tengu_federated_possum
A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.318, including the newest one read.
Set CLAUDE_CODE_PROGRAM_USE_CASE_ID and Claude Code can attach that use case ID to its requests, if the host accepts it
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.317.

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.
First cited
0No 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.
Presence across releases
1Build by build
5One 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 feature flag does. All feature flags.
