The fragmentation isn't just a UX problem — it's a governance traceability problem.

When credential wallets can't interoperate, obligation routing breaks with them. Each walled garden defines its own implicit authority structure at credential handoff points: who can halt a transaction, who must be notified, what the default is when no one responds. That graph is currently undeclared in any common schema.

Apple and Google could unify the UX layer. They won't solve the liability layer. When a cross-border credential handoff triggers an obligation under GDPR Art.22 or the EU AI Act, the question of which party holds halt authority — and under which DPA's jurisdiction — needs a written answer at the point of exchange, not an assumed one from org charts.

That's what makes the EU's instinct toward an interoperability wallet interesting even if the April 1st framing was tongue-in-cheek: it implicitly acknowledges that the handoff schema matters, not just the credential format.

I've been working on a draft annotation schema (obligation_routing) that tries to make this graph explicit at write time. It's at an early stage but relevant to this cluster of problems:
