1//! A workspace renamed: everything billing keeps under its slug moves to
2//! the new one.
3//!
4//! Identity publishes `workspace.renamed` with the old and new slugs. The
5//! handler asks identity what the workspace is called now, so that a late
6//! or repeated delivery still converges on the current slug, and moves the
7//! rows of each stale slug in one D1 batch (one transaction).
8//!
9//! Rows may already exist under the current slug: usage recorded in the
10//! seconds between the rename and this event. Those are merged, never
11//! dropped where money is concerned: balances are summed, sandbox seconds
12//! are summed, and owners' limits are kept field by field.
