+# VoxelForge — read-only design review: per-block bit flags (masks) to skip work
+
+You are reviewing an idea against real code. **Do not edit, create or delete any file, and do not build or run
+anything.** Read code and reason. Be thorough; mark each claim as [CODE] (with file:line), [MEASURED] (from a report),
+or [INFERENCE].
+
+## Context
+
+VoxelForge Core (`Standalone/Core`) generates a density field: negative = solid, positive = air, 25 cm voxels, 32³ tiles,
+LOD0–8 clipmap, marching cubes. The production mesher for the standalone path is in `Standalone/Source/...`, and Core is
+also compiled into Unreal. Same seed must give the same world on every machine and worker count; byte-identity with
+older versions is NOT required.
+
+Branch `assembler/world` (HEAD `7022d02`'s parent line, currently `4041d4b`) has the smooth inter-strate tunnels.
+Readiness target: LOD0–2 near terrain in ~1 s on arrival. Measured today: SW ~0.7–0.8 s, VS ~0.9 s, FI/TN ~1.0 s
+headless. In Linux UE, start→LOD0–2 is ~2.2–2.5 s. At 30 m/s in UE, near coverage is ~40%.
+
+Reports to consult: `Standalone/Research/WorldAssemblerM3/Linux1*/REPORT.md`, especially:
+- L77/L87/L117, cost census;
+- L124, shape gate and per-strate timings;
+- L125/L126/L128, tunnel prepare: per-segment work, 67–73% pair overlap, support up to 7.9 m;
+- L128, where an exact one-owner slab scheme halved pairs but got slower because of per-sample ownership tests.
+
+Tile skipping already exists at tile level: box verdicts / classify, where all-solid or all-air tiles are skipped.
+
+## The idea (from the owner)
+
+Keep bit flags per block (1 bit per voxel, or per small brick of e.g. 4³ or 8³ voxels): for example "certainly deep
+solid", "certainly deep air", "near a surface", "touched by a tunnel", "already evaluated". Use them to skip work in
+generation and meshing, and possibly elsewhere (collision, streaming, edits, AI/nav, lighting).
+
+## Questions
+
+1. Where does time actually go per tile today, and which of that work a mask could skip? Cover density fill,
+   classification, mesher (marching cubes, normals/gradients, skirts, seam refinement), passage prepare, and composition.
+   Use measured census numbers where they exist.
+2. Which flags are sound? A flag must be a proof, never a guess. A mask "certainly solid" must be derived from a
+   conservative bound (the bound must be the supremum of what the evaluator produces), or the mesher will delete
+   surfaces. Which bounds already exist in the code (box verdicts, interval bounds) that a brick-level mask could reuse?
+   Name the existing hazards. For example, `Identity` means `Sdf >= T`, and `ClassifyTile` proving below-TerrainZ solid
+   would delete 3D caves.
+3. Granularity: per-voxel bits vs per-brick (4³/8³) vs per-column. What does each cost to build, versus what it
+   saves? Consider SIMD and cache behaviour. Marching cubes needs only cells whose corner signs differ, and gradients
+   need a halo.
+4. "Already evaluated" or "checked" flags: where would they be correct (memoisation of identical queries), and where
+   would they be wrong (nearest-of-many queries like the tunnel segments)? Is there repeated identical evaluation today,
+   for example halo samples shared between neighbouring tiles, or skirt/seam re-queries?
+5. Other uses: player edits (diff layer), collision-only server tiles, streaming priority, nav. Which would a mask
+   genuinely help, given the multiplayer rule (replicate seed + layout + diff, never geometry)?
+6. Recommendation: the one or two mask designs most likely to pay off, with the expected gain (a range, marked
+   inference), the measurement that would prove or kill each, and the risks. Keep it short.
+

+[INFERENCE] **Improve the existing brick-proof system; don’t add a general “checked voxel” mask.** The promising savings are avoided field/composition work and passage preparation, rather than marching-cubes classification.

