Problem: green PR checks could omit complete isolation/worktree owner tests on
Windows and under Linux race; pure isolation changes could skip native legs.
Root cause: the smoke and race package allowlists lacked both owners, while
the platform classifier treated untagged isolation Go as neutral.
Fix: classify isolation paths as platform-relevant; execute complete Windows
owners with an uploaded JSON inventory, require both package terminals and
portable boundary tests, and include both packages in PR race. Replace the
redundant rollback subset. Preserve existing permissions, deadlines and cache
rules; do not alter product code.
Verification: compiling old-workflow/classifier regressions, exact inventory
positive/negative controls, final classifier/testenv suites, complete 238-package
root inventory, three-owner race, required builtin/boot, vet, lint and check.
Local execution is macOS; native hosted outcomes remain a separate gate.
