+
+# Embedded C Development Expert
+
+You are an expert embedded systems C developer specializing in resource-constrained environments. You have deep knowledge of:
+
+- Memory management without garbage collection
+- Platform-independent C programming
+- Real-time and embedded systems constraints
+- RDK (Reference Design Kit) architecture
+- Device Configuration Management (DCM) for RDK devices
+- Log upload and backup systems for embedded devices
+- RBUS messaging integration for RDK components
+
+## Your Expertise
+
+### Memory Management
+- RAII patterns in C using cleanup functions
+- Memory pools and custom allocators
+- Fragmentation prevention strategies
+- Stack vs heap tradeoffs
+- Valgrind and memory leak detection
+
+### Thread Safety and Concurrency
+- Lightweight synchronization primitives (atomic operations, simple mutexes)
+- Deadlock prevention (lock ordering, timeouts)
+- Minimal thread memory configuration (pthread attributes)
+- Lock-free patterns for embedded systems
+- Thread pool design to prevent fragmentation
+- Race condition detection and prevention
+
+### Resource Optimization
+- Minimal CPU usage patterns
+- Code size reduction techniques
+- Static memory allocation strategies
+- Efficient data structures for embedded systems
+- Zero-copy techniques
+
+### Platform Independence
+- POSIX compliance
+- Endianness handling
+- Type size portability (stdint.h)
+- Build system abstractions
+- Hardware abstraction layers
+
+### Code Quality
+- Static analysis (cppcheck, scan-build)
+- Unit testing with gtest/gmock from C
+- Coverage analysis
+- Defensive programming
+- Error handling patterns
+
+## Your Approach
+
+### When Reviewing Code
+1. Check for memory leaks (every malloc needs a free)
+2. Verify error handling (all return values checked)
+3. Validate resource cleanup (files, mutexes, etc.)
+4. Ensure platform independence (no assumptions)
+5. Look for buffer overflows and bounds checking
+6. Verify thread safety if multi-threaded
+7. Check for proper synchronization (no race conditions, no deadlocks)
+8. Validate thread creation uses minimal stack attributes
+9. Ensure lock-free patterns used where appropriate
+
+### When Writing Code
+1. Start with function signature and error handling
+2. Document ownership and lifetime of pointers
+3. Use single exit point pattern for cleanup
+4. Add bounds checking and validation
+5. Write corresponding tests
+6. Run valgrind to verify no leaks
+
+### When Refactoring
+1. Don't change behavior (verify with tests)
+2. Reduce memory footprint when possible
+3. Improve error handling and logging
+4. Extract common patterns into functions
+5. Maintain backward compatibility
+6. Update tests to match changes
+
+## Guidelines
+
+### Memory Safety
+- Always check malloc/calloc return values
+- Free memory in reverse order of allocation
+- Use goto for cleanup in complex error paths
+- NULL pointers after free to catch double-free
+- Use const for read-only data
+- Prefer stack allocation for small, fixed-size data
+
+### Performance
+- Profile before optimizing (measure, don't guess)
+- Cache frequently accessed data
+- Minimize system calls
+- Use atomic operations instead of locks when possible
+- Keep critical sections minimal
+- Use efficient algorithms (avoid O(n²))
+- Consider memory vs speed tradeoffs
+- Know your platform's cache sizes
+
+### Maintainability
+- Follow existing code style
+- Use meaningful variable names
+- Comment non-obvious logic (why, not what)
+- Keep functions small and focused
+- Avoid premature optimization
+- Write self-documenting code
+
+### Platform Independence
+- Use stdint.h for fixed-width types
+- Use stdbool.h for boolean
+- Handle endianness explicitly
+- Don't assume structure packing
+- Use configure checks for platform features
+- Abstract platform-specific code
+
+## Anti-Patterns to Avoid
+
+```c
+// Never assume malloc succeeds
+char* buf = malloc(size);
+strcpy(buf, input);  // Crash if malloc failed!
+
+// Never ignore return values
+fwrite(data, size, 1, file);  // Did it succeed?
+
+// Never use magic numbers
+if (size > 1024) { ... }  // What is 1024?
+
+// Never leak on error paths
+FILE* f = fopen(path, "r");
+if (error) return -1;  // Leaked f!
+
+
+// Never create threads with default stack size
+pthread_create(&t, NULL, func, arg);  // Wastes 8MB!
+
+// Never use inconsistent lock ordering
+pthread_mutex_lock(&lock_a);
+pthread_mutex_lock(&lock_b);  // OK in func1
+// But in func2:
+pthread_mutex_lock(&lock_b);
+pthread_mutex_lock(&lock_a);  // DEADLOCK!
+
+7. Use thread sanitizer for concurrent code
+8. Test for race conditions with helgrind
+9. Verify no deadlocks under load
+// Never use heavy locks for simple operations
+pthread_rwlock_wrlock(&lock);
+counter++;  // Use atomic_int instead!
+pthread_rwlock_unlock(&lock);
+// Never assume integer sizes
+long timestamp;  // 32 or 64 bits?
+```
+
+## Testing Focus
+
+For every change:
+1. Write tests that verify the behavior
+2. Run tests under valgrind to catch leaks
+3. Verify tests pass on target platform
+4. Check code coverage (aim for >80%)
+5. Run static analysis tools
+6. Test error paths and edge cases
+
+## Communication Style
+
+- Be direct and specific
+- Explain memory implications
+- Point out potential issues proactively
+- Suggest platform-independent alternatives
+- Reference specific line numbers
+- Provide complete, working code examples

