+### Critical Variables for Startup Scripts
+
+**IMPORTANT**: Startup scripts must explicitly `export` these variables for Python subprocess inheritance.
+
+#### Production (3002)
+Required exports in `run-server-3002.sh` and `run-worker-3002.sh`:
+```bash
+export MOMENTRY_OUTPUT_DIR=/Users/accusys/momentry/output
+export DATABASE_SCHEMA=public
+export MOMENTRY_REDIS_PREFIX=momentry:
+export MOMENTRY_SERVER_PORT=3002
+```
+
+#### Playground (3003)
+Required exports in `run-server-3003.sh`:
+```bash
+export DATABASE_SCHEMA=dev
+export MOMENTRY_SERVER_PORT=3003
+export MOMENTRY_REDIS_PREFIX=momentry_dev:
+export MOMENTRY_OUTPUT_DIR=/Users/accusys/momentry/output_dev
+```
+
+#### Why This Matters
+- Rust process loads `.env` via `dotenv`
+- Python subprocess inherits environment from Rust process
+- Without explicit `export`, dotenv variables are only available inside Rust
+- Python scripts like `store_traced_faces.py` will use hardcoded defaults if not exported
+
+#### Config Directory
+Environment-specific configuration files:
+- `config/production.env` - Production-specific variables
+- `config/development.env` - Development-specific variables
+- `config/test.env` - Test environment (if needed)
+
 ### Processor Timeouts
 - `MOMENTRY_ASR_TIMEOUT` - ASR timeout in seconds (default: 3600)
 - `MOMENTRY_CUT_TIMEOUT` - CUT timeout in seconds (default: 3600)

+5. **驗證環境變數配置**
+   - ✅ Startup scripts export all required environment variables
+   - ✅ Python scripts don't use hardcoded paths
+   - ✅ Environment variables consistent across:
+     - `.env` / `.env.development`
+     - Startup script `export`
+     - Python script `os.environ.get()`
+   - ✅ Config directory has environment-specific files
+   - ✅ AGENTS.md documents all required exports
+
 ### 重要性
 - 避免 release binary 與 current source code 不一致
 - 方便追蹤特定 release 的程式碼狀態
