Pure-Go, stdlib-only implementation of the LIC1 wire format: - ParseKey + Verify + ParseAndVerify for offline verification - HashFingerprint helper (SHA-256, matching the daemon's contract) - LoadPublicKeyPEM for the standard PKIX-encoded Ed25519 public keys the daemon emits - Client.Validate / Client.PublicKey for online checks against a running Keysat daemon - LicensePayload struct with idiomatic Go getters (IsTrial, IsFingerprintBound, IsExpiredAt, HasEntitlement) Wire-format crosscheck against the shared tests/crosscheck/vector.json (the same file the Rust, TypeScript, Python SDKs and the daemon itself test against). All four fixtures pass — v1 legacy fingerprint-bound, v2 trial with entitlements, v2 perpetual unbound, plus end-to-end PEM-load → ParseAndVerify signature roundtrip. Confirms byte-for-byte agreement across five independent implementations. No third-party dependencies. Module path: github.com/keysat-xyz/keysat-client-go go 1.21
