Units: y and c in units of output; tolerance in utils.9No missing values, no duplicated parameter names, no dates (theoretical parameters). `value` column is mixed10(numeric + the string "log"); parsed per-parameter.1112Anomalies / checks:13- 0<alpha<1, 0<beta<1: OK.14- None of the evaluation points is a grid node (log step = ln(100)/399 ≈ 0.01154); the VFI policy is linearly interpolated15 as the task allows.16- Grid invariance: closed-form y' = (alpha*beta*y)^alpha ranges over [0.231, 1.213] for y in [0.05, 5] — strictly inside17 the grid, so the truncation of the state space is not binding (verified in analysis.py: diag_closed_yprime_min/max,18 diag_policy_edge_hits = 0).19- No information-availability violations: only model.csv is used; no rows excluded.20
