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.
