+### Changed
+- **Repository moved to the `kerrshift` organization**: canonical URLs now
+  point to `github.com/kerrshift/agentdiff` — package metadata
+  (`pyproject.toml` Homepage/Repository), README badge + clone link, the
+  baseline-envelope schema `$id`, and the docs link in `agentdiff init`
+  generated workflows. Reusable-action references are now
+  `kerrshift/agentdiff/.github/actions/agentdiff-check`; old
+  `lostmartian/agentdiff` URLs continue to work via GitHub redirects.
