Tandem 4.81

• Native RPM packaging for the rpm families - Fedora (COPR) and openSUSE
  (OBS) - the equivalent of the Arch/AUR recipe (4.62) for the other side of
  the packaging world. packaging/rpm/tandem.spec installs from the same
  distribution-agnostic generic tarball as the .deb and the AUR package,
  running its install.sh with DESTDIR, so what it packages cannot drift from
  the .deb; its %files list is generated from the tarball's MANIFEST so the
  list cannot rot as files are added or removed. %post/%postun refresh the
  shared caches and show the install notice READ from the catalogue in the
  machine's language, never sourced, exactly as the .deb postinst and the
  pacman scriptlet do. build.py --check guards the spec's Version against
  debian/control (the spec is committed, because COPR builds it straight
  from the repository), and a new suite section asserts the spec's shape and
  proves that guard fires on a version mismatch. The .xapk/.apks/.apkm
  handler's unzip dependency is declared and guarded. Built and installed
  end to end on a real Fedora 41, where tandem doctor reads "package
  family: dnf". packaging/rpm/README.md documents publishing on COPR and OBS.

Tandem 4.80

• The program library gains a per-program Remove action - the one thing the
  main screen was missing: every row showed Open but no way to uninstall.
  Each of the six worlds a program can come from uninstalls its own way - a
  Flatpak per-user, a snap as root, a Waydroid app through Android, an
  AppImage by removing its menu entry, a Windows program through Wine's own
  uninstaller - and Tandem asks before removing anything and confirms it
  actually went, never a silent failure. A system program (one that came
  with the distribution) is not one-click-removed from here: Tandem says so
  and points at the system's software manager, because apt-removing a system
  package from a shop counter by a stray click is worse than not automating
  it. The decision of how each source uninstalls is a pure function with a
  proof-by-injection test; the click travels back through the same temp-file
  token contract the Open and Update buttons use.

Tandem 4.79

• A guard for the one thing the tools menu could still drift on: which tools
  each face offers. The two faces share their dispatch (acao_painel_executa),
  so what a tool DOES can never diverge - but the modern face reads the
  shared acao_painel_itens while the zenity fallback keeps its own two-level
  row list, so the SET of tools each face offers was kept in step only by
  hand. A new test asserts the modern menu (acao_painel_itens) and the zenity
  menu (acao_painel_zenity's rows, minus its "more"/"back" controls) offer
  the same set of tokens; adding a tool to one face and not the other now
  fails the suite instead of silently leaving the zenity user without it.
  Found by Codex reviewing the 4.78 record, which had overstated the
  guarantee as "both faces read one shared list" when only the dispatch is
  shared.

Tandem 4.78

• The Tools menu wears the One UI face now, the last shared surface still
  drawn as a plain 1990s list. The library main screen, the health panel,
  the wizard, the history, the error, the question and the progress bar all
  moved to the modern GTK4 look across the redesign; the "Tools" button on
  the library still opened a zenity list of doctor, backup, ports and the
  rest - the one screen a coherent product should not have left behind. It
  is a rounded-card One UI window now, one tap per tool, grouped into
  sections (Programs, Diagnosis, Your data, Community and help) instead of
  the two-level "more"/"back" list zenity forced because only eight rows
  fit its window. Every tool the old menu offered is still there, and no
  word changed in any of the seven languages.
• Safe by construction, the same way every other modern window is: gui.py
  grew a "menu" mode that draws the cards, and acao_painel_moderno falls back
  to the zenity two-level list, then to the help text, on any machine
  without libadwaita, without a display, or with TANDEM_GUI=zenity. Both
  faces dispatch through one shared acao_painel_executa, so the modern look
  and the fallback can never drift on what a tool does. A drawing failure
  becomes exit 2, never a traceback.

Tandem 4.77

• The last Portuguese word on the library screen is gone. Each program's row
  shows where it came from - Wine, AppImage, Flatpak, snap, Waydroid - and
  those are proper nouns that stay as they are in any language; but a program
  from the system's own catalogue read "sistema", a plain Portuguese word,
  to a shop owner running the machine in English or another language. It is
  shown translated now - System, Sistema, Systeme and so on - while the
  record on disk keeps the token "sistema" - the same split the memory screen
  uses, on-disk value untouched, only the shown label mapped. The decision is
  a pure function (_display_fonte in gui.py: only "sistema" is mapped, every
  other source is returned as-is), pinned both ways, and t_bib_sistema still
  records the untranslated token. One new message (fonte_sistema), translated
  in all seven languages; rendered under real GTK4.

Tandem 4.76

• An "Update all" button on the program library, the way a phone's app store
  has one. It sits above the install action and appears ONLY when at least
  one program actually has an update waiting (t_bib_ha_updates); one press
  updates them all behind the progress window - flatpak updates its own apps,
  and snap goes through t_como_root because it needs a password. It touches
  ONLY the managers the cache says have an update (t_bib_atualiza_tudo), so it
  never asks for a root password to refresh snaps when only a flatpak needs
  updating. When it is done it refreshes the update cache and reopens the
  library, so the amber dots turn green in front of the owner; and a failed
  update is NOT silent - it says so with a plain sentence, the project's
  first rule. The decision of which manager to run is pure and pinned with
  stubs that log every call (flatpak alone does not trigger snap, a snap
  update goes through root), and the button's visibility is gated on a real
  update in every direction. Three new messages (bib_atualizar_tudo,
  atualizando_tudo, atualizacao_falhou), translated in all seven languages.
  Rendered under real GTK4 - an amber button matching the update dots.

