Struct Fingerprint 

pub struct Fingerprint {
    pub wire_version: u32,
    pub eventlog_schema: u32,
    pub crd_api_version: String,
    pub tool_catalog_hash: String,
}

The compatibility fingerprint of a build: the four axes that decide whether two builds interoperate and can read one another’s data.

Only equality matters — the numeric versions are compared for identity, not ordering, because any difference on a format axis is a coordinated move regardless of direction.

Fields

wire_version: u32

Protobuf/wire descriptor version the build speaks.

eventlog_schema: u32

Event-log schema version the build reads and writes.

crd_api_version: String

CRD apiVersion the controller reconciles (e.g. polychrome.dev/v1).

tool_catalog_hash: String

Hash over the tool catalog — the config-as-data surface (prompts, persona defs, model routing) that moves without a binary change.

Implementations

impl Fingerprint

pub fn new( wire_version: u32, eventlog_schema: u32, crd_api_version: impl Into<String>, tool_catalog_hash: impl Into<String>, ) -> Self

Build a fingerprint from its four axes.

pub fn runtime_target(&self) -> RuntimeTarget

The format-axis subset of this fingerprint — the runtime a config-as-data bundle must pin to ride on top of this build.

pub fn classify(&self, available: &Self) -> Compatibility

Classify available relative to this (the running) build.

The result names the least-disruptive move that applies the available release: Compatibility::Cold when a format axis moved, Compatibility::Hot when only the config-as-data surface moved, and Compatibility::Warm when the fingerprint is otherwise identical (a wire- and schema-compatible binary swap). This path never refuses — a full release brings its own binary, so a format change is a coordinated redeploy rather than an incompatibility. See StagedBundle::evaluate for the refuse-incompatible interlock on config-as-data bundles.
