+No diff since the versions are identical.
+
+
+The reconciliation script detects drift by comparing the files of interest. Notably any changes aside from the *current-state.txt* will be ignored. Desired state can also be altered and will become the new "source of truth", so this primitive approach will not guarantee drift prevention.

+Checksums are more reliable in terms of detecting discrepancies. Hashes guarantee identity of files as opposed to string comparisons used by (maybe custom) executables
+
+As stated above, this way of health monitoting and drift resolution is quite crude and unreliable
