One current-state page (shipping behaviour, references with sources, gaps, verification, closed lines), linked from CLAUDE.md. Removes the L86/L88 passage/boundary ablation switches and the unused legacy route-grade audit; inventory of every kept switch in the report. Output identical: 24/24 + 18/18 hashes, fast tier, walk/seam audits, UE host build; timing unchanged (-0.2%, CI spans 0). No Source/ changes.

# 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/`.
