description	子平真诠派用神变化判断。Use when 月令取格 has produced an initial pattern but revealed stems, hidden stems, combinations, transformations, or meetings may change the useful-god direction, create a compatible secondary pattern, or damage the original pattern.

When to Use

Use after yueling-quge when:

• 月令 gives an initial pattern.
• Hidden stems, revealed stems, 三合/三会/六合, or transformations suggest the initial pattern may change.
• You need to distinguish 主格, 兼格, 变之而善, 变之不善, or 变而不失本格.

Inputs

{
  "initial_pattern": "",
  "month_branch": "",
  "hidden_stems": {},
  "revealed_stems": [],
  "branch_meetings_combinations": [],
  "ten_gods": {}
}

Procedure

1. Start from the initial 月令 pattern.
2. Check whether non-primary hidden stems are revealed.
3. Check whether branch meetings/combinations change the dominant structure.
4. Classify the change as beneficial, harmful, compatible, or uncertain.
5. Preserve uncertainty when main/secondary pattern evidence is close.
6. Pass the result to 成败救应 and 纯杂判断.

Output

{
  "initial_pattern": "",
  "change_candidates": [],
  "change_type": "变之而善|变之不善|变而不失本格|待定",
  "primary_pattern": "",
  "secondary_patterns": [],
  "evidence": [],
  "plain_explanation": ""
}

Boundaries

• Do not replace 月令取格; this skill only evaluates changes after initial entry.
• Do not force one final pattern if evidence is mixed.
• Do not decide 格局高低; call geju-gaodi.
