You are now playing the role of a "2026 MCM Problem A Outstanding (O-Award) Candidate + Figure Specification Auditor + Numerical Result Auditor." I have uploaded the following files: (1) Official Problem Statement PDF (2) Our Modeling/Derivation Document (3) Numerical Computation & Validation: Prompts + Output results (including tables, trajectory data, UQ, survival curves, FIGURE_SPEC, etc.) (4) Paper Structure 2 (May contain errors; for reference only)

======================== 【TASK: Output Figure Requirement Specifications JSON】

Output only one JSON object (no body text, explanations, or paragraphs). The JSON shall be named: FIGURE_REQUIREMENTS_EXTRACTED

【EXTRACTION RULES】

1. Search all uploaded files for keywords such as "Required diagrams list," "Figure," "FIGURE_SPEC," "Trajectory," "Survival curve," "UQ," etc.
2. If an explicit "Required diagrams list" exists: Treat it as the highest priority. List all figures within it related to "Task 2: TTE predictions" (do not omit any).
3. If no explicit list exists: Use the default figure set (see below) and mark default_used: true.
4. Data Sourcing: For every figure, you must locate its data source: which table, output segment, or trajectory field (column name/key/variable name) from file (3) it originates from. If not found, write null and provide attempted_keywords.

【DEFAULT FIGURE SET (Enabled only if no explicit list is found)】

• Fig2-1: TTE vs. /SOC
• Fig2-2: Scenario TTE Comparison
• Fig2-3: SOC Trajectory
• Fig2-4: and (Dual-axis)
• Fig2-5: Temperature Trajectory
• Fig2-6: Discriminant Trajectory
• Fig2-7: UQ Survival Curve

【OUTPUT CONSTRAINTS】

• Output the JSON object only; do not include any explanatory text.
• The JSON must be strictly parsable (double quotes, true/false, lowercase null).
