+<objective>
+Migrate the setups visibility model from boolean isPublic to three-tier visibility (private/link/public), add shares table to schema, and update all services, routes, schemas, and client code that reference isPublic.
+
+Purpose: This is the foundational schema change required by all other plans. Every service, route, and component that references isPublic must be updated atomically to prevent broken queries.
+
+Output: Updated schema with visibility column and shares table, migrated data, updated services/routes/schemas/hooks/components.

+# Plan 32-01 Summary: Schema Migration (isPublic -> visibility)
+
+**Status:** Complete
+**Commit:** edc9793
+
+## What was done
+
+1. **Schema changes** (`src/db/schema.ts`):
+   - Replaced `isPublic: boolean` with `visibility: text` (default "private") on setups table
+   - Added `shares` table with columns: id, setupId, token, permission, expiresAt, userId, createdAt, revokedAt
+   - Removed `boolean` import from drizzle-orm/pg-core
+
+2. **Migration** (`drizzle-pg/0005_true_green_goblin.sql`):
+   - Creates shares table with FK constraints
+   - Adds visibility column with data migration (`UPDATE setups SET visibility = 'public' WHERE is_public = true`)
+   - Drops is_public column
+
+3. **Full-stack isPublic -> visibility replacement** across 16 files:
+   - `src/shared/schemas.ts`: `z.enum(["private", "link", "public"])` replaces `z.boolean()`
+   - `src/server/services/setup.service.ts`: createSetup, getAllSetups, updateSetup
+   - `src/server/services/discovery.service.ts`: `eq(setups.visibility, "public")`
+   - `src/server/services/profile.service.ts`: Two occurrences updated
+   - `src/server/routes/account.ts`: Delete account reassignment query
+   - `src/client/hooks/useSetups.ts`: Types and mutation signatures
+   - `src/client/components/SetupCard.tsx`: Visibility badge (public=green, link=blue)
+   - `src/client/components/SetupsView.tsx`: Passes visibility prop
+   - `src/client/routes/setups/$setupId.tsx`: Temporary visibility badge with lock/link/globe icons
+   - `src/db/dev-seed.ts` and `src/db/dev-seed-data.ts`: Seed data updated
+
+4. **Tests updated** across 4 test files (46 tests pass):
+   - `tests/services/profile.service.test.ts`
+   - `tests/services/discovery.service.test.ts`
+   - `tests/routes/discovery.test.ts`
+   - `tests/routes/profiles.test.ts`
+   - `tests/helpers/db.ts`: Added shares to truncation list
+
+## Verification
+
+- `bun run lint`: Passes (0 errors)
+- All affected tests pass (46/46)
+- Zero isPublic/is_public references in src/ (except unrelated `isPublicRoute` in __root.tsx)
+- Zero isPublic references in tests/

+
+<objective>
+Create the share link service and API routes for managing setup share links — creating links with configurable expiration, listing active links, revoking links, and validating share tokens.
+
+Purpose: This is the backend for the share modal UI (Plan 03) and the shared setup viewer (Plan 04). Implements D-04 through D-12 share link mechanics.
+
+Output: New share service, API routes, and comprehensive tests.

+    - deactivateShareLinks: sets revokedAt on all non-manually-revoked links for a setup

+  </behavior>
+  <action>
+**Add share Zod schemas to `src/shared/schemas.ts`:**
+```typescript
+export const createShareLinkSchema = z.object({
+  expiresInDays: z.union([z.literal(7), z.literal(14), z.literal(30), z.null()]).default(14),
+});
+```
+
+**Create `src/server/services/share.service.ts`** following existing service patterns (db as first param, no HTTP awareness):
+
+```typescript
+import { randomBytes } from "node:crypto";
+import { and, eq, isNull, sql } from "drizzle-orm";
+import type { db as prodDb } from "../../db/index.ts";
+import { shares, setups } from "../../db/schema.ts";
+
+type Db = typeof prodDb;
+
+export async function createShareLink(
+  db: Db,
+  userId: number,
+  setupId: number,
+  options: { expiresInDays: number | null },
+) { ... }
+```
+
+Functions to implement:
+- `createShareLink(db, userId, setupId, { expiresInDays })`:
+  1. Verify setup belongs to userId
+  2. Generate token: `randomBytes(16).toString("base64url")` (22 chars, URL-safe, 128 bits — per D-04)
+  3. Calculate expiresAt: `new Date(Date.now() + days * 86400000)` or null (per D-07)
+  4. Insert into shares table with permission='read' (per D-09)
+  5. Return the created share row
+
+- `getShareLinks(db, userId, setupId)`:
+  1. Verify setup belongs to userId
+  2. Return all shares for setupId ordered by createdAt desc (per D-05, D-08)
+
+- `revokeShareLink(db, userId, shareId)`:
+  1. Join shares with setups to verify ownership
+  2. Set revokedAt = new Date() (per D-08)
+  3. Return updated share
+
+- `validateShareToken(db, token)`:
+  1. Find share by token where revokedAt IS NULL
+  2. Check expiresAt IS NULL OR expiresAt > NOW()
+  3. Return { setupId, permission } or null
+
+- `deactivateShareLinks(db, setupId)`:
+  1. Set revokedAt on all shares where revokedAt IS NULL (per D-03)
+  2. Mark these with a sentinel: use current timestamp (distinguishable from manual revokes by exact timestamp match)
+
+- `reactivateShareLinks(db, setupId)`:
+  1. Clear revokedAt on all shares that were deactivated (where revokedAt IS NOT NULL and the share was not manually revoked before deactivation)
+  2. Simple approach per D-03: clear revokedAt on ALL non-expired shares for the setup. This reactivates everything, including manually revoked links — acceptable UX since user explicitly chose to re-enable sharing.
+
+**Update `src/server/services/setup.service.ts` `updateSetup` function:**
+- After updating visibility, check transitions:
+  - If new visibility is "private" and old was not: call `deactivateShareLinks(db, setupId)`
+  - If new visibility is "link" or "public" and old was "private": call `reactivateShareLinks(db, setupId)`
+- To detect the transition, read the current setup before update.
+
+**Create `tests/services/share.service.test.ts`:**
+- Use `createTestDb()` from tests/helpers/db.ts
+- Seed a user, category, and setup
+- Test all behaviors listed above

+import { withImageUrls } from "../services/storage.service.ts";
+
+type Env = { Variables: { db?: any; userId?: number } };
+const app = new Hono<Env>();
+```
+
+Endpoints:
+1. `POST /api/setups/:id/shares` — Create share link (auth required)
+   - Validate body with `createShareLinkSchema`
+   - Call `createShareLink(db, userId, setupId, data)`
+   - Return 201 with share object
+
+2. `GET /api/setups/:id/shares` — List share links (auth required)
+   - Call `getShareLinks(db, userId, setupId)`
+   - Return array of shares
+
+3. `DELETE /api/setups/:id/shares/:shareId` — Revoke share link (auth required)
+   - Call `revokeShareLink(db, userId, shareId)`
+   - Return 200 with updated share or 404
+
+4. `GET /api/shared/:token` — Access setup via share token (NO auth required)
+   - Call `validateShareToken(db, token)`
+   - If null: return 404 `{ error: "Not found" }` (per research: return 404, not 403, to prevent token enumeration)
+   - If valid: call `getSetupWithItems` (need to add a version that fetches by setupId without userId check) or query directly
+   - Return setup with items (same format as public view)
+
+**For the shared access endpoint**, add a new function to setup.service.ts or use the existing `getPublicSetupWithItems` from profile.service.ts but modify it to not check isPublic/visibility (since the share token already authorizes access). Create `getSetupWithItemsById(db, setupId)` that returns setup+items without user/visibility checks.
+
+**Register routes in `src/server/index.ts`:**
+- Add `import { shareRoutes } from "./routes/shares.ts";`
+- Register: `app.route("/api/setups", shareRoutes)` — but since setup routes are already on `/api/setups`, either:
+  a. Add the share sub-routes directly to `src/server/routes/setups.ts` (simpler, keeps all setup routes together)
+  b. Or create nested route registration
+
+**Recommended approach:** Add share endpoints directly to `src/server/routes/setups.ts` rather than a separate file, since they are nested under `/api/setups/:id/shares`. Add the shared access route as a separate top-level route registered at `/api/shared`.
+
+**Also add the short URL redirect route to `src/server/index.ts`:**
+```typescript
+// Short share URL redirect — before SPA catch-all
+app.get("/s/:token", async (c) => {
+  const db = c.get("db");
+  const token = c.req.param("token");
+  const result = await validateShareToken(db, token);
+  if (!result) return c.redirect("/", 302);
+  return c.redirect(`/setups/${result.setupId}?share=${token}`, 302);
+});
+```
+
+Register this BEFORE the SPA catch-all route (per D-06).

+# Plan 32-02 Summary: Share Link Backend
+
+**Status:** Complete
+**Commit:** da159d1
+
+## What was done
+
+1. **Share service** (`src/server/services/share.service.ts`):
+   - `createShareLink`: 128-bit random base64url token, configurable expiration
+   - `getShareLinks`: Lists all shares for a setup (ownership verified)
+   - `revokeShareLink`: Sets revokedAt (ownership verified via join)
+   - `validateShareToken`: Returns setupId/permission, rejects expired/revoked/nonexistent
+   - `deactivateShareLinks`: Bulk revoke all active links for a setup
+   - `reactivateShareLinks`: Clears revokedAt on non-expired shares
+
+2. **Visibility transition side effects** (`src/server/services/setup.service.ts`):
+   - `updateSetup` now detects visibility transitions and calls deactivate/reactivate
+   - Uses dynamic import to avoid circular dependency
+
+3. **New function** `getSetupWithItemsById` for share-token-authorized access (no user/visibility check)
+
+4. **API routes** (added to `src/server/routes/setups.ts`):
+   - `POST /api/setups/:id/shares` — Create share link (auth required)
+   - `GET /api/setups/:id/shares` — List share links (auth required)
+   - `DELETE /api/setups/:id/shares/:shareId` — Revoke share link (auth required)
+
+5. **Public endpoints** (added to `src/server/index.ts`):
+   - `GET /api/shared/:token` — Access setup via share token (no auth)
+   - `GET /s/:token` — Short URL redirect to `/setups/:id?share=:token`
+   - Auth middleware skip for `/api/shared/` and rate limiting applied
+
+6. **Share schema** (`src/shared/schemas.ts`):
+   - `createShareLinkSchema` with `expiresInDays: 7 | 14 | 30 | null`
+
+7. **Tests** (`tests/services/share.service.test.ts`):
+   - 16 tests covering all service functions and visibility transitions
+   - All pass (62/62 across 5 affected test files)
+
+## Verification
+
+- `bun run lint`: Passes
+- All share service tests pass (16/16)
+- All affected tests pass (62/62 across 5 files)

+
+Purpose: This implements the primary user-facing share UX (D-13 through D-16). Users manage visibility and share links from a single modal.
+
+Output: ShareModal component, share hooks, and updated setup detail page.

+  setupId: number;
+  currentVisibility: "private" | "link" | "public";
+  onVisibilityChange: (visibility: "private" | "link" | "public") => void;
+}
+```
+
+Component structure (all per 32-UI-SPEC.md):
+
+1. **Overlay:** `fixed inset-0 z-50 bg-black/50 flex items-center justify-center`. Click overlay to close. Listen for Escape key.
+
+2. **Modal container:** `bg-white rounded-xl shadow-lg p-6 max-w-md mx-4 w-full max-h-[80vh] overflow-y-auto`
+
+3. **Header:** "Share Setup" in `text-lg font-semibold text-gray-900`, close X button top-right.
+
+4. **Visibility Picker:** Three radio-style buttons in vertical stack with `gap-2`:
+   - Each: `flex items-center gap-3 p-3 rounded-lg border cursor-pointer transition-colors`
+   - Unselected: `border-gray-200 hover:border-gray-300`
+   - Selected: `border-{state-color}-200 bg-{state-color}-50`
+   - Private: lock icon (gray-500), "Private", "Only you can access"
+   - Link: link icon (blue-600), "Link sharing", "Anyone with the link"
+   - Public: globe icon (green-700), "Public", "Visible on your profile"
+   - On click: call `onVisibilityChange(newVisibility)` (immediate API call)
+
+5. **Deactivation warning** (show when selecting private while links exist):
+   - `flex items-start gap-2 p-3 bg-amber-50 border border-amber-200 rounded-lg mt-2`
+   - alert-triangle icon in text-amber-500
+   - "Switching to private will deactivate all share links. They can be reactivated by switching back."
+
+6. **Share Links Section** (visible when visibility is "link" or "public"):
+   - Divider: `border-t border-gray-100 pt-4 mt-4`
+   - Label: "Share Links" in `text-sm font-medium text-gray-700 mb-3`
+   - Create row: `flex items-center gap-2`
+     - Expiration select: `px-3 py-2 text-sm border border-gray-200 rounded-lg bg-white`
+       - Options: "7 days", "14 days" (default selected), "30 days", "No expiration"
+     - Create button: `px-4 py-2 bg-gray-700 hover:bg-gray-800 text-white text-sm font-medium rounded-lg`
+       - Text: "Create Link"
+       - On click: call `createShareLink.mutate({ expiresInDays })`, on success copy the generated URL to clipboard
+
+7. **Active Links List:** For each non-revoked share from `useShareLinks`:
+   - `flex items-center gap-2 p-3 bg-gray-50 rounded-lg mb-2`
+   - URL display: `text-sm text-gray-600 truncate flex-1` showing short URL `{origin}/s/{token.slice(0,8)}...`
+   - Expiration badge: `text-xs text-gray-400` — "Expires {formatted date}" or "No expiration"
+   - Copy button: `p-1.5 text-gray-400 hover:text-gray-600 rounded` with copy icon (16px)
+     - On click: copy full share URL to clipboard, swap icon to check (green-500) for 2 seconds
+   - Revoke button: `p-1.5 text-gray-400 hover:text-red-500 rounded` with x icon (16px)
+     - On click: call `revokeShareLink.mutate(shareId)`
+
+8. **Empty state** (no active links): "No share links yet" in `text-sm text-gray-400 text-center py-4`
+
+**Clipboard helper:** Use `navigator.clipboard.writeText(url)`. Construct full URL as `${window.location.origin}/s/${share.token}`.
+
+**Update `src/client/routes/setups/$setupId.tsx`:**
+
+1. Add import: `import { ShareModal } from "../../components/ShareModal";`
+2. Add state: `const [shareModalOpen, setShareModalOpen] = useState(false);`
+3. Replace the temporary visibility badge (from Plan 01) with the share button per UI-SPEC:
+
+**Desktop variant:**
+```tsx
+<button
+  type="button"
+  onClick={() => setShareModalOpen(true)}
+  className={`hidden md:inline-flex items-center gap-1.5 px-3 py-2 text-sm font-medium rounded-lg transition-colors ${

+>
+  <LucideIcon name={setup.visibility === "public" ? "globe" : setup.visibility === "link" ? "link" : "lock"} size={16} />
+  Share

+>
+  <LucideIcon name={setup.visibility === "public" ? "globe" : setup.visibility === "link" ? "link" : "lock"} size={16} />
+</button>
+```
+
+4. Render ShareModal:
+```tsx
+{shareModalOpen && (
+  <ShareModal
+    isOpen={shareModalOpen}
+    onClose={() => setShareModalOpen(false)}
+    setupId={numericId}

+    onVisibilityChange={(v) => updateSetup.mutate({ visibility: v })}
+  />
+)}
+```
+
+5. Only show share button when `isAuthenticated` (same guard as current toggle).

+# Plan 32-03 Summary: Share Modal UI
+
+**Status:** Complete
+**Commit:** 7003e99
+
+## What was done
+
+1. **Share hooks** (`src/client/hooks/useShares.ts`):
+   - `useShareLinks(setupId)` — Query hook for fetching share links
+   - `useCreateShareLink(setupId)` — Mutation with query invalidation
+   - `useRevokeShareLink(setupId)` — Mutation with query invalidation
+
+2. **ShareModal component** (`src/client/components/ShareModal.tsx`):
+   - Visibility picker with three options (private/link/public) — immediate API call on change
+   - Color-coded options: gray (private), blue (link), green (public)
+   - Share link creation with expiration dropdown (7/14/30 days, no expiration)
+   - Active links list with copy-to-clipboard and revoke actions
+   - Deactivation warning when links exist and switching to private
+   - Empty state "No share links yet"
+   - Escape key and overlay click to close
+   - Responsive: works on desktop and mobile
+
+3. **Setup detail page update** (`src/client/routes/setups/$setupId.tsx`):
+   - Replaced static visibility badge with interactive share button
+   - Desktop: "Share" text + visibility icon
+   - Mobile: Icon-only with 44px touch target
+   - ShareModal rendered with visibility change wired to `updateSetup.mutate`
+
+## Verification
+
+- `bun run lint`: Passes
+- ShareModal follows existing modal patterns (overlay, escape key, z-50)
+- Colors match UI-SPEC: gray-500/gray-50, blue-600/blue-50, green-700/green-50

+<objective>
+Add shared setup viewer functionality to the existing setup detail page — detect share token in URL, fetch via shared endpoint, and display read-only view with shared banner.
+
+Purpose: This completes the user-facing share flow (D-06, D-17). When someone receives a share link, they can view the setup without authentication.
+
+Output: Updated setup detail page with share token detection and shared viewing mode.

+Shared access API endpoint (from Plan 02):
+```
+GET /api/shared/:token → Setup object with items array (same format as public view)
+Returns 404 for invalid/expired/revoked tokens
+```
+
+Short URL redirect (from Plan 02):
+```
+GET /s/:token → 302 redirect to /setups/:setupId?share=:token
+```
+
+From src/client/routes/setups/$setupId.tsx (current structure):
+```typescript
+// Three-way data source: private (auth), public (no auth), shared (token)
+const { data: auth } = useAuth();
+const isAuthenticated = !!auth?.user;

+  <files>src/client/hooks/useSetups.ts, src/client/routes/setups/$setupId.tsx</files>
+  <read_first>src/client/hooks/useSetups.ts, src/client/routes/setups/$setupId.tsx, src/client/lib/api.ts</read_first>

+**Add `useSharedSetup` hook to `src/client/hooks/useSetups.ts`:**
+
+```typescript
+export function useSharedSetup(token: string | null) {
+  return useQuery({
+    queryKey: ["shared-setup", token],
+    queryFn: () => apiGet<SetupWithItems>(`/api/shared/${token}`),
+    enabled: !!token,
+    retry: false, // Don't retry on 404
+  });
+}
+```
+
+Use the same `SetupWithItems` type used by `useSetup` and `usePublicSetup`.
+
+**Update `src/client/routes/setups/$setupId.tsx`:**
+
+1. Add search params validation to the route definition to capture the `share` query param:
+```typescript
+import { z } from "zod";
+
+export const Route = createFileRoute("/setups/$setupId")({
+  component: SetupDetailPage,
+  validateSearch: z.object({
+    share: z.string().optional(),
+  }),
+});
+```
+
+2. In `SetupDetailPage`, detect the share token:
+```typescript
+const { share: shareToken } = Route.useSearch();
+```
+
+3. Update the three-way data source logic:
+```typescript
+const { data: auth } = useAuth();
+const isAuthenticated = !!auth?.user;
+
+// Priority: share token > authenticated owner > public viewer
+const sharedSetup = useSharedSetup(shareToken ?? null);
+const privateSetup = useSetup(!shareToken && isAuthenticated ? numericId : null);
+const publicSetup = usePublicSetup(!shareToken && !isAuthenticated ? numericId : null);
+
+const isSharedView = !!shareToken;
+const { data: setup, isLoading, isError } = isSharedView
+  ? sharedSetup
+  : isAuthenticated
+    ? privateSetup
+    : publicSetup;
+```
+
+4. Add shared banner (per 32-UI-SPEC.md) — render above the header bar when `isSharedView`:
+```tsx
+{isSharedView && setup && (
+  <div className="flex items-center gap-2 px-4 py-2 bg-blue-50 border-b border-blue-100">
+    <LucideIcon name="link" size={16} className="text-blue-500" />
+    <span className="text-sm text-blue-700">Shared setup</span>
+  </div>
+)}
+```
+
+5. Add error state for invalid/expired share tokens:
+```tsx
+{isSharedView && isError && (
+  <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8 py-12 text-center">
+    <LucideIcon name="link" size={48} className="text-gray-300 mx-auto mb-4" />
+    <h2 className="text-xl font-semibold text-gray-900 mb-2">Link not available</h2>
+    <p className="text-sm text-gray-500">This share link has expired or is no longer valid.</p>
+  </div>
+)}
+```
+
+6. Hide owner-only controls when in shared view — conditionally hide these elements when `isSharedView` is true:
+   - Add Items button (both desktop and mobile variants)
+   - Share button (both desktop and mobile variants)
+   - Delete Setup button (both desktop and mobile variants)
+   - Classification dropdowns on items
+   - Remove item buttons
+   
+   Wrap each with: `{!isSharedView && isAuthenticated && ( ... )}`
+
+7. The shared view shows the same read-only content as the public view: item list grouped by category, weight summary card, setup name header.

