- Create notebooks/00_START_HERE.ipynb as the single entry point with plan
descriptions, audience guidance, and links to all 4 plans
- Add navigation footer cells to all 11 content notebooks with Next/Previous
links and back-link to Start Here
- Terminal notebooks (plan endings) offer cross-plan links to explore other plans
- Plan C dashboard gets explicit recommended reading order (Track A → B → C)
- Add test_start_here_exists_and_links_all_plans and
test_every_notebook_has_navigation_footer to test suite
- Skip navigation-only notebooks in code-cell and assessment tests
Plan D structures the material as a scientific argument chain:
- Experiment 1: Can the [[4,2,2]] code protect a magic state? (W=1.0, 12/12 errors)
- Experiment 2: How much magic survives noise? (scoring, parameter sweeps)
- Experiment 3: Can a ratchet learn to optimise? (monotonic improvement, transfer)
Each notebook follows Hypothesis → Claim → Experiment → Proof → Next Hypothesis.
Includes builder script, updated learning objectives, README, and compendium cross-ref.
