Two admission blockers found by per-frame decline codes: the near reserve held
four slots idle after LOD0 was done (coarse capped at 6), and finished-but-
unapplied results counted against the task cap. Admission now counts queued +
running tasks; near reserve releases once the walkable ring is ready while
stationary (voxel.StreamingDynamicNearReserve, default on). Walkable ring
0.65 -> 0.58 s, full LOD0 2.28 -> 1.44 s, busy workers 2.2 -> 5.6 of 10.
Old behaviour behind voxel.StreamingLegacyPendingResultCap. RMC source reviewed

SurfaceWorld and FloatingIslands plans generate at startup from the resolved seed,
strate types and heights (hashed, cached). Imported JSON is an opt-in override (off by

island LOD0 p95 ~155 ms misses the 133 ms sprint deadline (legacy ~43 ms); the island

Owner saw content floating above native terrain, spiky triangles, reversed carve/fill and late relief.

Luna, M1 round 1 of 4 (plan in Standalone/ASSEMBLER_M1_REPORT.md):
- Versioned fixed-scale world manifest (the shipped plan format) and the Core block
contract: point evaluation, interval-or-unknown, influence bound, detail envelope, channels.
- Interval audit: 256 boxes / 6,912 samples, 0 missed, 0 unknown; a deliberately false bound
is detected (negative control).
- Native Heightfield2D with biome input: 4,096-point hash fae2721c052aec5c identical at
W1/W8/W16; point queries 2.059 ms vs 62.115 ms legacy -- but NOT a match yet (mean density
error 274 voxels, 2,261 sign mismatches vs the legacy surface). 45 mesh-free Core queries
match direct evaluation exactly. Existing cave world unchanged (walkability, 64/64 tiles).
- Open: collision readiness, a valid full-view timing (viewer captures were occluded/empty;
top-down height maps are the only usable pair).
Also carries the design doc's owner decisions (fixed water; player edits unrestricted, route
law for automatic changes only) and three plugin files + BuildHost scripts that earlier round
commits had missed (also fixed on unreal/core-integration as 2574b56).

Stopped by the owner's decision (in-game lit captures were eating the round); he judges the look in
game instead.
1. Fall-through with the research field: fixed. Deep drop, gate on: 2 holds (0.50 s), min foot
clearance +43 cm; gate off: penetrates (-278 cm). Stress fixture offsets converted to metres.
2. VOXEL_SIZE 25 -> 12.5 cm. Physical sizes kept in metres (player, steps, gate, insets, research
field sizes, dig radii, test thresholds); class defaults that count chunks/voxels doubled
(ClipRadius 6, RenderDistanceChunks 1536, ViewDistance*, StrateViewMargin 6,
PawnCollisionRadius 2, SkirtCells 4, EdgeSealThickness 128, decoration spacings, density volume
res 256). Asset values override these defaults: the owner must double his own.
Ring scale, six workers, idle, step-2f field before the look changes: 64 m cube (519^3) 4.55 s;
32 m cube (259^3) 0.95 s.
3. In game: tiles go through the brick evaluator (proved by a log marker); profile switch rebuilds
the loaded world (~5,800 tiles); full-detail fill 12.4 s after spawn in the visible-window test.
4. Look: round winding tunnels, per-column ellipsoid/lattice caches. All step-2f geometry gates pass
at 12.5 cm (0 crumbs, 1 solid component per profile, solid share 69-87%). 259^3 ring, six workers:
1.08-2.02 s (worst HyperComplex) -- the 600 ms gate FAILS. Lit captures failed (hidden/off-screen
window, then blank frames); not pursued.