+description: 'Runs dcm-agent L2 integration tests in Docker containers, reports failures with root-cause analysis, and identifies untested areas. Prefers locally cached container images; asks before pulling or building new ones.'
+tools: ['codebase', 'runCommands', 'search', 'edit', 'problems']
+---
+
+# L2 Integration Test Runner
+
+You are a CI/test-execution specialist for the dcm-agent project. Your job is to run the L2
+functional integration test suite locally using Docker containers, exactly as the GitHub Actions
+workflow `.github/workflows/L2-tests.yml` does, interpret results, and guide the developer to fix
+any failures.
+
+## Responsibilities
+
+1. **Run L2 tests** inside the correct Docker containers on the developer's machine.
+2. **Prefer local images** — check `docker images` before pulling anything from GHCR.
+3. **Never pull or build images without user confirmation** when a pull is required or when
+   the local image is incompatible.
+4. **Report failures** with a triage summary: failing test, assertion text, likely root cause,
+   and a suggested fix.
+5. **Identify untested areas**: after every run, list functional areas with no L2 test coverage.
+
+---
+
+## Container Images
+
+| Image name | GHCR path | Purpose |
+|------------|-----------|---------|
+| `mockxconf` | `ghcr.io/rdkcentral/docker-device-mgt-service-test/mockxconf:latest` | Mock XConf / WebPA server |
+| `native-platform` | `ghcr.io/rdkcentral/docker-device-mgt-service-test/native-platform:latest` | Build host + test runtime |
+| `docker-rdk-ci` | `ghcr.io/rdkcentral/docker-rdk-ci:latest` | Results upload to Automatics |
+
+Container source: **https://github.com/rdkcentral/docker-device-mgt-service-test**
+
+---
+
+## Workflow
+
+### Step 1 — Check local Docker images
+
+```bash
+docker images --format "table {{.Repository}}:{{.Tag}}\t{{.ID}}\t{{.CreatedAt}}" | grep -E "mockxconf|native-platform"
+```
+
+- If **both images exist locally** → proceed directly to Step 3.
+- If **one or both are missing** → ask the user:
+
+  > "Image `<name>` is not found locally. Should I pull it from GHCR (`docker pull ...`)?
+  > If the host architecture is incompatible with the pre-built image, I can also guide you
+  > to build it from source at https://github.com/rdkcentral/docker-device-mgt-service-test
+  > (requires your approval)."
+
+  **Do not run `docker pull` or `docker build` without explicit user approval.**
+
+### Step 2 (conditional) — Authenticate, then pull or build
+
+Only after user approval. Before pulling, attempt GHCR login automatically using the
+`rdkcentral` credentials stored in `~/.netrc`:
+
+```bash
+# Extract token from ~/.netrc for ghcr.io
+NETRC_TOKEN=$(awk '/machine ghcr.io/{getline; if ($1=="password") print $2}' ~/.netrc)
+NETRC_USER=$(awk  '/machine ghcr.io/{getline; if ($1=="login")    print $2}' ~/.netrc)
+
+if [ -n "$NETRC_TOKEN" ]; then
+    echo "$NETRC_TOKEN" | docker login ghcr.io -u "$NETRC_USER" --password-stdin
+else
+    echo "No ghcr.io entry found in ~/.netrc — login skipped."
+fi
+```
+
+If `docker login` fails (exit code ≠ 0), **stop immediately** and show the user this prompt:
+
+> **GHCR login failed.** To authenticate manually:
+> 1. Create a GitHub Personal Access Token (PAT) with `read:packages` scope at
+>    https://github.com/settings/tokens
+> 2. Add it to `~/.netrc`:
+>    ```
+>    machine ghcr.io
+>    login <your-github-username>
+>    password <your-PAT>
+>    ```
+> 3. Or log in directly:
+>    ```bash
+>    echo "<your-PAT>" | docker login ghcr.io -u <your-github-username> --password-stdin
+>    ```
+> Re-run the agent once you have authenticated.
+
+Do not attempt the pull until login succeeds.
+
+```bash
+docker pull ghcr.io/rdkcentral/docker-device-mgt-service-test/mockxconf:latest
+docker pull ghcr.io/rdkcentral/docker-device-mgt-service-test/native-platform:latest
+```
+
+If the image architecture is incompatible with the host (e.g., `exec format error`), present this
+prompt to the user instead of retrying the pull:
+
+> "The pre-built image is not compatible with your host architecture.
+> To build compatible images from source, clone
+> https://github.com/rdkcentral/docker-device-mgt-service-test and run:
+> ```bash
+> docker build -t mockxconf -f Dockerfile.mockxconf .
+> docker build -t native-platform -f Dockerfile.native-platform .
+> ```
+> Shall I proceed with the build?"
+
+### Step 3 — Handle existing containers
+
+First check whether `mockxconf` or `native-platform` containers are already running:
+
+```bash
+docker ps --filter "name=mockxconf" --filter "name=native-platform" --format "table {{.Names}}\t{{.Status}}\t{{.CreatedAt}}"
+```
+
+If **either container exists** (running or stopped), **always ask the user** before removing it:
+
+> "Found existing container(s): `<names and status>`. These may be left over from a
+> previous test session. Should I stop and remove them to start a clean run?
+> (If you are debugging a previous failure, you may want to keep them.)"
+
+**Do not run `docker rm` or `docker stop` without explicit user approval.** Proceed to
+Step 4 only after confirmation.
+
+### Step 4 — Start mock XConf container
+
+```bash
+docker run -d --name mockxconf \
+  -p 50050:50050 -p 50051:50051 -p 50052:50052 -p 50053:50053 \
+  -v "$(pwd)":/mnt/L2_CONTAINER_SHARED_VOLUME \
+  mockxconf:latest   # use local tag, fall back to ghcr.io/… if pulled
+```
+
+### Step 5 — Start native-platform container
+
+```bash
+docker run -d --name native-platform \
+  --link mockxconf \
+  -v "$(pwd)":/mnt/L2_CONTAINER_SHARED_VOLUME \
+  native-platform:latest
+```
+
+### Step 6 — Build and run tests
+
+Run the build and tests as **two separate `docker exec` calls** so that a build failure
+can be detected and reported before the test runner is invoked.
+
+**6a — Build:**
+```bash
+docker exec -i native-platform /bin/bash -c \
+  "cd /mnt/L2_CONTAINER_SHARED_VOLUME/ && sh cov_build.sh"
+```
+
+If the build exits with a non-zero code:
+1. Capture the last 60 lines of compiler output.
+2. Present a **Build Failure Summary**:
+
+   ```
+   ## Build Failure Summary
+
+   **Exit code:** <N>
+
+   **First error:**
+   <file>:<line>: error: <message>
+
+   **Compiler output (last 60 lines):**
+   <output>
+
+   **Next step:** Fix the compiler error above and re-run the agent.
+   No further build or test steps will be attempted.
+   ```
+3. **Stop immediately.** Do not retry the build, do not proceed to Step 6b.
+
+**6b — Run tests** (only if 6a succeeded):
+```bash
+docker exec -i native-platform /bin/bash -c \
+  "export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu:/lib/aarch64-linux-gnu:/usr/local/lib && \
+   cd /mnt/L2_CONTAINER_SHARED_VOLUME/ && sh test/run_l2.sh && sh test/run_uploadstblogs_l2.sh"
+```
+
+### Step 7 — Collect results
+
+```bash
+docker cp native-platform:/tmp/l2_test_report /tmp/L2_TEST_RESULTS
+```
+
+### Step 8 — Analyse and report
+
+Parse JSON reports in `/tmp/L2_TEST_RESULTS/` and produce the outputs described below.
+
+---
+
+## Output Format
+
+### A. Test Run Summary
+
+| Suite | Total | Passed | Failed | Errors |
+|-------|-------|--------|--------|--------|
+| dcm-agent start/stop | N | N | N | N |
+| bootup_sequence | N | N | N | N |
+| file_existence | N | N | N | N |
+| log_upload | N | N | N | N |
+| uploadstblogs_normal | N | N | N | N |
+| uploadstblogs_error_handling | N | N | N | N |
+| uploadstblogs_retry | N | N | N | N |
+| uploadstblogs_strategies | N | N | N | N |
+| uploadstblogs_security | N | N | N | N |
+| uploadstblogs_resource_mgmt | N | N | N | N |
+| usb_logupload | N | N | N | N |
+
+### B. Failure Analysis (one entry per failed test)
+
+```
+## FAIL: <test_name>  [<suite>.json]
+
+**Assertion:**
+<exact assertion message from JSON report>
+
+**Likely cause:**
+<2–3 sentence root-cause hypothesis based on test code and source>
+
+**Suggested fix:**
+<code path, function name, or config change to investigate>
+```
+
+### C. Untested Functionality
+
+After each run, audit project components against the test suites and list areas with no L2 coverage.
+Always check these areas at minimum:
+
+| Area | Source path | L2 coverage? |
+|------|------------|-------------|
+| DCM daemon startup and initialization | `dcm.c`, `dcm_parseconf.c` | ✅ |
+| Bootup sequence | `dcmd.service` integration | ✅ |
+| DCM settings file creation | Configuration files | ✅ |
+| Log upload on reboot (true case) | `uploadstblogs/` | ✅ |
+| Log upload on reboot (false case) | `uploadstblogs/` | ✅ |
+| uploadLogsNow trigger | `uploadstblogs/src/uploadlogsnow.c` | ✅ |
+| uploadSTBLogs normal upload | `uploadstblogs/src/uploadstblogs.c` | ✅ |
+| uploadSTBLogs error handling | `uploadstblogs/src/` | ✅ |
+| uploadSTBLogs retry logic | `uploadstblogs/src/retry_logic.c` | ✅ |
+| uploadSTBLogs upload strategies | `uploadstblogs/src/strategy_*.c` | ✅ |
+| uploadSTBLogs security (mTLS/OAuth) | `uploadstblogs/src/` | ✅ |
+| uploadSTBLogs resource management | `uploadstblogs/src/` | ✅ |
+| USB log upload | `usbLogUpload/` | ✅ |
+| RBUS integration | `dcm_rbus.c` | partial |
+| Cron job parsing | `dcm_cronparse.c` | partial |
+| Scheduled job management | `dcm_schedjob.c` | partial |
+| Backup logs functionality | `backup_logs/` | ❌ |
+| Archive manager operations | `uploadstblogs/src/archive_manager.c` | partial |
+| MD5 checksum operations | `uploadstblogs/src/md5_utils.c` | partial |
+
+Update this table with actual results from each run (`✅` / `❌` / `partial`).
+
+---
+
+## Rules and Constraints
+
+- **Never** run `docker pull` or `docker build` without explicit user approval.
+- **Never** remove or stop `mockxconf` or `native-platform` containers without asking the user,
+  even if they look stale — they may be intentionally kept for debugging.
+- **Never** stop or remove any container other than `mockxconf` / `native-platform` under any
+  circumstances.
+- **Never** modify source files as part of a test run — only suggest edits.
+- **Always** attempt GHCR login from `~/.netrc` before any `docker pull`; if login fails, show
+  the credential steps prompt and stop.
+- **Always** clean up (`docker rm -f mockxconf native-platform`) at the end of a successful run,
+  unless the user asks to keep containers for debugging.
+- If `build_inside_container.sh` fails: capture output, show the Build Failure Summary, and stop.
+  **Do not retry the build.** Do not attempt any workaround or source patch.
+- If architecture incompatibility is detected, present the build-from-source prompt (see Step 2)
+  and wait for user approval before doing anything else.
+
+---
+
+## Example Invocations
+
+- "Run the L2 tests and tell me what failed."
+- "Run L2 tests using the images I already have."
+- "Which parts of dcm-agent are not covered by L2 tests?"
+- "L2 tests failed on `test_log_upload_onreboot_true_case` — what should I fix?"
+- "Run uploadSTBLogs L2 tests only."

+description: 'Expert in safely refactoring legacy C/C++ code while preventing regressions and maintaining API compatibility'
+tools: ['codebase', 'search', 'edit', 'runCommands', 'problems', 'usages']
+---
+
+# Legacy Code Refactoring Specialist
+
+You are a specialist in working with legacy embedded C/C++ code. You follow Michael Feathers' "Working Effectively with Legacy Code" principles adapted for embedded systems.
+
+## Your Mission
+
+Improve code quality, reduce technical debt, and enhance maintainability while:
+- **Zero regressions**: All existing tests must continue to pass
+- **API stability**: Maintain backward compatibility
+- **Resource constraints**: Don't increase memory footprint
+- **Production safety**: Code ships to millions of devices
+
+## Your Process
+
+### 1. Understand Before Changing
+- Read and analyze the existing code thoroughly
+- Identify all entry points and dependencies
+- Map data flow and control flow
+- Document current behavior with tests
+- Find all callers using search tools
+
+### 2. Establish Safety Net
+- Write characterization tests for existing behavior
+- Run tests before ANY changes
+- Use static analysis tools (cppcheck, valgrind)
+- Create test coverage baseline
+- Document any undefined behavior found
+
+### 3. Make Changes Incrementally
+- One small change at a time
+- Run full test suite after each change
+- Verify memory usage hasn't increased
+- Check for new static analysis warnings
+- Commit frequently with clear messages
+
+### 4. Refactoring Patterns
+
+#### Extract Function
+```c
+// BEFORE: Long function with mixed concerns
+int process_data(const char* input) {
+    // 200 lines of code doing multiple things
+    // Parsing, validation, transformation, storage
+}
+
+// AFTER: Extracted, focused functions
+static int validate_input(const char* input);
+static int parse_data(const char* input, data_t* out);
+static int store_data(const data_t* data);
+
+int process_data(const char* input) {
+    data_t data;
+    
+    if (validate_input(input) != 0) return -1;
+    if (parse_data(input, &data) != 0) return -1;
+    if (store_data(&data) != 0) return -1;
+    
+    return 0;
+}
+```
+
+#### Introduce Seam (for testing)
+```c
+// BEFORE: Hard to test due to tight coupling
+void process() {
+    FILE* f = fopen("/etc/config", "r");
+    // ... process file ...
+    fclose(f);
+}
+
+// AFTER: Dependency injection
+typedef struct {
+    FILE* (*open_file)(const char* path);
+    // ... other dependencies ...
+} dependencies_t;
+
+void process_with_deps(const dependencies_t* deps) {
+    FILE* f = deps->open_file("/etc/config");
+    // ... process file ...
+    fclose(f);
+}
+
+// Production code
+FILE* real_open(const char* path) { return fopen(path, "r"); }
+dependencies_t prod_deps = { .open_file = real_open };
+
+void process() {
+    process_with_deps(&prod_deps);
+}
+
+// Test code can inject mocks
+```
+
+#### Reduce God Object
+```c
+// BEFORE: Huge structure with everything
+typedef struct {
+    char config_path[256];
+    int config_version;
+    FILE* log_file;
+    void* data_buffer;
+    size_t buffer_size;
+    // ... 50 more fields ...
+} context_t;
+
+// AFTER: Separate concerns
+typedef struct {
+    char path[256];
+    int version;
+} config_t;
+
+typedef struct {
+    FILE* file;
+} logger_t;
+
+typedef struct {
+    void* buffer;
+    size_t size;
+} data_buffer_t;
+
+// Compose only what's needed
+typedef struct {
+    config_t* config;
+    logger_t* logger;
+    data_buffer_t* buffer;
+} context_t;
+```
+
+### 5. Memory Optimization Patterns
+
+#### Replace Heap with Stack
+```c
+// BEFORE: Unnecessary heap allocation
+char* format_message(const char* fmt, ...) {
+    char* buf = malloc(256);
+    // ... format into buf ...
+    return buf;  // Caller must free
+}
+
+// AFTER: Use stack (if size is known and reasonable)
+#define MSG_MAX_SIZE 256
+
+int format_message(char* buf, size_t size, const char* fmt, ...) {
+    // ... format into buf ...
+    return strlen(buf);
+}
+
+// Caller:
+char msg[MSG_MAX_SIZE];
+format_message(msg, sizeof(msg), "Error: %d", code);
+```
+
+#### Memory Pool for Frequent Allocations
+```c
+// BEFORE: Frequent malloc/free causing fragmentation
+for (int i = 0; i < 1000; i++) {
+    event_t* e = malloc(sizeof(event_t));
+    process_event(e);
+    free(e);
+}
+
+// AFTER: Pre-allocated pool
+#define EVENT_POOL_SIZE 10
+
+typedef struct {
+    event_t events[EVENT_POOL_SIZE];
+    bool used[EVENT_POOL_SIZE];
+} event_pool_t;
+
+event_t* event_pool_acquire(event_pool_t* pool);
+void event_pool_release(event_pool_t* pool, event_t* event);
+
+// Usage
+event_pool_t pool = {0};
+for (int i = 0; i < 1000; i++) {
+    event_t* e = event_pool_acquire(&pool);
+    process_event(e);
+    event_pool_release(&pool, e);
+}
+```
+
+## Regression Prevention
+
+### Before Any Refactoring
+1. Ensure all existing tests pass
+2. Run valgrind (no leaks in current code)
+3. Measure memory footprint baseline
+4. Document current behavior
+
+### During Refactoring
+1. Make one logical change at a time
+2. Run tests after EVERY change
+3. Use git to create checkpoint commits
+4. Monitor memory usage
+
+### After Refactoring
+1. All tests still pass
+2. No new memory leaks (valgrind)
+3. Memory footprint same or better
+4. No new compiler warnings
+5. Static analysis clean
+6. Code review by human
+
+## Communication
+
+### When Proposing Changes
+- Explain the problem being solved
+- Show before/after comparison
+- Highlight safety measures
+- Document any risks
+- Estimate memory impact
+
+### When Blocked
+- Explain what's preventing progress
+- Suggest alternatives
+- Ask for clarification on requirements
+- Note any missing tests
+
+### Code Review Focus
+- Point out missing error handling
+- Identify memory leak risks
+- Note API compatibility concerns
+- Suggest additional test cases
+- Highlight complexity that could be simplified
+
+## Emergency Procedures
+
+If tests start failing:
+1. **STOP** immediately
+2. Review the last change
+3. Use git diff to see what changed
+4. Revert if cause isn't obvious
+5. Fix the issue before continuing
+
+If memory leaks detected:
+1. **STOP** the refactoring
+2. Run valgrind to identify leak
+3. Fix the leak
+4. Verify fix with valgrind
+5. Resume refactoring
+
+If API breaks:
+1. **REVERT** the breaking change
+2. Find alternative approach
+3. Use wrapper functions if needed
+4. Maintain old API alongside new
+
+## Success Criteria
+
+You've succeeded when:
+- All tests pass
+- No memory leaks (valgrind clean)
+- Code is more maintainable
+- No API breaks
+- Memory footprint same or improved
+- Complexity metrics improved

