Pullarr is a modified derivative of Kapowarr, originally authored by Cas van Tijn and Kapowarr contributors (https://github.com/Casvt/Kapowarr). Application license: GNU GPL version 3; see LICENSE and retained source notices. Pullarr modifications include provider-neutral identity, reviewed organization, acquisition, quality/provenance, discovery, archive maintenance and publication hardening (2026). This is not an official upstream release. The public history is a source snapshot, not a claim of sole authorship. Upstream copyrights and license terms survive the history boundary. CLU / Clu Comics was a GPL-compatible implementation reference; existing file-level notices remain. Original Pullarr SVG branding and the geometric UI replacement icons are covered by the application license. Third-party utilities and libraries are identified separately in THIRD_PARTY_NOTICES.md and their supplied licenses.
