Vendor performance claims are not accepted as-is. Every failover/recovery figure in this stack is verified against production-sized state in chaos testing before it appears in customer-facing documentation.

Also maintained here: base images, OS versions, TLS libraries — kept in sync with the SBOM shipped per release.
