+# Kitchen Intelligence Suite — Implementation Plan
+
+_Comprises **Recipe Collector**, **Digital Pantry**, and **Meal Planner** working together to auto-generate shopping lists and optimise household grocery workflows._
+
+---
+
+## 1. Product Goals
+1. Centralise recipe collection (web clipper, manual entry, photo OCR).
+2. Provide frictionless meal-planning on a calendar UI.
+3. Maintain a live Digital Pantry (inventory) sourced from shopping lists & expenses.
+4. Produce consolidated shopping lists by comparing planned meals vs pantry stock.
+
+## 2. High-Level Architecture
+```
+Browser Clipper / Mobile App
+        ↓ (REST / gRPC)
+Backend  (FastAPI)  ─► Recipe ↔ Ingredient ↔ Pantry Stock
+                         │
+                         └─► MealPlanCalendar ▷ Auto ShoppingList ▷ Existing List system
+```
+- **Backend** utilises existing FastAPI + Postgres; re-use OCR, list & expense models where possible.
+- **Services**: recipe parser, nutrition API integration, suggestion engine.
+
+## 3. Database Design
+| Model | Fields | Notes |
+|-------|--------|-------|
+| `Recipe` | `id`, `group_id`, `title`, `source_url`, `image_url`, `instructions_md`, `created_by_id`, timestamps | Markdown instructions for rich text |
+| `RecipeIngredient` | `id`, `recipe_id`, `name`, `quantity`, `unit`, `raw_text` | Denormalised for simplicity |
+| `RecipeTag` | `recipe_id`, `tag` | Simple tag list |
+| `PantryItem` | `id`, `group_id`, `name`, `quantity`, `unit`, `expires_at`, `updated_at` | Synced from expenses & manual edits |
+| `MealPlan` | `id`, `group_id`, `date`, `recipe_id`, `servings`, `position` | Multiple recipes per day possible |
+
+*Indices on (`group_id`, `date`) for fast calendar queries.*
+
+## 4. Backend API Surface (v1)
+```
+# Recipes
+POST   /recipes/clip           → create from URL (async parse)
+POST   /recipes/ocr            → upload photo; returns draft recipe
+POST   /recipes                → manual create
+GET    /recipes?tag=&query=    → search & filter
+GET    /recipes/{id}           → detail
+PUT    /recipes/{id}           → update
+DELETE /recipes/{id}
+
+# Meal Planner
+GET    /mealplan?start=&end=   → range fetch
+POST   /mealplan               → add recipe to date
+DELETE /mealplan/{id}
+
+# Pantry
+GET    /pantry                 → list stock
+PUT    /pantry/{id}            → adjust qty / mark consumed
+
+# Magic Button
+POST   /shopping-list/generate?start=2025-01-01&end=2025-01-07
+      → returns consolidated list; also persists to existing List entity
+```
+
+## 5. Key Services
+1. **Recipe Parser Service**  
+   - Uses `recipe-scrapers` library + custom fallbacks.  
+   - Normalises units (ml, g, cups) via `quantulum3`.
+2. **Photo OCR Pipeline**  
+   - Re-use existing Tesseract / Google Vision integration.  
+   - Heuristic line-by-line ingredient detection.
+3. **Shopping List Generator**  
+   - Inputs: planned recipes, servings, pantry items.  
+   - Algorithm:
+     ```python
+     needed = Counter()
+     for plan in plans:
+         for ing in plan.ingredients:
+             qty = convert_to_base_unit(ing.quantity, ing.unit)
+             needed[ing.name] += qty
+     for stock in pantry:
+         needed[stock.name] -= stock.quantity_base
+     final = {name: qty for name, qty in needed.items() if qty > 0}
+     ```
+   - Outputs `List` + `Item` rows; marks them `is_auto_generated=True`.
+4. **Pantry Synchroniser**  
+   - After expense settlement or list completion, increment `PantryItem` quantities.
