+## 2. Control Flow Analysis
+
+### 2.1 Engine::Engine() Constructor - Initialization Flow
+
+**Source**: `engine/lsr/src/Engine.cpp:24-45`
+
+```mermaid

+
+**Critical Paths**:
+| Path ID | Condition | Result | ASIL Impact |
+|---------|-----------|--------|-------------|
+| P1 | DB error at startup | Error state retained | SG2 - Availability |
+| P2 | Texture load failure | LSR_DB_INCONSISTENT | SG1 - Correct Display |

+## 4. Critical Path Analysis
+
+### 4.1 Safety-Critical Execution Paths
+
+| Path ID | Function | Critical Decision | Safety Impact |
+|---------|----------|-------------------|---------------|
+| CP-001 | Engine::Engine | Texture load check | Display availability |
+| CP-002 | Engine::getError | Error priority chain | Error visibility |
+| CP-003 | ReferenceBitmapField::onVerify | Visibility check bypass | Verification control |
+| CP-004 | ReferenceBitmapField::onVerify | Pixel comparison | Corruption detection |
+| CP-005 | Canvas::verify | Texture load | Verification validity |
+| CP-006 | Pool::allocate | Pool integrity check | Memory safety |
+| CP-007 | Pool::deallocate | Double-free check | Memory corruption prevention |
+
+### 4.2 Cyclomatic Complexity
+
+| Function | Complexity | Risk Level |
+|----------|------------|------------|
+| Engine::Engine() | 4 | Low |
+| Engine::getError() | 5 | Low |
+| Pool::allocate() | 3 | Low |
+| Pool::deallocate() | 5 | Low |
+| Pool::checkPool() | 4 | Low |
+| ReferenceBitmapField::onVerify() | 4 | Low |
+| Canvas::verify() | 3 | Low |
+
+All critical functions have cyclomatic complexity ≤ 10, which is acceptable for ASIL D.
+
+---
+
+## 5. Unreachable Code Analysis
+
+### 5.1 Identified Defensive Code
+
+| Location | Code | Status | Justification |
+|----------|------|--------|---------------|
+| Pool::allocate:210 | `else` after `checkPool()` fails | Reachable | Corruption detection path |
+| Pool::deallocate:250 | `else` for corrupted pool | Reachable | Corruption detection path |
+| Engine.cpp:42 | Empty `else` clause | Intentional | MISRA compliance placeholder |
+
+### 5.2 Dead Code Assessment
+
+No unreachable code identified in analyzed functions. All branches are reachable under specific conditions.
+
+---
+
+## 6. Summary
+
+### 6.1 Control Flow Findings
+
+- All critical functions have bounded complexity (≤ 5)
+- No infinite loops possible in analyzed code
+- All error paths terminate with appropriate error codes
+- Multi-level validation in Pool operations
+
+### 6.2 Data Flow Findings
+
+- Clear data ownership throughout render pipeline
+- Error propagation follows defined hierarchy
+- No circular data dependencies
+- Reference bitmap data integrity maintained through verification chain
+
+### 6.3 Recommendations
+
+1. **Pool::checkPool()** should be called before every pool operation (currently implemented)
+2. **Error aggregation** correctly prioritizes engine-level errors
+3. **Verification bypass** for invisible fields is intentional and documented

+## 1. Introduction
+
+### 1.1 Purpose
+
+This document presents the Hazard Analysis and Risk Assessment (HARA) for the Luxoft Safe Renderer (LSR) software component. The HARA is performed in accordance with ISO 26262:2018 Part 3 to:
+
+1. Identify and classify hazardous events
+2. Assess associated risks using Severity, Exposure, and Controllability
+3. Determine Automotive Safety Integrity Levels (ASIL)
+4. Derive safety goals to prevent or mitigate hazardous events
+
+### 1.2 Scope
+
+This HARA covers the Luxoft Safe Renderer as a Safety Element out of Context (SEooC) intended for integration into automotive HMI systems. The scope includes:
+
+**In Scope:**
+- Core rendering engine (`engine/lsr`)
+- Database management (`engine/database`)
+- Display management (`engine/display`)
+- Frame handling (`engine/framehandler`)
+- Common utilities (`engine/common`)
+- Graphics Interface Layer (`gil`)
+- Platform Interface Layer (`pil`)
+
+**Out of Scope:**
+- Simulation modules (`simu/`)
+- Third-party test frameworks (`3rdparty/`)
+- Customer HMI application code
+- Hardware platform specifics
+
+### 1.3 SEooC Assumptions
+
+As a Safety Element out of Context, the following assumptions apply:
+
+| ID | Assumption | Rationale |
+|----|------------|-----------|
+| A1 | LSR is integrated into a vehicle display system (instrument cluster, head unit) | Primary deployment context |
+| A2 | LSR renders safety-critical visual indicators (warning lamps, telltales) | Core safety function |
+| A3 | Driver relies on displayed information for safe vehicle operation | Justifies safety-critical classification |
+| A4 | Integration environment provides compliant hardware and platform services | SEooC boundary assumption |
+| A5 | GIL and PIL implementations are provided by integrator with appropriate ASIL | Interface compliance |
+
+---
+
+## 2. Item Definition
+
+### 2.1 Item Description
+
+The Luxoft Safe Renderer (LSR) is a safety-critical HMI rendering engine designed for automotive applications. It provides:
+
+1. **Rendering of Safety-Critical Graphics**: Display warning indicators, telltales, and safety-related visual information
+2. **Video Output Verification**: Compare rendered output against reference bitmaps to detect corruption
+3. **Fallback Rendering**: Take over display duties if the main HMI system fails
+4. **Deterministic Operation**: Pre-allocated memory, bounded execution times

