## Title-page notice

Title: Krita Color Smudge changes what brush spacing means. Editorial additions: AI-assisted Fodev JEO editorial article, 2026. Publisher: Fodev JEO. Original document: Color Smudge Brush Engine, Krita Manual. Original principal authors credited by the source: Wolthera van Hövell tot Westerflier; Raghavendra Kamath; Scott Petrovic; ValerieVK; Peter Schatz. These authors did not author or endorse the new analysis.

Copyright in original material remains with the Krita Manual contributors. Copyright (c) 2026 Jang Young Jeong, original editorial additions. The original footer states: “Copyright licensed under the GNU Free Documentation License 1.3+ unless stated otherwise.” The source page license field states “GNU free documentation license 1.3 or later.” No specific copyright year for the four illustrations is asserted.

**Article-specific permission:** Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A complete unaltered copy is included in [GFDL-1.3.txt](GFDL-1.3.txt). No invariant sections, cover texts, acknowledgements, dedications, or additional warranty disclaimers were designated in the inspected source document. The license's own warranty language is preserved in full.

## Image scope and modifications

The [pinned official contribution guide](https://invent.kde.org/documentation/docs-krita-org/-/raw/87d1c035f7db9696eae7badfe9ac38a7eb6bf984/contributors_manual/krita_manual_readme.rst) explicitly applies the manual's license to submitted images. Its spelling “GDPL” is retained in evidence, not treated as a different license: the repository LICENSE and document identify GFDL. None of these four source placements carries a different CC license caption. This is documentation-asset licensing, not a software GPL or MIT inference.

All four originals are preserved unchanged in the separately retained offline review package. Three publication copies are byte-identical. For brushengine_smudge_radius.png, the publication derivative removes only the tEXt keyword Software with value www.inkscape.org. No copyright, author, licensing, color, or image data was removed. The remaining complete chunks including CRCs are byte-identical. Full hashes and verification remain in the separately retained offline provenance-v3.json review package; it is not a public article asset.

The cover is an original AI-generated conceptual paint illustration made using god-tibo-imagen with the existing Codex backend. It is not Krita output, a screenshot, a benchmark, or an upstream illustration. No manual images were used as generation references. A centered crop from 1672×941 to 1664×936 yields the 16:9 publication PNG without upscaling. It remains outside references/ and is not one of the four credited source images. No separate human-authored copyright claim is made for the AI-generated pixels; the cover is included in this licensed document package to the extent rights are held.

- Modified document: Krita Color Smudge changes what brush spacing means, 2026; AI-assisted editorial additions published by Fodev JEO. Changes: new mode-first decision analysis, original comparison table, unexecuted test proposal, selected source illustrations, attribution, this history, and a separately identified conceptual cover. One source image receives the metadata-only change described above. No Krita runtime trial was performed.

The [complete original RST source](color-smudge-engine-source.rst) is included without alteration, preserving its authorship and license metadata. Its upstream image paths are source references, not promises that every image from the original manual has been bundled. The four included images have their own pinned original URLs in article captions.

The transparent modified article is available as [public Markdown source](https://raw.githubusercontent.com/akillness/akillness.github.io/master/_posts/2026-10-07-krita-color-smudge-spacing-modes.md). The article links to all five included images, the full license, this notice and the preserved original source.
