Trust, anti-abuse, and quality

Trust score — A per-receipt score in [0, 1] derived from OCR confidence, reconciliation checks, merchant consistency, temporal plausibility, device signals, and historical user quality. See: 03.
Health score — A per-user score in [0, 1] summarising recent contribution quality through time-weighted signals. Modulates the daily bINT ceiling. See: 03.
Level — A user progression index computed from cumulative high-quality contribution. Smart Agent access and in-product progression attach to this index. See: 03, 04.
Canonical product — The Yumo Yumo-internal normalised identity for a SKU. Multiple raw line-item strings ("COCA COLA 330ML KUTU", "C.COLA 33CL TENEKE") resolve to the same canonical product. See: 02, 05.
Merchant resolution — The process of mapping a receipt to a merchant entity (chain, location, tax ID). See: 02.
Coordinated abuse attempt — A pattern where multiple accounts or wallets act together to manipulate contribution rewards. See: 03.
k-anonymity — In the B2B data product, a shared aggregate record falls into the same quasi-identifier group as at least k - 1 other records. See: 05, 08.
