| # Engineering Foundation | |
| ## Status | |
| Milestone 1 is implemented locally pending lockfile generation and verification. It contains no provider integration, database, live/paper account, external network request, or trading loop. | |
| ## Components | |
| | Module | Responsibility | | |
| | --- | --- | | |
| | `drift_quant.config` | Validates non-secret environment selection and log level. | | |
| | `drift_quant.secrets` | Loads required secrets at an integration boundary and redacts its string representations. | | |
| | `drift_quant.logging` | Emits structured JSON and recursively redacts sensitive context keys. | | |
| | `drift_quant.domain` | Defines immutable lifecycle, strategy version, signal, order intent, and risk-decision contracts. | | |
| ## Configuration | |
| Copy `.env.example` to a local ignored `.env` only if a local environment loader is added later. Environment values shown there are non-secret. Future provider code must obtain required credentials through `drift_quant.secrets.load_required_secret`; its validation errors and rendered values are redacted. | |
| ## Verification commands | |
| ```powershell | |
| uv sync --all-groups --locked | |
| uv run ruff check . | |
| uv run ruff format --check . | |
| uv run pytest | |
| ``` | |
| The commands are not evidence of success until their output has been observed. External-provider tests will be opt-in and are not part of this foundation. | |
