Module artifacts 

Profile 0.2 artifacts, one file per protocol object:

• pca — PIC PCA COSE, the signed trusted authority checkpoint;
• continuity — PIC Continuity COSE, the signed continuity container;
• transition — PIC Continuity Transition COSE, the workload-signed causal authority transition;
• token — the PIC Token JWT external envelope.

Every signed-artifact hash in Profile 0.2 (root.pca_hash, predecessor.hash) is SHA-256 over the exact signed artifact bytes — never over a decoded payload or a re-serialized structure. The helpers here only accept raw byte slices, so the API shape enforces the rule.

Modules

continuity

PIC Continuity COSE (pic-continuity+cose): the signed continuity container carrying a trusted PCA checkpoint and either no proposed transitions (settled, null) or exactly one proposed transition (candidate).

pca

PIC PCA COSE (pic-pca+cose): the signed trusted authority checkpoint.

token

PIC Token JWT (pic+jwt): the external envelope.

transition

PIC Continuity Transition COSE (pic-continuity-transition+cose): the workload-signed causal authority transition.

Structs

AttenuationsWire

The optional attenuations member of a transition.

BitmapAttenuation

A section removal attenuation on the wire.

ContinuityRoot

The current trusted checkpoint carried by a Continuity: exact signed PIC PCA COSE bytes and their SHA-256.

ContractAdditions

Execution-contract additions on the wire: canonical [key, value] tuples, unindexed (the settlement verifier assigns indexes).

PcaChallenge

Challenge state carried by a PCA checkpoint: the challenge the next transition must answer.

PicContinuityPayload

PIC Continuity COSE payload.

PicPcaPayload

PIC PCA COSE payload: the signed trusted authority checkpoint.

PicTransitionPayload

PIC Continuity Transition COSE payload: the workload-signed causal authority transition.

Predecessor

The exactly-one predecessor reference. Current Profile 0.2 requires type = "pca" and hash = SHA-256(exact signed current root.pca bytes).

ProofOfRelationship

Typed Proof of Relationship container. type controls how evidence is parsed and validated; current Profile 0.2 requires "sd-jwt" with the exact UTF-8 bytes of the issuer-signed SD-JWT presentation.

TransitionChallenge

Challenge pair of a transition: it answers the predecessor’s challenge and emits the next one.

Functions

artifact_sha256

SHA-256 over exact signed artifact bytes.

Type Aliases

PicContinuityCose

COSE-signed Continuity.

PicPcaCose

COSE-signed PCA checkpoint.

PicTransitionCose

COSE-signed Transition.
