Node's built-in fetch ignores HTTP_PROXY, so every harness request connected directly regardless of what the user exported. Resolve one policy from the launch environment and install it as undici's global dispatcher, then wire the four surfaces a global dispatcher cannot reach: web_fetch's pinned transport, the OTLP exporter's node:http agent, the E2B SDK's own proxy option, and the environment a child process or worker thread is given. Each outbound call site carries an egress test that drives its real code path through a fake proxy; that measurement is what found the OTLP and E2B gaps.

llm/ — LLM capability family
English | 中文
Summary
The llm group provides the harness's model-call capability: one provider-neutral service through which any composition streams requests to a model provider, plus adapters, provider-specific request metadata, retry execution, and measurement. The core llm package defines the message, content-block, and stream-chunk vocabulary every plugin and the session log use; provider adapters translate a provider's wire format into that vocabulary; DeepSeek request-extension plugins contribute lifecycle-owned metadata outside model input; llm-retry re-runs failed requests at durable agent-step boundaries; and token-meter measures request and context pressure from the durable log. This page maps the group; each package README owns its per-package contract.
