The Instrument Shop

Four instruments.
One shared core.

認 知 機 能 研 究 所

Every number on this site is cast by the same engine. The compass and the calendar will never disagree with each other — that is the whole point of building the tools instead of borrowing them.

0 · The Entrance
The Binary Check
M B T I ・ 二 択

Twenty-four yes/no questions, about two minutes, confidence 0.55 — printed on the page rather than hidden. It produces four letters and hands them straight to the compass. A tied axis is reported as held, not guessed.

I · The Whole Chart
Metaphysical Compass
メタフィジカル・コンパス

Eight concentric rings — western zodiac, 干支, personal year, destiny, soul urge, birth day, life path — with the Jungian function stack burning at the centre. The single view that shows how the frameworks agree.

II · Timing
Cycles
個 人 の 周 期

Your Personal Year and Personal Month on the birthday-to-birthday clock, plus the full twelve-month arc. Numerology's most usable output: not who you are, but when the door opens.

III · The Sky
Natal Chart
西 洋 占 星 術

Real ephemeris math — ten bodies, the ascendant, the midheaven, whole-sign houses and the major aspects. Each figure carries its own confidence limit, stated rather than hidden.

IV · The Month
The Calendar
普 遍 日 の 頻 度

Universal Day frequency across a month. Which combinations repeat, which fire only once, how dense the master days are, and what backdrop the 28th happens to wear.

On the shared core These four instruments load the same reduction engine. Type Labs holds that a chart reducing to 2 is reading a collapsed Master 11, and that rule is applied identically everywhere — so a Life Path cast on the compass will match the one the calendar assumes. Where a figure is an approximation rather than a computation, the instrument says so on its own page.
