The harness runs the whole lan_e2e suite: ~40 minutes on a loaded runner,
and single checks flake under load (barter, riding, shulker_bullets in one
run; cursor, falling in another, all passing on rerun). Selected by
--changed it would run on most gameplay pull requests and on parity-main.
tools/parity_hosts.json gains a named_only table that every automatic
selection (--changed, --failed, the default, --flake-check) leaves out;
naming the harness or --all (the nightly audit) still runs it.

Ludovic's rule (2026-10-26): runner_pause.py pauses at once on keyboard, mouse or gamepad input
(read from /dev/input, only whether bytes came), on an unlocked session touched in the last
15 min, at 90 °C, on a game or the GPU. Fixes the service start: the link loop's last test
failed the script under set -e.

runner_pause.py pauses on any seat0 session (locked too), games, GPU use or a pause file, and is
the only thing that starts the runner; a job under way is throttled, then the runner stops. The
desktop host in parity_hosts.json refuses work while paused and its workers stop on a pause. The
nightly audit stays on the Mac mini. Docs and a unit test of the watcher.

On macOS the Horizon client renders offscreen (--offscreen) with audio off,
from the logged-in session; Linux keeps vscreen and the null ALSA device.
The vanilla side was already a headless dedicated server. --bin-dir is
resolved, since the client runs from the run folder. parity.py no longer
skips save_roundtrip off Linux; it stays local-only (no rendering over SSH).

The first audit on the Mac mini failed 7 audio harnesses (no sounds in the prepared resources: the Mac mini has
no official launcher for horizon-prepare sounds to copy from) and save_roundtrip (it needs vscreen). The
sounds depend only on the Minecraft version: kept once in shared-local/sounds/<version>/ and linked into each
preparation.

particles, the warden's and brains' weighted shuffles.

The Mac mini and ThinkPad no longer keep the shared vanilla data, so the
other machines are opt-in again.

Number the server files cases, whose folders eula-true and eula-TRUE collide
on case-insensitive macOS file systems; keep world_border_render and mob_ai
off the Mac, where platform float math changes their results; give the local
executor the dead flag the flake check reads.

A sample of 27 harnesses (the 20 quickest, options, datafix's six shards)
passed there; it builds against the same ALSA headers as the desktop.

Every harness gave the same result on the Mac mini as on Linux, except
options and chunk_generation, where Rust's float functions use the platform
libm and round differently on macOS: those stay off the Mac. gate.py and
supervise.py no longer force 8 local harnesses, so parity.py keeps the
desktop to 3. The ThinkPad is listed (2 harnesses, nice 19) but not used by
default. Oracle runs get a 15-minute hang guard instead of 5, since one oracle
on a fully loaded machine can take more than 5 minutes.

A worker started over ssh (parity.py --worker) runs harnesses on a mirror of
the worktree on another machine, here the Mac mini. One longest-first queue
feeds every machine, remote ones first; passes come back with the content
hash of each dependency, so they are keyed on exactly what ran. Harnesses
that need this machine are listed in tools/parity_hosts.json.
