Six modules. One signed record per stem.
Nautives is an operational system, not a dashboard. Each module is built around a decision a compliance officer actually has to make.

Document ingestion
Email, SFTP and REST endpoints accept BDNs, COAs, MFM tickets and supplier emails. Each document is hashed, deduplicated and routed to its fleet workspace.
Extraction engine
OCR plus structured parsing for tabular and semi-structured fuel documents. Returns typed fields with per-field confidence scores.
Compliance validation
37 rules covering ISO 8217 quality limits, MARPOL Annex VI sulphur thresholds, charter party clauses and stemming reconciliation. Versioned and auditable.
Review workflows
Queue, assignment, comment, request-supplier and escalation paths. Keyboard shortcuts for the operators who live in this tool.
Reporting
Scheduled exports for class society, flag state and internal audit. Signed CSV, PDF and JSON with SHA-256 manifest.
Audit logs
Append-only log of every operator action, system event and rule decision. Filterable by actor, document and rule version.