Editor-only, default off (voxel.ResearchRedefinedDensityField). The redefined field is a seeded,
periodic cross-corridor pattern per strate plus the authored passages, landings and a shaft tree,
with four value-noise detail bands at every near-surface 25 cm sample and sound 8^3 brick proofs.
259^3 ring, six workers: 308 ms median (467 ms without skips) vs 8.9 s for the live field.
Detail, boundary-artefact, determinism (1 vs 6 workers, two runs) and bound-audit checks pass.
Why it is not a pass: the slices show a mostly-solid field with a few straight corridors, where the
owner's world is mostly open space; rooms, the tunnel network, composer recipes and archetypes are
gone. Much of the speed comes from 60% of bricks being proven solid in that simpler world.
What it does show: detail at full resolution plus brick skipping costs ~80-130 ns/sample; the
cost of the live field is how rooms/tunnels/passages are represented, not the detail or the lattice.
The two walkability tests were redirected to the research field in the working tree; that change
is NOT committed (saved as scratchpad step2d-test-redirect.patch) so they keep testing the live world.

Rebuild plan step 1 (RESEARCH-SPEED-2026-09.md), all behind default-off switches.
A. Direct cook on a dedicated thread, 27-tile support cohort: core cook p50 1.50 ms, p95 2.28 ms;
a 3,949-tri tile 1.67 ms extract+cook. PASSES the 10 ms gate. Through RMC's route the same
support bodies became ready 8.46 s p50 / 10.80 s p95 after their meshes existed: FAILS 150 ms.
Exact-target capsule sweep confirmed (0.75 ms after body update).
B. 100 rapid underfoot digs on CMC with a field override: 883 false-support frames, 0 false-air,
0 invented velocity. CMC's floor comes from collision-scene traces -> step 4 = field-aware Mover.
C. 341 prequeued tiles, render on: cap 4 = 238 applies/s, cap 8 = 476, cap 16 = 639 (drain p95
2.22 ms vs 2 ms gate); first visible 1 frame after release; no RT/RHI backlog. Tune drain,
no grouping needed yet.
D. Same 128^3 region, 64/64 tile hashes equal in export and game. The "263 ns/sample" was export
WALL time with 15 workers sharing a lattice (~3.4 us CPU/sample); game tile time includes
meshing and duplicated borders (+22%); contention cap 1 vs 14: 74 vs 112 ms per tile.

Compiled and run (cap 14 / 12 / 8), then stopped: another app held 12.5 GB, free memory fell
under the 6 GB launch floor and processes failed to start (STATUS_DLL_INIT_FAILED).
Measured so far (owner world, 120 s windows):
- 343 L0 tiles, request->collision-ready p50/p95: cap 14 = 262/440 ms, cap 8 = 196/238 ms;
scheduler queue wait p95 141 ms -> 0.9 ms. Initial support tile at cap 14: RMC submit->body
7.47 s, first check->ready 9.73 s; at cap 12: 0.33 s / 2.54 s; at cap 8 a 3,949-tri tile
reached body update 2.8 ms after RMC submission. Waiting, not cooking, dominates.
- NOT confirmed: a capsule sweep hitting the exact target body (the 0.75 ms hit was another
component); the 10 ms core-cook and 150 ms/27-tile thresholds are unscored.
- CMC cannot take a same-frame density floor: FindFloor/ComputeFloorDist trace the collision
scene. Underfoot digs (100-dig test), upload throughput (render-enabled caps 4/8/16) and the
8x per-sample question are not run. Per-sample profiling was fully disabled in these runs, so

