PRD 0018 chunk 4 spike: empirically verified that pipelock's SSRF guard checks proxied-request destinations (e.g. api.anthropic.com → public IP) and not source IPs of incoming connections. The bottle's own internal CIDR was being added to ssrf.ip_allowlist defensively, but that defense isn't load-bearing — direct pipelock probe (`curl --proxy http://pipelock https://api.anthropic.com/`) returns 404 from upstream rather than blocking on SSRF. So: - Networks become compose-managed (`internal: true` on the internal network; the egress one is a normal user-defined bridge). Compose creates + removes them via up/down. - launch.py drops the `docker network create` + `network_inspect_cidr` + pipelock yaml re-render dance. - The pre-create/external scaffolding from chunk 3 goes with it. End-to-end `./cli.py start` still works; cleanup leaves no orphans. If real-world use surfaces an SSRF block we hadn't predicted, the allowlist can come back via subnet-pinning rather than pre-create.
