Previously the publicTicket comparison block ran whenever a Member record
existed, which surfaced "$0 saved" for cancelled/suspended/guest accounts.
Use the canonical hasMemberAccess helper so only active/pending_payment
members see the savings comparison.
When a series requires a pass and doesn't allow drop-ins, the
per-event availability endpoint returned a generic "No tickets
available" reason, leaving the UI to render an "Event Sold Out"
block for guests (logged-in users short-circuit via
check-series-access first).
Detect the gate server-side and return
{available:false, reason:"series_pass_required", requiresSeriesPass:true,
series:{id,title,slug}} so EventTicketPurchase's existing
requiresSeriesPass branch renders a pass-required CTA with a link to
the series page. The register and purchase handlers already enforce
the gate server-side; this is a messaging fix only.
Pre-launch P0 fixes surfaced by docs/specs/events-functional-test-matrix.md
(Findings 1, 2, 3).
1. Series-pass bypass (Finding 1 / matrix S1 P3): register.post.js now
loads the linked Series when tickets.requiresSeriesTicket is set and
rejects drop-in registration unless series.allowIndividualEventTickets
is true or the user has a valid pass. Data-integrity 500 if the
referenced series is missing.
2. Hidden-event leak (Finding 2 / matrix E11): extract loadPublicEvent
into server/utils/loadEvent.js. All five public event endpoints
([id].get, register, tickets/available, tickets/reserve,
tickets/purchase) now go through the helper, which 404s when
isVisible === false and the requester is not an admin. Admin detection
uses a new non-throwing getOptionalMember() in server/utils/auth.js
(extracted from the pattern already inlined in api/auth/status.get.js).
3. Deadline enforcement + legacy pricing retirement (Finding 3 / matrix
E8): register.post.js and tickets/reserve.post.js delegate gating to
validateTicketPurchase (which already covers deadline, cancelled,
started, members-only, sold-out, and already-registered);
tickets/available.get.js gets an explicit registrationDeadline check.
Legacy pricing.paymentRequired 402 branch removed from register.post.js.
