+"""Differential + regression coverage for rsync's delete timing.
+
+``--delete-during``/``--delete-delay`` stream a per-directory delete plan instead
+of one whole-tree manifest, so the timing is observable:
+
+  * ``--delete-during`` removes a directory's extras as it processes that
+    directory (so an interrupted transfer has already removed the extras of the
+    directories it reached);
+  * ``--delete-delay`` snapshots those extras while scanning and commits the
+    removals only after a fully-successful transfer (so an extra created in the
+    destination after its directory's plan survives, and a failed transfer
+    removes nothing);
+  * ``--delete-after`` re-scans the destination at the end (so that same
+    late-created extra is removed).
+
+The final-state tests compare against real ``rsync 3.4.1`` where a deterministic
+comparison exists; the timing tests use a byte-slicing proxy to force a
+mid-transfer failure or to create a destination entry while the transfer is in
+flight.
