Oleksandr Bezdieniezhnykh f46531fc6d Refine coding standards and testing guidelines
- Updated coding rules to emphasize readability, meaningful comments, and maintainability.
- Adjusted test coverage thresholds to 75% for business logic and clarified expectations for test scenarios.
- Enhanced guidelines for handling skipped tests, emphasizing the need for investigation and resolution.
- Introduced a completeness audit for research decomposition to ensure thoroughness in addressing problem dimensions.

# Testing
- Structure every test with Arrange / Act / Assert section comments using language-appropriate syntax (`# Arrange` for Python, `// Arrange` for C#/Rust/JS/TS)
- One assertion per test when practical; name tests descriptively: `MethodName_Scenario_ExpectedResult`
- Test boundary conditions, error paths, and happy paths
- Use mocks only for external dependencies; prefer real implementations for internal code
- Aim for 75%+ coverage on business logic; 100% on critical paths (code paths where a bug would cause data loss, security breaches, financial errors, or system outages — identify from acceptance criteria marked as must-have or from security_approach.md). The 75% threshold is canonical — see `cursor-meta.mdc` Quality Thresholds.
- Integration tests use real database (Postgres testcontainers or dedicated test DB)
- Never use Thread Sleep or fixed delays in tests; use polling or async waits
- Keep test data factories/builders for reusable test setup
- Tests must be independent: no shared mutable state between tests
