v0.32: Replication as a first-class kernel object.

Before v0.32, replication was encoded as Evidence.replicated: bool

• Evidence.replication_count: u32 — a scalar property on the finding. The kernel could not represent “lab A replicated this in human iPSC; lab B failed to replicate in mouse OPCs” — those are distinct epistemic facts, not a single count.

Each Replication is content-addressed (vrep_<16hex>) over its target finding, the actor that attempted it, the canonical conditions, and the outcome. This mirrors the vf_<id> pattern and makes replication chains queryable, citeable, and propagable through the link graph.

The legacy Evidence.replicated and Evidence.replication_count fields are preserved for backward compatibility; v0.32+ frontiers derive them from the structured collection on load.

Fields

id: String

vrep_<16hex>, content-addressed; see Replication::content_address.

target_finding: String

vf_<id> of the finding being replicated.

attempted_by: String

Stable actor id of the lab / curator / agent that attempted the replication. Same shape as FindingBundle.actor references.

outcome: String

One of replicated, failed, partial, inconclusive. Stored as a string for forward-compat with future outcome taxonomies; validated against VALID_REPLICATION_OUTCOMES.

evidence: Evidence

Evidence collected from the replication attempt. Reuses the existing Evidence shape so confidence math stays consistent.

conditions: Conditions

Conditions under which the replication was attempted (model system, species, in_vivo/vitro, etc.). The conditions field is what makes “replicated in mouse but failed in human” a representable fact.

provenance: Provenance

Provenance of the replicating paper / preprint / lab notebook.

notes: String

Free-text reviewer note. Often the most important field for partial / inconclusive outcomes.

created: String

Original creation timestamp (RFC 3339).

previous_attempt: Option<String>

If this attempt extends or refines a previous one, the vrep_<id> of that earlier attempt. Allows replication chains (lab A → lab B refines → lab C generalizes).

Implementations

impl Replication

pub fn content_address( target_finding: &str, attempted_by: &str, conditions: &Conditions, outcome: &str, ) -> String

Compute the content-addressed ID per v0.32 spec: SHA-256(target_finding | attempted_by | normalize(conditions.text) | outcome). Returns first 16 hex chars prefixed with “vrep_”.

conditions.text is normalized by the same lower/whitespace/punct rules as FindingBundle::normalize_text so two replications with trivially-different condition prose produce the same id only when the substantive conditions match.

pub fn new( target_finding: impl Into<String>, attempted_by: impl Into<String>, outcome: impl Into<String>, evidence: Evidence, conditions: Conditions, provenance: Provenance, notes: impl Into<String>, ) -> Self

Construct a new Replication with a freshly-derived id and created timestamp set to now.

Trait Implementations

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

Performs copy-assignment from source.

impl Serialize for Replication

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
