     "IT ALSO CORRECTED THE BRIEF THAT SENT SOMEONE TO FIX IT. The work item stated that a bare String initializer projects no atom identity WHILE A LIST-LITERAL INITIALIZER DOES, and scoped the repair to making the bare position behave like the list position. There is no such discriminator: both shapes are value-blind. Building the briefed repair would have copied a projection that also drops the value, and the discovery gate would have stayed blind while the change reported the blind spot closed — a false green on the exact axis the work existed to fix. The reading consistent with every measurement is that what surfaced for the list specimen was ExprRecordLit CONSTRUCTOR SPELLING, which v2.std.decl_facts_skeleton decl_facts_outer_record_constructor_lexeme_authority_note already records as spelling and explicitly not identity — spelling surfaces, authored values never do. A brief that names a discriminator is a measurement claim and is owed a reproduction before it is owed an implementation.",
 
-    "RUNG FOUND AT: mitigation by review — nothing refuses, and the gap was found only because a consumer's green was distrusted and re-measured. ATTAINABLE CEILING: structurally guaranteed. The question 'does this declaration fact carry the authored value' is decidable and fully modelled, so once the projection carries values a lexeme-keyed reader cannot be blind to a value that is present, and the class stops depending on anyone remembering to check. NEXT-RUNG TRIGGER, named as the CAPABILITY and not as an artifact that would contribute to one: DataItem declaration facts carrying authored string values through decl_facts_at, sufficient for a lexeme-keyed consumer to distinguish two rows by what they author. A projection change that carries values for one initializer shape does NOT satisfy it, because a per-shape answer has the same blind spot as none — which is the error the originating brief made.",
