Tandem 4.73

• Coherence pass, part 3 (the enrichment): the program library learns which
  of its programs have an update waiting. flatpak and snap each know, per
  app, whether a newer version is out - but asking costs a network round
  trip, and the library is the main screen, opened all the time. So the
  answer is CACHED: the check runs at most once a day, in the background,
  stamped before the attempt (the self-update check's shape), and writes the
  updatable ids to a file; the screen reads only that file, so it opens
  instantly and never blocks on the network. t_biblioteca carries the answer
  as a sixth field, tem_update (sim/nao) - only an updatable source can hold
  one, and only if the cache lists it, so it never invents an update. The
  field is a pure read (the refresh is triggered separately by the command
  path), so it stays safe to call from a test. On-disk cache values are
  English and lowercase like the memory tokens, never translated.
• This is the invisible-but-testable engine; the visible green/amber dot and
  the Update button on each row come next, reading exactly this. Pinned with
  stubbed flatpak/snap: an app the check found reports an update, one the
  cache does not list reports none, an updatable app with nothing waiting is
  marked nao and one with an update is marked sim, and the daily throttle
  fires once then the day's stamp skips it. No new message, no behaviour
  change on the apt path or anywhere a program opens.

Install

sudo apt install ./tandem_4.73_all.deb

Then, to install whatever is missing (Wine, winetricks, Android):

tandem preparar

Not on Debian or Ubuntu? Fedora, Arch, openSUSE and the rest
have no apt to take a .deb. Use the generic bundle instead:

tar xzf tandem_4.73_generic.tar.gz && cd tandem-4.73
sudo ./install.sh          # sudo ./uninstall.sh removes it

On Arch? A PKGBUILD is attached (with tandem.install):
makepkg -si from a directory holding both, or install tandem
with your AUR helper once it is published there.
