- backends is now an ordered candidate list (first = preferred); channels report the backend actually serving via active_backend, surfaced in the doctor text report and --json - new agent_reach/probe.py really executes upstream commands and tells apart missing / broken (stale venv shebang after a system Python upgrade) / timeout, with a reinstall prescription for broken installs - all 13 channels migrated off which()-only checks: fixes bilibili false-positive "bili-cli 可用" on broken shims, misleading xiaohongshu "连接失败", rdt OSError crashing doctor, mcporter breakage masquerading as "未配置" - twitter: 15s probe + 1 retry (flaky 10s timeout), broken twitter-cli now falls back to bird instead of aborting the check - doctor survives per-channel exceptions; config supports per-channel backend override (<channel>_backend / <CHANNEL>_BACKEND env) - fix skill install/uninstall crash on symlinked skill dirs (the "[Errno None] None" warning from shutil.rmtree on a symlink) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