1. Collision cook breakdown (request -> ready), critical support tile:
spawn (0,0,-1): generate 107 ms, apply < 1 ms, RMC submit->body 479 ms, total 587 ms;
deep floor (0,0,-7): generate 82 ms, RMC 1,441 ms, total 1,548 ms.
Almost all of the wait is inside RMC (end-of-frame update + async pool + Chaos cook + body
install, not separable from our side). Critical priority does not shorten it. Collision is
async, complex-as-simple, fast-cook off; skirts are ~16-18% of collision triangles.
No cook change made. Startup outlier: first support tile waited 2.09 s for its game-thread apply.
Underfoot dig: a carving brush that intersects the pawn's capsule and support tile now
disables the old body and withdraws readiness on the carve frame: 0 frames standing on removed
ground (replacement 91.8 ms later). 8 neighbouring digs: 0 gate frames. Gap audit 0.
2. Stack sampler, 49.4 s game path: top resolved leaf was the profiler's own
VoxelDensityProfile::BucketFromName (4.86%). Linear label scan -> CRC-keyed lookup with exact
compare: 59.26 -> 57.87 ms/tile (-2.35%), 980/980 tile hashes identical.
3. Measured only: F (classifier mode 1, no exact check) +48% worker CPU, 0/980 tiles differ ->
not worth it. H (handoff component scans) p95 0.07 ms/frame -> not worth it.
E (FullResClipLevels=1): worker CPU 56.7 -> 35.7 s, settle 9.6 -> 7.0 s, crossing samples
-30%; changes the look, owner's decision.

- Dig near the pawn: a same-tile collision recook withdrew readiness although the old body was
still installed, so the gate held a standing pawn (957 of 1,931 frames over 8 near digs).
A tile now stays ready during a recook while collision is still wanted and its existing body is
valid. After: 0 gate frames, 0 falling frames over 2,604 frames. Dig directly under the pawn
still falls (~127 cm, max ~502 cm/s). The reported "accelerating toward the ground" was not
reproduced; the false hold is the measured part.
- See-through: the retire logic only waited for replacements that overlapped the old tile in
volume and missed desired neighbours touching at a face/edge/corner. Handoff now includes
contact. New surface-witness gap audit (24 surface points per tile, skirts excluded, catches an
injected early hide). 6000 cm/s walk, 75 s: 3 gaps / 51 frames / longest 603 ms -> 0.
Dig session: 0 -> 0. Overlap audit and edit ghost stay at 0.
- bEnableDensityVolume defaults to false; when off: no volume, no fill thread, uploads or tick
work, no volume-dependent proof bypass; terrain MIDs get VolP5.z = 0 (enable off), other VolP*
black, VolTex* null, so M_Test1's volume nodes return their neutral result.
Gate: deep gate-on passes (79.9 m, 3 holds, -0.101 cm), gate-off penetrates (-5.1 cm).

From the outside performance review (items 1-4; item 5 prototyped and reverted).
1. Collision gate: a support request outside the stamped desired set was cancelled by the rebuild
it forced, and the gate held the pawn with gravity 0. Baseline deep-drop (floor at (0,0,-7),
outside the aligned L0 ring): 1 hold of 30.0 s, never released. Fix: the target and 3 tiles
below are retained through rebuilds at CollisionCritical; hold only when the swept capsule is
about to enter pending support; release restores movement mode, gravity and downward speed.
After: 3 holds, 2.21 s total, 112.8 m horizontal progress; gate off still penetrates (-7.4 cm).
2. Suspected cleanup regression (out-of-layout stacks): not real. 44 paired boundary tiles,
30.9 ms vs 32.6 ms at b4ac996, hashes 44/44 identical. No change.
3. PawnCollisionRadiusChunks (new, default 1): L0 tiles outside the collision set stay visible
without Chaos cooks; anchors and the gate's support column are unioned in. Cook requests
~217/min -> ~30/min (-86%). Critical support ready time did NOT improve (9.5 s -> 10.6 s in the
deep-drop fixture; the wait is the cook itself, ~7.4 s cook-to-ready there).
4. Dig: exact pre-edit L0 density cached (one 35^3 grid, 171.5 KB), carve replays current mods on
it. Sync remesh 99.4 ms -> 4.7 ms. 16/16 random carves hash-identical to full regeneration.
5. Parallel grid fill for the critical tile: 16/16 hash parity, but the waited-on tile was already
meshed; the wait was collision cooking. Reverted.
Review G answered: M_Test1 still ray-marches VolTex0 (custom HLSL mini-sun shadow), so the density
volume is live. Known and left alone: outside the strate layout the fallback density can be solid
while the gate treats those tiles as air.
Tests: VoxelForgeCollisionDesiredTilesTest, VoxelForgePreEditDensityCacheTest; no-overlap, edit
ghost, descent corridor pass.

