Cooling Checklist (30 Days)
For the next 30 days, treat these as frozen invariants: do not change EventEnvelope format/schema semantics, do not reorder top-level envelope fields, do not change timestamp precision (UTC Z, seconds-only), do not change payload key-sorting rules (objects sorted recursively; arrays preserve order), do not change the JSONL newline byte contract (one LF per line), and do not silently change hash algorithms when/if leaf hashing is introduced—only evolve via an explicit schema/version bump.
