The download path now resolves the files row via SupabaseServiceRoleClient (to
sidestep the cabinet_memberships RLS recursion); the test must mock it like the
upload test does. Test-only.

Pre-merge smoke caught a second issue: the source_file_id download path read `files`
as-the-user, tripping a PRE-EXISTING broken RLS policy on cabinet_memberships
(42P17 infinite recursion). Authz is already enforced (template fetch + source
visibility), and source_file_id is the template's own file, so resolve the row via
service role (documented exception, same as the catalogue lookup). Flagged the
cabinet_memberships RLS recursion separately as infra bug E8.

Pre-merge live smoke on .94 caught 'Bucket not found': the upload wrote to a
per-institute bucket cc.institutes.<id>.private that isn't provisioned on dev.
Use the shared SOURCE_BUCKET_FALLBACK (cc.users); institute is namespaced in the
storage path + enforced by the files-row RLS. Per-institute buckets are a future
multi-tenant concern. Catalogue path + cross-institute 404 already verified green.

Recovered from cc-worker WIP that was left uncommitted in the dev-centre clone
(card t_0055b89b). Multipart source_pdf upload at create -> source_file_id;
source-pdf download endpoint resolves from exam_id (catalogue) or source_file_id.
NOT yet human-reviewed/merged; preserving + verifying so it isn't clobbered.

Backend follow-on to migration 73:
- schemas: ResponseAreaPayload.kind extended to response|context|question_number|
mark_area|reference|furniture + context_type; QuestionPayload gains bounds+page.
- PUT serialization persists Part bounds/page and region context_type.
- Neo4j projection only emits Region nodes for response/context regions; the
metadata kinds (question_number/mark_area/reference/furniture) are physical-layer
only and stay out of cc.public.exams.
- Unit test: new kinds + Part geometry + context_type round-trip.

The previous commit added apikey to _create_base_client headers, but supabase-py
already sets apikey from the key arg → two apikey headers → Kong rejected every
as-user call with 401 'Duplicate API key found' (exam API 502'd on auth). Revert
to Authorization-only; fix the two header unit tests to assert the real contract
(apikey via the key arg; options.headers carries only the user Authorization).
Co-Authored-By: Claude Opus 4.8 <[email protected]>
- client.py: set apikey explicitly in _create_base_client headers (Kong needs it
on every request; for per-user clients apikey stays anon while Authorization
carries the user JWT). Fixes the 2 stale header unit tests that asserted apikey
in options.headers, and is robust against supabase-py default-header changes.
- test_dev_stack: exact == seed counts → >= baselines. The greenfield seed sets a
floor; additive exam-marker fixtures (S4-4 cohort) legitimately push live .94
counts above the old snapshot. >= still catches a broken/missing seed.

Brings in the full exam-marker HTTP API on /api/exam (as-user RLS, E1/E2 fixes):
- S4-5 template CRUD (hybrid PUT + PATCH)
- S4-6 batches/scans/marks/results/CSV (A7), roster-from-class_students
- S4-7 Neo4j projection on save + neo4j-sync
Also fixes pre-existing E7: storage.py brace-doubling crash (all uploads).
Verified: 35 unit tests; live as-user RLS smoke .94 (templates 17/17, batches
20/20); live graph smoke .94+.209 (projection 17/17). Reviewed; data-loss guard
added (409 on destructive template PUT once marks recorded).

PUT full-replace deletes exam_questions, and mark_entries.question_id cascades
ON DELETE — so re-saving the setup canvas after marking began would silently
wipe recorded marks. Guard: 409 if any mark_entry exists for the template's
batches. Mark-scheme edits (PATCH /questions/{id}) are unaffected.

modules/database/services/exam_projection.py projects a saved template into
cc.public.exams: ExamPaper -> Question/Part -> Region + Part-[:ASSESSES]->
SpecPoint, joined by shared UUIDs (exam_questions.id, exam_response_areas.id,
exam_code, spec_code). Full re-sync per exam_code (idempotent). Reads via
service role + writes via system Neo4j driver (R3.5.1 documented graph-writer).
Wiring (R3.5.4/R5.3):
- PUT /templates/{id} enqueues project_template_safe via BackgroundTasks
(swallows failures so a graph hiccup never fails the canvas save).
- POST /templates/{id}/neo4j-sync — manual trigger, as-user auth + owner check,
runs synchronously and returns projection counts.
Unit tests: projection scheduled on PUT; neo4j-sync owner/403/404.

Pre-existing bug (E7): the whole file had doubled braces, so every dict literal
was a set containing a dict -> 'unhashable type: dict' at runtime, and log
f-strings printed literal {braces}. This broke StorageManager.upload_file /
list_bucket_contents / create_bucket / bucket-init for ALL callers (incl.
files.py uploads), not just exam scans. Mechanical de-double; no logic change.

