CONTINUITY
Agent dies.
Work may continue.
Agents are expendable.
The mission is not.
Change the agent. Keep the work. Kawa preserves continuity, authority, evidence, and outcomes across humans, models, runtimes, and machines.
Continuity is not immortality. Participants are mortal. Missions may end. Authority expires. Understanding is rebuilt. History remains.
ゆく河の流れは絶えずして、しかももとの水にあらず。
よどみに浮かぶうたかたは、かつ消えかつ結びて、久しくとどまりたるためしなし。The flowing river never ceases, and yet the water is never the same.— Kamo no Chōmei, Hōjōki (1212)
A lineage can split into parallel Basins, parallel Basins can merge, some branches terminate, and the visible center can move to another lane. Records accumulate beneath each lineage and remain after that lineage ends: semantic death is not historical deletion.
Kawa is an event-sourced continuity and authority substrate for organizations where humans and AI agents act over time. It preserves what happened, why decisions were made, what evidence supported them, who was allowed to act, and what outcomes were recorded.
Agent dies.
Work may continue.
Mission may end.
Authority may expire.
The center changes with the generation.
Participants vanish.
History remains.
