What probably matters to youSection of the release

Unclear Nothing has been read yet about the tengu_kestrel_moor gate, so whether this latch behavior is active for any account is unknown.

A new gate makes the client's atis value get read once per conversation into a latch, seeded only when the value is printable ASCII, instead of re-reading client data on every access. When the gate is off, the old behavior of reading it directly each time is kept.

What has happened since
Flag reading moved The flag server now returns off for tengu_kestrel_moor, 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.
