 ## Log Sanitization
 
 Raw logs include full events and hundreds of event IDs per line, making them unwieldy for analysis. The sanitizer truncates long lines:

+### Retrieving Full Details from Raw Logs
+
+When sanitized logs show truncated messages (e.g., rejection reasons), use the raw log to see the complete content:

+```bash
+# Find specific error in raw log

+# View context around a truncated warning
+grep -A 2 -B 2 "pattern from sanitized log" "$RUN_DIR/sync-raw.log"

+The raw log contains complete, untruncated messages including full rejection reasons, event data, and debug details.
