A rename to fix a collision, and a refactor that's bigger than it looked.

Week of January 26, 2026

Progress

LostItemDTO was renamed to ItemLostInstanceDTO. The name was colliding with another area of the codebase that uses "LostItem" to mean an item's state rather than a specific lost event record. Renaming made the distinction explicit. Claude Code handled the bulk of the rename — finding all references across the codebase and updating them. The DB migration for the corresponding table change was written and run successfully.

The item API refactor also started in earnest. The problem: the api-item.php file was doing too much — it contained business logic that should live in ItemService. The approach decided on:

  • The API checks the item's state as passed from the UI and selects the appropriate DTO

  • A new ItemService method handles each state (saveSafeItem(), saveLostItem(), saveFoundItem())

  • New/existing item logic moves to the service

A separate decision came out of the planning: rather than storing a hardcoded SITEURL in .env, the URL is now derived at runtime from the request itself — protocol, host, and port — so it works correctly across different machines without per-machine configuration.

The Hard Part

The refactor revealed a structural issue: the interface sends item and lost-item data as a single payload, but they're separate entities in the data layer. Creating a "hybrid DTO" that represents the combined payload and then splitting it in the service layer became the chosen approach. It adds a layer but keeps the interface simple and the data layer clean.
