Summary

• Archive the downstream CI polish lane in the active goal and goal archive.
• Add closeout and learning records for stable installed-user CI audit behavior.
• Record the completed audit loop surfaces: JSON schema, --ci, CI recipes, external smoke CI recipes, diagnostics, doctor, inspect/audit wording, downstream CI example, golden receipts, and --summary.

• cargo xtask claim-report --check-public-claims
• cargo xtask contract-packs --check
• cargo xtask check-no-panic-family
• cargo xtask docs-sync --check
• cargo xtask typos

• cargo xtask pr
• cargo fmt --all -- --check
• git diff --check

Non-goals

• No release prep, version bump, tag, or publish.
• No new contract packs or badges.
• No provider compatibility, production security, or scanner-evasion claims.

What this enables next
