A prior ClickHouse to Datastore rename rewrote `github.com/ClickHouse/ClickHouse` to `github.com/Datastore/Datastore`, a repository that does not exist. That turned 162 references across 131 files into dead links, and turned captured stack traces and historical changelogs into false statements. A citation of upstream is a fact, not branding. Product surfaces keep the Hanzo Datastore name; references to the upstream project point at the upstream project. Also untracks `.claude/`, agent scratch that was never meant to be committed.
