experiment: LivingPlane repeatable + standalone UE runtime module (L164)

Readback barrier fix (GL_TEXTURE_UPDATE_BARRIER_BIT before glGetTexImage); check_repeatability.py compares full-field
checksums across query/capture settings - Intel GPU PASS (3b9d45905c7aafff), llvmpipe PASS, mismatch control fails.
New runtime module VoxelForgeLivingPlane (separate from generation): RDG global shader (Shaders/LivingPlane.usf),
ping-pong RGBA32F render targets, actor with WPO plane and object inputs, no CPU readback. Compiles in Linux UE 5.7.
Windows build: Source/VoxelForgeLivingPlane/*, Shaders/LivingPlane.usf, VoxelForge.uplugin. Setup: UE-SETUP.md.

+# AGENTS.md — VoxelForge (read automatically by Codex)
+
+You are the implementation agent. The orchestrator (Claude) writes each round's brief, reviews your diff against the
+code, and commits. The owner decides direction. Be warm and direct; credit what worked; say plainly what didn't.
+
+Read first, as the task needs: `CURRENT-STATE.md` (what ships, reference numbers, **closed experiments: don't reopen
+them without new evidence**), then `CODEMAP.md` and `ARCHITECTURE.md`. Round reports live in
+`Standalone/Research/WorldAssemblerM3/Linux*/REPORT.md`.
+
+## Standing rules (every round, unless the brief says otherwise)
+
+- Run as user `jahni`. Write only inside this plugin, plus `/home/jahni/VFHost` and `/home/jahni/UnrealEngine` when
+  the brief asks for a UE build. No installs, no system changes.
+- **No `git commit`, `push` or `stash`.** Leave changes in the working tree; the orchestrator reviews and commits.
+- Headless processes and builds: `taskset -c 0-11 prlimit --as=6442450944` (12 P-core threads, 6 GiB). Never use all
+  cores.
+- Unreal (UBT, the editor, commandlets): `taskset -c 0-11` only, **never `prlimit`** (CoreCLR fails). UE builds use
+  `-NoUBA -MaxParallelActions=4`, never while timing.
+- Stop any single run that passes 30 minutes. Logs go in `Saved/Linux/l<round>/`.
+- **Timing:** quiet machine only (check `uptime` first; load < ~1.5, nothing else building). L80 protocol: one warm-up
+  per binary, ≥5 interleaved runs, W8 and W12, all four owner layers. Every number states the window that produced it.
+- **Same world for everyone:** a seed must give the same world on every machine and worker count (Clang and GCC,
+  W1/W8/W12). Byte-identity with older versions is NOT required. If the output changes: bump
+  `WorldAssemblyEvaluatorVersion`, add baselines, and show captures.
+- Density sign: negative = solid, positive = air. Core voxels are 25 cm. Never mix metres and voxels without an
+  explicit conversion (v225 shipped a reach bug from exactly that).
+- The fast tier (`Standalone/Tools/verify/verify.py fast`) must stay green. Don't loosen an audit to make a change pass.
+
+## How to work
+
+1. **Count before you build.** Measure where the time or the failure actually is (stack sampler, census, counters).
+   State which parts are measured and which are inferred.
+2. **Suspect the measurement first.** An alarming or contradictory number is the instrument until a control rules it
+   out (A/A runs, an ablation that verifiably removes the work).
+3. **No fix without a root cause.** Reproduce it, trace it to its source, fix the cause. A guard that hides the symptom
+   is not a fix.
+4. **One change at a time,** each with its own check.
+5. **Subtract before you add.** Prefer removing work to reorganising it. The smallest edit that solves the problem.
+6. **Attack the premise.** When two fixes sharing one premise fail the same gate, write that premise in one sentence
+   and question it before trying a third. **After three failed fixes, stop:** it is probably the design, not the
+   hypothesis. Report it instead of trying fix #4.
+7. **Tests must be able to fail.** Name what would make each check fail. Add a negative control when you add an audit.
+8. **Refactors:** pin the behaviour (hashes), change the structure, prove nothing changed.
+9. **Verify before you claim.** Don't report a check as passed unless it ran on the final source. Say which checks
+   didn't run and why.
+10. Changes that speed things up go in the shared layer, so every generator benefits.
+
+## Report
+
+Write the round's `REPORT.md`, short and plain:
+- the result first;
+- what changed and why;
+- the measurements, with their windows;
+- the checks run, and those not run;
+- remaining risks.
+
+List any changed Unreal `Source/` files, because the owner compiles them on Windows.

The fixture rejects a target or floor outside the layout, a non-air empty-tile proof, or a floor inside the aligned level-0 ring.

+# VoxelForge current state
+
+As of 2026-10-31. L131 is on `assembler/world` as `8107196`; this L132 worktree is on `wip/l132-dispatch-truth`, starting at `ebae71b`. Current-state claims below point to their code or measured report.
+
+## What ships today
+
+- **Core:** evaluator version **227**. Unreal's `AVoxelWorld::bUseVoxelForgeCore` is opt-in and defaults to `false`; the legacy generator remains the default runtime path. [Core version](Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h), [runtime switch](Source/VoxelForge/Public/VoxelWorld.h), [L130 report](Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md).
+- **Verified owner4 generator dispatch (L132):** SW binds `SurfaceWorld-native` because the owner export contains a matching `SurfaceWorld.Heightfield2D` v2 plan. FI binds `compiled-analytic/FloatingIslands` because its `FloatingIslands.ClusterField` v0 layout has no matching native island plan. TN and VS bind `compiled-analytic/TunnelNetwork` and `compiled-analytic/VerticalShafts`; their legacy recipe IDs provide neither a `NativeCaves`/`NativeLattice` graph recipe nor native field capability. The L132 fast-tier report prints the binding and generated tile-center share at each owner strate. [Dispatch](Standalone/Core/src/ShapeWorldInternal.h), [adapter recipe checks](Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h), [L132 report](Standalone/Research/WorldAssemblerM3/Linux132/REPORT.md).
+- **Passages:** continuous smooth swept tubes with a continuous floor profile. L125 stamps conservative route slabs and outside sentinels into the tile cache; exact route geometry is still evaluated. All 21,425 route samples passed the open-air walk check; the nine-station floor probe's maximum root offset was 7.884 mm. L130 sets the shared influence reach to **1.0533 m** (0.75 m shell + 0.21 m relief + 0.50 m smooth-max support / 6 + 0.01 m margin), converted once from metres to Core voxels for the proof, feature, fallback, and off-grid bounds. [L125](Standalone/Research/WorldAssemblerM3/Linux125/REPORT.md), [L130](Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md).
+- **Streaming:** arrival uses a bounded startup apply burst: `voxel.StreamingStartupApplyBoost=1` by default, up to 24 visible meshes or 14 ms per frame for at most 30 seconds, until the initial desired set and walkable ring are ready. `voxel.StreamingFarApplySupplement=1` is also default-on: after the normal visible apply cap, at most one far result applies when under half the apply-time budget; it is inactive during the startup burst. Dynamic near reserve defaults on; coarse-first remains off; the legacy pending-result cap defaults off. The far-apply lane is Unreal-only. [CVar source](Source/VoxelForge/Private/VoxelWorld.cpp), [L121 report](Standalone/Research/WorldAssemblerM3/Linux121/REPORT.md), [architecture](ARCHITECTURE.md).
+- **Determinism:** proven on Linux with Clang and GCC at W1/W8/W12. L131's unchanged-output comparison covers owner4's SW/FI/TN/VS views in 24 compiler/worker cases; the canonical owner4/owner2 recipe matrix also passes. Windows determinism is unverified. [L131 checks](Standalone/Research/WorldAssemblerM3/Linux131/REPORT.md), [v227 canonical hashes](Standalone/Tools/verify/baselines/owner-hash/canonical/).

+## Current performance references
+
+Headless medians in seconds, five interleaved L80-style measurements per version in each cell. Near-ready means the complete LOD0–2 set; whole-view is the full requested view. Values below are the edited L131 binary; the paired pre-cleanup comparison is in the [L131 report](Standalone/Research/WorldAssemblerM3/Linux131/REPORT.md) and [timing summary](Saved/Linux/l131/timing/summary.json).
+
+| Stratum | Near-ready W8 / W12 | Whole-view W8 / W12 |
+|---|---:|---:|
+| S0 | 0.804 / 0.848 | 1.811 / 1.832 |

+| S3 | 0.917 / 0.884 | 1.887 / 1.782 |
+
+Across 40 paired runs per metric, the mean relative change from pre-cleanup L130 was −0.22% near-ready (95% CI −1.02% to +0.57%) and −0.29% whole-view (−1.04% to +0.46%); neither indicates a measurable slowdown. The machine gate was load 0.81 and 99.2% idle. [L80 protocol](Standalone/Research/WorldAssemblerM3/Linux80/REPORT.md), [runner and raw runs](Standalone/Research/WorldAssemblerM3/Linux131/RunL131Timing.py).
+
+The latest recorded Linux Unreal start-to-LOD0–2 values are L127's one run per stratum: S0 2.456 s, S1 2.231 s, S2 2.514 s, S3 2.221 s. L130 did not rerun UE startup or movement. Five L127 runs at 30 m/s, 12 s moving plus 5 s dwell, had median moving near coverage **40.22%**, far holes **3.46%**, tick p99 **10.80 ms**, and worst tick **13.27 ms**. After stopping, near coverage reached 100% and far holes reached 0%. These are the latest UE references, not v227 UE measurements.

+
+## Open gaps
+
+- Multiplayer world lifecycle is unfinished: seed/layout replication, authoritative modification RPCs, and serialized diff replay for late join are still open. See [ARCHITECTURE §9.5 and §9.7](ARCHITECTURE.md).
+- Determinism has not been verified on Windows. Linux Clang/GCC agreement does not establish MSVC agreement.
+- NullRHI measures residency and apply timing, not the first presented pixel or rendered enclosure. L127 also found four low-contrast views among 23 otherwise verified captures. [L121](Standalone/Research/WorldAssemblerM3/Linux121/REPORT.md), [L127](Standalone/Research/WorldAssemblerM3/Linux127/REPORT.md).
+- UE startup/movement numbers above predate L130's v227 reach change; there is no L130/L131 UE movement comparison.
+
+## How to verify
+
+- Build standalone Clang or GCC with [`Standalone/BuildLinux.sh`](Standalone/BuildLinux.sh), for example `bash Standalone/BuildLinux.sh --compiler=clang++-19 --variant=l132-clang --fp-contract=off --jobs=4`. The script pins CPUs 0–11 and applies `prlimit --as=6442450944` itself.
+- Fast tier: `python3 Standalone/Tools/verify/verify.py fast --out Saved/Linux/l132 --overall-timeout 1740`. It includes the L132 four-pose owner density-dispatch report; per-run logs and the summary stay under `Saved/Linux/l132`.
+- Canonical output baselines are the v227 files in `Standalone/Tools/verify/baselines/owner-hash/canonical/`. L131 also provides reproducible pre-cleanup identity matrices for owner4 tile hashes and owner4/owner2 canonical hashes under `Standalone/Research/WorldAssemblerM3/Linux131/`.
+- Timing follows L80: quiet machine, no overlapping build, one warm-up per version, five interleaved runs per stratum and worker count, W8/W12. Each headless run uses `taskset -c 0-11`, `prlimit --as=6442450944`, and a 1,740 s timeout. See [`RunL131Timing.py`](Standalone/Research/WorldAssemblerM3/Linux131/RunL131Timing.py).
+- Linux host build: `/home/jahni/UnrealEngine/Engine/Build/BatchFiles/Linux/Build.sh VFHostEditor Linux Development -Project=/home/jahni/VFHost/VFHost.uproject -NoUBA -MaxParallelActions=4 -Log=/home/jahni/VoxelM/Plugins/VoxelForge/Saved/Linux/l131/ubt.log`. Run Unreal without `prlimit`.

