• Do Bak, Tang & Wiesenfeld's own 1987/88 papers and Bak's How Nature Works state self-organized criticality's tuning threshold as 'necessary' rather than 'necessary but not sufficient'?

• Per Bak's *How Nature Works* independently confirms self-organized criticality needs no external tuning, and reserves the word 'necessary' for the non-SOC systems SOC is contrasted against

• The 'necessary/sufficient' framing of self-organized criticality's threshold is absent from the primary record — neither BTW's 1988 paper nor Bak's book uses that vocabulary, marking it a secondary-literature construct

• Does the SOC primary literature confirm that self-organized criticality requires no external parameter tuning and that local thresholds are 'necessary but not sufficient'?

• Bak, Tang & Wiesenfeld's 1987 paper states, in their own words, that self-organized criticality's critical point is reached without tuning any external control parameter

• BTW's own papers state that every local site sitting near threshold is a coincidental feature of the one-dimensional sandpile, not a general signature of self-organized criticality
