tengu_review_bughunter_configA Claude Code feature flag, read out of the shipped bundle.
It has been in the build since v2.1.138, including the newest one read.
The cloud review poll timeout is no longer hardcoded at 30 minutes and now comes from remote config.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.259 .

One row per unbroken stretch of one reading, newest first, from snapshots taken every twenty-five minutes or so. No longer carried is not off : it means the flag server stopped returning the gate at all, which is what a retired experiment looks like. The version column is what was installed when the reading was taken, not what caused it.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

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.
