AnnouncementDepositInvariantViolated

A chain-side invariant failed; nothing to fix client-side — report it if it persists

Internal invariant failure in announce: recomputing the announcement deposit returned nothing after the pending announcements were updated. Inspect the caller's Announcements entry and the announcement deposit constants; this indicates a pallet bug rather than bad input.

Declared by the Proxy pallet; it classifies to the semantic code internal.