+# L162 — Living Plane
+
+The EGL/OpenGL 4.3 runner builds and passes its llvmpipe correctness and frame checks. The sandbox has no accessible DRM render node, so it did not run or report Intel GPU performance. The runner refuses `--device=gpu` here instead of falling back to software.
+
+## Implementation
+
+`LivingPlane.cpp` runs a ping-pong `RG32F` height/velocity field through a runtime-compiled GLSL compute shader. The damped wave update includes a weak foundation spring, a Gaussian sphere push, and an optional slow breathing force. The spring is needed because a persistent local push otherwise accelerates the zero-frequency height mode and sinks the whole plane. The sphere moves across the plane, stops, and bobs. A vertex-displaced mesh and lit sphere render to an EGL pbuffer-backed framebuffer and save as PNGs.
+
+The timestep is selected from the largest 2D grid eigenfrequency:
+
+`dt = 1.30 / sqrt(8*c*c/(dx*dx) + foundationStiffness)`
+
+The resulting spectral step ratio is 1.30, below the explicit update's 2.0 stability limit. The runner warms the compute kernel for eight unmeasured dispatches, then records one `GL_TIME_ELAPSED` query per requested simulation step in `timing.json`.
+
+The first-step equation audit also caught a GL state error during bring-up: frame rendering left the graphics program active before the next compute dispatch. `Dispatch` now binds the compute program before every step, so the audit fails if a frame silently stops simulation.
+
+Device selection enumerates EGL devices and uses `EGL_EXT_platform_device` for an accessible Intel render node first. On this host, the known integrated device is Intel on `renderD128`. Automatic mode falls back to a surfaceless Mesa context with `LIBGL_ALWAYS_SOFTWARE=1`; explicit GPU mode fails when no accessible hardware node is present. EGL does not expose Vulkan's integrated/discrete enum, so Intel vendor/render-node identity is the selection heuristic.
+
+The Unreal handoff is in [UNREAL-MAPPING.md](UNREAL-MAPPING.md). It keeps the prototype render-only and describes the density mapping if the surface later needs to affect voxel queries. No Unreal `Source/` files changed.
+
+## Measurements and checks
+
+- Built with `Experiments/LivingPlane/build.sh` using the installed EGL, desktop GL, and libpng development files; no shader compiler or package install was needed.
+- Final llvmpipe run: 128² field, 360 steps, `dt=9.56814 ms`, spectral ratio 1.30. The first-step equation audit and finite-field/dynamics audit passed. Final field range was −0.139533 m to +0.0366704 m. It wrote 16 128×128 PNGs and a JSON file containing 360 per-step query samples. The frames were inspected; the moving sphere and wake are visible.
+- Auto-selection smoke check: 32², 12 steps; selected llvmpipe and passed both audits. Breathing smoke check: 64², 180 steps with `--breathing=on`; passed both audits.
+- Negative device-selection control: `--device=gpu` returned an error because the sandbox has no accessible EGL DRM render node.
+- Existing fast verification tier passed: 278.9 seconds, ending in `SUMMARY PASS`. Its build and logs are under `Saved/Linux/l162/verify/` and `Saved/Linux/l162/`.
+- The llvmpipe `GL_TIME_ELAPSED` samples are preserved in JSON but are software-driver query values, not GPU timings. The requested hardware timing pass remains to be run outside the sandbox.
+- No Unreal build was run; no Unreal `Source/` files changed.
+
+## Intel GPU pass
+
+Run these from the plugin root as `jahni`. The frame run writes 512×512 PNGs to `Saved/Linux/l162/gpu-frames-512/`; the two timing runs write `timing.json` with one GPU query per step and skip PNG capture. They still read the field for the first-step and final-state correctness audits.
+Before the timing runs, check `uptime` and run them on a quiet machine (load below about 1.5, with no other build active).
+
+```sh
+uptime
+taskset -c 0-11 prlimit --as=6442450944 -- timeout 1740s ./Saved/Linux/l162/living-plane --device=gpu --size=512 --steps=1800 --capture-every=12 --out=Saved/Linux/l162/gpu-frames-512
+taskset -c 0-11 prlimit --as=6442450944 -- timeout 1740s ./Saved/Linux/l162/living-plane --device=gpu --size=512 --steps=1800 --capture-every=0 --out=Saved/Linux/l162/gpu-timing-512
+taskset -c 0-11 prlimit --as=6442450944 -- timeout 1740s ./Saved/Linux/l162/living-plane --device=gpu --size=1024 --steps=1800 --capture-every=0 --out=Saved/Linux/l162/gpu-timing-1024
+```
+
+Encode the captured sequence as MP4 with:
+
+```sh
+ffmpeg -y -framerate 30 -i Saved/Linux/l162/gpu-frames-512/frame_%06d.png -c:v libx264 -pix_fmt yuv420p Saved/Linux/l162/living-plane-512.mp4
+```
+
+## Files and remaining risk
+
+The only changed file outside `Experiments/LivingPlane/` is `.gitignore`, which now allows `Experiments/` and its contents. GPU timings and Intel render-node selection remain unverified until the commands above run on the host outside this sandbox.
+
+## Intel GPU pass (run by the orchestrator outside the sandbox, 2026-11-02)
+
+- The device was selected correctly: `Mesa Intel(R) Graphics (ADL GT2)`, OpenGL 4.6, `/dev/dri/renderD128`. 512²,
+  1,800 steps, 151 frames; the equation audit passes. MP4: `Saved/Linux/l162/living-plane-512.mp4` (local).
+- **The `GL_TIME_ELAPSED` per-dispatch values (~0.0001 ms) are not credible** for 262k cells, so they aren't
+  reported as timings.
+- Wall-time difference between 1,800 and 200 steps, divided by the 1,600 steps (start-up cancels out; this includes
+  submission, so it's an upper bound): **0.080 ms/step at 512²** and **0.292 ms/step at 1024²**.
+- Visual read: the effect is very subtle in the current render (a slight dip under the sphere, faint rings). It needs
+  a larger push amplitude, grazing light or height colouring, and a closer camera to read.
+
+## L163 — readable, living plane
+
+The plane now reads as rolling terrain, and the objects leave visible troughs and wakes. `alive` adds travelling
+breathing and a viscoelastic imprint that remains after lift-off. The simulation still runs in one GPU dispatch per
+step; CPU work only supplies the two object states.
+
+`LivingPlane.cpp` now keeps the dynamic displacement, velocity, and imprint in an `RGBA32F` ping-pong field. The
+surface shader adds broad static terrain relief, calculates normals from relief plus displacement, and uses grazing
+light, elevation colours, slope tint, and 7.5 cm contour bands. The camera follows the first sphere at a closer angle.
+The wake scene rolls the first sphere, pauses and wobbles it, lifts it, then sends a second sphere through the wake.
+The alive scene runs that same sequence with low-frequency travelling swells and a decaying contact imprint. Its
+defaults are breathing strength 4.8 m/s², imprint capture 0.15 m/s, recovery time 6 s, and maximum imprint depth
+0.34 m. These values have command-line overrides.
+
+The timer query check found no early read or reuse in L162: it allocated a unique query per step, called `glFinish`,
+then read every result. The saved Intel/Mesa 25.0.7 samples are 0 or 52 ns for most dispatches (512² median 0,
+p95 52 ns; largest sample 17.552 µs), which cannot be a credible per-dispatch cost. The old usage did not reuse
+query objects, so lifetime is not the cause; the saved data point to Intel/Mesa's timer-query reporting or timing
+scope, but the sandbox cannot isolate which. L163 uses a 64-query ring, reads each query before reusing its slot,
+checks availability after `glFinish`, and records `GL_QUERY_COUNTER_BITS`. On llvmpipe the availability check passed
+with 64 counter bits and zero waits. The Intel query result still needs the GPU diagnostic command below.
+
+### Measurements and checks
+
+- llvmpipe wake: 128², 600 steps (`dt=9.56814 ms`, 5.741 s simulation window), 151 frames at 30 fps. First-step
+  equation audit and timer-query lifetime check passed; final displacement range was −0.177488 m to +0.104854 m.
+- llvmpipe alive: same grid, steps, and window; equation audit and timer-query lifetime check passed. Final
+  displacement range was −0.200437 m to +0.115904 m, with a −0.111667 m stored imprint.
+- llvmpipe cost: 512², 1,800 steps, `--queries=off`, no frame capture: **0.767473 ms/step** in one timed
+  simulation-loop window. `timing.json` includes dispatch submission, the step-0 equation readback, and final
+  `glFinish`, but excludes setup and frame capture. This is a software-renderer measurement, not the Intel GPU cost.
+- Both five-second llvmpipe previews are in `Saved/Linux/l163/llvmpipe-wake.mp4` and
+  `Saved/Linux/l163/llvmpipe-alive.mp4`. They are 128² review previews; use the GPU commands below for the owner
+  videos.
+- Equation-audit negative control: a temporary copy with its expected first-step height forced to zero exited FAIL
+  at actual −0.0488777 m. The final source passes that same check.
+- The fast verification tier passed in 278.5 s. Build and logs are under `Saved/Linux/l163/verify/`.
+- No Unreal `Source/` files changed and no Unreal build ran.
+
+### Intel GPU run
+
+Run from the plugin root as `jahni`. First build the runner. For timed runs, check `uptime` and keep the machine
+quiet. The wall-time field is valid only when `--capture-every=0`; use `--queries=off` for the step-cost measurement.

+

+`gpu-query-check-512/timing.json` contains query counter bits, waits before slot reuse, availability status, and raw
+per-step query samples. The sandbox has no accessible Intel DRM node, so the current Intel step cost and new query
+diagnostic remain unmeasured here.
+
+### L163 Intel GPU pass (run by the orchestrator, 2026-11-02)
+
+- Intel ADL GT2 (Mesa 25.0.7, `renderD128`): wake and alive scenes, 512², 2,400 steps, 151 frames each; equation
+  audits PASS. Videos (local): `Saved/Linux/l163/living-plane-wake-512.mp4`, `living-plane-alive-512.mp4`.
+- Step cost, alive scene, 512², 1,800 steps, no capture: **0.172 ms/step** with queries off, 0.152 ms/step with
+  queries on (batch wall time per step).
+- The Intel `GL_TIME_ELAPSED` median is still 0 with 64 counter bits and the ring/availability checks passing. That
+  looks like a Mesa/Intel reporting issue; use wall time.
+- **Open issue:** the same scene with the same steps gave different final fields (min −0.637 m with queries off vs
+  −0.327 m with queries on). Something depends on more than the step index (e.g. wall-clock time); investigate.
+
+## L164 — repeatable field readback and UE runtime actor
+
+**Result:** the repeatability check passes on llvmpipe, and the new `VoxelForgeLivingPlane` runtime module compiles
+in the Linux UE 5.7 host. The surface actor is independent of VoxelForge generation and sends no field readback to
+the CPU.
+
+### Repeatability finding
+
+`uTime` is `Step * dt`, and `GetBodiesAt` receives that same value. Neither the object schedule nor the breathing
+force uses wall time or a rendered-frame counter. Every compute step already issued an image-access barrier before
+the next ping-pong image read. The defect was on the diagnostic side: the step-zero and final `glGetTexImage`
+readbacks followed shader image writes without `GL_TEXTURE_UPDATE_BARRIER_BIT`. The Khronos OpenGL specification
+requires that barrier for `GetTexImage` to observe earlier shader writes ([§7.12](https://registry.khronos.org/OpenGL/specs/gl/glspec44.compatibility.pdf)). Query/capture pacing could therefore affect the reported field values without changing any simulation input. The barrier is now issued before both readbacks.
+
+`check_repeatability.py` runs the same 512² alive scene for 1,800 steps twice: queries off with no captures, then
+queries on with captures every 900 steps. The checksum covers every final RGBA32F field value using canonical
+little-endian float bytes.
+
+- llvmpipe, queries off/capture off: field range −0.637382 m to +0.109308 m; checksum
+  `1ba08f5dafc01f82`.
+- llvmpipe, queries on/capture every 900: the same range and checksum; equation and timer-query audits pass; three
+  frames written.
+- Negative control: changing one saved checksum made the comparison exit 1 with `FAIL field checksum mismatch`.
+- The llvmpipe runs were each one 1,800-step simulation-loop window. Logs and JSON are under
+  `Saved/Linux/l164/repeatability/`.
+
+The Intel run is not available in this sandbox. The owner should repeat the checksum comparison on the GPU to
+confirm that the missing transfer-readback barrier accounts for the earlier Intel min mismatch:
+
+```sh
+python3 Experiments/LivingPlane/check_repeatability.py --device=gpu --out=Saved/Linux/l164/gpu-repeatability
+```
+
+### Unreal implementation and checks
+
+The plugin descriptor adds a separate `VoxelForgeLivingPlane` runtime module. Its RDG global shader is in
+`Shaders/LivingPlane.usf`; module startup maps `/Plugin/VoxelForgeLivingPlane` to the plugin shader directory. The
+actor owns two UAV-capable RGBA32F render targets, advances them at the stable fixed step, and supplies the current
+texture to a movable plane mesh material. Its Blueprint/C++ object input includes world position, radius, velocity,
+base push, and active state. The CPU converts those values to plane-local metres and uploads uniforms; it does not
+read the field back. The ignore rules now include `Shaders/` so that the shader ships in the worktree diff.
+`Experiments/LivingPlane/UE-SETUP.md` gives level setup, the full material graph, and object driving steps.
+
+- Linux UE 5.7 `VFHostEditor Linux Development`: **PASS**, final incremental build compiled
+  `VoxelForgeLivingPlaneActor.cpp` and linked `libUnrealEditor-VoxelForgeLivingPlane.so`. Command used
+  `-NoUBA -MaxParallelActions=4`, `taskset -c 0-11`, and no `prlimit`. Log:
+  `Saved/Linux/l164/ue-build-final.log`. The initial attempt exposed an incorrect RDG texture registration overload;
+  it had already compiled `VoxelForgeLivingPlaneModule.cpp` and the generated module code. The corrected final
+  build passed.
+- The host `PluginDeps/VoxelForge/Source` and `.uplugin` links were temporarily pointed at this worktree for the
+  build and restored to `/home/jahni/VoxelM/Plugins/VoxelForge` afterward. The temporary shader link was removed.
+- Standalone build, final repeatability comparison, checksum-mismatch negative control, plugin JSON parse, and
+  `git diff --check` passed.
+- Not run: fast generation verification (generation sources are untouched), Intel GPU checksum comparison, or a UE

