apply answerability-audit repair queue: ACCEPT variants, derivability fixes, rubric rewrites (46 masters)

- 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:
