    "The civil year contains portions of two native years. BaZi changes at physical Li Chun; Ziwei retains the canonical lunar-year and late-Zi rulebook in the report timezone.",
    "Annual themes use native annual/decade context and Jupiter-through-Pluto transits. Solar months, Ziwei months and Mars contacts refine timing; they are not whole-year conclusions.",
    "Western windows use configured orbs with six-hour discovery and one-minute refinement. Separate retrograde passes and multiple local closest contacts are retained; a clipped closest contact need not be exact.",
    "Solar returns, progressions, standalone eclipses/lunations, stations/ingresses and transiting Sun/Moon/Mercury/Venus are not calculated in this annual version.",
    "Symbol-to-domain mappings and monthly selections are bounded editorial policies, not exhaustive absence claims, causal evidence, probabilities or independent predictive validation."
