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.

Source Researched timeline merged with the Factbook Historical Context decomposition. Recent events are drawn from web search and summarised rather than quoted; historical events are established record. Where the two sources described the same development the fuller entry was kept, taking the more precise date from the other. Neither carries citations yet.
