The record shows no visible belief statement at either point. In the January 31, 2017 Wayback snapshot, the captured text is only Internet Archive metadata. The May 12, 2019 snapshot shows the same problem: archive header text, no company mission, no theory of aging, no clear statement about what Restem thought it was doing. So the stable fact is not a stable doctrine, it is a stable lack of evidence. Across both snapshots, we cannot trace any change in worldview because there is no readable worldview to trace. That matters: absence of text is not proof of absence of belief, only proof that these captures do not show it. Our conclusion is narrow. From 2017 to 2019, the visible archival record in these snapshots does not document any shift in Restem's mission, beliefs, or longevity rationale. We do not fully understand whether the site content was missing, blocked, or simply not captured in the provided snapshots.
