MOSAIC-Retrieval v1.0.0

MOSAIC-Retrieval v1.0.0 is a sanitized public portfolio snapshot for audited image/video-text retrieval.

Highlights:

• COCO External Final: image-only Text-to-Image adapter R@1 0.5019 -> 0.5309 (+2.89 pp, 95% CI [+2.00, +3.92]).
• MSR-VTT-1K-A: temporal aggregation T2V R@1/R@10 0.304/0.631 -> 0.335/0.710.
• Static synthetic GitHub Pages workbench, FastAPI/FAISS serving contracts, 44 public tests, and wheel smoke across Windows/Linux.
• No raw COCO/MSR-VTT media, captions, query-level rankings, model weights, derived features, or indexes are redistributed.

The published metrics are offline protocol-bound evidence, not SOTA, production SLA, online A/B, or business-impact claims.
