 ## Current Phase
-SHIP BUILD v12.0 — i18n (10 languages) + Africa tier (Session 12)
+SHIP BUILD v13.0 — The Slate (browse-first dashboard) + OAuth providers + Africa geo (Session 13)
+
+## Session 13 (2026-06-11) — SHIPPED
+
+### Phase 1 — Africa geo-restriction via CF-IPCountry
+
+The Session 12 Africa tier was visible to anyone on a Swahili locale
+(too narrow: most African users browse in English/French; too broad:
+Swahili speakers anywhere got the discount). Session 13 swaps the
+locale proxy for real Cloudflare IP geolocation.
+
+- **`web/middleware.ts`** — reads `cf-ipcountry` (uppercase),
+  stamps `x-vyndr-country` on the request alongside the locale header.
+  Empty string when traffic bypasses Cloudflare (local dev).
+- **`web/src/lib/locales.ts`** — `AFRICAN_COUNTRIES` set covering all
+  54 sovereign African nations (NG/KE/ZA/GH + sub-Saharan + MENA
+  overlap). `isAfricanCountry(code)` is case-insensitive and degrades
+  closed on empty/null inputs.
+- **`LocaleContext`** — extended with `country`/`inAfrica` fields;
+  new `useRegion()` hook for components that gate by geography.
+- **`Pricing.tsx`** — `inAfrica === false` filters the Africa tier
+  out of the render entirely. `inAfrica === true` puts it first.
+  Locale-based reorder removed.
+- **Pricing grid CSS** — desktop column count now tracks the visible
+  tier count via a `--pricing-cols` CSS custom property on the grid
+  root (3 outside Africa, 4 inside). Sidesteps a styled-jsx
+  limitation with attribute selectors inside `:global()`.
+
+### Phase 2 — OAuth: Google + Apple + X
+
+- **`AuthContext`** — added generic `signInWithProvider(provider)`
+  alongside the legacy `signInWithGoogle()` (kept as an alias so
+  existing callers don't break). Translates Supabase OAuth errors
+  into a flat `{ error: string }` so the UI can surface a friendly
+  inline message when a provider isn't configured.
+- **`login/page.tsx` + `signup/page.tsx`** — both pages now render
+  three OAuth buttons (Google, Apple, X). The `handleOAuth` helper
+  routes to `signInWithProvider` and shows an inline error when the
+  provider isn't configured ("apple login isn't available yet. Use
+  email or another method.").
+- **External configuration required** (operator action, not code):
+  - Supabase Auth → Providers → Apple: needs an Apple Developer
+    Service ID + private key
+  - Supabase Auth → Providers → Twitter: needs an X Developer OAuth 2.0
+    client
+  - Google should already work — if it doesn't, verify Supabase
+    Auth → URL Configuration → Site URL = https://vyndr.app and
+    Redirect URLs include `https://vyndr.app/**`, and that the Google
+    Cloud Console OAuth consent screen has the Supabase callback URL
+    in Authorized redirect URIs.
+
+### Phase 3 — The Slate (browse-first dashboard)
+
+Generalizes the Session 8 `/soccer` page pattern across every sport.
+
+- **`web/src/components/PropRow.tsx`** — single-prop UI with three
+  states (ungraded/grading/graded). Pure presentational — parent
+  owns the API call so there's one shared rate-limited grading queue.
+  Free-tier expansion shows blurred reasoning + Unlock CTA; paid tier
+  shows full reasoning + kill conditions. Exports `propRowKey()` for
+  stable Map keys.
+- **`web/src/components/GameCard.tsx`** — game header + expandable
+  prop list. Sport emoji prefix (🏀 NBA/WNBA, ⚾ MLB, ⚽ soccer),
+  sport-accented left border, formatted local game time, `+ N more`
+  expander when props > defaultVisible.
+- **`web/src/components/Slate.tsx`** — the orchestrator. Sport tabs
+  (ALL / NBA / WNBA / MLB / Soccer), sticky search input, group-by-game
+  pipeline, `gradedProps` Map, single-flight grading queue
+  (`gradingKey`). `Promise.allSettled` fan-out for the ALL tab so a
+  single sport failing doesn't blank the slate. `FETCH_URLS` is
+  null-aware — sports without an odds proxy yet (WNBA, MLB) render a
+  bottom-of-page "endpoint not configured yet" note rather than
+  spamming 404s.
+- **Search filter + manual-scan fallback** — sticky search filters
+  game cards by team name and prop rows by player/stat. Empty result
+  shows a CTA linking to `/scan?q=<query>` so users land on a
+  partially-filled scan form.
+- **`/dashboard`** — `<Slate />` mounted as the lead surface above
+  the existing Top Graded / Most Parlayed / Recent Reads sections.
+  Those sections stay as supplementary intelligence layers — not
+  removed.
+- **`Nav.tsx`** — "Scan" link removed from primary nav. The Slate is
+  the scan surface; `/scan` stays reachable from the slate's
+  empty-state CTA.
+
+### Tests added
+| Suite                                  | Tests |
+|----------------------------------------|-------|
+| `tests/unit/africaCountries.test.js`   | 6     |
+| **Session 13 total**                   | **6** |
+
+### Quality gates
+- `npm test`: **1311 / 1311 passing** (1305 + 6 new), 102 suites, 0 regressions
+- `web/npm run build`: clean — Slate page + components prerender
+- License audit: third-party deps remain permissive
+
+### Honest gaps (documented, not bugs)
+- I could not visually verify The Slate in a browser. Build/type
+  correctness is confirmed; "renders correctly with live odds data"
+  needs a deploy smoke test.
+- Google/Apple/X OAuth: button wiring is complete. Whether the
+  buttons actually authenticate depends on external dashboard
+  configuration (Supabase + Google Cloud Console + Apple Developer +
+  X Developer Portal). Apple and X are guaranteed to show the
+  "isn't available yet" inline error until configured.
+- WNBA + MLB don't have `/api/odds/*` proxies on the Next.js side
+  yet. The Slate degrades cleanly (footer note), but those tabs
+  return empty until the proxies exist. Session-14 work.
+- Africa tier still can't be SOLD even when geo gates open it —
+  the Stripe price + the DB CHECK migration remain outstanding from
+  Session 12.
+
+### Coolify env (Session 13 additions)
+None. CF-IPCountry is set by Cloudflare automatically; no env-var
+change required.
