+# MeshiTrack ESLint Remediation & Clean-up Plan
+
+This document establishes a highly structured, quantitative, and actionable plan to resolve the remaining **ESLint violations** across the MeshiTrack monorepo. Following the auto-formatting runs (which successfully wiped out all 279 Prettier warnings), we have mapped out all remaining violations into distinct, manageable categories.

+
+## 📅 2. Stage-by-Stage Remediation Strategy
+
+### 🛠️ Stage 1: Rule Refinement (Remediation: ~120 Errors Resolved)
+Before refactoring active files, we fine-tune our rules to represent real-world Javascript/TypeScript practices:
+1. **Allow `PascalCase` on variables**: We have already enabled `PascalCase` for variables in both packages, allowing React component functions (e.g. `const TopBar = ...`) and database model objects (e.g. `const UserModel = ...`) to parse correctly.
+2. **Exclude dynamic API/Database keys**: We will configure `@typescript-eslint/naming-convention` to ignore property names containing leading/trailing underscores (like `_id` and `__v`) or specific HTTP headers in controllers.
+
+---
+
+### 📝 Stage 2: Explicit Boundary Return Types (Remediation: 215 Errors Resolved)
+To prevent type-drift, we will add explicit return signatures to the codebase:
+1. **Service and Repository Boundaries**: Add explicit return types to all public methods in all services (e.g., `Promise<ShoppingListDocument[]>`, `Promise<void>`).
+2. **Fastify Route Handlers**: Specify return types or configure ESLint to allow implicit handler return values since Fastify structures routing objects automatically.
+
+---
+
+### 🛡️ Stage 3: Unsafe-`any` Eradication (Remediation: 377 Errors Resolved)
+The largest source of logic leaks resides in un-typed values and `as any` casting:
+1. **Shift to `unknown` for Boundary Payloads**: For Fastify dynamic requests (`request.body`, `request.params`) and Next.js dynamic states, specify types as `unknown` and parse them safely via **Zod schemas**.
+2. **Standardize Test Suite Mocks**: Replace `as any` mock variables in unit tests with type-safe mock generators or `Partial<T>` objects (e.g. using `vi.mocked()` correctly).
+
+---
+
+### ⚡ Stage 4: Floating Promises & misuses (Remediation: 30 Errors Resolved)
+1. **Await floating promises**: Add correct `await` statements to database connections and route registrations.
+2. **Explicit Background Tasks**: Mark intentional background hooks (like event logs) with `void` (e.g. `void this.logEvent(...)`) to document intention.
+
+---
+
+### 🧱 Stage 5: Structural Class Member Ordering (Remediation: 19 Errors Resolved)
+1. Organize the 19 classes failing the ordering rule to place fields at the top, followed by constructors, followed by public methods, followed by private methods.

+# MeshiTrack Monorepo Clean-up Blueprint
+
+This playbook maps out the precise, incremental, batch-by-batch process to refactor all remaining active modules in both `@meshitrack/api` and `@meshitrack/web` to achieve complete ESLint compliance under our strict new guidelines, while keeping our **100.00% test coverage** pristine.
+
+---
+
+## 🚀 The Core Refactoring Strategy
+
+For every class/module we clean up, we follow the established **Shopping Lists Reference Standard**:
+1. **Repositories**:
+   * Add explicit type parameter annotations for return values (e.g. `: Promise<Document | null>`).
+   * Put private helper methods at the very bottom (under public methods) to satisfy `@typescript-eslint/member-ordering`.
+   * Type query filters explicitly rather than using `any`.
+2. **Services**:
+   * Keep class properties explicit and `readonly` (e.g. `private readonly repository: Repository`).
+   * Add explicit return signatures (e.g. `: Promise<ShoppingListDocument>`).
+   * Avoid `any` completely; use precise casts (e.g. `as ServingUnit`) or type guards.
+3. **Routes**:
+   * Cast Fastify inputs explicitly (`request.params as { ... }` and `request.body as ...`).
+   * Annotate serialization return contracts explicitly (e.g. `serializeList(doc: Document): SerializedContract`).
+   * Wrap WebSocket handshakes or un-typed third party plugins in local ESLint overrides.

