Struct GrantCoverage 

pub struct GrantCoverage<'a> {
    pub destination: &'a str,
    pub slot_schema_hash: &'a str,
    pub covered_capabilities: &'a [String],
}

The coverage record a grant binds: the pinned destination, the slot-schema hash, and the covered capabilities.

Borrowed so a caller can build it from decoded fields without copying. slot_schema_hash is #618’s template-coverage hash; covered_capabilities are stable kebab-case polyc_capability names (the consumer resolves them with CapabilitySet::from_names, which is fail-closed on unknown names). Changing the destination or the slot-schema hash changes the canonical, so a coverage drift voids the grant — a new approval ceremony is required.

Fields

destination: &'a str

The pinned egress destination the grant covers.

Canonicalization contract: the compact JSON of the template’s destination map serialized from a BTreeMap (key-sorted, no whitespace). Coverage equality is byte equality of this string, so the mint side (the enrollment ceremony) and every verify side (the dispatch resolver recomputing current coverage) MUST produce it the same way — always serde_json::to_string of the BTreeMap destination, never a hand-built string. A formatting-only difference reads as coverage drift and voids the grant.

slot_schema_hash: &'a str

The content-template slot-schema hash the grant covers (#618).

covered_capabilities: &'a [String]

The stable kebab-case capability names the grant covers.
