This broke credential lookup ('no default account profile set'). The proxy is for sandbox egress, not for host-side management ops. It's already configured inside the sandbox via buildAgentEnvironment() which sets HTTP_PROXY/HTTPS_PROXY and passes them to sbx exec --env. Security note: process.env (which may contain DOCKER_PAT) is safe to pass to sbx create because it's a host-side CLI command. The sandbox is a KVM microVM with hardware isolation — host env vars never reach the sandbox interior. Only sanitizeEnvForSbx()-filtered vars are passed to sbx exec.

Add a credential refresh step right before 'Execute GitHub Copilot CLI' to ensure sbx create can authenticate with Docker Hub. Auth step confirmed working: sbx create succeeds there. AWF step fails with 'secret not found' minutes later.

This breaks sbx credential lookup — sbx stores encrypted secrets at $XDG_CONFIG_HOME/sandboxes/ which defaults to ~/.config/sandboxes/. When XDG_CONFIG_HOME=/home/runner, sbx looks at /home/runner/sandboxes/ instead of /home/runner/.config/sandboxes/, causing 'secret not found'. Fix: unset XDG_CONFIG_HOME when it equals HOME before calling sbx create.

Port publishing on containers only attached to an internal network doesn't work — the host (and thus the sbx microVM) cannot reach them. Fix: when the agent runs in a microVM and network isolation is active, also attach api-proxy to the awf-ext bridge network (same as Squid). This makes published ports (10000-10004) reachable from the sbx gateway.

However, host.docker.internal resolves to the docker0 bridge (172.17.0.1) inside the sbx VM, which CAN route to containers on the awf-ext bridge network. Diagnostics proved: - 172.17.0.0:10000 → FAIL (timeout, no port publishing) - 172.17.0.1:10000 → OK (instant, docker0 bridge routes to awf-ext) - 172.17.0.0:3128 → OK (Squid has native port publishing) Use host.docker.internal for api-proxy URLs (COPILOT_API_URL, COPILOT_PROVIDER_BASE_URL, etc.) while keeping 172.17.0.0 for Squid proxy which has working port publishing. Also simplify health check to use host.docker.internal and remove the multi-IP diagnostic probing.
