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%.

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).
