Overnight task 2. Every claim here is end-to-end wall clock on a real 128^3 export,
not a profiled bucket, because the last two rounds shipped large bucket wins worth
0% in reality. Measurement floor is ~17% run-to-run; only Part 2 cleared it.
PART 2 -- KEPT. Density-grid reuse.
The mesher samples an expanded grid (-1..Cells+1), so adjacent tiles re-evaluated
their shared boundary planes. Measured: 2,744,000 requested samples contained
495,909 duplicates -- 18.07% of the field generated twice. A run-scoped read-only
lattice (FVoxelSharedDensityGrid) owns each world sample once and hands it to both
adjacent tile grids. Duplicates now 0.
128^3 TunnelNetwork seed 1337 slot 1, freshly built binary:
before 2.603 / 2.693 / 2.697 s
after 1.488 / 1.499 / 1.486 s -44.6%, 1.80x
Geometry SHA-256 98eaad61..d3c4f IDENTICAL to the pre-change binary's output.
153,740 triangles either way. Pure win, no field change.
The lattice is deliberately not a UObject and not a cache with eviction: ownership,
lifetime and iteration order stay explicit. A malformed or incomplete lattice is
ignored and falls back to the canonical generator path rather than altering geometry.
PART 1 -- REVERTED. Block-level empty-space early-out.
**0 of 4,096 blocks were safely classifiable**, and the attempt made it 85% slower
(3.632 -> 6.735 s). No unsafe bound was retained.
⇒ This is a finding, not just a failure: our conservative bounds are too loose to
prove ANY 8^3 block uniform. Hierarchical evaluation of any kind is blocked until
we know which operator has effectively unbounded reach. Next task.
PART 3 -- REVERTED. Task granularity.
15 workers, 64 tile jobs, mean job 0.594 s, launch fringe ~14.1 us. MinBatchSize=4
was 1.09% SLOWER end-to-end despite a better bucket time -- exactly the trap this
task's rule exists to catch. Default stays 1. ParallelForWithExistingTaskContext
not adopted.
PART 4 -- NO CHANGE. Renderer audited over 3 runs (8.736 s total, 1.483 s raster).
Mesh and BVH are already reused across viewpoints; no per-pixel heap allocation, no
redundant remeshing. Nothing gross to fix; it benefits from the above automatically.
STILL OPEN: the spatial index from ee89c4d has never earned its keep in wall clock
and accounts for ~214 MB of measured allocations. Codex proposes an on/off ablation
then removal if confirmed. Not done unilaterally.
⚠️ PROCESS NOTE: the agent reported "build passed" but the runtime DLL was still
from 03:07 while sources were edited at 05:22/05:42. My first three verification
runs measured the OLD binary and showed no change. Always check binary timestamps
against source timestamps before believing a measurement.
Cumulative on this region: 342.2 s -> 16.2 s -> 2.62 s -> 1.49 s (230x).
Determinism: identical hashes across all repeat runs. Build clean. Nothing outside
Plugins/VoxelForge touched; RealtimeMeshComponent untouched.
