Near tiles legitimately need floor/ceiling boundary patches, but every hit query scanned the
tile's whole XY column. Direction-specific 3D cell bins conservatively index triangle bounds; the
existing predicates still decide every hit. Candidate visits per query -88..-99%; identical query
and hit counts. Hit-function cost ~1.7-1.9 -> ~0.35 s per FI/TN run. Near-ready @W12: FI 1.63 ->
1.52, TN 1.51 -> 1.38, VS 1.00 -> 0.92 s. All tile/whole hashes equal L103 (Clang/GCC W1/W8/W12).
The 24-28% "idle" is in the serial base-shape (~0.24 s) and far-parent (~0.13 s) phases; the
LOD0-1 drain is >= 99.4% busy. Fast tier PASS; Linux UE builds; FI Unreal arrival 1.96-1.98 s.

Off-grid census by caller (MC midpoints, skirts, far shells); all 63.0M sweep misses accounted
(1.9M exact-route fallbacks, 61.1M counted bound skips). Exact MC midpoint queries memoized by

all four strata (v216 unchanged); 0 added/removed crossings; 15 capture pairs pixel-identical.

L99 treated a missing exact-grid sweep sample as "no route here", so off-grid queries exposed the
FI/TN boundary band inside passage 1-2 (flat ceiling/floor). In-bound misses now evaluate the
exact route; a conservative route-feature bound still skips out-of-extent misses. Composition
order unchanged (graph -> bands -> passage -> stamps -> floor caps).
Comparison now counts added/removed crossings and triangles: 0/0 crossings on all four strates
(FI +56 triangles). 1-2 mid-tunnel: L98->L100 changes 32k px (L99 changed 1.14M).
Near-ready @W12 (L98/L99/L100): FI 2.62/1.78/2.05, TN 2.36/1.55/1.80, SW 1.17/0.95/1.04,

Clamping the passage-composition source density at -c (c=2..6 voxels, diagnostic, default off)

normal change (downstream composition consumes deep values). Source gradient at crossings is
distance-like at the median but has huge tails (FI p90 |grad| 512, max 894 vox/vox), so the

radius and relief padding. Stratum slicing only at LOD0-2 in FI/VS. Legacy sub-tile block

plinth, smooth-unioned into a flatField floor with a 0.55 m geometric rounding (measured fillets 0.73-1.17 m).
Exact radial/box interval bounds, a BVH, isTileShapeFree aware (0 brute-force misses, false-proof controls
rejected). Final-field route passes; whole-surface audit covers foot, cap and platform edges. Cold whole
view 0.524 s. Owner world unchanged. fast/medium/full PASS (Clang and GCC).

Opt-in --instrument-tile-drain records per-tile queue/dispatch/finish timelines, stage spans and counters
(proof skips, X8 lanes, GradAt/midpoint memo, skirts, FI cache stats); <2% when off. Measured: SW 13.3 and
FI 50.2 worker-s across LOD0-8, tails are work-saturated. FI sign-edge repair now computes in parallel and
publishes in sorted serial order (exact output): sign-edge 535 -> 47 ms, FI first tile 1.28 -> 0.85 s, near
ring 1.46 -> 1.04 s, whole view 6.09 -> 5.65 s. Proof block size, lane batching, SW midpoint memo and helper

Core.Caves.PrimitiveField v1, opt-in per strate (legacy TunnelNetwork assets stay legacy): solid host rock
and one smooth union of two elliptical spine tubes and an ellipsoid room, each intersected with its rising
floor by cubic smooth-max (W 2.4 m, measured fillet 0.70 m, no trailing floor cap). Bound in the L40 field
table and L42 capabilities, BVH feature candidates, isTileShapeFree aware, exact interval boxes (0 misses).
Capsule flood fill arrival -> departure passes (headroom >= 0.3 m, grade <= 15 deg); the generalized
whole-surface audit passes with its controls failing. Cold whole view 0.727 s, near ring 0.19 s. Graph
ordering/serialization changes are scoped to native caves (the flagged L47 demo is unchanged); verify

WorldAssemblySurfaceProfileV1 on the native SurfaceWorld recipe and plan; version 0 'natural' is omitted
from serialized identity, so the owner world is unchanged. periodicHills (seeded cosine hills, plan-time
grade <= 15 deg), mirroredRelief (cap mirrors the floor by lambda, clearance checked) and flatField share
one profile function for points, lattice classification and exact cosine-extrema intervals (0 interval
misses in brute-force audits). Style-override fixtures with planned passages. Cold whole view about 1.33 s

Measured first: 45% of FI tiles are all-air, yet FloatingIslandFieldV1 returned unknown for any box near
an island AABB (25,536 unknown boxes, 0 tile skips). Conservative ranges for island bodies, root lobes,
buttresses, connectors, surface detail and smooth-min budgets now let the shared box classifier prove FI
air/solid (216 tile skips; 28.6 M audited samples, 0 violations). The X8 path reuses its FI preflight
samples. LOD7-8 far-shell and column work is skipped outside per-tile island/connector influence bounds
(farHorizonVersion 4 -> 5). FI 16.74 -> 7.36 s (-56%), FI moving entering-tile p50 halved; SW unchanged.