+
+## 6. Front-End Work (Vue 3)
+### 6.1 Recipe Collector UI
+- `RecipeGallery.vue` (masonry grid w/ tag filters)
+- `RecipeDetailSheet.vue` (view & edit)
+- `RecipeImportDialog.vue` (URL / photo upload)
+- `TagSelector.vue`
+
+### 6.2 Meal Planner UI
+- `MealPlannerCalendar.vue` (drag-n-drop, week & month views)
+- `MealPlannerSidebar.vue` (recipe search & quick add)
+- `MealPlanDayCard.vue`
+
+### 6.3 Pantry UI
+- `PantryList.vue` (sortable table; colour-coded expirations)
+
+### 6.4 Stores
+- `useRecipeStore`, `useMealPlanStore`, `usePantryStore` with optimistic updates.
+
+## 7. Browser Clipper Extension
+- MV3 Chrome/Firefox extension; minimal popup with "Save to mitlist".  
+- Sends URL + selected text/image to `/recipes/clip`.  
+- Auth via existing JWT; allow device pairing QR for quick login.
+
+## 8. Integration with Existing Lists Module
+- Generated shopping list saved as hidden list (`type=generated`, `source="meal-plan"`).
+- Users can tweak items before marking list complete.
+
+## 9. Background Jobs & Workers
+- Async parsing & OCR handled by Celery.
+- Nightly job to decrement pantry stock based on MealPlan (consume ingredients on the day).
+
+## 10. Permissions & Roles
+- Same as lists/expenses: group-scoped; only members can modify; owners can delete.
+
+## 11. Migration Steps
+1. Alembic migrations for new tables.  
+2. Back-fill pantry from last 90 days expenses.  
+3. Deploy backend behind feature flag.  
+4. Release Recipe Collector UI (alpha) → gather feedback.  
+5. Ship Meal Planner + Magic Button.  
+6. Turn on automatic pantry sync.
+
+## 12. Analytics & Success Metrics
+- Weekly Active Meal Planners.  
+- Avg. recipes saved per user.  
+- % shopping lists auto-generated.  
+- Reduction in grocery budget (optional survey).
+
+## 13. Timeline Estimate
+| Milestone | Duration |
+|-----------|----------|
+| DB & API scaffold (recipes, pantry) | 3 w |
+| Clipper extension MVP | 2 w |
+| OCR import & parser refinements | 2 w |
+| Meal Planner calendar + Shopping List generator | 3 w |
+| Pantry sync & consumption logic | 2 w |
+| UX polish, QA, beta rollout | 2 w |
+
+_Total ≈ 12 weeks with 2 engineers (1 BE, 1 FE) + part-time designer._
+
+## 14. Integration with Existing Codebase
+
+### 14.1 Backend Reuse & Patterns
+- **CRUD Base**: Implement `crud/recipe.py`, `crud/pantry.py`, `crud/meal_plan.py` inheriting from existing `CRUDBase` (see `crud/list.py`).
+- **Dependency Injection**: Continue using `Depends(get_current_user)`, `Depends(get_db)` per existing routers.
+- **Path Organization**: Place new endpoints in `app/api/v1/endpoints/recipes.py`, `mealplanner.py`, `pantry.py`; include them in `api_router_v1` with appropriate prefixes.
+- **Transactions Strategy**: Follow rule `fastapi-db-strategy` ([[fetch_rules]]) for wrap-in-transaction per request or unit-of-work pattern.
+- **Existing List & Item models**: Shopping list generator will directly create `List` and `Item` rows to avoid duplicating list logic. Flag items with `is_generated` boolean (schema change in migrations).
+- **Expense Hooks**: Use SQLAlchemy event listener on `Expense` insert to update `PantryItem` quantities.
+- **Job Scheduling**: Add Celery beat tasks next to `jobs/recurring_expenses.py` (e.g., `jobs/pantry_sync.py`).
