The maths
Sample chart math
Every House Call reading sits on top of one of these computed sheets. This is an anonymised real chart - the date and place have been redacted, but the positions, pillars, and dasha periods are exactly what the practitioner sees before they start writing.

Pillars derived from the lunisolar calendar; Day Master from the day pillar's heavenly stem.
| Pillar | Heavenly stem | Earthly branch |
| Year | Xin (Yin Metal) | Si (Snake) |
| Month | Gui (Yin Water) | Si (Snake) |
| Day | Yi (Yin Wood) | Hai (Pig) |
| Hour | Gui (Yin Water) | Wei (Goat) |
Day Master: Yi Wood (Yin Wood)
Five-element balance: Water-supported Wood with Fire output; modest Metal influence

What the practice does with this
The Western, BaZi, and Vedic sheets above are fed to a custom LLM trained on the matching reference corpora — one corpus per tradition, sourced from three anonymous tradition consultants. The model drafts each tradition’s section against its own framework, then a synthesis pass that identifies where the three converge (high-confidence claims) and where they diverge (honest uncertainty). The practitioner — the editor — reads every draft against this sheet line by line, cuts claims the chart doesn’t support, rewrites the synthesis where the traditions strain against each other, and ships.
Without this sheet, every paragraph in the reading is just opinion. With it, every claim has a citation - which planet, which pillar, which dasha period, made which prediction. That's the difference between House Call and a horoscope.
