The fork note requires the harbor-kite gate or CLAUDE_CODE_HARBOR_KITE and is skipped on Windows.
When a session is detected as a copy of another that is still live, a one-time note is queued for the model explaining that history up to the fork point is shared, that the two have since diverged, and how to find and message the sibling. Requires the tengu_harbor_kite gate (fallback false) or CLAUDE_CODE_HARBOR_KITE, and is skipped on Windows.
- Suppresses itself if the note is already in the conversation or already queued.
- Reported as
fork_source_note, with aparent_gonereason when the original session cannot be resolved.
This session began as a fork (copy) of another session that is still running
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_harbor_kite Off by default, switched on for this accountThe shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.
This account: on · anonymous baseline: on · compiled default in v2.1.224: off
These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
Read once, for one account on one subscription tier, against v2.1.224. It isn't a statement about your account. What a flag value here can and cannot tell you
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.
