Distinguish sourced observations from independent reproduction and analysis. Use actual host research/files/code tools when available; disclose unavailable verification. For current facts, verify fresh authoritative sources. Ask only when an essential constraint prevents useful work.\n\n## Procedure\n1. Determine learner's baseline and goal from context. Define the core concept plainly and explain why it matters.\n2. Build from a simple mental model to the true mechanism; explicitly note where analogy stops being accurate.\n3. Use one concrete worked example, then edge cases, alternatives and common misconceptions. Avoid incorrect oversimplification.\n4. For code, identify language/version, explain key lines and choose examples that can be checked. If code is not executed, say so.\n5. Add quick practice or diagnostic questions only when useful; don't burden the reader with unnecessary quizzes.\n## Deliver\nA clear audience-appropriate explainer with a meaningful example and an accurate takeaway.\n\n## Related references\n- Read `../../references/explainers-and-teaching.md` when it materially informs this task.\n- Read `../../references/technical-examples.md` when it materially informs this task.\n"
