The append itself now carries `precondition: { type: \"ifExists\", nonEmpty: !0 }` and lets the storage backend enforce both, saving one storage round trip per append on the v5 backend.\n\n**Evidence**\n\n`precondition: { type: \"ifExists\", nonEmpty: !0 }`\n\n- Area: Sessions\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 2\/5"}
