- paper/compendium.tex + compendium.pdf: gentle textbook covering all
background for the notebook series — qubits, gates, magic states,
[[4,2,2]] code, stabilisers, error detection, ancilla measurement,
witness formula, noise, transpilation, scoring, ratchet optimisation,
lesson extraction, transfer evaluation. Includes glossary, math
appendix, and notebook cross-reference table.
- notebooks/learning_objectives.md: rewritten with balanced per-section
tables for all three plans (Plans B and C were previously stubs).
- 8 Jupyter notebooks across 3 learning plans (A: bottom-up, B: spiral, C: parallel tracks)
- Teaching toolkit (src/autoresearch_quantum/teaching/) with ipywidgets-based
quiz, predict_choice, reflect, and order widgets — visually distinct from code cells
- Fix spectator_z operator: was {1:'Z',2:'Z'} (IZZI, expectation=0), now {1:'Z',3:'Z'}
(ZIZI, expectation=+1 for ideal T-state, commutes with logical operators)
- Fix u_magic seed: swap phase arguments to match h_p and ry_rz preparations
- Fix double-display bug: widgets rendered twice when function returned the box
- Fix CLI override parser for negative integers and missing '=' validation
- Fix stabilizer detection quiz: ZZZZ detects X errors, not Z errors
- Add ties parameter to order() for questions with interchangeable items
- Expand test suite from 21 to 107 tests
- Update README with notebook instructions and project tree