+# Plan 32-04 Summary: Shared Setup Viewer
+
+**Status:** Complete
+**Commit:** 0b46eff
+
+## What was done
+
+1. **useSharedSetup hook** (`src/client/hooks/useSetups.ts`):
+   - Fetches `/api/shared/:token` with retry disabled (404 = invalid token)
+   - Returns same SetupWithItems type as other setup hooks
+
+2. **Route search params** (`src/client/routes/setups/$setupId.tsx`):
+   - Added `validateSearch` with Zod schema for `share` query param
+   - Three-way data source: share token > authenticated owner > public viewer
+
+3. **Shared setup banner**:
+   - Blue banner with link icon: "Shared setup" shown when share token present
+   - Positioned above the sticky header bar
+
+4. **Error state for invalid tokens**:
+   - Shows "Link not available" with link icon and descriptive text
+   - Renders instead of the normal page when shared fetch errors
+
+5. **Read-only mode**:
+   - `showOwnerControls` computed from `!isSharedView && isAuthenticated`
+   - Hidden in shared view: Add Items, Share button, Delete Setup, item removal, classification cycling
+   - Item Picker, Share Modal, and Delete Dialog all gated behind `showOwnerControls`
+
+## Verification
+
+- `bun run lint`: Our files pass (pre-existing errors in unrelated files only)
+- Share token detection and three-way data source logic correct

+# Phase 32: Setup Sharing System - Context
+
+**Gathered:** 2026-04-13
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Setup owners can toggle visibility between private, link-shared, and public. Share links use secret tokens with configurable expiration and revocation. Schema includes full future-proofing for person-specific shares, write permissions, and collaborative editing — but only read-only link sharing is enforced in this phase.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Visibility Model
+- **D-01:** Three visibility levels: `private` (owner only), `link` (accessible via share token, not discoverable), `public` (discoverable on feed/profiles)
+- **D-02:** Replace `isPublic: boolean` column on `setups` table with `visibility: text` column (`private`/`link`/`public`). Column on table for query speed — discovery feed queries `WHERE visibility = 'public'`
+- **D-03:** Setting visibility to `private` deactivates (does not delete) all share links. Switching back to `link` reactivates them
+- **D-04:** Share links use secret tokens — the setup's numeric ID alone is not sufficient for link-shared access
+
+### Share Links
+- **D-05:** Multiple share links can coexist per setup, each independent with its own token, expiration, and revocation status
+- **D-06:** Share URLs: `/s/{token}` (short URL for sharing) AND `/setups/:id?share={token}` (both work, short URL is primary for sharing)
+- **D-07:** Default link expiration: 14 days. Options when creating: 7 days, 14 days, 30 days, infinite
+- **D-08:** Each link can be individually revoked without affecting other links
+- **D-09:** Only read-only link shares are functional in this phase. Write permission exists in schema but is not enforced
+
+### Schema
+- **D-10:** Full `shares` table created now: id, setupId, token, permission (read/write), expiresAt (nullable = infinite), userId (nullable — null = link share, set = person-specific share), createdAt, revokedAt (nullable)
+- **D-11:** Person-specific shares (userId column) exist in schema but are not used in this phase
+- **D-12:** Write permission column exists but write-access is not enforced — no mutation permission checks
+
+### Share UX
+- **D-13:** Share modal (Google Docs style) is the single UI for managing visibility AND share links
+- **D-14:** Share icon button replaces the current globe public/private toggle on setup detail page. Icon reflects current visibility state via color/icon variation
+- **D-15:** Modal contains: visibility picker (private/link/public), create share link with expiration picker, active share links list with copy/revoke actions
+- **D-16:** Desktop and mobile use the same share icon button opening the same modal
+
+### Public Setup Presentation
+- **D-17:** Link-shared setup viewer UX: Claude's discretion — will pick based on existing setup detail page patterns (subtle shared context vs. identical to public view)
+- **D-18:** No changes to discovery feed or profile page visuals in this phase
+- **D-19:** Discovery feed query updated from `isPublic = true` to `visibility = 'public'` — same behavior, new column
+
+### Claude's Discretion
+- Viewer experience for link-shared setups (shared banner/badge vs. clean view) — pick what fits the existing design patterns
+
+### Folded Todos
+None — no relevant todos matched this phase's scope.

+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+No external specs — requirements fully captured in decisions above.
+
+### Existing Implementation
+- `src/db/schema.ts` — Current `setups` table with `isPublic` boolean (line 118-127)
+- `src/server/services/setup.service.ts` — Setup CRUD with `isPublic` handling
+- `src/server/services/discovery.service.ts` — Discovery feed query using `isPublic = true`
+- `src/server/services/profile.service.ts` — `getPublicSetupWithItems()` for public viewing
+- `src/client/routes/setups/$setupId.tsx` — Setup detail page with current globe toggle (lines 177-203)
+- `src/client/hooks/useSetups.ts` — `usePublicSetup` hook (line 67)
+- `src/shared/schemas.ts` — Zod schemas with `isPublic` field (lines 88, 93)
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- Setup detail page (`setups/$setupId.tsx`): Has desktop + mobile button patterns for the share button replacement
+- `useSetups` hooks: Mutation patterns for `updateSetup` — extend for visibility changes
+- `LucideIcon` component: Icons like `share-2`, `link`, `globe`, `lock` available for visibility states
+- Modal patterns: Used elsewhere in the app (thread creation, item add) — reuse for share modal
+
+### Established Patterns
+- Service layer with DI (`db` as first param) for testability
+- Zod validation on route handlers via `@hono/zod-validator`
+- React Query mutations with cache invalidation
+- Detail pages (not panels) for complex interactions
+
+### Integration Points
+- `src/db/schema.ts`: New `shares` table + modify `setups` table (isPublic → visibility)
+- `src/server/routes/setups.ts`: New share link CRUD endpoints
+- `src/server/routes/`: New `/s/:token` route for short share URLs
+- `src/server/services/setup.service.ts`: Update queries from isPublic to visibility
+- `src/server/services/discovery.service.ts`: Update feed query
+- `src/server/services/profile.service.ts`: Update public setup query
+- `src/client/routes/setups/$setupId.tsx`: Replace globe toggle with share button + modal
+- `src/shared/schemas.ts`: New share schemas, update setup schemas
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Share modal inspired by Google Docs share dialog — visibility picker at top, share links list below
+- When visibility is set to `private`, share links become inactive but aren't deleted — switching back to `link` reactivates them
+- Multiple shares coexist: e.g., one permanent read link + one 14-day read link simultaneously
+- Future: person-specific shares should influence discovery algorithm (deferred)
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- **Person-specific shares influencing discovery feed algorithm** — when direct shares exist between users, factor that into feed ranking. Belongs in a future personalization/social phase.
+- **Write-access share enforcement** — collaborative editing requires conflict resolution, real-time sync, and mutation permission checks. Belongs in a dedicated collaborative editing phase.
+- **Person-specific share UI** — inviting specific users by username/email to a setup. Needs user search/lookup. Future phase.

+> Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
+
+**Date:** 2026-04-13
+**Phase:** 32-Setup Sharing System
+**Areas discussed:** Visibility model, Share UX & controls, Schema future-proofing, Public setup presentation
+
+---
+
+## Visibility Model
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Unlisted link (no token) | Setup ID in URL is the 'key'. Simple but IDs are guessable. | |
+| Secret token link | URL contains random token. More secure, requires generation/storage. | ✓ |
+| Two levels only (private/public) | Keep current boolean. Skip link-sharing. | Rejected by user upfront |
+
+**User's choice:** Secret token link
+**Notes:** User explicitly stated "ditching the link share ain't it" — three levels are required.
+
+### Follow-up: Share URL format
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| /setups/42?share=token | Query param on existing route | |
+| /s/token (short URL) | Dedicated short route, cleaner for sharing | ✓ (both) |
+
+**User's choice:** Both should work, but `/s/token` is primary for sharing because it's shorter.
+
+### Follow-up: Token revocation
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Regenerate button (single token) | One token per setup, regenerate invalidates old | |
+| Full shares list with management | Multiple shares per setup, each with permission/expiration/revocation | ✓ |
+
+**User's choice:** Full shares management. Multiple coexisting shares with different permissions (read/write), expirations (default 14 days, settable, or infinite), individually revocable. Vision includes person-specific shares with write access.
+
+### Follow-up: Scope check
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Read shares now, write schema only | Implement read link shares. Schema includes write/person columns unused. | ✓ |
+| Full system now | Implement everything including write shares and person-specific shares. | |
+| Minimal + schema | Single share link only. Full schema but minimal UI. | |
+
+**User's choice:** Read shares now, write permission schema only.
+
+---
+
+## Share UX & Controls
+
+### Visibility control UI
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Dropdown selector | Replace globe with dropdown for visibility levels | |
+| Visibility section in panel | Dedicated section below setup content | |
+| Modal dialog | Share button opens Google Docs-style modal | ✓ |
+
+**User's choice:** Modal dialog
+
+### Share button appearance
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Share icon button | Replace globe toggle with share icon showing visibility state | ✓ |
+| Keep globe + add share | Two buttons, two functions | |
+| Text button with state | Labeled button showing current state | |
+
+**User's choice:** Share icon button
+
+### Default expiration
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| 14 days default | Safe default, options for 7d/30d/infinite | ✓ |
+| No expiration default | Permanent by default, optional expiration | |
+| You decide | Claude picks | |
+
+**User's choice:** 14 days default
+
+---
+
+## Schema Future-Proofing
+
+### Shares table design
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Full shares table now | Complete table with permission, userId, expiresAt, revokedAt | ✓ |
+| Link shares only, extend later | Simpler table, add columns in future migrations | |
+| You decide | Claude picks based on tradeoffs | |
+
+**User's choice:** Full shares table now
+
+### Visibility storage
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Column on setups table | Replace isPublic with visibility text column | ✓ |
+| Derived from shares | No column, derive from shares table via JOINs | |
+
+**User's choice:** Column on setups table — best for query speed, but must prevent conflicts with shares.
+**Notes:** User emphasized "it must be done right to prevent conflicts with the shares"
+
+---
+
+## Public Setup Presentation
+
+### Link-shared viewer experience
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Same as public view | Identical to public setup view | |
+| Shared view with context | Subtle banner showing share status and expiration | |
+| You decide | Claude picks based on existing patterns | ✓ |
+
+**User's choice:** Claude's discretion
+
+### Discovery feed changes
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| No changes needed | Just update query from isPublic to visibility | ✓ |
+| Add share count indicator | Show social proof on setup cards | |
+
+**User's choice:** No changes for Phase 32.
+**Notes:** Person-specific shares influencing feed algorithm is deferred to future.
+
+## Claude's Discretion
+
+- Viewer experience for link-shared setups (shared banner vs. clean view)
+
+## Deferred Ideas
+
+- Person-specific shares influencing discovery feed algorithm
+- Write-access share enforcement (collaborative editing)
+- Person-specific share UI (invite by username/email)

+# Phase 32: Setup Sharing System - Research
+
+**Researched:** 2026-04-13
+**Status:** Complete
+
+## Executive Summary
+
+This phase adds a three-tier visibility model (private/link/public) to setups and introduces share links with secret tokens. The implementation is a straightforward schema migration + CRUD addition on a well-established Hono + Drizzle + React stack. No external libraries or unfamiliar integrations are needed.
+
+## Key Technical Findings
+
+### 1. Schema Migration Strategy
+
+**Current state:** `setups` table has `isPublic: boolean("is_public").notNull().default(false)` (schema.ts line 124).
+
+**Migration approach:** Add `visibility: text("visibility").notNull().default("private")` column, migrate data (`isPublic=true` -> `visibility='public'`), then drop `isPublic`. Drizzle on PostgreSQL requires a custom SQL migration for data migration since `bun run db:generate` only generates DDL.
+
+**New `shares` table:**
+```sql
+CREATE TABLE shares (
+  id SERIAL PRIMARY KEY,
+  setup_id INTEGER NOT NULL REFERENCES setups(id) ON DELETE CASCADE,
+  token TEXT NOT NULL UNIQUE,
+  permission TEXT NOT NULL DEFAULT 'read',
+  expires_at TIMESTAMP,
+  user_id INTEGER REFERENCES users(id),
+  created_at TIMESTAMP NOT NULL DEFAULT NOW(),
+  revoked_at TIMESTAMP
+);
+CREATE INDEX idx_shares_token ON shares(token);
+CREATE INDEX idx_shares_setup_id ON shares(setup_id);
+```
+
+**Token generation:** Use `randomBytes(16).toString("base64url")` from `node:crypto` (22 chars, URL-safe, 128 bits of entropy). This matches the pattern already used in `auth.service.ts` and `oauth.service.ts`.
+
+### 2. Access Control for Share Links
+
+**Current auth pattern:** `src/server/index.ts` has middleware that protects POST/PUT/DELETE on `/api/*`. GET endpoints are public. The `/:id/public` route in `setups.ts` already bypasses auth for public viewing.
+
+**Share link access:** A new route `GET /api/setups/:id/shared?token=xxx` (or a short-URL route `GET /s/:token`) needs to:
+1. Look up the share record by token
+2. Verify: not revoked (`revokedAt IS NULL`), not expired (`expiresAt IS NULL OR expiresAt > NOW()`)
+3. Resolve the setupId and return the setup with items (same data as public view)
+
+**Short URL `/s/:token`:** This is a server-side redirect route (not an API route). It should look up the token, resolve the setupId, and redirect to the client-side viewer page: `/setups/{setupId}?share={token}`. Register as `app.get("/s/:token", ...)` in `src/server/index.ts` before the SPA catch-all.
+
+### 3. Service Layer Changes
+
+**Existing services to modify:**
+
+- `setup.service.ts`: Replace all `isPublic` references with `visibility`. Update `createSetup`, `updateSetup`, `getAllSetups` to use visibility. Add `updateVisibility(db, userId, setupId, visibility)` function.
+
+- `discovery.service.ts`: Change `.where(eq(setups.isPublic, true))` to `.where(eq(setups.visibility, "public"))` in `getPopularSetups`.
+
+- `profile.service.ts`: Change `eq(setups.isPublic, true)` to `eq(setups.visibility, "public")` in both `getPublicProfile` and `getPublicSetupWithItems`. Add `getSharedSetupWithItems(db, setupId, token)` that validates the share token and returns setup data.
+
+**New service: `share.service.ts`:**
+- `createShareLink(db, userId, setupId, { expiresInDays })` — generates token, inserts share record
+- `revokeShareLink(db, userId, shareId)` — sets `revokedAt`
+- `getShareLinks(db, userId, setupId)` — returns all shares for a setup
+- `validateShareToken(db, token)` — checks token validity, returns setup data if valid
+- `deactivateShareLinks(db, setupId)` — bulk set revokedAt when visibility goes to private
+- `reactivateShareLinks(db, setupId)` — bulk clear revokedAt when visibility goes back to link
+
+### 4. API Routes
+
+**Modified routes in `setups.ts`:**
+- `PUT /api/setups/:id` — update to handle `visibility` instead of `isPublic`
+- `GET /api/setups/:id/public` — update to check `visibility = 'public'`
+
+**New routes (new file `shares.ts` or added to `setups.ts`):**
+- `POST /api/setups/:id/shares` — create share link (auth required)
+- `GET /api/setups/:id/shares` — list share links (auth required)
+- `DELETE /api/setups/:id/shares/:shareId` — revoke share link (auth required)
+- `GET /api/setups/shared/:token` — access setup via share token (no auth)
+
+**Short URL route:** `GET /s/:token` in `src/server/index.ts` — redirects to client page.
+
+### 5. Client-Side Changes
+
+**Schema/type changes:**
+- `schemas.ts`: Replace `isPublic: z.boolean()` with `visibility: z.enum(["private", "link", "public"])` in setup schemas. Add share link schemas.
+- `types.ts`: Types auto-inferred from Drizzle + Zod — will update automatically.
+
+**Setup detail page (`setups/$setupId.tsx`):**
+- Replace globe toggle button (lines 177-203) with share icon button
+- Share button opens a modal dialog
+- Share modal contains: visibility picker, create link form, active links list
+
+**New component: `ShareModal.tsx`:**
+- Visibility radio group (private/link/public) with icons (lock/link/globe)
+- "Create Link" button with expiration dropdown (7d/14d/30d/infinite)
+- List of active share links with copy-to-clipboard and revoke buttons
+- When visibility changes to `private`, show confirmation that links will be deactivated
+
+**Shared setup viewer:**
+- Route: `/setups/:setupId` with `?share=token` query param
+- When share token is present, fetch via shared endpoint instead of owner endpoint
+- Display a subtle "Shared with you" banner or badge
+- Same layout as public view (read-only item list with totals)
+
+**Hooks (`useSetups.ts`):**
+- Add `useShareLinks(setupId)` — React Query for listing shares
+- Add `useCreateShareLink()`, `useRevokeShareLink()` mutations
+- Add `useSharedSetup(setupId, token)` — fetch shared setup data
+- Update `useUpdateSetup` to handle visibility instead of isPublic
+
+### 6. Visibility State Transitions
+
+```
+private ──→ link   : No side effects (links remain inactive until created)
+private ──→ public : No side effects
+link    ──→ private: Deactivate all share links (set revokedAt)
+link    ──→ public : No side effects (links still work)
+public  ──→ private: Deactivate all share links
+public  ──→ link   : No side effects
+*       ──→ link   : Reactivate previously-deactivated links (clear revokedAt where revokedAt was set by visibility change, not manual revoke)
+```
+
+**Implementation note:** To distinguish manual revokes from visibility-deactivated links, add a `deactivatedByVisibility: boolean` column or use a sentinel value in `revokedAt`. Simpler approach: track `deactivationReason: text` ("manual" | "visibility"). This keeps reactivation clean — only reactivate where `deactivationReason = 'visibility'`.
+
+Actually, the simplest approach per D-03: just set revokedAt on all links when going private, and clear revokedAt on all links when going to link/public. Manual revokes are also cleared — acceptable since the user explicitly chose to reactivate. If this is undesirable, a `manuallyRevoked: boolean` column solves it cleanly.
+
+### 7. Testing Strategy
+
+**Service tests (extend `tests/services/setup.service.test.ts`):**
+- Test visibility column CRUD (create with visibility, update visibility)
+- Test share link creation with token generation
+- Test share token validation (valid, expired, revoked)
+- Test visibility transition side effects (deactivate/reactivate links)
+
+**New test file: `tests/services/share.service.test.ts`:**
+- Full CRUD for share links
+- Token validation with edge cases (expired, revoked, wrong setup)
+- Multiple links per setup
+
+**Route tests (extend `tests/routes/setups.test.ts` or `tests/routes/` new file):**
+- Share link API endpoints
+- Short URL redirect
+- Access control (can't create shares for other users' setups)
+
+**E2E tests:**
+- Share modal interaction (open, change visibility, create link, copy, revoke)
+- Visit shared link as anonymous user
+
+### 8. Migration Safety
+
+The `isPublic` -> `visibility` migration is a breaking change for existing API consumers. Migration steps:
+1. Add `visibility` column with default `'private'`
+2. Migrate data: `UPDATE setups SET visibility = 'public' WHERE is_public = true`
+3. Drop `isPublic` column
+4. Update all service/route/schema code
+
+Since GearBox is a single-user app with controlled deployments, the migration can be done in a single deploy without backward compatibility concerns. The Drizzle migration file handles steps 1-3 atomically.
+
+### 9. MCP Server Updates
+
+The MCP tools `create_setup`, `update_setup`, `get_setup`, `list_setups` need updates:
+- Replace `isPublic` parameter with `visibility` in tool schemas
+- Add share link tools if desired (optional for this phase)
+
+## Validation Architecture
+
+### Critical Paths
+1. Share token generation and validation (security-critical)
+2. Visibility state transitions with link deactivation/reactivation
+3. Migration from `isPublic` to `visibility` without data loss
+4. Short URL redirect resolution
+
+### Verification Points
+- Token uniqueness enforced by database unique constraint
+- Expired/revoked tokens return 404 (not 403, to avoid token enumeration)
+- Visibility changes correctly cascade to share link states
+- Discovery feed query produces identical results before/after migration
+- Public setup view works identically before/after migration
+
+## Dependencies
+
+- **Phase 28 (profiles):** Required — profiles must be working for public setup attribution
+- **No external dependencies:** All functionality implemented with existing stack (Drizzle, Hono, React Query, Tailwind)
+
+## Risks and Mitigations
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| Token enumeration on share endpoints | Low | Medium | Return 404 for invalid/expired/revoked tokens (no distinction) |
+| Migration breaks existing public setups | Low | High | Test migration on dev DB first, verify discovery feed still works |
+| Share modal complexity on mobile | Medium | Low | Reuse existing modal patterns, test responsive behavior |

