WalkthroughAdds a disposable Fly tiny-environment qualification harness with admission checks, immutable image provisioning, Machine validation, smoke evidence retrieval, atomic resource tracking, fail-closed teardown, CLI execution, and comprehensive tests. Fly adapter provisioning also disables snapshots and enables automatic Machine removal. ChangesFly tiny qualification
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new live qualification executor can crash on malformed Machine state and omit its sanitized result, preventing reliable qualification outcomes; merge should wait until those responses are converted into the existing failure path.

- Around line 353-368: Update the Machine state validation condition in the
qualification flow to safely handle a null or non-dict restart value and a
non-dict first mount entry, ensuring both cases evaluate as mismatches and raise
the existing typed QualificationError with “provision_failed” rather than
AttributeError. Preserve the current validation behavior for valid dictionaries.
