Overview
How Change Detection Caught a Site Redesign Before the Pipeline Broke
Clearpath's competitor-monitoring pipeline kept working the same day a tracked site shipped a full redesign—because change detection flagged the shift before it reached production exports.
What happened
A competitor's product page structure changed overnight. The crawl still returned HTTP 200, but the extracted price field came back empty on several products—exactly the pattern soft-block and low-confidence-field detection is built to catch.
What caught it
- Per-field confidence scoring flagged the price field as low-confidence instead of silently accepting a blank
- The change event showed up in the site's monitoring feed the same day
- Downstream price-conflict automation paused for that source until the extraction was confirmed correct
Takeaway
The team could show exactly when the source changed and why the pipeline didn't silently propagate bad data—instead of discovering it a week later in a stakeholder report.
