+## Synthetic Trajectory Ensemble
+
+Run:
+
+```bash
+python scripts/trajectory_ensemble.py --architectures 16,16 24,24 32,32 48,48 24,24,24 --samples 256 --steps 200 --lr 0.02 --eval-every 20 --feedback-runs 40 --data-seed 20 --init-seed 30 --feedback-seed-start 1000 --plot
+```
+
+This runs one BP baseline and many FA feedback seeds for each architecture,
+then aggregates:
+
+- final FA/BP loss gap;
+- full and hidden-only gradient cosine;
+- initial and final \(Q_l\) means;
+- initial and final log-volume capacity cost;
+- within-architecture and pooled correlations.
+
+Outputs are written under `outputs/trajectory_ensemble/`:
+
+- `run_summary.csv`
+- `architecture_summary.csv`
+- `correlations.csv`
+- `trajectories.csv`
+- diagnostic plots when `--plot` is set.
