- Move the council config to ~/.claude/agents-council/config.json, which the sandbox cannot write; the installer adds Edit(~/.claude/agents-council/**) to permissions.deny.
- Run every kvb hook as /usr/bin/python3 -I and rewrite old bare python3 entries.
- Refuse a council root that is a symlink, another uid's, or group or other writable, in watch, queue and radio.
- Run worktree_cleanup entries as argv without a shell in /, only for compose project names.
- queue block: tokenize every Bash command like bash (quotes, word-start comments, line continuations), and hold each held command to the Bash deny and ask rules of the managed, user and project settings; refuse a hold it cannot parse.
- radio: deliver fields on one line of at most 1000 characters, at most 10 rows.
Operator step after install: move ~/.config/agents-council/config.json to ~/.claude/agents-council/config.json.
MEDUSA acceptances (kvb-think-criticize 2026-11-06, skeptics A and B): ACP-SCAN-028 load_config (config outside the sandbox, Docker residual 093); CODEGEN-SCAN-004 and LLM06 run_cleanup and worktrees_command shell strings (operator config only); SAST-PATH-001 queue hold Popen (the caller's own command in its sandbox); PA-133 radio hook context (peer rows, clipped); JB-SCAN-641/616/2979 clip and MM-SCAN-058 replace (name matches).
