- content.Subject + Unit.subject, /api/home?subject=, tutor grounded in the chosen book
- 5 new books ingested; ~1150 hand-written questions, islands named by hand
- node_split: islands over 7 lessons split into parts of <=6 (lesson ids and progress kept)
- Lesson.figures hand-authored and visually checked for 653 lessons of the new books;
gen_lesson_figures got --subject and survives network errors
- seed files re-exported

Diagrams: 14 kinds drawn by the app (plane with constructed points, graphs with
computed roots/extrema/tangents, number lines with intervals, solids, charts,
tables, Venn, mapping, trees, fractions, grids, groups, clock). The catalog is
split by topic and only the matching sections go next to a question (200-1073
tokens instead of 1854). parse() repairs slips seen on 96 real book problems:
Persian digits in JSON numbers, 2*pi, // comments, bare items, Venn with
Persian set names. Measured: 45/48 valid on the second round, 0/8 on plain
arithmetic; visual review of 83: 64 right, 3 weak, 16 wrong.
Content: 82 new questions so no island has fewer than four; fill_lesson_texts
writes Unit.blurb (58) and Lesson.example/steps (590) from verified book
problems, never the lesson's own quiz problem. seed_content only fills empty
fields, so admin edits survive a deploy. Tedi unlocks at 500 xp.