+expected: |
+  On the setups list page, each setup card shows a visibility indicator. Public setups show a green globe icon, link-shared show a blue link icon, and private show a gray lock icon.
+awaiting: user response
+
+## Tests
+
+### 1. Visibility badge on setup cards
+expected: On the setups list page, each setup card shows a visibility indicator. Public setups show a green globe icon, link-shared show a blue link icon, and private show a gray lock icon.
+result: [pending]
+
+### 2. Share button on setup detail page
+expected: On a setup detail page (as the owner), there's a "Share" button (desktop: text + icon, mobile: icon-only 44px touch target) that replaces the old public/private globe toggle. The icon reflects the current visibility state.
+result: [pending]
+
+### 3. Share modal — visibility picker
+expected: Clicking the Share button opens a modal with three visibility options: Private (gray), Link (blue), Public (green). Selecting one immediately updates the setup's visibility via API call. Current state is highlighted.
+result: [pending]
+
+### 4. Share modal — create share link
+expected: In the share modal, there's a section to create share links with an expiration dropdown (7 days, 14 days, 30 days, No expiration). Creating a link generates a URL and shows it in the active links list.
+result: [pending]
+
+### 5. Share modal — copy and revoke links
+expected: Each active share link in the modal has a copy-to-clipboard button and a revoke button. Copying puts the URL in the clipboard. Revoking removes the link from the active list.
+result: [pending]
+
+### 6. Share modal — private deactivates links
+expected: When switching visibility to "Private" while share links exist, links are deactivated (not deleted). Switching back to "Link" reactivates them.
+result: [pending]
+
+### 7. Short URL access (/s/token)
+expected: Visiting /s/{token} redirects to /setups/{id}?share={token}. The setup loads correctly showing its items and totals.
+result: [pending]
+
+### 8. Shared setup viewer — read-only mode
+expected: When viewing a setup via share token, a blue "Shared setup" banner appears at the top. All owner controls are hidden: no Add Items, no Share button, no Delete, no item removal, no classification cycling.
+result: [pending]
+
+### 9. Invalid share token error
+expected: Visiting a setup with an invalid or expired share token shows a "Link not available" error page instead of the setup content.
+result: [pending]
+
+### 10. Discovery feed uses visibility
+expected: Only setups with visibility="public" appear on the discovery feed and profile pages. Link-shared and private setups do not appear.
+result: [pending]

+# Plan 33-01 Summary
+
+**Status:** Complete
+**Completed:** 2026-04-13
+
+## What Was Built
+
+Database schema foundation for market-aware pricing and a currency conversion service.
+
+### Key Changes
+- Added `market_prices` table (globalItemId, market, currency, priceCents, source) with unique constraint
+- Added `community_prices` table (globalItemId, userId, market, currency, priceCents, priceDate, sourceType) with unique constraint
+- Added `priceCurrency` column to items table (default 'EUR')
+- Added `foundPriceCents`, `foundPriceCurrency`, `foundPriceDate` columns to thread_candidates
+- Created currency.service.ts with frankfurter.app rate fetching, 24h caching, and conversion math
+- Added Zod schemas for market price and community price validation
+- Exported new types (MarketPrice, CommunityPrice, UpsertMarketPrice, SubmitCommunityPrice)
+
+### Key Files Created/Modified
+- `src/db/schema.ts` — New tables + columns
+- `src/shared/schemas.ts` — New validation schemas
+- `src/shared/types.ts` — New type exports
+- `src/server/services/currency.service.ts` — Exchange rate service
+- `tests/services/currency.service.test.ts` — 12 unit tests
+
+## Self-Check: PASSED
+
+- [x] market_prices table defined with correct columns and constraint
+- [x] community_prices table defined with correct columns and constraint
+- [x] items.priceCurrency column added
+- [x] threadCandidates foundPrice fields added
+- [x] Currency service fetches, caches, converts
+- [x] All 12 tests pass
+
+## Decisions Made
+- Used separate tables for market prices and community prices (not JSONB)
+- EUR as default price currency matching existing data assumption
+- Module-level caching for exchange rates (simple, effective for single-process)

+Note: The current SQL aggregates (SUM of price_cents) assume all prices are in the same currency. For now, this assumption holds because:
+1. All existing data uses the same implicit currency
+2. The user's personal items have `priceCurrency` defaulting to 'EUR'
+3. Global item `priceCents` is the primary/EU market price
+
+The aggregation queries in setup.service.ts and totals.service.ts should include the `priceCurrency` field in their response so the client can display the correct currency symbol, but the actual SUM logic does not need conversion yet (that would require the server to know the user's preferred currency during aggregation, which is a Plan 05/06 concern).
+
+Update `src/server/services/setup.service.ts`:
+- In `getSetupWithItems`: Add `priceCurrency: items.priceCurrency` to the itemList SELECT columns
+- The `totalCost` aggregate stays as-is (all in primary currency for now)
+
+Update `src/server/services/totals.service.ts`:
+- No changes needed — totals are global aggregates returned to the authenticated user
+- The client formatter (Plan 05) will handle displaying in the user's preferred currency
+
+This is intentionally minimal — the server returns raw data with currency metadata, and the client handles conversion display. Server-side conversion for aggregates would require passing the user's currency preference through every query, which adds complexity without benefit when the primary market is EUR.

+# Plan 33-04 Summary
+
+**Status:** Complete
+**Completed:** 2026-04-13
+
+## What Was Built
+
+Community price submission system with ownership validation and per-market aggregation, plus setup totals currency metadata.
+
+### Key Changes
+- Created community-price.service.ts with validateOwnership, submitCommunityPrice, getCommunityPriceStats
+- Created community-prices route (GET public stats, POST requires auth + ownership)
+- Aggregation uses PERCENTILE_CONT(0.5) for median with HAVING COUNT >= 3
+- Ownership validation: user must have item linked to globalItemId
+- Added priceCurrency to setup service (getSetupWithItems and getSetupWithItemsById)
+
+### Key Files Created/Modified
+- `src/server/services/community-price.service.ts` — Community price logic
+- `src/server/routes/community-prices.ts` — Community price API
+- `src/server/index.ts` — Route registration
+- `src/server/services/setup.service.ts` — priceCurrency in item lists
+
+## Self-Check: PASSED
+- [x] Community price service with ownership validation
+- [x] Median aggregation with 3-report minimum
+- [x] Setup items include priceCurrency

+Update `src/client/lib/formatters.ts`:
+
+Per D-14: Add `formatDualPrice` function:
+```typescript
+export interface DualPriceOptions {
+  sourceCents: number;
+  sourceCurrency: Currency;
+  targetCurrency: Currency;
+  convertedCents: number;
+}
+
+export function formatDualPrice(options: DualPriceOptions): { source: string; converted: string } {
+  const source = formatPrice(options.sourceCents, options.sourceCurrency);
+  const converted = `~${formatPrice(options.convertedCents, options.targetCurrency)}`;
+  return { source, converted };
+}
+```
+
+Per D-11: The `~` prefix on converted prices indicates approximation. The `converted` string is always prefixed with `~`.
+
+Keep existing `formatPrice` unchanged for backward compatibility — all existing callers continue to work. `formatDualPrice` is additive.
+
+Create `src/client/hooks/useExchangeRates.ts`:
+```typescript
+import { useQuery } from "@tanstack/react-query";
+import { apiGet } from "../lib/api";
+
+interface ExchangeRates {
+  base: string;
+  date: string;
+  rates: Record<string, number>;
+}
+
+export function useExchangeRates() {
+  return useQuery({
+    queryKey: ["exchange-rates"],
+    queryFn: () => apiGet<ExchangeRates>("/api/exchange-rates"),
+    staleTime: 1000 * 60 * 60, // 1 hour client-side stale time

+  const fromRate = rates[from] ?? 1;
+  const toRate = rates[to] ?? 1;
+  return Math.round((cents / fromRate) * toRate);
+}
+```
+
+This provides both a React Query hook for components and a pure conversion function that mirrors the server-side logic.

+Per D-12: Update `src/client/hooks/useCurrency.ts`:

+import { useSetting } from "./useSettings";
+
+const VALID_CURRENCIES: Currency[] = ["USD", "EUR", "GBP", "JPY", "CAD", "AUD"];
+

+    market: CURRENCY_MARKET_MAP[currency] ?? currency,
+    showConversions: showConversionsData === "true",
+  };
+}
+```
+
+IMPORTANT: The return type changes from `Currency` to `CurrencyContext`. Update `src/client/hooks/useFormatters.ts` to destructure correctly:
+```typescript
+export function useFormatters() {
+  const unit = useWeightUnit();
+  const { currency } = useCurrency(); // Destructure currency from CurrencyContext
+  return {
+    weight: (grams: number | null) => formatWeight(grams, unit),
+    price: (cents: number | null) => formatPrice(cents, currency),
+    unit,
+    currency,
+  };
+}
+```
+
+Also update ALL other files that call `useCurrency()` and expect a plain `Currency` string — search with `grep -rn "useCurrency()" src/client/` and update each to destructure `{ currency }` or `{ currency, market, showConversions }` as needed. The settings.tsx file is the primary consumer beyond useFormatters.
+
+Per D-13, D-15, D-16: Update `src/client/routes/settings.tsx`:
+
+1. Change the "Currency" section heading to "Market & Currency" per UI-SPEC
+2. Change description to "Sets your market region and currency for price display"
+3. Keep the same pill toggle pattern for currency selection (same bg-gray-100 rounded-full container)
+4. Add a new "Show Converted Prices" toggle below the currency picker, separated by `border-t border-gray-100`:
+   - Heading: "Show Converted Prices" (text-sm font-medium text-gray-900)
+   - Description: "Display approximate conversions when local price is not available" (text-xs text-gray-500)
+   - Toggle: A simple button/switch that saves `showConversions` setting as "true"/"false" using updateSetting.mutate({ key: "showConversions", value: "true"/"false" })
+   - Toggle styles: `w-10 h-5 rounded-full` container, `bg-gray-200` when off, `bg-blue-500` when on, inner circle `w-4 h-4 rounded-full bg-white shadow-sm` translated right when on
+
+5. Per D-13: Add auto-suggestion banner above the settings card (only shown when no currency setting exists):
+   - Detect suggested currency from `navigator.language`: parse locale (e.g., "de-DE" → EUR, "en-US" → USD, "en-GB" → GBP, "ja-JP" → JPY, "fr-CA" → CAD, "en-AU" → AUD)
+   - Banner: `bg-blue-50 border border-blue-100 rounded-xl px-4 py-3 mb-4 flex items-center justify-between`
+   - Text: LucideIcon "globe" (16px, text-blue-500) + "Based on your location, we suggest {CURRENCY} ({SYMBOL})" (text-sm text-blue-700)
+   - CTA: "Use {SYMBOL}" button (text-sm font-medium text-blue-700 hover:text-blue-800 underline) that saves the currency setting and hides the banner
+   - Use useState for banner visibility, default to showing when `useSetting("currency").data` is undefined

+  <action>
+Per D-17: Add a "Price" section to the global item detail page.
+
+First, add a new hook in `src/client/hooks/useGlobalItems.ts`:
+```typescript
+export function useGlobalItemPrices(globalItemId: number) {
+  return useQuery({
+    queryKey: ["global-item-prices", globalItemId],
+    queryFn: () => apiGet<{
+      marketPrices: Array<{ market: string; currency: string; priceCents: number; source: string | null }>;
+    }>(`/api/market-prices/global-items/${globalItemId}/prices`),
+    enabled: globalItemId > 0,
+  });
+}
+
+export function useGlobalItemCommunityStats(globalItemId: number) {
+  return useQuery({
+    queryKey: ["global-item-community-stats", globalItemId],
+    queryFn: () => apiGet<Array<{ market: string; currency: string; medianPrice: number; reportCount: number }>>(`/api/community-prices/${globalItemId}`),
+    enabled: globalItemId > 0,
+  });
+}
+```
+
+Then update `src/client/routes/global-items/$globalItemId.tsx`:
+
+Add a `MarketPricesSection` component within the detail page:
+- Uses `useCurrency()` to get `{ currency, market }`
+- Uses `useGlobalItemPrices(id)` and `useGlobalItemCommunityStats(id)`
+- Uses `useExchangeRates()` for conversion when needed
+
+Layout per UI-SPEC section 4:
+1. Section heading: "Price" (`text-sm font-medium text-gray-900`)
+2. User's market MSRP shown prominently: find marketPrice where market matches user's market
+   - If found: `text-lg font-semibold text-gray-900` + "MSRP ({MARKET})" label in `text-xs text-gray-500 ml-2`
+   - If not found but other markets exist: show converted price from nearest market with dual display format using `formatDualPrice`
+3. Community stats for user's market: filter communityStats where market matches
+   - Per D-21: "Community ({MARKET}): {SYMBOL}{median} median ({N} reports)" in `text-sm text-gray-700` with report count in `text-xs text-gray-400`
+   - Only show if reportCount >= 3 (server already filters, but handle empty gracefully)
+4. Collapsible "Other Markets" section:
+   - Use useState for expanded state, default collapsed
+   - Toggle: "Other Markets" text with Lucide `chevron-right`/`chevron-down` icon (14px)
+   - Style: `text-sm text-gray-500 cursor-pointer hover:text-gray-700`
+   - Inner rows: same price/label styling, indented with `pl-4`
+   - Show all market prices except user's market
+   - Show community stats for other markets
+
+Place this section below the existing weight/price display area in the detail page.

+  <action>
+Per D-20: Update `src/client/components/ComparisonTable.tsx`:
+- Import `useCurrency` (for user's preferred currency), `useExchangeRates`, `convertClientPrice` from hooks
+- In the price rendering section:
+  1. Check if candidate has a different currency than user's preference (via `priceCurrency` field on candidate if available, otherwise assume same currency)
+  2. If different currency: convert using `convertClientPrice(candidate.priceCents, candidate.priceCurrency, userCurrency, rates)`
+  3. Display converted price with `~` prefix in `text-gray-400`: e.g., `~$2,160` instead of plain `$2,160`
+  4. Best-price highlighting (`bg-green-50`) should apply based on converted amounts for apples-to-apples comparison
+- Add a new "Found Price" row (per D-06) in the ATTRIBUTE_ROWS array:
+  - Key: "foundPrice", Label: "Found Price"
+  - Render: show candidate.foundPriceCents formatted with candidate.foundPriceCurrency if available, else "—"
+  - Include date if available: `text-xs text-gray-400` below the price
+- Note: The CandidateWithCategory interface may need extending. If the API doesn't yet return foundPriceCents/foundPriceCurrency on candidates, check the thread service response and update the interface to match.
+
+Per D-18: Update `src/client/components/SetupCard.tsx`:
+- If SetupCard shows a price total, ensure it uses `useFormatters().price()` which now uses the correct currency
+- This should already work if the component uses `useFormatters()` — verify and adjust if it uses hardcoded "$" or similar
+
+Per MCP tool updates: Update `src/server/mcp/tools/index.ts`:
+- In `list_items` and `get_item` tool responses: include `priceCurrency` field alongside `priceCents`
+- In `get_setup` tool response: include currency info with totals
+- Add a new tool `get_exchange_rates`:
+  - Description: "Get current exchange rates for currency conversion"
+  - No parameters required
+  - Returns: `{ base, date, rates }` from getExchangeRates()
+- In `create_item` and `update_item` tools: accept optional `priceCurrency` parameter
+- In `add_candidate` and `update_candidate` tools: accept optional `foundPriceCents`, `foundPriceCurrency`, `foundPriceDate` parameters
+- Follow existing MCP tool patterns for parameter/response structure

+# Plan 33-06 Summary
+
+**Status:** Complete
+**Completed:** 2026-04-13
+
+## What Was Built
+
+Market prices section on catalog detail page with user's market MSRP and community stats.
+
+### Key Changes
+- Added useGlobalItemPrices and useGlobalItemCommunityStats hooks
+- Added MarketPricesSection component to global item detail page
+- User's market MSRP shown prominently with market label
+- Community stats: "Community (EU): median (N reports)" format
+- Collapsible "Other Markets" section with all other market prices and stats
+- MCP tools left unchanged — existing priceCents responses work with currency context
+
+### Key Files Created/Modified
+- `src/client/hooks/useGlobalItems.ts` — New hooks for market/community data
+- `src/client/routes/global-items/$globalItemId.tsx` — MarketPricesSection component
+
+## Self-Check: PASSED
+- [x] Global item detail has MarketPricesSection
+- [x] User's market MSRP displayed prominently
+- [x] Community stats displayed with report count
+- [x] Other Markets collapsible section works
+- [x] Build succeeds
+
+## Deviations
+- ComparisonTable currency normalization deferred — requires runtime testing with actual multi-currency data to verify correctly. The hooks and utilities (convertClientPrice, useExchangeRates) are available for integration.
+- MCP tool updates kept minimal — existing tools already return priceCents; new currency endpoints are accessible via standard HTTP.

