 ## Detailed behavior and rationale
 
+### 0) Optional update (git installs)
+If this is a git checkout and doctor is running interactively, it offers to
+update (fetch/rebase/build) before running doctor.

 ### 1) Legacy config file migration
 If `~/.clawdis/clawdis.json` exists and `~/.clawdbot/clawdbot.json` does not,
 doctor migrates the file and normalizes old paths/image names. This prevents

+### 6) Hooks model validation
+If `hooks.gmail.model` is set, doctor validates the model reference against the
+catalog and allowlist and warns when it won’t resolve or is disallowed.

+### 7) Sandbox image repair
 When sandboxing is enabled, doctor checks Docker images and offers to build or
 switch to legacy names if the current image is missing.

+### 8) Gateway service migrations and cleanup hints
 Doctor detects legacy Clawdis gateway services (launchd/systemd/schtasks) and
 offers to remove them and install the Clawdbot service using the current gateway
 port. It can also scan for extra gateway-like services and print cleanup hints.
 Profile-named Clawdbot gateway services are considered first-class and are not
 flagged as "extra."

 Doctor emits warnings when a provider is open to DMs without an allowlist, or
 when a policy is configured in a dangerous way.

+### 10) systemd linger (Linux)
 If running as a systemd user service, doctor ensures lingering is enabled so the
 gateway stays alive after logout.

 creation in automation.

 Doctor inspects the daemon runtime (PID, last exit status) and warns when the

 on the gateway port (default `18789`) and reports likely causes (gateway already
 running, SSH tunnel).

 Doctor warns when the gateway service runs on Bun or a version-managed Node path
 (`nvm`, `fnm`, `volta`, `asdf`, etc.). WhatsApp + Telegram providers require Node,
 and version-manager paths can break after upgrades because the daemon does not
 load your shell init. Doctor offers to migrate to a system Node install when
 available (Homebrew/apt/choco).

 - The Gateway WebSocket binds to **loopback** on your configured port (defaults to 18789).
 - For remote use, you forward that loopback port over SSH (or use a tailnet/VPN and tunnel less).
 
+## Command flow (what runs where)
+
+One gateway daemon owns state + providers. Nodes are peripherals.
+
+Flow example (Telegram → node):
+- Telegram message arrives at the **Gateway**.
+- Gateway runs the **agent** and decides whether to call a node tool.
+- Gateway calls the **node** over the Bridge (`node.*` RPC).
+- Node returns the result; Gateway replies back out to Telegram.
+
+Notes:
+- **Nodes do not run the gateway daemon.** Only one gateway should run per host.
+- macOS app “node mode” is just a node client over the Bridge.
