There were rules. He treated information like a borrowed vase. Never break it. Never tell the whole provenance unless asked. Keep the owner’s name separate from the pattern. He developed a ritual: before he touched a dataset he whispered the letters of its origin, tracing them like incantations — "db, db, db" — and imagined the shapeshift of people into rows.

That gratitude lodged itself in him as if it were currency. He began to see the people behind his rows as more than hypotheses. He started to build private indices of things that couldn't be monetized: the way Mr. Patel from the bakery humms whenever frosting is applied; the pattern of hello messages that meant "I need help" when typed in broken English; the list of children who sat in back seats and watched the same streetlight blink at 2:13 a.m. He called these caches "small safekeepings."

One spring, a dataset arrived that broke his rules cleanly: a file of medical records from a hospice, a mass export that should never have been public. The records contained not just names but notes: a daughter's brief flurry of hopeful messages, a father's tired jokes, a nurse's careful handwriting about medication. He could have anonymized and published patterns that might help researchers; he could have alerted the oversight board; he could have closed it and left. Instead, he read. He read the final texts parents sent to dying children, the shopping lists turned into instructions, the quiet arithmetic of what to keep and what to let go. It felt like standing at the edge of a private sea.