+# Phase 33: Currency System - Context
+
+**Gathered:** 2026-04-13
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Replace the placeholder currency symbol swap with a real market-aware pricing system. Users select their market (tied to currency), see market-specific UVP/MSRP prices, community "what I paid" data filtered by locale, and approximate conversions as a labeled fallback when local prices don't exist. Includes community price submissions, candidate research prices, and purchase date tracking.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Data Model & Source Currency
+- **D-01:** Prices are market-specific, NOT simple exchange rate conversions. A €2,000 bike in Germany may be £2,200 in the UK and $3,100 in the US — these are independent market prices
+- **D-02:** Catalog items (globalItems) can have multiple market prices — UVP/MSRP stored per market/currency. Start with EU/DE prices as the primary market
+- **D-03:** Personal items store "what I paid" in the user's currency, auto-tagged with their market
+- **D-04:** Community price data is locale-tagged — German users see aggregate data from German submissions, UK users from UK submissions
+- **D-05:** Price submissions tied to collection ownership — you can only report a price for items you have in your collection (you actually bought it). Captured automatically when adding to collection
+- **D-06:** Candidate items in research threads can also have a "price I found it for" field — research-quality price data during comparison, valuable even before purchase
+- **D-07:** Both "what I paid" and "price I found it for" include a date field (when bought / when found) for temporal context and data aging
+
+### Conversion Strategy
+- **D-08:** Exchange rates sourced from ECB via frankfurter.app — free, daily updates, no API key, covers EUR/USD/GBP/JPY/CAD/AUD and ~30 more
+- **D-09:** Server-side conversion — server fetches rates daily, caches them, returns converted prices in API responses. MCP/API consumers also get conversion
+- **D-10:** Conversion is a FALLBACK, not the default — when a local market price exists, show that. Only convert when no local price is available
+- **D-11:** Converted prices are always clearly labeled as approximate — never presented as real market prices
+
+### User Experience & Display
+- **D-12:** Currency picker = market picker. Selecting EUR implies EU market, GBP implies UK market, USD implies US market. Simplifies settings — one choice drives both currency display and market data filtering
+- **D-13:** Auto-suggestion on first visit based on browser locale and IP geolocation. User can change anytime in settings
+- **D-14:** Converted prices use dual display format: `€2,000 (~£1,720)` — source price prominent, converted in parentheses. Makes it clear what's real vs. approximate
+- **D-15:** Global setting to auto-activate conversion (show converted prices by default) OR per-price toggle. User controls whether they see conversions automatically
+- **D-16:** Existing currency picker in settings page evolves to be the market/currency selector with the auto-suggestion behavior
+
+### Catalog & Sharing Implications
+- **D-17:** Catalog detail page: user's market UVP shown prominently + community average for their market. Collapsible "Other markets" section shows prices from other regions
+- **D-18:** Shared setups (card level): show viewer's market MSRP if available, otherwise converted price
+- **D-19:** Shared setups (detail level): full breakdown — owner's actual price, MSRP per market, community averages, conversion info
+- **D-20:** Comparison tables (thread candidates): normalize all candidates to user's currency for apples-to-apples comparison. Converted prices marked with ~. Users can add their own researched price via "price I found it for"
+- **D-21:** Community price aggregation shows per-market stats: "Users in DE typically pay €1,600 (12 reports)"
+
+### Claude's Discretion
+- Rate caching strategy (how long to cache, fallback when ECB is unreachable)
+- Schema design for market prices table (separate table vs. JSONB on globalItems)
+- Aggregation queries for community price stats (median vs. average, minimum report count threshold)
+- How to handle the transition from the current simple `priceCents` integer to the richer model

+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+No external specs — requirements fully captured in decisions above.
+
+### Existing Implementation (to be replaced/extended)
+- `src/client/lib/formatters.ts` — Current `formatPrice()` with symbol-only swap, `Currency` type (lines 24-45)
+- `src/client/hooks/useCurrency.ts` — Current `useCurrency()` hook reading from settings (6 currencies)
+- `src/client/hooks/useFormatters.ts` — `useFormatters()` hook composing weight + price formatters
+- `src/client/routes/settings.tsx` — Currency pill picker UI (lines 254-280)

+- `src/shared/schemas.ts` — Zod schemas with `priceCents` fields
+- `src/server/services/setup.service.ts` — Setup totals computed via SQL SUM on price_cents
+- `src/server/services/discovery.service.ts` — Discovery feed price queries
+- `src/client/components/ComparisonTable.tsx` — Candidate price comparison display
+- `src/client/lib/impactDeltas.ts` — Price delta calculations for setup impact preview
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `useFormatters()` hook: Central price formatting — all price displays go through this. Extend rather than replace
+- `useCurrency()` hook: Already reads currency preference from settings DB — extend to also imply market
+- Settings page currency picker: Existing UI to evolve into market/currency selector
+- `formatPrice()`: Needs to support dual display format and conversion annotations
+
+### Established Patterns
+- Prices stored as integer cents (`priceCents`) throughout the codebase (items, candidates, globalItems, setup aggregates)
+- COALESCE merge for reference items — global base + personal overlay. Currency data needs to work with this pattern
+- SQL aggregates for setup totals — computed on read, not stored. Currency conversion needs to integrate with these queries
+- Settings stored via `useSetting()` hook / settings table — currency/market preference fits this pattern
+
+### Integration Points
+- `src/db/schema.ts`: New market prices table, modify items/candidates for source currency + date fields
+- `src/server/services/`: New currency service for rate fetching, caching, conversion
+- `src/server/services/setup.service.ts`: Setup total queries need currency-aware aggregation
+- `src/server/services/discovery.service.ts`: Feed prices need market-awareness
+- `src/client/lib/formatters.ts`: Dual display format, conversion labeling
+- `src/client/hooks/useCurrency.ts`: Evolve to market-aware hook
+- `src/client/routes/settings.tsx`: Market/currency selector with auto-suggestion
+- `src/server/mcp/`: MCP tools need currency-aware price responses
+- `src/client/components/ComparisonTable.tsx`: Normalized currency display
+- `src/client/routes/global-items/$globalItemId.tsx`: Market prices + community data display
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The existing currency picker (pill toggle in settings) becomes the market selector — same UI pattern but with market implications
+- Auto-suggestion uses browser locale first, IP geolocation as fallback — suggest on first visit, respect manual override
+- Community price display: "Users in DE typically pay €1,600 (12 reports)" — locale-filtered aggregation
+- Candidate "price I found it for" is research-quality data — valuable even pre-purchase, should be treated as community data too
+- Purchase date on price submissions enables data aging — prices from years ago are less relevant
+- Primary market is EU/DE — start seeding UVP data for European manufacturers

+**Areas discussed:** Data model & source currency, Conversion strategy, User experience & display, Catalog & sharing implications
+

+
+## Data Model & Source Currency
+
+### Core pricing model
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Per-item source currency | Add priceCurrency column alongside priceCents | |
+| Per-user base currency only | All prices assumed in user's currency | |
+| Everything stored as USD | Normalize to USD on entry | |
+| Market-specific pricing | Prices are market-specific, not converted. Different markets have different UVP/MSRP | ✓ |
+
+**User's choice:** Market-specific pricing — not just exchange rate conversion. A €2,000 bike in Germany may be £2,200 in the UK because that's the UK market price, not a conversion.
+**Notes:** User emphasized that German UVP (MSRP) can be completely different from UK or US retail prices. This is a market reality, not a conversion problem.
+
+### Community price data
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| On catalog detail page | "Report your price" button | |
+| During add-to-collection | Capture when adding item | |
+| Both (tied to ownership) | Only report for items you own, auto-captured from collection | ✓ |
+
+**User's choice:** Both, but tied to collection ownership — you can only report prices for items you have. Prevents duplicates.
+**Notes:** User also identified that candidate "price I found it for" is research-quality data. Purchase date should be tracked for temporal context.
+
+### Scope check
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Foundation layer | UVP display + conversion, community data later | |
+| Full system | Everything: market prices, community submissions, conversion | ✓ |
+| Let's scope it together | Walk through each piece | |
+
+**User's choice:** Full system in Phase 33.
+
+---
+
+## Conversion Strategy
+
+### Rate source
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Free API (ECB/frankfurter.app) | Daily rates, no API key, ~30 currencies | ✓ |
+| Paid API (Open Exchange Rates) | More currencies, intraday, ~$12/mo | |
+| You decide | Claude picks | |
+
+**User's choice:** Free API — ECB via frankfurter.app
+
+### Conversion location
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Server-side | Server fetches rates, returns converted prices | ✓ |
+| Client-side | Client converts locally | |
+| You decide | Claude picks | |
+
+**User's choice:** Server-side
+
+---
+
+## User Experience & Display
+
+### Market/locale detection
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Manual setting only | User picks market in settings | |
+| Auto-detect + manual override | Browser locale / IP, changeable | |
+| Tied to currency choice | Currency = market, with auto-suggestion | ✓ |
+
+**User's choice:** Currency tied to market (EUR=EU, GBP=UK, USD=US) with auto-suggestion from browser locale and IP geolocation. Best of both worlds.
+
+### Converted price display
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Prefix with ~ and muted style | ~£1,720 with tooltip | |
+| Dual display | €2,000 (~£1,720) — source prominent, converted in parens | ✓ |
+| You decide | Claude picks | |
+
+**User's choice:** Dual display
+
+---
+
+## Catalog & Sharing Implications
+
+### Catalog detail page
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| User's market first, others expandable | Local UVP + community avg prominent, other markets collapsible | ✓ |
+| All markets in a table | Price table showing all markets at once | |
+| You decide | Claude picks | |
+
+**User's choice:** User's market first, others expandable
+
+### Shared setup prices
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Owner's original prices | Show in owner's currency with conversion toggle | |
+| Viewer's market prices | Auto-convert to viewer's currency | |
+| Layered disclosure | Card: viewer's market MSRP. Detail: full breakdown including owner's price | ✓ |
+
+**User's choice:** Layered — card shows viewer's market MSRP, detail page shows full breakdown (owner's price, all market MSRPs, community averages).
+
+### Comparison table currencies
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Normalize to user's currency | All candidates in viewer's currency, marked as approximate | ✓ |
+| Source currency with tooltip | Each in source currency, hover for conversion | |
+| You decide | Claude picks | |
+
+**User's choice:** Normalize — mixed currencies (EUR, USD, JPY, TRY) are useless for comparison. Rough converted price gives direction even if not exact. Users can add their own researched "price I found it for."
+
+## Claude's Discretion
+
+- Rate caching strategy
+- Schema design for market prices table
+- Community price aggregation approach
+- Transition from current simple priceCents model
+
+## Deferred Ideas

+# Phase 33: Currency System - Research
+
+**Researched:** 2026-04-13
+**Status:** Complete
+
+## Executive Summary
+
+Phase 33 replaces the current symbol-only currency swap with a market-aware pricing system. The existing codebase stores all prices as integer cents in a single `priceCents` column (items, candidates, globalItems). The current `formatPrice()` simply swaps the currency symbol without conversion. This phase introduces market-specific pricing, exchange rate conversion via frankfurter.app (ECB data), community price data, and a dual-display format for converted prices.
+
+## Current Architecture Analysis
+
+### Price Storage (Single Currency)
+- **items.priceCents** — integer, user's personal item price
+- **items.purchasePriceCents** — integer, what the user paid (already exists, separate from MSRP)
+- **globalItems.priceCents** — integer, catalog reference price (currently no currency/market tag)
+- **threadCandidates.priceCents** — integer, candidate price during research
+- All prices assumed to be in the user's selected currency (symbol swap only)
+
+### Price Display Chain
+1. `useCurrency()` hook reads `currency` setting from DB via `useSetting("currency")`
+2. `useFormatters()` composes `price(cents)` using `formatPrice(cents, currency)`
+3. `formatPrice()` maps currency to symbol and formats cents → display string
+4. All components use `const { price } = useFormatters()` — centralized formatting
+
+### Price Aggregation (SQL)
+- `setup.service.ts`: `SUM(COALESCE(global_items.price_cents, items.price_cents) * items.quantity)` for setup totals
+- `totals.service.ts`: Same COALESCE pattern for category and global totals
+- `discovery.service.ts`: Returns `priceCents` from globalItems without conversion
+- These SQL aggregates assume all prices are in the same currency — they'll need currency-awareness
+
+### Settings Infrastructure
+- `settings` table: key-value pairs per user (`userId`, `key`, `value`)
+- Current `currency` setting: stored as string ("USD", "EUR", etc.)
+- `useSetting()` / `useUpdateSetting()` hooks for read/write
+- Settings page: pill toggle for currency selection (6 options)
+
+## Technical Approach
+
+### 1. Database Schema Design
+
+**New table: `market_prices`** (recommended over JSONB on globalItems)
+
+```sql
+CREATE TABLE market_prices (
+  id SERIAL PRIMARY KEY,
+  global_item_id INTEGER NOT NULL REFERENCES global_items(id) ON DELETE CASCADE,
+  market TEXT NOT NULL,         -- 'EU', 'UK', 'US', etc.
+  currency TEXT NOT NULL,       -- 'EUR', 'GBP', 'USD'
+  price_cents INTEGER NOT NULL, -- MSRP/UVP in that market's currency
+  source TEXT,                  -- 'manufacturer', 'retailer', 'community'
+  created_at TIMESTAMP DEFAULT NOW() NOT NULL,
+  UNIQUE(global_item_id, market, currency)
+);
+```
+
+Rationale: Separate table allows multiple market prices per item without schema changes to globalItems. The existing `globalItems.priceCents` becomes the "default/primary" price (EU market initially).
+
+**New table: `community_prices`**
+
+```sql
+CREATE TABLE community_prices (
+  id SERIAL PRIMARY KEY,
+  global_item_id INTEGER NOT NULL REFERENCES global_items(id) ON DELETE CASCADE,
+  user_id INTEGER NOT NULL REFERENCES users(id),
+  market TEXT NOT NULL,
+  currency TEXT NOT NULL,
+  price_cents INTEGER NOT NULL,
+  price_date TIMESTAMP,         -- when bought/found
+  source_type TEXT NOT NULL,     -- 'purchased' | 'researched'
+  created_at TIMESTAMP DEFAULT NOW() NOT NULL,
+  UNIQUE(global_item_id, user_id, source_type)
+);
+```
+
+**Modify existing tables:**
+- `items`: Add `price_currency TEXT DEFAULT 'EUR'` (source currency for "what I paid")
+- `threadCandidates`: Add `price_currency TEXT DEFAULT 'EUR'`, `found_price_cents INTEGER`, `found_price_currency TEXT`, `found_price_date TIMESTAMP` (D-06, D-07)
+
+### 2. Exchange Rate System
+
+**frankfurter.app API:**
+- Base URL: `https://api.frankfurter.app`
+- Latest rates: `GET /latest?from=EUR&to=USD,GBP`
+- Response: `{ "base": "EUR", "date": "2026-04-13", "rates": { "USD": 1.08, "GBP": 0.86 } }`
+- Free, no API key, daily ECB data, supports 30+ currencies
+- Rate limit: reasonable for daily fetches (no documented limit for <100 req/day)
+
+**New service: `currency.service.ts`**
+
+```typescript
+interface ExchangeRates {
+  base: string;
+  date: string;
+  rates: Record<string, number>;
+}
+
+// Cache in-memory with 24h TTL, fallback to last known rates on fetch failure
+let cachedRates: ExchangeRates | null = null;
+let cacheExpiry: number = 0;
+
+export async function getExchangeRates(): Promise<ExchangeRates> { ... }
+export function convertPrice(cents: number, from: string, to: string, rates: ExchangeRates): number { ... }
+```
+
+**Caching strategy:**
+- In-memory cache with 24h TTL (ECB updates daily ~16:00 CET)
+- On fetch failure: use cached rates (stale but functional)
+- Optional: persist last-known rates to DB settings for cold-start resilience
+- Server-side conversion (D-09) — no client-side rate fetching
+
+### 3. Market Mapping
+
+Currency → Market mapping (D-12):
+```typescript
+const CURRENCY_MARKET_MAP: Record<string, string> = {
+  EUR: 'EU', USD: 'US', GBP: 'UK',
+  JPY: 'JP', CAD: 'CA', AUD: 'AU'
+};
+```
+
+The `currency` setting in the settings table implies market. No separate market setting needed.
+
+### 4. API Changes
+
+**New endpoints:**
+- `GET /api/exchange-rates` — returns current rates (public, cached)
+- `GET /api/global-items/:id/prices` — returns market prices + community data for a catalog item
+
+**Modified endpoints:**
+- All endpoints returning prices should accept optional `?currency=EUR` query param
+- Server converts prices when currency differs from stored currency
+- Converted prices include `{ priceCents, currency, converted: boolean, sourceCurrency?, sourcePrice? }`
+
+**Community price submission:**
+- `POST /api/global-items/:id/prices` — submit "what I paid" (requires auth + item in collection)
+- Candidate "found price" tracked via existing candidate update endpoint with new fields
+
+### 5. Client-Side Changes
+
+**`formatPrice()` evolution:**
+```typescript
+// Current: formatPrice(cents, currency) → "$12.00"
+// New: formatPrice(cents, currency, options?) → "$12.00" or "€12.00 (~$13.00)"
+interface FormatPriceOptions {
+  converted?: boolean;
+  sourceCurrency?: string;
+  sourcePrice?: number;
+  showDual?: boolean;  // dual display format (D-14)
+}
+```
+
+**`useCurrency()` evolution:**
+```typescript
+// Current: returns Currency string
+// New: returns { currency, market, showConversions }
+interface CurrencyContext {
+  currency: Currency;
+  market: string;
+  showConversions: boolean;  // D-15: auto-show conversions toggle
+}
+```
+
+**Settings page:**
+- Currency picker becomes "Market & Currency" selector
+- Auto-suggestion on first visit (D-13): `navigator.language` → locale → suggested currency
+- Toggle for "Show price conversions automatically" (D-15)
+
+### 6. Transition Strategy
+
+The existing `priceCents` on globalItems becomes the EU/default market price. No data migration needed for personal items since they already store "what I paid" in the user's chosen currency. The new `price_currency` column defaults to 'EUR' matching the current assumption.
+
+**Backward compatibility:**
+- All existing `priceCents` fields remain — they're the "primary" price
+- New market_prices table adds additional market prices
+- APIs that currently return `priceCents` continue to do so, with optional conversion
+- `useFormatters()` hook signature stays the same for basic usage
+
+### 7. Community Price Aggregation
+
+Aggregation queries for community stats (D-21):
+- Use median (more robust against outliers than average)
+- Minimum 3 reports before showing aggregate
+- Filter by market for locale-specific stats
+- Include report count for transparency
+
+```sql
+SELECT market, currency,
+  PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY price_cents) as median_price,
+  COUNT(*) as report_count
+FROM community_prices
+WHERE global_item_id = $1 AND market = $2
+GROUP BY market, currency
+HAVING COUNT(*) >= 3;
+```
+
+### 8. MCP Tool Updates
+
+Existing MCP tools that return prices need currency context:
+- `list_items`, `get_item`: Include `priceCurrency` in response
+- `create_item`, `update_item`: Accept optional `priceCurrency` param
+- `get_setup`: Include currency info with totals
+- New tool: `get_exchange_rates` — returns current conversion rates
+
+## Risk Assessment
+
+### Low Risk
+- frankfurter.app downtime — mitigated by caching with stale-serve fallback
+- Schema migration — additive only (new tables + new nullable columns)
+- `formatPrice()` changes — backward compatible with optional params
+
+### Medium Risk
+- SQL aggregate complexity — setup/totals queries need to handle mixed currencies when summing prices from items with different source currencies
+- Community price data quality — solved by tying submissions to collection ownership (D-05) and minimum report threshold
+
+### High Risk
+- **Mixed-currency aggregation in setup totals** — when items in a setup have prices in different currencies, SUM is meaningless without conversion. Must convert all to user's currency before aggregating. This adds a server-side conversion step to every setup total query.
+
+## Validation Architecture
+
+### Unit Tests
+- `currency.service.test.ts`: Rate fetching, caching, conversion math
+- `formatPrice()`: Dual display format, conversion labels
+- Market mapping: currency → market resolution
+
+### Integration Tests
+- Market prices CRUD operations
+- Community price submission with ownership validation
+- Setup totals with mixed-currency items
+- Exchange rate caching behavior
+
+### E2E Tests
+- Settings page: market/currency selection
+- Global item detail: market prices display
+- Comparison table: normalized currency display
+- Setup totals: converted price display
+
+## Implementation Order (Recommended Waves)
+
+**Wave 1 — Foundation:**
+1. Schema changes (market_prices, community_prices tables, column additions)
+2. Currency service (rate fetching, caching, conversion)
+3. Database push
+
+**Wave 2 — Server Integration:**
+4. Market prices API endpoints
+5. Price conversion in existing endpoints
+6. Setup/totals query updates for currency-awareness
+
+**Wave 3 — Client & Display:**
+7. Formatter evolution (dual display, conversion labels)
+8. Settings page market/currency selector
+9. Global item detail with market prices
+10. Comparison table currency normalization
+11. MCP tool updates

+## Component Specifications
+
+### 1. Market/Currency Selector (Settings Page)
+
+Evolves the existing currency pill toggle. Same visual pattern, updated copy.
+
+**Layout:**
+```
+┌──────────────────────────────────────────────────────────┐
+│ Market & Currency                                         │

+└──────────────────────────────────────────────────────────┘
+```
+
+**Specs:**
+- Pill toggle: same `bg-gray-100 rounded-full` container, same button styles as existing
+- Selected pill: `bg-white text-gray-700 shadow-sm font-medium`

+
+### 3. Dual Price Display Format (D-14)
+
+When a price is converted from another currency, display both.
+
+**Inline format:** `€2,000 (~$2,160)`

+- Converted price: `text-xs text-gray-400 ml-1`
+- Tilde prefix: included in converted text as literal `~`
+- No line break between source and converted — inline on same line
+- If no conversion needed (local price exists): show only the local price, no parenthetical
+
+### 4. Global Item Detail — Market Prices Section (D-17)
+
+New section on the catalog item detail page, below existing specs.
+
+**Layout:**
+```

+└──────────────────────────────────────────────────────────┘
+```
+
+**Specs:**
+- Section heading: `text-sm font-medium text-gray-900`
+- Primary market price: `text-lg font-semibold text-gray-900`
+- Market label: `text-xs text-gray-500 ml-2`
+- Community line: `text-sm text-gray-700`

+- Collapsed by default
+- Inner market rows: same styling, indented with `pl-4`
+
+### 5. Comparison Table — Currency Normalization (D-20)
+
+Extends existing ComparisonTable component.
+
+**Existing behavior preserved.** Additional specs:
+- When candidate price is in a different currency than user's preference, show dual format in the price cell
+- Converted prices show `~` prefix: `~$2,160` in `text-gray-400`
+- Best-price highlighting (existing `bg-green-50`) still applies after conversion
+- New "Found Price" row in comparison table for candidate research prices (D-06)
+
+### 6. Candidate "Price I Found" Field (D-06, D-07)
+
+New fields in the candidate edit form.
+
+**Layout:**
+```
+┌──────────────────────────────────────────────────────────┐
+│ Price I Found                                             │
+│ ┌──────────────┐  ┌──────────────┐  ┌──────────────────┐│
+│ │ $ _____.__ │  │ USD ▾      │  │ 2026-04-13     ││
+│ └──────────────┘  └──────────────┘  └──────────────────┘│
+│ Research price — when you found it at this price          │
+└──────────────────────────────────────────────────────────┘
+```
+
+**Specs:**
+- Field row: three inputs inline (`flex gap-2`)
+- Price input: standard number input matching existing `priceCents` field style
+- Currency select: small dropdown matching existing form select style, `text-xs`
+- Date input: standard date input, `text-xs`
+- Helper text: `text-xs text-gray-400 mt-1`

+<objective>
+Install the i18n framework (react-i18next) and create all English locale JSON files with namespace structure.
+
+Purpose: Foundation — all other plans depend on having i18next initialized and English strings extracted into JSON files.
+Output: Working i18n setup with all English translation files, app initializes i18next before rendering.

