Backend - DevRadar

I opened semantica-agi/semantica during a short coding break because the project’s graph-native approach addresses a problem I keep seeing in gateway deployments: context is available, but nobody can clearly explain where it came from, which account supplied it, or why it influenced a response.

Fair Queue for a Shared Free AI Server: 5-Dev Postmortem
