Game process (ARAM Hexgate: 84 -> 127 FPS average, slowest stretches ~110): - Local pthread mutexes, condition variables and Mach semaphores are on by default in the game process only, with /tmp/rclol-no-local-* opt-outs. The main thread's darlingserver waits fell from 1.36 to 0.10 ms per frame. - Local semaphores: the count and the slot generation change in one compare-exchange, a destroy leaves a negative marker, the table is reset after fork, and names the table did not create go to the server. - Metal: drop identical re-binds (keyed on the Indium object, depth-stencil retained), pass blit resources by reference, and stop resetting vertex descriptors twice. - Core isolation of the main thread is opt-in (/tmp/rclol-core-isolation); it lowered FPS in its only match. - Optimized libc/libc++/Foundation overlays, AVX2 string primitives, real CPU topology and their installers and offline checks. Tools and docs: - tools/riot-match-capture: passive /proc sampler, user-space IP profiler and reports, plus a comparison against the game's netstats. - tools/riot-lsem-model and tools/riot-metal-bind-model: host models that extract the shipped code and check it. - tools/install-riot-metal-pair.sh installs Metal and Indium together. - Status, setup, testing and troubleshooting docs updated with the measured matches and the switch table; manifest file counts match the patches.
