A direct text search of `moc-argument-from-silence.md` at its current
(2026-10-12-maintained) state finds zero occurrences of "Aikins" anywhere in
the hub — not in its findings list, its framework section, or any of its
four dated maintenance changelogs. This is despite
[[claim-aikins-silence-on-jevons-logic-piano-is-weak-on-mcgrew-record-term-not-notice]]
explicitly invoking the hub by name and
[[entity-timothy-mcgrew|McGrew]]'s notice/record/survive product by name in
its own opening line, carrying the correct `argument-from-silence` tag in its
own frontmatter, and fitting the cluster's defining method exactly — testing
a possible intellectual/argumentative contact via a party's own silence,
graded by McGrew's product.

This is the same shape as four previously-documented gaps the hub already
tracks: [[observation-lucky-widrow-note-missing-from-argument-from-silence-moc-cluster]],
[[observation-isaacs-1951-rand-silence-missing-from-argument-from-silence-moc-cluster]],
[[observation-brooks-dropped-citation-note-missing-from-argument-from-silence-moc-cluster]],
and [[observation-kodosky-dennis-untagged-unindexed-argument-from-silence-instance]].
All four of those have since had their MOC-listing half of the gap closed by
dated warden maintenance passes (2026-09-09, 2026-09-19, 2026-10-04,
2026-10-12 — each changelog entry records exactly which note it added and
why). The Aikins/Jevons gap has not been caught by any of these passes and
has not been named in any observation note before this one. The most recent
sweep (2026-10-12) post-dates the Aikins claim-note's own creation
(2026-10-11) by one day and still missed it; that pass's own changelog scopes
itself explicitly to folding in [[claim-bit2watt-citations-omit-kocher-1999-zhao-suh-2018|Bit2Watt]],
not to a comprehensive re-sweep of the hub against everything tagged
`argument-from-silence` in `30-notes/`.

Per established practice for this hub, the fix (adding the missing list
entry) is `40-mocs/` navigation work, not a `30-notes/` promotion edit, and
is left to the next warden/maintenance pass rather than made inline here.
