| - Indirect association ({construct_names[0]} → {construct_names[1]} → {construct_names[2]}): {path_summary['indirect']}; 95% bootstrap CI [{path_summary['indirect_ci'][0]}, {path_summary['indirect_ci'][1]}]. | |

| [STRICT EMPIRICAL INSTRUCTION] | |
| 1. ZERO HALLUCINATION: Every study-specific fact and number must come from this frozen packet. Never invent a country, named organization, sampling frame, response rate, demographic characteristic, measure source, software package, coefficient, p-value, fit index, robustness test, or date. | |
| 2. DESIGN DISCIPLINE: This is a cross-sectional observational survey. Use association language. The indirect estimate is not causal mediation identification. | |
| 3. MEASUREMENT DEFENSE: State reliability/convergent/discriminant validity only when the displayed values support it. | |
| 4. RESULTS DISCIPLINE: Results must report this study's frozen numbers without attaching external citations to the coefficients or sample facts. | |
| 5. ROBUSTNESS: The Spearman matrix, bootstrap intervals, and VIF above are the only frozen robustness evidence. Do not add another robustness procedure. | |
| 6. CONSISTENCY: The predictor, mediator, outcome, sample size, context, scale, and all numerical results above are the single source of quantitative truth throughout the manuscript. | |