+## 1. Introduction
+
+### 1.1 Purpose
+
+This Safety Analysis Report presents the Failure Mode and Effects Analysis (FMEA) for the Luxoft Safe Renderer (LSR). The analysis identifies:
+
+1. Potential failure modes for each software component
+2. Effects of failures at local, system, and vehicle levels
+3. Detection mechanisms for each failure mode
+4. Mitigation strategies and safety mechanisms
+5. Diagnostic coverage calculations
+
+### 1.2 Scope
+
+This analysis covers the core LSR software components within the certification boundary:
+
+| Module | Description | Safety Relevance |
+|--------|-------------|------------------|
+| `engine/lsr` | Main engine facade | High - orchestrates safety functions |
+| `engine/database` | Configuration and bitmap management | High - data integrity |
+| `engine/display` | Display manager and texture cache | High - rendering correctness |
+| `engine/framehandler` | Widget hierarchy management | High - rendering logic |
+| `engine/common` | Safety utilities (Pool, Assertions) | Critical - foundational safety |
+| `gil` | Graphics Interface Layer | High - graphics output |
+| `pil` | Platform Interface Layer | High - platform services |
+
+### 1.3 Analysis Method
+
+The FMEA follows ISO 26262-9 Annex B methodology:
+1. System decomposition into components and functions
+2. Identification of failure modes per function
+3. Assessment of failure effects
+4. Determination of detection mechanisms
+5. Calculation of diagnostic coverage
+6. Mapping to safety goals and requirements

+| Tool Category | Purpose |
+|---------------|---------|
+| Coverity | Static analysis (existing annotations found) |
+| Manual Review | MISRA/AUTOSAR compliance check |
+| This Document | Consolidated findings |
+

+
+## 2. Executive Summary
+
+### 2.1 Overall Assessment
+
+| File | MISRA Violations | AUTOSAR Violations | Severity |
+|------|------------------|-------------------|----------|
+| Pool.h | 12 (8 justified, 4 advisory) | 6 | Medium |
+| ReferenceBitmapField.cpp | 3 | 2 | Low |

