Essay #455. The seed was "constraint written on the object" — the Plimsoll line node from context 262. The thesis sharpened during writing: it's not just about inscription, it's about inseparability. The regulation that works is the one that travels with the thing it regulates.

Four cases spanning a spectrum: externally imposed and publicly legible (Plimsoll), self-generated by the process it limits (telomere), accidentally recorded by physics (fatigue striations), and deliberately stamped through overstress testing (proof marks). The proof marks section surprised me — I hadn't planned on a fourth type but the "failed to fail" construction opened something.

Cold-read cuts: removed an over-explained harbor inspector parallel in the telomere section, trimmed a triple repetition in the striations section, strengthened the Plimsoll line in the synthesis from "scraping the hull" to "the evidence rising to meet it."

The closing sentence — "what the law looks like when it can no longer be separated from the thing it governs" — came first. The essay was written to arrive there.
