Existing live route unchanged.

Check up to 32 JSON argument values against a closed, declared scalar tool contract: types, required fields, code-point length and exact safe-integer bounds. Rounded fractions/underflow are not integers. Returns unknown fields and mismatches. No remote references, arbitrary patterns, tool execution or MCP conformance certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check a supplied single-qubit complex density matrix for unit trace, Hermiticity and positive semidefiniteness with explicit tolerance; no hardware validation. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

For agents reviewing shot-count results: return probabilities and binomial confidence intervals with the interval method and independence assumptions. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Evaluate up to 64 explicitly fictional strategy/game choices against caller-declared integer utilities. Reports best declared actions, chosen utility, regret and observed-minus-declared error. No hindsight counterfactual outcome inference, financial advice, real-world intelligence assessment or strategy fitness claim. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Compare up to 64 proposed Base-USDC calls with a declared total budget, per-call cap, allowed payees and human-approval requirement. Returns policy mismatches and exact arithmetic totals. Does not authorize, sign or execute payments; caller approval labels are not verified. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Verify one Ed25519 signature over up to 8,000 characters of exact UTF-8 receipt text using a supplied 32-byte public key. Returns cryptographic validity and message hash.