+## Project Overview
+- Consists mainly of shell scripts and C code that will run during initialization or house keeping of embedded systems.
+- The software will be deployed on a variety of embedded systems.
+- These systems have limited memory (ranging from a few KBs to a few MBs).
+- CPU resources are constrained, often with low clock speeds.
+- Real-time performance may be required in some cases.
+- The environment may lack standard OS features like file systems or dynamic memory allocation.
+- Cross-compilation will be used for building the software.
+- Multiple architectures and compiler toolchains must be supported.
+- Software must be platform-neutral and portable.
+- Software should be easy to maintain, extendable, and should follow modular design principles.
+- Use fixed-point arithmetic where possible instead of floating-point.
+- Ensure thread safety, thread pooling if applicable.
+- Avoid using dynamic memory allocation to best extent possible. Use memory pools if applicable.
+- Provide clear error handling and reporting mechanisms.
+
+## Folder Structure
+- All source files will be placed in the `src/` directory.
+- All header files will be placed in the `include/` directory.
+- All unit tests will be placed in the `src/test/` directory.
+- All documentation will be placed in the `docs/` directory.
+
+## Available opensource components and libraries that can be used 
+- List of opensource libraries that could used is available in - https://github.com/rdkcentral/meta-oss-reference-release/tree/main#components-details-in-packagegroup-oss-layer
+
+## Security Considerations
+- Follow secure coding practices to prevent common vulnerabilities.
+- Validate all inputs rigorously.
+- Manage memory safely to avoid leaks and overflows.
+- Implement authentication and authorization where applicable.
+- Encrypt sensitive data in transit and at rest.
+- Keep third-party dependencies up to date and minimal.
+- Conduct regular security reviews and testing.
+
+## Documentation Guidelines
+- Use Markdown format for easy readability.
+- Dependencies and versioning should be clearly documented in `docs/DEPENDENCIES.md`.
+
+## Unit Testing
+- Unit tests will be placed in the src/test directory.
+- Use Google Test and Google Mock frameworks.
+- Aim for test coverage above 80%.
+- Include tests for edge cases and error conditions.
+- Automate tests using a CI/CD pipeline and github workflows.
+- Unit tests should be performed on containerized environment using docker image - https://github.com/rdkcentral/docker-rdk-ci/pkgs/container/docker-rdk-ci
+
+## Task Specific Instructions/Prompts
+- Task specific instructions could be added in `.github/instructions/*task-features*.md` file.
+
+
+## Folder Structure
+
+- All source files will be linted using astyle with the configuration file located at `.astyle.rc`.
+- Use autotools for build configuration and Makefiles for compilation.
+- Use `gcc` as the primary compiler, ensuring compatibility with `clang` where possible.

+# Build System Standards (Autotools)
+
+## Autotools Best Practices
+
+### configure.ac
+- Check for required headers and functions
+- Provide clear error messages for missing dependencies
+- Support cross-compilation
+- Allow feature toggles
+
+```autoconf
+# GOOD: Check for required features
+AC_CHECK_HEADERS([pthread.h], [],
+    [AC_MSG_ERROR([pthread.h is required])])
+
+AC_CHECK_LIB([pthread], [pthread_create], [],
+    [AC_MSG_ERROR([pthread library is required])])
+
+# GOOD: Optional features with clear naming
+AC_ARG_ENABLE([gtest],
+    AS_HELP_STRING([--enable-gtest], [Enable Google Test support]),
+    [enable_gtest=$enableval],
+    [enable_gtest=no])
+
+AM_CONDITIONAL([WITH_GTEST_SUPPORT], [test "x$enable_gtest" = "xyes"])
+```
+
+### Makefile.am
+- Use non-recursive makefiles when possible
+- Minimize intermediate libraries
+- Support parallel builds
+- Link only what's needed
+
+```makefile
+# GOOD: Minimal linking
+bin_PROGRAMS = dcmd uploadstblogs uploadlogsnow
+
+dcmd_SOURCES = dcm.c dcm_utils.c dcm_parseconf.c dcm_cronparse.c dcm_schedjob.c dcm_rbus.c

+uploadstblogs_LDADD = \
+    $(top_builddir)/uploadstblogs/src/libuploadstblogs.la \
+    -lcurl -lssl -lcrypto -lrbus
+
+# GOOD: Conditional compilation
+if WITH_GTEST_SUPPORT
+SUBDIRS += src/unittest
+endif
+```
+
+## Cross-Compilation Support
+
+### Platform Detection
+```autoconf
+# Support different target platforms
+case "$host" in
+    *-linux*)
+        AC_DEFINE([PLATFORM_LINUX], [1], [Linux platform])
+        ;;
+    *-arm*)
+        AC_DEFINE([PLATFORM_ARM], [1], [ARM platform])
+        ;;
+esac
+```
+
+### Compiler Flags
+```makefile
+# Platform-specific optimizations
+if TARGET_ARM
+AM_CFLAGS += -march=armv7-a -mfpu=neon
+endif
+
+# Debug vs Release
+if DEBUG_BUILD
+AM_CFLAGS += -g -O0 -DDEBUG
+else
+AM_CFLAGS += -O2 -DNDEBUG
+endif
+```
+
+## Dependency Management
+
+### Package Config
+```autoconf
+# Use pkg-config for external dependencies
+PKG_CHECK_MODULES([DBUS], [dbus-1 >= 1.6])
+AC_SUBST([DBUS_CFLAGS])
+AC_SUBST([DBUS_LIBS])
+```
+
+### Header Organization
+```makefile
+# Include paths
+AM_CPPFLAGS = -I$(top_srcdir)/include \
+              -I$(top_srcdir)/uploadstblogs/include \
+              -I$(top_srcdir)/backup_logs/include \

+              $(DBUS_CFLAGS)
+```
+
+## Build Performance
+
+### Parallel Builds
+- Support `make -j`
+- Avoid circular dependencies
+- Use order-only prerequisites when appropriate
+
+### Incremental Builds
+- Proper dependency tracking
+- Don't force full rebuilds unless necessary

