Controlled lifecycle
Draft, review, approval, publication, and retirement are enforced by a role-based state machine.
Silo
Controlled records for regulated work.
Silo is a multi-tenant regulatory document and archive system with a controlled lifecycle from draft to retired, cryptographic audit chains, and a regulatory-intelligence layer for external sources.
Under inspection
The audit trail,
face up.
Documents, versions, and regulatory coverage from the running platform.
A controlled document library where every procedure and policy follows a governed lifecycle.
Version history and regulatory coverage stay attached to the controlled record.
Records under control
Documents that
answer for themselves.
Versioned, audited, tamper-evident — the properties an inspector checks are the ones built first.
Tamper-evident history
A checksum-chained audit log proves that document and workflow history was not silently altered.
Regulatory intelligence
External regulatory sources can be ingested, enriched, and queried alongside controlled records.
Real document work
Rich editing, PDF review, version comparison, and approval live in one governed workspace.
Under the hood
The stack.
The tools and languages Silo is built on.
