Movement Has Cause

“Cause” here means a chart-reading path: an observed factor changes a recorded state or relation under a named rule. It does not mean that a branch symbol physically causes an outside-world event.

Cause/relevance audit

For every moving line, Dark Moving flag, transformed relation, clash, combination, or San He record, complete one row:

Observed factor	Rule and authority	Path to target	Effect on existing record	Decision
				keep / background / drop / unresolved

A factor is retained only when all four explanatory columns are complete.

Same-position transformation boundary

The “Moving-Line Generation, Control, Clash, and Combination” chapter of Zengshan Buyi states that a transformed line acts back on its own moving line, not on other primary lines. That provides a bounded path:

transformed row at position n → its moving row at position n → target relation, if that moving row is relevant

Do not jump directly from a transformed branch to an unrelated line.

Weather chapter case, line 2

Example type: documented mechanics; no source outcome.

• observed factor: line 2 moves from Yin Wood to Mao Wood;
• received label: Zengshan Buyi, “Advance and Retreat Spirits,” chapter 36 lists 寅化卯 (Yin→Mao) as an advance transformation on printed p. 55;
• same-position path: transformed line 2 acts on primary line 2;
• target connection: primary line 2 is the selected target;
• course comparison step: no category change follows from the advance label alone;
• permitted conclusion: retain the classified same-position transformation, while marking any effect on the target’s comparison tier unresolved unless a separate cited rule completely states that change.

Do not compare the course record with the source’s reported weather observation as validation.

Irrelevant-movement counterexample

Example type: invented exercise.

A moving line has a clear self-transformation but no relation to target, support, obstacle, support-blocker, World/Response path, or retained frame. Its correct decision is background or drop.

Movement is not relevant merely because it is visually prominent.

Final judgment record

After dropping unsupported factors, write:

provisional direction or abstention → target/obstacle mechanism → retained active factors → evidence-quality tier → unresolved limit

If removing an irrelevant factor changes the direction, return to the outcome-rule page and recompute rather than defending the earlier wording.

Trap and stopping condition

• Do not use “movement has cause” as metaphysical or physical causation.
• Do not retain every moving line to make the reading sound complete.
• Do not let a transformed row act on unrelated primary rows without a separate located rule.
• Stop when any direction-changing factor lacks an explicit target path.

Same-position scope: Zengshan Buyi, “Moving-Line Generation, Control, Clash, and Combination” (动变生克冲合章), chapter 15, checked composite printed p. 26. Advance/retreat classification: Zengshan Buyi, “Advance and Retreat Spirits” (进神退神章), chapter 36, checked composite printed pp. 55–57; 寅化卯 appears on p. 55. The Yin→Mao pairing appears in Zengshan Buyi, volume 2, “Weather” (天时章第三十五), checked composite printed p. 90/PDF physical p. 91 and Chinese Text Project work ctp:ws157683, displayed paragraphs 996–1003. The broader keep/background/drop audit is an explicit UAYA teaching convention.

Act 7 is complete. Continue to Act 8: Timing and keep candidate timing separate from the judgment record.