+
+## 3. Pool.h Analysis
+
+### 3.1 File Information
+
+| Attribute | Value |
+|-----------|-------|
+| Path | `engine/common/api/Pool.h` |
+| Lines of Code | 373 |
+| Functions | 14 |
+| Complexity | Low-Medium |
+| Safety Relevance | **High** - Memory management |
+
+### 3.2 MISRA C++:2008 Findings
+
+#### 3.2.1 Rule 0-1-2: Unused Value (Advisory)
+
+**Location**: Line 169
+```cpp
+// coverity[misra_cpp_2008_rule_0_1_2_violation] Template parameter
+static const std::size_t lastIndex = (PoolSize - 1U);
+```
+
+**Finding**: Variable appears unused due to template instantiation path.
+
+**Status**: ✅ **JUSTIFIED** - Documented deviation. Value used in subsequent loop.
+
+**ASIL D Impact**: None - Compile-time constant, no runtime effect.
+
+---
+
+#### 3.2.2 Rule 5-0-15: Pointer Arithmetic (Required)
+
+**Locations**: Lines 178, 180, 186, 282, 291
+
+```cpp
+// Line 178, 180
+Node& currentNode = m_pFreeList[i];
+currentNode.body.next = &m_pFreeList[i + 1U];
+
+// Line 282
+return (tmpPtr >= m_storage) && (tmpPtr < (m_storage + sizeof(m_storage)));
+
+// Line 291
+const std::ptrdiff_t length = (tmpPtr - m_storage);
+```
+
+**Finding**: Pointer arithmetic used on array elements.
+
+**Status**: ✅ **JUSTIFIED** - Required for memory pool implementation. Array indexing is bounded by compile-time constants.
+
+**Mitigation**:
+- PoolSize is compile-time checked (P_STATIC_ASSERT)
+- Bounds checking in `checkObjectIsInsideStorage()`
+- All pointer arithmetic operates within m_storage bounds
+
+**ASIL D Impact**: Low - Bounded pointer arithmetic with static verification.
+
+---
+
+#### 3.2.3 Rule 5-2-7: Pointer Cast to Pointer (Required)
+
+**Location**: Line 172
+```cpp
+// coverity[misra_cpp_2008_rule_5_2_7_violation]
+m_pFreeList = reinterpret_cast(m_storage);
+```
+
+**Finding**: `reinterpret_cast` from `U8*` to `Node*`.
+
+**Status**: ⚠️ **DEVIATION REQUIRED** - Essential for memory pool implementation.
+
+**Justification**:
+1. m_storage is correctly sized: `U8 m_storage[PoolSize * sizeof(Node)]`
+2. Alignment handled by AlignValue template parameter
+3. Static assertion validates alignment is power of 2
+4. Node layout is well-defined (standard layout type)
+
+**ASIL D Impact**: Medium - Requires deviation documentation per ISO 26262-6.
+
+**Recommended Action**: Add to deviation log with formal justification.
+
+---
+
+#### 3.2.4 Rule 5-2-8: Cast Removes Const/Volatile (Required)
+
+**Locations**: Lines 280, 289, 300, 326, 352
+
+```cpp
+// Line 280
+const U8* const tmpPtr = reinterpret_cast(ptr);
+
+// Line 300
+const Node* const pNode = reinterpret_cast(ptr);
+```
+
+**Finding**: `reinterpret_cast` usage for type conversion.
+
+**Status**: ✅ **JUSTIFIED** - Const-correctness maintained; casts do not remove const.
+
+**Note**: Coverity annotation indicates false positive - casts ADD const, not remove it.
+
+**ASIL D Impact**: None - Const safety preserved.
+
+---
+
+#### 3.2.5 Rule 9-3-2: Member Functions Return Non-const Handle (Required)
+
+**Location**: Line 215
+```cpp
+// coverity[misra_cpp_2008_rule_9_3_2_violation]
+return pData;
+```
+
+**Finding**: Function returns non-const pointer to internal data.
+
+**Status**: ✅ **JUSTIFIED** - Intentional API design. Caller needs write access to allocated memory.
+
+**ASIL D Impact**: None - Documented API behavior.
+
+---
+
+#### 3.2.6 Rule 9-5-1: Union Usage (Required)
+
+**Location**: Lines 125-133
+```cpp
+// coverity[misra_cpp_2008_rule_9_5_1_violation]
+union NodeBody
+{
+ U8 data[impl::NodeDataLength::value];
+ Node* next;
+};
+```
+
+**Finding**: Union used in safety-critical code.
+
+**Status**: ⚠️ **DEVIATION REQUIRED** - Essential for memory pool efficiency.
+
+**Justification**:
+1. Union members never accessed simultaneously
+2. `data[]` used when node is allocated (busy)
+3. `next` pointer used when node is free
+4. State tracked by marker field (0xAA/0x55)
+5. Only one interpretation valid at any time based on marker
+
+**Safety Argument**:
+- Marker pattern (0xAA free, 0x55 busy) enforces exclusive access
+- Double-free detection prevents invalid union interpretation
+- checkPool() validates marker integrity
+
+**ASIL D Impact**: Medium - Requires formal deviation per ISO 26262-6:2018 Table 1.
+
+---
+
+### 3.3 AUTOSAR C++14 Findings
+
+#### 3.3.1 A5-2-4: reinterpret_cast Shall Not Be Used (Required)
+
+**Locations**: Lines 172, 280, 289, 300, 326, 352
+
+**Finding**: Multiple uses of `reinterpret_cast`.
+
+**Status**: ⚠️ **DEVIATION REQUIRED**
+
+**Justification**: Same as MISRA 5-2-7/5-2-8.
+
+---
+
+#### 3.3.2 A8-4-7: Parameter in/out Shall Be Documented (Required)
+
+**Location**: Line 75
+```cpp
+void* allocate(LSREngineError& error);
+```
+
+**Finding**: `[out]` annotation present in documentation, compliant.
+
+**Status**: ✅ **COMPLIANT**
+
+---
+
+#### 3.3.3 A9-5-1: Unions Shall Not Be Used (Required)
+
+**Location**: Lines 125-133
+
+**Finding**: Union NodeBody defined.
+
+**Status**: ⚠️ **DEVIATION REQUIRED** - Same justification as MISRA 9-5-1.
+
+---
+
+#### 3.3.4 A12-1-1: Explicit Constructors for Single-Argument (Required)
+
+**Finding**: Pool constructor has no single-argument form.
+

