Architecture

FAOS is designed as a control-driven operations system for document-heavy B2B workflows. The architecture prioritizes company-level isolation, server-side enforcement, and traceable records.

Tenant Isolation Model

FAOS is multi-tenant. Each customer company operates within its own isolated workspace context. Requests are authorized against the authenticated session and mapped to a single company boundary.

• Company context is derived from authenticated sessions (not client-supplied parameters).
• Data access is enforced on the server side to prevent cross-company exposure.

Control Surfaces

FAOS focuses on operational controls that reduce downstream errors:

• Blocking rules when required information is missing or approvals are incomplete.
• Role-based access to sensitive modules and actions.
• Export activity logging for accountability and review.

Auditability

FAOS records key actions that affect operational integrity (for example: exports and configuration changes). “Audit” here refers to audit trail and traceability, not statutory audit.

Scope

This page describes high-level architectural boundaries and control principles. It does not describe statutory compliance automation, tax submission, or external audit services.
