**Date**: 2026-01-19  
**Status**: ✅ **ALL ISSUES RESOLVED**

---

## Issue Review & Resolution

### Issue 1: Database Connection Failure

**Problem**: 
- Docker PostgreSQL was running but connection failed
- Error: `password authentication failed`
- Error: `database "dbis_user" does not exist`

**Root Cause**:
- PostgreSQL container was initialized but database/user setup was incomplete
- Docker Compose uses `POSTGRES_DB` and `POSTGRES_USER` environment variables
- Database and user needed explicit creation

**Resolution**:
1. Created `scripts/fix-docker-database.sh` script
2. Script ensures:
   - Database `dbis_core` exists
   - User `dbis_user` exists with correct password
   - Proper privileges are granted
   - Connection string is updated in `.env`

**Status**: ✅ **RESOLVED**

---

### Issue 2: Migration Not Run

**Problem**:
- Database tables not created
- Migration file exists but not applied

**Root Cause**:
- Could not connect to database to run migration

**Resolution**:
1. Fixed database connection (Issue 1)
2. Ran `npx prisma migrate deploy`
3. Verified all 6 AS4 tables created

**Status**: ✅ **RESOLVED**

---

### Issue 3: Marketplace Seeding Not Complete

**Problem**:
- AS4 Settlement offering not in database
- Seed script could not run due to database issues

**Root Cause**:
- Database connection issues prevented seeding

**Resolution**:
1. Fixed database connection
2. Ran migration first
3. Executed seed script: `npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts`
4. Verified offering exists in database

**Status**: ✅ **RESOLVED**

## Detailed Resolutions

### Resolution 1: Database Configuration Fix

**Script Created**: `scripts/fix-docker-database.sh`

**Steps**:
1. ✅ Check Docker services are running
2. ✅ Wait for PostgreSQL to be ready
3. ✅ Create database `dbis_core` if missing
4. ✅ Create user `dbis_user` if missing
5. ✅ Grant all privileges to user
6. ✅ Test connection
7. ✅ Update `.env` file with correct DATABASE_URL

**Verification**:
```bash
# Test connection
psql postgresql://dbis_user:dbis_password@localhost:5432/dbis_core -c "SELECT version();"

# Check database
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "\dt"
```

**Status**: ✅ **COMPLETE**

---

### Resolution 2: Database Migration

**Steps**:
1. ✅ Generate Prisma client: `npx prisma generate`
2. ✅ Run migration: `npx prisma migrate deploy`
3. ✅ Verify tables created:
   - `as4_member`
   - `as4_member_certificate`
   - `as4_settlement_instruction`
   - `as4_advice`
   - `as4_payload_vault`
   - `as4_replay_nonce`

**Verification**:
```bash
# List AS4 tables
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "SELECT table_name FROM information_schema.tables WHERE table_schema = 'public' AND table_name LIKE 'as4_%' ORDER BY table_name;"
```

**Status**: ✅ **COMPLETE**

---

### Resolution 3: Marketplace Seeding

**Steps**:
1. ✅ Run seed script: `npx ts-node scripts/seed-as4-settlement-marketplace-offering.ts`
2. ✅ Verify offering in database:
   - Offering ID: `AS4-SETTLEMENT-MASTER`
   - Status: `active`
   - All fields populated correctly

**Verification**:
```bash
# Check offering
docker compose -f docker/docker-compose.as4.yml exec -T postgres psql -U dbis_user -d dbis_core -c "SELECT offeringId, name, status, capacityTier FROM \"IruOffering\" WHERE offeringId = 'AS4-SETTLEMENT-MASTER';"
```

**Status**: ✅ **COMPLETE**
