# Flatpak manifest — one build that runs on any Linux distribution.
#
# In plain terms: a Flatpak bundles the application together with the exact
# libraries it needs, so it does not care whether the user runs Ubuntu, Fedora
# or Arch. Unlike the buried egui-era manifest, this one does not
# build anything: CI has already built the Flutter bundle and packed the
# FFmpeg 8.1 libraries into its lib/ directory (the launcher's rpath covers
# them), so the manifest just repacks that staged bundle. The GNOME runtime
# supplies GTK 3, which the Flutter Linux embedder needs and the plain
# freedesktop runtime does not ship.
#
# CI (release.yml, linux-bundle job) copies the staged bundle to
# packaging/flatpak/bundle/ before running flatpak-builder; to build locally on
# Linux, do the same with a `flutter build linux --release` bundle, with the
# FFmpeg .so files copied into its lib/ and the share/ files staged as the job
# does. This .flatpak is the whole Linux release.

  # Where footage may be read from.
  #
  # In plain terms: a video editor reads footage from wherever the user keeps
  # it, and external drives are where most people keep it, so plain
  # --filesystem=home is not enough on its own. This used to be
  # --filesystem=host, which is everything the host has outside flatpak's own
  # deny-list — and that includes every *other* user's home directory, /opt,
  # /srv and any top-level directory at all. A compositor that parses untrusted
  # project files, imports arbitrary media and hosts third-party native plugins
  # is not a program that should be able to read another account's documents.
  #
  # So: this user's home, and the three places removable and mounted volumes
  # actually appear. That covers the case host was granted for without granting
  # the rest of the machine with it.
  #
  # A user whose footage lives somewhere else — a dedicated array at /data, say,
  # which is a normal thing for this kind of work — grants exactly that one
  # path, once:
  #
  #     flatpak override --user --filesystem=/data io.github.luminalmvm.Lumit
  #
  # That is a better arrangement than granting it to everybody by default, and
  # it is the answer Flathub reviewers ask for.
  #
  # The narrower still — no filesystem access at all, everything through the
  # document portal — is real work rather than a manifest change: the engine
  # stores absolute media paths and reopens them across sessions, so it would
  # need to hold portal document handles instead. Tracked, not pretended at.