+
+## Memory Management
+
+### Allocation Rules
+- **Prefer stack allocation** for fixed-size, short-lived data
+- **Use malloc/free** only when necessary; always pair them
+- **Check all allocations**: Never assume malloc succeeds
+- **Free in reverse order** of allocation to reduce fragmentation
+- **Use memory pools** for frequent same-size allocations
+- **Zero memory after free** to catch use-after-free bugs in debug builds
+
+```c
+// GOOD: Stack allocation for fixed-size data
+char buffer[256];
+
+// GOOD: Checked heap allocation with cleanup
+char* data = malloc(size);
+if (!data) {
+    log_error("Failed to allocate %zu bytes", size);
+    return ERR_NO_MEMORY;
+}
+// ... use data ...
+free(data);
+data = NULL;  // Prevent double-free
+
+// BAD: Unchecked allocation
+char* data = malloc(size);
+strcpy(data, input);  // Crash if malloc failed
+```
+
+### Memory Leak Prevention
+- Every function that allocates must document ownership transfer
+- Use goto for single exit point in complex error handling
+- Implement cleanup functions for complex structures
+- Use valgrind regularly during development
+
+```c
+// GOOD: Single exit point with cleanup
+int process_data(const char* input) {
+    int ret = 0;
+    char* buffer = NULL;
+    FILE* file = NULL;
+    
+    buffer = malloc(BUFFER_SIZE);
+    if (!buffer) {
+        ret = ERR_NO_MEMORY;
+        goto cleanup;
+    }
+    
+    file = fopen(input, "r");
+    if (!file) {
+        ret = ERR_FILE_OPEN;
+        goto cleanup;
+    }
+    
+    // ... processing ...
+    
+cleanup:
+    free(buffer);
+    if (file) fclose(file);
+    return ret;
+}
+```
+
+## Resource Constraints
+
+### Code Size Optimization
+- Avoid inline functions unless proven beneficial
+- Share common code paths
+- Use function pointers for conditional logic in tables
+- Strip debug symbols in release builds
+
+### CPU Optimization
+- Minimize system calls
+- Cache frequently accessed data
+- Use efficient algorithms (prefer O(n) over O(n²))
+- Avoid floating point on devices without FPU
+- Profile before optimizing (don't guess)
+
+### Memory Optimization
+- Use bitfields for boolean flags
+- Pack structures to minimize padding
+- Use const for read-only data (goes in .rodata)
+- Prefer static buffers with maximum sizes when bounds are known
+- Implement object pools for frequently created/destroyed objects
+
+```c
+// GOOD: Packed structure
+typedef struct __attribute__((packed)) {
+    uint8_t flags;
+    uint16_t id;
+    uint32_t timestamp;
+    char name[32];
+} telemetry_event_t;
+
+// GOOD: Const data in .rodata
+static const char* const ERROR_MESSAGES[] = {
+    "Success",
+    "Out of memory",
+    "Invalid parameter",
+    // ...
+};
+```
+
+## Platform Independence
+
+### Never Assume
+- Pointer size (use uintptr_t for pointer arithmetic)
+- Byte order (use htonl/ntohl for network data)
+- Structure packing (use __attribute__((packed)) or #pragma pack)
+- Integer sizes (use int32_t, uint64_t from stdint.h)
+- Boolean type (use stdbool.h)
+
+```c
+// GOOD: Platform-independent types
+#include <stdint.h>
+#include <stdbool.h>
+
+typedef struct {
+    uint32_t id;           // Always 32 bits
+    uint64_t timestamp;    // Always 64 bits
+    bool enabled;          // Standard boolean
+} config_t;
+
+// GOOD: Endianness handling
+uint32_t network_value = htonl(host_value);
+
+// BAD: Assumptions
+int id;  // Size varies by platform
+long timestamp;  // 32 or 64 bits depending on platform
+```
+
+### Abstraction Layers
+- Use platform abstraction for OS-specific code
+- Isolate hardware dependencies
+- Use configure.ac to detect platform capabilities
+
+## Error Handling
+
+### Return Value Convention
+- Return 0 for success, negative for errors
+- Use errno for system call failures
+- Define error codes in header files
+- Never ignore return values
+
+```c
+// GOOD: Consistent error handling
+typedef enum {
+    T2ERROR_SUCCESS = 0,
+    T2ERROR_FAILURE = -1,
+    T2ERROR_INVALID_PARAM = -2,
+    T2ERROR_NO_MEMORY = -3,
+    T2ERROR_TIMEOUT = -4
+} T2ERROR;
+
+T2ERROR init_telemetry() {
+    if (!validate_config()) {
+        return T2ERROR_INVALID_PARAM;
+    }
+    
+    if (allocate_resources() != 0) {
+        return T2ERROR_NO_MEMORY;
+    }
+    
+    return T2ERROR_SUCCESS;
+}
+```
+
+### Logging
+- Use severity levels appropriately
+- Log errors with context (function, line, errno)
+- Avoid logging in hot paths
+- Make logging configurable at runtime
+- Never log sensitive data
+
+```c
+// GOOD: Contextual error logging
+if (ret != 0) {
+    T2Error("%s:%d Failed to initialize: %s (errno=%d)", 
+            __FUNCTION__, __LINE__, strerror(errno), errno);
+    return T2ERROR_FAILURE;
+}
+```
+
+## Thread Safety and Concurrency
+
+### Critical Principles
+
+- **Minimize synchronization overhead**: Use lightweight primitives
+- **Prevent deadlocks**: Establish lock ordering, use timeouts
+- **Avoid memory fragmentation**: Configure thread stack sizes appropriately
+- **Reduce contention**: Design for lock-free patterns where possible
+- **Document thread safety**: Mark functions as thread-safe or not
+
+### Thread Creation with Minimal Memory
+
+Always create threads with attributes that specify required memory:
+
+```c
+// GOOD: Thread with minimal stack size
+#include <pthread.h>
+
+#define THREAD_STACK_SIZE (64 * 1024)  // 64KB instead of default (often 8MB)
+
+pthread_t thread;
+pthread_attr_t attr;
+
+// Initialize attributes
+pthread_attr_init(&attr);
+
+// Set minimal stack size (reduces memory fragmentation)
+pthread_attr_setstacksize(&attr, THREAD_STACK_SIZE);
+
+// Detached threads free resources immediately when done
+pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED);
+
+// Create thread
+int ret = pthread_create(&thread, &attr, thread_function, arg);
+if (ret != 0) {
+    T2Error("Failed to create thread: %s", strerror(ret));
+    pthread_attr_destroy(&attr);
+    return T2ERROR_FAILURE;
+}
+
+// Clean up attributes
+pthread_attr_destroy(&attr);
+
+// BAD: Default thread (wastes memory)
+pthread_create(&thread, NULL, thread_function, arg);  // Uses 8MB stack!
+```
+
+### Lightweight Synchronization
+
+Prefer lightweight synchronization primitives to avoid deadlocks and overhead:
+
+```c
+// GOOD: Simple mutex with minimal overhead
+typedef struct {
+    pthread_mutex_t lock;
+    int counter;
+} thread_safe_counter_t;
+
+int init_counter(thread_safe_counter_t* c) {
+    // Use default attributes (lightest weight)
+    pthread_mutex_init(&c->lock, NULL);
+    c->counter = 0;
+    return 0;
+}
+
+void increment_counter(thread_safe_counter_t* c) {
+    pthread_mutex_lock(&c->lock);
+    c->counter++;
+    pthread_mutex_unlock(&c->lock);
+}
+
+void cleanup_counter(thread_safe_counter_t* c) {
+    pthread_mutex_destroy(&c->lock);
+}
+
+// GOOD: Use atomic operations when possible (no locks needed)
+#include <stdatomic.h>
+
+typedef struct {
+    atomic_int counter;  // Lock-free!
+} lockfree_counter_t;
+
+void increment_lockfree(lockfree_counter_t* c) {
+    atomic_fetch_add(&c->counter, 1);  // No mutex overhead
+}
+```
+
+### Deadlock Prevention
+
+Follow strict rules to prevent deadlocks:
+
+```c
+// GOOD: Consistent lock ordering
+typedef struct {
+    pthread_mutex_t lock_a;
+    pthread_mutex_t lock_b;
+    // ... data ...
+} resource_t;
+
+// RULE: Always acquire locks in alphabetical order (a, then b)
+void multi_lock_operation(resource_t* r) {
+    pthread_mutex_lock(&r->lock_a);   // First: lock_a
+    pthread_mutex_lock(&r->lock_b);   // Second: lock_b
+    
+    // ... critical section ...
+    
+    pthread_mutex_unlock(&r->lock_b);  // Release in reverse order
+    pthread_mutex_unlock(&r->lock_a);
+}
+
+// GOOD: Use trylock with timeout to avoid indefinite blocking
+#include <time.h>
+
+int safe_lock_with_timeout(pthread_mutex_t* lock, int timeout_ms) {
+    struct timespec ts;
+    clock_gettime(CLOCK_REALTIME, &ts);
+    ts.tv_sec += timeout_ms / 1000;
+    ts.tv_nsec += (timeout_ms % 1000) * 1000000;
+    
+    int ret = pthread_mutex_timedlock(lock, &ts);
+    if (ret == ETIMEDOUT) {
+        T2Error("Lock timeout - potential deadlock detected");
+        return -1;
+    }
+    return ret;
+}
+
+// BAD: Different lock order in different functions (DEADLOCK RISK!)
+void bad_function_1(resource_t* r) {
+    pthread_mutex_lock(&r->lock_a);
+    pthread_mutex_lock(&r->lock_b);  // Order: a, b
+    // ...
+}
+
+void bad_function_2(resource_t* r) {
+    pthread_mutex_lock(&r->lock_b);
+    pthread_mutex_lock(&r->lock_a);  // Order: b, a - DEADLOCK!
+    // ...
+}
+```
+
+### Avoid Heavy Synchronization
+
+Heavy synchronization causes performance issues and fragmentation:
+
+```c
+// BAD: Reader-writer lock for simple counter (overkill)
+pthread_rwlock_t heavy_lock;
+int counter;
+
+void heavy_increment() {
+    pthread_rwlock_wrlock(&heavy_lock);  // Too heavy!
+    counter++;
+    pthread_rwlock_unlock(&heavy_lock);
+}
+
+// GOOD: Use appropriate synchronization level
+atomic_int light_counter;  // Lock-free for simple operations
+
+void light_increment() {
+    atomic_fetch_add(&light_counter, 1);  // No lock overhead
+}
+
+// BAD: Fine-grained locking everywhere (lock thrashing)
+typedef struct {
+    pthread_mutex_t lock;
+    int value;
+} each_field_locked_t;  // Don't do this!
+
+// GOOD: Coarse-grained locking for related data
+typedef struct {
+    pthread_mutex_t lock;
+    int value_a;
+    int value_b;
+    int value_c;  // All protected by one lock
+} properly_locked_t;
+```
+
+### Lock-Free Patterns
+
+Use lock-free patterns to avoid synchronization overhead:
+
+```c
+// GOOD: Lock-free flag
+#include <stdatomic.h>
+
+typedef struct {
+    atomic_bool shutdown_requested;
+} thread_control_t;
+
+void request_shutdown(thread_control_t* ctrl) {
+    atomic_store(&ctrl->shutdown_requested, true);
+}
+
+bool should_shutdown(thread_control_t* ctrl) {
+    return atomic_load(&ctrl->shutdown_requested);
+}
+
+// GOOD: Lock-free queue for single producer, single consumer
+typedef struct {
+    atomic_int read_index;
+    atomic_int write_index;
+    void* buffer[256];
+} spsc_queue_t;
+
+bool spsc_enqueue(spsc_queue_t* q, void* item) {
+    int write = atomic_load(&q->write_index);
+    int next_write = (write + 1) % 256;
+    
+    if (next_write == atomic_load(&q->read_index)) {
+        return false;  // Queue full
+    }
+    
+    q->buffer[write] = item;
+    atomic_store(&q->write_index, next_write);
+    return true;
+}
+```
+
+### Minimize Critical Sections
+
+Keep locked sections as short as possible:
+
+```c
+// BAD: Long critical section
+void bad_process(data_t* shared) {
+    pthread_mutex_lock(&shared->lock);
+    
+    // Heavy computation while holding lock (BAD!)
+    for (int i = 0; i < 1000000; i++) {
+        compute_something();
+    }
+    
+    shared->value = result;
+    pthread_mutex_unlock(&shared->lock);
+}
+
+// GOOD: Minimal critical section
+void good_process(data_t* shared) {
+    // Do heavy computation WITHOUT lock
+    int result = 0;
+    for (int i = 0; i < 1000000; i++) {
+        result += compute_something();
+    }
+    
+    // Lock only for the update
+    pthread_mutex_lock(&shared->lock);
+    shared->value = result;
+    pthread_mutex_unlock(&shared->lock);
+}
+```
+
+### Thread-Safe Initialization
+
+Use pthread_once for thread-safe initialization:
+
+```c
+// GOOD: Thread-safe singleton initialization
+static pthread_once_t init_once = PTHREAD_ONCE_INIT;
+static config_t* global_config = NULL;
+
+static void init_config_once(void) {
+    global_config = malloc(sizeof(config_t));
+    // ... initialize config ...
+}
+
+config_t* get_config(void) {
+    pthread_once(&init_once, init_config_once);
+    return global_config;
+}
+
+// BAD: Double-checked locking (broken in C without memory barriers)
+static pthread_mutex_t init_lock;
+static config_t* config = NULL;
+
+config_t* bad_get_config(void) {
+    if (config == NULL) {  // First check (no lock)
+        pthread_mutex_lock(&init_lock);
+        if (config == NULL) {  // Second check
+            config = malloc(sizeof(config_t));  // Race condition!
+        }
+        pthread_mutex_unlock(&init_lock);
+    }
+    return config;
+}
+```
+
+### Thread Safety Documentation
+
+Always document thread safety expectations:
+
+```c
+// GOOD: Clear thread safety documentation
+
+/**
+ * Process telemetry event
+ * @param event Event to process
+ * @return 0 on success, negative on error
+ * 
+ * Thread Safety: This function is thread-safe and may be called
+ *                from multiple threads concurrently.
+ */
+int process_event(const event_t* event) {
+    // Uses internal locking
+}
+
+/**
+ * Initialize event processor
+ * @return 0 on success, negative on error
+ * 
+ * Thread Safety: NOT thread-safe. Must be called once during
+ *                initialization before any worker threads start.
+ */
+int init_event_processor(void) {
+    // No locking - initialization only
+}
+
+/**
+ * Get current statistics
+ * @param stats Output buffer for statistics
+ * 
+ * Thread Safety: Caller must hold stats_lock before calling.
+ *                Use get_stats_safe() for automatic locking.
+ */
+void get_stats_unlocked(stats_t* stats) {
+    // Assumes caller holds lock
+}
+```
+
+### Memory Fragmentation Prevention
+
+Configure thread pools to prevent fragmentation:
+
+```c
+// GOOD: Thread pool with pre-allocated threads
+#define THREAD_POOL_SIZE 4
+#define WORK_QUEUE_SIZE 256
+
+typedef struct {
+    pthread_t threads[THREAD_POOL_SIZE];
+    pthread_attr_t thread_attr;
+    // ... work queue ...
+} thread_pool_t;
+
+int init_thread_pool(thread_pool_t* pool) {
+    // Configure thread attributes once
+    pthread_attr_init(&pool->thread_attr);
+    pthread_attr_setstacksize(&pool->thread_attr, THREAD_STACK_SIZE);
+    pthread_attr_setdetachstate(&pool->thread_attr, PTHREAD_CREATE_JOINABLE);
+    
+    // Create fixed number of threads (no dynamic allocation)
+    for (int i = 0; i < THREAD_POOL_SIZE; i++) {
+        int ret = pthread_create(&pool->threads[i], &pool->thread_attr,
+                                 worker_thread, pool);
+        if (ret != 0) {
+            // Cleanup already created threads
+            cleanup_partial_pool(pool, i);
+            return -1;
+        }
+    }
+    
+    return 0;
+}
+
+// BAD: Creating threads dynamically (causes fragmentation)
+void bad_handle_request(request_t* req) {
+    pthread_t thread;
+    pthread_create(&thread, NULL, handle_one_request, req);
+    pthread_detach(thread);  // New thread for each request!
+}
+```
+
+### Testing Thread Safety
+
+```c
+// GOOD: Test for race conditions
+#include <gtest/gtest.h>
+
+TEST(ThreadSafety, ConcurrentIncrement) {
+    thread_safe_counter_t counter = {0};
+    init_counter(&counter);
+    
+    const int NUM_THREADS = 10;
+    const int INCREMENTS_PER_THREAD = 1000;
+    pthread_t threads[NUM_THREADS];
+    
+    // Create multiple threads
+    for (int i = 0; i < NUM_THREADS; i++) {
+        pthread_create(&threads[i], NULL, 
+                      increment_n_times, &counter);
+    }
+    
+    // Wait for all threads
+    for (int i = 0; i < NUM_THREADS; i++) {
+        pthread_join(threads[i], NULL);
+    }
+    
+    // Verify no race conditions
+    EXPECT_EQ(counter.counter, NUM_THREADS * INCREMENTS_PER_THREAD);
+    
+    cleanup_counter(&counter);
+}
+```
+
+### Static Analysis for Concurrency
+
+```bash
+# Use thread sanitizer to detect race conditions
+gcc -g -fsanitize=thread source.c -o program
+./program
+
+# Use helgrind (valgrind) to detect synchronization issues
+valgrind --tool=helgrind ./program
+
+# Check for deadlocks
+valgrind --tool=helgrind --track-lockorders=yes ./program
+```
+
+## Code Style
+
+### Naming Conventions
+- Functions: `snake_case` (e.g., `init_telemetry`)
+- Types: `snake_case_t` (e.g., `telemetry_event_t`)
+- Macros/Constants: `UPPER_SNAKE_CASE` (e.g., `MAX_BUFFER_SIZE`)
+- Global variables: `g_` prefix (avoid when possible)
+- Static variables: `s_` prefix
+
+### File Organization
+- One .c file per module
+- Corresponding .h file for public interface
+- Internal functions marked static
+- Header guards in all .h files
+
+```c
+// GOOD: header guard
+#ifndef TELEMETRY_INTERNAL_H
+#define TELEMETRY_INTERNAL_H
+
+// ... declarations ...
+
+#endif /* TELEMETRY_INTERNAL_H */
+```
+
+## Testing Requirements
+
+### Unit Tests
+- Test all public functions
+- Test error paths and edge cases
+- Use mocks for external dependencies
+- Verify resource cleanup (no leaks)
+- Run tests under valgrind
+
+### Memory Testing
+```bash
+# Run with memory checking
+valgrind --leak-check=full --show-leak-kinds=all \
+         --track-origins=yes ./test_binary
+
+# Static analysis
+cppcheck --enable=all --inconclusive source/
+```
+
+## Anti-Patterns to Avoid
+
+```c
+// BAD: Magic numbers
+if (size > 1024) { ... }
+
+// GOOD: Named constants
+#define MAX_PACKET_SIZE 1024
+if (size > MAX_PACKET_SIZE) { ... }
+
+// BAD: Unchecked allocation
+char* buf = malloc(size);
+strcpy(buf, input);
+
+// GOOD: Checked with cleanup
+char* buf = malloc(size);
+if (!buf) return ERR_NO_MEMORY;
+strncpy(buf, input, size - 1);
+buf[size - 1] = '\0';
+
+// BAD: Memory leak in error path
+FILE* f = fopen(path, "r");
+if (condition) return -1;  // Leaked f
+fclose(f);
+
+// GOOD: Cleanup on all paths
+FILE* f = fopen(path, "r");
+if (!f) return -1;
+if (condition) {
+    fclose(f);
+    return -1;
+}
+fclose(f);
+return 0;
+```

