Module 6 practice · account for selected evidence

Use the lesson before the solutions.

A. Predict a budget. Ranked passages A, B and C contain 150, 30 and 40 quote characters. The budget is 80. Under the taught whole-passage skip rule, which fit, how many quote characters are used, and which ID is skipped? If labeled required evidence is {A,B}, what is packet coverage? Can the selector legitimately read that relevant set to improve the reported comparison?

B. Reproduce the loss. Run methods.py context. Record selected IDs and labeled coverage at budgets 80, 120 and 400. Explain why the retrieval candidate set can remain identical. State three things excluded from the quote-character budget and what a later real-model input counter would need instead.

C. Source ambiguity. Two current public records share source synthetic://hours and versions 9 and 10. They give different opening schedules. Explain the context rule's response and why sorting strings is not an authority policy. Name a different contradiction this rule would fail to detect.

D. Duplicate text. Two top-ranked IDs have exactly the same quote text, followed by a needed second-source passage. Explain what exact-text deduplication changes and what authority question it cannot settle. Would overlapping but non-identical chunks be removed by this implementation?

Self-review: predict the budget exactly, preserve denominators, explain authority limits and distinguish actual character selection from unrun neural token/position experiments.
