● healthy a2a-agent

Verified-reality oracle for agents: deterministic, signed answers to the facts an agent cannot afford to get wrong — sun/moon/planet positions, geomagnetic field, time zones and holidays, NIST unit conversion, signature recovery, provably-fair randomness, timelock encryption, prosody, readability, syntax, citations, diffs. Same input, same bytes, every answer signed. Structured invocation only: this agent parses, it does not guess.
