/*
Purpose: Validate API contract helpers and message normalization logic.
Key Exports: None (package tests).
Role: Keep shared contract behavior deterministic without cgo dependencies.
Invariants: Decoded message times are normalized to UTC.
Invariants: Message tags are sourced from Message.Meta.Tags.
Notes: These tests run under `CGO_ENABLED=0` in bindings-go-contract-test.