+# Living Plane in Unreal Engine 5.7
+
+`VoxelForgeLivingPlane` is a separate runtime module. It does not call the VoxelForge terrain generators and it does not read the simulated texture back to the CPU. The actor owns two transient `RGBA32f` render targets and advances them with an RDG compute pass. The CPU sends object state and fixed-step uniforms only.
+
+## Add it to a level
+
+1. Enable the VoxelForge plugin and restart the editor so the `VoxelForgeLivingPlane` runtime module and its shader mapping load.
+2. Create a material named `M_LivingPlane` using the graph below.
+3. Place `VoxelForgeLivingPlaneActor` in the level. Assign `M_LivingPlane` to **Plane Material**.
+4. Keep the actor on the world XY plane with unit actor scale. `Plane Length Meters` controls the mesh width and simulation width; the built-in plane mesh is scaled to that size.
+5. The actor creates and clears its two GPU state targets on `BeginPlay`. The mesh has collision disabled; this surface is render-only and does not change VoxelForge density or collision queries.
+
+## Material graph
+
+Use a Surface, Opaque material. The actor binds these parameters on its dynamic material instance:
+
+- `LivingField`: Texture Object Parameter. The texture is the current RGBA32f simulation state; **R** is displacement in metres.
+- `PlaneLengthMeters`: Scalar Parameter.
+- `FieldSize`: Scalar Parameter, equal to the render target width and height.
+
+For World Position Offset:
+
+1. Read `LivingField` at `TextureCoordinate[0]` with a Texture Sample.
+2. Multiply its **R** output by `100` to convert metres to Unreal centimetres.
+3. Append `(0, 0)` to that value, making `(0, 0, heightCm)`, and connect it to **World Position Offset**.
+
+For the displaced normal, sample the height at four UV offsets using the same texture object:
+
+- Left/right UV: `TexCoord + (-1/FieldSize, 0)` and `TexCoord + (1/FieldSize, 0)`.
+- Down/up UV: `TexCoord + (0, -1/FieldSize)` and `TexCoord + (0, 1/FieldSize)`.
+- `dHdx = (Right.R - Left.R) * FieldSize / (2 * PlaneLengthMeters)`.
+- `dHdy = (Up.R - Down.R) * FieldSize / (2 * PlaneLengthMeters)`.
+- Make and normalize the tangent-space vector `(-dHdx, -dHdy, 1)`, then connect it to **Normal**.
+
+The built-in plane's U/V tangent directions align with local X/Y. Use a neutral base colour and roughness around `0.7` to start. The graph assumes a horizontal plane; add a local-to-world transform if the plane needs arbitrary rotation.
+
+## Drive objects
+
+`ObjectInputs` has two slots. Each `FVFLivingPlaneObjectInput` contains world position in centimetres, world velocity in centimetres per second, radius in centimetres, base push acceleration in metres per second squared, and an active flag. Blueprint can use **Set Object State** or set the array entry; C++ can call the same method. Set the object's center about one radius above the plane while it contacts it, and mark the slot inactive after lift-off.
+
+The compute shader uses the radius to scale the Gaussian contact footprint. The original wave equation keeps the L163 wave speed, damping, foundation spring, travelling breathing force, and recovering imprint. The base push acceleration supplies the object force; lateral speed adds `0.25 m/s²` per `1 m/s`, and downward speed adds `0.5 m/s²` per `1 m/s`. Upward velocity does not add force. Object positions and velocities are transformed into the plane's local frame and converted from centimetres to metres before upload.
+
+Each step uses `dt = 1.30 / sqrt(8*c*c/(dx*dx) + foundationStiffness)`, with `dx = PlaneLengthMeters / FieldSize`. Simulation time passed to breathing is the fixed step index times `dt`. Game-thread delta time only determines how many fixed steps are queued; no GPU field data is read back in the normal path.
+
+## Build files
+
+The owner's Windows build needs every added source and shader file:
+
+- `Source/VoxelForgeLivingPlane/VoxelForgeLivingPlane.Build.cs`
+- `Source/VoxelForgeLivingPlane/Public/VoxelForgeLivingPlaneActor.h`
+- `Source/VoxelForgeLivingPlane/Private/VoxelForgeLivingPlaneActor.cpp`
+- `Source/VoxelForgeLivingPlane/Private/VoxelForgeLivingPlaneModule.cpp`
+- `Shaders/LivingPlane.usf`
+
+The `VoxelForge.uplugin` runtime-module entry must ship with them.

+# Unreal mapping note
+
+The prototype stores height, vertical velocity, a recovering imprint, and a spare
+channel in a pair of `RGBA32F` textures. A world-owned Unreal component can keep
+equivalent transient render graph textures and advance them with a compute pass. It
+should own simulation time and clear or restore its buffers when the world is recreated.
+
+The sphere path becomes a world-space interaction event: position, contact radius,
+and impulse strength are supplied to the compute pass. For multiplayer or deterministic
+replay, replicate the compact events and simulation tick, or record the resulting field;
+do not assume that independent GPU floating-point runs will produce byte-identical
+textures.
+
+The rendered top surface can remain a render-only displaced mesh. If it must participate
+in voxel collision or queries, its height must also reach the density evaluator. For a
+height `h(x,y)`, the plugin's density convention is negative inside solid and positive
+in air, so the plane's signed density is `z - h(x,y)`. Keep this calculation in metres
+until the existing voxel/Core boundary converts with the active voxel size (25 cm by
+default); do not mix metre distances and voxel counts in the wave solver.
+
+The current sample is an isolated visual field. Wiring this into `AVoxelWorld` would
+need an explicit owner for simulation lifetime, collision/update cadence, save/load,
+and the replication policy before it could affect shipped terrain.
+
+## L164 render-only Unreal implementation
+
+`Source/VoxelForgeLivingPlane/` now implements this render-only path as a separate
+runtime module. `AVoxelForgeLivingPlaneActor` owns two UAV-capable RGBA32F render
+targets, advances the wave, breathing, and imprint equations with an RDG global shader,
+and binds the current texture to its plane material. Blueprint/C++ supplies object
+position, radius, velocity, push, and active state. The actor does not call the
+generation modules and does not read the field back. Level setup and the material graph
+are in [UE-SETUP.md](UE-SETUP.md).

+# VoxelForge — open read-only review: what should be done and focused on now?
+
+You are an outside reviewer. **Do not edit, create or delete any file, and do not build or run anything.** Read the
+repository and its reports and reason. Be thorough; mark each claim as [CODE] (with file:line), [MEASURED] (from a
+report), or [INFERENCE].
+
+## The project, in the owner's words and goals
+
+- VoxelForge is a UE5 density-field voxel plugin for a **multiplayer** game. The world is made of stacked "strates"
+  (layers) linked by tunnels. The standalone C++ generator is "Core" (`Standalone/Core`), and it is also compiled into
+  Unreal. Read `CLAUDE.md`, `CODEMAP.md`, `ARCHITECTURE.md`, `GDD.md`, `COMPOSER-NOTES.md` and `fable-idea.md` at the
+  plugin root for the game and design intent. The research reports are in
+  `Standalone/Research/WorldAssemblerM3/Linux*/REPORT.md` and the `Astra*/` reviews.
+- Owner goals stated over time:
+  - the near terrain (LOD0–2) ready in ~1 s on arrival, then far terrain keeps filling in at low priority;
+  - same seed gives the same world on every machine (byte-identity with older versions is NOT required);
+  - smooth for VR and high-speed travel;
+  - all generators (surface, floating islands, caves, dreamcore/liminal, etc.) working in Core;
+  - the system should eventually *invent* strates and worlds from tagged authored content plus a seed;
+  - keep things simple and avoid over-complication.
+- The current main line is branch `assembler/world`.
+
+## Your task
+
+Look at the whole: code, reports, design docs, and the direction of the last few dozen rounds. Tell the owner what
+should be done and focused on now, whatever it is. That may be performance, features, generation quality, gameplay
+foundations, architecture, technical debt, tooling, process, or stopping something. Don't assume the recent focus is
+the right one; question it if the evidence says so.
+
+Answer:
+1. **Where the project actually is**: what works, what's fragile, what's missing for the game to exist.
+2. **The top 3–5 things to focus on now**, ranked, each with why, a rough size, what "done" looks like, and how to
+   tell it worked.
+3. **What to stop or deprioritise**, and why.
+4. **Risks or debts** that will bite later if ignored.
+
+Write plain Markdown, at most ~1,500 words, readable by a non-specialist owner (explain jargon briefly).

