- Resolved Ruff E402 warnings by moving module docstrings ahead of `from __future__ import annotations` across currency and pricing service modules, dropped the unused `HTTPException` import in `monitoring/__init__.py`, and confirmed a clean `ruff check .` run. - Resolved Ruff E402 warnings by moving module docstrings ahead of `from __future__ import annotations` across currency and pricing service modules, dropped the unused `HTTPException` import in `monitoring/__init__.py`, and confirmed a clean `ruff check .` run.
- Enhanced the deploy job in `.gitea/workflows/cicache.yml` to capture Kubernetes pod, deployment, and container logs into `/logs/deployment/` for staging/production rollouts and publish them via a `deployment-logs` artifact, updating CI/CD documentation with retrieval instructions. - Enhanced the deploy job in `.gitea/workflows/cicache.yml` to capture Kubernetes pod, deployment, and container logs into `/logs/deployment/` for staging/production rollouts and publish them via a `deployment-logs` artifact, updating CI/CD documentation with retrieval instructions.
- Fixed CI dashboard template lookup failures by renaming `templates/Dashboard.html` to `templates/dashboard.html` and verifying `tests/test_dashboard_route.py` locally to ensure TemplateNotFound no longer occurs on case-sensitive filesystems. - Fixed CI dashboard template lookup failures by renaming `templates/Dashboard.html` to `templates/dashboard.html` and verifying `tests/test_dashboard_route.py` locally to ensure TemplateNotFound no longer occurs on case-sensitive filesystems.
- Implemented SQLite support as primary local database with environment-driven backend switching (`CALMINER_USE_SQLITE=true`), updated `scripts/init_db.py` for database-agnostic DDL generation (PostgreSQL enums vs SQLite CHECK constraints), tested compatibility with both backends, and verified application startup and seeded data initialization work seamlessly across SQLite and PostgreSQL.