A roster student starts 'absent' and a direct mark would otherwise still show a
blank total. Now total is blank only when absent with no marks; recording a mark
advances the submission out of absent/unmatched to 'marking'.

Adds routers/exam/batches.py (mounted alongside templates under /api/exam):
- POST/GET /batches — batch creation seeds the cohort from class_students AS
THE USER (cs_read requires caller teaches/admins the class); each active
enrollee becomes a student_submissions row (status='absent') so no student
is ever dropped from results (A7). Display names denormalised via a
documented service-role profiles read (deny-all as-user, E4).
- GET /batches/{id}/queue — submissions + per-submission mark counts + progress.
- GET /batches/{id}/results + /csv — every roster student incl. absent (blank
marks/total); CSV row always present (A7 baked into the contract).
- PUT /marks/{id} — upsert; batch_id derived server-side from the submission
(client never supplies the RLS scoping key).
- POST /batches/{id}/scans — E3 guards: MIME check, hard size ceiling (chunked
read), %PDF magic-byte sniff; owner-only; stores via service-role storage;
manual/ordered matching (QR-decode is a follow-on, no QR fixtures yet).
Unit tests cover batch/roster-seed/list, queue, results+CSV A7, mark upsert
round-trip, and all scan guards + owner check.

S4-5: new routers/exam/ package mounted at /api/exam (R5.1/E5, not under
/database/). Template CRUD with hybrid persistence (R5.2):
- POST/GET/GET{id}/PUT{id}/DELETE{id} /templates + PATCH /questions/{qid}
- Calls Supabase AS THE USER via SupabaseAnonClient.for_user (E1 fix), so the
RLS in 72-exam-marker.sql is enforced; no service-role for user-facing ops.
- Institute resolved/validated via the user_institute_ids() SECURITY DEFINER
RPC (institute_memberships is deny-all as-user per E4); client-supplied
institute_id is validated, never trusted (R5.5).
- Ownership pre-checked before writes (E2); out-of-scope ids read back as 404
under RLS (IDOR-safe). Soft-delete archives, never hard-deletes.
- PUT full-replace preserves client UUIDs as Neo4j join keys (spec §2).
- eb_exams.exam_code denormalised via a documented service-role catalogue
lookup (eb_exams is shared reference data, deny-all as-user per E4).
Unit tests cover auth, CRUD, ownership/IDOR, institute validation, soft-delete.

Adds the real AQA GCSE Physics 8463 specification and the AQA-PHYS-8463-1H-22-JUN
exam paper (Paper 1, Higher, June 2022, QP) to seed_curriculum.py, with storage_loc
pointing at the uploaded PDF in the cc.examboards bucket. spec_code AQA-PHYS-8463
matches the cc.public.exams Specification node (S4-1).
Applied + verified on dev .94: eb_specifications + eb_exams rows present; the real PDF
(3,963,384 bytes) is uploaded to cc.examboards/aqa/physics/8463/AQA-PHYS-8463-1H-22-JUN.pdf
and retrievable (HTTP 200, exact byte match). seed run populated the empty catalogue
(7 specs / 16 exams / 42 Neo4j topics).
NOTE: the PDF upload is a one-time ops step (curl from the host to the Storage API) —
the container can't reach the host file. A reproducible fixture-upload step is a follow-up.

- modules/database/schemas/nodes/exams/exam_nodes.py: neontology node classes for
ExamBoard/Specification/SpecPoint/ExamPaper/Question/Part/Region (uuid_string joins
to Supabase exam_questions.id / exam_response_areas.id / eb_exams.exam_code).
- run/initialization/init_exam_graph.py: idempotent init — creates the shared public
cc.public.exams database, 10 uniqueness constraints, and seeds AQA + AQA-PHYS-8463
(GCSE Physics) with its 8 top-level topic SpecPoints.
Applied + verified on dev Neo4j (192.168.0.209, enterprise): db online, 10 constraints,
AQA-[:PUBLISHES]->AQA-PHYS-8463-[:HAS_SPEC_POINT]->8 points. Full sub-point catalogue is
a later data task. spec_code AQA-PHYS-8463 must match the eb_exams seed (S4-3).

Adds seed_cohort_9p_ph1.py — creates N student accounts (default 10) and enrols
them all into one class (Greenfield Year 9 Physics 9P/Ph1) so there is a real
cohort to mark. The canonical timetable seeds enrol one student per year-band,
leaving every class with <=1 student.
Uses the same paths as the canonical seeds (auth admin create user, profiles +
institute_memberships upsert, POST /database/timetable/classes/{id}/students as
school admin). Idempotent. Self-contained HTTP (runs inside the ccapi container).
Verified on dev .94: 10 created + enrolled, 0 errors; 9P/Ph1 roster = 11;
physics teacher sees all 11 under as-user RLS.

The _get_profile select list omitted school_id, causing
/me/bootstrap to always return null for that field even after
the column was populated.
