Give timed landmarks (attachment, local seconds, quoted words). Then: mechanismsMatched[{mechanism,attachment1,attachment2,matched(boolean)}], defects[{localSeconds,words,problem,severity}], wordsMisheardOrUnclear[], whatCandidateDoesWell[], remainingGaps[]. Return ONLY JSON (no prose outside JSON), <=1900 words, English. Required keys: mediaAccess(boolean), audioAccess(boolean), attachmentsHeard[{attachment,firstWordsHeard,lastWordsHeard,durationEstimateSeconds}], then the analysis keys listed below. No script is supplied: quote only words you actually hear and mark uncertain words with (?). Use attachment number plus LOCAL seconds of that attachment. Do not rate quality with numbers, do not assume either language or the original is better, do not reward louder mastering, more notes or softer timbre. Identify concrete mechanisms, not taste."
