goldenassert

Overview ¶

Package goldenassert is the shared TEST helper for the golden-payload fixtures under internal/eventpayload/testdata — the cross-channel drift lock for the stable event `data` payloads.

Each fixture file is a full wire envelope {type,id,schema_version, created_at,data}. The canonical envelope-level lock lives in internal/eventpayload's own golden test; the per-builder tests (relay, agent, delivery, ws) call Data to assert that THEIR builder's marshaled `data` is byte-identical to the fixture's `data` subdocument. The TS and Python SDK payload tests parse the very same files, so a server-side field rename that would break an SDK type fails both sides against one artifact.
