Construction failure for a participant-scoped nonzero-debt episode.

Variants

DuplicateParticipant

Two cursor states name the same permanent participant identifier/index.

Fields

participant_id: ParticipantId

Repeated permanent participant identifier and index.

ObserverBeyondHighWatermark

Hard observer progress cannot be beyond the candidate watermark.

Fields

observer_progress: DeliverySeq

Durable observer progress.

candidate_high_watermark: DeliverySeq

Candidate high watermark H'.

CursorBeyondHighWatermark

A bound cursor cannot acknowledge beyond the candidate watermark.

Fields

participant_id: ParticipantId

Permanent participant identifier/index.

cursor: DeliverySeq

Durable participant cursor.

candidate_high_watermark: DeliverySeq

Candidate high watermark H'.

FloorBeyondRetainedEnd

The supplied first-retained floor is beyond checked H' + 1.

Fields

current_floor: u128

Supplied current floor F.

retained_end: u128

Checked one-past retained end H' + 1.

CapacityFloorBelowBase

The append-free ack envelope selected a floor below the actual base.

Fields

cap_floor: u128

Supplied committing-class cap_floor.

base_floor: u128

max(F, preferred_floor) for the initial episode state.

CapacityFloorBeyondObserver

The supplied capacity floor would overtake hard observer retention.

Fields

cap_floor: u128

Supplied committing-class cap_floor.

observer_limit: u128

Greatest floor allowed by hard observer retention, o + 1.