+[INFERENCE] **Focus now on a small, persistent multiplayer descent, supported by end-to-end Unreal performance work.** VoxelForge has substantial terrain technology. The larger uncertainty is whether it delivers a reliable, interesting shared expedition. Another sequence of tunnel optimizations will not resolve that.
+
+Read-only review of `assembler/world` at `044cd6d`; no files changed and no builds, tests, or project execution. [CODE] identifies repository evidence; design-document references establish intent, not implementation. [MEASURED] means reported results, not independently reproduced measurements.
+
+**1. Where the project actually is**
+
+[CODE] **Core is real and integrated, but generator implementation remains mixed.** Unreal compiles the canonical standalone sources through validated wrappers. Core dispatches to surface, floating-island and native graph evaluators, with a legacy-generator fallback when appropriate. That is useful coverage, but does not mean every family has a complete native implementation. See [VoxelForgeCore.Build.cs:15](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForgeCore/VoxelForgeCore.Build.cs:15) and [ShapeWorldInternal.h:600](/home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:600).
+
+[MEASURED] **Passage correctness and speed have improved substantially.** L109 simplified tunnels and removed support-restoration machinery, reducing floating-island and tunnel-network near-generation times by approximately 31–38%. L125 reports 21,425/21,425 open route samples, a maximum sampled floor offset of 7.884 mm, and matching cross-compiler/worker hashes. These are meaningful engineering achievements. [L109](Standalone/Research/WorldAssemblerM3/Linux109/REPORT.md), [L125](Standalone/Research/WorldAssemblerM3/Linux125/REPORT.md).
+
+[MEASURED] **The one-second player experience is not achieved.** L125’s standalone near-ready medians were approximately 0.78–1.03 seconds. L127’s Unreal startup took 2.22–2.51 seconds; at 30 m/s, median near coverage fell from 43.36% to 40.22% after the smooth-tunnel merge. Both versions recovered after stopping. L130 found no measurable timing improvement and skipped Unreal movement. These are different workloads; subtracting their times would not isolate a particular overhead. [L125](Standalone/Research/WorldAssemblerM3/Linux125/REPORT.md), [L127](Standalone/Research/WorldAssemblerM3/Linux127/REPORT.md), [L130](Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md).
+
+[CODE] **Multiplayer foundations exist; the multiplayer lifecycle remains unfinished here.** There are season hashes, local terrain-edit entry points, and streaming-anchor infrastructure. The architecture explicitly leaves join replication, authoritative edit messages, late-join snapshots and networked season changes open. The edit entry point directly dispatches to local modification paths. [VoxelWorld.h:574](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelWorld.h:574), [VoxelWorld.cpp:15771](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:15771), [ARCHITECTURE.md:2408](/home/jahni/VoxelM/Plugins/VoxelForge/ARCHITECTURE.md:2408).
+
+[CODE] **The composer is more than a proposal, but less than the full content vision.** It rolls candidates, measures them and rejects failures. The intended system additionally combines tagged geometry, materials, decorations, creatures and audio; theme coherence remains an open design item. [VoxelSeasonManifest.cpp:2523](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelSeasonManifest.cpp:2523), [COMPOSER-NOTES.md:1512](/home/jahni/VoxelM/Plugins/VoxelForge/COMPOSER-NOTES.md:1512).
+
+[INFERENCE] **This repository demonstrates a capable terrain platform, not yet a validated game loop.** I cannot establish what gameplay exists outside the plugin. The GDD itself identifies “Is the descent fun?” as its first unresolved question. [GDD.md:441](/home/jahni/VoxelM/Plugins/VoxelForge/GDD.md:441).
+
+**2. Ranked priorities**
+
+All sizes below are [INFERENCE]: rough focused engineering estimates, excluding substantial art production.
+
+**1 — Deliver one multiplayer expedition that survives reconnecting. Size: 3–6 weeks.**
+
+[INFERENCE] Use two contrasting strates and their connecting tunnel. Two players descend, find one destination, uncover or collect something, return, and retain their changes after restart. Include a third player joining after terrain has changed. Avoid expanding immediately into the city economy or community backend.
+
+[INFERENCE] The necessary foundation is a server-approved world identity, ordered authoritative edits, a saved snapshot plus subsequent edits, and collision around separated players. Give edits stable identifiers so retransmission cannot apply them twice. Reuse the existing local edit and anchor systems.
+
+[INFERENCE] **Done:** host/client edits agree; a late joiner reconstructs the same terrain; restart preserves it; incompatible world versions fail clearly; remote players have ground when away from the host.
+
+[INFERENCE] **Success:** a complete shared expedition without terrain disagreement, lost progress or collision failures—and players can explain what made them want to descend again. This tests the project’s central assumptions much earlier than a complete RPG would.
+
+**2 — Close the Unreal arrival and movement gap. Size: 1–3 weeks initially.**
+
+[MEASURED] L122 found idle generation capacity while admission was blocked; L123 measured approximately 19 ms from region request to game-thread observation despite sub-millisecond median compilation. Simple lookahead and admission relaxations failed their combined coverage/frame-time gates. L121’s modest extra far-apply lane did improve far coverage. [L121](Standalone/Research/WorldAssemblerM3/Linux121/REPORT.md), [L122](Standalone/Research/WorldAssemblerM3/Linux122/REPORT.md), [L123](Standalone/Research/WorldAssemblerM3/Linux123/REPORT.md).
+
+[INFERENCE] First establish one current-build, rendered Unreal baseline on intended hardware. Measure arrival through **visible terrain and usable collision**, then walking, 30 m/s travel, turns, teleporting and edits. Record near coverage, far gaps, frame-time spikes and memory separately. NullRHI measurements, which omit rendering, cannot certify VR comfort.
+
+[INFERENCE] Investigate region completion, admission and publication before another broad density rewrite. A game-thread continuation is a candidate experiment, not a proven solution; keep world mutation on its owning thread.
+
+[INFERENCE] **Done:** approximately one-second LOD0–2 readiness on the agreed hardware, safe collision, steadily filling far terrain, and an explicit movement-coverage target without worsening frame spikes. **Success:** repeated rendered runs meet those limits, including with remote-player collision work. Do not redefine “ready” as only the nearest handful of tiles.
+
+**3 — Turn generator breadth into playable variety. Size: 2–4 weeks for the first content slice.**
+
+[INFERENCE] Establish a compact capability matrix for each family: Core dispatch, entrances/exits, interior connectivity, edits, materials/content, far terrain and performance. Include dreamcore/liminal explicitly; motif generation alone does not establish a convincing anomalous place.
+
+[MEASURED] L58 illustrates the distinction: its lattice route passed reachability checks, but the review described a corkscrew tunnel rather than the intended open vertical shaft. Technical validity and identity are separate acceptance criteria. [L58](Standalone/Research/WorldAssemblerM3/Linux58/REPORT.md).
+
+[INFERENCE] Extend the existing offline composer with a small tagged library: a grounded cave, an island environment and one liminal identity, each with coherent materials, sound and a destination. Preserve owner review before publishing a season.
+
+[INFERENCE] **Done:** several seeds produce recognizably different, coherent places with findable progression and usable encounter spaces. **Success:** players navigate them without developer guidance and distinguish their identities without reading labels. Expand families after this works.
+
+**4 — Consolidate the evidence and remove obsolete complexity incrementally. Size: 2–4 days, then ongoing.**
+
+[INFERENCE] Maintain one short current-state page: shipped behavior, open defects, active baseline, hardware and next acceptance test. Keep historical reports as history. Remove rejected experimental paths when they no longer serve a specific comparison; extract stable responsibilities when touching oversized files.
+
+[INFERENCE] **Done:** a contributor can identify the current evaluator, runtime path, multiplayer gaps and performance limits without reconstructing 130 rounds. **Success:** new work no longer repeats rejected experiments or treats old measurements as current.
+
+**3. Stop or deprioritise**
+
+- [INFERENCE] **Pause open-ended tunnel micro-optimization.** L125/L126 missed the older speed bar; L130’s reach correction produced no measurable speedup. Keep correctness fixes, but require a current cost account and a bounded experiment before further optimization. [MEASURED: L126](Standalone/Research/WorldAssemblerM3/Linux126/REPORT.md), [L130](Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md).
+- [INFERENCE] **Do not implement Astra recommendations mechanically.** Astra1’s support-heavy model predates L109’s simplification. Astra2/3 offer hypotheses, not measured wins for today’s code. Re-profile before adopting them.
+- [INFERENCE] **Defer GPU generation, a mesher replacement, elaborate discovery systems and large-scale backend work.** None currently resolves the missing shared expedition.
+- [INFERENCE] **Stop requiring old-version byte identity for deliberate generation changes.** Preserve peer agreement within a version and explicit versioned saves; permit reviewed geometry improvements.
+
+**4. Debts that will bite later**
+
+[INFERENCE] **Determinism needs a deployment contract.** Linux Clang/GCC and worker-count agreement is strong evidence, not proof across every intended machine. Include Windows/compiler/CPU combinations actually supported. World identity must cover evaluator, content, layout, scale and edit state—not merely seed. [MEASURED: L130](Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md).
+
+[CODE] **Scale and fallback complexity remain active integration risks.** Core is opt-in, and runtime queries bridge different coordinate conventions. [VoxelWorld.h:300](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelWorld.h:300), [VoxelWorld.cpp:15612](/home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelWorld.cpp:15612). [INFERENCE] Test edits, content placement and collision across those boundaries before broadening authoring.
+
+[INFERENCE] **A passing route audit does not prove a whole strate is enjoyable, connected or suitable for six-player combat.** Retain geometric checks, but add actual traversal, destination discovery and encounter-space evaluation. Those are now more valuable than another polished tunnel benchmark.

-# L129 — tunnel reach
-
-**Decision: no-go for performance.** The 2 m candidate passed the geometry checks, but it was slower than both timing references and failed every UE movement comparison. The count pass also found a units mismatch in v225's reach bounds, so the requested physical reach cannot be cut cheaply against the source as it stands.
-
-## What the reach includes
-
-The 4.0 m term is the signed-distance influence cutoff outside the bore. The bound adds 0.21 m for wall relief and reserves 0.125 m for the 0.50 m smooth corner (`width/6` is about 0.083 m). The plain shell is 0.75 m thick, so its minimum reach with relief is 0.96 m. The larger term wins: `r + max(R + 0.21 + 0.125, 0.75 + 0.21) + 0.05 m`. At `R=4 m` and the maximum `r=3.5 m`, that is 7.885 m.
-
-The mouth blend is 5 m **along the route**, not an added radial reach. The open-air half-pipe's side wall is 1 m high; its rounded crest uses the same reach. L129 leaves the 0.75 m shell rule, smooth floor `h(s)`, rounded crest, and grade limit unchanged. The highest audited grade was 10.695°.
-
-## Counts before the build
-
-Counts cover the four owner strata at LOD0–2, with 993 route segments. “Pairs” are route-segment/sample checks; “support” is unique per-passage samples inside the distance cutoff. The v225 model's 29.87M pairs is close to the measured source profile's 29.41M.
-
-| Reach and bounds | Pairs (M) | Support samples (M) | Overlap pairs (M) | Feature / proof-active tiles |
-|---|---:|---:|---:|---:|
-| v225 as coded, nominal 4 m | 29.87 | 8.57 | 20.90 | 721 / 677 |
-| 4 m, physical bounds | 124.97 | 11.72 | 46.64 | 826 / 791 |
-| 3 m, physical bounds | 87.06 | 8.84 | 30.42 | 787 / 764 |
-| 2 m, physical bounds | 56.86 | 6.32 | 18.48 | 755 / 729 |
-| 1.5 m, physical bounds | 44.74 | 5.21 | 13.93 | 743 / 718 |
-
-Against a correctly bounded 4 m model, 2 m removes 54.5% of pairs and 60.4% of overlap pairs; 71 feature tiles and 62 proof-active tiles become free. Against the v225-as-coded count model, however, physical 2 m adds 90.3% of raw pairs and leaves 34 more feature tiles and 52 more proof-active tiles. Physical 1.5 m still adds 49.8% of pairs and leaves 22 more feature tiles and 41 more proof-active tiles. So the smaller reach does **not** unlock proofs or tile skips versus the shipped source.
-
-The cause is in `BuildPassageSpatialIndices`: positions are converted to core voxels before the reach is added, but v225 adds the metre value directly. At 0.25 m per core voxel, the nominal 4.335 m bound is only 1.084 m per axis; the sweep cutoff itself remains 4 m. L129 converts the smaller physical bounds to core voxels. That makes its broadphase boxes larger than v225's, even though its actual influence cutoff is smaller. The extra segment/sample checks erase the predicted saving. The 2 m setting was selected from the pre-build counts and is the only reach fully timed.
-
-## Timing and quality
-
-Five interleaved L80 runs per W8/W12 cell were completed on a quiet machine (load 0.71, CPU idle 97.3%). L125 is the `b96dd73` source. Every near-ready cell and every whole-view cell was slower than L109 and b96dd73:
-
-| Stratum / workers | Near vs L109 / base | Whole view vs L109 / base |
-|---|---:|---:|
-| S0 W8 | +11.1% / +9.3% | +7.5% / +7.2% |
-| S0 W12 | +11.2% / +6.6% | +5.5% / +3.3% |
-| S1 W8 | +16.7% / +7.8% | +8.7% / +5.3% |
-| S1 W12 | +17.9% / +9.9% | +9.5% / +5.6% |
-| S2 W8 | +12.8% / +8.4% | +5.3% / +5.2% |
-| S2 W12 | +17.1% / +9.1% | +10.3% / +5.7% |
-| S3 W8 | +13.4% / +4.9% | +6.3% / +2.8% |
-| S3 W12 | +18.2% / +6.9% | +8.9% / +4.2% |
-
-Five UE runs at 30 m/s also missed the b96dd73 gate: near coverage 38.05% vs 40.22% (−2.17 points), far holes 4.03% vs 3.46% (+0.58 points), tick p99 11.54 vs 10.80 ms (+0.74 ms), and worst tick 14.12 vs 13.27 ms (+0.85 ms). The Linux UE host build passed after timing with `-NoUBA -MaxParallelActions=4`; Unreal was not run under `prlimit`.
-
-Fast verification passed (259 checks; 5 historical diagnostics), walkability passed at 21,425/21,425, all three passage grades stayed below 15°, and the seam audit passed 4 joins / 4,900 samples with no mismatches. Clang and GCC hashes matched for W1/W8/W12 across all three tested owner layouts (18 cases). Evaluator version 226 and three canonical owner hash baselines were added.
-
-The 23 L125 pose captures and six paired mouth close-ups are verified. All before/after PNGs are pixel-identical; these views show no visible change. The floor probe peaked at 7.9 mm, above a strict “few millimetres” reading.

