+At launch, `cli.py` reads `CLAUDE_BOTTLE_OAUTH_TOKEN` from the host
+env and forwards it into the cred-proxy container's environ — never
+into the agent's. The agent receives `ANTHROPIC_BASE_URL` pointing at
+`http://cred-proxy:9099/anthropic` and a non-secret placeholder for
+`CLAUDE_CODE_OAUTH_TOKEN` (claude-code refuses to start without one;
+the proxy strips and replaces the header on every request). `printenv`
+inside the agent does not surface the real token, and the value is
+never written to disk or placed on argv on the host.
+
+A bottle without an `anthropic-base-url` route has no path to the
+Anthropic API — there is no fallback that forwards the token directly
+to the agent. Caveats: the token is bound to your subscription tier
+(Pro/Max/Team/Enterprise), it does not work with `claude --bare`
+(which only reads `ANTHROPIC_API_KEY`), and if it leaks, regenerate
