Task 265: 3D Analysis Epoch Data Sync in Cross-Episode Report

Status: DONE

Motivation

Task 264 updated the epoch (2241→2214) and re-ran 3D orbital analysis (3d_orbital_analysis.json).

However, the cross-episode report (cross-episode.md) 3D section still contains pre-epoch-change values:

1. Saturn ring crossing approach angle: Report says ~27°, JSON says 9.33°
2. Uranus approach angles: Report says ~60°/70°, JSON says 25.3°/14.3°
3. Z-height bar chart: Old values (e.g., Mars 6839, Jupiter 17373) vs JSON (Mars 4047, Jupiter -6416)
4. 3D parameter table 面外距離: Old values (10,534/391/31,928/13,998) vs JSON (10,462/54,052/11,262/36,529)
5. Prose text: References to ~27° and ~60° approach angles are stale

Scope

• Update all numerical values in cross-episode.md 3D section to match 3d_orbital_analysis.json
• Update side-view diagram angles
• Update bar chart values
• Update table values
• Update prose descriptions
• Add article content validation tests to prevent future divergence
• Re-run npm run analyze-3d if values seem questionable

Dependencies

• Task 264 (epoch resolution) — DONE
