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.

First-Party Guard on Saffron Lattice Eligibility

Feature flag
tengu_saffron_lattice 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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.177: not a boolean we can read

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 v2.1.177. It isn't a statement about your account. What a flag value here can and cannot tell you

The function that checks whether a user is eligible for the saffron lattice (progressive-rollout update) feature now requires the installation to be a first-party build (l6() !== "firstParty" returns early). Previously this check was absent, meaning third-party or forked builds could inadvertently enter the saffron lattice update path.

Evidence

New guard in eligibility check (search for "firstParty" near tengu_saffron_lattice)

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