+# Linux130 — passage reach
+
+On `wip/l130-reach-units` from `b96dd73`, passage influence is now **1.0533 m**: 0.75 m shell + 0.21 m relief + 0.50 m smooth-max support (`width/6`) + 0.01 m margin. One metres-to-core-voxels conversion feeds proof, feature, fallback and off-grid bounds; the sweep cutoff uses the same metre value. The dead 4 m cutoff is removed. Evaluator version is 227.
+
+The debug shell/crest audit sampled 25,728 points, including 5 mm inside and outside the reach; 18,993 had sign-relevant passage contribution. Proof and feature bounds missed none. The nine-station floor probe still peaks at **7.884 mm**, matching L125. The 23 L125 views and six L129 mouth close-ups are byte-identical. Fast verification, walkability and shell audits pass; the seam audit found 0 mismatches across 4 pairs / 4,900 shared samples.
+
+Clang/GCC W1/W8/W12 hashes agree across all 18 runs. Versus v225, hashes changed for owner4 full-detail, whole-view and LOD0–3; owner2 surface-world and floating-islands whole-view and LOD2–3. Exact-query hashes stayed unchanged. The v227 canonical baselines are recorded; changed hashes reflect the shorter density influence halo, while sampled sign-relevant bounds and captured surfaces remain covered.
+
+L80 timing used 10 interleaved pairs per stratum/worker count. Across the eight case medians, the weighted deltas were +0.33% for LOD0–2 and +0.31% whole-view. Across 80 paired runs, mean deltas were +0.26% (95% interval −0.44% to +0.96%) and +0.47% (−0.06% to +1.00%); both intervals include zero. No measurable timing change; UE movement was skipped. The Linux UE host build succeeded in 76.30 s with `-NoUBA -MaxParallelActions=4`, without `prlimit`. `ARCHITECTURE.md` and `CODEMAP.md` had no note for this optimized influence reach, so they were unchanged.

+# Linux131 — current state and dead experiment cleanup
+
+Branch `wip/l131-current-state`, based on `cbbfd46`; Core evaluator remains v227. The root [`CURRENT-STATE.md`](../../../../CURRENT-STATE.md) consolidates the shipping behavior, current references, verification commands, open gaps, and closed proposals.
+
+## Removed
+
+- Removed `VOXELFORGE_L86_DISABLE_PASSAGE_COMPOSITION`, `VOXELFORGE_L88_DISABLE_PASSAGES`, `VOXELFORGE_L88_DISABLE_BOUNDARY_BANDS`, and `VOXELFORGE_L88_ALLOW_PASSAGE_ABLATION_WALKABILITY_FAILURE`. These only supported archived passage/boundary ablations in `Linux86/RunL86Ceiling.py`, `Linux87/RunL87Timeline.py`, and `Linux88/RunL88CeilingSplit.py`; no current `verify.py` gate or live comparison uses them. Passage feature selection, passage composition, and boundary bands now run on the normal path, and passage-route validation cannot be waived by the old ablation flag.
+- Removed the `VOXELFORGE_AUDIT_LEGACY_ROUTE_GRADE` block from `Standalone/Source/WorldAssemblyPrototype.h`. The source contained its only reference; no test, current tool, or report invoked it.
+- Kept route-candidate grading and all user-visible behavior. This cleanup adds no evaluator version or baseline change.
+
+## Switch and hook inventory
+
+### Environment switches in compiled Core/Source
+
+| Switch | Effect and consumer | Keep decision |
+|---|---|---|
+| `VOXELFORGE_L74_TIGHT_PROOF_CONTROL` | Proof negative control. `Linux74/FalsifierL74.py` and `Linux75/FalsifierL75.py`. | Keep for falsifier reproducibility; not a current fast-tier input. |
+| `VOXELFORGE_L75_TN_BLOCK_REGRESSION` | Fixed TunnelNetwork regression path in Core and mesher. `RunTnBlockRegressionL75.py` and `FalsifierL75.py`. | Keep; the regression tools still consume it. |
+| `VOXELFORGE_L98_PASSAGE_PREP_TRACE` | Emits preparation-stage timing/count data. `RunL98Hashes.py` and `RunL98ReuseCounts.py`. | Keep as a focused profiler for future preparation comparisons. |
+| `VOXELFORGE_L98_PASSAGE_REUSE_PROBE` | Compares the prepared projection with direct scalar queries. `RunL98ReuseCounts.py`. | Keep for exactness probes. |
+| `VOXELFORGE_L104_FAR_HIT_CACHE` | Selects indexed versus linear far-hit candidate lookup. `RunL104ReadinessPairs.py` and `RunL104ProbeStats.py`. | Keep for reproducible A/B comparisons; cache defaults on. |
+| `VOXELFORGE_L104_FAR_HIT_STATS` | Emits far-hit candidate/query counters. `RunL104ProbeStats.py`. | Keep for the measurement tool. |
+| `VOXELFORGE_L115_DENSITY_PROFILE` | Enables density and floor-query profiling. `RunL115DensityProbe.py`, `RunL119DensityProbe.py`, and `RunL125DensityProbe.py`. | Keep; these remain the focused floor-probe path. |
+| `VOXELFORGE_L130_PASSAGE_REACH_PROOF_AUDIT` | Checks passage proof/feature influence bounds. L130's reach audit and report. | Keep for reach changes and audit reproduction. |
+
+Archived runners also set `VOXELFORGE_L81_PASSAGE_BOUND_PADDING_VOXELS`, `VOXELFORGE_L86_PASSAGE_RESULT_CACHE`, `VOXELFORGE_L90_PASSAGE_BRICK_METRES`, `VOXELFORGE_L90_PASSAGE_CANDIDATE_CENSUS`, `VOXELFORGE_L90_PASSAGE_REACH_METRES`, `VOXELFORGE_L91_PASSAGE_SOURCE_FLOOR_VOXELS`, `VOXELFORGE_L93_PASSAGE_CARVE_REACH_METRES`, `VOXELFORGE_L98_PASSAGE_REUSE_COUNTS`, `VOXELFORGE_L114_DENSITY_PROFILE`, and `VOXELFORGE_L118_TAG_TIMING`. None has a compiled-source reader at `cbbfd46`; they are inert historical runner strings.
+
+### Other experiments, diagnostics, and legacy paths retained
+
+- **World-changing tunnel ablations:** all 14 `voxel.TunnelAblate*` controls remain (`CaveWarp`, `DetailOps`, `RoomSDF`, `TunnelSDF`, `TunnelCore`, `PassageCarving`, `PassageStructuralPosts`, `NativeFloor`, `Disturbances`, `OriginSpine`, `BoundarySeal`, `LandingPosts`, `XYEdgeSeal`, `PitChimneySDF`). The editor commandlet writes their resolved mask into export and result manifests; the archived `PERF-SAMPLED.md` and `WORK-NEXT.md` record their measurements. No current runner invokes an ablation. Keep for manifest attribution and historical reproduction; removing it needs a metadata migration. Source: [`VoxelDensityAblation.cpp`](../../../../Source/VoxelForge/Private/VoxelDensityAblation.cpp), [`VoxelForgeExploreCommandlet.cpp`](../../../../Source/VoxelForgeEditor/Private/VoxelForgeExploreCommandlet.cpp).
+- **Research fields:** `voxel.ResearchRedefinedDensityField`, `voxel.ResearchRedefinedDensityDetailScale`, `voxel.ResearchParameterizedCave`, and `voxel.ResearchParameterizedCaveSet` are default-off and used by `Tools/VoxelForgeTest.ps1` steps 2d/2e/2f. The region-eval commandlet consumes `SetResearchBrickBinningEnabled`, `SetResearchBrickRoomReachScale`, and `SetResearchRegionCacheWindowEnabled`; keep these editor-only experiment paths. Source: [`VoxelForgeRegionEvalExperiment.cpp`](../../../../Source/VoxelForgeEditor/Private/VoxelForgeRegionEvalExperiment.cpp), [`VoxelForgeTest.ps1`](../../../../Tools/VoxelForgeTest.ps1).
+- **Runtime profiling and trace:** `voxel.SampleStacks` still starts `FVoxelStackSampler` (the guarded `Tools/VoxelForgeTest.ps1 -SampleDensityStacks` path consumes it); `voxel.ProfileDensity`, `voxel.ProfileDensityFull`, `voxel.ProfileTileGeneration`, `voxel.ProfileCollisionCookStages`, and `voxel.PerfAttribution` remain opt-in. `voxel.StartupTraceFile`, `voxel.StartupTraceMaxTiles`, and `voxel.StartupTraceUntilEndPlay` feed the Unreal startup trace used by the arrival/movement runners. Keep. Build-time `VOXELFORGE_PROFILE_LEGACY_TERMS` (L76) and `VOXELFORGE_PROFILE_L77`/`--linux77-profile` (stack sampler and route census) remain in `Standalone/BuildLinux.sh` and Core.
+- **Standalone profiles and timelines:** retained `--profile-column-overlap`, `--profile-lod-work`, `--profile-passage-composer`, `--instrument-tile-drain`, `--cold-worker-timeline`, `--linux77-profile`, `--tls-probe=N`, `--tls-probe-touch=...`, and `--diagnostic-slow-shape-compile-ms=N`. The viewer's `--profile-attribution`, `--profile-detail-band`, and `--profile-far-column-overlap` remain. The L77 profiler, tile drain instrumentation, timelines, and TLS probe are measurement hooks; archived reports and runners still provide reproducible consumers.
+- **Standalone audits:** all source-advertised hooks remain: `--audit-ore-vein-yield`, `--audit-resolved-layout-boundaries`, `--audit-strate-transitions`, `--audit-resolved-layout-passages`, `--audit-heightfield-profile`, `--audit-motif-intervals`, `--audit-landmark-reachability`, `--audit-native-caves`, `--audit-native-lattice`, `--audit-surface-clearance`, `--audit-uniform-block-proofs`, `--audit-base-page-equivalence`, `--audit-route-parity`, `--audit-passage-tile-seams`, `--audit-passage-source-clamp`, `--audit-passage-carve-reach`, `--audit-tile-shape-readiness`, and the mesher's `--audit-raw-skirts`. `verify.py fast` consumes the current route, passage, block-proof, transition, native-field and negative-control subset; dedicated L37/L75/L125/L130 runners exercise the specialized audits. Keep the whole audit set.
+- **Evaluator A/B controls:** `voxel.FastIsFinite`, `voxel.UseFusedEvaluator`, `voxel.WormBlockSkip`, `voxel.TileCacheWindow` / its two minimum-LOD controls, `voxel.SpatialIndex`, `voxel.ChunkRoutingCache`, `voxel.UseOperatorBlock`, `voxel.CoreColumnCacheDirectMapped`, `voxel.CoreMCGradientMemoization`, `voxel.FloorRound1PassageProjectionCache`, `voxel.PlayerFitMemo`, `voxel.UseBlockEarlyOut`, `voxel.OuterClassifierMode`, and `voxel.SealedSolidProof` remain. They select optimized or comparison paths; the density block equivalence test explicitly forces `UseFusedEvaluator=0`, while most others are production defaults or historical measurement controls. `voxel.WormsForceOff` is a world-changing development measurement override. Kept; no current L131 gate changes them.
+- **Standalone A/B and geometry controls:** `--exact-midpoint-density-memo`, `--no-exact-midpoint-density-memo`, `--active-lane-batching`, `--proof-block-cells=N`, `--parallel-sign-edge-repair`, `--serial-sign-edge-repair`, and `--shape-helper-limit=8|12` remain. The L94 report documents serial edge repair; no current `verify.py` consumer was found for the other CLI A/B controls, so they remain pending a separately reviewed removal. `voxel.TilePostReachDebug`, `voxel.TilePostReachScale`, and `voxel.TileReachCostDiagnostics` remain for the tile-post-reach test; `voxel.TunnelMouthTrim` remains a development-only room-mouth geometry control. No L131 gate uses these.
+- `FLegacyGeneratorFieldAdapter` remains the Core fallback for unsupported generator/recipe combinations, and Unreal's Core switch remains default-off. `voxel.StreamingLegacyPendingResultCap=1` remains the L120–L123 admission negative control; `voxel.StreamingCoarseFirst` remains opt-in pending a rendered owner-plan check. `bStandaloneResearchRoundTunnels` and `bStandaloneResearchEnhancedWalls` remain consumed by the standalone viewer/Core adapter.
+
+## Checks
+
+- Clang 19 and GCC standalone builds passed with the L131 source stamp `5119cee164406856cbca496d160c0e0a8124ae2529fa7c0ebd51634a7c65a6cb`. `Standalone/BuildLinux.sh` applied the required CPU and address-space limits.
+- L80 timing: one warm-up per binary and five interleaved pairs in each of four strata × W8/W12 cells, comparing the pre-cleanup L130 binary with L131. Load was 0.81; CPU idle was 99.2%. Across 40 pairs per metric, mean relative change was −0.22% near-ready (95% CI −1.02% to +0.57%) and −0.29% whole-view (−1.04% to +0.46%); the intervals include zero. [Raw timing summary](../../../../Saved/Linux/l131/timing/summary.json).
+- Exact hashes: **24/24** owner4 SW/FI/TN/VS × Clang/GCC × W1/W8/W12 tile and whole-view identities; **18/18** canonical cases across owner4 SurfaceWorld and owner2 SurfaceWorld/FloatingIslands. All match the pre-cleanup L130 binary and agree across compiler/worker combinations. For transparency, forcing the owner4 dataset through `--recipe=floating-islands` exited during setup with “could not find a finite SurfaceWorld strate”, before hashing; it is not a valid canonical case. [Tile matrix](../../../../Saved/Linux/l131/hash-matrix/summary.json), [canonical matrix](../../../../Saved/Linux/l131/canonical-matrix/summary.json).
+- Walkability: **21,425/21,425** passage centerline samples open. Seam audit: **4 pairs / 4,900** shared samples, zero mismatches. [Audit log](../../../../Saved/Linux/l131/seam-audit.log).
+- Fast tier: **PASS**, 259 gated checks plus 5 diagnostics, 80 runs, 371.0 s. The five diagnostic-only comparisons are historical baselines; all required checks pass. [Summary](../../../../Saved/Linux/l131/fast-summary.json).
+- Linux `VFHostEditor`: **PASS**, 27/27 actions, 78.81 s with `-NoUBA -MaxParallelActions=4`, no `prlimit`. UBT's default log rotation first failed before compilation in the read-only user config directory; the successful rerun set `-Log=.../Saved/Linux/l131/ubt.log`. Three existing RealtimeMesh deprecation warnings remain. [Build log](../../../../Saved/Linux/l131/ue-build.log).
+- Unreal `Source/` files changed: **none**. No Windows compile is requested by this diff; Windows determinism remains unverified.
+- `git diff --check` passes. No commit, push, or stash was made.
+
+Builds, per-run logs, timing records, hash records, and audit output are under `Saved/Linux/l131/`.

