+# scripts/legacy
+
+One-shot scripts kept for historical reference. They were tied to specific
+experiments (cluster paths, deleted output dirs, removed CLI flags such as
+`--time-scale` / `--max-inflight-sessions`) and are no longer expected to
+run as-is.
+
+For new experiments use `scripts/bench.sh`. Pre-existing structured
+analyses still live in `scripts/` (e.g. `analyze_trace.py`,
+`analyze_breakdown.py`, `analyze_cache_hit.py`, `analyze_eviction.py`,
+`compare_results.py`, `compute_roofline.py`).
+
+If you need to revive a legacy script, expect to:
+
+- update hardcoded paths (cluster `/home/admin/cpfs/...`, deleted trace
+  files, missing `outputs/<exp>/...` directories);
+- adapt to the current replayer CLI (`--time-scale` and
+  `--max-inflight-sessions` were removed when methodology moved to
+  trace-driven dispatch);
+- re-verify the assumptions documented in `REPORT.md`.
