LLaVA auxiliary subset (1008 rows)

This repository contains the deterministic Understanding-auxiliary view used by the current four-family umm-sft paired_ug_formal recipes.

  • Rows published: 1,008
  • Historical bounded source pool: 16,000 rows
  • Verified rz6000 replica used to reconstruct that pool: 100,547 rows
  • Pool construction: first 16,000 rows of the verified row-ordered builder output
  • Selection seed: 178430
  • Selection details: formal_selection_receipt.json
  • Features: prompt, image, completion

Only the 1,008 rows consumed by the formal source contract are published; the 100,547-row replica is not. The source metadata did not declare a license; other is only a metadata placeholder, and users must follow the original source terms.
