Hand over the command where the parity page counted the tree

[iderex]

Refs #363

Finishes: #363

What was wrong

git show 74f5d62:docs/gate-parity.md | sed -n '95,98p'
This repository has eight tracked files inside that glob:

    git ls-files | grep -Eic '\.(js|html|md|css|scss)$'
    8

git ls-files | grep -Eic '\.(js|html|md|css|scss)$'
24

The number was right when it was written and has not been touched since:

git log --format='%h %ad %s' --date=short 74f5d62 -S"This repository has eight tracked files inside that glob" -- docs/gate-parity.md
03dd447 2026-08-06 Quote the parity numbers from the commit under review

git ls-tree -r --name-only 03dd447 | grep -Eic '\.(js|html|md|css|scss)$'
8
git ls-tree -r --name-only 74f5d62 | grep -Eic '\.(js|html|md|css|scss)$'
24

So the tree tripled under the sentence over a month and nothing reddened.

What it says now

The count is deleted rather than corrected and the command is handed to the
reader. That is not an invented repair: the mutation section of this same file
took it three sections down, for a count of the plugin's files that drifted the
same way, and says why in its own words - nothing here reads a figure in a
document, so the command is handed over in place of its output.

The paragraph's own argument is what the number was there to illustrate, and it
survives without it: the count includes this document, which is why it was first
written as seven, and it was taken before the file holding it was added. The
row's conclusion never turned on the size of the count, only on it not being
zero, and the closing sentence now says exactly that.

The third condition, which is the other figures

Read in the same pass. None has moved.

The two required-set counts are dated to 2026-08-06 in the text and already tell
a reader to re-run the commands rather than quote them, which is the shape this
change gives the prettier count.

The sign-off row's count and the target's commit date are read at pinned refs
rather than at a branch, and both reproduce:

gh api 'repos/iderex/jellyfin-plugin-sso/contents/.github/workflows/dco.yml?ref=e9cee021e95763e5240b44b8d7af16598df609ce' --jq '.content' | base64 -d | grep -c 'expected="Signed-off-by: ${author_name} <${author_email}>"'

What holds it, which is nothing, and the residual that leaves

No leg is added and none is claimed. Nothing in this repository reads
docs/gate-parity.md at all - it is not among the documents the suite is
given - so the next figure typed into it goes stale exactly the same way. #363's
done-condition offers a derived leg as the alternative to deletion; a leg would
mean giving the suite a reading of a document whose whole subject is a comparison
against another board's tree, which is a larger decision than this repair and is
not taken here.

per target, over both server lines, before the change and after it.

Reading

No second reader looked at this. The commands above are the evidence in place of
one.
