Struct Facet 

pub struct Facet {
    pub name: String,
    pub medium: String,
    pub scope: Vec<PatternEntry>,
    pub engagement: Option<Value>,
    pub preparation: Option<String>,
}

Legacy Facet (migrate-local) — the standalone engagement record of the retired three-file store. Parsed only by the migration legs; the live model carries this content inline as a Source’s facet half.

Fields

name: String

Stable name — projections reference a facet by this.

medium: String

The Medium (by name) this facet is a perspective on. A facet always references exactly one medium.

scope: Vec<PatternEntry>

Allow/deny selection over the referenced medium. A facet with no allow patterns is unscoped — a typed refusal at run time (no strategy diffs or enumerates the whole medium; the brief reports it as unmonitored), not “whole medium”. A facet that truly wants everything writes **/*.

engagement: Option<Value>

Engagement contract — verbs, tools, terminology, discipline. Free-form because the shape differs by medium type and by source/destination side; the engine does not interpret it.

preparation: Option<String>

Optional deterministic preparation step (string identifier, e.g. pdf-to-markdown). Unset for every text medium today. A facet that names a preparation the engine has no implementation for is accepted at rest but reported unsupported at run time — no silent skip, no crash.
