# Day 18 — A small source has limits

**Purpose/codes:** Draw bounded conclusions and request fitting missing evidence; K01/S01/S03/S05. **Prepare:** O18 selected notes, F2/F3 date/source labels. **Child start:** “Can we really say that? Find the clue—or leave a question.”

1. **Invite:** O18 INVENTED 2022 pool-room repair note: a new bench was installed; two visitors wrote that they used it that afternoon. A claim says “Everyone liked the new bench forever.” Ask which parts exceed the notes.
2. **Model:** Replace with “Two visitors reported using the bench that afternoon; these notes do not tell us everyone's views or later use.” Missing mention does not prove absence; one day's report is not all future days.
3. **Guide:** F2 announced a future 2018 event; F3 reports a 2025 outcome. Neither establishes today's availability. Choose a fitting responsible current source for that different question; do not invent a present answer. No child web account or live scraping required.
4. **Choose:** Repair one overclaim and keep the supported part. An extension seeks a corroborating source, not forced searching.
5. **Check:** “Which words can stay? Which words need more evidence? What would you check?” Capture the exact repaired statement and reason.
6. **Next:** If the whole record is discarded, use an unrelated 2020 market note mentioning one repaired stall: keep that fact, withhold all-stall conclusions. If missing means zero, compare an explicitly complete inventory with a short selected list.

**Routes:** (a) **Claim repair shop:** cut or dictate replacement words on a claim strip. (b) **Fact/question pockets:** sort sentences into supported, not stated and needs checking, with a reason rather than a colour-only guess. (c) **Reader's challenge:** write a helpful “How do you know?” note for an overconfident fictional display; keep discussion private.

**Observation:** Retains actual supported information while limiting inference; not a blanket “nothing can be known” stance.