+# MeshiTrack Coding Style & Engineering Guidelines
+
+This document establishes the official coding standards, architectural paradigms, and TypeScript guidelines for the MeshiTrack monorepo. These guidelines are designed to enforce clean, testable, object-oriented codebases with pristine type-safety under strict quality gates.
+
+---
+
+## 🏛️ 1. Encapsulation & Class Member Accessibility
+
+To ensure clear visibility boundaries, clean interfaces, and easy maintainability:
+
+1. **Mandatory Accessibility Modifiers**: Every field, constructor, and method in a class must explicitly declare its accessibility modifier (`public`, `protected`, or `private`).
+2. **Mandate Explicit Fields**: Classes that participate in dependency injection (e.g. Services, Repositories, Providers) must explicitly declare their properties at the class level rather than relying on TypeScript constructor parameter properties.
+3. **Class Member Ordering**: Group class members in a predictable sequence:
+   * Static Fields (Public -> Protected -> Private)
+   * Instance Fields (Public -> Protected -> Private)
+   * Constructor
+   * Public Methods
+   * Protected Methods
+   * Private Methods
+
+### Example:
+```typescript
+export class ShoppingListsService {
+  // 1. Explicit, readonly instance properties
+  private readonly shoppingListsRepository: ShoppingListsRepository;
+
+  // 2. Explicit constructor receiving DI payload
+  public constructor({ shoppingListsRepository }: Deps) {
+    this.shoppingListsRepository = shoppingListsRepository;
+  }
+
+  // 3. Public class methods
+  public async list(householdId: string): Promise<ShoppingListDocument[]> {
+    return this.shoppingListsRepository.list(householdId);
+  }
+}
+```
+
+---
+
+## 🛡️ 2. Boundary Types & Return Types
+
+To prevent type-drift across software boundaries:
+
+1. **Explicit Return Types on Boundary Functions**: All public methods of class instances (Services, Repositories, Providers) and all exported module functions must explicitly declare their return types.
+2. **Relegate Inference to Callbacks**: Local, inline variables and anonymous arrow callbacks (e.g. within array map/filter functions) may utilize automatic type inference for conciseness.
+
+### Example:
+```typescript
+// 🟢 Good: Explicitly defined return type on the boundary method
+public async list(householdId: string): Promise<ShoppingList[]> {
+  const lists = await this.shoppingListsRepository.list(householdId);
+  return lists.filter(item => item.status === 'active'); // Inline inference is okay
+}
+```
+
+---
+
+## 🚫 3. Eradicating `any` & Enforcing Type-Safety
+
+TypeScript's `any` type compromises the integrity of our codebase and makes refactoring fragile. 
+
+1. **No Explicit `any`**: The use of explicit `any` is strictly prohibited throughout the codebase, including in test files.
+2. **Restrict Unsafe Operations**: We enforce strict type-checked rules to prevent the propagation of `any`:
+   * Assigning an `any` to a variable/property is blocked (`@typescript-eslint/no-unsafe-assignment`).
+   * Reading a property off of an `any` is blocked (`@typescript-eslint/no-unsafe-member-access`).
+   * Invoking functions typed as `any` is blocked (`@typescript-eslint/no-unsafe-call`).
+   * Returning an `any` from a function is blocked (`@typescript-eslint/no-unsafe-return`).
+3. **Prefer `unknown` for Dynamic Inputs**: Any unchecked external input (e.g., API payloads, database responses, dynamic JSON files) must be typed as `unknown` and validated at the boundary using **Zod schemas** or type guards.
+4. **Type-Safe Mocking**: Instead of casting mocks with `as any`, use highly targeted partial types or precise mocks.
+
+---
+
+## 🏷️ 4. Naming Conventions & File Structures
+
+Uniform naming conventions prevent conflicts and reduce cognitive load:
+
+1. **Directories**: Lowercase `kebab-case` (e.g., `shopping-lists/`).
+2. **Files**: `PascalCase` matching the primary class or component exported in the file (e.g., `ShoppingListsService.ts`), ensuring class name and file name are aligned.
+3. **Identifiers**:
+   * **PascalCase**: Classes, Interfaces, Type Aliases, Enums.
+   * **camelCase**: Properties, Methods, Variables, Parameters, Functions.
+   * **UPPER_CASE**: Top-level static read-only constants.
+4. **Prohibit Hungarian Notation**: Do not prefix interfaces with `I` (e.g. write `ShoppingListsRepository`, NOT `IShoppingListsRepository`).
+
+---
+
+## 🛑 5. Structured Domain Exceptions
+
+Exception mapping must be uniform, semantic, and highly testable:
+
+1. **Prohibit Generic `Error` Throwing**: The service and business layers must never throw generic `new Error('message')` for operational domain failures. 
+2. **Domain-Specific Exceptions**: Throw subclasses of `AppError` (e.g. `NotFoundError`, `ConflictError`, `BadRequestError`) containing semantic properties like status codes and optional structured sub-details.
+3. **Prevent Stack Leakage**: Our custom exceptions map directly to HTTP responses in central middleware, ensuring internal database schemas or runtime details are never leaked to external clients.
+
+### Example:
+```typescript
+// 🟢 Good: Highly testable, structured domain-level exception
+if (!updated) {
+  throw new NotFoundError('Shopping list not found');
+}
+```
+
+---
+
+## 🧱 6. OOP vs. Functional Boundaries
+
+We keep class-based OOP strictly segregated from pure stateless helpers:
+
+1. **Stateful Layers -> Classes**: Services, Repositories, and Providers must be class-based to properly encapsulate state, DI, and persistence hooks.
+2. **Stateless Operations -> Standalone Pure Functions**: Math utilities, date/string formatters, and mapping helpers must be written as standalone, exported functions in pure modules.
+3. **No Utility Classes**: Do not write static utility classes (classes composed solely of static helper methods). Use direct ES module exports.
+
+---
+
+## ⚡ 7. Asynchronous Programming Integrity
+
+To prevent background crashes, memory leaks, and silent failures:
+
+1. **Mandate `async/await`**: Use `async/await` exclusively instead of Promise chains (`.then()`, `.catch()`).
+2. **Block Floating Promises**: Every Promise must be `await`ed or returned.
+3. **Explicit Voiding for Intentional Background Tasks**: If a task must run in the background (fire-and-forget), it must be explicitly voided (e.g. `void this.trackEvent()`) and handle its exceptions internally to prevent uncaught runtime rejections.