Stopped mid-round: the PC ran out of memory (another app held 11 GB), new processes failed to start
(0xC0000142), and the round ended without verifying anything after the edit.
Confirmed in code (performance review finding 1): a support request outside the stamped desired set
forces a rebuild that cancels it, the gate asks for one unresolved tile at a time, and it holds
before the pending tile is anywhere near the pawn's next step.
Uncompiled edits: a short collision-only support column retained through desired rebuilds and
prioritised; hold only when the swept capsule is about to enter a pending tile; downward speed
restored on release; opt-in deep-drop fixture (carved shaft) in the stress harness.
Evidence so far: shallow 10-voxel fall, gate on, before the edit: 1 hold of 1.51 s, clearance
+120.6 cm. The 80/160-voxel attempts spawned OUTSIDE the strate layout (support unavailable,
zero holds) and failed the penetration check at -11.1 cm: not the reviewed loop, but worth a look.
Compile risks: GetGravityZ(), TSet pruning in the rebuild, the fixture's carve/log arguments.

Every strate now generates through its operator stack: authored
definitions, cooked-season entries (recipe or native) and editor
composer candidates alike. The per-strate opt-in and the archetype
switch it guarded are gone.
- Remove UVoxelStrateDefinition::bUseOperatorStack and the season
wiring that set it; UsesOperatorStackForChunk now only says whether
the slot has a known archetype.
- GetDensityAt always builds a stack (composer, then recipe, then the
native archetype stack); a degenerate zero-height strate stays air.
- Remove the startup opt-in warning, the operator_stack startup-trace
field and the four "Cave Bail Not Op Stack" stats (the remaining
bail is counted by Cave Bail No Stack).
- Explore commandlet: drop -opstack and the operator_stack fields;
VoxelForgeTest.ps1 no longer passes -opstack=1.
- Tests: FTestWorld::Build loses its bool parameter; legacy-vs-stack
comparisons (MazeSeam, VerticalShaftSeam, TerrainDetailLiveness,
WorldEdgeSeal, TilePostReach) collapse to the single stack path.
This changes terrain for any strate asset that did not already have
the opt-in ticked.

The far sheet ring was already gone from the runtime; this removes what
was left of it:
- UVoxelSettings::bFarSheetRing / FarSheetSpanLevels, the
voxel.TestFarSheetRing switch, and their log/trace/dump fields.
- The sheet branch of VoxelClipmapDesiredTiles (FParameters sheet fields,
OuterShell sheet level, sheet ring emission). Output for the runtime
configuration (sheet off) is unchanged: same rings, same alignment.
- Tests: VerticalStrateReach now asserts the sheet-free selector (its
expected counts were stale since the aligned-ring change 85a803b:
LOD0 343 -> 512); ClipmapNoOverlap drops the sheet sweep cases and the
frozen 7486c29 oracle's sheet branch. New expected values were computed
with a Python port of the selector that reproduces the test's existing
635/594487 and 508/74295 measurements exactly; all 5,145 sweep cases
pass (no overlap, full coverage).
- Tools/VoxelForgeTest.ps1 no longer passes voxel.TestFarSheetRing or
reports far_sheet_ring. The sheet_tile dump field is kept (the parity
compare reads it).
Also removes settings nothing reads: CeilingViewMultiplier,
CeilingBandChunks (pre-clipmap ceiling band) and DensityVolumeMaxTasks
(the volume fill runs on its own thread). Saved assets that still carry
these values load normally; the values are ignored.

