get_sponsorship_details, get_user_sponsorship_inquiries, create_sponsorship_payment_link and withdraw_sponsorship_enquiry each hand-built a dict and raised a bare frappe.throw, so every refusal came back as a generic 417 with the copy inline at the call site. The three per-enquiry endpoints now go through SponsorshipService, which reads the enquiry and its event as plain properties over get_cached_doc and owns the permission checks. The list endpoint stays a module-level function — a list query is not one enquiry, and a class with a single method is ceremony. Responses are pydantic models declared to match the wire byte for byte: same keys, same order, same date rendering. Errors are five named classes carrying their own status and copy — three 403s (view, pay, withdraw) and two 409s (already paid, already withdrawn). frappe.DoesNotExistError is left alone on an unknown enquiry; it already says the right thing with the right status. The two per-row title lookups in the list endpoint are batched into maps. Buzz Event autonames to integers on some sites while Link fields arrive as strings, so those map keys need an explicit str() cast — the get_value calls this replaces were coercing in SQL. No endpoint renamed and no payload reshaped, so the dashboard is untouched. Both read endpoints were diffed against a copy of the pre-change module and came out identical, then re-checked over HTTP for key order, date format and the 409 reaching err.messages[0].

get_payment_link_for_booking and get_payment_link_for_sponsorship were whitelisted, but their only callers live inside buzz/api — they are service functions, not endpoints, and being remotely callable let a client name its own amount source. The decorators go; the functions stay where they are, since buzz/payments.py already is the payments service layer and doctype controllers import from it. Two more things in the module were dead rather than merely unused. get_payment_gateway_for_event had no caller anywhere. And the "fallback to legacy field" branch in get_payment_gateways_for_event read Buzz Event.payment_gateway, a field the doctype no longer has, so get_cached_value returned None and the branch always produced []. Deleting both leaves behaviour unchanged. test_payments covers the one endpoint the domain has. It is thin enough that a service layer would be an empty hop, so payments/ gets no services.py and no schemas.py — get_event_payment_gateways returns a list of strings, and modelling that would be fiction.

setUpClass picked the first existing Payment Gateway record, which works on a bench that has one configured and raises IndexError on CI, where none exist. The test now creates its own gateway per test, inside the transaction that tearDown rolls back. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

SponsorshipService— enquiry and event as plain properties overget_cached_doc, permission checks in one place.
