- Prisma: Zone (postal-code list or radius), Rate (zone- or distance-band
keyed), GeocodeCache (permanent address->lat/lng cache per
IMPLEMENTATION_PLAN.md §9), Location.shopifyLocationId (maps to
Shopify's own Location resource for inventory checks), Booking.zoneId
(needed for per-zone delivery-density counts, not just per-location).
- app/lib/geo.ts: pure haversine distance + postal-code matching, unit
tested against known city-to-city distances.
- app/services/zones.server.ts: geocoding (Google Maps Geocoding API,
cached — never re-geocodes the same address twice), zone eligibility,
nearest-location auto-assignment ranked by distance, delivery-density
threshold checks (a sparse zone doesn't unlock until minOrders bookings
have already routed through it), and inventory-based location exclusion
via Shopify's InventoryLevel API (locations without a mapped
shopifyLocationId are left in rather than false-negative excluded).
- app/services/rates.server.ts: pure rate resolution by zone or distance
band, cheapest-match-wins when bands overlap.
- apps.scheduling.availability.tsx: LOCAL_DELIVERY requests with a
postalCode/address now auto-assign to the nearest eligible,
density-qualified zone/location instead of the shop's default location;
response includes the matched rate. Also fixed a real gap left over from
Phase 4: this route never actually read Booking counts into
getAvailability's `consumed` map, so capacity always showed as fully
available regardless of existing bookings — now it does.
- extensions/datetime-widget: LOCAL_DELIVERY now asks for a postal code
before showing dates; PICKUP shows a Google Maps pin for the location
(both gated on an optional Maps API key — a block setting in the theme
editor, since it needs to be public/client-side, not an app secret);
confirmation display and cart attributes (dd_zone_id, dd_rate_label)
carry the resolved zone/rate through to checkout.
- extensions/delivery-customization: now appends the resolved rate to the
relabeled delivery option ("Local delivery — Aug 25 ($5.99)") when one's
configured — real Cart Transform-based fee *charging* stays deferred to
v2 per IMPLEMENTATION_PLAN.md §5.4, this is display-only.
- Admin: /app/zones and /app/rates (Polaris CRUD, mirroring Phase 1's
patterns), plus shopifyLocationId and auto-geocode-on-save added to the
location edit form.
Fixed one real bug caught only by `npm run build` (not tsc/vitest, which
both passed clean): app.rates._index.tsx's component called
formatPriceLabel from rates.server.ts, and Remix correctly refuses to
bundle anything imported from a .server.ts path for the client. Moved the
pure (no I/O, no Prisma) formatter to app/lib/currency.ts.
Verified: lint, typecheck, 86 unit tests (+21 new: geo, zones, rates,
delivery-customization's rate-label case with a real WASM fixture run),
16 integration tests against live Postgres (+8 new: geocode caching,
postal/radius zone matching, nearest-first ranking, density thresholds),
both builds, and a live script exercising the full
zone-match -> density-check -> rate-resolve -> availability pipeline
together against the Postgres container.

Implements the "heart" of the app per IMPLEMENTATION_PLAN.md §6 Phase 2,
no UI yet by design:
- app/lib/time.ts: Luxon-based wall-clock helpers. slotDateTime() builds a
slot's instant from calendar-date + minutes-from-midnight by setting
hour/minute fields directly rather than adding an elapsed-time duration
to midnight — the latter is wrong by exactly one hour for any wall-clock
time on a spring-forward day, since a real elapsed-time addition crosses
the lost hour. Also detects and rejects wall-clock times that don't exist
in a spring-forward gap (Luxon silently rolls these forward instead of
invalidating them, so this required an explicit post-set field check).
- app/services/scheduling.server.ts: getAvailability(), a pure function
(no DB/Shopify calls — every input injected, including `now`) that
applies slot templates, date overrides, blackout dates, cutoff/lead-time,
and capacity to produce the bookable slots per date. Excludes unavailable
slots entirely rather than flagging them, per PRODUCT_STRATEGY.md §2.
- app/services/capacity.server.ts: remainingCapacity()/hasCapacity() — kept
as pure functions over an injected `consumed` count so this doesn't need
to change once Phase 4 adds real Booking/SlotHold-backed consumption.
41 unit tests total (up from 8), including DST regression tests that would
fail against a naive "midnight + elapsed minutes" implementation, an
ambiguous-time (fall-back) case, a nonexistent-time (spring-forward gap)
case, and a getAvailability run across the actual 2024 spring-forward date
verifying both the UTC offset change and that wall-clock hours stay correct
on both sides of it.

Bootstraps from Shopify's official shopify-app-template-remix (cloned
directly rather than via `shopify app init`, which requires an interactive
Partner login unavailable in this session):
- Prisma (SQLite dev / Postgres-ready) with baseline Session model + migration
- Vitest configured for unit tests, Playwright configured for E2E
- Redis client + BullMQ worker skeleton (app/lib/redis.server.ts, jobs/worker.ts)
- shopify.app.toml: minimal scopes, GDPR + orders webhooks wired (stub handlers),
app proxy config for the future storefront widget
- Stripped template-repo-only meta files (CLA, issue templates, demo product
page) and replaced CI with a lint+typecheck+test workflow
- Bumped @shopify/shopify-app-session-storage-prisma to resolve a duplicate
@shopify/shopify-api install that broke typecheck
- Dropped the Jest-only ESLint config (template default) since the project
standardizes on Vitest per IMPLEMENTATION_PLAN.md
Verified: npm install, lint, typecheck, unit tests, prisma migrate dev, and
npm run build all pass on Node 22 LTS.
