Phase 1B: privateclaw verify now validates both layers of TEE attestation: 1. Orchestrator attestation (Attestation-Report from tee-proxy) — existing check 2. Lunal upstream attestation (X-Upstream-Attestation-Report from tee-proxy v0.3.0+) — new: decodes base64+gzip, runs attestation-cli verify, reports "Upstream (Lunal) VCEK Chain: VALID" on success Both layers must pass for step [4/5] to succeed. If the upstream header is absent (tee-proxy pre-v0.3.0 or Lunal not sending), a WARN is shown instead of a hard fail for backward compatibility.
