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

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.

A pass is keyed by the content of the harness's dependencies, so it is
also valid in any worktree with the same files. Passes are published to
parity-shared/ beside the shared vanilla data, and a worktree adopts one
whose key matches its own files instead of running the harness: an
agent's gate only runs what its own changes affect, instead of the whole
suite from scratch. Every runner on the machine also shares
PARITY_MACHINE_JOBS slots, so several agents' gates can't overload it.

tools/parity_shim.py stands in for java and javac in harness runs: it
records each oracle run's outputs and the content of every file under the
paths its arguments name, and replays the run while those are unchanged.
After a Rust-only change a harness only pays for its Rust side
(block_update 53 s -> 5 s). A harness that fails while reusing oracle
results is rerun fresh, and stops reusing them if that passes; --all and
--fresh never reuse them.
Harness probes built in the dev profile are optimised (overflow checks
and debug assertions kept), and the chunk generation harness runs its
vanilla and Horizon sides concurrently.
HORIZON_NO_AUDIO keeps the game off the speakers; tools/parity.py sets it,
since the save round-trip harness launches the game on a virtual screen.

tools/parity.py traces each harness (its Python, Java oracle sources and
the Rust sources of the probes it runs, from Cargo's dep-info) and reruns
it only when one of those, the vanilla artifacts or the toolchains change.
Harnesses run in parallel within the available memory, and their probes
build without LTO and with 16 codegen units into .local/parity-target: a
one-line change rebuilds every horizon-world probe in 3 seconds instead of
122. The full suite takes about 20 minutes instead of an hour.
tools/gate.py is the check a branch passes before integration, and
tools/supervise.py manages the per-area worktrees: status, new worktrees,
saving unfinished work, and integrating a branch only when the gate passes.
Harnesses find probes through lab.cargo_target() instead of a hard-coded
target/, the save round-trip harness builds the binaries it launches, and
the mob AI harness now fails on divergences like every other harness
(--report-only keeps the old behaviour). Debug builds keep line tables
only, so worktrees stay small.
