DepthSight Open Beta 0.3

Release Notes v0.3.0-beta

This release focuses on a deep architectural refactoring of the API and Celery integration layers, stabilizing the test suite by eliminating flaky test behaviors, and preparing the repository for continuous integration (CI/CD) with code coverage tracking.

---

Architectural Changes and Refactoring

• Circular Dependency Elimination: Celery/Redis configuration and environment variable loading have been decoupled from the API core and moved into a dedicated infrastructure layer (infra/config.py and infra/celery_app.py). This fully resolves the api.celery_app -> bot_module.config dependency cycle.
• Streamlined API Routing: Replaced the legacy ModuleProxy(lambda: depthsight_api...) implementation in endpoint definitions. Requests are now routed directly through explicit route submodules (api.routes.backtests and api.routes.diagnostics).
• Backward Compatibility: Retained a compatibility import layer to ensure existing tests and third-party integrations do not break.

Test Suite and CI/CD Stability

• Pandas 3.0 Compatibility: Resolved chained assignment warnings/errors (caused by inplace=True operations on Series copies) that left the ATR column populated with NaNs under new Pandas versions in the CI environment.
• Deterministic Strategy Builder Tests: Converted test_limit_retest_order and test_limit_break_signal_mode_and_entry_price from random walk candles to fully deterministic layouts with explicit stop-loss triggering to guarantee reliable local and remote runs.
• Isolated ML Model Tests: Added a module-level skip check to test_oracle_integration.py that bypasses the oracle test suite when the heavy ML weights file data/oracle_model.joblib is not checked into the repository (typical for headless CI runners).
• CI Environment Mocks: Configured mock values for environment-level secrets (JWT_SECRET_KEY, API_ENCRYPTION_KEY, API_KEY_SECRET) in conftest.py to prevent FastAPI bootstrap crashes during isolated pipeline stages.
• Isolated Test Strategy Registration: Registered VolumeBreakout and FakeBreakout strategies dynamically within the portfolio backtester test suite to keep test environments decoupled from production registry constraints.

Dependency and Coverage Management

• CI Python Runtime Upgrade: Upgraded the setup-python action version to 3.12 to mirror the production Docker container and fix package compilation issues on Python 3.13.
• Locked Dependencies: Pinned critical package versions (ccxt==4.4.89, redis==6.2.0, fakeredis==2.30.0) in requirements.txt to eliminate behavioral differences between development machines and Actions runners.
• Codecov Integration: Configured XML test coverage reporting (pytest-cov) and integrated the official Codecov GitHub Action to track code coverage stats on pull requests and commits.