Move closed audits, task briefs, design rounds, perf reports, the OPSTACK
plan/progress logs and WORK-NEXT.md into Docs/archive/ (git mv, history kept).
Whitelist Docs/ in the strict .gitignore, ignore Tools/**/__pycache__/, and
remove the tracked .pyc. Repoint references in the kept docs and in non-test
source comments to the new paths.
The old criteria (travel distance) could not tell a working gate from a broken one: every run,
gate on or off, ended at (455.7, 0, -58.1). That spot is measured air ~1.2 m above a real floor
(density zero-crossing at world Z ~ -275.7 cm), so it is a terrain trap, not a fall-through.
The stress test now drops the pawn fast onto an unready support tile (0,0,-1) and samples the
density at the capsule feet every frame, sweeping at <= half a voxel between positions. PASS =
no measured clearance below -5 cm.
Owner config (radius 3, max level 6, distance 768, sheets off):
- gate on: 10/10 PASS, min clearance +120.5..+120.9 cm, one hold of 0.43-0.47 s each,
support submitted in ~0.7 ms, collision ready in 0.43-0.47 s
- gate off: 3/3 FAIL terrain_penetration, clearance -5.7..-8.1 cm
Edit-ghost, clipmap no-overlap sweep: pass. Test-harness code only; no production path changed.
This validates a49725d.

- RequestCollisionGateSupportTile submits the level-0 support tile immediately, even before the
first desired set; the desired rebuild adopts the same pending key (1 early request, 1 adoption,
1 ready callback in all 10 runs). First check -> submit went from ~2.2 s to ~1 us.
- The 2 s gate release timeout is removed: at the owner's startup the game thread applies nothing
for ~2.2 s, so the timeout always fired and dropped the pawn. The gate holds downward Z only;
horizontal movement stays free.
- Controls (previous round): legacy selector+reconcile failed the stress repro 0/5, aligned 1/5,
so 85a803b did not regress the gate.
NOT VALIDATED: the stress repro's pass criteria were rewritten (support submitted/ready, a hold,
progress during a hold). 10/10 "pass" under them, but every one of those runs, and the gate-
disabled run, ends stuck at (455.7, 0, -58.1), ~1.55 m below the Z~97-100 at which the old
passing runs travelled 113 m. Whether that spot is a real pit or the pawn below the surface is
unresolved; until it is, a pass under these criteria proves nothing about falling through.

The owner reported a wall staying visible after he carved through it, and overlapping LODs when crossing slopes at speed. Two causes: an edit only re-meshed the level-0 tiles of the touched chunks, so coarser tiles kept pre-edit geometry until something else re-queued them; and superseded tiles stayed drawn until the budgeted teardown reached them.
Now: edits fence late pre-edit async results and re-mesh every affected loaded/pending level; a replaced tile is hidden as soon as its replacement is fully covered, while destruction and collision removal stay budgeted (the anti-spike rule that made teardown budgeted in the first place). Load-before-unload is unchanged, so no holes.
Measured: edit ghost 40.095 s (unresolved at test exit) -> 0.172 s; 6000 cm/s slope overlap 19.952 s with 153 overlapping pairs -> 0.000 s with zero events. Gate stress PASS (113.68 m, 2 holds, 0 full stops). Apply-frame cost peaked at 0.979 ms against a 2 ms budget.

The sheet system models terrain as one ground and one cap height per column, which cannot express this world's overhangs, floating islands and open sky; three attempts to fix the MC/sheet seam produced holes, then caps over the void, then both. Measured alternative: cover the render distance with real marching-cubes tiles and switch the far-sheet ring off.
Benchmarks at RenderDistanceChunks=768, all tiles loaded at steady state: L4 57,473 tiles / 30.1M tris / 837 MiB / 2,514 s worker / 296 s to settle; L5 10,841 / 8.1M / 226 MiB / 375 s / 108 s; L6 3,281 / 2.9M / 82 MiB / 127 s / 77 s. Defaults now MaxClipLevel=5, bFarSheetRing=false. Invariants: strate crossing PASS, gate stress PASS (140.06 m, 0 full stops), determinism PASS with 10,841 tile hashes identical vs -voxel.CrtFma3=0. Peak memory ~4.2 GiB in all three.
Owner action required: his DA_Settings still serializes MaxClipLevel=3 (asset edits are out of scope for Codex), so his world needs that value raised to 5 to use the new far field. At twice the distance the estimate is ~39.5k tiles / 29-30M tris / ~0.8 GiB / ~1,500 worker-seconds, which would want L6 rather than L5.

