Verify navigation-data updates before bridge installation
Can bridge staff prove the update source, content, approval, and target system while offline?
Operational pain
Charts and navigation updates travel through portals, agents, removable media, and shipboard systems where provenance can be separated from the file.
Trigger
Scheduled chart update, vendor certificate change, or navigation-data integrity alert.
QNSI contribution
Connect the decision to a controlled security path
Bind QNSI-supported signature metadata to update digest, publisher identity, vessel entitlement, validity, and bridge acceptance.
Decision artifact
An offline-verifiable navigation update manifest with signer chain, expiry, target version, and installation record.
What still requires validation
The operator confirms authorized publishers, equipment compatibility, navigation safety, media control, and fallback.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
