caption text policy: verbatim — captions are published byte-identical to the internal corpus; only the images path is rewritten. Sensitive rows are handled by exclusion (config pii_free), never by editing text.
rows counted: 454,963
These strings are text visible inside the public source images (business cards, storefront signage, screenshots, classified ads). They are also what OCR-heavy evaluation rewards, so they are measured here rather than rewritten in place.
