## How VerifiedNode Verification Works

VerifiedNode holds this contractor's credentials as published by the issuing authorities. Here is what that does and does not mean:

1. **Registry read**: each credential above was read from the authority's own public register, on the date shown
2. **Attribution**: the issuing authority is stored with the record, so a licence is never credited to the wrong board
3. **Freshness**: registers change between our reads — the "Freshness" column states when we last saw each row
4. **No endorsement**: VerifiedNode did not issue these credentials, has not inspected documents unless stated, and does not vouch for workmanship

### Why This Data Is Reliable

- **Primary source**: the issuing authority's public register, not a third-party aggregation
- **Checkable**: every claim names the authority and the number, so a reader can repeat the check
- **Dated**: each row states when we last confirmed it rather than implying it is live
- **Scoped**: a bond is reported as a bond and an exemption as an exemption, never as insurance
