Follow-up cleanup from #115's review. isLoopbackBind was defined in server.mjs and copy-pasted into test-features.mjs (with a "keep in sync" comment, because importing server.mjs would run server.listen()). Extracted to a new importable lib/net.mjs; server.mjs and the test now import the one definition, removing the drift surface. Pure refactor — the function body is byte-identical to the prior server.mjs version, the TUI LAN-gate call site is unchanged, and the 8 isLoopbackBind truth-table tests now exercise the real shared function. 181 tests pass. ALIGNMENT.md: touches server.mjs but adds/removes no operation — it relocates an existing (#115) helper into a module. cli.js citation N/A under Rule 2. Independent fresh-context reviewer (opus): APPROVE (Iron Rule 10) — byte-identical body, exactly one definition, wiring + scope correct, no test dropped, scope clean. Closes #125.

/**
|
||
* openclaw-claude-proxy — OpenAI-compatible proxy for Claude CLI
|
||
*
|
||
* Translates OpenAI chat/completions requests into `claude --output-format stream-json` CLI calls,
|
||
* letting you use your Claude Pro/Max subscription as an OpenClaw model provider.
|
||
*
|
||
* Timeout design: single CLAUDE_TIMEOUT (default 600s / 10 min).
|
||
* No separate first-byte or idle timeout — Claude tool-use causes long pauses
|
||
* in the token stream (30s-5min) that make fine-grained timeouts unreliable.
|
||
* This matches LiteLLM, OpenAI SDK, and other major LLM proxies.
|
||
*
|
||
* Env vars:
|
||
* CLAUDE_PROXY_PORT — listen port (default: DEFAULT_PORT from lib/constants.mjs)
|
||
* CLAUDE_BIN — path to claude binary (default: auto-detect)
|
||
* CLAUDE_TIMEOUT — per-request timeout in ms (default: 600000)
|
||
* CLAUDE_ALLOWED_TOOLS — comma-separated tools to allow (default: expanded set)
|
||
* CLAUDE_SKIP_PERMISSIONS — "true" to bypass all permission checks (default: false)
|
||
* CLAUDE_SYSTEM_PROMPT — system prompt appended to all requests
|
||
* CLAUDE_MCP_CONFIG — path to MCP server config JSON file
|
||
* CLAUDE_SESSION_TTL — session TTL in ms (default: 3600000 = 1h)
|
||
* CLAUDE_MAX_CONCURRENT — max concurrent claude processes (default: 8)
|
||
* CLAUDE_BREAKER_THRESHOLD — failures in window before circuit opens (default: 6)
|
||
* CLAUDE_BREAKER_COOLDOWN — base ms to wait before retrying after circuit opens (default: 120000)
|
||
* CLAUDE_BREAKER_WINDOW — sliding window duration in ms (default: 300000 = 5min)
|
||
* CLAUDE_BREAKER_HALF_OPEN_MAX — max concurrent probes in half-open state (default: 2)
|
||
* PROXY_API_KEY — Bearer token for API auth (optional)
|
||
* CLAUDE_HEARTBEAT_INTERVAL — SSE heartbeat interval in ms on streaming path (default: 0 = disabled)

are usually transient (API load, large prompts) and the breaker's 120s+
