ALTERED BRILLIANCE IS LIVE.

DETERMINISTIC HUMAN CONTEXT / tHiX™

The calculation behind The Human Index.

tHiX converts recent, authorized routine and wellbeing context into an explainable personal trend inside Arzenal. Local-first, versioned, and intentionally bounded.

PRODUCT + ALGORITHM + INDEX

Arzenal holds the context. tHiX calculates. THI makes the result legible.

ARZENAL

The local-first product surface

Routines, focus, sleep, fasting, user-entered context, and optional read-only device signals.

tHiX™

The deterministic calculation

Validation, normalization, recency weighting, evidence coverage, confidence, and versioned composition.

THI

The Human Index

A 0–100 personal trend with status, confidence, coverage, missing signals, and history boundaries.

EXPLAINABLE WEIGHTS

Four evidence streams, never one opaque score.

Recovery

30%

Recent authorized sleep context, with eligible manual sleep used as a bounded fallback.

Movement

25%

Authorized steps and exercise-minute summaries from supported Health Connect records.

Mental Readiness

25%

Focus, energy, mood, completed focus sessions, and bounded caffeine context.

Routine Engagement

20%

Consistency across due, completed, and skipped routine actions.

SEVEN-DAY WINDOW

Freshness, sufficiency, then composition.

The current version uses recent evidence with a 3.5-day half-life. If fewer than two independent dimensions or insufficient weighted coverage exist, the result stays unavailable rather than inventing certainty.

  1. 01

    Authorize

    The user chooses which local records and optional Health Connect permissions Arzenal may use.

  2. 02

    Validate

    tHiX checks freshness, valid ranges, permission state, and the exact seven-day observation window.

  3. 03

    Normalize

    Eligible signals become comparable 0–100 values using bounded, versioned product curves.

  4. 04

    Integrate

    Four dimensions combine recency-weighted history, coverage, confidence, and bounded momentum.

  5. 05

    Return THI

    When evidence is sufficient, tHiX returns The Human Index with status, confidence, coverage, missing signals, and version.

LOCAL-FIRST BY DESIGN

The calculation stays with the user.

tHiX makes no network call and uses no AI. The current result is not uploaded. Optional local history is default-off, versioned, independently deletable, and limited to one row per day.

SEPARATE MATHEMATICS

tHiX is not tGiX renamed.

tGiX structures gaming evidence for TGI, The Gamer Index, inside Altered Brilliance. tHiX uses independently designed dimensions and mathematics for THI, The Human Index, inside Arzenal.
