# T01: Created full Docker Compose project (xpltd_chrysopedia) with PostgreSQL 16, Redis, FastAPI API, Celery worker, and React web services plus directory scaffolding

**Created full Docker Compose project (xpltd_chrysopedia) with PostgreSQL 16, Redis, FastAPI API, Celery worker, and React web services plus directory scaffolding**

## What Happened

Created the complete project directory structure with 8 top-level directories (backend, frontend, whisper, docker, prompts, config, tests/fixtures, alembic/versions). Wrote docker-compose.yml named xpltd_chrysopedia following XPLTD conventions from D001: bind mounts at /vmPool/r/services/chrysopedia_*, dedicated bridge network on 172.24.0.0/24, all ports bound to 127.0.0.1. Five services defined: chrysopedia-db (PostgreSQL 16-alpine), chrysopedia-redis (Redis 7-alpine), chrysopedia-api (FastAPI via Dockerfile.api), chrysopedia-worker (Celery via same Dockerfile), chrysopedia-web (React/nginx via Dockerfile.web). Created Dockerfiles for API and web, nginx.conf, backend/main.py with FastAPI health endpoints, .env.example with all spec environment variables, and config/canonical_tags.yaml with the 6 topic categories and 13 genres.

## Verification

docker compose config validates without errors (exit code 0) both with and without .env file present, confirming all service definitions, environment variable interpolation, volume mounts, network configuration, healthchecks, and dependency ordering are correct.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `POSTGRES_PASSWORD=test docker compose config > /dev/null 2>&1` | 0 | ✅ pass | 1000ms |
| 2 | `POSTGRES_PASSWORD=test docker compose config > /dev/null 2>&1 (without .env)` | 0 | ✅ pass | 1000ms |


## Deviations

Made env_file optional (required: false) to support fresh clones. Added docker/nginx.conf and frontend/package.json placeholders not in original plan but required for Dockerfile.web build context.

## Known Issues

None.
