Risk: 78/100 - medium

The cache is global and query-only, so repeated searches can return stale results across different scopes or datasets, and the new test does not verify caching behavior.

Main concerns

• high / risky_refactor apps/client/src/search-utils.ts: performSearch now reuses results solely by query string, ignoring scope and input data changes, which can return stale or incorrect results for different sessions/projects.
• medium / weak_test apps/client/src/search-utils.test.ts: The new test only checks that results are truthy and does not assert that cached results are reused or that the cache respects scope and data differences.
• medium / unrelated_changes apps/client/src/search-utils.ts: A debug console.log was added inside the search loop, which changes runtime behavior and can spam client logs unrelated to caching.

Review first

• apps/client/src/search-utils.ts
• apps/client/src/search-utils.test.ts
