That old check has been hardwired off, so it no longer does anything.\n\nThe same setting is now read in a new spot, with its default flipped from off to on, where it decides whether \"reactive compaction\" (a process that trims conversation history to save space) is allowed to fall back to an alternate method when needed.\n\n**Why**\n\nThis moves what the setting controls from a now-disabled auto-enable path to a live fallback decision for reactive compaction, so the setting still matters but for a different purpose than before.\n\n- Flag `tengu_hidden_frog`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.269; this account: on, anonymous baseline: on, compiled default: on)\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5"}
