  "mechanism": "As conditions or internal dynamics vary, ongoing adjustments contribute to keeping a form or function, and the same underlying method can make those adjustments without being replaced. Both a continuing form or function and adjustments that sustain it must be present; mere change, mere persistence, or accidental similarity across states is not an instance, and a rigid structure that withstands a disturbance without changing is not one either.",

    "Adjustment read as instability: visible adjustment that sustains continuity is called instability.",
    "Survival read as adaptation: anything that survives is called adaptive, even when no adjustment sustains it.",
    "Steadiness read as headroom: a form held steady by adjustment is taken to show spare capacity, when the adjustments may be close to their limit."
