Build and deploy hydrabrainserver as the authenticated person-facing HydraBrain chat surface at https://hydrabrain.experiencenet.com. IAMNim owns login; the service owns only an opaque local browser session, server-side discovery, provider reachability filtering, and stateless browser chat. HydraCluster/HydraBrain credentials must never reach browser responses or logs. Package as a multi-architecture OCI HydraScale, launch on an ARM64 Pi HydraSkin node, publish through HydraScaleRouter, and verify live IAM redirect, provider discovery, streaming, cancellation, reboot/update behavior, and credential redaction.
Implemented and deployed HydraBrainServer.
Runbook and testbook are in the repository. An IAMNim-authenticated human chat is now the user acceptance step; there is no remaining infrastructure blocker.