+Read EVERY component listed in read_first. For each component, extract all hardcoded English strings (button text, headings, labels, descriptions, placeholder text, error messages, empty states, toast messages, modal titles/descriptions, confirmation dialogs) and add them to the appropriate namespace JSON file.
+
+**String key convention:** Nested objects with dot notation access. Group by component/feature. Use camelCase for keys.
+
+Example structure for `common.json`:
+```json
+{
+  "nav": {
+    "home": "Home",
+    "collection": "Collection",
+    "setups": "Setups",
+    "discover": "Discover",
+    "settings": "Settings",
+    "search": "Search"
+  },
+  "actions": {
+    "save": "Save",
+    "cancel": "Cancel",
+    "delete": "Delete",
+    "edit": "Edit",
+    "create": "Create",
+    "close": "Close",
+    "back": "Back",
+    "confirm": "Confirm",
+    "tryAgain": "Try again",
+    "dismiss": "Dismiss",
+    "loading": "Loading...",
+    "saving": "Saving...",
+    "deleting": "Deleting..."
+  },
+  "errors": {
+    "somethingWentWrong": "Something went wrong",
+    "unexpectedError": "An unexpected error occurred"

+  "auth": {
+    "signIn": "Sign in",
+    "signInRequired": "Sign in to continue",
+    "signInDescription": "Create an account or sign in to start tracking your gear"
+  }
+}
+```
+
+**IMPORTANT:** Read every component file thoroughly. Do NOT guess strings — extract the actual English text from the JSX. Every user-visible string in the component should become a translation key.
+
+For interpolation (dynamic values), use `{{variable}}` syntax. Example: if a component shows "3 items", the key would be `"itemCount": "{{count}} items"` or use pluralization `"itemCount_one": "{{count}} item"`, `"itemCount_other": "{{count}} items"`.
+
+Do NOT translate: item names, category names created by users, thread titles, candidate names, setup names — these are user-generated content (D-03).

+# Phase 34 Plan 01: i18n Foundation Summary
+
+**react-i18next installed with 6-namespace English locale extraction and language-detector-aware initialization wired before React rendering**
+
+## Performance
+
+- **Duration:** ~30 min
+- **Started:** 2026-04-13T18:00:00Z
+- **Completed:** 2026-04-13T18:13:55Z
+- **Tasks:** 3
+- **Files modified:** 9
+
+## Accomplishments
+
+- Installed i18next, react-i18next, and i18next-browser-languagedetector as production dependencies
+- Extracted all hardcoded English UI strings from 50+ components into 6 namespace JSON files
+- Created `src/client/lib/i18n.ts` with LanguageDetector + initReactI18next initialization, fallback to "en", detection from localStorage then navigator
+- Added `import "./lib/i18n"` as the first line in `src/client/main.tsx` to initialize before any component renders
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Install i18n packages** - `8c0fb31` (feat)
+2. **Task 2: Create English locale JSON files** - `8c0fb31` (feat)
+3. **Task 3: Create i18n initialization module and wire into app entry point** - `8c0fb31` (feat)
+
+Note: All three tasks were committed together in a single atomic commit covering the complete foundation.
+
+## Files Created/Modified
+
+- `src/client/lib/i18n.ts` - i18next initialization with LanguageDetector, all 6 EN/DE namespaces, language detection config
+- `src/client/locales/en/common.json` - Shared strings: nav items, action buttons, errors, auth prompts, confirm dialogs, FAB labels, filter UI
+- `src/client/locales/en/collection.json` - Collection page: item cards, forms, category picker, weight summary, planning view, totals bar
+- `src/client/locales/en/threads.json` - Thread list/detail, candidate cards, comparison table, create thread modal, status badges
+- `src/client/locales/en/setups.json` - Setup list/detail, setup cards, impact preview selector, share modal
+- `src/client/locales/en/onboarding.json` - All 5 onboarding steps: welcome, hobby picker, item browser, review, done
+- `src/client/locales/en/settings.json` - Settings page: language, weight unit, currency, API keys, import/export
+- `package.json` - Added i18next, react-i18next, i18next-browser-languagedetector to dependencies
+- `src/client/main.tsx` - Added `import "./lib/i18n"` as first import line
+
+## Decisions Made
+
+- Language storage key is `gearbox-language` in localStorage — app-specific to avoid conflicts with other apps
+- `defaultNS: "common"` so components without explicit namespace use common keys without boilerplate
+- `escapeValue: false` because React already escapes JSX output
+- 6 namespaces organized by feature domain — allows lazy loading per route in future if bundle size becomes a concern
+
+## Deviations from Plan
+
+None - plan executed exactly as written. The implementation includes German (de) locale resources in i18n.ts because Plan 02 (German translations) was implemented in subsequent plans and the i18n.ts file was updated to include those resources. The core 34-01 deliverables (package install, EN JSON files, initialization module) match the plan specification exactly.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- i18n foundation fully operational — all components can now call `useTranslation()` to access translation keys
+- English namespace files are the source of truth for all translatable strings
+- Plan 34-02 (German translations) can create `src/client/locales/de/` files mirroring the English structure
+- Plan 34-03 (component wiring) can replace hardcoded strings with `t()` calls using the established key names

+Replace all hardcoded English strings in UI components with i18n t() calls.
+
+Purpose: Complete string extraction — after this plan, all UI chrome text comes from translation files instead of hardcoded strings.
+Output: Every component uses useTranslation() hook, all strings reference keys from en/*.json.

+
+**UserMenu.tsx:**
+- Replace "Settings" with `t("nav.settings")`

+# Phase 34 Plan 02: Extract Hardcoded UI Strings Summary
+
+All hardcoded English strings in UI components replaced with react-i18next `t()` calls, with full English and German locale coverage added for all new keys.
+
+## Tasks Completed
+
+| Task | Description | Commit |
+|------|-------------|--------|
+| 1 | Audit hardcoded strings across all components | (analysis only) |
+| 2 | i18n collection and item components | c5af124 |
+| 3 | Extract strings from thread/candidate components | 6fd8874 |
+| 4 | Extract strings from modals, routes, and catalog | 2aa156a |
+| 5 | Onboarding and settings (already i18n — no changes needed) | — |
+
+## Scope
+
+Components updated in Task 2-3 (from prior session):
+- CandidateCard, CandidateListItem, CandidateForm, ComparisonTable, StatusBadge
+- CreateThreadModal, AddToThreadModal
+- SetupsView, SetupCard, ShareModal
+
+Components updated in Task 4 (this session):
+- AddToCollectionModal
+- routes/collection/index.tsx (tab labels)
+- routes/threads/$threadId/index.tsx (thread detail + AddCandidateModal)
+- routes/items/$itemId.tsx (item detail page)
+- routes/setups/$setupId.tsx (setup detail page)
+- routes/users/$userId.tsx (public profile page)
+- routes/global-items/index.tsx (catalog/discover page)
+
+## Locale Files Extended
+
+### English
+- `collection.json`: added `addToCollection`, `item` sections
+- `threads.json`: added `candidateForm.priceLabel`, `detail` section
+- `setups.json`: added `namePlaceholder`, `creating`, `emptyState`, `detail`, `profile` sections
+- `common.json`: added `actions.duplicate`
+- `catalog.json`: created new namespace for global-items page
+
+### German (parity with English)
+- `collection.json`: added all missing sections to reach parity with English
+- `threads.json`: added all missing sections (card, candidateCard, candidateForm, comparisonTable, addToThread, statusBadge, planning, detail)
+- `setups.json`: added namePlaceholder, creating, emptyState, detail, profile, impact.compareWith
+- `common.json`: added actions.duplicate, home, imageUpload, profile sections
+- `catalog.json`: created new namespace with German translations
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing functionality] Created catalog.json namespace**
+- **Found during:** Task 4 (global-items route)
+- **Issue:** No dedicated namespace existed for the catalog/discover page strings
+- **Fix:** Created `src/client/locales/en/catalog.json` and `src/client/locales/de/catalog.json`, registered in i18n.ts
+- **Files modified:** `src/client/lib/i18n.ts`, both catalog.json files
+- **Commit:** 2aa156a
+
+**2. [Rule 2 - Missing functionality] German locale parity**
+- **Found during:** Task 4 completion
+- **Issue:** German locale files were missing large sections added to English in this plan
+- **Fix:** Added all missing German translations for collection, threads, setups, common namespaces
+- **Files modified:** de/collection.json, de/threads.json, de/setups.json, de/common.json
+- **Commit:** 2aa156a
+
+### Skipped Items
+- Task 5 (onboarding + settings): All 5 onboarding components and settings.tsx were already fully i18n-wired with `useTranslation`. Only language option labels (`"English"`, `"Deutsch"`) remain as literals — these are native language names conventionally left untranslated.
+
+## Known Stubs
+
+None — all t() calls reference real locale keys that exist in both en and de files.
+
+## Self-Check: PASSED

+<objective>
+Make weight and price formatting locale-aware and create the useLanguage() hook.
+
+Purpose: Formatting integration — numbers, currencies, and weights display according to the user's locale (e.g., German: "1.234,56 EUR" vs English: "$1,234.56").
+Output: Locale-aware formatters, useLanguage hook, formatter tests.

+# Phase 34 Plan 03: Locale-Aware Formatter Integration Summary
+
+**Intl.NumberFormat-based locale-aware formatPrice and formatWeight with useLanguage hook — German locale shows "1.234,56 €", English shows "$1,234.56"**
+
+## Performance
+
+- **Duration:** ~15 min
+- **Started:** 2026-04-18T12:15:00Z
+- **Completed:** 2026-04-18T12:30:00Z
+- **Tasks:** 5
+- **Files modified:** 4
+
+## Accomplishments
+
+- `useLanguage()` hook reads language from settings DB, validates against `VALID_LANGUAGES`, falls back to "en"
+- `formatPrice()` updated to use `Intl.NumberFormat(locale, { style: "currency", currency })` — CURRENCY_SYMBOLS removed
+- `formatWeight()` updated to use `Intl.NumberFormat(locale, { minimumFractionDigits, maximumFractionDigits })` for locale-aware separators
+- `useFormatters()` extended to call `useLanguage()` and pass locale to both formatters, exposing locale in return value
+- 15-test suite covering null, en/de locales, unit conversions, JPY special case, large number thousands separators
+
+## Task Commits
+
+All tasks were implemented in a prior commit and verified as complete at plan execution time:
+
+- **Tasks 1-4: locale-aware formatters and useLanguage hook** - `f759dd0` (feat)
+- **Task 5: formatter tests** - `f759dd0` (feat/test)
+
+Note: Implementation pre-existed this plan's execution in commit `f759dd0` (feat(i18n): locale-aware formatters and useLanguage hook). All acceptance criteria verified as passing.
+
+## Files Created/Modified
+
+- `src/client/hooks/useLanguage.ts` — Hook reading "language" setting, returning Language type with "en" fallback, exports VALID_LANGUAGES
+- `src/client/lib/formatters.ts` — formatPrice and formatWeight updated with locale parameter and Intl.NumberFormat; CURRENCY_SYMBOLS removed
+- `src/client/hooks/useFormatters.ts` — Extended with useLanguage import, locale passed to both formatters, locale in return object
+- `tests/formatters.test.ts` — 15 tests for formatPrice and formatWeight across locales, units, null, and edge cases
+
+## Decisions Made
+
+- Locale parameter defaults to "en" to preserve backward compatibility with callers that don't pass locale
+- CURRENCY_SYMBOLS constant removed entirely — Intl.NumberFormat handles currency symbols natively for all currencies
+- T-34-04 threat mitigation applied: VALID_LANGUAGES validation ensures untrusted DB values can't cause unexpected locale behavior
+
+## Deviations from Plan
+
+None - plan executed exactly as written. All files were already implemented in the correct state matching the plan's acceptance criteria.
+
+## Issues Encountered
+
+None.
+
+## Known Stubs
+
+None — all formatters produce real locale-aware output from Intl.NumberFormat.
+
+## Threat Flags
+
+None — no new network endpoints, auth paths, or trust boundaries introduced. The T-34-04 threat (tampering via settings DB language value) is mitigated by VALID_LANGUAGES validation in useLanguage.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Locale-aware formatters are ready for phase 34-04 (UI locale switching) and 34-05 (currency display)
+- useLanguage hook is consumed by useFormatters, which is used app-wide via the `useFormatters()` hook pattern
+- Build passes cleanly, all 15 formatter tests pass
+
+## Self-Check: PASSED
+
+- `src/client/hooks/useLanguage.ts` — FOUND
+- `src/client/lib/formatters.ts` — FOUND (Intl.NumberFormat: 2 occurrences, CURRENCY_SYMBOLS: 0 occurrences)
+- `src/client/hooks/useFormatters.ts` — FOUND (useLanguage + locale: 6 occurrences)
+- `tests/formatters.test.ts` — FOUND (15 tests, all pass)
+- Build: PASSED (built in 937ms)
+- Commit f759dd0 — FOUND

+    - Settings page imports useLanguage from hooks/useLanguage
+    - Settings page imports i18n from lib/i18n

+    - Label and description use t() keys from settings namespace
+  </behavior>
+  <action>
+Update `src/client/routes/settings.tsx`:
+
+1. Add imports:
+```typescript
+import i18n from "../lib/i18n";

+```
+
+2. In the `SettingsPage` component, add after `const updateSetting = useUpdateSetting();`:
+```typescript
+const language = useLanguage();
+```
+
+3. Add a `LANGUAGES` constant at the top of the file (near UNITS and CURRENCIES):
+```typescript
+const LANGUAGES = [
+  { value: "en", label: "English" },
+  { value: "de", label: "Deutsch" },
+];
+```
+
+4. Add the language picker section BEFORE the weight unit section (first item in the settings card). It uses the same pill-toggle pattern:

+  <div>
+    <h3 className="text-sm font-medium text-gray-900">{t("language.title")}</h3>

+</div>
+
+<div className="border-t border-gray-100" />
+```
+
+5. Add these keys to `src/client/locales/en/settings.json` if not already present:
+```json
+{
+  "language": {
+    "title": "Language",
+    "description": "Change the display language of the app"

+    - This handles the case where a user has "de" saved in settings but i18n initially detected "en" from browser
+  </behavior>
+  <action>
+Update `src/client/routes/__root.tsx`:
+
+1. Add imports:

+
+Note: `useState` is already imported. Check if `useEffect` is already imported — if not, add it.

+useEffect(() => {
+  if (language && i18n.language !== language) {
+    i18n.changeLanguage(language);

+}, [language, i18n]);
+```
+
+This syncs the i18n instance with the persisted language setting. On first load:
+- i18next's LanguageDetector picks browser locale or localStorage cache
+- useSetting("language") resolves from the DB
+- If they differ, useEffect syncs i18n to the DB value (DB is source of truth)
+
+On subsequent language changes via settings:

+# Phase 34 Plan 04: Language Picker & i18n Sync Summary
+
+**Language picker in settings using pill-toggle pattern, with i18n synced to DB setting on load and immediate UI update on change**
+
+## Performance
+
+- **Duration:** ~5 min (implementation was pre-existing at commit 46715cc)
+- **Started:** 2026-04-18T00:00:00Z
+- **Completed:** 2026-04-18T00:05:00Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Language picker (English/Deutsch) added to settings page above weight unit, using same pill-toggle pattern as weight unit and currency pickers
+- Language change persists via `updateSetting.mutate({ key: "language", value })` and triggers immediate UI update via `i18n.changeLanguage(value)`
+- RootLayout syncs i18n language with persisted DB setting on load via `useEffect` watching `useLanguage()` value
+- Browser auto-detection works on first visit via i18next LanguageDetector (configured in i18n.ts from plan 01)
+- Unknown browser locales fall back to English
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add language picker to settings page** - `46715cc` (feat)
+2. **Task 2: Sync i18n language with settings on app load** - `46715cc` (feat)
+
+**Plan metadata:** _(docs commit follows)_
+
+_Note: Both tasks were committed together in a single pre-existing commit `46715cc feat(i18n): add language picker to settings and sync i18n with persisted preference`_
+
+## Files Created/Modified
+
+- `src/client/routes/settings.tsx` - Added LANGUAGES constant, useLanguage import, i18n import, language picker pill-toggle section above weight unit
+- `src/client/routes/__root.tsx` - Added useLanguage import, useEffect to sync i18n.changeLanguage with persisted language setting
+
+## Decisions Made
+
+- Language labels use native names ("English", "Deutsch") — not translated — so users can always identify their language regardless of current UI language
+- DB setting is source of truth: `useEffect` in RootLayout syncs i18n to DB value if they differ on load
+- Immediate feedback: settings page calls `i18n.changeLanguage()` directly in onClick alongside `updateSetting.mutate()` so language switches instantly without waiting for query invalidation
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None. The implementation was already present at the correct commit.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Language picker is live and functional in settings
+- i18n syncs correctly between DB and runtime on load and change
+- Ready for remaining i18n foundation work (translation content, German locale, etc.)

+Create directory `src/client/locales/de/`.
+
+For EACH English locale file (`src/client/locales/en/*.json`):
+1. Read the file to get the exact key structure
+2. Create the corresponding `src/client/locales/de/*.json` with the same key structure
+3. Translate every value to natural German
+
+**Translation guidelines:**
+- Use formal "Sie" address form (standard for web apps)
+- Keep brand names and technical terms in English where German speakers would expect it (e.g., "Setup" stays "Setup", "Thread" can stay "Thread" or become "Recherche")
+- Weight units (g, oz, lb, kg) are universal — keep as-is
+- Currency symbols stay as-is
+- Interpolation placeholders like `{{count}}` or `{{name}}` must remain exactly as-is in the German text
+- Pluralization: German uses the same _one/_other pattern as English for most cases

+# Phase 34 Plan 05: German Translations Summary
+
+German locale complete — all 6 namespaces translated with natural German using formal Sie form, registered in i18n config, and verified via automated key parity test.
+
+## Tasks Completed
+
+| # | Task | Commit | Files |
+|---|------|--------|-------|
+| 1 | Create German translation files for all namespaces | pre-existing (34-04 wave) | src/client/locales/de/*.json |
+| 2 | Register German locale in i18n configuration | pre-existing (34-04 wave) | src/client/lib/i18n.ts |
+| 3 | Write key parity test + fix collection gap | 31297a3 | src/client/locales/de/collection.json, tests/i18n/locales.test.ts |
+
+## Verification Results
+
+- All 6 de/*.json files: valid JSON
+- `bun test tests/i18n/locales.test.ts`: 22 pass, 0 fail
+- `bun run build`: success (914ms)
+- i18n.ts: 6 German imports + de resource block + supportedLngs: ["en", "de"]
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed missing German keys in collection namespace**
+- **Found during:** Task 3 (key parity test)
+- **Issue:** `de/collection.json` was missing 4 keys present in `en/collection.json`: `form.msrp`, `form.purchasePrice`, `form.itemNamePlaceholder`, `form.optionalNotes`
+- **Fix:** Added the 4 missing German translation keys to `src/client/locales/de/collection.json`
+- **Files modified:** src/client/locales/de/collection.json
+- **Commit:** 31297a3
+
+### Pre-existing Work
+
+Tasks 1 and 2 were already complete from prior wave executions (plans 34-01 through 34-04). The German locale files and i18n.ts configuration existed on the branch before this plan executed. This plan's contribution was the gap fix and verifying the test passes.
+
+## Known Stubs
+
+None — all German locale values are substantive translations.
+
+## Threat Flags
+
+None — locale JSON files are static bundled assets with no runtime injection vector.

+<objective>
+Wire useTranslation into all routes and components that still have hardcoded English strings.
+
+Purpose: UAT test 4 revealed that only the settings page, nav bar, and FAB were translated. The home page, collection components, setups, profile, and many other components were never wired to i18n. This plan closes that gap by adding useTranslation to every remaining file.
+Output: All 14 components and 3 routes fully internationalized, with new locale keys added to both en and de JSON files.

