A longevity protocol is a stack architecture template for tracking slow-moving healthspan-adjacent proxies across a long review window with conservative changes. It is not a promise to extend lifespan; it is a way to avoid judging slow biomarkers and fitness markers on short-term noise.
Why the review window is longer
Longevity-oriented goals usually depend on markers that move slowly or require scheduled testing. A protocol therefore starts with the blood biomarker panel, fitness proxy, or other objective measure that will actually be reviewed.
The stack is then held stable long enough for the chosen proxy to be measured again. Short mood shifts or a better week of sleep may be useful context, but they are not enough to declare the protocol successful.
Stack shape
The roster should be conservative. Core items are stable, familiar, and low burden. Optional items enter one at a time with a reason, a review date, and a stop rule.
This follows the broader stack composition principle: a stack is judged by role, timing, and reviewability, not by the number of plausible mechanisms attached to it.
Proxy pair
The primary proxy might be a lab marker, vo2 max estimate, resting heart rate trend, or another objective proxy that matches the user's goal. A secondary proxy protects against a narrow interpretation, especially when the primary marker can move for reasons outside supplementation.
The protocol records context around training, sleep, illness, medication changes, and diet changes so the review does not pretend the stack was the only variable.
Review rules
The review begins by asking whether the comparison is valid. Was the same marker measured in a comparable state? Did a medication, diagnosis, illness, or major lifestyle change occur during the block? Was adherence high enough to read?
If the answer is no, the protocol extends or resets the block rather than forcing a ranking decision.
How this appears in Unfair
In Unfair, a longevity protocol would prefill slow-proxy tracking, longer review prompts, and conservative optional-item rules. The app would frame the result as a change in monitored proxies, not as a lifespan claim.
Clinical safety note
A longevity protocol can overlap with medical risk markers. Out-of-range labs, new diagnoses, medication changes, or concerning symptoms should be reviewed with a clinician before the stack is changed or continued.
