#!/usr/bin/env python3
"""tmux_auto_approver.py — Tmux worker management, worker tallies, and regex auto-approvals.

Supports:
1. Multi-socket and multi-agent discovery:
   - Shared host socket: /tmp/tmux-muse.sock
   - User sockets: /tmp/tmux-1000/default, /tmp/tmux-1000/lte
   - Agent netns sockets: /tmp/tmux-<node>.sock (muse, pip, 646, opm, dev, def)
2. Worker Tally:
   - Aggregates active sessions, windows, panes, current commands, PIDs, and runtimes.
3. Regex Auto-Approvals for on-board muse-code runs and autonomous agent workers:
   - Muse Code execution prompts ("Would you like to run the following... -> 1")
   - A/B/C choice prompts -> "A"
   - Numbered menus -> "1"
   - y/n confirmation prompts -> "y"
   - Press Enter prompts -> "Enter"
   - Safety guardrails (passwords, passkeys, destructive commands are never auto-approved)
4. State persistence & audit logging:
   - Desired state in .state/tmux-auto-approvals.json
   - Audit log stream in logs/tmux/auto-approvals.jsonl
5. Surface linking with https://box.muse-dev.online/
