Enum SkillTrustLevel 

#[non_exhaustive]
pub enum SkillTrustLevel {
    Trusted,
    Verified,
    Quarantined,
    Blocked,
}

Trust tier controlling what a skill is allowed to do.

The ordering from most to least trusted is: Trusted → Verified → Quarantined → Blocked. Use SkillTrustLevel::severity to compare levels numerically, or SkillTrustLevel::min_trust to find the least-trusted of two levels.

Examples

use zeph_common::SkillTrustLevel;

let level = SkillTrustLevel::Quarantined;
assert!(level.is_active());
assert_eq!(level.severity(), 2);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Trusted

Built-in or user-audited skill: full tool access.

Verified

Signature or hash verified: default tool access.

Quarantined

Newly imported or hash-mismatch: restricted tool access.

Blocked

Explicitly disabled by user or auto-blocked by anomaly detector.

Implementations

impl SkillTrustLevel

pub const MISSING_ENTRY_FALLBACK: SkillTrustLevel = Self::Trusted

Trust level to assume when a skill has no entry in the trust map.

A missing entry means “never classified yet” (e.g. persistence not wired, or a transient trust-map read failure), not “known untrusted” — callers must not fall back to SkillTrustLevel::default (Quarantined) for this case, as that would misclassify legitimately trusted, already-vetted skills.

Examples

use zeph_common::SkillTrustLevel;

let trust_levels: std::collections::HashMap<String, SkillTrustLevel> =
    std::collections::HashMap::new();
let trust = trust_levels
    .get("some-skill")
    .copied()
    .unwrap_or(SkillTrustLevel::MISSING_ENTRY_FALLBACK);
assert_eq!(trust, SkillTrustLevel::Trusted);

pub const fn severity(self) -> u8

Ordered severity: lower value = more trusted.

Examples

use zeph_common::SkillTrustLevel;

assert!(SkillTrustLevel::Trusted.severity() < SkillTrustLevel::Blocked.severity());

pub const fn min_trust(self, other: SkillTrustLevel) -> SkillTrustLevel

Returns the least-trusted (highest severity) of two levels.

Examples

use zeph_common::SkillTrustLevel;

let result = SkillTrustLevel::Trusted.min_trust(SkillTrustLevel::Quarantined);
assert_eq!(result, SkillTrustLevel::Quarantined);

pub const fn from_severity(v: u8) -> SkillTrustLevel

Inverse of severity: reconstructs a level from its ordinal.

Any value >= 3 maps to Blocked — the most restrictive level — so a corrupted or out-of-range stored ordinal fails closed rather than open.

Examples

use zeph_common::SkillTrustLevel;

assert_eq!(SkillTrustLevel::from_severity(0), SkillTrustLevel::Trusted);
assert_eq!(SkillTrustLevel::from_severity(3), SkillTrustLevel::Blocked);
assert_eq!(SkillTrustLevel::from_severity(255), SkillTrustLevel::Blocked);

pub const fn as_str(self) -> &'static str

Returns the string representation used for database storage.

pub const fn is_active(self) -> bool

Returns true if the level is not Blocked.

Examples

use zeph_common::SkillTrustLevel;

assert!(SkillTrustLevel::Quarantined.is_active());
assert!(!SkillTrustLevel::Blocked.is_active());

pub const fn is_hidden_from_catalog(self) -> bool

Returns true for trust levels that must never appear on a listing surface with no trust-annotation mechanism — Blocked (explicitly disabled) and Quarantined (unreviewed / hash-mismatched) alike.

This is the hide strategy for surfaces that cannot show a trust level inline, e.g. the mention-picker catalog (SkillCatalogItem carries only name/description, no trust field). Contrast with the annotate strategy used by the XML skill-prompt catalog (zeph_skills::prompt::format_skills_catalog’s trust_levels parameter), which keeps a Quarantined/Blocked skill visible with a trust="..." attribute so the model/operator can still name it and promote it — that surface intentionally does not use this method. This method says nothing about matching-candidate selection or per-turn dispatch gating (TurnTrustFloor, weakest-link trust fold) either — those are separate concerns with their own filtering logic.

Examples

use zeph_common::SkillTrustLevel;

assert!(SkillTrustLevel::Blocked.is_hidden_from_catalog());
assert!(SkillTrustLevel::Quarantined.is_hidden_from_catalog());
assert!(!SkillTrustLevel::Trusted.is_hidden_from_catalog());
