The Z card is the required checksum over the rest of the artifact.

<h2>8.0 Remarks</h2>

A remark artifact holds textual remarks that are added to a check-in
or branch.
Remarks can hold expanded commentary about the check-in, a description
about the purpose of a branch, notes from
code-reviews, information about problems discovered in the check-in
or branch, or other auxiliary textual information about the check-ins
and branches.
The remark artifact is a new artifact added to this specification in
early 2017.
The following cards are allowed on a remark artifact:

<blockquote>
<b>D</b> <i>time-and-date-stamp</i><br />
<b>G</b> <i>checkin-or-branch</i><br />
<b>N</b> <i>mimetype</i><br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>
</blockquote>

A single D card is required to give the date and time when the
remark artifact was created.

A single G card specifies the object to which the remark is attached.
If the argment is a 40-character SHA1 hash, then it identifies a
check-in.  Otherwise, the argument is the name of a branch.  Since
branch names may whitespace, the argument to the G card is encoded
in the same way as a C-card.

The optional N card specifies the mimetype of the text of the remark
that is contained in the W card.  If the N card is omitted, then the
W card text mimetype is assumed to be text/x-fossil, which is the
Fossil wiki format.

A single W card provides wiki text for the document associated with the