Versioned capsule vein records (stable ID, resource ID, endpoints, radius, seeded irregularity) resolved
into the snapshot only when requested, placed beside the route and away from passages, landings and
landmarks (forced-passage control rejected). The bound field table gains materialAt (host + two resource
IDs + Q16 weights) behind a per-tile BVH; mesh export v2 carries per-vertex materials; a measurement-only
yield computes removed resource volume (0 on already-air space). With veins on, every density, mesh,

The demo tunnel's hard floor cap used a vertical Z - floorZ on a sloped Bezier floor, which is not a signed
distance, so marching cubes produced a staircase through the first 7 m (40-51 mm ripple, 82 mm steps). The
cap now uses the grade-normalised signed distance with a floor-adjacent bore re-application fading over the
entrance; mesh tile Z bounds include cavern bounds. New three-rail entrance audit: L46 fails, L47 passes.

The flagged SW demo's ramp (57 carves + 107 support pillars, visibly ribbed) becomes one cubic-Bezier
sweep: closest point by 17-point seed plus 5 Newton steps, a cubic floor profile, a rounded 2.6 m bore,
and a hard floor cap applied after unions and relief that only adds support where the field is air.
Optional resolved cavern-graph records (one room, one edge) enter canonical identity only when present;
their bounds extend World::isTileShapeFree. Reachability passes (L43 control fails), headroom 2.8 m,
floor ripple 1.8 mm (L45 ramp control fails at 17.9 mm), shape limits met; demo off: owner hashes

Stamp vocabulary v2; the flagged SW demo opens through a side-facing portal and a bent ramp (max 14 deg,
two landings) into a 17 x 15 m chamber with a rock dais. New reachability audit: a capsule surface search

L27 added passage support columns, but World::isTileShapeFree only bounded the route and bridge, so tiles
touched by a column could be approved for early native-only generation; depending on scheduling they used
that incomplete field or the compiled one (six LOD0 tiles differed between W1 and W12 at an SW camera near
the arrival mouth). The shape-free proof now includes a conservative envelope for every possible column.
The compiled world is unchanged (the old W1 variant), so no version bump. verify tiers gain a seeded
(SplitMix64 0x4c3434) random-camera W1/W8/W12 sweep across both recipes and several clip settings; it fails
before the fix and passes after. fast/medium/full PASS; cost within noise. Research R11: suspect review.

Stamp vocabulary v1 (carve ellipsoid/arch, fill pillar/dais) with smooth CSG and seeded relief; the
director resolves records (stable ID, strate, micrometre position, conservative bounds) from
hash(seed, strate, ID) with up to 512 candidates and rejects any that touch a passage mouth, walk corridor,
content face or ceiling/bedrock band; a stamp BVH skips tiles outside all bounds. No requests: canonical

SurfaceWorld, FloatingIslands and legacy evaluators sit behind one immutable densityAt adapter held in
a variant (no virtual call per sample); BindResolvedStratumFields builds a sorted strate table at world
setup, so DensityAt, native SW/FI sampling and ClassifyBoxDetailed no longer ask the strate manager per
sample. No arithmetic change: owner hashes identical to L37/L39 at W1/W12. Cost vs L39: FI -0.66%,
SW -1.31% (noise). verify fast/medium/full PASS (full re-run alone: 407 gates).

The passage mouth fade multiplied the signed carve distance by zero, which turned native rock into an
open surface (the reason earlier rounds stamped walk pads at mouths); it now blends between the
uncarved field and the full signed carve. The FI style-0 route followed a lifted grade envelope over
the crater (the "bridge"); it now runs on the rim and follows the native surface. New built-shape and
crease audits with thresholds frozen before the fix (L36 and box controls fail). 24/24 passage rows,
30/30 determinism, 16/16 invariants, 18/18 interface/ring. Unreal: one recipe setter (uncompiled).

The walk tread was built per segment as a one-sided density clamp, so its crossing with the native
field moved at segment joins (L35: 2.25-2.48 cm washboard). Treads now overlap up to 2 m as bounded
signed-distance slabs (0.06 cm residual). The FI mouth's crater detail and tread met without a smooth
join; v23 filters the local field, drops thin isolated solids and smooth-unions the tread with the
terrain. New floor ripple and mouth fragment/crease audits with L35 as failing controls. 24/24

The shared passage carve took the minimum of piecewise-linear capsules (scallops at joins) and added
wall relief on regular 8 m / 4 m octaves, which read as evenly spaced ribs. Interior sweep joins are
now Catmull-Rom smoothed and the relief uses irregular rotated 43/29/19 m scales; the natural wobble
remains. New axial ripple audit (0.125 m radius samples, 0.5-8 m periods): beaded control and L34
geometry fail, all 24 passage rows pass. FI mouth tread apron tapered. 30/30 determinism, 16/16
invariants, ring audits LOD0-8 pass; cost within noise.

Route planning for an upper SurfaceWorld failed on long candidate chords over steep relief; chords
are now capped to the arrival/departure radii on an 8 m centre grid with an origin-proximity cost
(21.5 m walk, about 4 deg). The departure passage starts at the SW ground and tunnels down through rock.
FI -> SW -> TN fixture: all 4 styles pass every passage audit on both compilers. FloorProfileBlend

Band faces now use signed distance to the displaced solid intervals, continuous across bands, so
MC interpolates the interface instead of terracing at density levels. The Gradient amplitude is
restored to width/8 (about 4 m peak-to-peak at 16 m). Ring/terrace audit at LOD0-8 on the FI floor and SW
ceiling passes; negative controls: L30 (rings) and L31 (flat) both fail. Hole/interface audits,
16 passage rows and 24/24 determinism pass. Evaluator 20. Cost vs L31 SW +1.9%, FI +1.5%.
