## Task
|
|
Implement the Nougat formula-only adapter boundary.
|
|
|
|
The adapter should accept formula candidates and return LaTeX candidates or structured failure results. It should support a configured Nougat command path and be mockable in unit tests.
|
|
|
|
## Sprint Contract
|
|
- Done means: Nougat execution is isolated behind a testable command adapter and never becomes the primary document parser.
|
|
- Hard thresholds: failures preserve Marker fallback text; tests do not require GPU/model execution by default; command path handling works on Windows.
|
|
- Files owned: `src/pdftomd/formulas.py`, optional `src/pdftomd/nougat_adapter.py`, tests, `PROGRESS.md`, phase index.
|
|
- Dependencies: Step 0 formula candidates and Phase 1 options.
|
|
|
|
## Acceptance Criteria
|
|
```powershell
|
|
python scripts\validate_workspace.py
|
|
.\venv\python.exe -m pytest tests
|
|
```
|
|
|
|
## Verification
|
|
1. Run the acceptance commands.
|
|
2. Confirm `.\venv\Scripts\nougat.exe --help` remains documented as an environment check, not a unit-test requirement.
|
|
3. Update `PROGRESS.md` and this phase index.
|
|
|
|
## Do Not
|
|
- Do not parse whole PDFs with Nougat.
|
|
- Do not require model downloads for normal unit tests.
|
|
- Do not discard Marker source text on failure.
