Creates the shared, public exam database, its uniqueness constraints, and seeds the AQA exam board
|
||||
+ the 6 current test specifications (GCSE & A-level Physics/Chemistry/Biology) with their top-level
|
||||
topic SpecPoints (44 in total). Idempotent (CREATE DATABASE IF NOT EXISTS / CREATE CONSTRAINT IF NOT
|
||||
EXISTS / MERGE).
|

|

Run inside the ccapi container:
|
||||
python3 -c "from run.initialization.init_exam_graph import init; import json; print(json.dumps(init()))"
|
||||
|
||||
NOTE: the 8 SpecPoints seeded here are the real AQA GCSE Physics *top-level* topics. The full
|
||||
sub-point breakdown (e.g. 4.1.1.1 ...) is a later data-population task (sourceable from the AQA
|
||||
spec PDF via Docling). spec_code AQA-PHYS-8463 is the standalone GCSE Physics code that matches
|
||||
"AQA Physics Paper 1H"; the eb_exams/eb_specifications seed (card S4-3) must use the same code.
|
||||
NOTE: only *top-level* topics are seeded (the granularity a teacher plans against). The full sub-point
|
||||
breakdown (e.g. 4.1.1.1 ...) is a later data-population task (sourceable from the AQA spec PDF via
|
||||
Docling). Seeding all 6 specs means a template's spec_ref finds a matching SpecPoint so
|
||||
(:Part)-[:ASSESSES]->(:SpecPoint) fires beyond GCSE Physics; spec_code (e.g. AQA-PHYS-8463) must match
|
||||
the eb_exams/eb_specifications seed (card S4-3) and the app's deriveSpecCode.
