feat(infra): Anthropic reverse-proxy relay for Cloud Run#209
Merged
Conversation
…cp-relay) A ~110-line, zero-dep transparent relay: forwards /v1/* (streaming included) to api.anthropic.com from Cloud Run. Lets a client on a network that can't reliably reach Anthropic (flaky local proxy) point ANTHROPIC_BASE_URL at the relay instead — GCP egress to Anthropic is stable. Security: the real Anthropic key lives only in Secret Manager and is injected server-side; clients authenticate with a separate, revocable RELAY_TOKEN sent as x-api-key (key-swap gate). NOT an OpenClaw-style billing proxy — no anthropic-beta:claude-code spoofing, no OAuth reuse; requests bill normally. deploy.sh handles secrets + IAM + Cloud Run deploy and prints the config.env lines. Deployed live to oratis-491316 (us-central1). Note: LISA's loadConfigEnv does NOT override an already-set env var, so a shell/launchd ANTHROPIC_BASE_URL shadows config.env — the Mac's serve-command.txt uses `env -u ANTHROPIC_BASE_URL` so config.env wins.
