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.

The atis latch is seeded once and only from printable ASCII

Under the hood
Useful1 Signal3
Client Config

The pinned atis value is set once per conversation and only accepts printable ASCII.

Feature flag
tengu_kestrel_moor 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.

Read once, for one account on one subscription tier, against v2.1.235. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The latch that pins the client atis value is seeded a single time per conversation and only accepts a value that is printable ASCII, which keeps stray bytes out of it.

Details
  • Gated on tengu_kestrel_moor, a remote flag whose fallback is on; with the gate off, each read goes straight to client data as before.
Evidence
