Walkthrough: Price Extraction & Catalog Fixes

1. Vision Priority Strategy

Problem: The AI was prioritizing text data (often hidden/outdated) over the visual price on the screenshot, extracting incorrect prices (e.g. 0.99€ instead of 1.27€).

Solution:

• Prompt Engineering: Rewrote the system prompt in ai_schema.py to explicitly declare the IMAGE AS THE SOURCE OF TRUTH.
• Logic Fix: Disabled the AIPriceExtractor (Text-only AI) in scheduler_service.py which was short-circuiting the logic before the Vision AI could run.

2. Catalog Scraper Fix

Problem: Catalogs were not updating because the browserless service was failing (likely blocked or network issues), preventing the scraper from loading cataloguemate.fr.

Solution:

• HTTP Fallback: Modified cataloguemate_scraper.py to use a robust fallback mechanism.
  • First attempts to use the secure Browserless browser.
  • If that fails, it instantly falls back to a standard httpx HTTP request, which is often sufficient for static catalog sites.

3. Cleanup

• Removed 20+ temporary debug/verification scripts (debug_*.py, verify_*.py) from the root directory to keep the production environment clean.