+# C++ Testing Standards (Google Test)
+
+## Test Framework
+
+Use Google Test (gtest) and Google Mock (gmock) for all C++ test code.
+
+## Test Organization
+
+### File Structure
+- One test file per source file: `foo.c` → `test/FooTest.cpp`
+- Test fixtures for complex setups
+- Mocks in separate files when reusable
+
+```cpp
+// GOOD: Test file structure
+// filepath: unittest/dcm_utils_gtest.cpp
+
+extern "C" {
+#include "dcm_utils.h"
+#include "dcm_types.h"
+}
+
+#include <gtest/gtest.h>
+#include <gmock/gmock.h>
+
+class DcmUtilsTest : public ::testing::Test {
+protected:
+    void SetUp() override {
+        // Initialize test resources
+    }
+    
+    void TearDown() override {
+        // Clean up test resources
+    }
+};
+
+TEST_F(DcmUtilsTest, ConfigFileReadWriteRoundTrip) {
+    // Test configuration file parsing
+    const char* config = "/tmp/test.conf";
+    // verify read back value matches written value
+    ASSERT_EQ(readConfigValue(config, "key"), "value");
+}
+```
+
+## Testing Patterns
+
+### Test C Code from C++
+- Wrap C headers in `extern "C"` blocks
+- Use RAII in tests for automatic cleanup
+- Mock C functions using gmock when needed
+
+```cpp
+extern "C" {
+#include "dcm_parseconf.h"
+#include "dcm_rbus.h"
+}
+
+#include <gtest/gtest.h>
+
+class DcmParseConfTest : public ::testing::Test {
+protected:
+    void SetUp() override {
+        // Initialize handler stubs
+    }
+    
+    void TearDown() override {
+        // Clean up
+    }
+};
+
+TEST_F(DcmParseConfTest, ParseConfigReturnsExpected) {
+    DCMDHandle handle = {};
+    // Test configuration parsing
+    int result = dcmParseConfig(&handle, "/etc/dcmresponse.txt");
+    // verify handler returns success and populates configuration
+    ASSERT_EQ(result, 0);
+}
+```
+
+### Memory Leak Testing
+- All tests must pass valgrind
+- Use RAII wrappers for C resources
+- Verify cleanup in TearDown
+
+```cpp
+// GOOD: RAII wrapper for C resource
+class FileHandle {
+    FILE* file_;
+public:
+    explicit FileHandle(const char* path, const char* mode)
+        : file_(fopen(path, mode)) {}
+    
+    ~FileHandle() {
+        if (file_) fclose(file_);
+    }
+    
+    FILE* get() const { return file_; }
+    bool valid() const { return file_ != nullptr; }
+};
+
+TEST(FileTest, ReadConfig) {
+    FileHandle file("/tmp/config.json", "r");
+    ASSERT_TRUE(file.valid());
+    // file automatically closed when test exits
+}
+```
+
+### Mocking External Dependencies
+
+```cpp
+// GOOD: Mock for handler dependencies
+class MockIniFile {
+public:
+    MOCK_METHOD(std::string, get, (const std::string& key));
+    MOCK_METHOD(bool, set, (const std::string& key, const std::string& value));
+};
+
+TEST(HandlerTest, GetParamUsesIniFile) {
+    MockIniFile mock;
+    
+    EXPECT_CALL(mock, get("Device.DeviceInfo.Manufacturer"))
+        .WillOnce(testing::Return("TestVendor"));
+    
+    std::string result = mock.get("Device.DeviceInfo.Manufacturer");
+    EXPECT_EQ("TestVendor", result);
+}
+```
+
+## Test Quality Standards
+
+### Coverage Requirements
+- All public functions must have tests
+- Test both success and failure paths
+- Test boundary conditions
+- Test error handling
+
+### Test Naming
+```cpp
+// Pattern: TEST(ComponentName, BehaviorBeingTested)
+
+TEST(Vector, CreateReturnsNonNull) { ... }
+TEST(Vector, DestroyHandlesNull) { ... }
+TEST(Vector, PushIncrementsSize) { ... }
+TEST(Utils, ParseConfigInvalidJson) { ... }
+```
+
+### Assertions
+- Use `ASSERT_*` when test can't continue after failure
+- Use `EXPECT_*` when subsequent checks are still valuable
+- Provide helpful failure messages
+
+```cpp
+// GOOD: Informative assertions
+ASSERT_NE(nullptr, ptr) << "Failed to allocate " << size << " bytes";
+EXPECT_EQ(expected, actual) << "Mismatch at index " << i;
+EXPECT_TRUE(condition) << "Context: " << debug_info;
+```
+
+## Running Tests
+
+### Build Tests
+```bash
+./configure --enable-gtest
+make check
+```
+
+### Memory Checking
+```bash
+valgrind --leak-check=full --show-leak-kinds=all \
+         ./unittest/dcm_gtest
+
+valgrind --leak-check=full --show-leak-kinds=all \
+         ./uploadstblogs/unittest/uploadstblogs_gtest
+```
+
+### Test Output
+- Use `GTEST_OUTPUT=xml:results.xml` for CI integration
+- Check return code: 0 = all passed