+
+### 14.2 Front-End Alignment
+- **Services**: Add `recipeService.ts`, `mealPlanService.ts`, `pantryService.ts` in `src/services`. Pattern after `expenseService.ts` with generic `api.ts` wrapper.
+- **Pinia Stores**: `recipeStore.ts`, `mealPlanStore.ts`, `pantryStore.ts` mirroring structure of `choreStore.ts` (actions for fetch, create, delete, optimistic updates helper).
+- **Composable Utilities**: `useMealPlanner.ts` providing drag-and-drop helpers, reusing `useOptimisticUpdates` and `useOfflineSync`.
+- **Routing**:
+  ```ts
+  { path: '/recipes', name: 'Recipes', component: () => import('@/pages/RecipesPage.vue') },
+  { path: '/meal-plan', name: 'MealPlanner', component: () => import('@/pages/MealPlannerPage.vue') },
+  { path: '/pantry', name: 'Pantry', component: () => import('@/pages/PantryPage.vue') },
+  ```
+  Add lazy preload helpers in `MainLayout.vue` similar to lists/expenses.
+- **UI Consistency**: Use Tailwind & existing UI kit components (e.g., `ui/Tabs.vue`, `ui/Dialog.vue`).
+- **Offline Strategy**: Extend `offlineQueue.ts` to support recipe and meal plan mutations.
+
+### 14.3 Migration & Feature Flags
+- Introduce boolean env flag `ENABLE_KITCHEN_SUITE`; wrap router include and `MainLayout` nav link in condition to allow gradual rollout.
+- Provide data migration to back-fill pantry from recent expenses; executed once via Alembic `upgrade()` function referencing `Expense` table.
+
+### 14.4 Testing Plan
+- **Backend**: Unit tests in `tests/api/v1/endpoints/test_recipes.py`, etc., with factory fixtures for recipes & meal plans.
+- **Frontend**: Vitest component tests and Playwright e2e tests (`e2e/mealplanner.spec.ts`) replicating patterns in current `lists.spec.ts`.

+# Home Information Vault — Implementation Roadmap
+
+## 1. Vision & Scope
+A single, secure place for every household to store rarely-needed but mission-critical information ("digital junk drawer"). Once data lives here, switching away is painful, driving long-term retention.
+
+**Primary user stories**
+1. _As a household member_, I can add, view, and update structured facts (e.g. Wi-Fi password, paint colours).
+2. _As a household member_, I can upload and annotate documents (leases, insurance certificates, receipts).
+3. _As a household member_, I receive proactive reminders for expiring warranties/documents.
+4. _As a guest_, I can quickly get the Wi-Fi password via a one-tap share link or QR code.
+
+## 2. Data Model (SQLAlchemy)
+| Model | Fields | Notes |
+|-------|--------|-------|
+| `VaultCategory` | `id`, `group_id`, `name`, `icon` | Logical grouping ("Warranties", "Home Info", "Secure Docs") |
+| `VaultEntry` | `id`, `group_id`, `category_id`, `title`, `description`, `data` (JSONB), `reminder_at` (DateTime), `created_by_id`, `created_at`, `updated_at`, `is_deleted` | Generic row powering all entry types |
+| `VaultAttachment` | `id`, `entry_id`, `file_path`, `file_type`, `file_size`, `thumbnail_path` | S3 / local MinIO storage |
+| `VaultShareToken` | `id`, `entry_id`, `token`, `expires_at`, `created_at` | For guest Wi-Fi share links |
+
+*Use `SoftDeleteMixin` everywhere to support undos.*
+
+## 3. API Design (FastAPI v1)
+*All routes require group membership (reuse `GroupMemberDependency`).*
+
+```
+POST   /vault/categories                 → create category
+GET    /vault/categories                 → list categories
+POST   /vault/entries                    → create entry
+GET    /vault/entries?category_id=       → list entries
+GET    /vault/entries/{id}               → retrieve entry
+PUT    /vault/entries/{id}               → update entry
+DELETE /vault/entries/{id}               → soft-delete entry
+POST   /vault/entries/{id}/attachments   → upload file (multipart)
+DELETE /vault/attachments/{id}           → remove file
+POST   /vault/entries/{id}/share         → generate share token (Wi-Fi)
+GET    /vault/share/{token}              → public redirect or JSON payload
+```
+
+## 4. Services & Background Jobs
+1. **OCR & Manual Fetcher**  
+   – When a `VaultEntry` is created in the "Warranties & Manuals" category with an appliance model number or image, trigger Celery task:  
+   a. Run OCR to extract model no.  
