tengu_pewter_lintel
A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.283 and was gone by v2.1.284.
Several keypresses arriving at once can now be drawn one by one without setting CLAUDE_CODE_COMMIT_BETWEEN_KEYS
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.283.

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
2The earliest release whose published evidence quoted tengu_pewter_lintel was v2.1.283, 25 Sep 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.
Presence across releases
2Build by build
24One 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.
