What the evidence says — and does not say

What kind of figure?
CommitmentMoney, or a money-like promise, committed to a named recipient or project. The only role ever summed.
What has happened legally?
Partially disbursedSome of the money has been paid out.
Has money been paid?
Follow the payment evidenceThe source-linked current status records partial payment. It does not establish that the full stated amount was paid or that construction occurred.
What does it link to?
Project attributionOne registered project is linked directly to this row. The link alone does not prove the amount was paid or that the project advanced.

This is a commitment role, but the financial status still determines legal standing and payment. Funding and verified industrial outcomes remain separate. A financial record alone never independently verifies construction, commissioning or production. Read SMPT's counting and evidence rules.
