KAF visual asset provenance

This repository is an unofficial, non-commercial fan project. Nine local images in this directory are tied to individual piapro work pages whose current license conditions were checked again on 2026-08-25. The separately documented 狂想β album cover is sourced from the official KAF discography page and is included only for non-commercial fan-site identification under the KAMITSUBAKI secondary-creation guidelines. Public availability alone is not treated as permission to copy unrelated assets.

License references:

Piapro states that its work-specific icons control use: the non-commercial icon limits use to non-commercial purposes, the creator-name icon requires attribution, and the no-modification icon prohibits modification. The FAQ states that a work without the no-modification condition may be modified, subject to the platform's restrictions. None of the nine piapro image work pages below displayed an original-license condition at the 2026-08-25 check.

The original local files use piapro's published display thumbnails and remain unchanged as provenance inputs. The public work pages report larger source dimensions, but original downloads require a piapro account; this repository does not bypass that access boundary or substitute unverified reposts.

Responsive display derivatives

On 2026-08-30, the nine verified piapro preview inputs were converted into responsive display derivatives under src/assets/kaf/generated/. The delivery ladder was re-encoded on 2026-09-03 to reduce first-visit transfer:

  • tool: official waifu2x-ncnn-vulkan portable macOS release 20250915;
  • model: models-cunet;
  • processing: 4× scale with noise level -1 (no denoise), preserving the verified preview as closely as the selected model permits;
  • outputs: longest-edge 480/960/1280/1920/2560 WebP candidates downsampled from the verified 4× master;
  • WebP quality: 78 for thumbnails and 82 for larger candidates;
  • reproducibility: scripts/generate_kaf_media_variants.py verifies every source SHA-256 before generation;
  • derivative dimensions, byte sizes, and SHA-256 values: src/assets/kaf/generated/manifest.json.

The official 1600×1600 狂想β cover is not AI-upscaled. Its responsive files are source-native technical derivatives only: 480/960/1200/1440/1600 WebP candidates and a 32px inline placeholder. No creative alteration is applied.

These derivatives improve display density and reduce browser enlargement. They do not restore the inaccessible original pixels and must not be represented as source originals. The source preview files listed below remain the authoritative local provenance inputs.

Usage boundary

  • Keep the site explicitly unofficial and non-commercial while these images ship.
  • Keep required creator names visible in the page-bottom source line and retain the per-work source/license entries in the adjacent 图片来源 disclosure.
  • Re-check the exact work page before materially changing distribution context or creating a new derivative.
  • Remove the corresponding local file and content reference if its source terms become incompatible.
  • The 狂想β entry is a narrow reviewed exception requested for this non-commercial album listing. Do not treat it as blanket permission for other KAF/KAMITSUBAKI official images, campaign materials, album covers, social-media reposts, logos, screenshots, or wallpapers.

avatar/kaf-fukuro-hatdown VRM model

  • Website usage: public rendering and download through the site's versioned Pages Function URL
  • Distribution architecture: the 49,911,472-byte VRM is stored in Cloudflare R2 and is not committed to Git or the Pages static artifact
  • Public model URL: https://kafu-8bd.pages.dev/assets/models/kaf/v1/kaf-fukuro-hatdown-5fe890c94a7af1e5.vrm

  • Model format: VRM 0.x / binary glTF
  • Embedded usage metadata: creator mme; commercial use disallowed; redistribution prohibited by the embedded default metadata. The creator's direct website-specific permission is the basis for this deployment and does not grant downstream users an additional license

Static poster derivative

  • Local path: avatar/poster/kaf-fukuro-hatdown.webp
  • Source: the VRM's embedded metadata thumbnail kaf_chara_zhaimao.png
  • Generation: python3 scripts/kaf-avatar/extract_vrm_poster.py
  • Processing: deterministic upper-body crop and Lanczos resize to 960×1200 WebP, quality 86
  • Byte size: 88,532
  • SHA-256: 3af7e7efaffb36242f219dec4dd83f7460244307941861661294b8eef2dca580
  • Purpose: model-loading, reduced-motion, WebGL-unavailable, and error fallback

The public download exists so visitors and repository users can reproduce the model version rendered by the site. It must not be described as an MIT-licensed or otherwise open-licensed model merely because the transport URL is public. The model creator's permission and KAMITSUBAKI's secondary-creation boundary continue to apply independently from this repository's source-code license.
