 The aggregate commit is a reproducibility aid, not an editorial signoff. Capital arrangements with ambiguity or recent change are explicitly marked and removed from one-answer question eligibility.
 
+Land-border draft facts use the REST Countries V4 data pinned at commit `43f6260db10c54df9972e6e554ee14c2e7c85ef5`. These are concise fallback copy, not inferred lessons about UN regions. Editors must check disputed boundaries and whether overseas territories affect a claim before approval.
+
+The early-play pool has twelve more varied draft facts sourced directly from public institutions: Geoscience Australia, Brazil's IBGE, the governments of Canada, India, Japan, Mexico, South Africa, New Zealand, Nepal and the Netherlands, Royal Museums Greenwich, and the archived CIA World Factbook. Their exact page URLs and retrieval snapshots are recorded in the catalog. A source link proves provenance; it does not constitute fact or copy approval.

+# Feedback voice recommendations
+
+Duolingo's public product writing consistently puts the answer first, keeps the immediate interaction small, offers explanation as a second layer, and makes the end of a session encouraging while still naming what needs practice. That pattern is useful here, but Bert's Atlas should keep an original travel-and-curiosity voice rather than imitate Duolingo's phrases.
+
+Research basis:
+
+- Duolingo, “Explain My Answer is now free for all learners”: https://blog.duolingo.com/explain-my-answer-now-free/
+- Duolingo, “Introducing Duolingo Flashcards”: https://blog.duolingo.com/duolingo-flashcards/
+- Duolingo 101: https://blog.duolingo.com/duolingo-101-how-to-learn-a-language-on-duolingo/
+- Duolingo, “How we improved the streak”: https://blog.duolingo.com/improving-the-streak/
+
+Recommended original patterns:
+
+- Correct: “Flag filed. Nice work.”
+- Incorrect: “That was {answer}. Look for {short distinction}.”
+- Overtime: “Time's up. You still found it.”
+- Continent hint: “Map clue: {continent}.”
+- Choice hint: “Two decoys are leaving.”
+- Fact hint: “Bert's clue: {answer-safe fact}.”
+- Results: “Atlas packed: {score} points · {accuracy}%.”
+- Review: “Worth another look: {countries}.”
+- Streak: “{days} curious days in a row.”
+
+Keep feedback to one idea per line. Name the correct answer after a miss, but never include it in a pre-answer clue. Avoid shame, exaggerated celebration, and claims that a streak proves mastery.
