It is consistent with the numbers but is a thin basis for a general statement.","suggested_fix":"Word it as 'non-monotone across the 200/400/800 grids examined', or add more grid sizes."},5{"id":"R3","severity":"minor","location":"out/report.md (Uncertainty, discretisation heuristic)","issue":"The error heuristic (1/alpha)*k*(dlny/2) is an order-of-magnitude bound (about 0.011 at y=2, against an observed 0.0064). The report uses it to 'explain' the observed errors without saying it is only a bound.","suggested_fix":"Describe it explicitly as an approximate upper bound."}6],7"summary":"I re-ran analysis.py in a scratch copy and it reproduces results.json exactly; the run is deterministic and reads only data/model.csv. The closed form c=(1-alpha*beta)y and V=A+B ln y check out: an independent numerical maximisation of the Bellman right-hand side at y=0.5, 1, 2 matches the closed form to about 1e-7. The numerical policy comes from discrete VFI argmax on the prescribed 400-node log grid and is never built from the closed form. The tolerance is respected, no grid bound binds, all required keys are present, the error magnitudes are internally consistent, and the required closed-form assumptions, contraction argument and validation scope are all stated. I found only minor traceability and wording issues."}8
