Round 3 supplemental run ledger (2026-10-10):
PASS: M1 SurfaceWorld BuildHost after restoring the original 32-voxel mapping and 4.0 edge threshold; original worker hash preserved.
PASS: M2 HybridV1 and HybridV2 BuildHost fixtures.
PASS: M3 floating-island BuildHost on the root-parameter-cache source state; see m3_floating_islands_buildhost.*. Peak observed process memory about 3.44 GB. Tile hashes, coverage/LOD, collision/capsule contact, content anchors, height/strate/atmosphere/water agreement, Blueprint carve/fill, W1/W8/W16, and Core-off legacy checks passed.
PASS: Instrumented M3 commandlet after the root-cache change printed PASS and pass-complete=1; wrapper exited 1 because console-title channel failed with 0xE9. Timings are in REPORT.md. This is recorded as a wrapper failure as well as an internal commandlet pass.
FAIL: Island fixture attempts in order: desired tiles 2227/2553 (route player absent); origin pawn from GameMode; 2557 desired tiles after possession (dynamic collision support); support tile-key mismatch; collision gate off restored 2553 but hash differed at (-2,0,-31); CreateLocalPlayer(true) hung and was manually stopped after ~3–4 minutes; base UPlayer fixture lacked controller registration/root transform and failed preflight after 5:10. Corrected explicit controller/root/location fixture passed.
FAIL: M1 edge-threshold experiments: 4.0 -> 52075.827 > 51200 at LOD8 tile (2,0,-1); 4.125 -> 53960.427 > 52800; 4.25 -> 54806.919 > 54400; 4.5 passed edge bounds but yielded no full-span LOD0 candidate. Restoring the correct split chunk mapping and baseline 4.0 threshold passed.
FAIL: Earlier compile errors were corrected: DuplicateObject overload, private helper access, unresolved GetEffectiveWorldSeed export, and uint32-to-int32 narrowing. Initial standalone invocation with -Workers failed; -CompileWorkers 4 succeeded.
RETRY/ENVIRONMENT: One requested retry followed a 0xC0000142 shell-start failure; additional PowerShell/cmd inspection launches also failed with 0xC0000142. No subsequent BuildHost attempt was made. No 0xC0000142 BuildHost retry occurred during the completed runs.
CRASH CHECK: No new UECC-* folder reported; only historical folders dated 2026-09-17 and 2026-10-08. The CreateLocalPlayer hang was manually stopped, not a crash. Latest BuildHost test peak was below 4 GB; all completed test/build steps stayed within 15 minutes.
CURRENT TREE CAVEAT: XY-column cache was edited after the passing/profiled BuildHost run. It remains uncompiled and unmeasured due shell startup failures; current tree is not verified until that edit is built/tested or reverted.
