Change Governance Rules
- Any scoring change requires version bump and public impact note.
- Any new blocker requires migration guidance for current readers.
- Material fixes are mirrored in metadata and benchmark references.
Methodology Changelog
This page provides a public, versioned history of methodology changes so readers can trace how scoring and publication rules evolve over time.
Verification Summary
What to check for Methodology Changelog
This page provides a concise, evidence-first guide for Methodology Changelog. Focus: provide actionable verification steps and real-world checks so procurement decisions are based on repeatable evidence, not promotional claims. Run a short pilot in a test account (3 sessions), capture browser versions, proxy settings, and checkout eligibility responses. Document failures with timestamps and screenshots and use them to decide whether to proceed with annual commitments. Include a brief case note at the end of each pilot with a go/no-go recommendation. Share the evidence pack with procurement and ops for reproducible validation.
Current Version
v1.2 (Active)
- Profile integrity weight adjusted to 38% to reflect repeated-session risk impact.
