Struct IssueGrantAndClaimArgs 

#[non_exhaustive]
pub struct IssueGrantAndClaimArgs {
    pub execution_id: ExecutionId,
    pub lane_id: LaneId,
    pub lease_duration_ms: u64,
}

Args for crate::engine_backend::EngineBackend::issue_grant_and_claim.

Composes issue_claim_grant + claim_execution into a single backend-atomic op per cairn #454 Q4. The composition must be backend-atomic (not caller-chained) to prevent leaking grants when claim_execution fails after issue_claim_grant succeeded.

Valkey: one ff_issue_grant_and_claim FCALL composing the two primitives in Lua. Postgres/SQLite: both primitives inside one tx.

Flattened shape (not IssueClaimGrantArgs + ClaimExecutionArgs composition) — the two arg types overlap on execution_id + lane_id; flattening drops the dup.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

execution_id: ExecutionId

lane_id: LaneId

lease_duration_ms: u64

Lease TTL in milliseconds. Threaded into both the grant TTL and the claimed attempt’s lease_expires_at_ms.
