Bloom's Taxonomy Distribution

The corpus shows a healthy pyramidal distribution with the majority of steps at Apply (50.6%), a strong Understand base (19.1%), and adequate higher-order representation at Analyze (7.9%), Evaluate (6.7%), and Create (9.0%). Both has_min_understand_steps and has_min_analyze_steps pass. No Bloom gap proposals were generated.

Systemic Observations

Checkpoint gap in Part 2: A systemic pattern accounts for the majority of the corpus decline: 22 files across Part 2 and side quests lost their checkpoint sections, causing checkpoint_quality scores to drop to 0.0. This drove a uniform −2.00 delta across these pages (baseline ~7.8–8.9 → latest 5.45–6.93). The root cause appears to be a content edit pass that removed ## :white_check_mark: Checkpoint sections from advanced and side-quest pages.

Part 2 vs Part 1 gap: Part 2 mean (6.76) trails Part 1 mean (8.03) by 1.27 points, driven almost entirely by the missing-checkpoint pattern. Restoring checkpoints on the affected Part 2 pages would close most of this gap.

Active learning density: Multiple pages across both parts show activity density below the 3.0 ideal, with several Part 2 pages at 0.75–1.12 (vs. ideal ≥3.0), indicating low code-block and checklist density relative to word count.
