async fn move_block_references(

writes: &StagedWrites<'_>,
) -> ModelResult<()>Expand description
Points feedback and edit proposals at the page their blocks moved to.
A record moves only when none of its blocks is left on its page; it then follows its first
block that still exists. Blocks keep their clientId when moved, so only pages in the
changeset can have gained or lost them.
