# Refactor: DevRank Spider Checkpointing

Implement incremental saving in the `Spider` service to prevent data loss during long discovery runs.

**Changes:**
- `Spider.mjs`: Save `tracker.json` (candidates) and `visited.json` (graph) after processing every page of search results (or every N repositories).
