tests/__init__.py keeps a run offline, its scratch under tmp/ and its
installer cache its own, but only discover -s tests -t . imported it.
discover tests ran with RETROBIOS_OFFLINE unset, scratch on the /tmp
tmpfs and the user's real installer cache, the setting in which e2e
fixtures had written into the shared .cache/large. Every test module now
imports the package first, and a test fails on a module that does not.
test_verify_listing.py took its line with the previous commit.
--all --system built every pack asked for and exited 1 on a platform
that has no such system. The scope is now decided before the lock:
skipped under --all, refused under --platform (finding 15).
A system the target leaves no core for was verified 0/0 with exit 0,
and generate_pack blamed the platform for lacking it. Both read
platform_scope_systems and system_scope_error now (findings 13, 14).
A platform without hardware targets is now left out of a targeted --all run instead of being built unfiltered, and a run no platform can honour is refused.