+   b. Scrape/search manufacturer manuals online.  
+   c. Upload PDF into `VaultAttachment`.
+2. **Reminder Scheduler**  
+   – Nightly job checks `reminder_at` ≤ now; for each match push notification & e-mail via existing notification system.
+
+## 5. Permission Model
+- **Group roles**: `owner` ↔ full access; `member` ↔ CRUD but cannot delete categories; guests only via share token.
+- Share tokens are read-only, time-limited, no authentication.
+
+## 6. Front-End (Vue 3 / Pinia)
+### Routes
+- `/vault` → Category list (cards)
+- `/vault/:categoryId` → Entry table/list
+- `/vault/entry/:id` → Detail & edit sheet/dialog
+
+### Components
+- `VaultCategoryCard.vue`
+- `VaultEntryList.vue` (virtual scrolling)
+- `VaultEntryForm.vue` (dynamic fields per category)
+- `VaultAttachmentViewer.vue`
+- `WifiShareDialog.vue` (QR + copy button)
+
+### Store
+`useVaultStore` with actions: `fetchCategories`, `fetchEntries`, `createEntry`, … Similar pattern to lists/expenses.
+
+### UX Polishes
+- Drag-&-drop file uploads, inline previews.
+- Badge showing upcoming expirations.
+
+## 7. Security & Compliance
+- Encrypt sensitive file storage at rest (S3 SSE-KMS / local).  
+- Mask secrets (Wi-Fi, account numbers) until eye icon toggled.  
+- Audit log (`FinancialAuditLog` style) for every change.
+
+## 8. Migration Plan
+1. Alembic migration to create `vault_*` tables.  
+2. Seed default categories for existing groups.  
+3. Deploy backend.  
+4. Roll out UI hidden behind feature flag → beta groups.  
+5. Gather feedback, iterate, GA.
+
+## 9. Estimated Timeline
+| Phase | Duration | Deliverables |
+|-------|----------|--------------|
+| DB & API scaffold | 2 w | Models, CRUD routes, tests |
+| Attachments + S3 | 1 w | Upload service, presigned URLs |
+| OCR + Manual fetch | 1 w | Celery tasks, unit tests |
+| Front-end MVP | 2 w | Category & Entry CRUD screens |
+| Reminders & share links | 1 w | Scheduler, share token endpoints |
+| Polish & Beta | 1 w | UX, accessibility, docs |
+
+_Total ≈ 8 weeks with 1 backend + 1 frontend engineer._
+
+## 10. Compatibility with Existing Codebase
+
+### 10.1 Backend Alignment
+- **Database Session & Dependency Injection**: Use the shared `get_db` dependency from `app.db.session` just like current CRUD routers (see `lists`, `groups`).
+- **Router Pattern**: Follow `/app/api/v1/endpoints/` structure.  Create `vault.py` with `router = APIRouter(prefix="/vault", tags=["Vault"])` mirroring `lists.py` implementation.
+- **CRUD Layer**: Add `crud/vault_entry.py`, `crud/vault_category.py`, etc., inheriting from `CRUDBase` pattern already used across the project.
+- **Schemas**: Place Pydantic models in `schemas/vault.py`, version with `BaseModelOrm` to enable `.from_orm()` like others.
+- **Soft Deletes**: Reuse `SoftDeleteMixin` and central `query_active()` helper so filters are consistent.
+- **Permissions**: Reuse `GroupAccessChecker` dependency (currently used in `items`, `expenses`) ensuring RBAC is enforced uniformly.
