Tasks
Collect ecommerce catalog data
A collector that survives production is slow to scale and strict about location tags. Keep parsers in your repo. Premip only terminates the proxy.
Golden samples
Save HTML for one PDP per market. Parser tests should fail when the storefront redesigns.
Session policy
Stay sticky through a category walk. Rotate after the batch if the next cycle should use a new IP.
Politeness
Cap concurrency. Treat block pages as stop-the-line events, not as empty prices.
Instructions
1. Canary PDP
Fetch through the chosen product and location.
2. Lock the parser
Commit tests against the sample.
3. Walk one category
Confirm row counts and miss rates.
4. Clone markets
New location, same spider, tagged output.
