The Day Master is the reference; polarity selects one label in each pair.
Start from five element relationships
Take the Day Master as the reference. Another stem can share its element, produce the Day Master’s element, be produced by it, control it, or be controlled by it. Those five relationships are then split by whether the other stem has the same or opposite yin-yang polarity. Five times two produces the ten named classes.
This means a stem does not carry one permanent Ten Gods label. A Jia stem viewed from a Jia Day Master has a different relation than Jia viewed from a Ding Day Master. A calculator should derive the label from stem metadata, not store a context-free label on the character.
The ten labels form five pairs
Same-element relationships form Friend and Rob Wealth. Elements that produce the Day Master form Direct Resource and Indirect Resource. Elements produced by the Day Master form Eating God and Hurting Officer. Elements controlled by the Day Master form Direct Wealth and Indirect Wealth. Elements controlling the Day Master form Direct Officer and Seven Killings.
Polarity selects the member of each pair according to the documented rule table. English names are translations and can sound moral or literal when they are actually technical categories. Treat ‘wealth’, ‘officer’, or ‘killings’ as established labels inside the system, not factual predictions about money, status, or harm.
Visible stems and Hidden Stems use the same derivation
The other three visible pillar stems can each be related to the Day Master. Every Hidden Stem inside an Earthly Branch can be classified through the same function. MingWeave preserves each Hidden Stem’s main, secondary, or residual order from its rule table, then shows the corresponding Ten Gods label for the chart’s Day Master.
A label’s position, visibility, season, root, and surrounding interactions are separate information. Counting labels alone loses that structure. P0 therefore presents the underlying stem, element, polarity, and relationship rather than reducing the chart to a score or a single recommended action.
Use the relationship matrix to audit a result
Find the Day Master, identify the other stem’s element relation, compare polarity, and then read the expected pair. If a label looks wrong, this four-step path makes the issue testable. Golden tests in the deterministic engine cover every Day Master against every stem so a UI label cannot silently replace the rule.
Interpretation comes after derivation. You can use the labels as prompts for examining support, expression, exchange, or constraint, while keeping claims proportionate. MingWeave avoids advice that treats a symbolic category as evidence for health, legal, career, or financial decisions.
