Pure signupFormEligibility (manager override bypasses) + 4 tests.
signUpForClass now: classes.manage override + sign-up-on-behalf
(targetMemberId), and a hard form gate -- if the class has a
required_form_id the member must have a form_submissions row on file
(checked via service client, since a class manager need not hold
forms.manage). create/updateClass validate the form is in-space and
published. listUpcomingSessions exposes required_form {title,url,
satisfied}. Manage UI: published-form picker on create/edit + a 'requires
form' badge. Member UI: shows the requirement, links to the form, and
replaces Sign up with 'Complete required form' until it is on file.
Mirrors the equipment cert-gate pattern.
classes.ts: class/session CRUD (classes.manage; delete refused once
sessions/signups exist, archive instead), member signUpForClass /
cancelMySignup as validated service-client writes enforcing eligibility,
capacity vs waitlist, de-dupe and earliest-waitlist promotion on cancel,
listUpcomingSessions (service-client counts so members see spots-left
without seeing who signed up), instructor markAttendance and
completeSession. completeSession awards a class's certification via the
normal grantCertification path, so it only issues when the acting
instructor also holds certifications.grant; otherwise completion still
succeeds and reports certificatesSkipped. classes-guard mirrors the
forms/certifications guards. Barrel + API_REFERENCE updated.
