- Add API_KEY environment variable with placeholder value 'change_me_to_a_strong_random_key'
- Include helpful comment explaining its purpose: authentication between Next.js and ML service
- Provide command for generating strong random value: openssl rand -hex 32
- Mark task 3.4 as completed
All 12 Next.js API routes that proxy requests to the ML service
(INFERENCE_API_URL / localhost:8001) now include the X-API-Key header
read from process.env.API_KEY. Affected routes:
- /api/predict
- /api/predict/batch
- /api/model/info
- /api/model/load
- /api/training/start
- /api/training/runs
- /api/training/runs/[run_id] (DELETE)
- /api/training/dataset-info
- /api/training/active
- /api/training/build-dataset
- /api/patterns/available
- /api/patterns/detect

- Import Header, Depends, Security from fastapi
- Add verify_api_key dependency: reads API_KEY env var, checks X-API-Key
header, raises HTTP 401 if key mismatch; fail-open if env var not set
- Apply Depends(verify_api_key) to all 14 non-health endpoints
- /health endpoint remains unauthenticated for liveness probes

- Create src/middleware.ts with Next.js middleware
- Reads API_KEY env var and checks X-API-Key header on all /api/* routes
- Skips auth for /api/health endpoint
- Fails open (with warning) when API_KEY is not configured
- Returns 401 Unauthorized when key is missing or mismatched

- Add `import re` to services/ml/app/main.py
- In POST /model/load: validate run_id matches ^[a-zA-Z0-9_-]+$ before DB lookup; use Path.resolve() + directory containment check before loading model artifact
- In DELETE /training/runs/{run_id}: validate run_id matches ^[a-zA-Z0-9_-]+$ before any processing; use Path.resolve() + directory containment check before deleting model artifact
- Both endpoints return HTTP 400 with {"detail": "Invalid run_id format"} on invalid input

Validate that run_id matches /^[a-zA-Z0-9_-]+$ regex before interpolating into the API URL.
Returns HTTP 400 with 'Invalid run_id format' error if validation fails.
This prevents potential URL injection attacks and invalid identifier usage.
Changes:
- Updated docker-compose.yml MLflow service port binding from 5000:5000 to 127.0.0.1:5000:5000
to restrict access to localhost only for security
- Marked task 1.7 as complete in tasks.md

- Changed PostgreSQL service port binding from 5432:5432 to 127.0.0.1:5432:5432 in docker-compose.yml
- This restricts PostgreSQL to listen only on localhost, improving security by preventing access from other interfaces
- Marked task 1.6 as completed

All DATABASE_URL values and postgres service env vars now use
\${POSTGRES_USER}, \${POSTGRES_PASSWORD}, \${POSTGRES_DB} interpolation
instead of hardcoded ml_user/ml_password/candle_annotator values.
Also updated pg_isready healthcheck to use the same env vars.
Closes task 1.5.
