What changed

On Fedora, a lock skin picked in the Hub does not stay on the sign-in screen. sddm-theme-ryoku owned the skin files in /usr/share/sddm/themes/ryoku, the directory the picker writes to, so each package update put Orbital back. The Hub kept naming the pick. The Arch packaging has no owner for this path, so only Fedora is affected.

 sddm-theme-ryoku
-  owns themes/ryoku/{Main.qml,metadata.desktop,theme.conf,...}  # flat Orbital
+  owns themes/ryoku/ only

 ryoku-desktop %posttrans
+  if themes/ryoku/Main.qml is missing
+    re-host themes/ryoku/theme if it holds a skin, else seed Orbital

Area

ryoku

How it was tested

Real rpm -U upgrades of sddm-theme-ryoku, built from the old and new specs, in a throwaway RPM root. The new %posttrans block was extracted from the parsed ryoku-desktop spec and run against that root:

Scenario	Root Main.qml	theme/
Before: pick a skin, update the old package	Orbital (overwritten)	the pick, ignored
After: pick a skin, upgrade to the new package	host	the pick
After: update the new package again	host	the pick
After: never picked, upgrade	host	Orbital
After: already overwritten, no theme/	host, stale files cleared	Orbital, until the skin is re-applied

• The bug was seen on a Fedora 44 box: ~/.config/qylock/theme said last-of-us while the greeter's Main.qml matched the shipped Orbital byte for byte, and an earlier pick's bg.mp4 was still beside it.
• SELinux is not the cause. The loaded policy allows xdm_t to read the data_home_t labels that cp -a carries over.

Not tested:

• Building the full ryoku-desktop RPM. Its spec was parsed, and the scriptlet passes sh -n.
• Booting into the fixed greeter after a real package update.

Merge danger

Door: two-way. Reverting restores the old package payload. The only skin data involved is the copy under /usr/share; the user's copy under ~/.local/share is never written.

Blast radius: Fedora login screen.

• A box whose skin was already overwritten comes back on Orbital while the Hub still names the pick, and has to re-apply it once. The Hub ignores a click on the active skin, so that means picking another skin and switching back, or running ryoku-hub lock set <slug>.
• The one-time upgrade erases the old package's files and rebuilds with a 12-hour clock until doctor next corrects it.
• If the %posttrans block fails, the greeter directory has no Main.qml until a skin apply. The failure is logged under ryoku-greeter. Doctor treats a missing Main.qml as "not installed", so it will not repair this.

Checklist

• One logical change, with a clear [area] scope: summary commit subject.
• Matching CHANGELOG.md updated in the area I touched.
• The git hooks pass locally; I did not use --no-verify.
• Lua parses (luac -p), shell scripts pass bash -n, and QML passes
  qmllint where applicable. (No Lua or QML changed; the scriptlet passes sh -n.)
• No duplicated config, no dead code, no commented-out code, no em-dash.
• Docs updated if behavior or layout changed. (No docs describe this package's payload.)
