Summary

0.10.1 is about more Harnesses: alongside Claude Code and Codex, a Command can now run on Antigravity CLI (agy), Grok Build (grok), Muse Code (muse) or OpenCode (opencode). It also makes interruption stop Harness, Git and GitHub work across the board.

• Four new Harnesses (Spec: four more Harnesses (agy, Grok Build, Muse Code, OpenCode) #442), each selectable on the command line, in User config ([harness.<name>]) and in Setup: agy (Add the agy Harness (Antigravity CLI) #445), Muse Code (Add Muse Code Harness #444), Grok Build (Add the Grok Build Harness #446) and OpenCode (Add the OpenCode Harness #447). Claude and Codex were first gathered behind one Harness adapter with their behaviour preserved (Gather Claude and Codex into Harness adapters #441). Model and Effort are checked before any work starts. Sessions and Resumes run unattended and fully trusted under ADR 0013.
• Setup lists only installed Harnesses and validates their Model and Effort (Add the agy Harness (Antigravity CLI) #445, Add Muse Code Harness #444, Deepen Harness settings behind one Setup interaction #456).
• Failed Harness turns fail the Run even when the CLI exits zero. The PR stays a draft and no Resume starts (Deepen completed Harness session interpretation #458).
• Interrupting a Command stops each session's whole process tree on every Harness. This includes commands in their own process group or session, and commands started during the stop grace period (Stop every Harness session process tree on interruption #443).
  • Live sessions stay interruptible after the CLI exits (Unify Harness process lifetimes and preserve interruption #449).
  • Model/Effort checks can be interrupted before any Claim, worktree or Command log exists (Own all Model/Effort checks and make Setup interruptible #453).
  • Cancelling terminal Setup exits 1 with interrupted, restores the terminal and leaves User config and Credentials unchanged (Own all Model/Effort checks and make Setup interruptible #453).
• Ordinary Git and GitHub work stops on interruption, through the same Command execution owner as Harness sessions (Spec: Deepen Command execution for Git and GitHub #470, Share Command execution ownership for capture and streaming #469, Make Git execution interruptible with completion views #471, Make GitHub execution interruptible and preserve finishing workflows #472). Failed run salvage, confirmed Self-merge cleanup, Claim ending, worktree cleanup and Spec Ticket accounting still finish. An interrupted merge is accepted only when GitHub reports MERGED at the requested head.
• Ordinary Runs stop waiting for a repository lock when interrupted (Honor Command interruption during repository lock acquisition #474).
• Failed Harness sessions keep recoverable usage and warnings, and the original transport error is preserved (Retain Harness interpretation after transport failures #462, Unify Harness process lifetimes and preserve interruption #449).
• Malformed Harness stderr no longer hides a child Run's actual ending in Spec runs and Base fixes (Own child Run execution for Spec runs and Base fixes #464).
• Concurrent Ticket Runs are owned through teardown. On drop, every sibling's work is saved before Spec worktree cleanup, and duplicate starts are refused (Own concurrent child Runs through collective teardown #476).
• User config edits keep notification recipient examples in place at section and document boundaries, and render quoted headers idempotently (Prepare User config documents behind one validated interface #451).
• Claude and Grok stream interpretation now share one module, with their behaviour preserved (Deepen Claude and Grok Harness stream interpretation #460).

Also: docs and research updates (#426, #430).
