CanvasRegisterClockModel class
A signed merge clock for a single canvas object register.
The signature attests that the named actorDeviceKey authored a write of registerName at hlcTimestamp with a register value matching the digest embedded in the signed message. Verification is required on apply so that one device in a conversation cannot attribute writes to a sibling device.

Static Methods
-
create(
{required String canvasId, required String objectId, required CanvasRegisterName registerName, required String conversationKey, required String hlcTimestamp, String? registerJson, bool? isDeleted}) → Future< CanvasRegisterClockModel> - Signs a register clock with the current device's signing key.
-
digestFor(
{required CanvasRegisterName registerName, String? registerJson, bool? isDeleted}) → Future< String> - Computes the canonical value digest for a register write.
-
getMessage(
{required String canvasId, required String objectId, required CanvasRegisterName registerName, required String conversationKey, required String actorDeviceKey, required String hlcTimestamp, required String valueDigest}) → String - Builds the canonical signed message for a register clock.
