fn full_round_after(sharing: &Sharing<'_>, memory: &mut Memory) -> u64Expand description
What this computer appends since its last full round before it opens the
next: as much as that round restated, and a megabyte at least
(ROUND_SIZE). A phone’s full round restates its whole archive of texts
(16 MB on the owner’s phone, 14 October 2026); opened at each megabyte
appended, as until 15 October 2026, the full rounds cost the folder and
the connection many times what was appended (eDrive sends each twice).
Now restating never costs more than what was appended since, and the
rounds a device joining reads stay within twice the last full round. Its
size, not known to a memory from before, is read once from that round’s file.