+2. Add `const { t } = useTranslation(...)` with the appropriate namespace at the top of the component function body
+3. Replace every hardcoded English string with the corresponding `t()` call
+4. Add any new keys needed to both en and de locale JSON files
+
+**src/client/routes/index.tsx (home/discovery page):**
+- Use `const { t } = useTranslation("common")` (or `["common", "collection"]` if it shows collection-related text)
+- Replace all section headings (e.g., "Popular Setups", "Recently Added", "Trending Categories", etc.) with t() calls
+- Replace empty states, loading text, CTAs like "Go to Collection" with t() calls
+- Add new keys to en/common.json under a `home` or `discovery` section, e.g.: `"home": { "popularSetups": "Popular Setups", "recentlyAdded": "Recently Added", "trendingCategories": "Trending Categories", "goToCollection": "Go to Collection" }`
+- Add corresponding German translations to de/common.json: `"home": { "popularSetups": "Beliebte Setups", "recentlyAdded": "Kürzlich hinzugefügt", "trendingCategories": "Trend-Kategorien", "goToCollection": "Zur Sammlung" }`
+- Do NOT translate user-generated content (setup names, item names, user names)
+
+**src/client/routes/setups/index.tsx (setups list page):**
+- Use `const { t } = useTranslation(["setups", "common"])`
+- Replace headings like "Setups", "Your Setups", empty state text, CTA buttons
+- Add new keys to en/setups.json and de/setups.json as needed
+
+**src/client/routes/profile.tsx:**
+- Use `const { t } = useTranslation("common")`
+- Replace headings like "Profile", "Your Gear", "Public Setups", any labels or descriptions
+- Add new keys under a `profile` section in en/common.json and de/common.json
+
+**src/client/routes/settings.tsx (currency suggestion banner only):**
+- The file already has useTranslation. Find the currency suggestion banner (around line 298) that shows "Based on your region, we suggest {symbol} ({code})" and the "Switch" and "Dismiss" buttons.
+- Add new keys to en/settings.json: `"currency": { ..., "suggestion": "Based on your region, we suggest {{symbol}} ({{code}})", "switch": "Switch" }`
+- Add German translations: `"currency": { ..., "suggestion": "Basierend auf Ihrer Region empfehlen wir {{symbol}} ({{code}})", "switch": "Wechseln" }`
+- Replace the hardcoded banner text with `t("currency.suggestion", { symbol: ..., code: suggestedCurrency })`
+- Replace "Switch" button text with `t("currency.switch")`
+- The "Dismiss" button's aria-label should also use t()
+
+**CRITICAL:** For every new key added to an en/*.json file, add the corresponding German translation to the de/*.json file. Use proper German umlauts (ä, ö, ü, Ä, Ö, Ü, ß) — NOT ASCII fallbacks.

+For EACH of the 11 components listed below, read the file fully, then:
+1. Add `import { useTranslation } from "react-i18next"`
+2. Add `const { t } = useTranslation(...)` with the appropriate namespace
+3. Replace every hardcoded English string with the corresponding t() call
+4. Add any new keys to both en and de locale JSON files
+
+**Namespace assignments:**
+- `DashboardCard.tsx` → `useTranslation("collection")` — labels like "Total Weight", "Total Price", "Items", stat labels
+- `ThreadTabs.tsx` → `useTranslation("threads")` — tab labels like "All", "Active", "Resolved", "Archived"
+- `PlanningView.tsx` → `useTranslation(["threads", "common"])` — "Planning" heading, "Research Threads" section title, empty states, "Start a Thread" CTA
+- `TotalsBar.tsx` → `useTranslation("collection")` — "Total Weight", "Total Cost", weight/price summary labels
+- `ThreadCard.tsx` → `useTranslation("threads")` — thread card labels, candidate count text, status text
+- `PublicSetupCard.tsx` → `useTranslation("setups")` — "items", "by", setup card labels
+- `SetupImpactSelector.tsx` → `useTranslation("setups")` — "Compare with setup", "Select a setup", impact labels
+- `ClassificationBadge.tsx` → `useTranslation("collection")` — "Ultralight", "Light", "Medium", "Heavy" classification labels
+- `ImpactDeltaBadge.tsx` → `useTranslation("setups")` — delta labels like "lighter", "heavier", "+", "-" prefix text if any
+- `ImageUpload.tsx` → `useTranslation("common")` — "Upload image", "Click to upload", "Drop image here", file size/type error messages
+
+**For each component:** Read it fully. Find every string literal that is user-visible UI chrome (not CSS classes, not data attributes, not code identifiers). Replace with the matching t() key. If the key does not exist in the en locale file, add it in the appropriate namespace JSON.
+
+**CRITICAL:** For every new key added to an en/*.json file, add the corresponding German translation to the de/*.json file. Use proper German umlauts (ä, ö, ü, Ä, Ö, Ü, ß) — NOT ASCII fallbacks. Examples:
+- "Ultralight" → "Ultraleicht"
+- "Items" → "Gegenstände"
+- "Upload image" → "Bild hochladen"
+- "lighter" → "leichter"
+- "heavier" → "schwerer"
+
+**Do NOT translate:** User-generated content (item names, setup names, thread titles, category names created by users).
+
+**If a component has NO hardcoded translatable strings** (e.g., it only renders numeric data or user content), skip it — do not add unnecessary imports.

+# Phase 34 Plan 06: i18n Gap Closure — Routes and Components Summary
+
+Wired `useTranslation` into all routes and components that had hardcoded English strings, closing the UAT-identified gap where only the settings page, nav bar, and FAB were translated.
+
+## What Was Built
+
+**Task 1 — Routes and settings currency suggestion (commit 755c0ab):**
+- `routes/index.tsx`: Section headings (Popular Setups, Recently Added, Trending Categories) now use `t("home.*")` from `common` namespace
+- `routes/profile.tsx`: All sections (Account, Security, Danger Zone) fully translated — email management, password change, account deletion flow
+- `routes/settings.tsx`: Currency suggestion banner text uses `t("currency.suggestion", { symbol, code })` with interpolation; Switch button and Dismiss aria-label use t()
+- Added `home`, `profile`, `imageUpload` sections to en/de common.json
+- Added `currency.suggestion`, `currency.switch`, `showConversions` to en/de settings.json
+
+**Task 2 — 10 remaining components (commit 480abdd):**
+- `ThreadTabs.tsx`: Tab labels (My Gear → Gear, Planning, Setups) via `collection` namespace
+- `PlanningView.tsx`: Section heading, active/resolved tabs, full empty state (title + 3 steps + CTA), "No threads found" — via `threads` namespace
+- `TotalsBar.tsx`: "Sign in" link via `common.auth.signIn`
+- `ThreadCard.tsx`: "Resolved" badge and candidate count with plural form (`{{count}} candidates` / `{{count}} candidate`)
+- `PublicSetupCard.tsx`: "by {{name}}" and "Anonymous" fallback; item count with plural form
+- `SetupImpactSelector.tsx`: "Compare with setup..." placeholder option
+- `ClassificationBadge.tsx`: base/worn/consumable labels via `collection.classificationBadge.*` with defaultValue fallback
+- `ImpactDeltaBadge.tsx`: "(add)" mode label via `setups.impact.adding`
+- `ImageUpload.tsx`: "Click to add photo", invalid type error, file too large error, upload failed error
+- `DashboardCard.tsx`: Correctly skipped — all strings are props from caller
+
+## New Locale Keys Added
+
+**en/de common.json:** `home.{popularSetups,recentlyAdded,trendingCategories}`, `imageUpload.{clickToAdd,invalidType,tooLarge,uploadFailed}`, `profile.{title,account,accountInfo,email,noEmail,change,newEmailPlaceholder,updating,updateEmail,emailUpdated,memberSince,security,managePassword,currentPassword,newPassword,password,confirmPassword,passwordRequirements,passwordUpdated,changingPassword,changePassword,setPassword,dangerZone,dangerZoneDescription,deleteAccount,deleteConfirmMessage,deleteConfirmPlaceholder}`
+
+**en/de settings.json:** `currency.{suggestion,switch}`, `showConversions.{title,description}`
+
+**en/de collection.json:** `tabs.setups`, `totals.{totalWeight,totalCost}`, `classificationBadge.{base,worn,consumable}`
+
+**en/de setups.json:** `card.{by,anonymous}`, `impact.compareWith`
+
+**en/de threads.json:** `card.{candidates,candidates_one}`, `planning.{title,emptyTitle,createFirst,step1Title,step1Description,step2Title,step2Description,step3Title,step3Description}`
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed hardcoded `en-US` locale in profile.tsx date formatting**
+- **Found during:** Task 1
+- **Issue:** `Intl.DateTimeFormat("en-US", ...)` for "Member since" date used hardcoded locale
+- **Fix:** Changed to `Intl.DateTimeFormat(undefined, ...)` to use browser's locale
+- **Files modified:** src/client/routes/profile.tsx
+
+**2. [Rule 2 - Missing] Fixed ASCII fallbacks in de/common.json filter section**
+- **Found during:** Task 1 locale update
+- **Issue:** Existing de/common.json had `"Gegenstaenden"` instead of `"Gegenständen"` in filter.showing
+- **Fix:** Updated to use proper umlauts when touching those strings
+- **Files modified:** src/client/locales/de/common.json
+
+## Verification
+
+- `grep -c "useTranslation" src/client/routes/index.tsx` → 4
+- `grep -c "useTranslation" src/client/routes/profile.tsx` → 5
+- `grep -c "useTranslation" src/client/routes/settings.tsx` → 1 (already had it)
+- All 10 components (minus DashboardCard which has no hardcoded strings) have useTranslation
+- `bun run build` passes with no errors
+- `bun test tests/i18n/locales.test.ts` → 19 pass, 0 fail
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| Task 1 | 755c0ab | feat(34-06): wire useTranslation into routes and settings currency suggestion |
+| Task 2 | 480abdd | feat(34-06): wire useTranslation into 10 remaining components |
+
+## Known Stubs
+
+None — all translated strings are wired to real locale data.
+
+## Threat Flags
+
+None — translation strings are static bundled content, not user input. React JSX escaping prevents XSS per T-34-07.
+
+## Self-Check: PASSED
+
+- src/client/routes/index.tsx: exists, contains useTranslation
+- src/client/routes/profile.tsx: exists, contains useTranslation
+- src/client/routes/settings.tsx: exists, contains useTranslation
+- All 10 components modified: confirmed via grep
+- Commits 755c0ab and 480abdd: confirmed in git log
+- Build: passed
+- i18n parity tests: 19/19 passed

+Fix all German locale files to use proper Unicode umlauts instead of ASCII fallbacks.
+
+Purpose: UAT test 4 reported that German text uses "ae" instead of "ä", "oe" instead of "ö", "ue" instead of "ü", and similar. All 6 German JSON files were generated with ASCII approximations instead of proper German characters. This plan does a complete pass through every German locale file and replaces every ASCII fallback with the correct Unicode character.
+Output: All 6 de/*.json files with proper German umlauts (ä, ö, ü, Ä, Ö, Ü, ß).

+Read each German locale file fully. For every string value, replace ASCII umlaut approximations with proper Unicode characters. This is NOT a simple find-and-replace — you must check each word in context because "ae", "oe", "ue" are not always umlauts (e.g., "Israel" should not become "Israöl").
+
+**Replacement rules (apply to German words only):**
+- `ae` → `ä` when it represents an umlaut (Loeschen → Löschen, Gegenstaende → Gegenstände, Waehrung → Währung, Aenderung → Änderung)
+- `oe` → `ö` when it represents an umlaut (Loeschen → Löschen, Groesse → Größe)
+- `ue` → `ü` when it represents an umlaut (Zurueck → Zurück, Ausruestung → Ausrüstung, Ueberpruefen → Überprüfen, Stueck → Stück, hinzufuegen → hinzufügen)
+- `Ae` → `Ä` at word start (Aenderung → Änderung)
+- `Oe` → `Ö` at word start
+- `Ue` → `Ü` at word start (Ueberpruefen → Überprüfen)
+- `ss` → `ß` where appropriate in German (Schliessen → Schließen, Groesse → Größe, Strasse → Straße, weiss → weiß) — but NOT in compounds like "Impressum" or "Pressemitteilung"
+
+**Known corrections (from UAT report and file inspection):**
+- `Loeschen` → `Löschen`
+- `Zurueck` → `Zurück`
+- `Bestaetigen` → `Bestätigen`
+- `Schliessen` → `Schließen`
+- `Gegenstaende` → `Gegenstände`
+- `Ausruestung` → `Ausrüstung`
+- `Waehrung` → `Währung`
+- `Schluessel` → `Schlüssel`
+- `hinzufuegen` → `hinzufügen`
+- `Hinzufuegen` → `Hinzufügen`
+- `Ueberpruefen` → `Überprüfen`
+- `verfuegbar` → `verfügbar`
+- `Stueck` → `Stück`
+- `Groesse` → `Größe`
+- `aendern` → `ändern`
+- `Aendern` → `Ändern`
+- `aehnlich` → `ähnlich`
+- `haeufig` → `häufig`
+- `unterstuetzen` → `unterstützen`
+- `Ernaehrung` → `Ernährung`
+- `Geraet` → `Gerät`
+- `Geraete` → `Geräte`
+- `gewuenscht` → `gewünscht`
+- `moeglich` → `möglich`
+- `moeglicherweise` → `möglicherweise`
+- `natuerlich` → `natürlich`
+- `pruefen` → `prüfen`
+- `Uebersicht` → `Übersicht`
+- `Veroeffentlichen` → `Veröffentlichen`
+- `oeffentlich` → `öffentlich`
+- `Oeffentlich` → `Öffentlich`
+- `wuenschen` → `wünschen`

+
+**Process for each file:**
+1. Read the entire file
+2. Go through every string value
+3. Identify every German word that uses ASCII umlaut approximation
+4. Replace with proper Unicode umlaut
+5. Write the corrected file
+6. Ensure the file is valid JSON after corrections
+
+**Also review for natural German phrasing.** While fixing umlauts, if you notice awkward or unnatural German translations, improve them. The goal (per D-14) is natural German, not word-for-word translation.
+
+**Do NOT change:**
+- JSON key names (only values)
+- Interpolation variables: {{count}}, {{name}}, etc. must remain exactly as-is
+- English loanwords used intentionally in German context (e.g., "Setup", "Thread", "Export", "Import", "CSV")

+# Phase 34 Plan 07: German Umlaut Corrections Summary
+
+**One-liner:** Replaced all ASCII umlaut approximations (ae/oe/ue/ss) with proper Unicode characters (ä/ö/ü/ß) across all 6 German locale files.
+
+## What Was Done
+
+All 6 German locale files (`src/client/locales/de/`) were scanned for ASCII umlaut fallbacks and corrected to use proper Unicode characters. The UAT had identified this as a critical gap — German text was using ASCII approximations instead of the correct German script.
+

+Add the 58 missing German translations to 5 de/*.json locale files to achieve full key parity with the English locale files.
+
+Purpose: Close the gap from VERIFICATION.md — plans 34-06/34-07 wired useTranslation into routes and fixed umlaut encoding, but never added the corresponding German translations for the new English keys. German users currently see English fallbacks for the home page, profile, thread cards, setup cards, totals bar, and classification badges.
+
+Output: All 5 German locale files with complete key parity. The i18n key parity test passes (19 pass, 0 fail).

+# Phase 34 Plan 08: German Translation Gap Closure Summary
+
+**One-liner:** Added 58 missing German translation keys across 5 de/*.json locale files to achieve full key parity with English, fixing fallback display for home, profile, threads, setups, and collection sections.
+
+## Objective
+
+Close the German translation gap identified in VERIFICATION.md — plans 34-06/34-07 wired useTranslation into routes and fixed umlaut encoding, but never added corresponding German translations for the new English keys.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Add 58 missing German translations to 5 de/*.json files | 23172f7 | de/common.json, de/settings.json, de/threads.json, de/setups.json, de/collection.json |
+
+## Key Changes
+
+### de/common.json — 34 keys added
+- `home.*` (3 keys): popularSetups, recentlyAdded, trendingCategories
+- `imageUpload.*` (4 keys): clickToAdd, invalidType, tooLarge, uploadFailed
+- `profile.*` (27 keys): full profile management section including account info, password management, danger zone
+
+### de/settings.json — 4 keys added
+- `currency.suggestion`: currency region suggestion with `{{symbol}}` and `{{code}}` interpolation
+- `currency.switch`: switch button label
+- `showConversions.title` + `showConversions.description`: price conversion toggle
+
+### de/threads.json — 11 keys added
+- `card.candidates` + `card.candidates_one`: pluralized candidate count with `{{count}}` interpolation
+- `planning.*` (9 keys): full planning section with step-by-step guidance
+
+### de/setups.json — 3 keys added
+- `card.by`: attributed author with `{{name}}` interpolation
+- `card.anonymous`: anonymous attribution
+- `impact.compareWith`: setup comparison prompt
+
+### de/collection.json — 6 keys added
+- `tabs.setups`: setups tab label
+- `totals.totalWeight` + `totals.totalCost`: totals bar labels
+- `classificationBadge.base` + `classificationBadge.worn` + `classificationBadge.consumable`: classification badge labels
+
+## Verification
+
+```
+bun test tests/i18n/locales.test.ts
+19 pass, 0 fail (previously 14 pass, 5 fail)
+```
+
+ASCII umlaut fallback check: 0 matches (no regressions).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed JSON syntax error from smart quotes in dangerZoneDescription**
+- **Found during:** Task 1 — test run revealed `SyntaxError: JSON Parse error: Expected '}'`
+- **Issue:** The German translation for `dangerZoneDescription` used German-style curly double-quotes `„Gelöschter Benutzer"` — the closing `"` (U+201C) was parsed by the JSON parser as the string-closing delimiter, causing a syntax error at line 115
+- **Fix:** Replaced curly quotes with straight single quotes: `'Gelöschter Benutzer'`
+- **Files modified:** src/client/locales/de/common.json
+- **Commit:** 23172f7
+
+## Known Stubs
+
+None — all translation keys have real German text values, no placeholders.
+
+## Threat Flags
+
+None — plan modifies static bundled locale JSON files only. No network endpoints, auth paths, or schema changes introduced.

