+
+### Key Patterns
+
+**dbt Passthrough**: Custom `DbtGroup` class in `commands/dbt/__init__.py` intercepts unknown commands and passes them to the dbt CLI. This allows `brix dbt run` to execute `dbt run` while `brix dbt profile` is handled by brix.
+
+**Profile Models** (`modules/dbt/profile/models.py`): Pydantic models with discriminated unions for adapter types (DuckDB, Databricks). `DbtProfiles` provides YAML serialization via `from_yaml()`/`to_yaml()`.
 
-**CLI Entry Point** (`main.py`): Typer-based CLI with global callback pattern. Global options (--version, --log-level, --log-path, --log-json) are processed before subcommands. Add new commands via `@app.command()` decorators.
+**Template System** (`templates/`): Bundled files loaded via `importlib.resources`. Use `get_template(name)` to load content.
 
-**Logging System** (`utils/logging.py`): Terraform-style logging with environment variables (`BRIX_LOG`, `BRIX_LOG_PATH`, `BRIX_LOG_JSON`) and CLI flag overrides. Uses thread-safe singleton pattern. Call `get_logger()` from any module to access the logger.
+**Configuration**: Uses `pydantic-settings` with `BRIX_` prefix (e.g., `BRIX_DBT_PROFILE_PATH`). CLI arguments override environment variables.

-**Version Checking** (`version_check.py`): Non-blocking update checker using background threads. Caches results to `~/.cache/brix/` with 24-hour TTL.
