Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. 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.

Three existing feature gates moved position; their defaults are unchanged.

Feature flag
tengu_ochre_wren 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.

tengu_ccr_orphan_restore_wake Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

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

CLAUDE_CODE_INTRO_FRAMECLAUDE_CODE_ACT_DONT_REDERIVE
What

For reference, since these moved position in this build: the intro frame reads CLAUDE_CODE_INTRO_FRAME and otherwise tengu_ochre_wren (off by default); the act-don't-rederive behaviour reads CLAUDE_CODE_ACT_DONT_REDERIVE and otherwise tengu_cedar_lantern (on); orphan restore wake uses tengu_ccr_orphan_restore_wake and tengu_ccr_orphan_restore_wake_shells (both on). All were already in v2.1.247 and remote config can still override each.

Evidence

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