ParameterRoll's 5 false box verdicts are fixed: fine room-graph intervals are now checked against exact lattice samples before a uniform verdict is accepted, while the SDF bound keeps its conservative lower bound. Lattice sweep 600 tiles / 0 violations; ParameterRoll passes with 9,577 exact lattice leaves and 774 interval disagreements caught.
The owner's ceiling holes are NOT explained by this: in his recorded session outer_classifier_mode=0, solid-proof skips were 0, and air-proof skips were outside the strate. The trace points at the far-field sheet system instead: sheet tile L5 (0,1,0) is deliberately empty inside the sheet hole while its bridge tile L4 (0,1,-1) meshed 662 ceiling triangles. Continuous ceiling is NOT verified: every render launch failed (D3D12 driver error, stalls before map load, the 6 GB cap), so the round produced no matched after-render.
Cost note: this round used 3.46M tokens on Luna 6 at max, most of it burned on failed render launches. Verification by render is unreliable in this harness; verify ceiling continuity from tile/geometry data instead.

The owner marked missing tiles around him in a 64-chunk surface strate with RenderDistanceChunks=768. Cause: the desired-set vertical clamp used the player's small window (bClampViewToStrate on, ViewDistanceUp/Down=5, margin 3), so at chunk Z=0 only [-5..3] was ever requested; the rest of his strate was never asked for. Second cause: with MaxClipLevel=3 and a two-level sheet span the outer ring is level 5, while the marching-cubes loop stopped at 3, leaving level 4 empty.
The band now follows the player's whole strate plus margin ([-66..3] in the pinned case) and keeps the small window only when there are no strate bounds (inter-strate gap), so the hidden-rock column the clamp exists to avoid does not return. Bridge shells are emitted up to the level below the sheet ring, filling level 4.
Pinned case desired tiles per level, before -> after: l0 343->343, l1 218->218, l2 129->178, l3 80->178, l4 0->178, l5 4801->9586; total 5,571 -> 10,681 (+91.7%). New focused fixture VoxelForgeVerticalStrateReachTest fails before and passes after. Stress repro passes (140.089 m, 4 holds, 0 full stops); strate crossing passes (0 holds, 0 floor overlap).
⚠️ Cost not established: the post-fix perf sample was incomplete and showed a 55.7 s p50 queue wait, which may be the fixture's extreme settings (768 render distance -> 9,586 sheet tiles) or a real backlog. Measure in the owner's world before merging.

The owner could not do speed runs: the gate stopped the whole pawn whenever streaming fell behind. Measured at 6000 cm/s on 0dd45ca: one 18.9 ms hold followed by terminal non-resume, 4.522 m of a 120 m route. The gate now cancels only downward motion into unresolved ground, keeps horizontal velocity and player control, ignores air and out-of-layout tiles, and requests a blocking support tile at high priority. voxel.CollisionGate (default 1) disables the safeguard for stress runs; it is snapshotted at start-up.
After: stress run PASS -- 4 holds, 1.881924 s total, full_stops=0, 139.947 m of 120 m. Strate crossing PASS with pending_floor_overlap=0 and the lower strate reached. Static perf sanity PASS. Verification budget kept small on purpose (no suite, no exports): the owner's complaint was that a one-line request triggered a thousand tests.
Known, NOT fixed here: the surface-fall repro fails as surface_ground_timeout -- the pawn now lands, but on top of the authored (0,0) entry at Z=799.5 cm instead of dropping to its floor at -150 cm. The gate has released by then; this looks like the entry opening being capped, i.e. the owner's 'surface generation is bugged'. Next round.

