+# FishingBuddy project identity
+
+## Canonical maintained fork
+
+The canonical repository designated by the current maintainer is:
+
+- https://github.com/Dusk-92/FishingBuddy
+
+Mirrors, package caches, downstream forks, repackaged copies, and modified
+versions hosted elsewhere are independent unless this canonical project
+explicitly states otherwise.
+
+## Independent community project
+
+This repository is an independent community-maintained fork of historical
+Fishing Buddy code.
+
+It is not affiliated with, sponsored by, approved by, or endorsed by Blizzard
+Entertainment, Sutorix, CurseForge, OctoWoW, aim2kill, refaim, or any other
+referenced project or maintainer unless explicitly stated by that party.
+
+Compatibility with World of Warcraft 1.12-compatible clients, OctoWoW, Titan,
+FuBar, Gatherer, Outfitter, myAddOns, InfoBar, ButtonHole, or other optional
+addons does not imply affiliation, endorsement, partnership, or ownership.
+
+World of Warcraft, Warcraft, Blizzard Entertainment, and associated names,
+marks, artwork, and game assets remain the property of their respective rights
+holders.
+
+## Known GitHub fork chain
+
+The current GitHub ancestry is:
+
+- https://github.com/aim2kill/FishingBuddy
+- https://github.com/refaim/FishingBuddy
+- https://github.com/Dusk-92/FishingBuddy
+
+The historical addon itself predates these GitHub repositories and is credited
+to the Fishing Buddy author identity Sutorix in the addon metadata and
+documentation.
+
+## Official upstream status
+
+The current official Fishing Buddy and Fishing Buddy (Classic) CurseForge
+projects are maintained by Sutorix and are marked "All Rights Reserved".
+
+This repository does not claim that the existence of older GitHub forks creates
+a permissive license for the inherited addon.
+
+## Support boundary
+
+Dusk-92 is responsible only for changes and releases published by the canonical
+maintained fork. Historical authors, upstream maintainers, optional dependency
+authors, Blizzard Entertainment, CurseForge, and OctoWoW are not responsible
+for this fork's modifications or current behavior.
