Claude Code now checks for files Claude read earlier that no longer appear in the memory listing. When it finds one, it can add a notice saying that the earlier `memory_read` result is stale.\n\nThe notice is controlled by a remote switch and applies only to one kind of session.\n\n**Why**\n\nClaude stops relying on notes that were deleted somewhere else.\n\n- Flag `tengu_gentle_ocean`: Not enough to say (read for one account on one subscription tier against v2.1.321; this account: no value returned, anonymous baseline: no value returned, 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: Memory\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
