Subject: [PATCH 01/13] feat(nodes): extract Slint overlay into standalone
 video::slint node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new video source node (video::slint) that renders .slint UI
components to RGBA8 frames via the software renderer.  The node has no
inputs and a single broadcast output, following the same lifecycle as
colorbars (Ready → Start → Running).

Key design decisions:

- All Slint operations run on a single shared std::thread (lazily
  slint::platform::set_platform() is process-global.
- Each node gets a unique NodeId (UUID) and communicates with the shared
  thread through tagged work items and per-node result channels.
- A thread-local RefCell<Option<Rc<dyn WindowAdapter>>> is swapped
  before each definition.create() / component.show() call so every
  ComponentInstance is associated with its own MinimalSoftwareWindow.
- The new 'slint' feature does NOT depend on 'compositor', keeping the
  two fully decoupled.
- Properties can be set at init and updated at runtime via UpdateParams.
- Property keyframes cycle at a configurable interval.
- frame_count == 0 gives infinite real-time output; frame_count > 0
  produces exactly N frames then stops.

Sample pipelines updated to use standalone slint nodes wired as
compositor inputs instead of embedding slint_overlays in compositor
config.

+//! Standalone Slint UI video source node.
+//!
+//! Compiles a `.slint` file at init time via `slint-interpreter` and renders
+//! RGBA8 frames using the software renderer at a configurable resolution and
+//! frame rate.  The node has no inputs — it is a video source, just like
+//! `video::colorbars`.  Its output can be wired into the compositor (or any
+//! other node that accepts raw video) as a regular layer.
+//!
+//! ## Threading
+//!
+//! `slint::platform::set_platform` is process-global, and the types it
+//! manages (`MinimalSoftwareWindow`, `ComponentInstance`) are `!Send`
+//! (`Rc`-based).  To support multiple `SlintNode` instances in one process
+//! without UB, **all** Slint operations are funnelled through a single
+//! dedicated `std::thread` (lazily spawned via `OnceLock`).  Each node
+//! communicates with this shared thread through tagged work items and
+//! per-node result channels.

Subject: [PATCH 02/13] fix(nodes/slint): use tokio::sync::mpsc for result
 channel and add serde default to slint_file

- Switch result channel from std::sync::mpsc to tokio::sync::mpsc so the
  async run() method uses .recv().await instead of blocking the tokio
  worker thread.  The Slint thread side uses blocking_send().
- Add #[serde(default)] to SlintConfig.slint_file so partial UpdateParams
  JSON (e.g. only properties) deserializes correctly instead of silently
  failing.

Subject: [PATCH 04/13] fix(nodes/slint): merge only runtime fields in
 UpdateParams instead of replacing whole config

Partial UpdateParams JSON (e.g. {"properties": {"score": 5}}) would
silently fail because the deserialized SlintConfig had an empty slint_file
which failed validate().  Now UpdateParams merges only the runtime-changeable
fields (properties, property_keyframes, keyframe_interval) into the existing
config, preserving immutable init-time fields.

Subject: [PATCH 05/13] fix(nodes/slint): merge properties via extend instead
 of replacing in UpdateParams

Partial UpdateParams JSON (e.g. {"properties": {"home_score": 4}})
was replacing the entire properties map, dropping unmentioned keys.
Now uses extend() to merge only the provided keys.

property_keyframes and keyframe_interval are treated as init-time config
and left unchanged by merge_update, since serde defaults make it
impossible to distinguish absent fields from user-provided empty values.

Subject: [PATCH 06/13] feat(samples): replace oneshot scoreboard with static
 watermark overlay

The scoreboard's Slint Timer is wall-clock-based and doesn't advance
meaningfully in batch mode (frame_count > 0) where frames render faster
than real-time.  Replace the oneshot demo with a static watermark badge
that works correctly in both batch and real-time modes.

The scoreboard remains available in the dynamic pipeline
(video_moq_slint_scoreboard.yml) where frame_count: 0 ensures real-time
pacing and timers work as expected.

Subject: [PATCH 07/13] fix(nodes/slint): call request_redraw() before
 draw_if_needed()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without an explicit request_redraw(), MinimalSoftwareWindow's
draw_if_needed() only invokes the render closure when the window is
marked dirty.  For static UIs (no property changes, no active timers)
the window stops being dirty after the initial show(), causing
draw_if_needed() to skip rendering and leave the pixel buffer zeroed
(fully transparent).  This made overlays like the watermark invisible.

Calling request_redraw() before every draw_if_needed() guarantees a
full repaint each frame.  With RepaintBufferType::NewBuffer there is
no wasted incremental-diff cost — the renderer always paints the
entire scene anyway.

Subject: [PATCH 08/13] perf(nodes/slint): cache rendered frame buffer between
 unchanged frames

Static UIs and frames between keyframe boundaries now reuse the
previously rendered RGBA8 buffer instead of re-rendering through the
Slint software renderer and premultiplied-to-straight conversion on
every frame.

Re-rendering is triggered only when:
- The node is first registered (dirty = true)
- An UpdateConfig work item arrives (runtime property change)
- The keyframe index crosses a boundary

The frame counter still advances on cached frames so keyframe
boundaries are detected at the correct time.

Subject: [PATCH 09/13] fix(samples/slint): fix watermark compilation error and
 cache rendered frames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove invalid 'vertical-alignment' property from Rectangle in
  watermark.slint — this caused Slint compilation to fail silently,
  producing no frames at all (the actual root cause of the invisible
  watermark).

- Cache rendered RGBA8 buffer on the shared Slint thread.  Static UIs
  and frames between keyframe boundaries now reuse the previously
  rendered buffer instead of re-rendering on every frame.  Re-rendering
  triggers only on: first frame, UpdateConfig, or keyframe boundary.
  The frame counter still advances on cached frames so keyframe
  boundaries are detected at the correct time.

Subject: [PATCH 11/13] fix(samples/slint): polish watermark layout and
 alignment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Wrap accent dot in a VerticalLayout with alignment:center so it is
  vertically centred within the badge row (previously top-aligned).
- Shrink badge to 180×44 px for a tighter, cleaner look.
- Slightly increase border-radius and padding for better proportions.
- Use semi-bold LIVE tagline with higher-contrast white-70% colour.
- Update pipeline YAML to match new badge dimensions (x=1080).

Subject: [PATCH 12/13] =?UTF-8?q?fix(nodes/slint):=20address=20review=20fe?=
 =?UTF-8?q?edback=20=E2=80=94=20caching,=20blocking,=20platform=20errors?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Critical fixes:
- Always call update_timers_and_animations() unconditionally in the
  Render handler so Slint Timer/animation state advances even when
  frames are served from cache.
- Add static_ui config flag (default false) to opt into frame caching
  for truly static UIs; dynamic UIs always re-render every frame.
- Replace blocking_send with try_send on the result channel to avoid
  head-of-line blocking on the shared Slint thread when one node's
  consumer is slow.

Suggestions:
- Propagate set_platform() error instead of silently discarding it.
- Clear CURRENT_WINDOW thread-local after component.show() to prevent
  stale Rc references.
- Replace spin_on (busy-wait) with pollster::block_on for .slint
  compilation; yields to the OS instead of burning CPU.
- Document merge_update limitation in dynamic pipeline YAML comments.

Nits:
- Add #[serde(default)] at struct level on SlintConfig (matches
  ColorBarsConfig pattern).
- Simplify registration to use SlintConfig::default().
- Change SAFETY comment to Invariant: (SAFETY is for unsafe blocks).

Watermark pipeline updated with static_ui: true.
