Feature: Group Classes

Overview

Students enrol in a group class — an offering of kind group_class — as a commitment for the year. Enrolment is capacity-enforced and billed full-term upfront. Registration reuses the same flow as private lessons (intake questions + policy acceptance + payment).

Data Model — {prefix}us_group_enrollments

Column	Type	Notes
id	BIGINT UNSIGNED	Primary key
offering_id	BIGINT UNSIGNED	FK → us_offerings.id (kind = group_class)
student_id	BIGINT UNSIGNED	WordPress user ID
instructor_id	BIGINT UNSIGNED	WordPress user ID (denormalised from the offering)
status	VARCHAR(20)	active / cancelled / completed
payment_id	BIGINT UNSIGNED	Nullable FK → us_payments.id
enrolled_at	DATETIME	Insertion time

Enrolment Flow

1. Student opens a group class from the offering catalog.
2. Student answers the offering's questions (GET /offerings/{id}/questions).
3. Student accepts the current published policy versions (GET /policies) — required to continue.
4. Full-term payment is taken per the student's billing method (card by default; pending for e-transfer; skipped for comp). See payments.md.
5. POST /enrollments creates the enrolment (status = active), records answers and policy acceptances, and links the payment — but only if the offering's capacity has not been reached.
6. On successful payment (or comp) a receipt is emailed.

Capacity is enforced at enrolment time by counting active rows for the offering; a class at capacity rejects further enrolments.

REST API

Method	Endpoint	Permission
GET	/wp-json/us-scheduler/v1/enrollments	Any logged-in user
POST	/wp-json/us-scheduler/v1/enrollments	book_lesson

POST /enrollments body: offering_id, answers[] (question_id → value), accepted_policy_version_ids[], and payment data (see payments.md).

GET /enrollments returns the caller's own enrolments, or all enrolments for the instructor's group classes if the caller has view_own_lessons on those offerings.