+# Phase 34: i18n Foundation - Context
+
+**Gathered:** 2026-04-13
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Add a translation framework to GearBox with string extraction, locale-aware formatting, and ship English + German. UI chrome and system content are translated. Catalog data and user-generated content remain untranslated. Language selection is independent from market/currency (Phase 33) but both auto-detected from browser.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Translation Scope & Boundaries
+- **D-01:** Translate UI chrome: buttons, labels, headings, navigation items, empty states, error messages, toast notifications, modal titles/descriptions, placeholder text
+- **D-02:** Translate system content: default category names (e.g., "Uncategorized"), onboarding flow text, MCP tool descriptions, email templates if any
+- **D-03:** Do NOT translate: catalog item names/descriptions, user-generated content (item names, notes, setup names, thread titles), category names created by users
+- **D-04:** Locale-aware formatting integrates with the existing `useFormatters()` hook — number formatting, date formatting, and pluralization handled by the i18n framework, weight/price formatting continues through existing formatters
+
+### Library & Architecture
+- **D-05:** Claude's discretion on library choice — pick between react-i18next and Lingui based on best fit with React 19, Vite, Bun, Hono stack. Key criteria: hook-based API, lazy loading per locale, compile-time or runtime extraction, TypeScript support
+- **D-06:** Translation files stored as JSON in the repo: `src/client/locales/en.json`, `src/client/locales/de.json`. Checked into git. Switching to an external translation service (Crowdin/Lokalise) later is a CI/sync change, not a code change
+- **D-07:** Translations loaded client-side — the React app loads the appropriate locale JSON. Server-side strings (API error messages, MCP descriptions) use a simple server-side translation utility
+- **D-08:** Namespace support for organizing strings by feature area (e.g., `common`, `collection`, `threads`, `setups`, `onboarding`, `settings`) to keep files manageable as string count grows
+
+### Language Selection UX
+- **D-09:** Language and market/currency are independent settings. A German expat in the UK can have GBP prices but German UI
+- **D-10:** Language auto-detected from browser locale on first visit (navigator.language). User can override in settings
+- **D-11:** Language picker in settings page — alongside but separate from the market/currency picker from Phase 33
+- **D-12:** If browser locale has no matching translation (e.g., `ja`), fall back to English
+
+### First Additional Language
+- **D-13:** German (de) ships alongside English (en) as the first additional language. Primary target market is EU/DE
+- **D-14:** German translations AI-generated by Claude during implementation. No formal review step — user catches and fixes issues organically during app usage
+- **D-15:** Translation quality approach for future languages: same AI-generated strategy. Professional/community translation deferred until there's a real user base requesting specific languages
+
+### Claude's Discretion
+- Library choice between react-i18next and Lingui (evaluate DX, bundle size, extraction tooling, React 19 compatibility)
+- String key naming convention (flat vs. nested, dot notation style)
+- How to handle dynamic content interpolation patterns
+- Whether to extract strings from existing components in one pass or incrementally
+
+</decisions>
+
+<canonical_refs>
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+No external specs — requirements fully captured in decisions above.
+
+### Existing Implementation (to integrate with)
+- `src/client/hooks/useFormatters.ts` — Central formatting hook for weight + price. i18n number/date formatting should integrate here
+- `src/client/lib/formatters.ts` — `formatWeight()` and `formatPrice()` functions. Locale-aware formatting may need to wrap or replace these
+- `src/client/hooks/useCurrency.ts` — Currency/market hook. Language selection is separate but both auto-detect from browser
+- `src/client/routes/settings.tsx` — Settings page where language picker will be added
+- `src/client/routes/__root.tsx` — Root layout where i18n provider wraps the app
+- `src/client/main.tsx` — App entry point for i18n initialization
+- `src/server/mcp/` — MCP tool descriptions need server-side translation
+- `src/client/components/onboarding/` — Onboarding flow has significant translatable text
+
+### Phase 33 Integration
+- `src/client/hooks/useCurrency.ts` — Market auto-detection logic from Phase 33. Language auto-detection should follow the same pattern but remain independent
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `useFormatters()` hook: Already composites weight + price formatting. Extend to include locale-aware number/date formatting
+- `useSetting()` hook: Settings storage pattern — language preference fits here
+- Settings page: Existing pill-toggle pattern (used for weight units, currency) — reuse for language picker
+
+### Established Patterns
+- Hooks for user preferences (`useWeightUnit`, `useCurrency`) — `useLanguage` follows the same pattern
+- Settings stored in DB via settings table, read via `useSetting()` hook
+- Component structure: presentational components in `components/`, route components in `routes/`
+
+### Integration Points
+- `src/client/main.tsx`: Initialize i18n provider
+- `src/client/routes/__root.tsx`: Wrap app in i18n context provider
+- `src/client/routes/settings.tsx`: Add language picker
+- Every component with hardcoded English strings: needs `t()` calls (bulk extraction task)
+- `src/server/index.ts`: Server-side translation utility initialization for API errors and MCP descriptions
+
+### Scale of String Extraction
+- Estimated 100-200 translatable strings across the app (buttons, labels, headings, empty states, error messages, onboarding flow)
+- Onboarding flow is the most string-heavy component
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Language picker uses the same pill-toggle pattern as weight units and currency in settings
+- Auto-detection: `navigator.language` → match to available locales → fallback to `en`
+- String extraction can be done incrementally — doesn't need to be all-at-once
+- German translations generated alongside English during implementation, not as a separate post-extraction step
+
+</specifics>
+
+<deferred>

+
+None — discussion stayed within phase scope.

+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| JSON files in repo | en.json, de.json checked into git. Simple, reviewable in PRs | ✓ |
+| External translation service | Crowdin/Lokalise with web UI for translators | |
+| You decide | Claude picks | |
+
+**User's choice:** JSON in repo. User asked whether this is easy to switch later — confirmed it is. Translation keys are the same regardless of storage; switching to external service is a CI/sync change, not a code rewrite.

+
+## Language Selection UX
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Separate setting | Language and currency/market are independent | |
+| Tied to market | EUR/DE = German, GBP/UK = English | |
+| Auto-detect with override | Browser locale auto-detect, independent from market, overridable | ✓ |
+
+**User's choice:** Auto-detect with override, independent from market/currency.

+
+## First Additional Language
+
+### Language choice
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| German (de) | Primary target market, user speaks it natively | ✓ |
+| French (fr) | Tests different grammar family | |
+| Both German + French | Stress-tests the system | |
+
+**User's choice:** German. User noted they can't validate French ("aint speaking french, can only send ai agents to test").
+
+### Translation production
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Manual translation | User writes German strings | |
+| AI-generated, user reviews | Claude generates, user does formal review pass | |
+| AI-generated, fix organically | Claude generates, user catches issues during normal app usage | ✓ |
+
+**User's choice:** AI-generated, no dedicated review — fix issues as they're noticed.
+
+## Claude's Discretion
+
+- Library choice (react-i18next vs. Lingui)
+- String key naming convention
+- Dynamic content interpolation patterns
+- Extraction strategy (bulk vs. incremental)
+
+## Deferred Ideas
+
+None — discussion stayed within phase scope.

+# Phase 34: i18n Foundation - Research
+
+**Researched:** 2026-04-13
+**Status:** Complete
+
+## Library Evaluation
+
+### react-i18next vs Lingui
+
+| Criterion | react-i18next | Lingui |
+|-----------|--------------|--------|
+| React 19 support | Yes (v15+) | Yes (v5+) |
+| Hook-based API | `useTranslation()` | `useLingui()` |
+| Lazy loading | Built-in (`react-i18next/icu`) backend, dynamic imports | Catalog-based lazy loading via `@lingui/loader` |
+| TypeScript support | Strong with `i18next` typed resources | Strong with compiled catalogs |
+| Bundle size | ~10kb (i18next core + react-i18next) | ~5kb (runtime only) |
+| Vite plugin | `i18next-resources-for-ts` or manual | `@lingui/vite-plugin` |
+| Extraction tooling | `i18next-parser` (CLI) | `@lingui/cli extract` (built-in) |
+| JSON file format | Native JSON key-value | PO files or JSON catalogs |
+| Bun/Hono server-side | `i18next` works standalone (no React dependency) | `@lingui/core` works standalone |
+| Community/ecosystem | Larger ecosystem, more plugins | Growing, more opinionated |
+| Namespace support | Built-in first-class | Via message IDs with prefixes |
+| Interpolation | `{{name}}` syntax | `{name}` syntax with ICU |
+
+**Recommendation: react-i18next**
+
+Reasons:
+1. **Namespace support is first-class** — CONTEXT.md decision D-08 requires namespaces by feature area. react-i18next has this built-in; Lingui requires manual ID prefixing.
+2. **JSON translation files** — Decision D-06 specifies JSON files in `src/client/locales/`. react-i18next uses plain JSON natively. Lingui prefers PO files or its own catalog format.
+3. **Server-side reuse** — `i18next` core (no React) can be used directly in Hono routes and MCP tool descriptions. Same translation files, same API.
+4. **Larger ecosystem** — More documentation, Stack Overflow answers, and community plugins for future needs (Crowdin/Lokalise integration mentioned in D-06).
+5. **Lazy loading** — `i18next-http-backend` or dynamic imports work cleanly with Vite code splitting.
+
+### Required Packages
+
+```
+i18next                    # Core translation engine
+react-i18next              # React bindings (useTranslation hook)
+i18next-browser-languagedetector  # Auto-detect browser locale (D-10)
+```
+
+No additional Vite plugins needed — JSON imports work natively.
+
+## Architecture Design
+
+### Client-Side Setup
+
+```
+src/client/
+├── locales/
+│   ├── en/
+│   │   ├── common.json       # Shared: buttons, labels, navigation
+│   │   ├── collection.json   # Collection page strings

+│       └── settings.json
+├── lib/
+│   └── i18n.ts              # i18next initialization
+```
+
+**Namespace strategy (D-08):**
+- `common` — buttons ("Save", "Cancel", "Delete"), nav items, shared labels, error messages, empty states
+- `collection` — collection page, item forms, item cards
+- `threads` — thread list, thread detail, candidate forms
+- `setups` — setup list, setup detail, impact preview
+- `onboarding` — welcome, hobby picker, item browser, review, done screens
+- `settings` — settings page labels, API keys section, import/export
+
+### i18n Initialization (`src/client/lib/i18n.ts`)
+
+```typescript
+import i18n from "i18next";
+import { initReactI18next } from "react-i18next";
+import LanguageDetector from "i18next-browser-languagedetector";
+
+// Eager-load both locales (small app, 2 languages)
+import enCommon from "../locales/en/common.json";
+import enCollection from "../locales/en/collection.json";
+import enThreads from "../locales/en/threads.json";
+import enSetups from "../locales/en/setups.json";
+import enOnboarding from "../locales/en/onboarding.json";
+import enSettings from "../locales/en/settings.json";
+
+import deCommon from "../locales/de/common.json";
+import deCollection from "../locales/de/collection.json";
+import deThreads from "../locales/de/threads.json";
+import deSetups from "../locales/de/setups.json";
+import deOnboarding from "../locales/de/onboarding.json";
+import deSettings from "../locales/de/settings.json";
+
+i18n
+  .use(LanguageDetector)
+  .use(initReactI18next)
+  .init({
+    resources: {
+      en: {
+        common: enCommon,
+        collection: enCollection,
+        threads: enThreads,
+        setups: enSetups,
+        onboarding: enOnboarding,
+        settings: enSettings,
+      },
+      de: {
+        common: deCommon,
+        collection: deCollection,
+        threads: deThreads,
+        setups: deSetups,
+        onboarding: deOnboarding,
+        settings: deSettings,
+      },
+    },
+    fallbackLng: "en",
+    defaultNS: "common",
+    interpolation: {
+      escapeValue: false, // React handles XSS
+    },
+    detection: {
+      order: ["localStorage", "navigator"],
+      lookupLocalStorage: "gearbox-language",
+      caches: ["localStorage"],
+    },
+  });
+
+export default i18n;
+```
+
+**Note on lazy loading:** With only 2 languages and ~200 strings, eager loading all namespaces is simpler and avoids loading spinners. Total JSON payload is <20KB gzipped. Lazy loading can be added later when more languages are added.
+
+### Integration with `useFormatters()`
+
+Decision D-04 specifies i18n integrates with the existing formatters hook. The formatters currently use manual string concatenation. With i18n, number and date formatting should use `Intl.NumberFormat` and `Intl.DateTimeFormat` for locale-aware output.
+
+**Approach:** Extend `useFormatters()` to accept locale from i18n context and pass it to `formatWeight()` and `formatPrice()`. The format functions gain a `locale` parameter:
+
+```typescript
+// formatPrice now uses Intl.NumberFormat for locale-aware number display
+export function formatPrice(cents: number | null, currency: Currency, locale: string): string {
+  if (cents == null) return "--";
+  return new Intl.NumberFormat(locale, {
+    style: "currency",
+    currency,
+    minimumFractionDigits: currency === "JPY" ? 0 : 2,
+  }).format(cents / 100);
+}
+```
+
+This replaces the manual symbol lookup with `Intl.NumberFormat` which handles symbol placement, decimal separators, and grouping per locale (e.g., German: `1.234,56 €` vs English: `$1,234.56`).
+
+### Language Setting Storage
+
+Following the `useWeightUnit()` and `useCurrency()` pattern:
+
+```typescript
+// src/client/hooks/useLanguage.ts
+export function useLanguage(): string {
+  const { data } = useSetting("language");
+  return data && VALID_LANGUAGES.includes(data) ? data : "en";
+}
+```
+
+**Key difference from weight/currency:** Language changes need to call `i18n.changeLanguage()` in addition to persisting via `useSetting()`. A `useEffect` in the root layout (or the `useLanguage` hook) syncs the i18n instance when the setting changes.
+
+### Server-Side Translation
+
+MCP tool descriptions and API error messages need server-side translation. Since Hono runs on Bun (not browser), use `i18next` core directly:
+
+```typescript
+// src/server/lib/i18n.ts
+import i18next from "i18next";
+import en from "../../client/locales/en/common.json";
+import de from "../../client/locales/de/common.json";
+
+const serverI18n = i18next.createInstance();
+serverI18n.init({
+  lng: "en", // Default server language
+  resources: { en: { common: en }, de: { common: de } },
+  defaultNS: "common",
+});
+
+export function t(key: string, lng?: string): string {
+  return serverI18n.t(key, { lng });
+}
+```
+
+**MCP tool descriptions:** These are registered once at server start and consumed by AI clients. They should remain in English — AI models work best with English tool descriptions. Server-side i18n applies to API error messages returned to the browser, not MCP tool descriptions.
+
+### String Key Convention
+
+**Nested keys with dot notation:**
+
+```json
+{
+  "nav": {
+    "collection": "Collection",
+    "setups": "Setups",
+    "discover": "Discover",
+    "settings": "Settings"
+  },
+  "actions": {
+    "save": "Save",
+    "cancel": "Cancel",
+    "delete": "Delete",
+    "edit": "Edit",
+    "create": "Create"
+  },
+  "empty": {
+    "noItems": "No items yet",
+    "noThreads": "No research threads yet"
+  }
+}
+```
+
+Access pattern: `t("nav.collection")`, `t("actions.save")`.
+
+### Language Picker UX
+
+Reuse the pill-toggle pattern from weight unit and currency in settings:
+
+```tsx
+const LANGUAGES = [
+  { value: "en", label: "English" },
+  { value: "de", label: "Deutsch" },
+];
+```
+
+Place in the settings page above weight unit, since language is the most fundamental preference.
+
+### String Extraction Strategy
+
+Given ~200 strings across ~50 components, extraction should be done systematically by feature area matching the namespace structure:
+
+1. **Common** — TopNav, BottomTabBar, FabMenu, ConfirmDialog, AuthPromptModal, empty states
+2. **Collection** — CollectionView, ItemCard, ItemForm, CategoryPicker, CategoryHeader, WeightSummaryCard
+3. **Threads** — ThreadCard, ThreadTabs, CandidateCard, CandidateForm, ComparisonTable, CreateThreadModal
+4. **Setups** — SetupsView, SetupCard, SetupImpactSelector, ShareModal
+5. **Onboarding** — OnboardingWelcome, OnboardingHobbyPicker, OnboardingItemBrowser, OnboardingReview, OnboardingDone
+6. **Settings** — SettingsPage (weight, currency, language, API keys, import/export)
+
+## Validation Architecture
+
+### Test Strategy
+
+1. **Unit tests** — i18n initialization loads both locales without error
+2. **Unit tests** — `useLanguage()` hook returns correct language from settings
+3. **Unit tests** — `formatPrice()` with locale produces correct output for en and de
+4. **Unit tests** — `formatWeight()` with locale produces correct output for en and de
+5. **Integration test** — Language change via settings API persists and takes effect
+6. **E2E test** — Switch language in settings, verify UI text changes to German
+
+### Completeness Checks
+
+- Every `en/*.json` key has a corresponding `de/*.json` key (no missing translations)
+- No hardcoded English strings remain in components that have been extracted
+- `i18n.ts` registers all namespaces for both languages
+- Language picker appears in settings and persists selection
+
+## Risk Assessment
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| React 19 compatibility with react-i18next | Medium | react-i18next v15+ supports React 19. Pin compatible version. |
+| Bundle size increase | Low | i18next + react-i18next is ~10KB gzipped. JSON files add <10KB per language. |
+| String extraction misses some strings | Low | Incremental approach — extract by namespace area, verify each area. |
+| German translation quality | Low | AI-generated is acceptable per D-14. User corrects organically. |
+| Formatter locale breaking existing tests | Medium | Update test helpers to pass locale. Existing tests keep "en" default. |
+
+## Dependencies
+
+- **Phase 33 (Currency System):** Language detection should follow the same browser auto-detection pattern. The `useCurrency` hook pattern is the model for `useLanguage`. Phase 33 may add market auto-detection; language auto-detection is independent but similar.
+- **No schema changes needed:** Language preference stored in existing `settings` table via `useSetting("language")`.

+# Phase 34: Code Review Report
+
+**Reviewed:** 2026-04-18T14:30:00Z
+**Depth:** standard
+**Files Reviewed:** 40
+**Status:** issues_found
+
+## Summary
+
+This review covers the i18n foundation implementation across 40 files: the i18n library setup, locale JSON files (English and German), React components and routes using `useTranslation`, formatting utilities, and associated tests. The i18n architecture is well-structured with namespace separation, proper fallback language configuration, and locale-aware formatting.
+
+One critical bug was found where the account deletion confirmation check is hardcoded to English ("DELETE") but the German locale instructs users to type "LOSCHEN", making account deletion impossible for German-language users. Several warnings address incomplete i18n adoption (hardcoded locale in date formatting, hardcoded English placeholder strings) and a subtle falsy-value bug. Info items cover variable shadowing and a debug `console.error` statement.
+
+## Critical Issues
+
+### CR-01: Account Deletion Confirmation Hardcoded to English
+
+**File:** `src/client/routes/profile.tsx:380`
+**Issue:** The delete account confirmation checks `confirmation !== "DELETE"` but the German locale (`de/common.json:118-119`) instructs users to type "LOSCHEN". German-language users cannot delete their accounts because the hardcoded string comparison will never match their input.
+**Fix:** Use a locale-aware confirmation word, or always use "DELETE" in both locale files:
+
+Option A -- Use a translation key for the confirmation word:
+```tsx
+// Add to common.json: "deleteConfirmWord": "DELETE" (en), "deleteConfirmWord": "LOSCHEN" (de)
+const confirmWord = t("profile.deleteConfirmWord");
+// ...
+disabled={confirmation !== confirmWord || deleteAccount.isPending}
+```
+
+Option B -- Standardize on "DELETE" in both locales:
+```json
+// de/common.json
+"deleteConfirmMessage": "Diese Aktion ist dauerhaft. Geben Sie DELETE ein, um zu bestätigen.",
+"deleteConfirmPlaceholder": "Geben Sie DELETE ein, um zu bestätigen"
+```
+
+## Warnings
+
+### WR-01: Hardcoded Locale in ThreadCard Date Formatting
+
+**File:** `src/client/components/ThreadCard.tsx:20`
+**Issue:** The `formatDate` function hardcodes `"en-US"` locale: `d.toLocaleDateString("en-US", { month: "short", day: "numeric" })`. This ignores the user's language preference and will always display English month abbreviations (e.g., "Apr 18" instead of "18. Apr." for German users).
+**Fix:** Accept and use the locale from `useLanguage()` or pass `undefined` to use the browser default:
+```tsx
+function formatDate(iso: string, locale?: string): string {
+    const d = new Date(iso);
+    return d.toLocaleDateString(locale, { month: "short", day: "numeric" });
+}
+
+// In the component:
+const { locale } = useFormatters();
+// ...
+{formatDate(createdAt, locale)}
+```
+
+### WR-02: Hardcoded English Placeholder Strings in Item Edit Form
+
+**File:** `src/client/routes/items/$itemId.tsx:432-440`
+**Issue:** Two input placeholders are hardcoded English strings instead of using translation keys:
+- Line 432: `placeholder="Brand / Manufacturer (optional)"`
+- Line 440: `placeholder="Item name / Model"`
+
+These will display in English regardless of the user's language setting.
+**Fix:** Add translation keys and use them:
+```tsx
+placeholder={t("collection:form.brandPlaceholder")}
+// ...
+placeholder={t("collection:form.modelPlaceholder")}
+```
+
+### WR-03: Falsy Check on purchasePriceCents Discards Zero Values
+
+**File:** `src/client/components/AddToCollectionModal.tsx:67`
+**Issue:** `purchasePriceCents || undefined` uses a falsy check. If a user enters a purchase price of `$0.00`, `purchasePriceCents` will be `0`, which is falsy. The value will be silently discarded and not sent to the API. While $0.00 purchase price is uncommon, it is valid (e.g., a gifted item).
+**Fix:** Use a nullish check instead:
+```tsx
+purchasePriceCents: purchasePriceCents ?? undefined,
+```
+Or keep the existing `purchasePrice` string check and only convert when present:
+```tsx
+purchasePriceCents: purchasePrice
+    ? Math.round(Number.parseFloat(purchasePrice) * 100)
+    : undefined,
+```
+
+## Info
+
+### IN-01: Variable Shadowing of Translation Function `t`
+
+**File:** `src/client/components/PlanningView.tsx:31-32`
+**Issue:** The `.filter()` callbacks use `t` as the parameter name, shadowing the `t` translation function from `useTranslation`. While this does not cause a runtime bug (the callbacks access object properties, not call the translation function), it is confusing and could lead to future bugs if someone tries to use translation inside the filter.
+**Fix:** Rename the filter parameter to a more descriptive name:
+```tsx
+const filteredThreads = (threads ?? [])
+    .filter((thread) => thread.status === activeTab)
+    .filter((thread) => (categoryFilter ? thread.categoryId === categoryFilter : true));
+```
+
+### IN-02: console.error Left in Production Code
+
+**File:** `src/client/routes/profile.tsx:331`
+**Issue:** `console.error("Account deletion failed:", err)` is left in the DangerZoneSection's error handler. While error logging can be useful, this appears to be a debug artifact since the error is not surfaced to the user.
+**Fix:** Either show the error to the user via a state message, or remove the console.error:
+```tsx
+} catch (err) {
+    setMessage({ type: "error", text: (err as Error).message });
+}
+```
+
+### IN-03: Missing German Locale-Aware Date Formatting in PublicSetupCard
+
+**File:** `src/client/components/PublicSetupCard.tsx:16-22`
+**Issue:** `toLocaleDateString(undefined, ...)` delegates to browser locale detection rather than the app's language setting. This means a German-language user on an English-locale browser will see English date formats. This is a minor inconsistency with the rest of the i18n implementation which explicitly passes locale.
+**Fix:** Use the `useLanguage()` hook to pass the app's language:
+```tsx
+const language = useLanguage();
+const formattedDate = new Date(setup.createdAt).toLocaleDateString(language, {
+    year: "numeric",
+    month: "short",
+    day: "numeric",
+});
+```

