Public evidence register
How public claims map to engineering evidence
This page is the fact gate for everything published on the site. Only entries whose evidence status is “verified” may be stated in a definitive voice; everything else must be qualified or withheld.
Internal audit baseline
This register was updated from a release audit of the private product repository's main branch on 2026-07-16. The private source code is not disclosed because the marketing site is live; public pages give only checkable file responsibilities, boundary conclusions, and audit dates.
This is an internal engineering verification record. It is not equivalent to a third-party security audit, App Store review, or external certification.
