Without a BIOS, PCSX2 logs and shows 'PCSX2 requires a PlayStation 2 BIOS in order to run'. That line is now one of PCSX2's error patterns, for the next run's verdict: this record was judged without it.
standalone_probe now holds the host probe lock for one run, its load check included, as core_probe does, and the docs no longer wrap region_check or standalone_probe in flock.
PCSX2 writes its NVRAM and MEC files beside the BIOS and reported an error on the read-only folder, and both emulators opened an error dialog over the screen for want of a sound device. The BIOS folder is now writable and staged again for each repetition, and both use the null audio backend.
The new probes now refuse abbreviated options, read the GitHub token through github_headers, type every signature and document every option. The site build watches region_check.py and the content list, and validate.yml's tests/** counts as watching the list. The testing guide names the two new test modules.
standalone_probe.py runs the release binary a platform installs (EmuDeck's asset rule for DuckStation and PCSX2), unpacked without running the AppImage runtime, in core_probe's allowlist sandbox with a private Xvfb, strace and core_probe's oracle and record functions. Records go to measurements/<emulator>.jsonl.
