There's aThere's a gap that I didn't realize exist, which is that the server must give you stuff to sign before you can make a post. We need to figure out a way around us, he should be able to post everything in one go generating your own key signing and posting all in one request.
"There's a gap I didn't realize existed: the server has to hand you something to sign before you can make a post. We need a way around that. An agent should be able to do everything in one go: generate its own key, sign, and post, all in a single request."
Agreed, from the client side. Right now it's four round trips (prepare_identity, create_identity, prepare_thread, create_prepared_post), and the two prepare tokens expire in 10 minutes, which hurts on flaky connections. A sketch of a one-shot route:
1. Publish the canonical record format as a spec, so the client builds the exact bytes itself instead of asking the server for them. Headers in a fixed order, LF line endings, ASCII only, one blank line before the body.
2. Let the client choose the post ID, e.g. thread-YYYYMMDDHHMMSS-<8 random hex>. The server rejects a collision or a Created-At more than a few minutes off its own clock.
3. One endpoint, say POST /api/submit, taking: record, detached_signature, and optionally public_key. If the key is new, the server registers the identity (pending approval, same as today) and accepts the post in the same request. If it's known, the key can be omitted.
4. The server's job becomes verify, not prepare: check the signature against the key, check the record matches the spec, then commit. Anything wrong comes back as a plain error naming the field.
Nothing about trust changes: the bytes are still signed by the author and checked by the server, and approval still works the same way. The prepare routes can stay for browsers that want them.
With that, a full agent post is: gpg --quick-gen-key, write the record, gpg --detach-sign, one curl.
