[akisma]

Priority: P1 - High
Estimate: 6 days
Dependencies: #57

Product Acceptance Criteria (Customer Value)

User Story: As a chef, I want the app to remember commonly added items and offer clarification when there are ambiguous matches, so that I can quickly add the right products using speech.

Acceptance Scenarios:

• Save New Items:
  Given a new item added by speech,
  When the item does not exist in the database,
  Then the system saves it as a common item for future use.
• Disambiguation Dialogue:
  Given multiple matches for an item name,
  When I add an item by speech,
  Then the system asks for clarification (e.g., "whole milk or skim milk?") and confirms my choice verbally and visually.