+# L132 — owner density dispatch
+
+## Result
+
+With Core enabled in the owner headless pipeline, the four strates bind to four paths. Unreal’s `bUseVoxelForgeCore` remains opt-in and defaults off. The fast-tier diagnostic reports the Core bindings at the four L80 owner poses and attributes hashed tiles by tile-center height within the resolved stratum bounds.
+
+| Strate | Owner recipe | Bound path | Tile centers / share |
+|---|---|---|---:|
+| SW (0) | `SurfaceWorld.Heightfield2D` v2 | `SurfaceWorld-native` | 2,640 / 100% |
+| FI (1) | `FloatingIslands.ClusterField` v0 | `compiled-analytic/FloatingIslands` | 2,128 / 100% |
+| TN (2) | `legacy.TunnelNetwork` v0 | `compiled-analytic/TunnelNetwork` | 2,208 / 100% |
+| VS (3) | `legacy.VerticalShafts` v0 | `compiled-analytic/VerticalShafts` | 1,392 / 100% |
+
+SW has a matching strate/bounds `SurfaceWorld` plan, and its `Heightfield2D` evaluator is valid. FI has a legacy v0 layout record but no matching `FloatingIslandPlan`, so `FloatingIslandFieldV1` cannot bind. The Core owner manifest has zero island plans. TN and VS have legacy recipe IDs, not `Core.Caves.PrimitiveField` v1 or `Core.Lattice.PrimitiveField` v1. Their resolved layouts therefore lack the matching graph recipe and native-field capability. All three fall through to `FLegacyGeneratorFieldAdapter`.
+
+The dispatch check is in the fast tier and can also be requested from the headless binary with `--density-dispatch-report`. It prints the per-strate bound adapter/path and hashed tile-center path shares. Its tile counts aggregate the four standard owner poses; tiles whose centers fall outside an interior interval are excluded, and a tile spanning a boundary is assigned by its center. Per-view logs are `Saved/Linux/l132/owner-density-dispatch-s*-clang.log`; the printed shares are in `Saved/Linux/l132/logs/verify-fast.log` and `Saved/Linux/l132/fast-summary.json`.
+
+Across the 8,368 classified tile centers, path shares are 31.5% SurfaceWorld-native, 25.4% compiled-analytic/FloatingIslands, 26.4% compiled-analytic/TunnelNetwork, and 16.6% compiled-analytic/VerticalShafts.
+
+## Native FI decision
+
+The native evaluator is present. `BuildFloatingIslandStratumPlan` can convert the owner’s legacy island parameters to a v8 plan, but the owner’s imported manifest does not contain that plan. The existing automatic-plan branch is guarded by `bImportedOverride` inside the generated-assembly branch, so it does not fill this owner’s missing imported plan.
+
+I built a candidate v8 plan for the existing owner FI strate without changing the default owner data. Its raw island-route audit passed: 29 route points, 78,336 capsule samples, zero blocked samples, zero unsupported probes, and zero grade failures. The composed owner audit did not pass:
+
+- Existing compiled-analytic owner: all 3 passage interfaces pass; shell floor violations 0; ripple checks 3/3.
+- Native FI candidate: only 2/3 interfaces pass; the added FI route is not walkable (1/2 strate routes walkable); shell floor violations 13; ripple checks 2/3.
+- Passage tile seams passed for both bindings: 4 pairs, 4,900 shared samples, zero mismatches.
+
+Native FI is a quality regression on the owner’s current passages, despite its standalone route plan passing. I did not switch the owner. The conditional captures, W8/W12 timing matrix, and Clang/GCC W1/W8/W12 matrix were not run because the candidate failed the composed walk/shell gate. No Core version or output baseline changed; the default owner output remains on its existing bindings. No Linux UE host build was run because there was no qualifying native change or timing matrix.
+
+## TN/VS graph translation size
+
+The active TN `GenerationParams` block has 47 fields; VS `VerticalShaftParams` has 11. Each also has 15 passage settings. Both have `CoreGeometry.GeneratorRecipe=0` and empty `Rooms`, `Tunnels`, and `Stamps` arrays. Native cave/lattice authoring requires at least one explicit room and one edge, with geometry, links, and route data. There is no adapter translating those legacy generator blocks into graph records. This is a substantial procedural migration, not a small recipe mapping, so I did not build it this round.
+
+## Verification
+

+# VoxelForge — research R46 (read-only): generator capability matrix
+
+You are a researcher. **Read only: do not edit, create or delete any file, and do not build, run or test anything.**
+Read the code, reports and design docs. Be thorough: verify each claim by hand in the code, and mark each one
+[CODE] file:line, [MEASURED] report, or [INFERENCE]. Branch `assembler/world` (`cbbfd46`).
+
+## Why
+
+The owner approved the next focus (from `Standalone/Research/WorldAssemblerM3/Astra4/REVIEW.md` #3): turn generator
+breadth into playable variety. First we need an honest picture of what each strate/generator family can do today.
+
+## Task
+
+Find every generator family / strate type: surface world, floating islands, caves/cavern, tunnel network, vertical
+shafts, dreamcore/liminal, and any others in the code (Core native, legacy fallback, op stack, composer). For each,
+fill one row:
+- **Core path:** native Core evaluator, legacy fallback, or not in Core at all? Where is it dispatched?
+- **Entrances/exits:** arrival and departure mouths, and the primordial law (arrival → departure walkable).
+- **Interior connectivity:** walkable, and audited by what?
+- **Edits:** does digging (diff layer) work on it in the Core path?
+- **Materials/content:** material IDs, decorations, foliage, lights, anything placeable.
+- **Far terrain:** does it have far LOD/shells?
+- **Performance:** latest measured near-ready, with the report.
+- **Identity:** what makes it look and feel distinct today; is it recognisable without a label?
+- **Owner world:** used in `Standalone/data/owner_world.json`? Which strate letter (SW/FI/TN/VS)?
+- **Gaps:** what's missing for it to be a "place" with its own identity and a destination.
+
+Then:
+1. Which three families are closest to being distinct places (the owner's example: a grounded cave, an island
+   environment, one liminal identity)? What is the smallest work to get each there?
+2. What does the composer (`VoxelSeasonManifest.cpp`, `COMPOSER-NOTES.md`) already do for tagged content, and what's
+   the smallest next step?
+3. Risks: places where the Core path silently falls back, or where a family exists in docs but not in code.
+
+Write plain Markdown: the matrix plus ≤ ~800 words of findings.

