Struct PendingFrame 

struct PendingFrame {
    frame: HostFrame,
    saga_id: Option<u64>,
}

One frame waiting to be written to the host. Tracks the saga_id when known so we can emit a meaningful SagaFailed if the frame is dropped on overflow / timeout.

Fields

frame: HostFrame

saga_id: Option<u64>

Some(id) for Command frames whose Command variant carries a saga_id. None for Event frames (the host is not the only subscriber for events — they also flow to the renderer / Tool clients via the broadcast bus, so a missed event-frame is not a saga-level failure) and for Command frames whose variant has no saga_id field yet (the schema additions land in CPD-1).

Trait Implementations
