Enum CapsSource 

pub enum CapsSource {
    AgentScopeSeal,
    Acdc,
}

The authoritative source of a grant’s capabilities + role for a policy decision.

There are two on-chain encodings of a capability/role grant, and they serve different decision grades:

• CapsSource::AgentScopeSeal — the Epic-E agentscope: Seal::Digest anchored in the delegator’s ixn. It is commit-time advisory: the offline fast path a verifier can read straight off the KEL without a live presentation. It is the low-latency convenience source, not an authority of record.
• CapsSource::Acdc — the F.4 capability credential. It is the authoritative caps/role source for credential-grade decisions, and authority derived from it is honored only through a holder-verified presentation (F.8) at the policy seam (context_from_credential).

Anti-divergence rule: the same grant MUST NOT be authored into both encodings with diverging caps/role. When both exist for one grant, CapsSource::governing selects the ACDC — the credential governs the credential-grade decision. The agentscope seal remains valid only as the advisory commit-time fast path. (Full ADR text is F.7.)

Variants

AgentScopeSeal

The Epic-E agentscope: delegator-anchored scope seal (commit-time advisory).

Acdc

The F.4 ACDC capability credential (authoritative for credential-grade decisions).

Implementations

impl CapsSource

pub fn governing( agentscope_present: bool, acdc_present: bool, ) -> Option<CapsSource>

Select the source that governs a credential-grade decision when both encodings exist for one grant: the ACDC always wins.

Args:

• agentscope_present: Whether an agentscope: seal exists for the grant.
• acdc_present: Whether an F.4 ACDC credential exists for the grant.

Usage:

assert_eq!(CapsSource::governing(true, true), CapsSource::Acdc);

Trait Implementations

impl Clone for CapsSource

fn clone(&self) -> CapsSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CapsSource

impl Debug for CapsSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for CapsSource

impl PartialEq for CapsSource

fn eq(&self, other: &CapsSource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
