Returns an id, never text.\n *\n * \ud83d\udd34 REWRITTEN 2026-08-25 ON THE OWNER'S INSTRUCTION. What it replaced could\n * concatenate up to three sentences, and the mesh sentence \u2014 \"Our analysis\n * flagged a few points on this design\" \u2014 fired on 9 of the 19 regression\n * fixtures, as often as \"everything is fine\". His words: *\"this message is\n * repetitive in most of the results and weak even good printable parts\"*, and\n * *\"try to combine notes in only one \u2026 always try to have a message less than\n * 2 lines\"*.\n *\n * The four rules it now follows, in his order of priority:\n *\n *   1. ONE note. Never a paragraph. Every message is a single sentence that\n *      fits in two lines.\n *   2. IT MUST NEVER READ AS A REASON NOT TO ORDER. *\"this printability\n *      shouldn't be a marketing blocking action, user should always be\n *      confident that we solve everything\"*. So a minor finding says we handle\n *      it and nothing is needed; a serious one says place the order anyway and\n *      we will make contact.\n *   3. MESH FAULTS ARE MOSTLY THE FILE, NOT THE DESIGN, so they are silent\n *      unless the file is genuinely not a closed solid. There is deliberately\n *      no `minor_mesh`.\n *   4. IF WE CANNOT PRICE IT HONESTLY, SAY SO AND GET NOTIFIED. That is the one\n *      case where the team is alerted (an order note at checkout) and where we\n *      promise a call.\n *\n * \u26a0\ufe0f When more than one thing fires, the note becomes the generic \"several\"\n * wording rather than gluing subjects together. Building \"thin walls and\n * overhangs\" from fragments is exactly the sentence-splitting this project\n * forbids: French and Arabic word order and agreement do not survive it.
