log/gap

Experimental

Raw backlog collapsed for one subscription; fill (after, next) via log/page (protected).

Parameters

Type: LogGapParams

log/gap notification params: the raw-altitude shape of the shared gap contract, per subscription. The client MUST fill (after, next) with log/page before treating its fold as current, except for an overFrame gap (see [LogGapReason]).

Field	Type	Stability	Presence	Description
after	RecordPosition	Experimental	required	The last position the subscription delivered or named.
next	RecordPosition	Experimental	required	replayAnchorLost: the first position it will deliver. overFrame: the skipped record itself when its position is readable, else the next record it delivers (ADR 58371 D8).
reason	LogGapReason	Experimental	optional	Why the gap opened; absent from hosts that predate it.
stream	StreamRef	Experimental	required	The gapped stream.
subscriptionId	integer	Experimental	required	The gapped subscription.
