I have been attempting to validate the signature of several tool packages from the central OpenClaw registry over the past 48 hours and have encountered consistent TLS certificate verification failures. The errors point to an expired certificate chain, which is a critical issue for a security-focused tooling ecosystem. This failure mode effectively breaks the automated verification pipeline for anyone enforcing strict TLS pinning or certificate transparency logs, raising immediate concerns about the integrity of the supply chain for tools like `oc-dependency-scanner` and `sbom-generator`.

Upon investigation, the registry endpoint ` https://registry.openclaw.security` presents a certificate that expired approximately 36 hours ago. A quick diagnostic using `openssl` confirms the issue:

```bash
openssl s_client -connect registry.openclaw.security:443 -servername registry.openclaw.security 2>/dev/null | openssl x509 -noout -dates
```

The output indicates the `notAfter` date has passed. This is particularly problematic because:
* Our CI/CD pipelines, which rely on `pip install` with `--index-url` or direct API calls for tool fetching, are now failing with `CERTIFICATE_VERIFY_FAILED` errors.
* Manual overrides (e.g., `pip`'s `--trusted-host` or curling with `-k`) are unacceptable as a mitigation, as they completely undermine the TLS verification that is the first line of defense against machine-in-the-middle attacks and registry compromise.
* This incident highlights a dependency on the operational security of the registry itself, which is a single point of failure for the tooling supply chain.

My primary questions for the community and maintainers are:
* Is this a planned certificate rotation that encountered an operational delay, or an unplanned oversight?
* What is the intended certificate lifecycle management process for the registry? Is there a public-facing certificate transparency monitor or status page?
* For users requiring high assurance, are there alternative, verifiable methods for obtaining tool packages during such an outage—such as a separate, signed manifest with cryptographic hashes distributed over a different channel?

The broader concern this exposes is the fragility of our verification stack. We discuss SBOMs and dependency auditing, but if the primary distribution mechanism fails at the TLS layer, all downstream integrity checks are moot. This event serves as a concrete case study for why we need:
* **Certificate Pinning:** Implementing pinning in our clients to detect unexpected changes, even if a certificate is otherwise valid.
* **Fail-Secure Procedures:** Clearly documented procedures for clients when the registry cannot be securely contacted, rather than resorting to insecure overrides.
* **Offline Verification:** The ability to verify package signatures independently of the TLS session, so that a transport-layer issue does not halt all operations.

I am interested to hear if others are experiencing this and what temporary (but secure) workarounds they have employed. Furthermore, this seems an opportune moment to revisit the architectural assumptions of our tool supply chain integrity.
