See where every branch is in review.list_agents and the sidebar show each reported branch's state: checks running, reviewer running, the verdict and its commit, or a failed merge and why.
Warnings about overlapping work across sessions. Assigning a task warns when another session in the same repo has unmerged work on the same files or the same issue number.
WSL sign-in opens your Windows browser. Sign-ins open it through wslview or explorer.exe, or print the URL clearly. Install hints now cover Linux.
Faster brindle start. Startup makes about a third as many synchronous calls.
Fixes
brindle -s works. It no longer reopens a running session on the old provider. -s before a subcommand and -s=codex both work, and an unknown name gives a clear error.
WSL uses Linux CLIs. Windows installs of codex and agy on the Windows PATH are skipped, and brindle doctor says when only a Windows install exists.
Every reported branch gets reviewed. Closing a finished worker no longer kills its pending check-and-review. A branch stuck in review with nothing running has its review restarted.
No duplicate reviewers. An agent that is still starting up is no longer taken for dead, so its review isn't started again and a completion audit's approval is recorded.
Merges into one branch run one at a time. A merge that fails a check is retried once before you're told, with the whole failure. Untracked scratch files no longer block review or merge.
Fewer false alarms. A worker busy on its task is no longer reported as stuck at a startup prompt. "Sign-in can't be verified" is sent once, not every minute.
No leaked gcloud processes. Every gcloud call is time-limited and leaves nothing running.
Sidebar. Mouse-wheel scrolling no longer lags. The sidebar uses the text logo everywhere, repaints after a session switch, and survives upgrades.
