+pkgdesc='Dead-simple, Markdown-only presentation app built with Qt Quick'
+# Only x86_64 has ever been built and tested. aarch64 is plausible (the build
+# is plain qmake6 + make) but unproven, so it is not claimed here.
+arch=('x86_64')

+# No .install file. On current Arch, gtk-update-icon-cache.hook and
+# update-desktop-database.hook already refresh both caches, and namcap flags a
+# scriptlet that duplicates them. Spec §15 milestone 8 wanted the agent skill
+# installed from a scriptlet; it cannot be — that runs as root and the skill
+# belongs in the invoking user's home — so Omapresent links it itself on first
+# run (Backend::installAgentSkill) from the copy packaged below.
+# The binary carries no useful debug symbols for a release package, and the
+# split -debug package trips namcap's empty-package rule.
+options=('!debug')
+# Spec §12's list needed three corrections, each checked against the built
+# binary rather than assumed:
+#   * qt6-quickcontrols2 is not a package on Arch. Quick Controls 2 and Quick
+#     Dialogs 2 ship inside qt6-declarative.
+#   * qt6-multimedia is a runtime module. `QT += multimedia` in omapresent.pro
+#     links libQt6Multimedia even though no QML file imports QtMultimedia, so it
+#     is a runtime dependency as well as a build dependency.
+#   * gst-plugins-{base,good,bad,ugly} are not in the playback path at all.
+#     Local video is an HTML <video> element (src/renderer/render.js:335)
+#     decoded by QtWebEngine's own Chromium stack, which Arch links against
+#     ffmpeg and openh264 through qt6-webengine. GStreamer is never loaded.
+# No yt-dlp, per the spec.
