mux

This release focuses on durable workflows, agent memory, and background automation.

Durable workflows

• First-class nested workflows, inline workflow_run source, and streamlined authoring
• Workflows right-sidebar tab with live run streaming
• Wall-clock workflow scheduler, workspace tags, and workspace.* host actions
• /orchestrate routes to durable workflows with a gate/fixup verification loop
• Workflow CLI improvements: worktree trust, mux trust command, and the wf alias

Agent memory (experiment)

• Memory tool with global, project, and workspace scopes
• Curation UI, hot-set preloading, and background dream consolidation

Background automation

• Background bash monitors that wake the agent on matching output
• Workspace heartbeats with trigger and when-busy scheduling modes
• Notifications for terminal background work, including monitors lost to a Mux restart

Models

• Claude Sonnet 5 and Claude Mythos 5 support
• Refusal fallback with a transcript badge (default: Fable 5 falls back to Opus 4.8)

UX

• Pin chats to the top of the sidebar and reorder them
• Continue an interrupted stream by clicking the interrupted splitter
• Workspace-staged ZIP attachments
• Optional sidebar age grouping

Plus roughly 75 fixes and several performance improvements, including sealed chat history rotation at compaction boundaries.
