classes-logic.ts: effectiveCapacity (session override > class > unlimited), computeSignupStatus (registered vs waitlisted), sessionTiming, canSignUp eligibility, pickPromotion (earliest waitlisted when a seat frees). Dependency-free, 10 unit tests (suite 372 -> 382). validations.ts: class/session/signup/attendance schemas. payment_link is a generic http(s) link only (empty -> null); capacity is a positive int; no live payment integration.
