Top Stack Recommendation

Updated February 28, 2026

Top stack recommendation is the highest-priority stack signal after current context and safety filters.

Why it matters

Ranking shifts as behavior and safety signals change.

What drives ranking

Top stack vs top single ingredient

A top stack includes compatibility and scheduling considerations across multiple ingredients.

A top ingredient may still appear as a standalone alternative when stack complexity is too high.

Confidence and use caveat

Top ranking can still be wrong for an individual, especially with sparse or delayed logs.

Use confidence and rationale context before changing protocol.

Practical action step

If a top stack repeatedly fails your goals, request a narrower alternatives view and simplify one dimension before escalation.

Uncertainty and limits

Cross-site references

How this appears in Unfair

Top stack labels reflect combined signal strength and active constraint checks for your current cycle.

Clinical safety note

Do not prioritize ranking over warning signals or clinician-guided contraindication changes.
