Schema: parameter (str), value (numeric except grid_spacing='log'), description (str). No missing values, no duplicate
parameter names. Values: alpha=0.36, beta=0.95 (both in (0,1)), y_min=0.05 < y_max=5.0 (units of output),
grid_points=400, grid_spacing=log, vfi_tolerance=1e-8 (utils, sup norm), eval_y = 0.5, 1.0, 2.0.
No dates (theoretical parameters). Anomalies: none. Note: the evaluation points are not nodes of the 400-point
log grid (log step 0.01154), so the VFI policy must be interpolated there (permitted by TASK.md).
Interior check: steady state y* = (alpha*beta)^(alpha/(1-alpha)) ~ 0.547; optimal y' at y=0.05 is ~0.23 and at
y=5 is ~1.21, both strictly inside [0.05, 5], so grid bounds do not bind (confirmed in script: 0 choices at bounds).
No input violates the information-availability rules. gate_spec.json/bundle.json are not task inputs; not used.
