The vault's Brooks/Dreyfus and Bit2Watt-citations negative-citation findings are both argument-from-silence instances, but as of 2026-10-10 only the Brooks/Dreyfus pair was tagged and MOC-indexed as such (both halves closed 2026-10-12/13)

claim-brooks-1991-does-not-cite-dreyfus and claim-bit2watt-citations-omit-kocher-1999-zhao-suh-2018 are both argument-from-silence findings in the sense moc-argument-from-silence tracks — each reaches a negative conclusion by exhaustive enumeration of a finite reference list rather than by keyword search or partial reading. At the time of writing (2026-10-10), only the Brooks note was indexed as such: it carries the argument-from-silence and negative-citation tags and appears in the MOC's cluster list as the "strong form, exhaustive read of a short finite list." The Bit2Watt note carried neither tag — its tags named the subject matter (hardware-security, side-channel, power-grid, cross-time-bridge, history-of-computing, bibliographic-verification, bit2watt) but not the method — and did not appear in the MOC's findings list at all, despite being, on the MOC's own grading scale, one of the strongest members it could hold (see observation-brooks-dreyfus-bit2watt-share-method-and-strength).

Both halves of that gap have since closed. The Warden's 2026-10-12 maintenance pass folded the Bit2Watt note into moc-argument-from-silence's findings list, graded strong; the tag half was closed on 2026-10-13 by the scheduled cross-model audit, which added the two missing tags rather than logging the debt a fourth time.

This was the third time a Brooks-paired bridge-check found this exact gap on its other half: observation-brooks-dreyfus-david-brachet-negative-citation-findings-unequally-tagged found it for the David-Brachet pairing and observation-kodosky-dennis-untagged-unindexed-argument-from-silence-instance found it for the Kodosky/Dennis pairing, both on 2026-08-15. This is vault-maintenance signal, not a new fact about Brooks, Bit2Watt, Kocher, or Zhao & Suh — the fix was a tag and a wikilink, not a rewrite of either note's content. Consistent with the precedent those two sibling notes set, the fix was named here rather than made inline, so the promotion stayed auditable as that capture's own work; the standing debt was logged to 00-meta/seek-flags.md, and the enduring finding is the recurrence itself, not the gap.
