Kevin Veen-BirkenbachandClaude Opus 5.5 8ba45efd04 feat(hub): kvb-hub review hub with passkey-signed approvals
The kvb-hub is a local review hub in a container bound to 127.0.0.1: one page, JSON APIs and an MCP endpoint for the operator's inbox, asks, decisions, staged-commit reviews, the radio stream, the agent graph, the worktree tree, push-to-talk and read-aloud radio (Piper, whisper.cpp) and an optional LLM command line. The hub is only a relay. The host executors in hub/client (the runner user service, the PermissionRequest hook and the approval CLI the commit skills call) verify a WebAuthn passkey signature against keys pinned outside every sandbox, refuse replays and fail closed. scripts/hub.sh with make hub-install, hub-check, hub-pin, hub-runner and hub-hook installs and checks the hub; hub-hook writes ~/.claude/settings.json after a backup. make watch-check shows a stuck watch hook. The new kvb-git-diff skill and the commit skills route reviews through the hub; the test_hub_* suites replace test_hub.py.

Security review (kvb-think-criticize, three skeptics) fixed four holes: signed rules auto-approved chained shell commands; the client and LLM openers followed redirects, the LLM one with its bearer key; the worktree scan ran git fsmonitor and filter commands from agent-writable repos; compose set no memory, pids or health limits. Documented until core requirement 093, on the operator's word: the hub page is trusted while signing and pinning, local processes can forge the unsigned operator actions, and the container reads the host /tmp. Committed on the operator's word despite the gate: the passkey path is not yet verified live.
