Ledger Migrations
SQL schema migrations for the governance ledger database
Overview
This directory contains SQL migration files that define and evolve the SQLite database schema for the agent governance system. Migrations are numbered sequentially and should be applied in order.
Migration Files
| File | Phase | Description |
|---|---|---|
001_multi_tenant.sql |
Phase 10 | Multi-tenant support tables |
002_marketplace.sql |
Phase 11 | Agent marketplace tables |
Migration 001: Multi-Tenant Support
Adds tables for multi-tenant architecture:
| Table | Purpose |
|---|---|
tenants |
Organization/customer records |
projects |
Workspaces within tenants |
tenant_quotas |
Resource limits per tenant |
tenant_usage |
Usage tracking for billing |
api_keys |
API authentication keys |
user_roles |
RBAC role assignments |
audit_log_tenant |
Tenant-scoped audit trail |
Migration 002: Marketplace
Adds tables for the agent template marketplace:
| Table | Purpose |
|---|---|
agent_templates |
Core template registry |
template_versions |
Version history with semver |
template_installations |
Installation tracking |
template_ratings |
User ratings and reviews |
template_downloads |
Download metrics |
templates_fts |
FTS5 full-text search index |
Applying Migrations
Migrations are applied automatically when the ledger API starts, or can be applied manually:
# Apply all migrations
sqlite3 /opt/agent-governance/ledger/governance.db < 001_multi_tenant.sql
sqlite3 /opt/agent-governance/ledger/governance.db < 002_marketplace.sql
# Verify tables
sqlite3 /opt/agent-governance/ledger/governance.db ".tables"
Schema Conventions
- Primary keys:
{entity}_id TEXT PRIMARY KEY - Timestamps:
TEXT DEFAULT CURRENT_TIMESTAMP(ISO 8601) - Foreign keys:
REFERENCES {table}({column}) ON DELETE CASCADE - JSON storage:
TEXTcolumns with JSON content - Boolean:
INTEGER(0/1) - Indices: Created for frequently queried columns
Adding New Migrations
- Create file:
00N_description.sql - Use
CREATE TABLE IF NOT EXISTSfor idempotency - Add indices for query performance
- Document in this README
- Test with fresh database
