Jamie Pine fe14df5fda chore(backend): Ruff lint pass — deprecated APIs, exception leaks, dead patterns
Mechanical sweep of items called out in the PR review:

- qwen_llm_backend: AutoModelForCausalLM.from_pretrained(torch_dtype=…) is deprecated in transformers ≥4.41 in favor of dtype=. Renamed.
- routes/llm: try/except around backend.generate() raised HTTPException(500, detail=str(e)) which leaks stack traces / paths to clients and trips Ruff B904. Now logs the original exception server-side and hands the client a generic message; chained via `from e` to preserve traceback context.
- mcp_bindings + mcp_server/context: datetime.utcnow() is deprecated since 3.12. Switched the two assignment sites to datetime.now(timezone.utc). The schema-level `default=datetime.utcnow` defaults in database/models.py are left for a later schema-aware pass.
- routes/generations: `logger = …` sat between two import blocks (Ruff E402). Moved below imports.
- mcp_server/server + tests/test_refinement_samples: typing.Callable / typing.Iterable have been preferred-via collections.abc since 3.9 (Ruff UP035).
- routes/events: `except asyncio.TimeoutError` aliases plain `TimeoutError` since 3.11 (UP041).
- services/captures: hoisted WHISPER_NATIVE_FORMATS to module scope (was a function-local UPPER_SNAKE that tripped N806) and replaced the raw_path.unlink try/except OSError-pass with contextlib.suppress (SIM105). Semantic equivalence preserved — written_files.remove(raw_path) still only runs when unlink succeeds because it sits inside the suppressed block after the unlink call.
- database/migrations: hoisted the duplicate `import sqlite3` from inside two helper bodies to a single module-level import.

Backend Tests

Manual test scripts for debugging and validating backend functionality.

Test Files

test_generation_progress.py

Tests TTS generation with SSE progress monitoring to identify UX issues where users see download progress even when the model is already cached.

Usage:

cd backend
python tests/test_generation_progress.py

Prerequisites:

  • Server must be running (python main.py)
  • At least one voice profile must exist

test_real_download.py

Tests real model download with SSE progress monitoring.

Usage:

cd backend
# Delete cache first to force fresh download
rm -rf ~/.cache/huggingface/hub/models--openai--whisper-base
python tests/test_real_download.py

Prerequisites:

  • Server must be running (python main.py)

test_progress.py

Unit tests for ProgressManager and HFProgressTracker functionality.

Usage:

cd backend
python tests/test_progress.py

test_check_progress_state.py

Debugging script to inspect the internal state of ProgressManager and TaskManager.

Usage:

cd backend
python tests/test_check_progress_state.py

Notes

These are manual test scripts, not automated unit tests. They're designed for:

  • Debugging progress tracking issues
  • Validating SSE event streams
  • Monitoring real-time download behavior
  • Inspecting internal state during development
