Fix Exec Allowlist Miss

Diagnosing exec deny:

1. Check tools.exec.security and tools.profile in config
2. If profile=coding and security=full still denied → profile baseline missing exec
3. Use gateway tool: gateway('config.patch', {raw: '{tools:{profile:"full"}}'})
4. Hot-reload applies automatically in hybrid mode; explicit restart via gateway restart if needed
5. Verify: gateway('config.get', {}) → confirm profile=full

Config patch workflow (atomic, hash-verified):

1. gateway('config.get', {}) → capture payload.hash
2. gateway('config.patch', {raw: '...', baseHash: '\x3Chash>'})
3. Rate limit: 3 req/60s per deviceId+clientIp. Restart coalesces with 30s cooldown.

Hot-apply vs restart fields (hybrid mode): Hot-apply (no restart): channels, agent, models, routing, hooks, cron, session, messages, tools, browser, skills, mcp, audio, talk, ui, logging, identity, bindings Restart required: gateway.* (port, bind, auth, TLS, HTTP), discovery, plugins gateway.reload and gateway.remote changes do NOT trigger restart.

Minimax OAuth failure (ConnectionRefused / 401):

• Cron jobs use system-level auth, not current session OAuth → isolated session
• If minimax portal token expired: gateway('update.run', {continuationMessage: '...'}) attempts re-auth on restart
• Fallback: openclaw config set models.providers.minimax-portal.apiKey '\x3Ckey>'

Workflow

Config patch protected paths:

• Cannot patch channel-specific configs (e.g., whatsapp:8801322964987)
• Raw must be object, not string — wrong: gateway('config.patch', {raw: '{...}'})
  Right: gateway('config.patch', {raw: {channels: {...}}})
• Protected paths raise error: gateway config.patch cannot change protected config paths: \x3Cpath>
