  "method": {
    "probability": "qAdjusted = -expm1(log1p(-qBase) * multiplier). qBase is the pinned country/sex/calendar-year UN life-table qx; exact 0 and 1 are preserved. The same per-life/year RNG draw is compared to qAdjusted.",
    "condition": "Both the actual reserve and a choice-neutral reference reserve receive the identical natural-aging/random change. Only actual reserve receives accepted recovery/strain choices. Interpolate log relative risk across the declared game reserve anchors, then divide actual RR by reference RR. This avoids charging ordinary aging twice. Reserve anchors, interpolation and points are game assumptions; they are not measured health-score cutoffs.",
    "activity": "An unrecorded routine is neutral. Explicit regular/inactive routines gradually move a signed exposure from 0 toward +1/-1 over three game years. The activity factor is exp(exposure * log(0.69) / 2); the full regular/inactive endpoint ratio equals the published RR. The log-midpoint is a game reference, not the measured national activity distribution. Routine classification and transition time are game assumptions.",
    "smoking": "No smoking is inferred from job, poverty or personality. Only explicit accepted smoking/cessation choices change exposure. Exposure builds or falls linearly over ten game years; factor = published current/never HR ^ exposure. This is a game interpolation inspired by long-term cohort evidence, not a measured yearly cessation curve. No smoking factor before age 20; retaining the adult factor after age 79 is an explicit game extrapolation.",
    "combination": "Multiplier is the geometric mean of the condition, activity and smoking factors, including neutral 1 channels. This equal-weight attenuation avoids multiplying three full overlapping associations. It is a game combination rule, not a published joint effect or validated personal risk model. No population-prevalence calibration is claimed.",
    "limitations": "Adult observational associations are transported to fictional historical and global lives as a simulation approximation. They do not establish effects for children, historical medical systems or every country; modifiers are disabled below age 18. AI may tag a qualitative effect with an exact choice-text quote; it never supplies coefficients, probabilities, health scores or death ages. Unsupported or unchosen effects are not applied. Birth-card life expectancy, child risk and result survival comparisons remain the unmodified sourced population reference, not a personalised prediction. Historical events do not add another mortality multiplier. No drinking, sleep, diet or named-disease mortality coefficient is invented."
