Initial preservation checker stopped after copying the four files unchanged:

Traceback (most recent call last):
  File "C:\Users\User\Documents\Git\ARCADIA-Studio\harness\experiments\cli-prerelease-20260911\preserve.py", line 35, in <module>
    assert hashlib.sha256(notes).hexdigest() == publication['notes_sha256']
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError

The checker incorrectly assumed notes_sha256 meant local raw Markdown bytes.
Read-only comparison established that it instead exactly matches the LF public
release body. Local CRLF bytes remain preserved unchanged; CRLF-to-LF conversion
alone yields the public body and the publisher's recorded hash. The corrected
checker records both identities, without changing any publication asset or the
four source records. A subsequent temporary PowerShell comparison command had
an empty-pipeline parse error and was corrected before producing the comparison;
it made no file changes.
