# Sovereign Stack Services - Phoenix Cloud Services

This directory contains documentation for all Sovereign Stack services offered by Phoenix Cloud Services in the Sankofa marketplace.

## Overview

The Sovereign Stack is a comprehensive set of services designed to replace reliance on external platforms with owned core primitives, while retaining optional provider integrations via adapters. All services follow the principle that **no provider is System of Record (SoR)** - provider outages must not affect balances, identity, wallets, audit, or message delivery.

## Services

### Core Services

1. **[Phoenix Ledger Service](./ledger-service.md)** - Double-entry ledger with virtual accounts
2. **[Phoenix Identity Service](./identity-service.md)** - Identity, auth, and policy management
3. **[Phoenix Wallet Registry](./wallet-registry.md)** - Wallet mapping and signing policy

### Orchestration Services

4. **[Phoenix Transaction Orchestrator](./tx-orchestrator.md)** - On-chain/off-chain workflow orchestration
5. **[Phoenix Messaging Orchestrator](./messaging-orchestrator.md)** - Multi-provider messaging with failover
6. **[Phoenix Voice Orchestrator](./voice-orchestrator.md)** - TTS/STT with caching and routing

### Platform Services

7. **[Phoenix Event Bus](./event-bus.md)** - Durable events, replay, versioning
8. **[Phoenix Audit Service](./audit-service.md)** - Immutable audit logs and WORM archive
9. **[Phoenix Observability Stack](./observability.md)** - Distributed tracing, structured logs, SLOs

## Guiding Principles

1. **No provider is System of Record (SoR)**
   - Provider outages must not affect balances, identity, wallets, audit, or message delivery.

2. **Own the primitives; outsource the commodity**
   - Ledger, identity, wallet registry, orchestration, audit = internal.
   - Provider integrations are adapters behind stable internal contracts.

3. **API-first + event-driven**
   - Every domain emits events; all state transitions are auditable.

4. **Security by design**
   - Keys, PII, and money movement are the highest-risk domains; isolate, minimize, and monitor.

5. **Provider optionality**
   - Integrations are adapters behind stable internal contracts.

## Architecture

All services follow a consistent architecture pattern:

- **Internal Core**: Owned primitives that are always internal
- **Provider Adapters**: Optional integrations via adapters
- **Event Bus**: All state changes emit events
- **Audit Trail**: Immutable logging of all operations
- **Observability**: Distributed tracing and SLO monitoring
