Rename: plugin renamed from “Watrix User Switching” to “Watrix Login as User”; slug / text domain changed from watrix-user-switching to watrix-login-as-user to avoid confusion with the existing User Switching plugin.
uninstall.php: prefixed local variables ($watrix_lau_option_name, $watrix_lau_site_ids, $watrix_lau_site_id).
i18n: moved /* translators: */ comments to be immediately adjacent to the __() call.
nonce warnings: annotated the admin_init and admin-notice dispatchers (read-only status checks; the actual state-changing actions still verify nonces).
Packaging: added .distignore so .git, .gitignore, README.md and .DS_Store are excluded from the distribution ZIP.
1.0.1
i18n: switched UI strings to English source + translation catalogues. Japanese locale displays “切り替え” / “%s に切り替え”; other locales show “Switch to” / “Switch to %s”.
Security (H-1): removed the fallback signing secret. The plugin now fails closed when AUTH_KEY salts are not configured.
Public failure codes coarsened; detailed reasons now live only in the audit log (S-4).
Added uninstall.php to fully remove the audit-log option on plugin deletion (S-6).
Deactivation hook clears any in-flight impersonation cookie (S-6).
Reworked the user-edit screen UI to use a single dedicated form-table instead of a stray <tr> injection (L-4).
