/**
* Smoke tests for web_search.ts — ADR-135
*
* All tests are mock-based using webSearchTestHooks for ESM-safe injection.
* NO live API calls are made.
*
* Coverage:
* 1. resolveGoogleCustomSearchCredentials — env var path
* 2. resolveGoogleCustomSearchCredentials — returns null when creds missing
* 3. searchGoogleCustomSearch — parses items correctly (unit parse test)
* 4. searchGoogleCustomSearch — throws on API error object in response
* 5. searchWikipedia — strips HTML from snippet
* 6. WebSearchTool.execute — Google creds present → Google used first
* 7. WebSearchTool.execute — Google creds absent → Wikipedia used
* 8. WebSearchTool.execute — Google throws → falls back to Wikipedia
* 9. WebSearchTool.execute — Google 0 results → falls back to Wikipedia
* 10. WebSearchTool.execute — Google + Wikipedia both fail → DDG used
* 11. WebSearchTool.execute — rejects empty query
* 12. WebSearchTool.execute — max_results capped at 10
*
* Run with: npx tsx web_search.smoke.ts (from gaia-tools directory)
