Another curious #ActivityPub / #MastodonAPI issue.
A Mastodon server is sending me a DELETE message.
The delete is because a user has been deleted.
My server tries to validate the HTTP Signature.
My server looks up the deleted user's main-key.
The user has been deleted so the public key 404s.
My server never acknowledges the delete, so the other server keeps sending me the same request.
So… How do I validate the signature of a deleted user?

The commissioned work focuses on improving developer experience, adding comprehensive debugging tools, and ensuring Fedify remains at the forefront of #ActivityPub innovation.
Here are the key milestones we'll be delivering:
-
Web framework integrations: Official adapters for Next.js, Elysia, Fastify, and Koa, making it seamless to add federation to existing applications
-
ActivityPub debug & development tools: Real-time debug dashboard with WebSocket monitoring, federation lifecycle hooks, and implementation checklist CLI to make federation interactions transparent and debuggable
-
Storage & infrastructure enhancements:
SQLiteKvStorefor robust file-based storage across Node.js, Deno, and Bun, plus performance optimizations for production deployments -
Comprehensive documentation & examples: Specialized tutorials for building federated blogs, social networks, and content platforms, with complete working examples and migration guides
-
Observability & monitoring: Full OpenTelemetry metrics, performance benchmarking tools, and federation health dashboards for production environments
-
Advanced features & standards: FEP-ef61 (Portable Objects) support and implementation of emerging Fediverse Enhancement Proposals to keep Fedify at the cutting edge

Experimental support for multiple users landed with Ktistec release v2.4.15. "Experimental" means that it works for me, but hasn't seen enough testing for me to call it "ready for production". With that said, it's unlikely you'll lose your data.
There are lots of intentional design decisions that fit my vision for Ktistec but may surprise you. Here they are:
Every user is an administrator. That doesn't mean users have access to each other's posts and data, but it does mean all users have access to the shared parts of the site—they can change the site description, for example—and they can add new users. So only add people you trust.
If you want to add another user, create an account for them and give them their username and password. There is no self-registration. There are no invitations.
Beyond adding a user, there is no support for user management. You can't even boot a user from your site. Users can delete themselves, however.
There is no support for content moderation. Only add people you trust.
TL;DR Multi-user support in Ktistec is suitable for small teams, families (biological or chosen), and your personal avatars. There are better tools for online communities.
Here's the full set of changes:
Added
- Add support for multiple user accounts.
Fixed
- Hide attachments behind the summary. (fixes #125)
- Mark actors as up after refreshing their profile.

［ap_excerpt］で改行が削除されちゃう
#ActivityPub #Fediverse #Mastodon #WordPress #プラグイン #マストドン #仕様
気兼ねなく長文を書けるように、設定の「投稿コンテンツ」を、投稿の全文が表示される［ap_content］ではなく、抜粋が表示される［ap_excerpt］を使うようにしたのだけど、マストドンで見ると段落内の改行が削除されてしまっていることが気になってる。最近の投稿だと、段落内で改行して次の行にURLを書いたのだけど、前の行の尻にぴたりと付いてしまう。段落を変えれば良いのだけど…。
https://ishii00141.stars.ne.jp/20250731-0821-3185/
通常の文章であれば、私の場合は改行後の文章の前に全角スペースを入れるので、一応区切りは分かる。
でも、やっぱり、マストドンで見てもちゃんと改行されていたら嬉しい。何か方法はないだろうか？

No matter your views on Bluesky/ATProto or ActivityPub/the Fediverse, one thing is apparently agreed upon between fedi and Bluesky users: the fact that Legoshi is cute.
