L86's switch left ApplyResolvedStratePassageCarves running (near-tile service unchanged at ~21
worker-s), so its "no change" ceiling was wrong. Corrected (bands + carves off): FI LOD0-2
2.34 -> 0.66 s, whole 3.47 -> 1.49 s @W12; TN 2.27 -> 0.74 / 3.28 -> 1.52 s. Near-tile service
15.6-22.5 -> 2.6-3.8 worker-s. Critical chain: shape/base compile -> LOD0-1 -> far-parent build
(107-153 ms, pipeline thread) -> LOD2. Workers 81-85% busy in the direct window.
No production scheduling change; hashes equal L85. Fast tier PASS.
