A new internal check flags any non-empty string value other than 'empty_store'

What

A new internal helper function checks a value and returns true only when that value is a piece of text (a string) and is not the specific placeholder text empty_store. This check is controlled by a new gate (an internal on/off switch called a feature flag) named tengu_typed_koala.

Why

This is an internal plumbing change with no described effect on what you can do in Claude Code; it's used somewhere to distinguish real stored values from an empty placeholder.

Feature flag
tengu_typed_koala 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.
