Lake quality is governed at the contract, not at the query.
Audit-ready evidence as a property of the deployed system. Coverage and gap are continuous, not periodic; supervisory inspections receive structured lineage records aligned with control frameworks (ISO 27001, POJK, BSSN sectoral, UU PDP).
Investigative continuity across the retention horizon. Schema-governed lake retention, reproducible deterministic correlation, and chain-of-custody-aligned evidence preservation are preconditions of the investigation, not deliverables to assemble under deadline.
Lake quality decays without schema governance. Mega Lake Schema & Governance Studio is the contract layer — schema design, deployment, retention, and access control as first-class artefacts.
Schemas are versioned, deployed, and bound to access policy. Retention is policy-driven and auditable. Every read and write is governed by the schema contract.
Schema drift is detected at deploy, not at query.
Before: schema drift surfaced as broken queries.
Retention compliance is evidenced.
Before: retention was operationally enforced.
Every access is governed and logged.
Before: access was perimeter-controlled.
