    ## IMPORTANT: Code-Only Mode

    In this task you are in **code-only mode**. You must:
    1. Read and analyze the paper
    2. Write `reproduction/ANALYSIS.md` with your methodology analysis
    3. Implement ALL code files under `reproduction/`
    4. **DO NOT** run the scripts or generate CSV data files
    5. Focus on writing correct, complete, and well-structured code

    Your deliverables are ONLY the analysis document and code files.
    Do NOT produce any CSV data files.

          Read every code file carefully. Check whether the implementation is
          physically and algorithmically correct:
          - Tunneling rate: ADK formula (EQ-9) with importance sampling
          - Tunnel exit: parabolic coordinate equation (EQ-11-13)
          - Propagation: adaptive RK4 for Newton's equations (EQ-14)
          - Phase: SCTS formula with 2Z/r Coulomb term (EQ-22)
          - Coulomb mapping: asymptotic momentum (EQ-26-29)
          - Post-pulse phase: Coulomb correction (EQ-40)
          - Observable: coherent sum (EQ-41)
          - SFA parallel velocity (EQ-47-48)
