fn latest(env: soroban_sdk::Env, asset: soroban_sdk::Symbol) -> Optionfn quorum(env: soroban_sdk::Env) -> (u32, u32)Required by StellarHandlerInterface — project-root uses this to
recognise the contract as a handler.
fn payload(

event_id: soroban_sdk::BytesN<20>,
) -> Optionfn request(env: soroban_sdk::Env, request_id: u64) -> Optionfn final_twap(env: soroban_sdk::Env, request_id: u64) -> OptionStellarHandlerInterface::verify_xlm — the single entry the
warpdrive node's submission manager invokes for every
aggregated submission against this handler. The envelope payload
is a tagged SubmissionPayload whose variant decides whether
this is a Round 2 single-Vectr attestation or a Round 3
quorum-signed final.
Both variants go through the same try_verify call (the
quorum is global to the security contract; with a single
operator at 1/1, one sig satisfies it; with N at 4/5, Round 2
payloads need their event_id_salt to be unique per Vectr so
the host doesn't try to quorum-collapse different-value
attestations).

range_secs. Returns the request id (clients store it to poll
for the final result via final_twap(id)).
fn request_twap(
