every tile of every strate with worms on, before the fold reached anything the room source proved. A numerically correct bound that is structurally always fatal. The fix was already written three lines up in the worm's own Eval: NetworkMask is 0 when CaveSDF >= WormNetworkRange, which FLT_MAX always satisfies. The worm IS spatially bounded -- by the room source's bound, exactly like the twelve detail modifiers -- so where the source proves Identity it does not execute at all. Thirteen inheritors instead of twelve. Verified FVoxelOpSample::Sdf really does initialise to FLT_MAX rather than assuming it; the inheritance inverts into a hole otherwise. Deliberately NOT VF_NoCaveOverBox: that helper answers "identity" for a null Rooms, correct for the twelve modifiers and wrong for an op a future assembly could place behind a different SDF writer. No room source means we do not know, which must cost CPU rather than a hole. And the instrument, because the guess is the thing that cost a build: a diagnostic that lists candidate causes without measuring them is still a guess wearing rigour. FVoxelOpStack::ClassifyBoxAttributed reports the index of the first op that kills each hypothesis -- same loop, same early-out, verdict identical to ClassifyBox, because a diagnostic that takes a different path than the thing it explains sends you hunting in the wrong place. IVoxelDensityOp::DebugName gives them names and touches no cache key, so it cannot change the world. Check 4 now always prints "AllSolid killed by: <op> xN", and the zero-proved warning says to read it instead of re-deriving. Unbuilt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

feat(opstack): FRoomGraphSource::EffectOverBox answers spatially -- and AUDIT C2 is fixed
The chain no longer dies at the room source. The criterion is the per-voxel cull
lifted from point to box, which can fail for exactly one reason: Eval starts at
MinSDF = FLT_MAX and only lowers it through a primitive that survives its own
cull, so if no cached primitive survives its cull anywhere in the box, Sdf stays
FLT_MAX across the whole box.
FSdfConvertOp already returned Identity ("la source a repondu pour la paire") and
the twelve detail modifiers already inherited through VF_NoCaveOverBox. One
function learned to answer and fourteen operators became provable -- what the C1
wiring was built for.
Three deliberate choices, all erring toward CPU rather than toward a hole:
- |Perlin3D| <= 2, derived from GradDot + the convex hull of a trilinear lerp,
instead of the header's observed "~[-1,1]". A verdict resting on an observation
is the hole this file spends its life avoiding.
- the op pool is passed to BuildChunkCache, not nullptr: the bake reads OpParams
to place pits and chimneys, so nullptr would under-bound the cache and could
return Identity over a real pit.
- the search box is wider than Eval's, giving a superset of primitives.
The verdict is memoised per box (all twelve modifiers ask the same question), and
the cache is a SECOND per-worker cache so classification cannot disturb a live
generation's hot cache.
AUDIT C2, confirmed 2026-07-28, is fixed on the switch path in the same breath:
GetDensityWithParams now takes required ParamsFingerprint + LayoutVersion. The
alternative this audit section used to recommend -- add chunk Z to the key -- is
insufficient (Interleaved makes Alpha depend on chunk XY too) and destructive
(chunk XY is deliberately absent so gradient probes don't thrash the box, ARCH
8.10). The CRC is taken once per chunk where the params memo already lives, so
the per-voxel cost is two integer compares. The three test call sites pass it
too, so the oracle stops sharing the defect it tests.
Check 4 of the tunnel test no longer asserts "0 proved" -- that assertion would
now forbid the gain. It brute-forces every proved tile voxel by voxel instead and
reports the count, because a false verdict leaves no geometry and no collision
behind it.
The second debt (per-room ops can raise a modifier's amplitude above the strate
params a box bound reads) turned out to be DORMANT, not live: where the source
proves Identity the modifiers' gate never opens, and where it answers Both it
supplies no MaxCarveOverBox so nothing is provable anyway. It goes live the day
the source gains one. Written at the site.
Unbuilt.
