  "what_this_implies": "The identity is not observable as pre-registered, which is the same classification already applied to treasury_auction_concession. The next step is an identity REDESIGN with its own pre-registration -- an initial Form 10 evidently does not carry distribution mechanics at the rate this protocol assumed, and any redesign must name the document that does before it names a threshold. Lowering the threshold on the existing protocol would be fitting the gate to the result.",
  "why": "Only 11 of 98 documents contain a pro-rata token in ANY written form (11.2%), and only 5 contain one near a distribution reference (5.1%). The gate asks for 30%. A perfect detector therefore reaches at most 11.2%: the shortfall is not extraction, it is that this language is not in these documents. Widening the pattern until the number cleared would have been tuning a measurement to agree with a target.",
