- MISSING_ALTERNATIVES (63/64 applied): uncontracted/contracted forms, digit
variants (05|5), synonyms and full-sentence variants, via ACCEPT lines and
inline gap alternatives; skipped 'better/fine' for the Opposites drill (not
opposites of "sick").
- NOT_DERIVABLE (16 fixed, 10 false alarms, 1 skipped): item-level fixes
(visible word hints, missing premise, speaker clarifications "Joe (to Jim):",
emphasis/cue corrections, un-gapped unguessable words, rounded-number
accepts); converted the two book-10 paragraph clozes (Mary / The Mall) from
CHECK: exact to CHECK: llm with logical-completion rubrics; cross-book
recycled vocab (pilot, teller, barber, variety store, ...) left alone.
- UNCLEAR_TARGET (10): instruction/intro corrections (Food "Type the word for
the food.", Explain-with-Too intro), cue/emphasis fixes.
- Rubric rewrites (57): applied audit-suggested grader rubrics (now effective
with the pre-item RUBRIC parser fix); moved the two per-item rubrics of
book-11 "Write the Main Idea" inside their items.
No clip-bearing line changed; all masters validate (0 errors, 0 new warnings)
and pass stage-master clip-identity checks. Full decision log:

Added a firm guide rule: drop a cassette activity ONLY to dissolve a
bare word-list or remove a true duplicate; keep every other. This cut
over-dropping sharply (book-4-lesson-3: 83 -> 6 dropped clips, all the
sanctioned word-list; book-1-lesson-2: 49 -> 22). Generated the Book-1
review ST images so book-1-lesson-5 can ship. All 10 masters now live.
