Evidence Anchor
BioHarmony 5.9/10
Exogenous ketones earn a 5.9 / 10, worth trying, but only for a person whose goal matches the narrow slice of evidence that is actually real. They are fast, intrinsically safe, and fully reversible, and there are genuine signals in heart-failure hemodynamics (Nielsen et al. 2019) and training-overload tolerance (Poffe et al. 2019). The score is held down, not by danger, but by the combination of a null endurance literature (Brooks et al. 2022), a high price with no way to amortize it, and an acute-only effect that produces no lasting adaptation. The tier is justified because the upside is real but narrow and the main cost is value, not harm. ✅ Best for: Heart-failure patients exploring hemodynamic support under cardiology supervision inside a trial or specialist setting, where the strongest signal lives. Endurance athletes in a heavy training-overload block who want better training tolerance, not race-day speed. People who want a fast, controllable acute appetite or blood-glucose blunting tool before a meal, with realistic expectations. Biohackers who value reaching a ketotic blood state in under an hour without days of dietary adaptation. Anyone who has read the meta-analysis and wants to self-experiment with clear endpoints and a stop rule, accepting the cost. ❌ Avoid if: You are a healthy athlete expecting an endurance-performance edge, because the pooled evidence shows none and one trial showed impairment. You want a brain or Alzheimer's intervention, since that evidence is medium-chain triglycerides and ketogenic diets, not ketone esters. You take insulin or sulfonylureas without accounting for additive glucose lowering, or you have type 1 diabetes and rely on ketone readings to detect ketoacidosis. You are price-sensitive, since esters cost about $30 per dose with no carryover. You cannot tolerate the taste or the GI effects, which are common enough to derail consistent use.

My score and my verdict: one signal of three, never the whole answer.
Momentum
Signals begin with Edition 2
Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.
Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.

The score anchors the ring; the other five drive momentum, which can nudge the ring by one step at most. How placement works.
