THI is Arzenal’s local personal-trend indicator. The deterministic tHiX™ algorithm combines recent, authorized signals only when enough evidence exists.
The Human Index is a 0–100 personal trend indicator built into Arzenal. Version tHiX-1.2.0 is deterministic: the same eligible inputs, time, and time zone produce the same result without AI or a network call.
A missing score means unavailable, not zero. The algorithm waits until at least two independent dimensions and sufficient weighted coverage are present.
Recent authorized sleep signals, with eligible manual sleep as fallback.
Authorized step and exercise-minute summaries from Health Connect.
Focus, energy, mood, completed focus sessions, and bounded caffeine context.
Consistency across due, completed, and skipped routine actions.
tHiX™ validates local inputs, integrates recent history with a 3.5-day half-life, and applies a bounded momentum adjustment before composing the index.
The user chooses which local records and Health Connect permissions Arzenal may use.
tHiX™ checks permission, freshness, valid ranges, and the exact seven-day observation window.
Eligible signals are transformed into comparable 0–100 values with product-specific bounded curves.
Four dimensions use recency-weighted history, coverage, confidence, and bounded momentum.
THI emits a score when evidence is sufficient, plus status, confidence, coverage, missing signals, and algorithm version.
Unavailable, Emerging, or Established
How strongly the available evidence supports the result
How much of the configured signal surface is represented
Stored with every optional history row to prevent false trend comparisons
The implemented tHiX™ calculation makes no network call and uses no AI. The result is not uploaded. Optional one-row-per-day history is local, default-off, versioned, and independently deletable.
THI does not measure human worth, character, discipline, fitness, or productivity. It is not a diagnosis, prognosis, treatment recommendation, medical-device output, or substitute for professional care.
It must not be used for employment, insurance, eligibility, ranking people, or other consequential decisions. A higher number means only that the eligible inputs map to a higher value under this documented version of Arzenal’s product heuristics.
CodenameStranding contains the versioned data contracts, pure calculation use case, golden-vector tests, local history repository, database migration tests, Home tile, Insights route, reusable gauge, and Wear OS Human Index surfaces.
The Gamer Index uses separate dimensions and mathematics to describe a player’s evolving gaming-performance profile.
A bounded personal trend for Arzenal, not a clinical or human-value score.
