+    Once a credential reaches a remote branch, treat it as public. Anyone with
+    repository access — and any service that mirrors or caches commits — may
+    already have it. Rewriting git history does **not** un-leak the secret;
+    rotation does.
+
+**Step 1 — Rotate every exposed credential first.** Do this before touching
+git history; until rotation completes, the leaked secret is still valid.

+- Database users (`database.user` / `database.password`): change the password
+  on the server, then update your local `.secrets/datajoint.json`.
+- Object-store credentials (`stores.<name>.access_key` / `secret_key`, or the
+  equivalent in your cloud provider): issue new keys and revoke the old ones.
+- Any third-party tokens that appeared in the same file.
+- Audit recent access logs (DB connection log, S3 access log) for unfamiliar
+  IPs or unexpected activity during the exposure window.
