Every ECHO object a qualified path could be asking about, terminal segment first.
The weaker question than tryGetEid's "which object IS this node", which must stay strictly
terminal because it backs plank dedup — two views of one object are deliberately two planks. A node
addressed by a view discriminator (sent, drafts) carries its object id in an interior segment,
so an existence check that demands the terminal one 404s it.