Tandem 4.75

• The program library gets a view control, the way a file manager does. A
  small "organize" selector sits to the right of the system filters, with
  three modes: by name (A-Z, the default), by system (grouped, with a header
  per system - Windows / Android / Linux, the grouping a file manager shows),
  and by update (what needs acting on first: an update waiting, then not
  checked, then up to date, then the programs Tandem does not manage). The
  order is a PURE function (_order_items in gui.py), imported headless and
  pinned in every direction - by-name sorts across every system, by-system
  groups under a header per system with apps by name within, by-update ranks
  amber first, and an unknown mode falls back to by-name. The list is rebuilt
  on search, chip and sort together, so a grouped view can insert its headers.
  Rendered under real GTK4 in the grouped and by-update views. Three new
  messages (ordem_nome, ordem_sistema, ordem_update), translated in all seven
  languages. Deliberately NOT a "by size" or "by date" sort: those are not
  uniformly available across the six program sources (only flatpak exposes an
  installed size; most expose no install date), and a sort that is blank for
  half the list would be worse than none - the no-false-data rule.
• A test-isolation fix rides along, found by the suite hanging on this
  machine: the boff_run helper (added in 4.74) exercises t_biblioteca but
  stubbed only flatpak, so t_bib_snap ran the real snap list, which hangs on
  snapd on a machine that has snap installed (intermittent - it passed CI and
  an earlier local run, where snap errors fast). It stubs snap now, the way
  bib_run and bup_run already do; a helper that drives the library must
  isolate every tool the library calls.

Tandem 4.74

• Coherence pass, part 3 (the visible enrichment): the program library now
  SHOWS which of its programs have an update. 4.73 built the engine (a daily,
  cached, network-free check writing a sixth field, tem_update); this draws
  it. Each program's icon carries a small status dot pinned to its corner,
  FOUR states: amber = an update is waiting, green = checked and up to date,
  a hollow ring = updatable but not checked yet, gray = Tandem does not manage
  this program's updates (a Windows or Android program, an AppImage, a distro
  package). A row with an update also gains an amber "Update available" note
  beside its source, so the fact is not hidden in a tooltip nobody hovers; the
  dot itself carries a tooltip naming its meaning in the machine's language.
• A green "up to date" is only ever shown behind a REAL check - the project's
  own rule that a check it could not run reports unknown, never healthy (the
  health command's lesson). The update worker marks a source "checked" only
  when that source's own command exits 0, so on a first launch or offline the
  source is not marked and its apps read the hollow "not checked yet" dot
  instead of a green the machine cannot back up. The gray tooltip was reworded
  from "updates with the system" (which misdescribed Wine/AppImage/Android) to
  "Tandem doesn't manage its updates".
• The dot's state is a PURE function (_update_dot in gui.py), imported
  headless and pinned in every direction - amber only when an update waits,
  green only when checked and current, the hollow ring when updatable but
  unproven, gray for anything Tandem does not update. It reuses the palette
  the health panel already uses, so it reads as one product. Safe by
  construction, like every gui.py window: the dot falls back to the bare icon
  on any error, never a traceback, and the whole screen still falls back to
  the old menu with no GTK4. Rendered under real GTK4 in all four states. Four
  new messages (dot_atualizar, dot_atual, dot_gerido, dot_checando),
  translated in all seven languages. The one-click Update button that acts on
  an amber row comes next (v4.75).

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.

Tandem 4.72

• Coherence pass, part 3: the main screen IS the library now. The old zenity
  menu of commands - the one screen a shop owner who never opens a terminal
  saw, and the one the owner said he detested - is replaced by a One UI window
  that shows every installed program: the system's own mark on each row (the
  Windows window, the Android robot, the Linux Tux penguin - drawn fresh, no
  trademark art copied), a search, per-system filter chips, an Open button per
  program, and a bar to install a new file. It reads the 4.71 enumeration
  engine (t_biblioteca), so it needs no new source of truth.
• A click comes back through a temp file, the exact contract the health
  panel already uses: "abrirfontelancador", "instalar", or
  "ferramentas". The shell reads it and does the rest; gui.py never launches
  or installs anything itself. t_bib_lancador decides how each program opens
  (gio launch for a .desktop, flatpak run, snap run, waydroid app launch) -
  pure, so the decision is pinned by a test - and t_bib_abrir runs it
  detached with the target as ONE quoted argument, never concatenated into a
  command.
• Nothing is lost. A "Ferramentas" button opens the old menu, so doctor,
  backup, ports and the rest are one tap away; and with no GTK4 the whole
  screen falls back to that menu, which itself falls back to the help text -
  the fallback the error/question/text/progress windows all share.
• The system names on the chips (Windows/Android/Linux) live in gui.py, a
  descriptive category label that is the same in every language; only the
  labels that translate (All, Open, Install, Search, Tools, the count) go
  through the catalogue - 6 new messages, translated in all seven languages.
• Rendered under Xvfb and checked against the approved mockup: the window,
  the three system marks through librsvg, the chips, the search. gui.py home
  with no display refuses fast (never hangs behind an invisible window).
