Converted, refined, and re-sliced both LLA tracks from the tape with the
tester-round rules (passage->DIALOGUE+REFERENCE splits, vocab on the first
teaching line, sentence-sized read-only cards, merged-beat detection with
best-of-two sampling, repair loop hard-gated on figure coverage).
Book 10 masters now include tape lessons 2C-4D — ten lessons of audio content
the earlier masters never shipped (they used only 1A-2B). All ten masters
lint clean, 100% cassette coverage on every taped lesson.

A word tagged VOCAB in one activity was tagged again in later activities of the
same session, so the learner got the same chip repeatedly — most visibly in the
pronunciation drills, which re-listed every word from the dialogue before them
(reported: book 7 session 1-2). Rule applied: drop a VOCAB whose word was
already tagged in an EARLIER activity of that session. Repeats INSIDE one
activity are kept — those teach distinct senses ('stuck to his finger' vs
'stuck the milk in the fridge', 'shop' as verb then noun). Also dropped chips
for plurals of already-known words in book 7 session 1-2, where the drill
teaches the singular/plural pair rather than new vocabulary. No session lost
all of its vocabulary (verified).
