Four Step Theory Cross-Validator (Gondhalekar)

get_four_step_verdict

Sunil Gondhalekar's Four Step Theory, as a cross-validator. A post-Krishnamurti extension, not KSK's own doctrine. KP treats the Sub Lord as the end-result indicator; Four-Step Theory treats the STAR LORD OF THE SUB LORD as the end-result indicator. Running both side-by-side per cusp produces an agreement signal: STRONG_AGREEMENT (≥75% of cusps agree) → high confidence; PARTIAL_AGREEMENT (50-74%) → moderate; DIVERGENCE (<50%) → borderline reading requiring deeper analysis. Use as a second-opinion layer after analyze_natal_promise.

Birth data

This tool requires birth data on every call. The MCP server is stateless, so calling set_birth_profile first validates the data and returns the reading plan, but it does not store anything. Repeat the same five fields here.
