The controller imports mesh-host/validate through a replace onto the forge that holds it, and every build — the build agent's go build in a fresh toolchain container, the Dockerfile's go mod download — would have fetched it through the public proxy and checksum database at build time: a merge breaking main on the network, the class Phase 1 removes. vendor/ is committed; go builds from it with nothing fetched, and refuses to build when it and go.mod disagree, so a pin moved without go mod vendor fails at once. The Dockerfile copies vendor/ and builds with GOPROXY=off.

NUID
A highly performant unique identifier generator.
Installation
Use the go command:
$ go get github.com/nats-io/nuid
Basic Usage
// Utilize the global locked instance
nuid := nuid.Next()
// Create an instance, these are not locked.
n := nuid.New()
nuid = n.Next()
// Generate a new crypto/rand seeded prefix.
// Generally not needed, happens automatically.
n.RandomizePrefix()
Performance
NUID needs to be very fast to generate and be truly unique, all while being entropy pool friendly. NUID uses 12 bytes of crypto generated data (entropy draining), and 10 bytes of pseudo-random sequential data that increments with a pseudo-random increment.
Total length of a NUID string is 22 bytes of base 62 ascii text, so 62^22 or 2707803647802660400290261537185326956544 possibilities.
NUID can generate identifiers as fast as 60ns, or ~16 million per second. There is an associated benchmark you can use to test performance on your own hardware.
