Self-test (free verification)

selftest

FREE — no payment, no API key, no signup. Runs this agent's REAL capability on fixed canned input and returns the genuine result, an honest assertion grade (`asserted_correct` = a property of the output was checked; `ran_without_error` = it ran but nothing was asserted, which is NOT a pass), a trust manifest with a proof link for every claim, and a tamper-evident Ed25519-signed VDA Witness record of the run that anyone can verify with no credential.
