[Codeward] Auto-fix: 1 security finding on run #219

[codeward-code-review-agent]

Codeward auto-generated this fix from real findings on run #219 (security agent).

Changes

• LiveEditFronten/services/gemini.ts — Removed hardcoded VITE_GEMINI_API_KEY references from client-side code. Line 7 now references process.env.GEMINI_API_KEY (server-side), and line 35 now proxies the video download through a backend endpoint instead of appending the API key to the fetch URL. (208 -> 211 lines)
  • Verified: typecheck (no new errors vs baseline of 0)

Findings

• INFO Removed hardcoded VITE_GEMINI_API_KEY references from client-side code. Line 7 now references process.env.GEMINI_API_KEY (server-side), and line 35 now proxies the video download through a backend endpoint instead of appending the API key to the fetch URL. (security) - LiveEditFronten/services/gemini.ts

---

Diff verification: The changes are minimal and correctly scoped:

• Line 7: Replaced import.meta.env.VITE_GEMINI_API_KEY with process.env.GEMINI_API_KEY
• Lines 35-38: Replaced direct fetch with API key appended to URL with a POST to ${BACKEND_URL}/api/download-video that proxies the download server-side
• Removed 1 blank line at top of file
• Updated comment to reflect server-side handling

No unrelated changes. No visible correctness regressions. Typecheck passed (0 errors baseline maintained).
