Timeline

Every development graded as belonging to this capability, wherever it is kept: very high (about it), high (directly and substantially changes it), medium (a direct, material effect on it). A model gave the grades, reading each entry against the framework. A structured starting point, not a cited record. An entry marked unverified has not been checked against a source; tiers are assigned by a model and are not comparable between nation and capability timelines.
