Module compliance_score 

Phase 19.1 – compliance scoring on top of ComplianceReport.

Productizes the existing crate::operator_report::ComplianceReport into a user-facing 0..=1000 score with weighted factors:

Factor	Max points	Signal
Deny rate	300	denies / total_observed
Revocation rate	300	revoked_caps / observed_caps (or flag)
Velocity anomaly rate	150	anomaly_windows / total_windows
Policy coverage	150	lineage + checkpoint rates (averaged)
Attestation freshness	100	age of latest attestation vs. staleness

Weights sum to 1000. Each factor produces a 0..=max deduction; the final score is 1000 - total_deductions, clamped to [0, 1000].

This module is additive: it consumes a ComplianceReport without modifying its fields. Callers who already materialize a compliance report reuse its figures verbatim.

Structs

ComplianceFactor

Per-factor deduction detail (0..=max points).

ComplianceFactorBreakdown

Full factor breakdown for a compliance score.

ComplianceScore

Final compliance score for an agent over a window.

ComplianceScoreConfig

Options controlling scoring thresholds. Defaults match the roadmap’s 19.1 acceptance targets (zero denies in 1000 calls -> >900; any revoked cap -> <500).

ComplianceScoreInputs

Observed compliance inputs that are not carried by ComplianceReport.

Constants

COMPLIANCE_SCORE_MAX

Maximum possible compliance score.

DEFAULT_ATTESTATION_STALENESS_SECS

Default staleness threshold (seconds) beyond which the attestation freshness factor is fully deducted. Ninety days mirrors the default receipt-retention window in crate::receipt_store::RetentionConfig.

WEIGHT_ATTESTATION_FRESHNESS

Weight for the attestation-freshness factor.

WEIGHT_DENY_RATE

Weight (maximum-deducted points) for the deny-rate factor.

WEIGHT_POLICY_COVERAGE

Weight for the policy-coverage factor.

WEIGHT_REVOCATION

Weight for the revocation factor.

WEIGHT_VELOCITY_ANOMALY

Weight for the velocity-anomaly factor.

Functions

compliance_factor_breakdown

Build the per-factor breakdown without wrapping it in a score.

compliance_score

Compute the weighted compliance score for an agent.
