Vendored third-party packages (under third_party/):

  * ComfyUI-WanVideoWrapper
      Author:   Kijai
      Source:   https://github.com/kijai/ComfyUI-WanVideoWrapper
      License:  Apache-2.0
      Usage:    Optional Kijai-backend integration for the Wan Director
                (nodes/wan_director/director_node.py, when backend="kijai").

  * WhatDreamsCost-ComfyUI (LTX Director — behavioural inspiration only)
      Source:   https://github.com/WhatDreamsCost/ComfyUI
      License:  GPL-3.0 (verified May 2026 — see upstream LICENSE).
      Usage:    Our `js/wan_director_timeline.js` is a CLEAN-ROOM
                reimplementation. No source code from the upstream file
                `js/ltx_director.js` was copied, ported, or transformed
                into our file. Only the *timeline_data JSON schema* and
                publicly observable interaction behaviour were used as a
                reference so a user's saved LTX-Director timeline can be
                round-tripped through ours. The file is original work
                authored under Apache-2.0. If you believe any portion is
                substantially similar to GPL-3 source, please open an
                issue and we will reauthor the affected section.

  * ComfyUI_LayerStyle (layer effects port)
      Author:   chflame163
      Source:   https://github.com/chflame163/ComfyUI_LayerStyle
      License:  MIT (declared in the upstream pyproject.toml and README;
                the clone under third_party/ ships no LICENSE file).
      Usage:    nodes/layer_effects/ is a PORT, not a clean-room rewrite.
                The eight MEC/LayerEffects nodes carry the feature union of
                upstream's V1/V2/V3 variants of drop_shadow, inner_shadow,
                outer_glow, inner_glow, stroke, color_overlay,
                gradient_overlay and gradient_map.

                Reimplemented in torch rather than copied verbatim, for a
                concrete reason: upstream's py/blendmodes.py imports the
                `blend_modes` pip package, which is not installed in this
                ComfyUI, so a straight copy would fail at import. The blend
                table is checked against a numpy transcription of the
                upstream formulas in tests/test_layer_effects.py.

                Four defects in the upstream are fixed here and each has a
                test: an UnboundLocalError at zero offset, a size-mismatched
                mask being replaced with solid white, a python list returned
                through an IMAGE socket, and RGBA returned on an IMAGE socket.
                The sign of distance_x/distance_y is deliberately inverted
                relative to upstream so that positive moves the shadow right.

                The front-end (js/c2c_layer_effects.js) is original work: the
                upstream ships none for these nodes.

                Second batch, nodes/mask_toolkit/: the LayerMask family. Only
                the five capabilities this pack did not already have were
                ported - Mask From Color, Mask Gradient, Mask Grain, Mask
                Motion Blur and Edge Spread - plus a channel selector and
                Blend-If soft ends folded into the EXISTING LuminanceKeyerMEC
                rather than added as a sixth node. The rest of LayerMask was
                deliberately not ported: MaskEdgeUltraDetail V1/V2/V3,
                MaskGrow, MaskEdgeShrink, MaskInvert and MaskPreview are
                covered by MaskRefineMEC, MaskStroke by LayerEffectStrokeMEC,
                MaskBoxDetect/Extend by nodes/bbox_nodes.py, and the eight
                Segformer nodes and RemBgUltra need model weights.
                Front-ends in js/c2c_mask_toolkit.js and the shared
                js/_c2c_fx_controls.js are original work.

  * Virtuoso Pack (blend-mode table, via ComfyUI_LayerStyle)
      Author:   Chris Freilich
      Source:   https://github.com/chrisfreilich/virtuoso-nodes
      Usage:    ComfyUI_LayerStyle's py/imagefunc.py:2506 credits this pack
                for its 30-mode blend table, which nodes/layer_effects/
                _blend.py reimplements in torch. Credited here because the
                credit is owed upstream of our own upstream.

  * ComfyUI-KJNodes
      Author:   Kijai
      Source:   https://github.com/kijai/ComfyUI-KJNodes
      License:  Apache-2.0 (subject to upstream LICENSE in vendored copy).
      Usage:    Vendored copy under third_party/ComfyUI-KJNodes (see its
                own LICENSE/NOTICE files).

  * Prompt Relay (refined port)
      Author:   Gordon Chen & contributors
      Source:   https://github.com/GordonChen19/Prompt-Relay
                https://gordonchen19.github.io/Prompt-Relay/
      License:  Upstream has no explicit LICENSE file (May 2026); author has
                publicly stated the project is open / free for use. This port
                is distributed under the Apache-2.0 license of this repository
                and will be relicensed if upstream attaches a conflicting one.
      Usage:    Refined re-implementation in nodes/prompt_relay/, with added
                Kijai-WanVideoWrapper and generic-model backends. See
                nodes/prompt_relay/NOTICE.md and
                THIRD_PARTY_LICENSES/PromptRelay-NOTICE.txt.
