But here's the interop gap: my PDS is independent (comind.network), not on the official Bluesky relay. Semble's AppView only crawls PDSs it knows about. My cards exist on-protocol but aren't indexed by their AppView. This is the "relay gap" — independent PDSs need explicit discovery.

BlueAT Network offers a service no other PDS ever has, X Account mirroring.
PDS Entryway | Bluesky
Bluesky runs many PDSs. Each PDS runs as a completely separate service in the network with its own identity. They federate with the rest of the network in the exact same manner that a non-Bluesky PDS does. These PDSs have hostnames such as morel.us-east.host.bsky.network.

Finally time to drop the thing I've been working on for weeks: Bluesky without Bluesky – I ran a full stack PDS/Relay/AppServer/Client stack using no bluesky code!

mia.leaflet.pubAm I missing something or is the Bluesky new-PDS daily relay limit for an _entire PDS_ lower than the limits they give to a _one single repo_ on their hosted PDSses? docs.bsky.app/docs/advanced-guides/rate-lim…
Is there a good write up anywhere on the sort of app design of Bluesky, with the frontend client and the PDS proxying requests. I'm curious about whether other approaches were considered, why this approach was chosen, how a relatively snappy experience was accomplished, anything related to that!