+## HLD Generation Guidelines
+
+- **Project Goal:** Migrate existing scripts to C code.
+- **Target Platforms:** Multiple embedded platforms with low memory and low CPU resources.
+- **Constraints:** Code must be efficient, lightweight, and platform-neutral to ensure portability across different embedded systems.
+
+## Migration Strategy
+1. **Requirements Gathering**
+    - For scripts selected in context, create a Markdown (`.md`) file documenting:
+        - Functional requirements
+        - Inputs/outputs
+        - Dependencies
+        - Constraints (timing, memory, etc.)
+        - Edge cases and error handling
+
+2. **High Level Design (HLD)**
+    - For each script, create a separate HLD `.md` file including:
+        - Architecture overview
+        - Module/component breakdown
+        - Data flow diagrams or descriptions
+        - Key algorithms and data structures
+        - Interfaces and integration points
+
+3. **Flowchart Creation**
+   - Develop flowcharts to visually represent the script's logic and workflow.
+   - Use `mermaid` syntax for creating flowcharts.
+   - For environments that may have issues with complex Mermaid diagrams, include a simplified text-based flowchart alternative.
+   - For scripts having related functionality, create combined or linked flowcharts to show interactions.
+   - Use standard flowchart symbols for processes, decisions, inputs/outputs, and connectors.
+   - Ensure flowcharts are clear, concise, and accurately reflect the script's functionality.
+   - Include annotations or notes for complex logic or important details.
+   - Store flowcharts in a dedicated directory within the project for easy reference.
+
+4. **Sequence Diagrams**
+   - Create sequence diagrams to illustrate interactions between components or modules.
+   - Use `mermaid` syntax for creating sequence diagrams.
+   - For environments that may have issues with complex Mermaid diagrams, include a simplified text-based sequence diagram alternative.
+   - Ensure diagrams clearly show the order of operations and interactions.
+   - Include annotations for clarity where necessary.
+   
+5. **LLD Preparation**
+   - Prepare a Low-Level Design (LLD) document outlining:
+       - Detailed design specifications
+       - Data structures and algorithms
+       - Pseudocode or code snippets
+       - Interface definitions
+       - Error handling and edge cases
+
+5. **Fine tuning**
+   - Do not create implementation roadmap markdown files.
+   - Do not suggest timelines or planning details for execution.

+# Shell Script Standards for Embedded Systems
+
+## Platform Independence
+
+### Use POSIX Shell
+- Use `#!/bin/sh` not `#!/bin/bash`
+- Avoid bashisms (use shellcheck to verify)
+- Test on busybox ash (common in embedded)
+
+```bash
+#!/bin/sh
+# GOOD: POSIX compliant
+
+# BAD: Bash-specific
+if [[ $var == "value" ]]; then  # Use [ ] instead
+    array=(1 2 3)  # Arrays not in POSIX
+fi
+
+# GOOD: POSIX compliant
+if [ "$var" = "value" ]; then
+    set -- 1 2 3  # Use positional parameters
+fi
+```
+
+## Resource Awareness
+
+### Minimize Process Spawning
+- Use shell builtins when possible
+- Avoid pipes when not necessary
+- Batch operations to reduce forks
+
+```bash
+# BAD: Multiple processes
+cat file | grep pattern | wc -l
+
+# GOOD: Fewer processes
+grep -c pattern file
+
+# BAD: Loop with external commands
+for file in *.txt; do
+    cat "$file" >> output
+done
+
+# GOOD: Single cat invocation
+cat *.txt > output
+```
+
+### Memory Usage
+- Avoid reading entire files into variables
+- Process streams line by line
+- Clean up temporary files
+
+```bash
+# BAD: Loads entire file into memory
+content=$(cat large_file.log)
+echo "$content" | grep ERROR
+
+# GOOD: Stream processing
+grep ERROR large_file.log
+
+# GOOD: Line-by-line processing
+while IFS= read -r line; do
+    process_line "$line"
+done < large_file.log
+```
+
+## Error Handling
+
+### Always Check Exit Codes
+```bash
+# GOOD: Check critical operations
+if ! mkdir -p /tmp/telemetry; then
+    logger -t telemetry "ERROR: Failed to create directory"
+    exit 1
+fi
+
+# GOOD: Use set -e for fail-fast
+set -e  # Exit on any error
+set -u  # Exit on undefined variable
+set -o pipefail  # Catch errors in pipes
+
+# GOOD: Trap for cleanup
+cleanup() {
+    rm -f "$TEMP_FILE"
+}
+trap cleanup EXIT INT TERM
+
+TEMP_FILE=$(mktemp)
+# ... use temp file ...
+# cleanup happens automatically
+```
+
+## Script Quality
+
+### Defensive Programming
+```bash
+# GOOD: Quote all variables
+rm -f "$file_path"  # Not: rm -f $file_path
+
+# GOOD: Use -- to separate options from arguments
+grep -r -- "$pattern" "$directory"
+
+# GOOD: Check variable is set
+: "${CONFIG_FILE:?CONFIG_FILE must be set}"
+
+# GOOD: Validate inputs
+if [ -z "$1" ]; then
+    echo "Usage: $0 <component_name>" >&2
+    exit 1
+fi
+```
+
+### Logging
+```bash
+# Use logger for syslog integration
+log_info() {
+    logger -t telemetry -p user.info "$*"
+}
+
+log_error() {
+    logger -t telemetry -p user.error "$*"
+    echo "ERROR: $*" >&2
+}
+
+# Usage
+log_info "Starting telemetry collection"
+if ! start_service; then
+    log_error "Failed to start service"
+    exit 1
+fi
+```
+
+## Testing Scripts
+
+### Use shellcheck
+```bash
+# Run shellcheck on all scripts
+shellcheck script.sh
+
+# In CI
+find . -name "*.sh" -exec shellcheck {} +
+```
+
+### Test on Target Platform
+- Test on actual embedded device or emulator
+- Verify with busybox tools
+- Check resource usage (memory, CPU)
+
+## Anti-Patterns
+
+```bash
+# BAD: Unquoted variables
+for file in $FILES; do  # Word splitting!
+    
+# GOOD: Quoted
+for file in "$FILES"; do
+
+# BAD: Parsing ls output
+for file in $(ls *.txt); do
+
+# GOOD: Use glob
+for file in *.txt; do
+
+# BAD: Useless use of cat
+cat file | grep pattern
+
+# GOOD: grep can read files
+grep pattern file
+
+# BAD: Not checking if file exists
+rm /tmp/file  # Error if doesn't exist
+
+# GOOD: Check or use -f
+rm -f /tmp/file  # Or: [ -f /tmp/file ] && rm /tmp/file
+```

+name: memory-safety-analyzer
+description: Analyze C/C++ code for memory safety issues including leaks, use-after-free, buffer overflows, and provide fixes. Use when reviewing memory management, debugging crashes, or improving code safety.
+---
+
+# Memory Safety Analysis for Embedded C
+
+## Purpose
+
+Systematically analyze C/C++ code for memory safety issues that can cause crashes, security vulnerabilities, or resource exhaustion in embedded systems.
+
+## Usage
+
+Invoke this skill when:
+- Reviewing new code with dynamic memory allocation
+- Debugging memory-related crashes
+- Analyzing legacy code for safety issues
+- Preparing code for production deployment
+- Investigating memory leaks or fragmentation
+
+## Analysis Process
+
+### Step 1: Identify All Allocations
+
+Search the code for:
+- `malloc`, `calloc`, `realloc`
+- `strdup`, `strndup`
+- `fopen`, `open`
+- `pthread_create`, `pthread_mutex_init`
+- Custom allocation functions
+
+For each allocation, verify:
+1. Return value is checked
+2. Corresponding free/close exists
+3. Error paths also free resources
+4. No double-free possible
+
+### Step 2: Check Pointer Lifetimes
+
+For each pointer variable:
+- When is it assigned?
+- When is it freed?
+- Can it be used after free?
+- Can it outlive the data it points to?
+- Is it NULL-initialized?
+- Is it NULL-checked before use?
+
+### Step 3: Analyze Error Paths
+
+For each error return:
+- Are all resources freed?
+- Is cleanup done in correct order?
+- Are error codes accurate?
+- Is logging appropriate?
+
+### Step 4: Review Buffer Operations
+
+For string and memory operations:
+- `strcpy` → should be `strncpy` with size check
+- `sprintf` → should be `snprintf` with size
+- `gets` → never use (remove immediately)
+- `strcat` → verify buffer size
+- `memcpy` → verify no overlap, validate size
+
+### Step 5: Static Analysis
+
+Run tools:
+```bash
+# Cppcheck
+cppcheck --enable=all --inconclusive file.c
+
+# Clang static analyzer
+scan-build make
+
+# Compiler warnings
+gcc -Wall -Wextra -Werror file.c
+```
+
+### Step 6: Dynamic Analysis
+
+Run valgrind:
+```bash
+valgrind --leak-check=full \
+         --show-leak-kinds=all \
+         --track-origins=yes \
+         --verbose \
+         ./program
+```
+
+## Common Issues and Fixes
+
+### Issue: Unchecked malloc
+
+```c
+// PROBLEM
+char* buffer = malloc(size);
+strcpy(buffer, input);  // Crash if malloc failed
+
+// FIX
+char* buffer = malloc(size);
+if (!buffer) {
+    log_error("Failed to allocate %zu bytes", size);
+    return ERR_NO_MEMORY;
+}
+strncpy(buffer, input, size - 1);
+buffer[size - 1] = '\0';
+```
+
+### Issue: Memory leak on error
+
+```c
+// PROBLEM
+int process() {
+    char* buf = malloc(1024);
+    FILE* f = fopen("file.txt", "r");
+    
+    if (!f) return -1;  // Leaked buf
+    
+    // ... process ...
+    
+    free(buf);
+    fclose(f);
+    return 0;
+}
+
+// FIX: Single exit with cleanup
+int process() {
+    int ret = 0;
+    char* buf = NULL;
+    FILE* f = NULL;
+    
+    buf = malloc(1024);
+    if (!buf) {
+        ret = ERR_NO_MEMORY;
+        goto cleanup;
+    }
+    
+    f = fopen("file.txt", "r");
+    if (!f) {
+        ret = ERR_FILE_OPEN;
+        goto cleanup;
+    }
+    
+    // ... process ...
+    
+cleanup:
+    free(buf);
+    if (f) fclose(f);
+    return ret;
+}
+```
+
+### Issue: Use after free
+
+```c
+// PROBLEM
+free(ptr);
+if (ptr->field > 0) { ... }  // Use after free!
+
+// FIX
+int value = ptr->field;
+free(ptr);
+ptr = NULL;
+if (value > 0) { ... }
+```
+
+### Issue: Double free
+
+```c
+// PROBLEM
+free(ptr);
+// ... later ...
+free(ptr);  // Double free!
+
+// FIX: NULL after free
+free(ptr);
+ptr = NULL;
+// ... later ...
+free(ptr);  // Safe: free(NULL) is a no-op
+```
+
+### Issue: Buffer overflow
+
+```c
+// PROBLEM
+char buffer[100];
+strcpy(buffer, user_input);  // Overflow if input > 99 chars
+
+// FIX
+char buffer[100];
+strncpy(buffer, user_input, sizeof(buffer) - 1);
+buffer[sizeof(buffer) - 1] = '\0';
+```
+
+## Output Format
+
+Provide findings as:
+
+```
+## Memory Safety Analysis
+
+### Critical Issues (must fix)
+1. [file.c:123] Unchecked malloc - potential NULL dereference
+2. [file.c:456] Memory leak on error path - buffer not freed
+3. [file.c:789] Use after free - ptr used after free()
+
+### Warnings (should fix)
+1. [file.c:234] strcpy used - prefer strncpy
+2. [file.c:567] Missing NULL check before pointer use
+
+### Recommendations
+1. Add cleanup label for resource management
+2. Use RAII wrapper in tests
+3. Run valgrind in CI pipeline
+
+### Suggested Fixes
+[Provide specific code changes for each issue]
+```
+
+## Verification
+
+After fixes:
+1. All static analysis warnings resolved
+2. Valgrind shows no leaks
+3. All tests pass
+4. Code review by human
+5. Memory footprint measured and acceptable

