# title
DF-VERIFY/1 — attestation/v1 profile (parametric trigger)

# description
A signed, tamper-evident record that a parametric trigger ('metric op threshold' at a location) was MET or NOT MET against the live measurement at issued_at. Detached Ed25519 signature over the object minus its `signature`, json-sorted-compact. The dispute-proof oracle a parametric-insurance payout settles against.
