• Changed subagent and refinement guidance to favor non-blocking subagent tasks by default, use disk-backed tracking for long-running fan-out, inspect or message live subagents when agent observation/messaging skills are available, and capture reusable delegation roles, procedures, facts, preferences, and prompt addendums with /refine.
• Changed attach_image to resize and compress large inline image attachments before storing them for rendering and replay (#340 by @sethkarten).
• Fixed heartbeat and goal continuation prompts rendering like ordinary user messages (ENG-4482).
• Fixed /heartbeat guidance to show stop and the every <duration> <instruction> interval syntax (ENG-4484).
• Fixed login dialogs in fullscreen so sign-in URLs can be selected natively (ENG-4480).
• Fixed provider auth failures leaving stale credentials shown as connected in /login (ENG-4491).
• Fixed typing into the prompt after highlighting an inline subagent (ENG-4494).
• Fixed session-targeted heartbeat jobs staying scheduled after sessions are killed or saved sessions are deleted (#332).
• Fixed self-updates interrupting and automatically resuming daemon sessions instead of waiting for long-running work to finish.
• Fixed provider errors being surfaced instead of retried within the retry budget (ENG-4503).
