specs/webvh/sync/update/v0_2/payload library

Classes

Payload: The same shape as webvh/_shared/0.1 SyncUpdate (the element of webvh/sync/batch/0.1), inlined because a top-level $ref payload does not survive every binding generator. The two MUST stay identical.
Response: WebVH Sync Update — response payload

ResponseStatus: applied — the replica now holds and serves exactly the submitted state. unchanged — it already held that state (or a newer version with identical content), and nothing was written.

payloadSchemaJson → const String: This specification's payload schema, as JSON text.
responsePayloadSchemaJson → const String: As payloadSchemaJson, for the success-response variant.
responseSpec → const SpecPolicy: The SPEC §7.2 policy for the success-response variant.
responseTypeUri → const String: The success-response form of typeUri (SPEC §4.4.1).
spec → const SpecPolicy: The SPEC §7.2 policy for the request variant, taken from this specification's front matter.
typeUri → const String: The Trust Task type URI this library's Payload is carried under.

Ext = Map<String, dynamic>: Vendor-namespaced extension object per SPEC.md §4.5.1. Each immediate key MUST be a reverse-DNS namespace; structure under each namespace is opaque to the framework.
