Audience: operators who want a single reproducible gate on a remote Mac that chains machine-readable gateway status, openclaw doctor, and a port 18789 listener fingerprint before merge. This page lists headless flags, launchd-safe Node guidance, practical health bars, and an error matrix. Companion notes: config validate CI gate, non-interactive onboard merged logs, and gateway embeddings prefetch. Everything here stays readable without logging in.

Pain points this chain is designed to remove

  1. Human-only checks: engineers SSH in, skim pretty text, and miss regressions that JSON fields would have caught automatically.
  2. Port ghosts: a stale listener on 18789 from yesterday's experiment collides with today's job yet doctor still prints green because it never reconciled TCP state.
  3. PATH fiction: CI uses an nvm shim while launchd runs a different node, so the gate passes and production never restarts the right binary.

Decision matrix: what to trust first

Signal Strength Blind spot
Gateway status JSON Stable for CI diffing, pairs with artifacts and summaries. May lag right after crash; always bundle with lsof.
Doctor Catches provider wiring and disk permission classes early. Does not prove exclusive ownership of 18789.
lsof fingerprint Authoritative for listener collisions on the Mac. Needs parsing discipline so logs stay secret-safe.

Prerequisites checklist

Work the list top to bottom on the runner image you promote to production.

  • Node matches the daemon contract, logged with node -v and an absolute path, not an nvm alias.
  • OpenClaw CLI pinned globally; print command -v openclaw beside the plist ProgramArguments draft.
  • OPENCLAW_CONFIG_HOME exported to the repo copy under test; secrets arrive from masked variables only.
  • Prefetch job already warmed heavy dependencies so status reflects steady-state latency per your embeddings prefetch playbook.

Step-by-step gate script

Run after dependency install and before merge. Keep one log file for webhook summaries.

export CI=true
# Add any documented headless or JSON flags from `openclaw gateway status --help`
export OPENCLAW_GATE_LOG="${OPENCLAW_GATE_LOG:-openclaw-gate.log}"
: > "$OPENCLAW_GATE_LOG"

{
  echo "=== node path ==="
  command -v node
  node -v
  echo "=== openclaw path ==="
  command -v openclaw
  openclaw --version
  echo "=== gateway status json ==="
  openclaw gateway status --json > gateway-status.json
  python3 -m json.tool gateway-status.json | head -n 80
  echo "=== doctor ==="
  openclaw doctor
  echo "=== config validate ==="
  openclaw config validate --config "${OPENCLAW_CONFIG_HOME:?}/openclaw.json"
  echo "=== lsof 18789 ==="
  lsof -nP -iTCP:18789 -sTCP:LISTEN || true
} 2>&1 | tee "$OPENCLAW_GATE_LOG"

Promote the same absolute openclaw path into your launchd plist. After changing listen addresses or tokens, restart the daemon; partial hot reload is not a safe proof for listeners or auth material on busy gateways.

Copy-ready health bar (all must pass)

  • JSON: process state reports running, build stamp matches the CLI you pinned.
  • HTTP probe: loopback curl to the documented health route returns 2xx with the same token the edge will use.
  • TCP: lsof shows at most one expected PID or a deliberate alternate port for CI smoke.

Headless parameters and observability

Set CI=true and rely on flags from openclaw gateway status --help for JSON and non-interactive behavior. Avoid forcing pseudo-TTY in automation; instead tee merged streams to openclaw-gate.log and attach that file to your pipeline summary. When stable remote Mac capacity exists, schedule dependency pre-pull first so the gate measures real warm caches, then emit a short JSON summary object for Slack or email webhooks.

Common errors and first responses

Signature Likely cause First move
EADDRINUSE on 18789 Stale gateway or duplicate label. Stop the PID from lsof or move CI smoke to another port.
JSON healthy but curl fails Wrong bind interface or token mismatch. Compare openclaw.json listen stanza with curl host and Authorization header.
command not found: openclaw under launchd Minimal PATH without global npm bin. Use absolute ProgramArguments or export PATH in the plist.

FAQ

Should PR jobs install the daemon? Prefer CLI-only gates; reserve launchd for long-lived hosts so concurrency never fights over 18789.

Why prefetch before status? Cold caches create false alarms in latency and readiness probes; warm the node once per pool image as in validate gating plus prefetch docs.

How long to retain artifacts? At least fourteen days for incident review; store SHA256 beside each tarball.

Summary

Chaining status JSON, doctor, and an 18789 fingerprint on a remote Mac gives teams a cheap pre-merge signal that also feeds concise CI summaries after dependency pre-pull.
