Hub-and-Spoke Topology
Teacher spokes, campus hubs, and HQ consolidation preserve daily continuity while keeping authority, validation, reporting, and governance in the right tier.
Architecture
Local-first resilience with central institutional authority.
Indelo is designed for African operating reality: imperfect connectivity, distributed campuses, sensitive records, teacher-side work, and long-duration institutional responsibility.
Teacher Spoke Synchronization
Teacher laptops operate on a scoped working set tied to assignments — not a full school replica — while campus hubs remain the operational authority.
Explore synchronizationNamed Data Engines
Teacher spokes use encrypted local SQLite/SQLCipher working stores. Campus hubs and HQ run on Microsoft SQL Server — standard infrastructure DBAs already administer, back up, and trust.
Local-First Transaction Flow
User actions pass through business-rule validation, durable local storage, sync journaling, package verification, central validation, and SQL Server institutional authority.
File-First Sync Packages
Sync moves through portable media or customer-controlled networks. Connectivity is an optimization, not a dependency.
Country Configuration Layer
Academic structures, grade bands, terms, examination bodies, region labels, currency, and formats are treated as configurable data.
Pilot Narrow, Architect Wide
Indelo is built for Nigeria-first adoption and piloting with multi-campus school-group realities while preserving Anglophone African expansion readiness.
Version Discipline
Packages carry migration-level information. Machines must converge on compatible application and database versions before synchronization proceeds.
Repository Guard Parity
Sync applies through the same business-rule repositories as local entry. Imported data cannot bypass guards, ranges, locks, approvals, or institutional controls.
Synchronization discipline
Built to protect trust across distributed machines.
Packages are chained, signed, version-aware, and applied through the same business-rule validation as local entry — sync cannot bypass institutional controls.
Chained, verified synchronization packages detect and refuse silent modification, replay, gaps, out-of-order imports, and unsafe version drift. The goal is not merely to exchange data; it is to preserve confidence that campus history was not silently rewritten.
