Pipeline Overview

• User enters text in the app and chooses whether to run grammar correction, punctuation correction, or both.
• The backend receives that request, validates the text, and decides which model stages to run.
• If both are enabled, grammar correction runs first to clean structure and word forms.
• The punctuation stage then runs on that cleaned text to place commas, periods, and other marks.
• The backend returns the final corrected sentence, plus lightweight metadata (like confidence/timing and whether each stage was used).
• The result is also saved so it can be viewed later in history/admin views.

Model Order (Simple Rule)

• Both on: Grammar -> Punctuation
• Only grammar on: Grammar only
• Only punctuation on: Punctuation only
• Neither selected: Falls back to punctuation so the request still returns a useful result
