+#!/usr/bin/env bash
+#
+# scrub-history.sh — purge the leaked credentials from this repo's git history.
+#
+# ⚠️ ROTATION FIRST. This repo is public and the secrets are already cloned/cached/
+#    indexed elsewhere. Rewriting history does NOT undo the exposure — you MUST still
+#    rotate every key (Infura, ETH_PRIVATE_KEY 0x075F227E…, Pimlico). This script is
+#    optional hygiene to stop re-leaking them on fresh clones, not a substitute for rotation.
+#
+# ⚠️ DESTRUCTIVE. It rewrites EVERY commit hash. After running you must force-push and
+#    every collaborator must re-clone (old clones keep the secrets and will reintroduce them).
+#
+# The leaked secrets are NOT hardcoded here — they're extracted from history at runtime
+# into a .git-local (never-committed) replacements file, which is deleted afterward.
+#
+# Usage:
+#   bash scripts/security/scrub-history.sh           # dry-run: show what would be scrubbed
+#   bash scripts/security/scrub-history.sh --run     # actually rewrite history
+#
