Programme-level operational metrics
A programme-scoped public reporting layer for aggregate Good Proof throughput, published in phases. No sensitive payloads. No portals. Just measurable metrics.
Operational transparency without data exposure
Audit/oversight-ready aggregate metrics
Programme-scoped proof of fail-closed enforcement
Programme
A scoped verification deployment governed by specific rules, lanes, and eligibility criteria.
Lane
A category of high-impact actions sharing common verification requirements within a programme.
Eligible Throughput
Production Stamps in opted-in lanes that meet privacy thresholds and programme rules.
Evidence Window
The bounded time period during which a Stamp's verification status remains authoritative.
Fail-Closed Event
Verification unreachable returns NOT VERIFIED; the system fails safely rather than defaulting to trust.
Validity Retention Rate
Percentage of Stamps remaining VALID throughout their evidence windows without status degradation.
Refresh Trigger
A material-change event forcing NEEDS_REFRESH status, requiring re-verification before reliance.
Withdrawal
A stop-rely event where WITHDRAWN status is propagated, invalidating prior verification.
Redacted format example and methodology documentation available now.
Monthly publishing begins once the programme meets [MIN_ELIGIBLE_THROUGHPUT_THRESHOLD] and privacy thresholds.
Sponsored lane reports with sampling audit and QA summaries.
Contract-grade boundaries for what enters the transparency layer.
Opt-in/Opt-out: Private programmes may opt out entirely. Individual lanes may opt in or out per programme configuration.
Auditor-ready metric definitions
Reporting period
Monthly calendar period (first day 00:00 UTC to last day 23:59 UTC).
Stamp deduplication
Each stamp_id counted once per reporting period; refreshes and status changes tracked separately.
Validity retention rate
Count of Stamps remaining VALID at window close ÷ total Stamps issued in period × 100.
Fail-closed events
Count of verification requests returning NOT_VERIFIED due to unreachable verification infrastructure.
Methodology versioning
Current version: v1.0. Changes published with revision notes; prior versions remain accessible.
Change log policy: Methodology changes are published with revision notes; prior versions remain accessible for audit continuity.
Operational transparency tied to Good Proof primitives.
Total Stamps issued within the reporting period across included lanes.
Percentage of Stamps remaining VALID through their evidence windows.
Verification unreachable → NOT VERIFIED. System failed safely.
Material-change events forcing NEEDS_REFRESH status.
Stop-rely events where WITHDRAWN status was propagated.
Human finality hours deployed for exceptions and dispute review.
Security and legal protections
Underwriter-ready safeguards
Fund verification capacity in specific impact categories
Sponsorship funds capacity: Guardian hours, sampling audits, and lane QA for categories sponsors care about.
Independence guarantee
If errors are found in a published report, a corrected report is published with revision history and date. Prior versions remain accessible for audit trail continuity.
Not a financial instrument. No promised returns. Metrics are operational transparency artefacts. Programme-scoped; eligibility rules apply.
