Struct FacetMismatch 

pub struct FacetMismatch {
    pub facet: &'static str,
    pub actual: &'static str,
    pub bound: String,
}

The single facet constraint a capability failed, named in the taxonomy’s own vocabulary.

Exists because the engine was write-only: admits answered yes/no and nothing reported WHICH axis said no, so both a user asking “why was this denied” and an author debugging a resolver had to bisect by editing facets and re-running. That is not a hypothetical cost — it is how an incomplete loopback delta got mistaken for a flawed approach.

Fields

facet: &'static str

Dotted facet path as the taxonomy spells it (network.payload, locus.remote).

actual: &'static str

The capability’s term (sends-host-data).

bound: String

The constraint it failed (<= fetches, one of [pinned, na]).
