FST paper yields a limited two-axis frontier

GTKWave manual Appendix F Table V reports five FST variants on one 5 GB VCD. On size versus conversion time, plain zlib (30.58 MB, 100.85 s) is dominated by LZ4 plus gzip-4 (18.91 MB, 77.71 s). LZ4 without deduplication (88.21 MB, 75.76 s) remains formally nondominated because it is 0.44 s faster than regular LZ4, but no uncertainty is reported to establish that tiny difference. These historical single-thread conversion figures cannot establish a frontier including live dump overhead, cold-open latency or selective reads; gzip wrapping also changes the access path.
