G009 Stream 8 acceptance requires a Windows release artifact quickstart with checksum evidence, not just source-build docs. Add Windows release asset packaging and make the release-readiness check assert the workflow/docs contract.
Constraint: Stream 8 requires release artifact quickstart with checksums and no-credential smoke paths.
Rejected: Documenting a future Windows asset without workflow support | would leave acceptance unverifiable.
Confidence: high
Scope-risk: narrow
Tested: python3 .github/scripts/check_release_readiness.py; python3 .github/scripts/check_doc_source_of_truth.py; git diff --check
Not-tested: actual GitHub release workflow execution on windows-latest.
