Audience: platform engineers shipping OpenClaw on hosted Apple Silicon who want a CI gate that fails before bad JSON reaches launchd. This note assumes 2026.3.x behavior, Node 22.12 or newer, and a disposable workspace on a remote Mac runner. You will get a prerequisites list, ordered commands, error signatures for invalid-key, artifact guidance, and links to gateway hardening, skills rollback doctor, and model auth troubleshooting. Simplified Chinese companion: zh version. All listed pages stay readable without logging in.

Pain points this gate is meant to catch

  1. Silent drift: developers paste provider blocks into openclaw.json while the daemon still reads an older plist path, so production accepts traffic with empty secrets.
  2. Opaque errors: validation prints invalid-key without a human-readable pointer, and on-call wastes hours diffing entire trees instead of one JSON path.
  3. No rollback story: merges land Friday night without a tarball of the last known-good gateway bundle, so restore becomes guesswork across APFS snapshots.

Decision matrix: where validation should run

Stage Strength Risk
Pull-request job on remote Mac Matches darwin_arm64 paths, file modes, and case sensitivity of production Queues compete for CPU; keep jobs short with shallow clones
Pre-merge protected branch Blocks bad JSON before artifacts promote Requires redacted fixtures so secrets never hit logs
Post-deploy smoke Catches hot-reload gaps listener tokens still resident False greens if probes hit a canary port only

Prerequisites checklist

Work through the list slowly. Skipping a row is how invalid-key returns in production while CI stayed green.

  • Node v22.12.0 or newer on the runner; print semver in the job log for auditors.
  • Global CLI pinned to OpenClaw 2026.3.x with the same npm prefix the daemon user will use.
  • Repository copy of openclaw.json referenced by OPENCLAW_CONFIG_HOME or your chosen env contract.
  • Fixture secrets injected as masked variables never committed even when validation only checks shape.
  • Disk headroom on APFS for temporary tarballs and validate caches above twenty gibibytes free per shared host.
  • Outbound allowlist already mirrors gateway prefetch expectations if validate spawns provider probes.

Step-by-step commands

Execute in order. Adjust paths to your org but keep the separation between ephemeral workspace and daemon home explicit in logs.

node -v
node -e 'const p=process.versions.node.split(".").map(Number);process.exit(p[0]>22||p[0]===22&&p[1]>=12?0:1)' && echo "node 22.12+ ok"

npm install -g "openclaw@^2026.3.0"
which openclaw

export OPENCLAW_CONFIG_HOME="${CI_PROJECT_DIR:-$PWD}/.openclaw-ci"
mkdir -p "$OPENCLAW_CONFIG_HOME"
cp ./config/openclaw.json "$OPENCLAW_CONFIG_HOME/openclaw.json"

CKPT="openclaw-checkpoint-${CI_COMMIT_SHA:-$(date +%s)}.tgz"
tar czf "$CKPT" -C "$OPENCLAW_CONFIG_HOME" openclaw.json 2>/dev/null || true

openclaw doctor
openclaw config validate --config "$OPENCLAW_CONFIG_HOME/openclaw.json"

When validation fails, capture the dotted path next to invalid-key. Open only that subtree, fix the provider or auth reference, and rerun. After changing listen interfaces, TLS material, or plist EnvironmentVariables, assume hot reload is incomplete on 2026.3.x: restart the daemon, rerun openclaw doctor, then revalidate before merging.

# Example: surface invalid-key lines for CI logs (stderr kept)
openclaw config validate --config "$OPENCLAW_CONFIG_HOME/openclaw.json" 2>&1 | tee validate.log
grep -n "invalid-key" validate.log || true

Common error signatures and troubleshooting

Signature Meaning First response
invalid-key with dotted path Schema rejected a property usually because the secret env var is empty or the provider slug moved between minor releases. Open the path print env | sort for the job user diff against launchd export restart if production mismatch.
Exit 3 after validate while doctor is clean Often a second config file shadowing the first or a relative import resolved differently on APFS. Print realpath for both files unify on absolute paths in plist.
Hot reload claimed success yet old port listens Listener lifecycle bug class across minor versions treat as cold restart path. Stop job unload plist start sleep two seconds lsof -nP -iTCP verify PID turnover.

CI artifact archive integration

Upload validate.log, a redacted copy of openclaw.json with secrets replaced by placeholders, the tarball manifest sha256sum "$CKPT", and a JSON summary your observability stack already ingests. Retain artifacts at least fourteen days so weekend incidents have context. Pair uploads with the same bounded webhook retries described in Argo CD webhook summaries so failures do not spam on-call.

Pre-merge checklist (copy into PR template)

  • Node printout shows 22.12+ and OpenClaw shows 2026.3.x.
  • openclaw doctor and openclaw config validate both exit zero on the Mac runner.
  • Rollback tarball checksum recorded in the PR body or ticket.
  • Daemon restart performed if any listener TLS or env block changed.
  • Artifacts uploaded and retention policy noted for compliance.

FAQ

Should validate call live providers? Prefer dry validation plus a separate canary job so flaky egress does not block every PR.

Where do I store checkpoints? Use object storage or an internal artifact registry; never rely on the runner alone after the job ends.

Summary

A cheap CI gate on a remote Mac pays for itself the first time invalid-key points to a single JSON line instead of a midnight rebuild. Pair validation with checkpoint tarballs, explicit Node 22.12+ logging, conservative assumptions about gateway hot reload on 2026.3.x, and durable artifacts.
