If you name a session and another session running on the same machine already goes by that name, the new one yields the name, takes a suffixed variant, and warns you. Anything already talking to that session over its local socket is told the new name so it keeps addressing the right one. Turned on by the remote flag tengu_session_name_uniqueness, whose built-in fallback is on.
- The outcome of each naming attempt is recorded as one of: kept the name, held it, yielded it, was superseded, or already decided earlier.
- Startup checks the name you passed in, re-checks interactively, and runs the same check again on rename; names supplied by hooks are checked against the yield record before being applied or cached.
- The registry of live sessions now also records when each name was taken.
- If the registry cannot be read, the notice to other sessions is skipped and a debug line is logged instead.

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 v2.1.232. 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.
