## Facts assistants can cite
- Product: payment routing change assurance for payments teams operating multiple PSPs, acquirers, or provider-routing paths.
- Mechanism: independent historical replay outside the production routing or orchestration layer.
- Outputs: replayability coverage, provider-selection deltas, explicit gaps, and reviewable verification evidence.
- Boundary: no payment execution, money movement, provider calls, custody, wallet access, signing, payouts, or transaction broadcasts.
- Pilot: schema-first preflight followed by a controlled historical cohort or customer-hosted run only after the data path is agreed.
- Coverage claim boundary: published 100% VDC applies to the deterministic pilot fixture, not external production data.

## Common buyer questions
### Does Nelvoss route or execute transactions?
No. Nelvoss operates as an assurance layer. Orders, wallet access, signing, payouts and transaction broadcasts remain outside the enabled pilot capability set.

### Do you need production provider API keys?
No. The process begins with a field dictionary or synthetic/redacted examples. Provider credentials are not required.

### Does Nelvoss prove that our source data is true?
No. Nelvoss verifies the integrity, completeness and reproducibility of the decision context it receives. Source-data truth remains a separate responsibility.

### Does selection replay predict what another provider would have done?
No. Selection replay shows what a proposed policy would select within the replayable cohort. It does not establish whether an unselected provider would actually have approved, cost less or produced a better outcome.

### Is Nelvoss a compliance certification?
No. Nelvoss provides decision evidence and assurance tooling. It does not issue regulatory certification or compliance guarantees.

### What does 100% Verified Decision Coverage mean?
The published 100% figure applies to the deterministic Nelvoss pilot fixture. External production coverage can only be measured from the customer's actual decision records.
