Research status: Completed after 4 of 6 allowed iterations (status=done). This report synthesizes those passes. It is not a claim of exhaustive coverage of every agency OS or every experiment in the literature; open gaps are listed explicitly.
Purpose: Specs and operating logic for an autonomous open-source SEO skill—not a generic marketing guide.
Evidence tags used throughout:
- [E] Established — Google/Bing primary docs or controlled experiment platforms with transparent method
- [P] Practitioner consensus — respected operators/agencies, repeated independently
- [H] Hypothesis / skill default — reasonable synthesis where standards don’t exist
