Checksum Verification

Validation Method

SQLx uses SHA-256 checksums stored in _sqlx_migrations.checksum column (bytea format).

Checksum Status

✅ All checksums valid - No integrity issues detected

Sample Checksums:

Migration 1:  57d189d8e2563f3baff62c6e4c1b6058f3142666db31aad46c832f73b7601fd4...
Migration 20: adccd9500ffe41d112e90629853f82141b68bb90b8f2f897c581bc8f1c9f57aa...
Migration 20250826000001: 14d97ab9b6accf9bb434816b4b0f912b52a9474d5e0fe6ba6a2ea4f3a5d5302b...

Verification: All 21 migrations have checksums stored and validated by SQLx.

Duration: All migrations completed within ~44 minutes
Order: Sequential (1 → 2 → 3 → ... → 20 → 20250826000001)

Sequence Validation

✅ Chronological order maintained

• Migrations 1-20: Standard numeric sequence
• Migration 20250826000001: Special timestamp-based migration (fix for partitioned constraints)

No Gaps or Conflicts

• No missing versions

Critical Schema Components

Migration 001: Trading Events (29.7KB)

Purpose: Core trading event schema with nanosecond precision Execution Time: 196.57 seconds

Key Features:

• Custom ns_timestamp domain (nanoseconds since Unix epoch)
• Trading event types enum (19 event types)
• Order side and status enums
• Extensions: uuid-ossp, btree_gin, pg_stat_statements, timescaledb

Migration 020: Executions Table (3.4KB)

Purpose: Order execution tracking for load testing (Wave 127, Agent 118)
Execution Time: 12.06 seconds

Schema Validated:

CREATE TABLE executions (
    id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
    order_id UUID NOT NULL,
    account_id VARCHAR(64) NOT NULL,
    symbol VARCHAR(32) NOT NULL,
    side order_side NOT NULL,
    quantity BIGINT NOT NULL CHECK (quantity > 0),
    price BIGINT NOT NULL CHECK (price > 0),
    timestamp TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT CURRENT_TIMESTAMP,
    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT CURRENT_TIMESTAMP
);

Indexes Verified:

• ✓ executions_pkey (PRIMARY KEY on id)
• ✓ idx_executions_account_id (account_id, timestamp DESC)
• ✓ idx_executions_order_id (order_id)
• ✓ idx_executions_symbol_timestamp (symbol, timestamp DESC)
• ✓ idx_executions_timestamp (timestamp DESC)

Constraints Verified:

• ✓ CHECK: price > 0
• ✓ CHECK: quantity > 0
• ✓ FOREIGN KEY: order_id → orders(id) ON DELETE CASCADE

Migration 20250826000001: Partitioned Constraints Fix

Purpose: Fix constraints on partitioned tables
Execution Time: 1.87 seconds
Status: Applied successfully

Compliance & Audit

Audit System Status

✅ Audit logging operational

• Partitioned audit_log table with daily partitions
• Time-series optimization via TimescaleDB
• Retention: 23+ days of partitions visible

Compliance Features

SOX/MiFID II Requirements:

• ✓ Immutable audit trail (audit_log)
• ✓ Transaction tracking (transaction_audit_events)
• ✓ User authentication (users, sessions)
• ✓ MFA support (mfa_tables with pgcrypto)
• ✓ Compliance views (migration 004)

---

Risk Assessment

Migration Risks: ✅ LOW

No Issues Detected:

• ✓ All migrations applied successfully
• ✓ No failed migrations
• ✓ No pending migrations
• ✓ Checksums valid
• ✓ Foreign key constraints intact
• ✓ Indexes created successfully
• ✓ Extensions loaded properly

Rollback Capability

Each migration includes rollback instructions (commented in SQL files).

Example from 020_create_executions_table.sql:

-- To rollback this migration:
-- DROP TABLE IF EXISTS executions CASCADE;

Rollback Risk: LOW (all migrations include explicit rollback instructions)

---

Validation Tests

Test 1: Migration Count

SELECT COUNT(*) FROM _sqlx_migrations WHERE success = true;

Result: 21 ✅

Test 2: Failed Migrations

SELECT version, description FROM _sqlx_migrations WHERE success = false;

Result: 0 rows ✅

Test 3: Pending Migrations

cargo sqlx migrate info | grep -E "(pending|Pending)"

Result: No pending migrations ✅

Test 4: Core Tables Exist

SELECT tablename FROM pg_tables WHERE tablename IN 
  ('orders', 'positions', 'executions', 'users', 'sessions', 'risk_limits');

Result: 6/6 tables exist ✅

Test 5: Executions Table Schema

\d executions

Result: Schema matches migration 020 specification ✅

Discrepancy Analysis

Expected vs Actual

CLAUDE.md States: "17 migrations applied"
Actual Count: 21 migrations applied

Explanation: CLAUDE.md is outdated. Additional migrations added:

• Migration 018: enable_pgcrypto_mfa_encryption
• Migration 019: fix_compliance_integration
• Migration 020: create_executions_table (Wave 127, Agent 118)
• Migration 20250826000001: fix_partitioned_constraints

Action Required: ✅ Update CLAUDE.md to reflect 21 migrations

---

Recommendations

Immediate Actions (Critical)

1. ✅ Update CLAUDE.md migration count: Change "17 migrations" → "21 migrations"
2. ✅ Document backup files: Clarify purpose of .backup and .broken files
3. ✅ Remove deprecated migrations: Clean up migrations/.deprecated/ if no longer needed

Short-term Actions (1 week)

1. Database size monitoring:

   • Establish baseline size metrics
   • Set up growth alerts
   • Plan partition retention policy

2. Backup validation:

   • Test restore from backup
   • Verify checkpoint integrity

Long-term Actions (1 month)

1. Migration documentation:

   • Add detailed migration guide
   • Document rollback procedures
   • Create migration runbook

2. Schema versioning:

   • Tag current schema as v1.0
   • Establish versioning convention
   • Link migrations to releases

3. Performance tuning:

   • Analyze slow migrations (audit system: 22.5 min)
   • Optimize partition pruning
   • Review index usage
