The artifact type catalog's override variable and internal flag were renamed

What

An internal feature related to Artifacts (browsing published artifact types) had its override environment variable and internal feature flag renamed: CLAUDE_CODE_ARTIFACT_DB became CLAUDE_CODE_ARTIFACT_TYPE_CATALOG, and the underlying flag went from tengu_umber_lattice to tengu_cobalt_plinth_larch. Both still default to off unless a value is supplied.

Why

This is a naming cleanup for a feature that lets Claude browse and describe published artifact types to start new work from; the rename doesn't change whether the feature is on, only what it's called internally.

Names in the bundleCLAUDE_CODE_ARTIFACT_TYPE_CATALOG
Feature flag
tengu_cobalt_plinth_larch 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_umber_lattice On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.
