+**Post-push verification of this fill, measured rather than promised.** The fill
+landed as `00df4e6`, and after that push the same anonymous raw path was re-read:

+to disk**, and its sha256 `4a17e8ee17a65dce20898ae16e562a8aea22490ef31c40c3e8d8467c2bb6479e`

+(103,128 B) — so the served bytes, the disk bytes and the committed bytes agree on
+all three sides at the revision that now exists, and the pre-append row above is

+files are untouched by this fill and their rows above stand.
