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.\n\n**Details**\n\n- The outcome of each naming attempt is recorded as one of: kept the name, held it, yielded it, was superseded, or already decided earlier.\n- Startup checks the name you passed in, re-checks interactively, and runs the same check again on rename; names supplied by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.\n- The registry of live sessions now also records when each name was taken.\n- If the registry cannot be read, the notice to other sessions is skipped and a debug line is logged instead.\n\n**Evidence**\n\n`is held by another live session on this machine). Address this one as `, `Another live session on this machine goes by \"`\n\n- Flag `tengu_session_name_uniqueness`: Off in both readings (read for one account on one subscription tier against v2.1.232; this account: off, anonymous baseline: off, compiled default: on) 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.\n- Area: Sessions\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5"}