L-numbers identify `Standalone/Research/WorldAssemblerM3/LinuxN/REPORT.md`.
+
+[INFERENCE] Evidence limitation: Linux128 is absent from this checkout. Its supplied 7.9 m support and slower one-owner result remain unverified here. The reports below span different revisions; their percentages must not be presented as today’s census.
+
+**1. Where time goes**
+
+[MEASURED] L77’s exclusive FI/TN LOD0–2 worker account:
+
+| Work | FI | TN |
+|---|---:|---:|
+| Total worker CPU/view | 23.02 s | 21.50 s |
+| Passage composition | 65.9% | 65.4% |
+| Support | 14.2% | 13.5% |
+| Base field | 3.2% | 3.3% |
+| Bands / dispatch | 2.3% / 3.7% | 2.6% / 3.6% |
+| MC / skirts / refinement, excluding field work | 1.6% / 0.1% / 7.5% | 1.2% / 0.2% / 8.6% |
+
+[MEASURED] Grid fill occupied 19.058/17.377 worker-seconds, **overlapping** those phase categories. L117’s later census found support zero; its smooth-tunnel regression concentrated about 95% of added tile CPU in passage-feature tiles. Cell classification stayed flat; gradients became cheaper. Thus L77 identifies historical leverage, not current percentages.
+
+[MEASURED] L125 preparation averaged 514/130/4.1 ms worker work at LOD0/1/2. LOD0 evaluated 3.11–8.49 million segment/sample pairs with 67–72% overlap, although the exact band occupied only 5–7% of grid samples. L126 reduced floor-profile calls 20–23% without useful readiness improvement.
+
+[CODE] Brick skipping already exists: configurable block verdicts, required-sample masks, and active-block gradient halos (M:646,1053). MC already rejects cells without sign crossings before interpolation/gradients (M:2186). Gradient memoisation exists (M:1956). Skirts issue separate density queries (M:2491); refinement has its own stage (C:2975).
+
+[INFERENCE] A pre-evaluation proof can save density, composition, and subsequent MC work. A sign mask constructed after density evaluation saves only downstream scanning. Classification itself costs work; no isolated current classification percentage is established by these reports.
+
+[MEASURED] L124’s shape gate alone took 179–226 ms, with no near-tile admissions before completion. L87 additionally measured a 107–153 ms far-parent gate and no headless collision wait. Tile masks cannot directly remove these gates or explain the supplied UE/headless gap.
+
+**2. Sound flags and hazards**
+
+[INFERENCE] For final density \(D\), solid requires an upper bound covering the evaluator’s supremum, \(U<0\); air requires a valid lower bound \(L\ge0\). “Deep” requires an explicit margin. Unknown must stay unknown. A crossing proves an MC-active cell; uniform sampled signs do not prove an entire continuous volume surface-free.
+
+[CODE] Reusable proofs include:
+
+- S:5428: halo-expanded box classification.
+- S:5974: exact surface-column extrema over the MC lattice.
+- S:6019: floating-island density intervals.
+- S:5197,6032: native cave intervals.
+- S:5949: stamp interval composition with outward numerical padding.
+- O:6998: operation-specific inactivity from SDF lower bounds.
+
+[CODE] These proofs have guards: passage overlap returns unknown (S:5687); unsupported stamp composition returns unknown (S:5655); stratum crossings are rejected (S:5900). The mesher distinguishes uniform candidates from `bSkipSafe` certificates (M:715,756), and otherwise validates candidates against actual samples (M:1838).
+
+[CODE] For gated modifiers, `Identity` can mean `Sdf >= T`, not `abs(Sdf) >= T` (O:1496,6998). Noise bounds cannot assume nominal `[-1,1]`: FBM and unclamped cellular bounds are explicitly discussed at O:848,301.
+
+[INFERENCE] Additional hazards: confusing internal SDF with final density; certifying base terrain before caves, tunnels, shells, stamps or edits; using lattice proofs for off-grid queries; ignoring rounding or gradient halos. A below-`TerrainZ` solid rule applied to 3D caves deletes caves. “Touched by tunnel” should mean conservative candidate overlap; only **proven untouched** authorizes omission.
+
+**3. Granularity**
+
+[INFERENCE] Storage per flag for 32³ cells:
+
+| Granularity | Storage | Construction/tradeoff |
+|---|---:|---|
+| Per cell | 4 KiB | 32,768 decisions; expensive unless derived during necessary work |
+| 4³ bricks | 64 B | 512 proofs; tighter boundaries, more proof/halo overhead |
+| 8³ bricks | 8 B | 64 proofs; cheaper, more mixed bricks |
+| XY columns | 128 B | 1,024 decisions; useful mainly for heightfield-specific proofs |
+
+[INFERENCE] These exclude corner/halo samples, metadata and additional flags. A column bit cannot represent multiple cave intervals. Brick runs preserve contiguous X sampling and SIMD better than scattered per-sample branches; bit packing alone does not establish a speedup.
+
+[CODE] The existing implementation uses byte arrays and preserves exact samples around active bricks (M:1053–1083). Replacing densities with arbitrary same-sign constants near active cells would corrupt interpolated positions or normals.
+
+**4. “Already evaluated”**
+
+[CODE] Passage preparation precedes meshing (C:2747). Its valid sentinel is initialization, not completion: subsequent segments update floor selection, shell minima and round-distance winners, with deterministic tie-breaking (S:11520,11615,11688).
+
+[INFERENCE] Therefore first-visitor wins is invalid. Memoisation is valid only for identical queries against identical seed/layout/evaluator/edit revision and query semantics; cache the value, not just a bit.
+
+[MEASURED] L77 counted 8.6–8.9% halo points, without measuring duplicate coordinates. L125 verified 4,900 shared samples across four neighbour pairs and still recorded substantial off-grid skirt/midpoint fallbacks.
+
+[CODE] Shared-grid reuse and gradient validity caches already exist (M:1031,1956). [INFERENCE] Skirt/seam queries are reuse candidates only when coordinates and semantics actually match; “same voxel” is insufficient.
+
+**5. Other uses**
+
+[INFERENCE] Edit-dirty bricks can localize regeneration, with invalidation expanded through normals, seams and collision dependencies. Collision-only servers can skip certified empty regions, but still need boundary geometry. Streaming can prioritize potentially occupied bricks; nav and lighting need clearance/connectivity or visibility data beyond occupancy. Keep masks derived locally from replicated seed + layout + diff, versioned with that state.
+
+**6. Recommendation**
+
+- [INFERENCE] **Tune existing 4³/8³ certificates**, caching proofs and emitting contiguous required-sample runs. Plausible incremental near-ready saving: **0–5%**, with regressions possible. Measure proof time, samples avoided, halo expansion, total worker CPU and UE readiness.
+- [INFERENCE] **Pass required-region information into passage preparation**, rejecting whole segment/brick regions conservatively. Plausible near-ready saving: **0–10%**, highly uncertain because passage overlap currently vetoes proofs. Kill it if pair reduction fails to reduce preparation and end-to-end time.
+
+[INFERENCE] Both require seam/off-grid validation, adversarial bound checks, edit invalidation tests, and cross-machine/worker determinism. Preserve canonical tie-breaking; old-version byte identity need not constrain a sound redesign.

