Why: - Final benchmark selected fixed_size with neighbor expansion ±3 as the winning Candidate. Changes: - Set neighbor_prev/neighbor_next defaults to 3 in Settings. - Default Query tab to fixed_size ±3/3 and Benchmarks to single-strategy fixed_size. Impact: - API and Dashboard runs use ±3 unless explicitly overridden. Co-authored-by: Cursor <cursoragent@cursor.com>
