Multi-pin pickup selection (study §3.4) — previously a standalone unused endpoint + TODO comments: - app/services/pickup-locations.server.ts: pure filterPickupLocationIds + I/O resolvePickupLocations (active + has a PICKUP slot template + ProductRule allowedLocationIds + inventory exclusion). - resolveAvailabilityRequest returns pickupLocations[] on method=PICKUP and defaults the active location to the first eligible pickup point. - apps.scheduling.locations.tsx refactored onto the shared resolver (was a second copy of the logic). - Storefront widget: pickup-location chooser (name + address, optional multi-pin Google map) when >1 eligible point and none block-configured; picking one re-requests availability for that location. New styles + widget.choose_pickup_location locale (en + fr). - Checkout extension Checkout.jsx: same chooser before the date list. - tests/unit/pickup-locations.test.ts (5 cases); suite 161 green. checkout-datetime follow-up fixes from the 808a3b7 review: - typescript devDep ^7.0.2 -> ^5.6.3 (there is no typescript@7 on npm). - Deleted dead shopify.d.ts (Preact-global shim, unused after the React rewrite) and dropped it from tsconfig include. Also stages the CLI-written `uid` lines in the checkout-datetime and payment-customization extension tomls. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
payment-customization
Shopify Function (cart.payment-methods.transform.run) that hides
cash-on-delivery / pay-in-store payment methods when the shopper's chosen
fulfillment method is SHIPPING (study §5.2 parity).
Pure decision logic lives in src/evaluate.js and is unit-tested at the
repo root (tests/unit/payment-customization.test.ts) with plain Vitest —
no WASM build needed for that.
Before first build / deploy
schema.graphql and generated/ are not committed (they're produced
by codegen and gitignored, same as the other Function extensions). Run:
npm --prefix extensions/payment-customization run typegen
to pull the API schema and regenerate generated/api.ts, then
shopify app deploy picks it up. The extension also needs the
write_payment_customizations scope, which shopify.app.toml already
requests, and the merchant must activate it under
Settings → Payments → Payment method customizations in the admin.
