Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Tab-aware read separator still off, and its value no longer sticky

The tab-aware read separator flag is read fresh each time but still off.

tengu_tab_read_sep fallback is off; only remote config enables it.

Feature flag
tengu_tab_read_sep Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.248: not a boolean we can read

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The tengu_tab_read_sep flag is now read fresh on each call through a small accessor rather than cached once per session. The compiled fallback is off, so the feature is still disabled unless remote config turns it on.

Evidence

tengu_tab_read_sep

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
