The checksum identifies the exact bytes of the document read. It does not prove that its claims are correct.

1. 18 pages connect products, the journal and enquiries

   The register covers the home page, product areas, contact, legal pages and six journal articles.

   Boundary: The website establishes digital presentation. Sound quality and amplifier performance require separate verification.

2. Enquiries are stored independently of website releases

   Each enquiry receives an identifier and is stored outside the replaceable website directory; notifications use a persistent retry queue.

   Boundary: A queue does not guarantee every email will arrive. The 20 September record confirms a control delivery on that date.

3. A verified file set is switched as one release

   The new directory is checked before switching; the previous release remains available for recovery.

   Boundary: This manages change without promising the absence of all failures.