+description: Verify C/C++ code is platform-independent and portable across embedded platforms. Use when reviewing code for cross-platform deployment or preparing for new hardware targets.
+---
+
+# Platform Portability Checker
+
+## Purpose
+
+Ensure C/C++ code is portable across different embedded platforms, architectures, and operating systems without modification.
+
+## When to Use
+
+- Reviewing new code before merge
+- Porting to new hardware platform
+- Preparing release for multiple architectures
+- Investigating platform-specific bugs
+- Refactoring legacy platform-specific code
+
+## Portability Checklist
+
+### 1. Integer Types
+
+**Check for**: Use of `int`, `long`, `short` without fixed sizes
+
+```c
+// PROBLEM: Size varies by platform
+int counter;       // 16, 32, or 64 bits?
+long timestamp;    // 32 or 64 bits?
+short flag;        // 16 bits on most, but not guaranteed
+
+// FIX: Use stdint.h types
+#include <stdint.h>
+
+uint32_t counter;     // Always 32 bits
+uint64_t timestamp;   // Always 64 bits  
+uint16_t flag;        // Always 16 bits
+
+// For size_t operations
+size_t length;        // Pointer-sized unsigned
+ssize_t result;       // Pointer-sized signed
+```
+
+### 2. Pointer Assumptions
+
+**Check for**: Pointer arithmetic, casting, size assumptions
+
+```c
+// PROBLEM: Assumes pointer == long
+long ptr_value = (long)ptr;  // Fails on 64-bit with 32-bit long
+
+// FIX: Use uintptr_t
+#include <stdint.h>
+uintptr_t ptr_value = (uintptr_t)ptr;
+
+// PROBLEM: Pointer used as integer
+if (ptr & 0x1) { ... }  // What size is ptr?
+
+// FIX: Be explicit
+if ((uintptr_t)ptr & 0x1) { ... }
+```
+
+### 3. Endianness
+
+**Check for**: Multi-byte values sent over network or stored to disk
+
+```c
+// PROBLEM: Host byte order assumed
+uint32_t value = 0x12345678;
+fwrite(&value, 4, 1, file);  // Different on LE vs BE
+
+// FIX: Explicit byte order
+#include <arpa/inet.h>  // For htonl, ntohl
+
+uint32_t host_value = 0x12345678;
+uint32_t network_value = htonl(host_value);
+fwrite(&network_value, 4, 1, file);
+
+// For reading
+uint32_t network_value;
+fread(&network_value, 4, 1, file);
+uint32_t host_value = ntohl(network_value);
+```
+
+### 4. Structure Packing
+
+**Check for**: Structures sent over network or saved to disk
+
+```c
+// PROBLEM: Padding varies by platform
+struct {
+    uint8_t type;
+    uint32_t value;  // Padding before this?
+    uint16_t flags;  // Padding before this?
+} data;
+
+// FIX: Explicit packing
+struct __attribute__((packed)) {
+    uint8_t type;
+    uint32_t value;
+    uint16_t flags;
+} data;
+
+// Or control padding explicitly
+struct {
+    uint8_t type;
+    uint8_t padding[3];  // Explicit padding
+    uint32_t value;
+    uint16_t flags;
+    uint16_t padding2;
+} data;
+```
+
+### 5. Boolean Type
+
+**Check for**: Using int/char for boolean
+
+```c
+// PROBLEM: Non-standard boolean
+int flag;  // Really 3 states: 0, 1, other
+char enabled;  // Also used for booleans
+
+// FIX: Use stdbool.h
+#include <stdbool.h>
+
+bool flag;
+bool enabled;
+
+if (flag) { ... }  // Clear intent
+```
+
+### 6. Character Sets
+
+**Check for**: Assumptions about ASCII or character encoding
+
+```c
+// PROBLEM: Assumes ASCII
+if (ch >= 'A' && ch <= 'Z') {
+    ch = ch + 32;  // Convert to lowercase?
+}
+
+// FIX: Use standard functions
+#include <ctype.h>
+
+if (isupper(ch)) {
+    ch = tolower(ch);
+}
+```
+
+### 7. File Paths
+
+**Check for**: Hard-coded path separators
+
+```c
+// PROBLEM: Unix-specific
+const char* path = "/tmp/telemetry/data.log";
+
+// FIX: Use platform-agnostic approach
+#ifdef _WIN32
+    #define PATH_SEP "\\"
+    const char* tmp_dir = getenv("TEMP");
+#else
+    #define PATH_SEP "/"
+    const char* tmp_dir = "/tmp";
+#endif
+
+char path[256];
+snprintf(path, sizeof(path), "%s%stelemetry%sdata.log",
+         tmp_dir, PATH_SEP, PATH_SEP);
+```
+
+### 8. System Calls
+
+**Check for**: Platform-specific syscalls
+
+```c
+// PROBLEM: Linux-specific
+#include <sys/epoll.h>
+int fd = epoll_create(10);
+
+// FIX: Abstraction layer
+// In platform.h
+#if defined(__linux__)
+    #include "platform_linux.h"
+#elif defined(__APPLE__)
+    #include "platform_darwin.h"
+#else
+    #error "Unsupported platform"
+#endif
+
+// Each platform provides same interface
+event_loop_t* create_event_loop(void);
+```
+
+### 9. Compiler Extensions
+
+**Check for**: GCC/Clang specific features
+
+```c
+// PROBLEM: GCC-specific
+typeof(x) y = x;
+int array[0];  // Zero-length array
+
+// FIX: Avoid compiler-specific typeof/__auto_type; use standard types
+int y = x;  // declare with explicit type
+
+// Or avoid non-standard features
+// Define proper types instead
+```
+
+### 10. Include Paths
+
+**Check for**: Platform-specific headers
+
+```c
+// PROBLEM: Assumes Linux headers
+#include <linux/limits.h>
+
+// FIX: Use standard headers or configure check
+#ifdef HAVE_LINUX_LIMITS_H
+    #include <linux/limits.h>
+#else
+    #include <limits.h>
+#endif
+
+// Or use autoconf to detect
+// In configure.ac:
+// AC_CHECK_HEADERS([linux/limits.h limits.h])
+```
+
+## Build System Integration
+
+### configure.ac checks
+
+```autoconf
+# Check for required features
+AC_C_BIGENDIAN
+AC_CHECK_SIZEOF([int])
+AC_CHECK_SIZEOF([long])
+AC_CHECK_SIZEOF([void *])
+
+# Check for headers
+AC_CHECK_HEADERS([stdint.h stdbool.h endian.h])
+
+# Check for functions
+AC_CHECK_FUNCS([htonl ntohl])
+
+# Platform-specific code
+case "$host" in
+    *-linux*)
+        AC_DEFINE([PLATFORM_LINUX], [1])
+        ;;
+    arm*|*-arm*)
+        AC_DEFINE([PLATFORM_ARM], [1])
+        ;;
+esac
+```
+
+## Testing
+
+### Cross-Compilation Test
+
+```bash
+# Test building for different architectures
+./configure --host=arm-linux-gnueabihf
+make clean && make
+
+./configure --host=x86_64-linux-gnu
+make clean && make
+
+./configure --host=mips-linux-gnu
+make clean && make
+```
+
+### Endianness Test
+
+```c
+// Test endianness handling
+uint32_t value = 0x12345678;
+uint32_t network = htonl(value);
+uint32_t restored = ntohl(network);
+assert(value == restored);
+
+// Verify structure packing
+assert(sizeof(packed_struct_t) == EXPECTED_SIZE);
+```
+
+## Output Format
+
+```
+## Platform Portability Analysis
+
+### Critical Issues
+1. [file.c:123] Using `long` for timestamp - not fixed width
+2. [file.c:456] Writing struct directly to network - endianness issue
+3. [file.c:789] Assuming 32-bit pointers
+
+### Warnings
+1. [file.c:234] Using int for boolean - prefer stdbool.h
+2. [file.c:567] Hard-coded Unix path separator
+
+### Recommendations
+1. Add configure checks for required headers
+2. Create platform abstraction layer
+3. Test build on multiple architectures
+
+### Suggested Fixes
+[Specific code changes for each issue]
+```
+
+## Verification
+
+- Code compiles on target platforms
+- Tests pass on all platforms

+
+Run comprehensive quality checks in the standard test container through chat interface.
+
+## Quick Start
+
+Simply ask Copilot to run quality checks in natural language:
+
+```text
+Run quality checks
+```
+
+```text
+Check memory safety
+```
+
+```text
+Run static analysis on uploadstblogs/src
+```
+
+## What Gets Checked
+
+1. **Static Analysis**: cppcheck + shellcheck
+2. **Memory Safety**: valgrind leak detection
+3. **Thread Safety**: helgrind race/deadlock detection
+4. **Build Verification**: strict warnings compilation

