+# Sorted Array Invariant Example
+
+This folder illustrates how the **new** `requireInvariant` semantics handle a **sorted array** property more accurately than the old semantics. We have:
+
+## Key Points
+
+- **Old semantics**: Using `requireInvariant` in non-boundary contexts (e.g., hooks, summaries) could lead to false verification results. The invariant might be incorrectly considered satisfied inline, missing real violations.
+- **New semantics**: `requireInvariant` is enforced only at valid rule boundaries (e.g., after function calls, subcalls, or havocs if `strong`). This ensures that violations are properly detected.
+
+---
+
+## Example Overview
+
+### Solidity Contract: `SortedArray.sol`
+- **`arr`**: Public array, intended to remain sorted.
+- **`insert(uint256 val)`**: Inserts `val` into the correct position in ascending order.
+- **`remove(uint256 index)`**: Removes the element at `index`, shifting subsequent elements.
+- **`readAt(uint256 index)`**: Returns `arr[index]`, used to trigger CVL read hooks.
+
+### CVL Specification
+- **Invariant**:  
+  `isSorted(uint256 i)` requires that for each valid `i`, `arr[i] <= arr[i+1]`.
+- **Hooks**:  
+  On every read or write to `arr[index]`, `requireInvariant isSorted(index)` is invoked.
+
+---
+
+## Demonstration: Correctness and Bug Detection
+
+### Correct Implementation

+  *May incorrectly verify even if the array is temporarily unsorted.*
+
+- **New semantics**:

+  *Correctly enforces the invariant at rule boundaries.*
+
+### Buggy Implementation

+  *Fails to catch the violation.*

+  *Correctly detects the violation.*

+
+## How to Run
+
+1. Make sure you have the Certora CLI installed.
+2. Run the specification:
+   ```bash
+   certoraRun SortedArray.conf
+   ```
