The update surface was a panel the user had to reason about: Check again,
Rollback client, Stage launcher, Install client, Cancel, Close, plus an
installed/available version table, a minimum-launcher-version sentence, and a
"restart required" banner they had to act on. Reaching it meant knowing to
press "Check for updates" in the header.
Now: the feed is checked once at startup. If nothing is out of date, nothing
appears. If something is, one dialog says what is new and offers Update or
Not now.
Launcher before client, deliberately. A client release can declare a minimum
launcher version, so updating the launcher first is what makes the client
update installable at all — and it means nobody is ever shown "install
launcher X or newer before the client update", which is not a sentence a
player should have to read.
A launcher update now restarts into the new build by itself. That reuses the
existing, proven handoff rather than inventing a second one: LauncherSelfUpdate
Bootstrap.TryApplyStagedUpdateNowAsync starts the staged payload in helper mode
against the CURRENT process, exactly as ordinary startup does, and the launcher
then shuts down. Restarting by spawning a fresh copy of the current launcher and
letting its startup notice the staged plan would look simpler and be wrong: the
helper would wait on the new copy while the old one still held its own
executable mapped, so the file replacement could fail. The staged-helper launch
is extracted into one private method both paths call, so they cannot drift.
Deleted: the header "Check for updates" button, OpenCommand, CheckCommand,
InstallClientCommand, StageLauncherCommand, RollbackCommand, CloseCommand, the
version table, IsLauncherMinimumBlocked/MinimumLauncherStatus, the restart
banner, and LauncherUpdatePhase plumbing through the view model.
NOT deleted — none of the safety changed: manifest validation, bounded verified
download, safe ZIP extraction, versioned install with an atomic current.json
switch, the update session barrier, and rollback all still live in
AcDream.Launcher.Core/Updates. Rollback simply has no button; it remains
reachable as Core API with its own tests. The complexity the user objected to
was the panel, not the machinery underneath it.
An unreachable feed stays silent. A friend with no internet must still reach
their characters, so a failed startup check shows nothing at all rather than an
error to dismiss.
Tests: LauncherUpdateViewModelTests rewritten against the new surface (8 tests
— nothing-to-do stays silent, client update installs, launcher update stages
then restarts without touching the client, no-restart-seam fallback, silent
offline, Not now, refused while a session runs, failed install reports why).
Tests for the deleted commands are removed with them, not skipped.
Launcher 59 passed, Launcher.Core 335 passed.
Campaign LU slices LU2 and LU3, landed together because the new prompt replaces
the old one in the same files.
