On the real FloatingIslands recipe, column caps sit inside anchor-island rock and native bedrock;
the old check sampled the route foot. The audit now samples each planned cap against the native
field (negative control: a cap moved into air is detected). The audit runner records requested vs
actual recipe and exits on mismatch. All 16 passage rows (4 styles x 2 recipes x 2 compilers) pass.
The readable shader uses a smooth tint. Interim: FI Gradient displacement capped at width/256
(flat floor, no contour rings); restoring real undulation is L32. Evaluator 19.

Core plans inter-strate passages from each upper strate's FStratePassageConfig for every
generator: Straight / Worm (the new natural default: meander, variable radius, rough walls) /
Spiral / Cascading. A naturalness audit (no >8 m flat runs, >=0.20 m wall relief) fails on L23's
smooth tube. FloatingIslands selects Spiral, with a deterministic unique anchor island (ordinal 2)
joined to the bedrock floor by a rock root. The SW arrival no longer stamps flat shelves.
Capsule audits 0 blocked / 0 unsupported / 0 grade failures, all styles. Full-view hashes
deterministic W1/W8/W12, Clang = GCC (reviewer re-run). Evaluator 10, FI geometry 5.
KNOWN: the FI helix renders as a spiral ribbon in open air around the pillar instead of a tunnel
enclosed in rock; fix next round. Unreal edits uncompiled.

FI geometry v3 drops the all-XY lower boundary seal that created false floors (3.5/8 m); the
ceiling comes from the shared VF_ApplyUpperBoundarySeal and AppendStratumBoundaryCeilings path
for every generator, at each strate's own configured upper boundary (owner: every strate has a
ceiling). Far-LOD ceiling continuity: 0 gaps at LOD4-8. SurfaceWorld bit-identical to L14
(14 configs + 24 m crossing); FI deterministic (28-row matrix); route parity and proofs pass.
Unreal: FI geometryVersion 2->3 and the shared upper-seal helper extracted (UBT compile needed on
the owner PC). Open: small ceiling holes; lower-stratum LOD ring steps seen through the FI void.

The capture tool gains --shade=readable (directional light, soft ambient, height tint) and an
optional --tile-edges overlay; display only. The L17 Core fix is NOT merged: its owner/Core chunk
scale change (8 m -> 4 m) moves every stratum and leaves the SurfaceWorld spawn camera over a void
(reviewer before/after renders). Kept on wip/l17-fi-scale. The FloatingIslands full-XY
boundarySeal cap is the likely real cause of the false floors and needs a separate minimal fix.

Linux offscreen capture (EGL/GLES pbuffer; llvmpipe in the sandbox) and an opt-in screen-space gate
for LOD>=3 (normal distance projected at each LOD's closest display distance, 1 px at 1440p =
0.61 mrad). The gate rejects the S13 octave-drop and stride-2 controls, fault injections, and a
vertical-vs-screen control. Finding: today's far meshes differ from the field by up to 92 px, and
LOD swaps snap mesa rims by tens of px (p50 0 px), a silhouette effect of plain LOD switching. The
octave cutoff was dropped: nothing qualified, and octaves are a small share of far time. Off-path
cost: reviewer interleaved W12 within noise vs L4 (+0.6% median). Hashes = L4.
Largest far lever measured: column work outside noise, 34% of far worker time (duplicate XY across tiles).
