# Natal Chart Compute one static natal chart, write `natal_<name>.json` and `natal_<name>.md`, then hand the verified JSON to `natal-reading` automatically. The artifacts hold placement data only; never interpret the chart here. ## Route before calculating - Two people being compared belong to `synastry`. - An existing natal artifact that needs meaning belongs to `natal-reading` without recalculating. - Four pillars or twelve palaces belong to the `chinese-metaphysics` plugin. - Transits, progressions, solar and lunar returns, dated events, and forecasts are outside this release; state that rather than improvising them. ## Require one resolved birth record A natal chart needs an exact time. Houses, the four angles, and the sect all move with it, and a chart missing them is not a shorter natal chart — it is a different artifact. Collect without guessing: - `name`: display identity for the artifact, and nothing else. - `birth.date`: exact `YYYY-MM-DD`. - `birth.time`: exact `HH:MM` in 24-hour form, with `time_mode` set to `exact` and `time_accuracy_minutes` set to `0`. - `birth.timezone`: historical IANA zone such as `Asia/Shanghai`. - `birth.latitude` and `birth.longitude`: decimal degrees for the birthplace. Resolve a place through an available geocoder or map source. If several places match, stop for a location choice; do not silently take the largest. If the person only knows the hour, or only the date, say plainly that this skill cannot place houses or angles from
