Summary

The SERP result cache TTL is hardcoded to 24 hours in config.py. Operators cannot tune this without editing code.

Work

  • Add SERP_CACHE_TTL_HOURS to config.py with a default of 24.
  • Replace the hardcoded value in the caching logic with the config value.
  • Document the variable in .env.example.

Acceptance Criteria

  • Setting SERP_CACHE_TTL_HOURS=1 causes cache entries to expire after 1 hour.
  • Unsetting the variable defaults to 24 hours.
  • .env.example documents the variable.
