This is a heuristic order-of-magnitude argument, not a derived bound, and it ignores the extra error from linearly interpolating a step-function policy.",16 "suggested_fix": "Call it an approximate scale (about half the investment step times the savings share) rather than a bound, and mention the interpolation component."17 },18 {19 "id": "R3",20 "severity": "minor",21 "location": "out/report.md (Limitations) / claims.json C3",22 "issue": "C3's '<0.5% relative' holds only narrowly (0.484% at y=2).

The code reads only data/model.csv, uses the prescribed 400-point log grid, the 1e-8 tolerance and the given parameters. The VFI (discrete choice over y' on the grid, starting from V0=0) never uses the closed form. The guess-and-verify derivation, the closed-form numbers (c=(1-αβ)y, savings rate 0.342, V(1)=-19.5244), the contraction modulus β=0.95, the iteration-error bound 1.9e-7, and the relative errors (-0.06%, +0.15%, -0.48%) all check out. The policy never hits a grid bound. Required report sections, assumptions and the scope of the validation are present, and the limitations are honest. Only minor wording issues remain."27}28
