…t (Phase 1) - SX_SERIAL_LAUNCH=1 boots the Xfce clients strictly one at a time (each gated on becoming active then settling for SX_SERIAL_SETTLE_MS, default 12s, with a per-app timeout safety cap), removing the concurrent-boot CPU/thread oversubscription that flakily blanked the desktop. - Measured: 5/5 FULL renders (95-99.9% coverage), ~61s, zero total-black, vs ~1/3 concurrent. Confirms concurrency as the flaky-black root; determinism (Phase 1) achieved. See DESKTOP-BOOT-PERF.md.
…r (per-app init dominates); real levers = cap concurrent compile / batch launch / trim dbus sleeps
…t 94% idle (1.17/20 cores); serialized not blocked; concurrency is the speed win, compile-burst is the flakiness

Experiment under
experiments/wasm-gui/: a graphical Linux desktop built by cross-compiling real, standard X11 software towasm32-wasip1with our own toolchain and running it inside the real secure-exec V8 sidecar, rendered by a native Rust app oncrates/secure-exec-client(per SPEC §1a: no wasmer / node:wasi / TS client /Command::newin the execute+render path).What works (all wasm guests in one VM, over host_net AF_UNIX)

net.pollblocked the single service thread up to 50ms, starving other guests; lowered to 3ms so it round-robins.limits.resources.maxWasmFuel.Notes
