  README claimed but nothing measured.
 - `footprint_bench` reports whether it built `float16` or `f32` stores and
  takes `--f32`; it had kept printing "f32" after the default changed.
+- New `concurrent_read` harness, with an h5py counterpart
+  (`crates/clawhdf5-bench/scripts/concurrent_read_h5py.py`, threads or
+  processes) and `compare_concurrent_read.py`: decoded read throughput and
+  scaling efficiency at 1-16 threads on one open file, full reads of distinct
+  datasets and random hyperslabs of one dataset, deflate and contiguous, warm
+  or `--cold` page cache, JSON output. Not yet measured — `BENCHMARKS.md`
+  ("Concurrent reads") has the commands and no numbers.

 ### Interop
 - **h5py could not open chunked datasets we wrote with a chunk dimension
