Manual Review Checklist

• Verify source references are enough for every architecture finding.
• Verify vendor-specific behavior has not been flattened.
• Verify recursive self-adaptation impact is handled or explicitly blocked.
• Verify tests, docs, examples, and migration notes match public API changes.
• Confirm no auto-merge or unsupported credential scraping was used.

Safety

• Draft PR only.
• No auto-merge.
• Local credentials are not scraped.
