Letsbegin/CHANGES2.md
Implemented the safe round-2 fixes and wrote `CHANGES2.md`. Changed: - Moved Ralph Gemini key validation into the Gemini-only path so default Ollama runs work without Gemini env vars. - Added 400 invalid-JSON guards to the five missed POST routes. - Added `CHANGES2.md` with applied fixes and deferred items. Per your constraints, I did not run git, installs, or tests.
