HTTP, Bolt, and gRPC transports feature-complete. Zero dependency-security
advisories (grpc 1.0.4 + mint adapter). The entire 139-test integration
surface live-proven on ArcadeDB 26.9.1-SNAPSHOT, fail-closed TLS on both
gRPC and Bolt mutation-proven. CI green on the release commit (unit matrix
1.15/1.20 + full live-integration job incl. mix audit; actions SHA-pinned).
Package verified with mix hex.build. Cross-vendor reviewed.