+
+---
+
+### 3.4 Safety Mechanism Analysis
+
+| Mechanism | Implementation | ASIL D Compliance |
+|-----------|----------------|-------------------|
+| Corruption Detection | checkPool(), checkMarker() | ✅ Meets SG4 |
+| Bounds Checking | checkObjectIsInsideStorage() | ✅ |
+| Double-Free Detection | checkObjectIsFree() | ✅ |
+| Memory Zeroing | memset on deallocate | ✅ Defense-in-depth |
+| Loop Termination | nodeCounter <= PoolSize | ✅ Prevents infinite loops |
+| Static Assertions | P_STATIC_ASSERT | ✅ Compile-time validation |
+
+### 3.5 Complexity Metrics
+
+| Function | Cyclomatic Complexity | Lines | Risk |
+|----------|----------------------|-------|------|
+| Pool() | 3 | 27 | Low |
+| allocate() | 3 | 25 | Low |
+| deallocate() | 5 | 38 | Low |
+| checkPool() | 3 | 10 | Low |
+| checkFreeList() | 5 | 37 | Low |
+| isAllocated() | 1 | 4 | Low |
+
+All functions have complexity ≤ 10, compliant with ISO 26262 ASIL D.

+
+## 4. ReferenceBitmapField.cpp Analysis
+
+### 4.1 File Information
+
+| Attribute | Value |
+|-----------|-------|
+| Path | `engine/framehandler/src/ReferenceBitmapField.cpp` |
+| Lines of Code | 92 |
+| Functions | 6 |
+| Complexity | Low |
+| Safety Relevance | **High** - Pixel verification |
+
+### 4.2 MISRA C++:2008 Findings
+
+#### 4.2.1 Rule 0-1-9: Dead Code (Required)
+
+**Location**: Line 57-59
+```cpp
+void ReferenceBitmapField::onDraw(Canvas& /* dst */, const Area& /* rect */) const
+{
+}
+```
+
+**Finding**: Empty function body.
+
+**Status**: ✅ **COMPLIANT** - Intentional no-op for verification-only field. Parameters commented per MISRA guidance.
+
+**Safety Rationale**: ReferenceBitmapField intentionally does not draw; it only verifies existing pixels.
+
+---
+
+#### 4.2.2 Rule 5-0-15: Pointer Dereference After NULL Check (Required)
+
+**Location**: Lines 72-73
+```cpp
+const StaticBitmap bitmap = m_pDatabase->getBitmap(m_bitmapId);
+m_verified = dst.verify(bitmap, rect);
+```
+
+**Finding**: m_pDatabase dereferenced without explicit NULL check in onVerify().
+
+**Analysis**:
+- m_pDatabase set in setup() at line 45
+- setup() called before onVerify() per API contract
+- ASSERT in constructor validates m_pDdh
+
+**Status**: ⚠️ **ADVISORY** - Consider defensive NULL check.
+
+**Recommendation**:
+```cpp
+if (m_pDatabase != NULL)
+{
+ const StaticBitmap bitmap = m_pDatabase->getBitmap(m_bitmapId);
+ m_verified = dst.verify(bitmap, rect);
+}
+else
+{
+ // Handle error - should not occur if API used correctly
+ m_verified = false;
+}
+```
+
+**ASIL D Impact**: Low - Protected by API contract but defensive check recommended.
+
+---
+
+#### 4.2.3 Rule 6-4-2: All If-Else-If Shall Terminate with Else (Required)
+
+**Location**: Lines 66-81
+```cpp
+if (m_verified)
+{
+ clearVerificationErrors();
+}
+else
+{
+ // ...
+ if (!m_verified)
+ {
+ if (m_verificationErrors < U32_MAX)
+ {
+ ++m_verificationErrors;
+ }
+ // Missing else for inner if
+ }
+}
+```
+
+**Finding**: Inner `if` at line 76 has no `else` clause.
+
+**Status**: ✅ **COMPLIANT** - No action needed when counter is saturated; behavior is intentional (counter stays at max).
+
+**Safety Rationale**: Counter saturation is defensive measure against overflow. Documentation added in CFA analysis.
+
+---
+
+### 4.3 AUTOSAR C++14 Findings
+
+#### 4.3.1 A7-1-1: Constexpr Where Possible (Advisory)
+
+**Finding**: No constexpr opportunities identified - all functions require runtime data.
+
+**Status**: ✅ **COMPLIANT**
+
+---
+
+#### 4.3.2 A8-5-2: Braced Initialization (Advisory)
+
+**Location**: Lines 36-38
+```cpp
+, m_bitmapId(0U)
+, m_verificationErrors(0U)
+, m_verified(false)
+```
+
+**Finding**: Uses parenthesis initialization, not braced initialization.
+
+**Status**: ✅ **COMPLIANT** - Parenthesis initialization acceptable for primitive types.
+
+---
+
+### 4.4 Safety Mechanism Analysis
+
+| Mechanism | Implementation | ASIL D Compliance |
+|-----------|----------------|-------------------|
+| Visibility Check | !isVisible() early return | ✅ Intentional bypass |
+| Error Counter | m_verificationErrors with saturation | ✅ Overflow protection |
+| Counter Clear | clearVerificationErrors() | ✅ State reset |
+| Assertion | ASSERT(NULL != m_pDdh) | ✅ Constructor validation |
+
+### 4.5 Complexity Metrics
+
+| Function | Cyclomatic Complexity | Lines | Risk |
+|----------|----------------------|-------|------|
+| ReferenceBitmapField() | 1 | 10 | Low |
+| setup() | 2 | 6 | Low |
+| setupBitmapExpr() | 2 | 5 | Low |
+| onDraw() | 1 | 3 | Low |
+| onVerify() | 4 | 24 | Low |
+| clearVerificationErrors() | 1 | 4 | Low |
+
+All functions have complexity ≤ 10, compliant with ISO 26262 ASIL D.

