Overview

Thread-safe, file-persisted error tracker for the dev dashboard Error Tracker panel.

Errors are stored in a JSON file in the system temp directory keyed by project path, so they survive across requests and server restarts. Duplicate errors (same type + message + file + line) are de-duplicated —the count increments and the entry is re-opened if it was resolved.
