The claim [[claim-hnc-falcon-fraud-manager-became-fico-infrastructure]] carries a
headline reach statistic that currently rests only on a Tier-3 venue
(Machine Learning Times / Predictive Analytics World):

> "Neural network models created by FICO score a majority of both the credit and
> debit card transactions in the world today."

Per the sourcing floor (`00-meta/sources.md`), any specific quantitative claim —
"a majority," "two-thirds," an "Nx" share — requires a Tier 1–2 primary. This
one does not clear the floor and is flagged `[unverified-quant — needs primary]`.

## Why it matters

It is the load-bearing payoff of the whole "connectionist commercial exit"
thread: if true, a written-off 1980s neural-net paradigm now scores the majority
of global card payments — an enormous, uncredited footprint. If it is a garbled
marketing figure (e.g. conflating "cards protected" with "transactions scored,"
or a US-only figure inflated to "the world"), the payoff weakens considerably.

## What would answer it

- **FICO primary material** — FICO annual reports / 10-K filings, or FICO's own
  Falcon product documentation, stating the share of card transactions its
  Falcon/neural models score, with a defined denominator (US vs. global; credit
  vs. debit; accounts vs. transactions).
- An **independent audited or analyst figure** (Tier 1–2) corroborating the
  "majority of the world's" framing rather than the softer, more commonly cited
  "two-thirds of US card transactions" phrasing.
- Resolve the denominator ambiguity: the same lineage is elsewhere quoted as
  "two-thirds of *all card transactions*" (the source URL's own title) versus
  "a majority of the world's" — these are not the same claim.

Until then, the note stays `status: seedling` with the flag preserved.
