Two shapes, because a plan is asked to do two different things. Papers
are rehearsal: each block is drawn to the ABP's published weights, so
sitting one says something about how you would do on the day. Domains
are study: the board's twenty-four content areas in its own order and
carrying its own titles, each given the share of the plan the board
gives it on the exam.
Both were written, then run against the real bank, which found two bugs
a unit test on a clean fixture would not have. Domains 19 and 20 —
nephrology and genitourinary — both map to our "Nephrology & Urology",
so a question sat in two pools and was dealt twice; the deal now keeps a
record of what has gone. And chunking every question a domain has into
blocks of forty gave preventive care six blocks and the plan a hundred
and sixty, which is not a plan: blocks are shared out by weight, with at
least one per domain so nothing the board examines is left out.
Built on the live bank alongside what was already there: Boards: Full
Papers (12 × 40) and Boards: By Content Domain (27 blocks, 1069
questions). Nothing existing was touched.
Psychosocial Issues and Child Abuse and Neglect — 6% of the paper
between them — had no category of ours at all, so they could contribute
nothing. Both now exist, with sub-topics named from the board's own
subdomains, and all 24 domains map to categories.

Thirteen plans were seeded with an API to serve them and nothing that called it,
so the whole feature existed only in the database. Two pages and the editing
endpoints it was missing.
/study-plans lists the plans with progress stated in blocks — "3 of 6 blocks"
is something you can act on, where "50%" only tells you how you feel about it.
/study-plans/:id is one plan: each block shows Articles, then Sessions, in that
order, because that is the order the block is meant to be done in.
Reading is now part of a block (migration f4a5b6c7d8e9). "Mark as read" is the
learner's own claim and reversible — someone who ticks the wrong row should be
able to fix it without an educator, and progress nobody can correct stops being
trusted and then stops being used. It is a separate table from `article_views`
on purpose: opening an article is not the same claim as having finished with it.
A draft article attached to a block is listed for the educator who can open it
and left out for everyone else, rather than offered as a dead link.
Editing is inline on the learner's own page rather than a separate builder, so
the thing being changed and the thing a learner sees are the same object.
Moderators create (as a draft — an empty plan is not something to put in front
of anyone), rename, publish, delete; add, rename, reorder and remove blocks;
move questions between blocks of one plan; attach reading found by searching
rather than by id.
Two places where the obvious implementation leaves the data wrong, both tested:
deleting a block out of the middle shuffles the survivors down, or the next
insert collides with a position nothing occupies; and reordering parks every row
outside the range before writing the real positions, because (plan_id, position)
is unique and the first move would otherwise collide with a position still held.
A partial order is refused rather than half-applied.

The PREP sets were loose admin-generated quizzes. They are now study plans: one
per year, split into blocks of 50 numbered "Block 1", "Block 2", plus a
"PREP Mixed" plan of 300 drawn at random across every year. 12 plans, 2,821
questions, applied to production.
Block membership is snapshotted rather than stored as a filter — a plan you are
part-way through must not reshuffle between visits. Re-running the seeder updates
years whose questions changed and leaves the mixed draw alone unless --reshuffle.
Starting a block reuses the learner's existing quiz for it; without that,
reopening a block would create a duplicate test each time and scatter the
attempts across them. Only questions the learner may see are included.
Tests: 113 backend green.
