Kevin Veen-BirkenbachandClaude Opus 5.5 58187e8323 feat(orchestrator): inbox console, deny by channel and agent rule requests
The inbox shows the console output of a command under its "Ausführen"
row, kept to the same tail the job list shows. A deny picks its radio
channel (post by default, call, newsletter, broadcast, pan-pan,
security) and an optional reason; the passkey signs denial, channel and
reason, the hub verifies the proof before it stores or sends anything,
and the PermissionRequest hook quotes a reason only when it verifies.

Agents ask for an auto-approval rule through the MCP tool rule_request;
the request shows in the inbox with a dry run over the last seven days
and is accepted only with a passkey assertion the hub verifies against
the pinned keys and the hub origin, for every rule kind. Requests lapse
with the ask lifetime and are capped per agent and in total.

The image runs as nobody by default and carries the health check
command; compose keeps the timing.

🎯 Fix: 93 %
💥 Break: 4 %
💸 Cost: 98 %
⏱️ Time: 75 %
🛡️ Security: 100 %
🏆 Score: 100
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
