tengu_lapis_anchor_user_turn
A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.202, including the newest one read.
What it is
Claude now gets a running count of tokens left by default, re-anchored on each of your prompts.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.233.

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

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.