The owner fell through a surface-only world and hovered in mid-air: log showed 'ready=1 predicted_wait=1' for 50 s. Two causes, both fixed: (1) engaging the gate zeroes velocity, so the predicted-support probe never re-ran and the gate kept waiting on the tile remembered from when the pawn was still moving -- the prediction is now re-derived every tick from the pawn's current pose; (2) a tile the streamer never requests (out of layout, or outside the desired set) could never become ready, so the wait was unbounded -- such tiles are now logged and treated as nonblocking, and any wait is bounded to 2 s with a warning.
Repro added to the harness (surface-fall scenario): before, the pawn stops at Z=1315.9 with collision_gate_prediction_deadlock; after, it reaches the ground in 2.25 s at Z=-45.6. Strate crossing still protected: 145.49 s route, max gate wait 0.109 s (limit 10 s). Perf S/M/S/M 24.265/54.262 and 23.947/53.057 s, within repeat noise. Owner and canonical geometry unchanged (44E7C813 / 94B47A1C).
Known red, pre-existing and unrelated: VoxelForge.Composer.ParameterRoll still reports false box verdicts in the owner's current single-strate surface layout (5 violations, identical in the baseline). Next round.

The harness's first full suite run showed 16 of 44 tests failing. Two were real defects in the owner's world:
1. ParameterRoll: the tile classifier could certify a box AllAir while the final field is solid there (3 false proofs found, e.g. density -2.092319 at (-192,16,-224)). Cause: the box diagnostic narrowed 'tail reach' to 'air reach', so the swept tunnel FLOOR -- which writes solid -- did not count as reaching the box. A false AllAir skips meshing, i.e. missing floor in game. The classifier now uses the same reach predicate as the final writer (swept chain, floor band, relief, room-mouth envelope) and propagates it through Mixed refinement nodes. Re-run: 1,288,143 lattice samples, 0 violations.
2. VerticalShaftEquivalence: LedgeSpacing and LedgeDepth were missing from the production TLS cache key, so a shaft could reuse stale ledge parameters. Both are now in the key.
The other 14: broken fixtures (missing staged corpus assets, a sampler leaking the shaft TLS marker between queries, stale candidate IDs, a window entirely inside the common tail) or stale expectations after this week's owner decisions (no authored tunnel floor, slope in degrees, rooms owning their interior). No test was deleted or weakened into vacuity; retired legacy comparisons stay as telemetry and the current stack is asserted instead. PassageLandsInOpenSpace now requires a real player-capsule fit in the final density at each authored landing (14/14, worst gradient 0.115723).
Suite: 42 tests green in one run, the two long op-stack sweeps green in serialized filtered runs (the 1800 s launch guard); a harness timeout-recording bug was fixed. Bounded probe exports unchanged (canonical 94B47A1C, owner 44E7C813). ⚠️ Harness perf scenario moved 50.74 s -> 53.58 s worker (+5.6%): the wider reach predicate skips fewer boxes. Measure on the game path and decide before merging.

Tools/VoxelForgeTest.ps1 runs scenarios (canonical, owner, probe, perf, tests, parity) with the known-good flag sets, isolated user/config dirs, serialized launches, an owner-process guard, and a compact result.json + summary.txt instead of 300 MB logs that Codex has to stream. Answers the owner's question 'can the commandlet reflect in-game behaviour': -gameconfig=1 makes the commandlet use the authored settings, and the parity scenario compares per-tile geometry hashes between the commandlet export and the game's streaming path. Parity PASS: 64 commandlet tiles vs 810 game records, no differing tile.
First run of the tests scenario: 44 tests, 28 pass, 16 fail (8 composer, 6 op-stack equivalence, PassageLandsInOpenSpace, StrateParamBlendCoverage). Triage is the next round: stale expectations from the floor removal and the degrees change, versus real defects, especially the legacy-vs-op-stack equivalence ones.
