[konradjerrybarrek]

PR Summary: feat/01 → main

What changed

app/models.py — new file
Extracted all Pydantic models (TaskStatus, DeveloperTask, ProductivityReport) from main.py into a dedicated models file, satisfying the mandatory coding guideline requiring models to live in app/models.py.

app/main.py — refactored & bug fixes

• Imports models from app.models instead of defining them inline
• Fixed bug: generate_productivity_report was counting PENDING tasks as completed — now correctly counts COMPLETE
• get_status converted to async def with explicit -> dict return type
• log_task now returns a DeveloperTask model (was returning an f-string), uses model_copy for immutable update, and has response_model on the decorator
• Added new GET /task/{task_id}/status endpoint

tests/ — new test suite

• tests/conftest.py: shared async client fixture using httpx.AsyncClient + ASGITransport
• tests/unit/test_main.py: 8 unit tests covering fetch_all_tasks and generate_productivity_report
• tests/integration/test_main.py: 10 integration tests covering all endpoints (happy path, validation errors, model validation)

.github/prompts/ — new custom prompt

• Added logs-audit.prompt.md: reusable /logs-audit prompt for production logging reviews