+- **File Uploads**: Leverage existing S3 service in `core/` (if none, extend minimal wrapper) used by OCR.
+- **Background Tasks**: Hook Celery tasks into `jobs/` package; scheduler already exists for recurring expenses – add periodic task entry to same Beat schedule.
+
+### 10.2 Front-End Alignment
+- **API Layer**: Extend `services/api.ts` with `vault` endpoints; follow pattern of `groupService.ts` and `expenseService.ts` for generated functions.
+- **State Management**: Implement `stores/vaultStore.ts` mirroring `listDetailStore.ts` (getters for categories, entries, attachments) using Pinia & optimistic updates helpers already present.
+- **Routing**: Add vault routes to `router/routes.ts`, lazy-load components like existing pages. Example:
+  ```ts
+  {
+    path: '/vault',
+    name: 'VaultHome',
+    component: () => import('@/pages/VaultPage.vue'),
+  }
+  ```
+- **i18n**: Add placeholder strings under `i18n/en.json` etc.
+- **UI Components**: Conform to existing design system: reuse `ui/Card.vue`, `Dialog.vue`, `Button.vue`; mount in `layouts/MainLayout.vue` nav with new icon.
+- **Auth Handling**: Vault routes guard with existing `useAuthStore().isAuthenticated` redirecting to `/auth/login` if needed.
+
+### 10.3 Testing Strategy
+- **Backend**: Parametrised pytest cases similar to `tests/api/v1/endpoints/test_lists.py`. Fixture: create group + user, test CRUD and share link token.
+- **Frontend**: Vitest + Testing-Library component tests; e2e via Playwright (similar to `lists.spec.ts`).
+
+---
+
+_This ensures the Vault integrates seamlessly without reinventing infrastructure._

+# Household Management App: Vue + Headless UI Refactor Specification
+
+## Executive Summary
+
+This document outlines a comprehensive refactor strategy to transform the current household management app into a frictionless, conflict-reducing platform using Vue 3 with Composition API and headless UI libraries. The focus is on achieving sub-5-second interactions, zero-ambiguity states, and maximum adoption through radical simplification.
+
+## Core Design Philosophy
+
+### The 3-2-1 Rule
+- **3 seconds**: Maximum time from app open to actionable information
+- **2 taps**: Maximum interaction depth for common actions
+- **1 source of truth**: Every piece of information has exactly one authoritative display
+
+### Friction Elimination Principles
+1. **Cognitive Load Minimization**: Default to the most common choice
+2. **Progressive Disclosure**: Advanced features emerge only when needed
+3. **Optimistic UI**: Show results immediately, sync in background
+4. **Contextual Actions**: Surface relevant actions based on current state
+
+---
+
+## Technical Architecture Overview
+
+### Vue 3 + Headless UI Stack
+- **Vue 3.4+** with Composition API and `<script setup>`
+- **Headless UI Vue** for accessible, unstyled components
+- **Tailwind CSS 3.4+** with custom design tokens
+- **VueUse** for composables and utilities
+- **Pinia** for state management with persistence
+- **Vue Router 4** with lazy loading
+- **Vite** for build tooling and HMR
+
+### State Management Strategy
+- **Global Store Pattern**: Centralized household data with reactive updates

+- Generate conflicts through unclear responsibilities
+
+### New Information Hierarchy
+
+```
+Dashboard (Home) - Single source of truth
+├── Personal Status (Above fold)
+│   ├── My Next Action (1 item max)
+│   ├── My Financial Status (Net balance)
+│   └── Quick Win Suggestion
+├── Universal Actions (FAB)
+│   ├── Add Expense (80% of usage)
+│   ├── Complete Chore (15% of usage)
+│   └── Add to List (5% of usage)
+└── Activity Feed (Social proof)
+    ├── Completions (Positive reinforcement)
+    ├── New Items (Transparency)
+    └── Financial Updates (Trust building)
