Every number should have a visible path.

1. Confirmed input: the spelling and calendar date selected by the user.
2. Deterministic calculation: versioned code produces values and traces.
3. Traditional interpretation: reviewed content associated with the method and value.
4. AI synthesis: a generated explanation combining approved facts and context.

The current Western profile repeats values 1 through 9 across A through Z. Life Path uses all date digits and preserves declared master numbers. Name tools preserve the raw compound total and reduce only the complete confirmed spelling. Additional variants will be separate method profiles rather than silent substitutions.

Reference used for the mapping and Expression method: Hans Decoz, Expression Number methodology.

The current Cheiro-derived profile maps Latin letters to values 1 through 8, preserves the compound total, and then reduces it. Nine is not assigned to letters in this table. Name normalization remains visible.

Tradition source: Cheiro's Book of Numbers. This records a practitioner tradition; it is not scientific validation or proof of an unchanged ancient Babylonian origin.

The raw birth-date grid counts digits 1 through 9 in the fixed 4-9-2 / 3-5-7 / 8-1-6 arrangement. Zero is omitted, derived Driver and Destiny numbers are not inserted, and all three rows, columns, and diagonals are checked. Missing cells are not described as defects.

Method comparison: Lo Shu history and raw-DOB calculation.

Mulank reduces the day of birth. Bhagyank reduces the complete date. The current profile uses modern number-to-planet correspondences and labels them as conventions rather than established ancient facts.

Personal Year uses the reduced birth month and day with the selected calendar year. Personal Month adds the calendar month; Personal Day adds the calendar day. This profile changes years on January 1 and reduces every timing result to 1–9, including 11 and 22.

Business candidates receive Pythagorean and Chaldean name values. Founder alignment compares Pythagorean business values with the founder's Expression and Life Path, and Chaldean business values with the founder's Chaldean name value. Exact matches are displayed directly; the product does not invent a compatibility or success percentage.

Current calculation engine version is 0.2.0. Artifacts identify their schema, engine, and method profile. The expanded golden fixtures have passed implementation review, but independent practitioner sign-off is still pending and will not be represented as complete until a named reviewer approves the declared variants.

Reproducible arithmetic does not validate personality or predictive claims. Nuemero presents numerology as a traditional interpretive framework and will publish an evidence-grading policy with its Research library.
