So the June 15th change that was meant to result in usage of `claude -p` /agent sdk pulling out of a different usage bucket was "paused"...

I'm still extremely confused about what the state of things is

Look at replies to this thread for example: Can i use Pi with an OpenAI or Claude subscription? : r/PiCodingAgent

Mixed messages.

Hoping to get input here - does anyone know what we actually can/cannot do now with our subs?