+
+Read-only review of `assembler/world` at `cbbfd46`; no files changed, and no builds, runs, or tests were performed.
+
+## Shared dispatch and contracts
+
+[CODE] The eight `ECaveGeneratorType` values are TunnelNetwork, FlatPlain, CrystalChamber, Maze, SurfaceWorld, VerticalShafts, FloatingIslands, and Underwater. `NativeCaves`, `NativeLattice`, and `ProfiledHeightfield` are optional Core recipes layered onto those types, not additional strate types. [VoxelStrateTypes.h:175](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:175>) [VoxelStrateTypes.h:203](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:203>)
+
+[CODE] Core binds native SurfaceWorld and FloatingIslands evaluators when matching plans exist; it binds native cave/lattice graph fields when their capabilities are present. Otherwise it attaches a legacy generator adapter. The density dispatcher exposes paths such as `SurfaceWorld-native`, `SurfaceWorld-legacy`, `Caves-native`, and `compiled-analytic/<kind>`. [ShapeWorldInternal.h:600](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:600>) [ShapeWorldInternal.h:640](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:640>) [ShapeWorldInternal.h:649](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:649>) [ShapeWorldInternal.h:3101](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3101>)
+
+[CODE] The adapter plans inter-strate passages and resolves the layout before Core evaluates it. The composer’s primordial law checks a player-fit, walk-only path between the center-column interior endpoints; it is an arrival-to-departure test, not a requirement that every disconnected room or shaft join the largest component. [VoxelForgeCoreAdapter.cpp:1545](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelForgeCoreAdapter.cpp:1545>) [VoxelSeasonManifest.cpp:2194](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelSeasonManifest.cpp:2194>) [VoxelStrateMeasure.h:315](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateMeasure.h:315>)
+
+[CODE] Core edit transactions become density brushes applied after field composition. The same stage covers native and fallback density paths. [VoxelForgeCore.cpp:3307](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:3307>) [ShapeWorldInternal.h:3036](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:3036>) [ShapeWorldInternal.h:5201](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:5201>)
+
+[CODE] Any strate can author decorations, landmarks, ambient actors, and creatures. Placement supports actors or instanced meshes; Core material samples default to host ID 1 and can carry two resource IDs. These are shared content hooks, not a distinct palette per generator family. [VoxelStrateDefinition.h:352](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateDefinition.h:352>) [VoxelStrateTypes.h:2204](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:2204>) [VoxelForgeCore.h:1273](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h:1273>)
+
+**Performance key:** L125 is the latest absolute owner four-strata LOD0–2 timing table I found; L130’s paired comparison found no measurable change. L125 labels rows S0–S3, so mapping them to SW/FI/TN/VS in the explicit L109 order is an **[INFERENCE]**. Values below are W8/W12 medians in seconds; they measure the owner layout, not isolated native evaluator costs.

+## Matrix
+
+| Family / owner | Core path | Entrances, connectivity, and primordial law | Edits, materials, and content | Far terrain and performance | Identity and gaps |
+|---|---|---|---|---|---|
+| **SurfaceWorld — SW** | [CODE] Native `Heightfield2D` when a matching surface plan binds; legacy SurfaceWorld fallback otherwise. [ShapeWorldInternal.h:600](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:600>) [ShapeWorldInternal.h:6685](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:6685>) | [CODE] Owner export enables an open surface entry; SW also supplies the 0–1 departure mouth. [MEASURED] The shared route audit passed 21,425/21,425 centerline samples. [owner_world.json:1](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/data/owner_world.json:1>) [L125:39](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux125/REPORT.md:39>) | [CODE] Digging works. Surface supports biome terrain/material signals, water, and the shared placement hooks; no family-specific content pack is proven in the owner export. [VoxelStrateTypes.h:1609](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:1609>) | [CODE] Common mesh LOD and far shells; native surface plans also get far ground/cap refinement. [MEASURED] **SW:** 0.780/0.807 near-ready. [VoxelForgeCore.cpp:2996](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:2996>) [VoxelForgeCore.cpp:3073](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/VoxelForgeCore.cpp:3073>) | [INFERENCE] Outdoor hills, mountains, rivers, and beaches have a legible silhouette. It still needs distinctive foliage/materials, sound, and a destination to read as a complete place. |
+| **FloatingIslands — FI** | [CODE] Native island field when a matching island plan binds; otherwise falls through to the legacy analytic path. [ShapeWorldInternal.h:620](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:620>) [ShapeWorldInternal.h:6692](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:6692>) | [CODE] Owner route enters from SW and departs toward TN; native island route audits check capsule clearance and support. [MEASURED] The owner passage checks passed. [MEASURED] L67 reported the owner FI path as `compiled-analytic/FloatingIslands`, not native; the reason was unresolved in R36. [L67:5](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux67/REPORT.md:5>) [Research36:11](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Research36/REPORT.md:11>) | [CODE] Digging works; foliage, landmarks, ambient actors, and lights can use shared placement systems. [INFERENCE] No island-specific owner palette/content is established by the export. | [CODE] Common far mesh and shell paths. [MEASURED] **FI:** 0.981/0.962 near-ready in the owner layout. | [INFERENCE] Floating land silhouettes can be immediately recognizable. Confirm native dispatch, then add an island ecology, a landmark, and a clear route/destination. |
+| **TunnelNetwork — TN** | [CODE] The owner’s regular path is Core’s legacy/compiled-analytic fallback. `NativeCaves` is optional for TN/Underwater and evaluates authored room/tunnel graphs. [VoxelForgeCoreAdapter.cpp:145](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelForgeCoreAdapter.cpp:145>) [VoxelGenerator.cpp:2645](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2645>) | [CODE] Owner arrival from FI and departure toward VS. [MEASURED] Inter-strate walkability passes; that does not prove every interior room is connected. Native cave fixture flood-fill connected its chosen arrival/departure pair. [L54:21](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux54/REPORT.md:21>) | [CODE] Digging works. Generic cave decorations/landmarks/lighting are available; there is no family-specific Core material palette. | [CODE] Common far LOD/shells. [MEASURED] **TN:** 1.025/0.965 near-ready in the owner layout. Optional native-cave fixture: 0.177 s near ring and 0.706 s cold whole view, a different workload. [L54:37](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux54/REPORT.md:37>) | [INFERENCE] Rooms and tunnels read as caves, but the owner route lacks a content-defined destination. Small cave graph and a landmark/content pack would make it a place; translating the owner’s legacy parameters to native cave records remains separate work. |
+| **FlatPlain** | [CODE] Legacy fallback/op stack only; it uses the slab builder. [VoxelGenerator.cpp:2600](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2600>) [VoxelDensityOpStack.cpp:9373](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelDensityOpStack.cpp:9373>) | [CODE] No intrinsic mouths; shared passage planner supplies endpoints. [INFERENCE] Its open floor/ceiling band may connect the selected endpoints, but no family-specific arrival/departure audit was found. | [CODE] Digging works; shared decorations/landmarks can populate the chamber. | [CODE] Common far LOD/shells. [MEASURED] No separate near-ready timing found. | [INFERENCE] Open underground plain with columns. Needs a distinctive floor/ceiling profile, content, and destination; it has no native Core slab recipe. |
+| **CrystalChamber** | [CODE] Same slab op-stack builder as FlatPlain; distinctness comes from parameter values, especially ceiling roughness. [VoxelGenerator.cpp:2600](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2600>) | [CODE] Same shared-mouth arrangement as FlatPlain; no family-specific walk audit found. | [CODE] Digging works. Crystal decoration is authorable through shared placement, not guaranteed by the geometry type. [VoxelStrateTypes.h:169](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:169>) | [CODE] Common far LOD/shells. [MEASURED] No separate near-ready timing found. | [INFERENCE] Hanging formations could distinguish it, but parameters alone do not supply crystal materials, lighting, or a destination. |
+| **Maze** | [CODE] Legacy maze op stack; optional `NativeLattice` graph recipe, which is shared with VerticalShafts rather than a dedicated native maze generator. [VoxelForgeCoreAdapter.cpp:159](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelForgeCoreAdapter.cpp:159>) [VoxelGenerator.cpp:2592](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2592>) | [CODE] Mouths are shared-planner endpoints; native lattice fixtures test capsule reachability between chosen endpoints. [MEASURED] L60 native lattice fixture: 0.561 s near ring, 1.701 s whole view—not the owner near-ready workload. [L60:19](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux60/REPORT.md:19>) [L60:36](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux60/REPORT.md:36>) | [CODE] Digging works; common content hooks apply. | [CODE] Common far LOD/shells; L60 streamed the lattice fixture through LOD0–8. [L60:15](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux60/REPORT.md:15>) | [INFERENCE] Tight branching corridors are a recognizable grammar, but the native fixture’s helix/maze graph needs a content destination and stronger per-seed identity. |
+| **VerticalShafts — VS** | [CODE] Legacy shaft op stack; optional `NativeLattice` is a generic authored graph, not a shaft-specific Core evaluator. [VoxelGenerator.cpp:2622](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2622>) | [CODE] Owner arrival comes from TN; the four-strata export has no lower fifth-stratum passage. [MEASURED] The composer found a VerticalShafts arrival/departure violation; L58’s lattice route passed but was a helix. [COMPOSER-NOTES.md:1437](</home/jahni/VoxelM/Plugins/VoxelForge/COMPOSER-NOTES.md:1437>) [Linux58:11](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux58/REPORT.md:11>) | [CODE] Digging works; generic props and lights can be placed. | [CODE] Common far LOD/shells. [MEASURED] **VS:** 0.879/0.838 near-ready in owner layout. | [INFERENCE] Vertical silhouettes could distinguish it, but the native graph example is not an open shaft. Needs a shaft-specific core, safe landings, and a proven route. |
+| **Underwater** | [CODE] TunnelNetwork density plus water behavior; optional NativeCaves recipe is accepted. No separate native water generator recipe. [VoxelGenerator.cpp:2638](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelGenerator.cpp:2638>) [Unreal1:131](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Unreal1/REPORT.md:131>) | [CODE] Shared passage mouths; composer’s law is walk-only, so it does not certify swimming or water traversal. [INFERENCE] A flooded route needs dry walkable sections or a separate traversal rule. | [CODE] Digging works; water and shared content are available, but the native assembly recipe does not itself provide an authored water feature. | [CODE] Common far terrain; far water presentation is not established here. [MEASURED] No separate near-ready timing found. | [INFERENCE] “Flooded cave” is a plausible identity, but water, lighting, air pockets, and destination spaces need authored treatment. |
+| **Dreamcore / liminal** | [CODE] No `Dreamcore` generator type. Existing Core stamps/motif fields are overlays; motif override currently requires a resolved SurfaceWorld strate. [VoxelStrateTypes.h:175](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:175>) [WorldAssemblyPrototype.h:568](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Source/WorldAssemblyPrototype.h:568>) | [CODE] Inherits mouths and connectivity from its base family; motif fixtures preserve route keepouts. [MEASURED] L60 motif overlay: 0.493 s near ring, 1.326 s whole view. [Linux56:21](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux56/REPORT.md:21>) [L60:35](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux60/REPORT.md:35>) | [CODE] Digging applies to the composed field; current motif kinds include carve arch/ellipsoid and fill pillar/dais/monolith/platform. [VoxelStrateTypes.h:222](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateTypes.h:222>) | [CODE] Base field uses common far LOD/shells. Motifs have LOD coverage, but no liminal-specific far treatment. | [INFERENCE] Motifs alone do not read as dreamcore. It needs a repeated spatial grammar, coherent palette/light/sound, and an explorable destination. Not in owner world. |
+
+Owner mapping: [MEASURED] the owner export references four fixed strata and opens the surface; the named four-family owner route is SW/FI/TN/VS. [CODE] The L125–L130 timings are for that owner layout. [owner_world.json:1](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/data/owner_world.json:1>) [L109:21](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux109/REPORT.md:21>) [L120:23](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux120/REPORT.md:23>)
+
+## Findings
+
+1. **Closest to distinct places: TN caves, FI, and liminal overlays.** [INFERENCE] TN already has cave geometry and route proof: add one authored destination chamber plus a small landmark/material/light kit. FI already has a distinctive suspended-land silhouette and route support: first confirm its native dispatch, then add foliage, a landmark, and route cues. Liminal is the smallest overlay slice: reuse the flat/profiled base and existing monolith/platform stamps, then define one repeatable anomaly pattern and a matching content kit. These need authored destinations and themes more than new density families.
+
+2. **Composer status and smallest next step.** [CODE] `VoxelSeasonManifest.cpp` rolls candidates from a corpus, measures them, rejects vacuous/fragmented/primordial-law failures, and selects for grounded/outlier mix plus archetype/recipe variety. Promoted records carry an archetype tag and corpus provenance is tagged `project`, `default`, or `promoted`. [VoxelSeasonManifest.cpp:2523](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Private/VoxelSeasonManifest.cpp:2523>) [COMPOSER-NOTES.md:431](</home/jahni/VoxelM/Plugins/VoxelForge/COMPOSER-NOTES.md:431>) [COMPOSER-NOTES.md:1466](</home/jahni/VoxelM/Plugins/VoxelForge/COMPOSER-NOTES.md:1466>) Strate and biome gameplay tags are stored, but theme draws for materials, creatures, decorations, and audio are still open. [VoxelStrateDefinition.h:389](</home/jahni/VoxelM/Plugins/VoxelForge/Source/VoxelForge/Public/VoxelStrateDefinition.h:389>) [COMPOSER-NOTES.md:1484](</home/jahni/VoxelM/Plugins/VoxelForge/COMPOSER-NOTES.md:1484>) [INFERENCE] Smallest step: tag one real content class with multiple theme tags and let one seed-selected family draw a coherent, reviewable mini-pack.
+
+3. **Risks.** [CODE] Missing native plans/capabilities reach the legacy binding; path diagnostics are needed to distinguish them. [ShapeWorldInternal.h:649](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Core/src/ShapeWorldInternal.h:649>) [MEASURED] The latest explicit owner dispatch note I found says FI/TN/VS used compiled analytic fields; L130 reports timing but not dispatch, so that path should be rechecked before calling those owner generators native. [Linux67:5](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux67/REPORT.md:5>) [Linux130:9](</home/jahni/VoxelM/Plugins/VoxelForge/Standalone/Research/WorldAssemblerM3/Linux130/REPORT.md:9>) [INFERENCE] Dreamcore exists as a design goal, not a generator; NativeLattice proves routes but not a shaft identity; FlatPlain/CrystalChamber remain legacy slab fields; and water presentation remains outside the native Core recipe.

