Findings

Existing Local Context

• ~/Code/video_recognition_local/store_dwell_alert exists, but it tracks people dwell time, not food batch dwell time.
• The new project should be independent and should not share git history with the existing project.

Domain Model

• The reliable business unit is a display-zone batch, not an individual food item.
• A batch starts when a zone changes from empty to occupied.
• A batch continues while the zone remains occupied, even if the item count decreases.
• A batch ends when the zone becomes empty.
• If a batch is removed after the maximum dwell threshold, the system expects a trash-bin deposit event within a configurable window.
• If a removed over-threshold batch reappears in any display zone before being discarded, that is a violation.
• If food is added while a zone is already occupied, that is a mixed-batch violation.
