Define and Document Item History & Location Logic

[vivjd]

Goal:
Formalize how ItemHistory determines an item’s current location.

Tasks:

• Identify events that update true location (INITIAL, ARRIVED, VERIFIED, CORRECTION)
• Identify workflow-only events (MOVE_REQUESTED, MOVE_APPROVED, MOVE_REJECTED)
• Write algorithm for get_current_location(item_id)
• Document the rules with example transitions

Acceptance Criteria:

• Logic clearly documented and approved by team
• Example flows yield expected results
