NovaPath Assessment Coverage Audit

Choose this endpoint when you need to audit the structural integrity and completeness of an assessment-window dataset — specifically to disentangle whether observed learning gaps reflect true outcomes or simply missing data administrations. It is the right choice when you have aggregate histogram data (not individual records), want to validate whether delivered interventions are properly linked to baseline-followup pairs, and need to verify multiple integrity conditions (identity, retake rules, scale continuity, source independence) in a single call. Prefer it over general analytics endpoints when educational data quality, intervention causality validation, or compliance reporting is the primary concern.

• learnersByObservedWindowCount array length does not match expectedWindowCount + 1, causing schema validation error
• linkedBaselineFollowup exceeds deliveredInterventions, indicating inconsistent input
• Histogram values sum to a number incompatible with learnerCount, producing a coverage reconciliation warning
• Boolean verification flags set inconsistently (e.g., windowsVerified true but histogram gaps obvious), leading to a flagged audit report
• Missing required fields (e.g., no learnersByObservedWindowCount) returning a 400 bad request
• Payment of 0.2 USDC not completed via x402 protocol, resulting in 402 Payment Required response
