Provenance Record

Tight, well-framed semiconductor News piece (596 words) on Samsung's HBM5 mockup and the broader thermal-management contest, with all sources on the allowlist (the bot rebuilt the article on allowlisted outlets after dropping off-allowlist ones).

All 3 snapshots read from disk (HTTP 200; two via Archive.org fallback). source-0 (Tom's Hardware, Samsung HBM5) confirms verbatim 'eighth-generation', 'Heat Path Block', the HPB thermal-pillars quote, the 'concentrates on the D2D PHY layer… increase exponentially' quote, the '2nm … down from the 4nm node used for HBM4 and HBM4E' quote, and the before-2028 timing. source-1 (TrendForce) confirms the 12/16/20-layer stack options, the 'an independent thermal path within the D2D PHY region' quote, and the ~2028 production window. source-2 (Tom's Hardware, SK hynix iHBM) confirms the 'from next-generation products, such as HBM5' quote verbatim.

The Samsung HBM5 story — every quote and specific (Heat Path Block, D2D PHY, 2nm base die, stack options, 2028) — is verbatim and fully verified. One issue in the secondary SK hynix paragraph: the article's quote 'cooling elements made of electrically non-conductive, thermally conductive silicon … cuts thermal resistance by more than 30% against current products' is not verbatim — the cited snapshot says 'non-conductive silicon cooling elements' and 'cut thermal resistance by 30%' (the source's headline and URL both say 'by 30%', not 'more than 30%'). The substance is accurate; the wording was embellished and the figure inflated. Filed as a correction.

Substantively accurate; APPROVE_WITH_CORRECTIONS for the single embellished SK hynix quote.