+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.

+[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.

-# L128 slab ownership
-
-Base `4041d4b`; branch `wip/l128-slab-ownership`; core version 226. Source stamp: `8682a9a088f0f02357b3b9722cda9b18a5ebce9886a13cba2d114bc0655d8c70`.
-
-Each route body uses half-open frame-plane slabs, so a boundary sample belongs to one segment. The required support is `S = r + max(4.0 + 0.21 + 0.125, 0.75 + 0.21) + 0.05 m`: bore radius plus the larger sweep/relief/corner or shell/relief reach, with a 5 cm audit margin. The largest body support is 7.885 m; the 4.5 m mouth profile reaches 8.885 m and is assigned to transition slabs. Local uniqueness requires curvature radius `R > S` (`κS < 1`). For equal adjacent chord lengths `L` and turn `θ`, this is `L / (2 sin(θ/2)) > S`. Nonlocal mutually-normal centerline pairs must be farther apart than the sum of their supports. Intersections between different passages remain a deterministic field union.
-
-All three owner-world routes pass the body curvature and self-separation checks; no route control points changed. Minimum body curvature radii are 11.565 m (0–1), 14.042 m (1–2), and 8.869 m (2–3), giving at least 0.984 m margin over body support. Route 0–1's 8 tight mouth joints and 5 nonlocal mouth pairs use transitions. The prepared/off-grid query paths share ownership. The audit tested 33,813 support samples: zero missing or duplicate owners, and both negative controls were detected.
-
-The slab projection supplies `s` to the continuous floor profile `h(s)`; round-distance does not choose floor height. Across 459 floor roots at nine stations, the largest adjacent root step was 1.765 mm and the largest absolute station offset was 7.884 mm. Seam audit: 4,900 shared samples, zero mismatches. Fast suite passed (264 checks, 5 diagnostic); walkability passed. Clang and GCC W1/W8/W12 hashes matched across all three datasets. The 23 L125 captures are in `captures/L128/` (19 pass; 4 low-contrast with geometry visible).
-
-**Performance bar failed.** Five interleaved runs per group across all four strates and W8/W12 put LOD0–2 readiness 14.8–28.0% behind L109 and 8.0–20.6% behind `4041d4b`. The five-run 30 m/s UE median also failed versus `4041d4b`: near coverage 31.46% vs 40.22%, moving far holes 5.66% vs 3.46%, p99 tick 12.42 ms vs 10.80 ms, and worst tick 14.35 ms vs 13.27 ms. L128 is not ready.
-
-Linux UE host build succeeded (27/27 actions, `-NoUBA -MaxParallelActions=4`); Unreal ran without `prlimit`. No commit made. Detailed logs are under `Saved/Linux/l128/`.

+# 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.