+## 5. Deviation Summary
+
+### 5.1 Required Deviations
+
+| ID | Rule | Location | Justification | Risk Mitigation |
+|----|------|----------|---------------|-----------------|
+| DEV-001 | MISRA 5-2-7 | Pool.h:172 | Memory pool requires cast to Node* | Alignment validated, bounds checked |
+| DEV-002 | MISRA 9-5-1 | Pool.h:125 | Union for memory efficiency | Marker-based state tracking, exclusive access |
+| DEV-003 | AUTOSAR A5-2-4 | Pool.h:multiple | Same as DEV-001 | Same as DEV-001 |
+| DEV-004 | AUTOSAR A9-5-1 | Pool.h:125 | Same as DEV-002 | Same as DEV-002 |
+
+### 5.2 Deviation Documentation Template
+
+```
+DEVIATION ID: DEV-001
+RULE: MISRA C++:2008 Rule 5-2-7
+SEVERITY: Required
+LOCATION: engine/common/api/Pool.h, Line 172
+
+DESCRIPTION:
+Use of reinterpret_cast to convert U8* storage to Node* pointer.
+
+JUSTIFICATION:
+The Pool template implements a pre-allocated memory pool where storage
+is declared as U8[] for size control and reinterpreted as Node[] for
+type-safe access. This pattern is essential for:
+1. Avoiding dynamic memory allocation (ASIL D requirement)
+2. Ensuring deterministic memory layout
+3. Enabling corruption detection via marker fields
+
+SAFETY ARGUMENT:
+- Storage size computed as PoolSize * sizeof(Node)
+- Alignment enforced via AlignValue template parameter
+- P_STATIC_ASSERT validates alignment is power of 2
+- Node is standard-layout type
+- All pointer operations bounded by checkObjectIsInsideStorage()
+
+RISK ASSESSMENT:
+- Risk Level: Low
+- Likelihood: Very Low (compile-time verification)
+- Impact: Memory corruption (mitigated by checkPool())
+
+APPROVAL:
+- Safety Engineer: _________________ Date: _________
+- Project Lead: _________________ Date: _________

+## 6. Verification Methods
+
+### 6.1 Requirements-Based Testing
+
+Each TSR must have at least one test case:

+
+For each public interface:
+
+```cpp
+// Example interface test
+TEST_F(EngineTest, RenderInterface) {
+ // Pre-condition
+ ASSERT_TRUE(engine.getError().getValue() == LSR_NO_ENGINE_ERROR);
+
+ // Execute
+ bool result = engine.render();
+
+ // Post-condition
+ EXPECT_TRUE(result);
+ EXPECT_EQ(engine.getError().getValue(), LSR_NO_ENGINE_ERROR);
+}
+```
+
+### 6.3 Fault Injection Testing
+
+| Fault Type | Injection Method | Verification |
