  1. expH runs #2-#3: first falsified hypothesis + first quantized capture
    …
    Run #2 (cold cache, M3U96a, purge/repeat): FALSIFIED — warm ordering
inverts; zarr-uncompressed 0.62 GB/s beats raw-mmap 0.14 on cold random
batches (page-fault QD1 IO vs 32MiB chunk reads). Rule: IO granularity
decides, not the container. Store design revised; run #4 registered.

Run #3 (mlx-lm Qwen3-0.6B-4bit): CONFIRMED — retain 1.004x plain prefill
(capture free under lazy eval), retain+write 1.28x. First quantized-model
activation capture in Python tooling.
