Automatic updates leave no other trace. The Flatpak that sat here as "1 update
available" installed itself at 00:14 this morning and nothing on the machine
would have said so.
Both sources are asked in their own machine-readable form and merged on time, so
the answer reads as one history rather than two lists to interleave by eye.
Two parsing traps worth recording next to the code. flatpak's --json prints
timestamps as "Aug 20 08:07:46" with no year in them, so the year is inferred
and a date that would land in the future is read as last year's. And dnf5's
start_time is epoch UTC while its own history table prints that same value as
though it were local -- checked against rpm, and the local rendering here is the
correct one.
The contract asserts entries are newest first, that none is dated in the future,
and that both sources parse; it was verified to fail by breaking the year
inference so every flatpak entry landed tomorrow.
Loaded on demand rather than with the page, because it reads both full
transaction logs.
