Summary

The SERP API result cache TTL is hardcoded to 24 hours. This cannot be tuned without code changes.

Work to do

  • Add SERP_CACHE_TTL_HOURS to config.py with a default of 24.
  • Update the cache logic to read the TTL from config.
  • Document the variable in .env.example.

Acceptance criteria

  • Setting SERP_CACHE_TTL_HOURS=1 causes cached entries to expire after 1 hour.
  • Unset variable defaults to 24 hours with no behaviour change.
  • No hardcoded 24 hour literal remains in the cache code.

Already resolved. config.py line 46: serp_cache_ttl_hours = int(os.getenv("SERP_CACHE_TTL_HOURS", "24")). Used in analyzer.py line 73: ttl_hours=config.serp_cache_ttl_hours. Documented in .env.example. Closing.
