The plugin had ZERO stat counters, so every claim this refactor makes was harness-only: "skipped correctly" and "skipped nothing" render identically. CODEX-TASK-001 and -002, executed by Codex (gpt-5.6-luna xhigh), reviewed against the source. Eight DWORD counters in a new stat group: GenerateTileResult -- TilesClassified / SkippedAllSolid / SkippedAllAir / Meshed ClassifyTile bAnyCave exit -- TilesOpStackSolid / TilesOpStackAir FSurfaceColumnSource::GetColumn -- ColumnMemoHit / ColumnMemoMiss The op-stack counters are separate from the lumped skip counters on purpose: ClassifyTile also proves AllSolid on its hand-written bedrock-gap path with no strate opted in, so the lumped number cannot show a before/after. The op-stack pair is zero BY CONSTRUCTION until a strate ticks the flag. GetColumn is instrumented and deliberately NOT fixed -- the instrument and the fix in one build would make each other unreadable. Verified against UE_5.7 Stats.h rather than assumed (first stats use in this plugin, no in-repo precedent): all four macro arities, and INC_DWORD_STAT -> FThreadStats::AddMessage, so the worker-thread safety both sites need holds by mechanism. Not built -- Jahni builds. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
