Orbit Wallpaper Engine v0.1.2

[0.1.2] - 2026-08-26

v0.1.2 is the Polish & Release Hardening milestone. It does not provide true
live apply; ordinary configuration changes still restart the renderer.

Added

• Frontend-neutral orbit-wallpaper-control API with structured status,
  correlated animation commands, configuration staging, restart, and shader
  operations.
• Safe shader installation and application with licence/capability checks,
  blacklist enforcement, rollback, and previous/next installed-shader cycling.
• Wayland compatibility probing with compatible, unsupported, and cannot-verify
  outcomes, including permanent incompatibility status 78 handling.
• Bounded Hyprland login and lock/unlock reference transitions.
• Minimal optional Noctalia integration consisting of the palette hook and an
  icon-only launcher for the canonical Settings application.

Improved

• Canonical Settings UI now uses the control API, has a scrollable content area,
  clearer action hierarchy, reachable narrow-window controls, and preserved
  shader-browser selection and scroll position across refresh/apply.
• Restart-required Apply now exits the current wallpaper, restarts with the
  staged configuration, waits for readiness, and replays the intro animation.
• Apply failure restores the previous configuration and attempts renderer
  recovery instead of silently leaving the desktop without a working state.
• Service reload now uses the bounded control API and animation timeouts follow
  configured intro/exit durations.
• Steam/Hyprland integration reconnects across compositor instance changes and
  treats unavailable sessions as recoverable.
• Installation modes now distinguish canonical GUI, optional integrations, and
  headless/core-only installation while retaining compatibility aliases.

Fixed

• Boolean startup settings no longer treat the literal value 0 as enabled.
• Renderer readiness is not reported until all active outputs have valid EGL
  surfaces.
• Output removal, layer closure, hotplug slot reuse, monitor geometry changes,
  and mode changes no longer necessarily terminate or strand the entire
  renderer; affected surfaces are retired and recreated.
• Settings Apply no longer clears dirty state before successful process exit or
  starts the follow-up operation after a failed staging response.
• Settings staging no longer mutates the canonical configuration before Apply;
  successful Apply persists the candidate atomically before restart.
• Hyprland/Noctalia lock requests now use the active Hypridle boundary with
  bounded wallpaper exit and unlock intro handling.
• Narrow action rows wrap without clipping, and the standalone Settings window
  now opens at a 900x760 default size for the current content.
• Shader-browser filtering no longer leaves an invisible selection active, and
  browser delegates remain inside their list margins.
• Uninstall removes the optional Noctalia plugin instead of leaving stale files.

Deferred

• True runtime/live parameter apply is reserved for v0.2.0.
• Audio/audio-reactive shaders and additional shader inputs are reserved for
  v0.3.0.
• GNOME/Mutter backend support remains future investigation with no promised
  implementation date.