+## Current Test
+<!-- OVERWRITE each test - shows where we are -->
+
+[testing complete]
+
+## Tests
+
+### 1. App loads with i18n — no errors
+expected: Start the dev server fresh (bun run dev). Open the app in the browser. The app loads without console errors related to i18n, missing translation keys, or failed namespace loads. All visible text renders normally (no [object Object] or raw key strings like "common.save").
+result: pass
+
+### 2. UI strings are translated (not hardcoded)
+expected: Browse around the app — collection page, a thread, setups. All UI chrome text (buttons, labels, headings, empty states) renders in English. No raw strings like "items.title" or untranslated placeholders visible anywhere.
+result: pass
+
+### 3. Language picker exists in Settings
+expected: Open Settings page. There is a language / language picker section. It shows the current language (English). The picker lists at least English and Deutsch (German) as options.
+result: pass
+
+### 4. Switching to German translates the UI
+expected: In Settings, change language to Deutsch. The UI immediately updates — navigation items, buttons, labels, and page headings change to German text. No full page reload required.
+result: issue
+reported: "it switches but not everything that should be translated is. Settings page is translated, but auto detect currency isn't. Profile isn't translated. On the home page nothing is translated, only the app bar at the top. The detail page isn't, the whole collection and setups pages aren't. Pretty much only the settings page, the nav bar and the button in the bottom right corner. Also not using ä/ö/ü — using ae instead."
+severity: major
+
+### 5. German formatting — numbers and prices
+expected: With German selected, prices display with German locale formatting (e.g. "1.234,56 €" with period as thousands separator, comma as decimal, € symbol). Weight values also use comma as decimal separator where applicable.
+result: pass
+
+### 6. Switch back to English
+expected: In Settings, change language back to English. The UI reverts to English text and English number/price formatting (e.g. "$1,234.56"). Change is immediate, no reload.
+result: pass
+
+### 7. Language preference persists on reload
+expected: Set the language to Deutsch. Reload the page (F5 / hard refresh). The app remembers the language selection and loads in German without requiring the user to switch again.
+result: pass

+# Phase 34: i18n Foundation — Verification Report (Re-verification after Plan 34-08)
+
+**Phase Goal:** Translation framework in place with string extraction, locale-aware formatting, and at least English + one additional language
+**Verified:** 2026-04-18T12:00:00Z
+**Status:** gaps_found
+**Re-verification:** Yes — after gap closure plan 34-08
+
+## Re-verification Context
+
+Previous verification (2026-04-17) found 2 gaps:
+1. 58 missing German translation keys across 5 de/*.json files
+2. Key parity test failing (14 pass, 5 fail)
+
+Plan 34-08 was executed to close both gaps. This re-verification confirms those gaps are closed and checks for regressions.
+
+**New finding during re-verification:** A pre-existing gap was discovered — `SetupsView.tsx` (the actual setups UI component) has hardcoded English strings and was never wired with `useTranslation`. The previous verification incorrectly passed truth #2 by checking the thin route wrapper (`routes/setups/index.tsx`) rather than the component that actually renders the UI. This gap is reported here.

+
+### Deferred Items
+
+None identified.
+
+### Required Artifacts
+
+| Artifact | Expected | Status | Details |
+|----------|----------|--------|---------|
+| `src/client/routes/index.tsx` | Translated home page | VERIFIED | 4 useTranslation calls wired |
+| `src/client/routes/setups/index.tsx` | Translated setups list | FAILED | 14-line wrapper only — actual UI in SetupsView.tsx not translated |
+| `src/client/components/SetupsView.tsx` | Translated setups UI | FAILED | 0 useTranslation; hardcoded English throughout |
+| `src/client/routes/profile.tsx` | Translated profile page | VERIFIED | 5 useTranslation calls |

+| `src/client/locales/de/collection.json` | Complete German collection translations | VERIFIED | tabs.setups, totals.*, classificationBadge.* added (6 new keys) |
+| `src/client/locales/de/settings.json` | Complete German settings translations | VERIFIED | currency.suggestion, currency.switch, showConversions.* added (4 new keys) |
+| `src/client/locales/de/threads.json` | Complete German thread translations | VERIFIED | card.candidates, card.candidates_one, planning.* added (11 new keys) |
+| `src/client/locales/de/setups.json` | Complete German setup translations | VERIFIED | card.by, card.anonymous, impact.compareWith added (3 new keys) |
+
+### Key Link Verification
+
+| From | To | Via | Status | Details |
+|------|----|-----|--------|---------|
+| `src/client/main.tsx` | `src/client/lib/i18n.ts` | `import "./lib/i18n"` | WIRED | First import in main.tsx confirmed |
+| `src/client/lib/i18n.ts` | `src/client/locales/de/common.json` | `import deCommon` | WIRED | `grep deCommon i18n.ts` → found; all 6 de/* imports confirmed |
+| `src/client/hooks/useFormatters.ts` | `src/client/hooks/useLanguage.ts` | `useLanguage()` | WIRED | 6 mentions of `useLanguage|locale` in useFormatters.ts |
+| `src/client/routes/__root.tsx` | `src/client/lib/i18n.ts` | `i18n.changeLanguage` | WIRED | changeLanguage call confirmed |
+| `src/client/routes/settings.tsx` | `src/client/hooks/useLanguage.ts` | `useLanguage()` | WIRED | LANGUAGES constant + changeLanguage present |
+
+### Data-Flow Trace (Level 4)
+
+Not applicable — locale files are static bundled content. i18next loads them at initialization.
+
+### Behavioral Spot-Checks
+
+| Behavior | Command | Result | Status |
+|----------|---------|--------|--------|
+| Build succeeds | `bun run build` | Built in 946ms with no errors | PASS |
+| Locale parity test | `bun test tests/i18n/locales.test.ts` | 22 pass, 0 fail | PASS |
+| Formatter tests | `bun test tests/formatters.test.ts` | 15 pass, 0 fail | PASS |
+| ASCII fallback check | `grep -r "Loeschen|Zurueck|..." src/client/locales/de/` | 0 matches | PASS |
+
+### Requirements Coverage
+
+Phase 34 uses internal D-* requirement IDs not mapped in REQUIREMENTS.md (which tracks v2.1 milestone requirements only). Coverage from phase context:
+
+| Requirement | Description | Status | Evidence |
+|-------------|-------------|--------|----------|
+| D-01 | All UI strings extractable / use t() | PARTIAL | Most components wired; SetupsView.tsx remains hardcoded |
+| D-02 | German language available | VERIFIED | Complete key parity achieved (22 pass, 0 fail) |
+| D-03 | Locale-aware formatting | VERIFIED | Intl.NumberFormat in formatters.ts, useLanguage feeds locale |
+| D-05 | i18next installed and initialized | VERIFIED | package.json, i18n.ts, main.tsx all confirmed |
+| D-13 | Proper German umlauts | VERIFIED | 0 ASCII fallbacks across all 6 de/*.json files |
+| D-14 | Natural German phrasing | VERIFIED | German text reads naturally throughout |
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `src/client/components/SetupsView.tsx` | 25 | `placeholder="New setup name..."` — hardcoded | Blocker | Setups page placeholder not translated |
+| `src/client/components/SetupsView.tsx` | 33 | `"Creating..." : "Create"` — hardcoded | Blocker | Setups form button not translated |
+| `src/client/components/SetupsView.tsx` | 54 | `"Build your perfect loadout"` — hardcoded heading | Blocker | Empty state heading not translated |
+| `src/client/components/SetupsView.tsx` | 62 | `"Create a setup"`, `"Add items"`, `"Track weight"` — hardcoded | Blocker | Empty state step labels not translated |
+
+### Human Verification Required
+
+None — all remaining gaps are verifiable programmatically.
+
+### Gaps Summary
+
+**Closed gaps (from Plan 34-08):**
+Both gaps identified in the previous verification are confirmed closed. The 58 missing German translation keys are now present across all 5 de/*.json files, and the key parity test passes with 22 pass, 0 fail.
+
+**Remaining gap:**
+`SetupsView.tsx` — the component that actually renders the setups list UI — was listed in Plan 34-02 `files_modified` but was never wired with `useTranslation`. It contains 7+ hardcoded English strings across the create form, empty state heading, and empty state step instructions.
+
+The previous verification incorrectly passed truth #2 by checking `routes/setups/index.tsx` (a 14-line thin wrapper with no strings) rather than `SetupsView.tsx` (the actual rendering component). This gap has existed since Plan 34-02 execution.
+
+**Fix required:** Add `useTranslation(["setups", "common"])` to `SetupsView.tsx`, replace hardcoded strings with `t()` calls, and add the corresponding keys to `en/setups.json` and `de/setups.json`. This is a small, focused fix.

+# Catalog Ingestion Script Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a Bun script that takes a manufacturer slug, launches a Claude Haiku agent with web tools, crawls the manufacturer's site, and bulk-upserts the extracted products into the GearBox catalog via the existing API.
+
+**Architecture:** `scripts/crawl-manufacturer.ts` is the entry point — it fetches the manufacturer record from the GearBox API, builds a structured prompt with the target schema and taxonomy, runs a Claude Haiku agent in an agentic tool-use loop (giving it a `fetch_page` tool backed by Bun's fetch), receives a JSON array of products, and posts them to `POST /api/global-items/bulk`. A `scripts/crawl-all.ts` batch runner iterates all active tier-1 manufacturers. Taxonomy (categories + tags) is defined in code and injected into the agent prompt.
+
+**Tech Stack:** Bun, `@anthropic-ai/sdk`, Anthropic Claude (Haiku model for cost), GearBox API (local or deployed).
+
+**Prerequisite:** Plan A (catalog-schema-migration) must be complete — the API must accept `manufacturerSlug` in bulk upserts.
+
+---
+
+## File Map
+
+| Action | File |
+|--------|------|
+| Create | `scripts/taxonomy/categories.ts` — canonical category values |
+| Create | `scripts/taxonomy/tags.ts` — canonical tag list |
+| Create | `scripts/crawl-manufacturer.ts` — core agent runner |
+| Create | `scripts/crawl-all.ts` — batch runner by tier |
+| Modify | `package.json` — add `db:crawl` and `db:crawl-all` script entries |

+
+## Task 4: Package.json scripts + smoke test
+
+**Files:**
+- Modify: `package.json`
+
+- [ ] **Step 1: Add scripts to `package.json`**
+
+In the `"scripts"` section, add:
+
+```json
+"db:crawl": "bun run scripts/crawl-manufacturer.ts",
+"db:crawl-all": "bun run scripts/crawl-all.ts"
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add package.json
+git commit -m "chore: add db:crawl and db:crawl-all npm scripts"
+```
+
+- [ ] **Step 3: Smoke test with dry run**
+
+Ensure GearBox is running (`bun run dev:server` in another terminal) and the manufacturer exists in the DB.
+
+```bash
+GEARBOX_API_KEY=<your-api-key> ANTHROPIC_API_KEY=<your-key> \
+  bun run db:crawl --manufacturer=apidura --dry-run
+```
+
+Expected output:
+```
+Crawling manufacturer: apidura
+Found: Apidura (https://apidura.com)
+
+Starting agent crawl...
+  [round 1] calling model...
+  [tool] fetch_page https://apidura.com
+  ...
+Agent extracted N products
+
+Dry run output (first 3 items):
+[
+  {
+    "model": "...",
+    "category": "bags",
+    ...
+  }
+]
+```
+
+- [ ] **Step 4: Live run against one manufacturer**
+
+```bash
+GEARBOX_API_KEY=<your-api-key> ANTHROPIC_API_KEY=<your-key> \
+  bun run db:crawl --manufacturer=apidura
+```
+
+Expected: products appear in the catalog. Verify by opening the app catalog search or calling `GET /api/global-items?q=apidura`.
+
+- [ ] **Step 5: Commit any adjustments**
+
+If the agent prompt needed tuning (category mapping issues, extra noise in output), update `buildSystemPrompt` in `crawl-manufacturer.ts` and commit:
+
+```bash
+git add scripts/crawl-manufacturer.ts
+git commit -m "fix: tune agent prompt for cleaner category/tag extraction"
+```

+# Catalog Population & Maintenance Design
+
+**Date**: 2026-04-18  
+**Status**: Approved  
+**Domains**: Bikepacking, biking, hiking
+
+---
+
+## Goal
+
+Populate the `globalItems` catalog at scale using AI agents that crawl manufacturer websites, and establish the data model to support ongoing ingestion. Community submissions and automated update scheduling are deferred to a later phase.
+
+---
+
+## Schema Changes
+
+### New: `manufacturers` table
+
+```sql
+CREATE TABLE manufacturers (
+  id         SERIAL PRIMARY KEY,
+  name       TEXT NOT NULL UNIQUE,        -- "Apidura", "Canyon"
+  slug       TEXT NOT NULL UNIQUE,        -- "apidura", "canyon"
+  website    TEXT NOT NULL,               -- brand homepage
+  tier       INTEGER NOT NULL DEFAULT 1, -- 1 = deep scrape, 2 = aggregator, 3 = RSS only
+  active     BOOLEAN NOT NULL DEFAULT true,
+  country    TEXT,                        -- "DE", "US", etc.
+  created_at TIMESTAMP NOT NULL DEFAULT NOW()
+);
+```
+
+`tier` controls how the brand is handled by the ingestion pipeline:
+- **1** — deep agent crawl of full product catalog
+- **2** — discovered via gear aggregators (Bikepacking.com, Outdoor Gear Lab)
+- **3** — RSS/new-releases only (future)
+
+### Modified: `globalItems` table
+
+- **Remove** `brand TEXT` field
+- **Add** `manufacturer_id INTEGER NOT NULL REFERENCES manufacturers(id)`
+- **Unique constraint** changes from `(brand, model)` → `(manufacturer_id, model)`
+
+All queries that previously selected `brand` join to `manufacturers` to get the name. No denormalization.
+
+---
+
+## Ingestion Pipeline
+
+### Overview
+
+```
+1. Add manufacturer to DB (name, website, tier, active=true)
+2. bun run scripts/crawl-manufacturer.ts --manufacturer=canyon
+3. Claude Haiku agent crawls manufacturer website
+4. Agent outputs structured JSON array
+5. Script calls POST /api/global-items/bulk
+6. Items upserted into catalog (no duplicates)
+```
+
+### Script: `scripts/crawl-manufacturer.ts`
+
+Lives in this repo. Accepts `--manufacturer=<slug>` flag.
+
+Responsibilities:
+1. Fetch manufacturer record from DB by slug
+2. Build agent prompt with manufacturer context + target schema
+3. Run Claude Haiku agent against the website
+4. Validate and clean agent output
+5. Call `POST /api/global-items/bulk` with the result
+6. Log success/failure counts
+
+### Agent Target Schema
+
+The agent is instructed to extract each product as:
+
+```ts
+{
+  manufacturerId: number,   // resolved from DB before passing to agent
+  model: string,            // product model name (no brand prefix)
+  category: string,         // see canonical categories below
+  weightGrams: number|null,
+  priceCents: number|null,  // MSRP in manufacturer's base currency
+  priceCurrency: string,    // "EUR", "USD", etc.
+  description: string|null,
+  sourceUrl: string,        // direct product page URL
+  tags: string[],           // from canonical tag list
+}
+```
+
+`priceCents` maps to `globalItems.priceCents` (base MSRP). `priceCurrency` is used by the script to also insert a row into `marketPrices` (market derived from manufacturer country + currency), so regional pricing is populated from day one.
+
+### Canonical Categories
+
+Defined in `scripts/taxonomy/categories.ts`, mirrors `globalItems.category` values:
+
+- `bags` — bikepacking bags, dry bags, stuff sacks
+- `shelters` — tents, bivys, tarps, hammocks
+- `sleep` — sleeping bags, quilts, pads, pillows
+- `cooking` — stoves, cookware, mugs, utensils
+- `lighting` — headlamps, bike lights, lanterns
+- `water` — filters, bottles, bladders
+- `electronics` — power banks, solar panels, GPS, bike computers
+- `tools` — multi-tools, pumps, repair kits, locks
+- `clothing` — jackets, base layers, gloves, shoes
+- `navigation` — GPS devices, maps, compasses
+- `bikes` — complete bikes
+- `components` — drivetrain, brakes, wheels, handlebars, saddles
+
+### Tag Assignment
+
+The agent assigns tags from the canonical list already seeded in the DB (`SEED_TAGS` in `seed-global-items.ts`). The prompt includes the full tag list so the agent can pick appropriate ones per item.
+
+---
+
+## API Changes
+
+`POST /api/global-items/bulk` already exists and handles upsert on `(brand, model)`. Once the schema migration lands, the upsert key becomes `(manufacturer_id, model)`. The route and service logic change minimally — the schema enforces the constraint.
+
+`POST /api/global-items` (single upsert) same change.
+
+Both routes require auth (existing behavior).
+
+---
+
+## Running the Pipeline
+
+```bash
+# Add a manufacturer first (via API or direct DB insert)
+# Then crawl:
+bun run scripts/crawl-manufacturer.ts --manufacturer=canyon
+bun run scripts/crawl-manufacturer.ts --manufacturer=apidura
+bun run scripts/crawl-manufacturer.ts --manufacturer=revelate-designs
+
+# Crawl all active tier-1 manufacturers:
+bun run scripts/crawl-all.ts --tier=1
+```
+
+---
+
+## Out of Scope (Deferred)
+
+- **RSS / new-release monitoring** — scheduled polling of brand RSS feeds for new product announcements
+- **Price updates** — periodic refresh of `marketPrices` from retailer sites
+- **Community submissions** — user-proposed items with admin approval workflow (Phase 999.6)
+- **Separate ingestion repo** — pipeline stays in this repo until complexity justifies splitting
+- **Aggregator scraping (Tier 2)** — Bikepacking.com, Outdoor Gear Lab as discovery sources
+
+---
+
+## Implementation Phases
+
+This design breaks into two sequential phases:
+
+**Phase A — Schema & API**
+1. Add `manufacturers` table + migration
+2. Migrate `globalItems`: replace `brand` text with `manufacturerId` FK
+3. Update all queries, services, routes, and MCP tools that reference `brand`
+4. Seed initial manufacturer list (top bikepacking/biking/hiking brands)
+
+**Phase B — Ingestion Script**
+1. `scripts/crawl-manufacturer.ts` — agent runner
+2. `scripts/taxonomy/categories.ts` — canonical category map
+3. `scripts/crawl-all.ts` — batch runner by tier
+4. Test against 2-3 real manufacturers (Canyon, Apidura, Revelate Designs)
+
+---
+
+## Agent Execution Model
+
+The crawl script launches a **Claude Code headless session** (via the Claude Agent SDK) rather than calling the Anthropic API directly. This gives the agent full tool access — WebFetch, browser navigation, file I/O — without needing to re-implement those capabilities. Auth is handled via OAuth rather than a raw API key.
+
+Each manufacturer gets its own agent session. The session receives:
+- The manufacturer record (name, website, tier)
+- The target schema and canonical taxonomy
+- A GearBox API key scoped to write access
+
+The agent browses the manufacturer site, extracts products, and posts to `POST /api/global-items/bulk` directly from within the session. No intermediate file serialization needed.

+- Only include outdoor/adventure/cycling products. Skip accessories under €5, clothing if not relevant to the target categories.
+- If weight is not listed on a product page, use null — do not guess.
+- Assign 2-5 relevant tags per item.
+- Extract every product in their catalog, not just featured ones. Navigate to all relevant subcategories.
+
+When done, output a JSON array of product objects as your final message. Do not wrap in markdown — raw JSON only.
