Overview
Heavenly Stem Hidden Lu is the standard English name for 天元暗祿. The classical rule takes only four complete day pillars: Geng-Yin, Yi-Si, Bing-Shen and Ji-Hai. “Hidden Lu” does not mean a generic missing Lu star. Each day uses the branch beneath the Day Master to hold or generate a specific Officer route, and each route has different desired Wealth, Resource or control evidence and different blockers. OpenFate can calculate the pillars, hidden stems and Ten Gods, but it does not output Heavenly Stem Hidden Lu as a pattern.

Heavenly Stem Hidden Lu is an exact four-day allowlist
The source names Geng-Yin, Yi-Si, Bing-Shen and Ji-Hai. Matching only the Day Stem, only the Day Branch or a Lu star elsewhere does not reproduce this rule. The complete day pillar is the entry condition.
The term “hidden” refers to a relationship carried within the seated branch rather than an excuse to invent an absent symbol. Hidden stems, their Ten God roles and their actual support must remain visible in the explanation.
Match one of four complete Day Pillars.
Never write an inferred Officer or Lu back into the natal pillars.
The four days need four separate validation routes
Geng-Yin looks to Ding Officer in the Fire growth contained by Yin and checks Earth support plus control of exposed Bing Killing. Yi-Si looks to Geng Officer and Wu Wealth within Si, favoring their usable exposure and Resource while distinguishing Xin Killing and excessive fire.
Bing-Shen reviews Geng-Xin Wealth, Gui Officer and Jia-Yi Resource while guarding against Wu-Ji Output damage. Ji-Hai uses Jia Officer growing in Hai and checks whether Metal harms that Officer route. These branches cannot be replaced with a universal hidden-Lu formula.
Route first by the exact Day Pillar.
Evaluate useful and harmful Ten Gods within that route.
OpenFate can expose every input without claiming the pattern
The engine calculates the complete Day Pillar, hidden stems, Ten Gods, month command, strength and relevant interactions. These are enough to audit each of the four historical routes.
It has no Heavenly Stem Hidden Lu detector and does not transform a hidden stem into a guaranteed Officer or Lu outcome. This page leaves reports, scores and saved calculations unchanged.
Use engine facts as evidence, not as an implicit verdict.
A future detector must have four distinct rule paths.
Hidden Lu does not promise office, income or lifespan
Classical examples use official rank, wealth and lifespan as proof of a pattern. Those biographical claims do not create a reliable prediction for a modern reader.
Heavenly Stem Hidden Lu cannot guarantee employment, promotion, authority, money, health or longevity. Use real qualifications, finances and professional guidance for consequential choices.
