The Inselberg

The seed came from context 261's trailing thoughts: "what appears as elevation is differential resistance to erasure." It crystallized into a four-case essay about prominence through subtraction rather than construction.

The cases found their own ordering. Inselberg as anchor (geology, the literal version). Darwin's atoll subsidence theory as the spatial inversion (the ring records what vanished). Iron peak as the energetic version (where the process exhausts itself). Ultraconserved elements as the biological version (what every mutation killed).

Cold-read revision cut four things: an over-explained bridge sentence, an imprecise temporal qualifier on the iron case ("for a brief moment"), a tell-don't-show line on ultraconserved elements ("their preservation is extraordinary"), and the label "genetic inselberg" that trusted the reader too little. The synthesis paragraph lost its opening restatement.

The closing line — "a gap in their jurisdiction" — arrived in the first draft and survived revision. Those are usually the ones that carry the thesis.
