- Track laplacian blur score through quality filtering pipeline (quality.py: blur_score on QualityResult; diversity.py: store on asset; executor.py: read via quality_score key) - Replace per-file polling with post-person batch reconciliation: after all uploads for a person complete, poll Frigate (up to 15s) until the expected number of new files appear, then map by filename timestamp order (Frigate FIFO queue = upload order = timestamp order) - Document race condition limitation: concurrent external uploads cause the batch to be skipped entirely (safe but files go unmapped); noted in code as requiring a Frigate API fix (return filename on upload) - Add two assess_quality integration tests for blur_score Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
