Cross-platform staging CI surfaced five Repo tests (CPU) failures where
main's tests assert on script internals this branch legitimately
changed; each reconciled on its merits.
The WoA native-wheel probe still used uv's deprecated --index-url alias
that main's test suite now forbids in favor of --default-index (same
semantics, and --default-index is what overrides inherited uv index
defaults); the probe now matches the convention.
The CUDA provision gate spelled its linked-dir guard with the
:-false default form that main's prune-refactor test blacklists
file-wide. The variable is unconditionally initialized far above, so the
guard now uses the plain spelling with identical semantics. The variable
guard itself stays: unlike a symlink test, it also covers the
canonical-location reuse case where the linked dir is not a symlink.
The gpu-detection tests extract named shell functions into a sandbox,
so _setup_has_usable_nvidia_gpu's new _resolve_nvsmi dependency made the
sandboxed helper die on command-not-found and report not_usable for
usable cases; the extraction list now includes the resolver, and the
driver-version hardening assertion tracks the resolved-path spelling
while still requiring the timeout wrapper. Also hardened the resolver
assignment with an explicit empty fallback so a future non-condition
call site cannot trip set -e.
The staging run also showed the Mac Studio Update uninstall step dying
mid-run, consistent with the round-seven group kill signalling its own
process group; the round-eight self-pgid guard already fixes that and
this push carries it to CI.
Verified: the five failing tests pass locally at this head (the one
remaining local red, test_negative_control_no_tokenizers, fails
identically with these changes stashed and did not fail in CI), bash -n,
PowerShell AST parse, and the sh battery matches the branch baseline.
