Explanation text for a disabled 'live-subscribe' artifact-watch feature was reworded

What

The feature that lets a session track republishes of a watched artifact is controlled by a flag called tengu_slate_lantern. When that flag resolves to false, the reason given is flag_off; this release only changed the wording of the explanation shown in that case, not the underlying logic.

Why

This is a text-only change to how the disabled state is explained. The flag itself has been read as on for this site's account and on for the general anonymous baseline in past checks, but no reading has been taken under this specific release.

tengu_slate_lantern Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

This account: on · anonymous baseline: on · compiled default in v2.1.274: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.274. It isn't a statement about your account. What a flag value here can and cannot tell you
