This is a new, more general cleanup step than the one covered before, and it only runs when a setting called `tengu_silly_waterfall` is turned on for the account.\n\nThe flag was off for both this site's account and the general population, and no reading has been taken under this release yet.\n\n**Why**\n\nWhen enabled, this keeps the visible conversation history free of leftover or duplicated entries that don't belong, so the transcript reads cleanly.\n\n- Flag `tengu_silly_waterfall`: Off in both readings (read for one account on one subscription tier against v2.1.273; this account: off, anonymous baseline: off, compiled default: 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.\n- Area: Transcript\n- Tier: Nothing to try yet\n- Useful: 2\/5\n- Signal: 2\/5\n- Present in the build but not switched on"}
