It saves that list in the session's internal metadata, which is information stored alongside the session. It also records:\n\n- when artifacts, memory and sessions are touched\n\n- which MCP server a tool came from\n\nA server-side switch controls the recording. It is on unless it is turned off remotely. In a reading taken before this release, it was off for this site's account and for an anonymous account.\n\n**Why**\n\nThis is new information kept about each session, and its built-in default is on.\n\n- Flag `tengu_gentle_sphinx`: Off in both readings (read for one account on one subscription tier against v2.1.323; 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: Nothing to try yet\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
