Provenance Record

Clean, well-structured 588-word News piece with a clear Overview / What We Know / What We Don't Know / Analysis arc. Technical depth is appropriate and every figure is attributed to a named source. IDC is correctly and explicitly credited as the source of the No. 1 ranking claim throughout.

Two source snapshots read from disk, both fetched successfully (HTTP 200), no fallbacks. source-0.html.gz (SDxCentral, 'Nvidia tops Ethernet data center switch charts by revenue as sales soar', June 22 2026) — CONFIRMED: Nvidia share surged 192.7% YoY to $2.1B for a 21.5% data center segment share and the top revenue spot; data center segment grew 61.0% YoY to $10B; 800G at 35.8% of DC revenues; Arista grew 37.3% YoY holding 20.7% of the DC segment; Cisco DC revenues +43.0% YoY; both Nicholson quotes appear verbatim. source-1.html.gz (IDC blog, 'NVIDIA Becomes #1 in Datacenter Ethernet Switching as 1Q26 Market Surges 39.8% to $15.4 Billion') — CONFIRMED: worldwide Ethernet switch revenue $15.4B up 39.8% YoY; Nvidia $2.1B / 21.5% DC share / +192.7% YoY / #1 by revenue for the first time; Spectrum-X described verbatim as an end-to-end AI networking solution integrating Spectrum Ethernet switches with BlueField DPUs and NVIDIA LinkX cables purpose-built for large-scale GPU clusters; both Nicholson quotes verbatim. Every load-bearing number, share %, YoY growth figure, and the total market size all trace exactly to the snapshots.

No hallucinations, no misattributed quotes, no fabricated specifics. Both direct Nicholson quotes match the snapshots word-for-word. The 21.5% (Nvidia) vs 20.7% (Arista) data center segment shares correctly support the 'narrowly ahead' / 'edging Arista' framing. The article carefully scopes Arista's 20.7% to the data center segment (Arista's total-market share is 14.6%), avoiding the common conflation error. The internal link to the Cisco Silicon One G300 article resolves to an existing published article.

APPROVE. A clean, accurate, well-sourced market-share story where every specific traces verbatim to a cited snapshot and IDC is properly attributed as the source of the ranking. The lone flag is an off-allowlist (but authoritative) idc.com source, which is an editorial warning rather than a correctable factual defect, so no corrections record is warranted.
