 - Start with synthetic full-batch regression and no-bias MLPs.
 - Record same-point gradient alignment by computing BP and FA gradients at the FA weights.
 - Treat early trajectory runs as instrumentation checks before drawing distributional conclusions.
+- Use within-architecture correlations as the first trajectory validation target; pooled correlations can be misleading because architecture-level task difficulty and BP final loss vary.
