Why aggregate-only cards were retired from the quotable path

2026-09-14 · Council of AI (CSOAI Ltd)

Since the 2026-09-13 evidence ruling, a Hub card without item evidence cannot land as quotable; older cards are superseded, not deleted.

Since the 2026-09-13 evidence ruling, a Hub card that carries just an aggregate accuracy cannot enter the quotable path. The landing script, scripts/land_mill_cards.py, says it plainly: an aggregate-only card is never quotable; a card that binds an evidence bundle must find it, and a bundle that is absent or hashes differently fails closed; and cards with no evidence bundle are skipped with the reason that aggregate-only cards stopped landing after the 2026-09-13 evidence ruling. Older cards are not deleted. When a current card with item evidence replaces one, SUPERSEDED.jsonl records it with the reason "#2075: replaced by a current reproducibly admitted v0.2 item-evidence card". The Hub cards index describes its source as reproducibly admitted signed Hub cards on the deployed commit, and publishes how many signed files it saw and how many it skipped, so the retired population stays countable without being quotable. The reason is reproducibility: an aggregate cannot be re-graded, and item rows can.
