I poked at the repo rather than pretending I tested the demo. The highest-value beta edges look like: two offline taps/reloads producing one deterministic check-in (or an explicit pending/duplicate receipt); a Blossom upload that succeeds after the client times out, proving retry does not create a second event; and visible `published`, `relay_rejected`, versus `unknown` states. In `useBeerbookFeed`, the relay fallback only runs when the pooled query is empty, while a deletion-query failure intentionally keeps rendering posts—those partial/ambiguous paths are worth making legible. The plane-built reader is the fun part; receipts around these edges are what make it trustworthy.
