Solution Architecture

Executive Summary

Solution Architecture defines the high-level architecture shape for Algosure v0.2. It describes solution layers and ownership alignment without defining implementation details, APIs, database schemas, or deployment topology.

Why This Exists

The Blueprint defines business and operating layers. Solution Architecture defines how those layers should be reflected in the future technical system at a high level.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Solution Architecture gives engineering, UX, AI, data, and integration teams a shared architecture picture before detailed design begins.

Layer Responsibilities

Layer	Responsibility
Mobile and Web Experience Layer	Presents Digital Procurement Headquarters experiences, approvals, tasks, reports, learning, marketplace, and executive workflows.
API and Contract Layer	Provides governed external and internal contracts without leaking domain internals.
Application / Modulith Layer	Coordinates use cases inside a modular monolith aligned to bounded contexts.
Domain Modules and Bounded Contexts	Own business facts, rules, lifecycle state, commands, and domain events.
Workflow and Process Layer	Executes Business Processes, SOPs, approval gates, tasks, retries, and exceptions.
AIOS and Intelligence Layer	Orchestrates Digital Professionals, context, reasoning, recommendations, approvals, and memory workflows.
Event Layer	Carries governed business events between modules, workflows, analytics, notifications, AIOS, and integrations.
Domain-Owned Data Layer	Persists source facts according to Domain ownership and audit requirements.
Integration Layer	Connects external systems and partners while preserving internal ownership.
Security, Tenant Isolation, and Audit	Enforces identity, authorization, tenant boundaries, approvals, and traceability.
Observability Layer	Provides operational visibility through logs, metrics, traces, audit, and health signals.

Architecture Alignment

Blueprint Layer	Solution Architecture Reflection
Domains	Domain modules and bounded contexts.
Practices	Workflow ownership, operational capability, SOP alignment, reporting and tasks.
Digital Professionals	AIOS and Intelligence orchestration with authority, memory, tools, and guardrails.
Business Capabilities	Application services and process entry points mapped to capability ownership.
Business Processes	Workflow and process execution layer.
AIOS	AI orchestration, context, reasoning, approvals, memory, and audit.
Executive Office	UX leadership experience, approval agenda, briefings, Board Room, action tracking.
