db/gradebook-code: semester-aware gradebook + curve + drop-lowest (epic slice PR3) by AndresL230 · Pull Request #274 · SaplingLearn/Sapling

AndresL230 · 2026-06-24T19:42:46Z

Gradebook slice (migration 0021, + curve/drop-lowest #266). Enrollment-keyed gradebook; per-semester + cumulative GPA; bell-curve (raw vs curved) + drop-lowest; decrypt_numeric on 🔒 points; new PATCH /courses/{id}/curve + GET /gpa; hand-computed GPA fixture. Green; ruff clean.

Plan: docs/superpowers/plans/2026-06-24-db-gradebook-code.md.

Integration note: touches models/__init__.py + tests/test_response_decrypt_boundary.py (also edited by db/identity-code — small additive conflict). Largest slice — suggest merging last.
