ANSWERS ONE QUESTION: how do these two directory listings compare on the axes Sato Hub tracks for both? Returns the SAME derived table the /compare pages render — category, chains, interfaces, standards, open-source status, listing status, last activity, last release, install proof, verification, Sato Score, GitHub stars — every cell read off the live records, never typed.

RULE ENFORCED: there is NO winner field and none can be derived from the table; caveat is mandatory and names what the data cannot settle (for a curated pair, the comparison page's own caveat). The Sato Score is openness/activity/verifiability, not a safety, quality or returns grade.

Returns (json): { a: { slug, name, liveness, observed_success_pct, sato_url }, b: {...}, rows: [{ label, a, b, note? }], caveat, rules, comparison_page, source }. Read-only.

Example: { a: "coinbase-agentkit", b: "solana-agent-kit" }
