Every name Claude Code reads.

Not the names we happened to write about. The names that are actually in the build, read out of the shipped bundle release by release, and kept here after they disappear again. Eight kinds of them, 5,592 in all.

A family reading not read yet is one whose miner has not landed. The name is real, the route is real, and the list fills in on the release after the inventory learns to read it.

420 of them have no description from anybody: not a line in Anthropic's documentation, not a changelog entry of ours that names them, and not a model's reading of the bundle. They are in the build and nobody has ever said what they do.

1 feature story read the other way round: one feature, followed through every release that changed it, instead of one release at a time.

Every name, with its span

52 of 5,592 names

First and last are the builds an inventory was read out of, not the day anybody wrote the name down. Builds counts the 149 on this box, the newest of them v2.1.308.
