Ask

Add chat branching from the current chat using the existing session.branch RPC. A branched child must appear as a normal flat chat with a lineage indicator rather than nested under its parent.

Files and APIs

  • Sources/HermternalCore/Net/GatewayClient.swift: the existing session.branch RPC, which takes the live session id and optional count and name.
  • Sources/Hermternal/AppModel.swift: branch action routing, child session state, and selection.
  • Sources/Hermternal/Views/SidebarView.swift: normal child row presentation and lineage indicator.
  • Sources/HermternalCore/Models/ChatModels.swift: branch parent/lineage metadata.

Acceptance

  • Branching invokes session.branch with the live session id and forwards optional count and name when supplied.
  • The returned child appears in the sidebar as a normal chat row, not as a nested row or hierarchical list child.
  • The child displays a clear lineage indicator linking it to its parent without changing the flat sidebar rule.
  • Selecting the branched child opens its transcript and keeps durable selection correct.
  • Branch failures leave the current chat and sidebar selection unchanged and report an actionable error.
