Canonical typed live-state checkpoint with additive Unicode prose.

Fields

schema_version: u32

Schema version of the checkpoint contract.

identity: ContextCheckpointIdentityV1

Parent, branch, and device identity.

lineage: ContextCheckpointLineageV2

Work-graph lineage references and authoritative artifact refs.

live_state: ContextCheckpointLiveStateV2

Portable Unicode live state.

carrier: Option<ContextCheckpointCarrierBindingV1>

Binding to a P6 carrier envelope, when the checkpoint travels in one.

engine_version: SemanticVersion

Engine version that produced the checkpoint.

created_at: UtcTimestamp

Canonical UTC creation timestamp.

updated_at: UtcTimestamp

Canonical UTC timestamp of the latest portable semantic update.

encryption_metadata: Option<ContextCheckpointEncryptionMetadataV1>

Metadata for an encrypted downstream projection, when present.

Implementations

impl ContextCheckpointV3

pub const SCHEMA_VERSION: u32 = 3

Schema version represented by this type.

pub const SCHEMA_ID: &'static str = CONTEXT_CHECKPOINT_V3_SCHEMA_ID

Schema identity represented by this type.

pub fn from_v2_unverified( checkpoint: ContextCheckpointV2, ) -> Result<Self, ValidationError>

Construct a V3 checkpoint from an already validated V2 value.

This is a structural migration only. It does not verify artifact ownership and therefore does not expose a signing payload; production callers must use the core lineage admission boundary first.

pub fn validate(&self) -> Result<(), ValidationError>

Validate every V3 invariant, including lineage and cross-field bindings.

pub fn canonical_bytes(&self) -> Result<Vec<u8>, ValidationError>

Return canonical compact JSON bytes with lexicographically sorted keys.

pub fn canonical_json(&self) -> Result<String, ValidationError>

Return the canonical JSON encoding as UTF-8 text.

pub fn from_canonical_bytes(bytes: &[u8]) -> Result<Self, ValidationError>

Decode exactly canonical V3 JSON and validate every invariant.

pub fn digest(&self) -> Result<Sha256Digest, ValidationError>

Domain-separated content identity of the complete V3 checkpoint.

Trait Implementations

impl Clone for ContextCheckpointV3

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContextCheckpointV3

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContextCheckpointV3

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
