// Package random provides small cryptographically-random helpers shared across
// the control plane, CLIs, and the integration harness — a leaf package so a
// CLI or test binary can reuse them without importing heavier deps (e.g. the
// sqlite-backed store).

// Hex returns n cryptographically-random bytes encoded as hex (2n chars).
// crypto/rand.Read is documented never to fail (Go 1.24+), so its error is
// intentionally ignored.

	rand.Read(b) //nolint:errcheck // crypto/rand.Read never returns an error
	return hex.EncodeToString(b)
