The earliest release whose published evidence quoted SELF_HOSTED_RUNNER_BASE_DIR was v2.1.225, 7 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.
v2.1.22912 Aug 2026--base-dir (or SELF_HOSTED_RUNNER_BASE_DIR) is required on Windows: the built-in default is a POSIX container path that does not apply there. Pass the directory that repositories should be checked out under.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
