[[claim-memory-wall-named-1994-wulf-mckee]] rests its load-bearing historical claim — *who* named the memory wall, *when*, and *how they framed it* — on a Tier-3 university press page (UVA Today). The sourcing floor allows Tier 3–4 for uncontested history, but escalates to Tier 1–2 when the fact is the load-bearing point of a note, which it is here. The note is held at `seedling` until the primary is pulled.

Specific verification needed:

- **Pull the Wulf & McKee primary.** The paper is commonly cited as W. A. Wulf and S. A. McKee, "Hitting the Memory Wall: Implications of the Obvious," *ACM SIGARCH Computer Architecture News*, 23(1), 1995. Confirm the exact title, authors, venue, volume/issue, and year, and whether "1994" (the capture's stated coining date) vs. "1995" (likely publication date) is the right attribution.
- **Confirm the affiliation and roles.** That McKee was Wulf's graduate student at the University of Virginia at the time.
- **Confirm the framing verbatim.** That the paper attributes the wall to the divergence between CPU speed growth and DRAM latency/bandwidth growth (single-digit %/year), rather than the paraphrase carried by the UVA press page.

Why it matters: the memory wall is the historical anchor for the whole cluster ([[claim-processing-in-memory-beats-memory-wall-dna-alignment]], [[claim-ertl-memory-wall-fallacy-application-dependent]], and the LLM-inference notes). A verbatim primary quote moves the anchor note off `seedling` and lets the cluster cite the origin directly instead of through a press release.
