Antigravity beats local LLM on file-aware office tasks

Antigravity with Claude Sonnet 4.6 Thinking outperformed local Qwen 3.5 9B Q4_K_M on office file tasks. Antigravity read folders before writing, matched naming and frontmatter schemas, and found cross-note themes. Qwen completed tasks but made more inference leaps and defaulted to vault root.
