Once Value Coordination Report

Commit a write-once value on the first attempt and report how many later writes were rejected.

const writes = 3;

function coordinate(count) {
    for (let i = 1; i <= count; i++) {
        if (value === -1) {
            value = i * 10;
            commits += 1;

    if (commits >= 1 && rejected >= 1) {
        outcome = "guarded";
    } else if (commits >= 1) {
        outcome = "sealed";

coordinate(writes);

write-once value A write-once value accepts the first commit and ignores the rest, keeping the stored value and commit count deterministic.
