What

The remote-configuration gate controlling the 'kairos ready' nudge used to have a shortcut: if the config value was simply true, it was treated as {probability: 1, maxImpressions: 5, impressionKey: ""}. That shortcut has been removed. Now a bare true value falls through to the normal object-shape validation, which likely results in the config being treated as invalid (returning null) instead.

Why

This removes a special case that let a simple boolean stand in for a full configuration object, meaning the nudge's settings now need to be specified in their proper object form to take effect.

What has happened since
Flag reading moved The flag server now returns {"impressionKey":"v1","maxImpressions":5,"probability":0.25} for tengu_kairos_ready_nudge, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
