When I re-ran the VFI, the absolute error does tend to rise with y (largest near y=4.72, corr(|e|,y)\u22480.79), but not monotonically. The relative error is roughly constant (about 0.39%) on most of the grid.",9   "suggested_fix": "Store a small error profile (e.g. error at a few grid quantiles) or the argmax location in results.json, or reword C5 to say only that discretisation, not iteration, dominates."10  },11  {12   "id": "R2",13   "severity": "minor",14   "location": "out/report.md Data and exclusions / Method",15   "issue": "The report points to files in out/state/ (SHA-256 manifest match, brute-force check at about 1e-13). These are not required deliverables and analysis.py does not regenerate them, so results.json cannot verify them.",16   "suggested_fix": "Either move these checks into analysis.py as diag keys or label them clearly as auxiliary and unverified by the pipeline."17  }18 ],19 "summary": "I re-ran analysis.py on a scratch copy and it reproduced results.json exactly. Every required key is present. The closed form c=(1-\u03b1\u03b2)y and V=A+B ln y is derived correctly by guess-and-verify, and the assumptions are stated. The VFI is a genuine discrete-choice iteration on the prescribed 400-point log grid with tolerance 1e-8, and it never uses the closed form. Off-grid evaluation points are handled by log-linear interpolation and recorded in data_issues. The optimal choice never hits the grid bounds. The contraction modulus \u03b2=0.95 is justified through Blackwell's conditions, with an honest caveat about unbounded log utility. The claims match the numbers: max policy error 0.0064 (about 0.5%), V(1) gap 3.4e-4, iteration error bound 1.9e-7. The scope limits are stated. The only issues are minor and concern how claims are documented."20}
