pub const OUTBOX: &str = "outbox";Expand description
Durable reliable-messaging outbox backing vti_common::outbox_store::
VtiOutboxStore for the delivery-layer MessagingService (D2 P2a
cut-over). Holds Guaranteed-delivery outbox entries; dormant in P2a (all
current sends are BestEffort) but wired so the drain/confirmation loops
persist across restarts once P2b adds guaranteed VTA pushes. Runtime state,
not backed up.
