When a draft is flagged by the Blue Team detector, the Coach parses the detected placement context, anchor text, and underlying detection reasons to generate targeted, constructive writing advice. Operating against a structured JSON schema and the system's anti-fluff editorial guide, it suggests surgical edits with precise original and replacement text strings. To protect document integrity, the engine strictly drops any edit where the original text does not match the draft verbatim, while tracking duplicate sentence occurrences to alert editors before applying changes.
