Across the named analyst-publication comparable set (Stratechery, The Information, the Substack analyst stack, the Big-4 research blogs, Gartner, Forrester, IDC) as of late April 2026, none maintains a public claim ledger — a tracked register of every primary claim with scheduled reviews, dated verdicts, and a public correction log. The absence is structural, not accidental, and explains why none of the category produces the kind of audit-able commentary the Holding-up system makes possible.

Build-log Issue 1. Names the comparable set per the editorial decision locked 28 Apr 2026 (1.A). Three review checks at 90 days: any comparable introduces tracked-claim mechanism, any vendor publication adds claim-tracking surface, or new entrant launches with ledger-as-default. None moved → Holds. Partial mechanism → Partial. Full equivalent → Not holding (and structural-distinction argument restates).
