Ziwei marketing often jumps straight to “what your career palace means.” Daovian starts one layer earlier: which stars sit in which palaces for your birth data, under a named construction fork.
Facts vs verdicts
| Layer | Example | In product |
|---|---|---|
| Engine fact | Life palace major stars include 破军 | Shown on the chart |
| Algorithm rule | Chart built with iztro bySolar, fixLeap true |
Visible in calculation rules |
| AI narration | Restates those stars and retrieved passages | Optional; cannot invent new placement |
If a sentence cannot point to a fact panel or a rule/passage, it should not ship as a strong claim.
How to verify
- Enter the same civil date, time (Beijing wall clock), and sex twice.
- Confirm the twelve palace names and major-star lists match.
- Open How we calculate for the documented iztro fork and time-index mapping.
- Treat the result as life reference — not absolute fate.
