+# Error Handling and Recovery Audit
+
+This audit examines the error handling and recovery mechanisms in the application.
+
+## Findings
+
+### 1. Exception Hierarchy Consistency
+
+- **Observation:** The application lacks a consistent exception hierarchy, frequently relying on the generic `\Exception` class.
+- **Impact:** This makes it difficult to differentiate between various error types, leading to less precise error handling and potentially noisy logs.
+- **Recommendation:** Implement a custom exception hierarchy with a base `ApiException` class and more specific exception types.
+
+### 2. Error Boundary Placement
+
+- **Observation:** Error boundaries are not consistently placed, with some code catching exceptions at a low level and others allowing them to bubble up.
+- **Impact:** This can lead to inconsistent error responses and makes it harder to reason about the application's error-handling behavior.
+- **Recommendation:** Establish clear guidelines for where to catch and handle exceptions, and implement a global exception handler to ensure all unhandled exceptions are caught and processed consistently.
+
+### 3. User-Facing Error Messages
+
+- **Observation:** User-facing error messages are a mix of hardcoded strings and translations from a language file, which can lead to an inconsistent tone and style.
+- **Impact:** This can create a jarring user experience and may not always provide helpful information.
+- **Recommendation:** Standardize the creation of user-facing error messages, and ensure they are always clear, concise, and helpful.
+
+### 4. Logging Completeness
+
+- **Observation:** Logging is not always complete, with some `try-catch` blocks failing to log the exceptions they catch.
+- **Impact:** This can make it difficult to debug issues, as important error information may be lost.
+- **Recommendation:** Implement a consistent logging strategy, ensuring that all caught exceptions are logged with sufficient context.
+
+### 5. Recovery Strategies
+
+- **Observation:** The application has limited recovery strategies, with most `try-catch` blocks simply logging the error and returning a generic response.
+- **Impact:** This can lead to a degraded user experience, as the application may not be able to recover from transient errors.
+- **Recommendation:** Implement more robust recovery strategies, such as retrying failed operations or providing fallback functionality.
+
+## Changes Made
+
+To address the issues identified in this audit, the following changes have been made:
+
+1.  **Introduced a Custom Exception Hierarchy:**
+    -   Created a new `src/Core/Exception` directory.
+    -   Defined a base `ApiException` class that extends `\Exception`.
+    -   Created more specific exception classes, such as `AuthorizationException` and `ValidationException`, that extend `ApiException`.
+
+2.  **Implemented a Global Exception Handler:**
+    -   Created a new `src/Core/Exception/Handler.php` file to serve as the application's global exception handler.
+    -   This handler is registered in `src/Core/Boot.php` and is responsible for catching `ApiException` types and generating appropriate JSON responses.
+
+3.  **Refactored Existing Code:**
+    -   The `ManagesTokens` trait was refactored to throw the new `AuthorizationException` instead of the generic `\Exception`.
