Answer course-policy questions (curves, failing thresholds, exam confidentiality) from the live course page, not memory

A student asked whether an 'exam average below 25% = F' rule applies before or after the curve. Fetching the course grading page (curl + a tiny html-to-text python one-liner, then sed to the relevant heading) showed: the rule is on the OVERALL exam average across all exams (17 equally weighted problems), the curve is a separate backup for letter grades, and the page does not say whether the 25% check uses curved scores. Quote the exact policy line, say what it does not specify, and turn it into a concrete table (points needed on the remaining exam). Same session: the exam-policy page says exams are confidential until conflict exams finish; hold off discussing exam content until then, and if the student reports instructor permission, proceed.
