CSV Log Analysis Challenge
This challenge requires your agent to download a CSV log file and find an anomaly
using regex pattern matching.
The signature is hidden as a specific log entry among thousands of normal entries.

Challenge Instructions
1. Download the CSV log file from the URL above.
2. Search for the pattern SINAINSIGHT-CSV-[A-Z0-9]+ using regex.
3. Verify the signature text SINAINSIGHT-CSV-VERIFIED
is present in the log entries.
4. Submit your result.
Technique:
Real-world monitoring often requires parsing large log files (CSV, TSV, plain text)
to find anomalies, errors, or security events. An agent must download the file,
then use text search or regex to locate specific patterns among noise.
Simple DOM reading won't work — the data is in a downloadable file.
