 ### Task 4: Implement cache-aware search results with TTL policies
-- [ ] Integrate search result caching using existing cache TTL policies (near-term: 2-6h, far-term: 7d)
-- [ ] Add cache lookup before on-demand /search calls
-- [ ] Write tests for cache hit/miss with lazy expansion
-- [ ] Write tests for TTL policy selection based on date distance
-- [ ] Run tests - must pass before task 5

 ### Task 5: Verify end-to-end lazy routing and update documentation
-- [ ] Verify all requirements from Overview are implemented
-- [ ] Verify edge cases: closed station fallback, depth limits, cache behavior
-- [ ] Run full test suite (unit tests)
-- [ ] Run linter - all issues must be fixed
-- [ ] Update this plan file when scope changes during implementation
-- [ ] Update README.md if new patterns discovered
