+# Description:
+# Verify redaction works as expected for various scenarios.
+#
+# Strategy:
+# 1. An unmodified file does not get redacted at all.
+# 2. Empty redaction list redacts everything.
+# 3. A file removed in the clone redacts the whole file.
+# 4. A file moved in the clone does not redact the file.
+# 5. A copied, then removed file in the clone redacts the whole file.
+# 6. Overwriting a file with identical contents redacts the file.
+# 7. A partially modified block redacts the entire block.
+# 8. Only overlapping areas of modified ranges are redacted.
+# 9. Send from the root dataset of a pool work correctly.
