Struct DeliverApprovalSignalArgs 

#[non_exhaustive]
pub struct DeliverApprovalSignalArgs {
    pub execution_id: ExecutionId,
    pub lane_id: LaneId,
    pub waitpoint_id: WaitpointId,
    pub signal_name: String,
    pub idempotency_suffix: String,
    pub signal_dedup_ttl_ms: u64,
    pub maxlen: Option<u64>,
    pub max_signals_per_execution: Option<u64>,
}

Args for crate::engine_backend::EngineBackend::deliver_approval_signal.

Pre-shaped variant of crate::engine_backend::EngineBackend::deliver_signal for the operator-driven approval flow. Distinct from deliver_signal because the caller does not carry the waitpoint token — the backend reads the token from ff_waitpoint_pending (via crate::engine_backend::EngineBackend::read_waitpoint_token, #434-shipped in v0.12), HMAC-verifies server-side, and dispatches. The operator API never handles the token bytes.

signal_name is a flat string ("approved" / "rejected" by convention; not an enum at the trait level — audit metadata like decided_by / note / reason sits in cairn’s audit log, not in the FF signal surface).

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

waitpoint_id: WaitpointId

signal_name: String

Conventional values: "approved" / "rejected". Stored raw on the delivered signal; FF does not interpret.

idempotency_suffix: String

Cairn-side per-decision idempotency suffix. Combined with execution_id + signal_name to form the dedup key.

signal_dedup_ttl_ms: u64

Dedup TTL in milliseconds.

maxlen: Option<u64>

Signal stream MAXLEN for the suspension stream. None ⇒ backend default (matches DeliverSignalArgs::signal_maxlen).

max_signals_per_execution: Option<u64>

Per-execution max signal cap (operator quota). None ⇒ backend default (matches DeliverSignalArgs::max_signals_per_execution).
