Task 4 ran 11 hours and was killed by system memory pressure before it could file a report. The work survived, builds clean (0 errors), and is verified faster with byte-identical output. This commit is my verification, not its summary -- it never got to write one. THE STRUCTURAL FIX0e9df9eestablished why no block could ever be skipped: OriginSpineOp, PassageCarveOp and the active seals Lerp/Min/Max against the CURRENT density, so with an unknown incoming density their supremum is genuinely unbounded. Not a missing bound -- the operator semantics. The answer is to propagate a density INTERVAL through the stack, and that is what landed: FVoxelBoxSdfInterval + PropagateSdfOverBox on the operator interface, an interval fold through every converter and modifier, interval arithmetic down into the noise primitives themselves (gradient corners, warp, worm frequencies), and a BlockSkip lattice the mesher consults per 8^3 block. Its own guiding comment, which is the right default: "no finite interval is a proof. Unknown costs the skip and protects the geometry." 128^3 TunnelNetwork seed 1337 slot 1, freshly built binary, 3 runs each: before 1.515 / 1.554 / 1.569 s after 1.213 / 1.258 / 1.171 s -22.5%, 1.28x -- clears the 17% floor Geometry SHA-256 98eaad61..d3c4f IDENTICAL to0e9df9e. 153,740 triangles either way. It skips only provably-empty work; nothing about the world changed. It also fixed one cause of the 5.6 s empty tiles found in0e9df9e: an LOD4 tile legitimately spans 19^3 = 6,859 chunk keys and was rebuilding per-chunk state thousands of times within a single tile. A shared cache removed that failure mode; remaining slow empties were LOD0 and are a separate fast-classifier bail, still open. Partially landed, unfinished when killed: RequestStartCycles on FChunkResult, to report request-to-ready latency rather than worker generation time. Harmless as is. ⚠️ WHAT KILLED IT, AND IT IS OURS A single UnrealEditor-Cmd commandlet grew to 19.5 GB, leaving 1.3 GB free on a 32 GB machine, and the OS killed the agent. Freeing it restored 21.6 GB. The owner said twice that his machine should not be under memory pressure and he was right both times: first the 411 MiB worker caches, now a 19.5 GB commandlet. A generation run must not need 19.5 GB. Next task. Cumulative on this region: 342.2 -> 16.2 -> 2.62 -> 1.49 -> 1.21 s (~283x). 3,374 insertions / 342 deletions across 12 files. Build 0 errors. Nothing outside Plugins/VoxelForge; RealtimeMeshComponent untouched. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012aheo2crrZmHuYtPpdY2Cb