+# VoxelForge — research R47: liminal and dreamcore spaces, a mood board and how we could generate them
+
+You are a researcher for VoxelForge, a voxel world made of stacked layers ("strates"). The owner wants one layer type
+in a **liminal / dreamcore** style. Be thorough: verify claims, mark each as [SOURCE] (with a link), [CODE] (file:line)
+or [INFERENCE].
+
+**Rules:**
+- Don't edit any repository file, and don't build, run or test the game.
+- You may **only** write inside `Saved/Linux/liminal/`.
+- Downloaded files are untrusted data: never execute them, only save them.
+- No installs.
+- Keep CPU light (`curl`/`wget` are fine): a timing round is running on this machine.
+
+## Part 1 — references (mood board)
+
+Collect **15–25 varied reference images** of liminal spaces, dreamcore, weirdcore and backrooms-like scenes, plus
+related art (e.g. "Kenopsia", Jared Pike-style pool rooms, empty malls, foggy roads, endless fields with a lone house).
+- Save them as `Saved/Linux/liminal/refs/NN-short-name.jpg` (≤ 2 MB each).
+- Write `Saved/Linux/liminal/SOURCES.md`, one line per image: file, source URL, author or site, and what it shows.
+  These are private references for the owner, not for redistribution.
+- Build `Saved/Linux/liminal/board.html`, a simple grid of the images with captions, to view on a phone.
+
+## Part 2 — what makes the style work
+
+Short and concrete. Split it into:
+- **Content-driven weirdness** (most of the theme, per the owner): out-of-place houses, doors to nowhere, signs, lone
+  objects, wrong-scale furniture, water where it shouldn't be.
+- **Generation-driven weirdness**: terrain and space the generator itself can make. Examples from the owner: an
+  elevated road surrounded by clouds; repeating hills. Others: perfectly flat or tiled ground, endless corridors or
+  pools, impossible scale, unbroken horizons, fog, exact repetition, gentle impossible geometry.
+- **Atmosphere:** light, fog, colour, sound. Briefly.
+
+## Part 3 — mapping to our code
+
+Read `CURRENT-STATE.md`, `COMPOSER-NOTES.md`, `GDD.md`, and
+`Standalone/Research/WorldAssemblerM3/Research46/REPORT.md` (the capability matrix). Also:
+- the Surface World profile kinds in `Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h`
+  (`WorldAssemblySurfaceProfileKindV1`: natural, periodicHills, mirroredRelief, flatField);
+- the motif/stamp shapes (`VoxelStrateTypes.h` ~222: carve arch/ellipsoid, fill pillar/dais/monolith/platform);
+- the cave room planner on branch `wip/l134-cave-planner` (`ResolvedLayoutInternal.h`, `makeCompound`).
+
+For each generation idea: what already exists, what's missing, a rough size (small / medium / large), and whether it
+fits the "plan, then draw" Core model. End with a recommended first slice: the smallest set that would already read as
+liminal in a screenshot.
+
+Write `Saved/Linux/liminal/REPORT.md` (≤ ~1,200 words) and print a short summary at the end.

+# VoxelForge R47 — liminal / dreamcore
+
+## Result
+
+[INFERENCE] Start with a rare, content-led anomaly on a flat SurfaceWorld: one ordinary, recognizable object placed where it makes no sense, framed by a quiet empty field and mild horizon fog. This can read in a screenshot without a new generator family.
+
+[CODE] The requested references describe different snapshots: `CURRENT-STATE.md` labels the tree L132/Core v227 (`CURRENT-STATE.md:3,7`), while the live Core header says evaluator v236 (`Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h:513`). R46 calls itself a review of an earlier `assembler/world` snapshot (`Standalone/Research/WorldAssemblerM3/Research46/REPORT.md:3`). The mapping below follows the live source; R46 is historical context.
+
+## 1. What makes it work
+
+- **Content-driven weirdness (the main signal).** [INFERENCE] Keep most geometry ordinary, then break one semantic expectation: a lone house in an indoor hall; a door standing in a field; a sign that points nowhere; a child-sized chair in a huge room; or still pool water in a dry corridor. Repeat one object exactly or vary its scale to make the wrongness legible. [SOURCE] ETH Zürich describes dreamcore as familiar scenes that are hard to place, including impossible proportions; Jared Pike’s *Dream Pools* frames endless pool environments as eerie nostalgia. [ETH Zürich](https://dbt.arch.ethz.ch/latent-spaces/) · [Jared Pike](https://www.jaredpike.art/projects/dream-pools/)
+- **Generation-driven weirdness.** [INFERENCE] Use perfectly flat ground, exact repeated hills, a corridor or pool that returns to itself, an elevated road over clouds, oversized rooms, or a horizon with no visible edge. Favor one simple rule repeated cleanly over unrelated noise. [SOURCE] Liminal spaces often use familiar passage places with their expected people or activity absent, making them uncanny. [Liminal space](https://en.wikipedia.org/wiki/Liminal_space) [SOURCE] ETH Zürich describes dreamcore as recognizable but ambiguous scenes. [ETH Zürich](https://dbt.arch.ethz.ch/latent-spaces/)
+- **Atmosphere.** [INFERENCE] Try cool fluorescent light, a weak warm pool of color, low horizon fog and sparse room tone (fluorescent hum, wind, or a looping distant splash); leave large areas quiet. [SOURCE] ETH Zürich notes that looping sound and ambiguous cues help make dreamcore recognizable but not fully explainable. [ETH Zürich](https://dbt.arch.ethz.ch/latent-spaces/)
+
+## 2. Mapping to VoxelForge
+
+| Idea | Already exists / missing | Size and “plan, then draw” fit |
+|---|---|---|
+| Wrong-place props and landmarks | [CODE] Shared decorations and rare landmarks can spawn actors or instanced meshes with deterministic placements (`ARCHITECTURE.md:267-349`; `Source/VoxelForge/Public/VoxelStrateTypes.h:2407,2471`). [CODE] Generated schema-2 slots currently carry no content/visual record, and theme draws for materials, creatures and audio remain open (`COMPOSER-NOTES.md:115-117,1484-1485`). | [INFERENCE] **Small** for one authored prop kit; **medium** to make the composer select/store coherent content. [INFERENCE] Fits a resolved placement plan and later Unreal draw; these props are not Core density geometry. |
+| Flat ground and repeating hills | [CODE] Surface profile kinds include `flatField`, `periodicHills` and `mirroredRelief`; seeded phases are resolved during planning (`VoxelForgeCore.h:560-610`). No profile kind describes tiled ground materials. | [INFERENCE] **Small** to select a flat or periodic profile; **medium** for a dedicated tiled material/pattern pass. [CODE] Yes: profile parameters are recipe/plan data consumed by the Core field. |
+| Raised road among clouds | [CODE] Floating Islands is an existing family (`VoxelStrateTypes.h:196-197`); persistent ceiling/floor actors can make a cloud sea (`ARCHITECTURE.md:457-464`), and landmarks can carry a mesh bridge. [INFERENCE] There is no demonstrated Core road/path structure that couples its geometry to the island route. | [INFERENCE] **Medium** for a finite authored bridge or platform chain; **large** for a robust generated road network. [INFERENCE] A finite road can be planned as records and drawn as mesh/content; cloud actors stay in Unreal presentation, outside Core density evaluation. |
+| Endless corridors and pools | [CODE] The cave planner makes a deterministic finite room-and-tunnel graph between passage mouths (`VoxelForgeCore.h:1314-1324`); `makeCompound` emits two to four overlapping room primitives (`ResolvedLayoutInternal.h:3037-3045`). Core exposes water channels (`VoxelForgeCore.h:515-519`). [INFERENCE] The planner is not an endless loop grammar and does not specify a tiled pool basin/waterline. | [INFERENCE] **Medium** for a finite repeated room/pool set-piece; **large** for continuous repeat with reliable traversal and water presentation. [CODE] Finite rooms/edges fit plan-then-draw; truly unbounded repetition needs a new deterministic local-repeat field/streaming rule. |
+| Impossible scale, horizon and geometry | [CODE] Resolved stamps already include carve ellipsoid/arch and fill pillar/dais/monolith/platform with bounded, stable placement (`VoxelForgeCore.h:912-941`); stamps are composed after boundaries/passages (`ARCHITECTURE.md:2242-2265`). [INFERENCE] They can sell oversized objects or a standalone arch, but not non-Euclidean topology or a genuinely impossible connection. | [INFERENCE] **Small** for bounded silhouette changes; **large** for topology-changing spaces. [CODE] Bounded stamp records fit plan-then-draw; topology changes do not fit the current finite stamp vocabulary. |
+| Fog, color and sound | [CODE] Per-strate fog, skylight tint/intensity and persistent layer actors exist (`ARCHITECTURE.md:457-470`; `VoxelStrateDefinition.h:283-362`). [CODE] Composer theme draws for audio are still open (`COMPOSER-NOTES.md:1484-1485`). | [INFERENCE] **Small** to reuse fog/light settings; **medium** to author a coherent audio/theme selection. [INFERENCE] Fits a presentation record selected before draw, but remains outside Core density planning. |
+
+[CODE] The game design requires every strate to keep a findable open-air entrance and exit and says anomalies should be rare and stand apart from grounded neighbours (`GDD.md:132-153`). [CODE] The `motif_family_override` prototype path is restricted to resolved SurfaceWorld/flatField recipes (`Standalone/Source/WorldAssemblyPrototype.h:921-943`); the shared stamp vocabulary itself is broader.

+## Recommended first slice
+
+[INFERENCE] Author one rare SurfaceWorld `flatField` layer with a single familiar doorway or small house mesh placed alone at an implausible scale, plus low horizon fog and one soft light tint. Keep the rest empty; the viewer should recognize the object before noticing the place has no sensible context. This uses existing profile, placement and atmosphere hooks, so the screenshot slice is **small** and does not require a new density family. [CODE] The mesh placement/presentation remains separate from Core’s density plan, and generated schema-2 slots do not yet carry its visual record (`COMPOSER-NOTES.md:115-117`); a composer-ready version will need that record and theme tags.
