2978 files. The fork is 2026-07-15 (rebrand: gitea.dev -> github.com/hanzoai/git), so 2026 is the year, and "Copyright 2026 Hanzo AI, Inc." was already the form used by the handful of files that had ours. Shape is now: // Copyright 2026 Hanzo AI, Inc. All rights reserved. // Copyright 2015 The Gogs Authors. All rights reserved. // Copyright 2019 The Gitea Authors. All rights reserved. // SPDX-License-Identifier: MIT Ours on top, theirs retained verbatim. Retained because MIT requires it, and separately because they are true — those authors did write that code. Not renamed to "The Git Authors": Git is a different project under a different license, and putting its name here would attribute this code to people who have nothing to do with it. Adding our line is the fix; overwriting theirs would have been both a licence violation and a false statement. gofmt still reports import-order drift in some of these files. It predates this change (verified against a stash) and is left alone rather than burying a one-line-per-file legal change under 3000 files of unrelated reordering. Build clean.