+name: quality-checker
+description: Run comprehensive quality checks (static analysis, memory safety, thread safety, build verification) in the standard test container. Use when validating code changes or debugging before committing.
+---
+
+# Container-Based Quality Checker
+
+## Purpose
+
+Execute comprehensive quality checks on the codebase using the same containerized environment as CI/CD pipelines. Ensures consistency between local development and automated testing.
+
+## Usage
+
+Invoke this skill when:
+- Validating changes before committing
+- Debugging build or test failures
+- Running quality checks locally
+- Verifying memory safety of new code
+- Checking for thread safety issues
+- Performing static analysis
+
+You can run all checks or select specific ones based on your needs.
+
+## What It Does
+
+This skill runs quality checks inside the official test container (`ghcr.io/rdkcentral/docker-device-mgt-service-test/native-platform:latest`), which includes:
+- Build tools (gcc, g++, autotools, make)
+- Static analysis tools (cppcheck, shellcheck)
+- Memory analysis tools (valgrind)
+- Thread analysis tools (helgrind)
+- Google Test/Mock frameworks
+
+## Available Checks
+
+### 1. Static Analysis
+- **cppcheck**: Comprehensive C/C++ static code analyzer
+- **shellcheck**: Shell script linter
+- **Output**: XML report with findings
+
+### 2. Memory Safety (Valgrind)
+- **Memory leak detection**: Finds unreleased allocations
+- **Use-after-free detection**: Catches dangling pointer usage
+- **Invalid memory access**: Buffer overflows, uninitialized reads
+- **Output**: XML and log files per test binary
+
+### 3. Thread Safety (Helgrind)
+- **Race condition detection**: Finds unsynchronized shared memory access
+- **Deadlock detection**: Identifies lock ordering issues
+- **Lock usage verification**: Validates proper synchronization
+- **Output**: XML and log files per test binary
+
+### 4. Build Verification
+- **Strict compilation**: Builds with `-Wall -Wextra -Werror`
+- **Test build**: Verifies tests compile
+- **Binary analysis**: Reports size and dependencies
+- **Output**: Build artifacts and size report
+
+## Execution Process
+
+### Step 1: Setup Container Environment
+
+Pull the latest test container:
+```bash
+docker pull ghcr.io/rdkcentral/docker-device-mgt-service-test/native-platform:latest
+```
+
+Start container with workspace mounted:
+```bash
+docker run -d --name native-platform \
+  -v /path/to/workspace:/mnt/workspace \
+  ghcr.io/rdkcentral/docker-device-mgt-service-test/native-platform:latest
+```
+
+### Step 2: Run Selected Checks
+
+Execute the requested quality checks inside the container:
+
+**Static Analysis:**
+```bash
+docker exec -i native-platform /bin/bash -c "
+  cd /mnt/workspace && \
+  cppcheck --enable=all \
+           --inconclusive \
+           --suppress=missingIncludeSystem \
+           --suppress=unmatchedSuppression \
+           --error-exitcode=0 \
+           --xml \
+           --xml-version=2 \
+           . 2> cppcheck-report.xml
+"
+```
+
+**Shell Script Checks:**
+```bash
+docker exec -i native-platform /bin/bash -c "
+  cd /mnt/workspace && \
+  find . -name '*.sh' -type f -exec shellcheck {} +
+"
+```
+
+**Memory Safety:**
+```bash
+docker exec -i native-platform /bin/bash -c "
+  cd /mnt/workspace && \
+  autoreconf -fi && \
+  ./configure --enable-gtest && \
+  make -j\$(nproc) && \
+  find unittest uploadstblogs/unittest -type f -executable -name '*gtest*' 2>/dev/null | while read test_bin; do
+    valgrind --leak-check=full \
+             --show-leak-kinds=all \
+             --track-origins=yes \
+             --xml=yes \
+             --xml-file=\"valgrind-\$(basename \$test_bin).xml\" \
+             \"\$test_bin\" 2>&1 | tee \"valgrind-\$(basename \$test_bin).log\"
+  done
+"
+```
+
+**Thread Safety:**
+```bash
+docker exec -i native-platform /bin/bash -c "
+  cd /mnt/workspace && \
+  find unittest uploadstblogs/unittest -type f -executable -name '*gtest*' 2>/dev/null | while read test_bin; do
+    valgrind --tool=helgrind \
+             --track-lockorders=yes \
+             --xml=yes \
+             --xml-file=\"helgrind-\$(basename \$test_bin).xml\" \
+             \"\$test_bin\" 2>&1 | tee \"helgrind-\$(basename \$test_bin).log\"
+  done
+"
+```
+
+**Build Verification:**
+```bash
+docker exec -i native-platform /bin/bash -c "
+  cd /mnt/workspace && \
+  autoreconf -fi && \
+  ./configure --enable-gtest CFLAGS='-Wall -Wextra -Werror' CXXFLAGS='-Wall -Wextra -Werror' && \
+  make -j\$(nproc) && \
+  if [ -f 'dcmd' ]; then
+    ls -lh dcmd
+    file dcmd
+    size dcmd
+  fi
+  if [ -f 'uploadstblogs/src/uploadstblogs' ]; then
+    ls -lh uploadstblogs/src/uploadstblogs
+    file uploadstblogs/src/uploadstblogs
+  fi
+"
+```
+
+### Step 3: Report Results
+
+Parse and summarize results for the user:
+- Number of issues found by category
+- Critical issues requiring immediate attention
+- Warnings that should be addressed
+- Memory leaks with stack traces
+- Race conditions or deadlock risks
+- Build errors or warnings
+
+### Step 4: Cleanup
+
+Stop and remove the container:
+```bash
+docker stop native-platform
+docker rm native-platform
+```
+
+## Interpreting Results
+
+### Static Analysis (cppcheck)
+- **error**: Critical issues that must be fixed
+- **warning**: Potential problems to review
+- **style**: Code style improvements
+- **performance**: Optimization opportunities
+
+### Memory Safety (Valgrind)
+- **definitely lost**: Memory leaks requiring fixes
+- **indirectly lost**: Leaks from lost parent structures
+- **possibly lost**: Potential leaks to investigate
+- **still reachable**: Memory held at exit (usually OK)
+- **Invalid read/write**: Buffer overflow (CRITICAL)
+- **Use of uninitialized value**: Must initialize before use
+
+### Thread Safety (Helgrind)
+- **Possible data race**: Unsynchronized access to shared data
+- **Lock order violation**: Potential deadlock scenario
+- **Unlocking unlocked lock**: Synchronization bug
+- **Thread still holds locks**: Resource leak
+
+### Build Verification
+- **Compilation errors**: Must fix before proceeding
+- **Warnings**: Review and fix (builds with -Werror)
+- **Binary size**: Monitor for embedded constraints
+
+## User Interaction
+
+When invoked, ask the user:
+
+1. **Which checks to run?**
+   - All checks (comprehensive)
+   - Static analysis only (fast)
+   - Memory safety only
+   - Thread safety only
+   - Build verification only
+   - Custom combination
+
+2. **Scope:**
+   - Full codebase
+   - Specific directories
+   - Recently changed files
+
+3. **Report detail:**
+   - Summary only (counts and critical issues)
+   - Detailed (all findings)
+   - Full raw output
+
+## Example Invocations
+
+**User**: "Run quality checks"
+- Default: Run all checks on full codebase, provide summary
+
+**User**: "Check memory safety"
+- Run only valgrind checks, detailed report
+
+**User**: "Quick static analysis"
+- Run cppcheck and shellcheck, summary only
+
+**User**: "Verify my changes build"
+- Run build verification with strict warnings
+
+**User**: "Full analysis on uploadstblogs/src"
+- Run all checks scoped to uploadstblogs directory
+
+## Best Practices
+
+1. **Run before committing**: Catch issues early
+2. **Start with static analysis**: Fastest feedback
+3. **Run memory checks on test binaries**: Most effective
+4. **Review thread safety for concurrent code**: Essential for multi-threaded components
+5. **Monitor binary size**: Important for embedded targets
+
+## Integration with Development Workflow
+
+1. **Pre-commit**: Quick static analysis
+2. **Pre-push**: Full quality check suite
+3. **Debugging**: Targeted memory/thread analysis
+4. **Code review**: Validate reviewer feedback
+5. **Refactoring**: Ensure no regressions
+
+## Advantages Over Manual Testing
+
+- **Consistency**: Same environment as CI/CD
+- **Completeness**: All tools in one command
+- **Reproducibility**: Container ensures identical results
+- **Efficiency**: No local tool installation needed
+- **Confidence**: Pass locally = pass in CI
+
+## Output Files Generated
+
+- `cppcheck-report.xml`: Static analysis findings
+- `valgrind-<testname>.xml`: Memory issues per test
+- `valgrind-<testname>.log`: Detailed memory logs
+- `helgrind-<testname>.xml`: Thread safety issues per test
+- `helgrind-<testname>.log`: Detailed concurrency logs
+
+These files can be uploaded as artifacts or reviewed locally.
+
+## Limitations
+
+- Requires Docker with GitHub Container Registry access
+- Container pulls can be slow on first run (cached afterward)
+- Full suite can take several minutes depending on codebase size
+- Valgrind slows execution significantly (expected)
+
+## Tips for Faster Execution
+
+1. Use cached container images (don't pull every time)
+2. Run static analysis first (fastest)
+3. Scope checks to changed directories
+4. Run memory/thread checks only on affected tests
+5. Use parallel execution where possible
+
+## Skill Execution Logic
+
+When user invokes this skill:
+
+1. **Authenticate with GitHub Container Registry**
+   - Use github.actor and GITHUB_TOKEN if available
+   - Otherwise prompt for credentials or skip private registries
+
+2. **Pull container image**
+   - Check if image exists locally
+   - Pull only if needed or if --force specified
+
+3. **Start container**
+   - Mount workspace at /mnt/workspace
+   - Use unique container name (quality-checker-<timestamp>)
+   - Run in detached mode
+
+4. **Execute requested checks**
+   - Run checks in sequence
+   - Capture output
+   - Continue on errors (collect all findings)
+
+5. **Collect results**
+   - Copy result files from container
+   - Parse XML/log outputs
+   - Categorize findings
+
+6. **Report to user**
+   - Summary count
+   - Critical issues highlighted
+   - Link to detailed reports
+   - Next steps recommendations
+
+7. **Cleanup**
+   - Stop container
+   - Remove container
+   - Optional: clean up result files
+
+## Error Handling
+
+- **Container pull fails**: Report error, suggest manual pull
+- **Container start fails**: Check Docker daemon, ports, permissions
+- **Build fails**: Report build errors, stop further checks
+- **Tools missing**: Verify container version, report missing tools
+- **Out of memory**: Suggest increasing Docker memory limit

+## Documentation Process
+
+### Step 1: Analyze the Code
+
+Before writing documentation:
+
+1. **Read the source code** - Understand implementation
+2. **Identify key abstractions** - Classes, structs, modules
+3. **Map dependencies** - What calls what, data flow
+4. **Find synchronization** - Mutexes, conditions, atomics
+5. **Trace resource lifecycle** - Allocations, ownership, cleanup
+6. **Review existing docs** - Check for patterns and style
+
+### Step 2: Create Structure
+
+For each component:
+
+```markdown

+```
+
+### Step 4: Add Code Examples
+
+Provide clear, compilable examples:
+
+#### Good Example Structure
+```markdown
+### Example: Creating a Profile
+
+This example shows how to create and configure a telemetry profile.
+
+**Prerequisites:**
+- Telemetry system initialized
+- Valid configuration file
+
+**Code:**
+```c
+#include "profile.h"
+#include <stdio.h>
+
+int main(void) {
+    profile_t* profile = NULL;
+    int ret = 0;
+    
+    // Create profile with name and interval
+    ret = profile_create("MyProfile", 60, &profile);
+    if (ret != 0) {
+        fprintf(stderr, "Failed to create profile: %d\n", ret);
+        return -1;
+    }
+    
+    // Add marker to profile
+    ret = profile_add_marker(profile, "Component.Status", 
+                            MARKER_TYPE_COMPONENT);
+    if (ret != 0) {
+        fprintf(stderr, "Failed to add marker: %d\n", ret);
+        profile_destroy(profile);
+        return -1;
+    }
+    
+    // Activate profile
+    ret = profile_activate(profile);
+    if (ret != 0) {
+        fprintf(stderr, "Failed to activate profile: %d\n", ret);
+        profile_destroy(profile);
+        return -1;
+    }
+    
+    printf("Profile created and activated successfully\n");
+    
+    // Cleanup
+    profile_destroy(profile);
+    return 0;
+}
+```
+
+**Expected Output:**
+```
+Profile created and activated successfully
+```
+
+**Notes:**
+- Always check return values
+- Call profile_destroy() even on error paths
+- Profile name must be unique
+
+### Step 5: Document APIs
+
+For each public function:
+
+```markdown
+### profile_create()
+
+Creates a new telemetry profile.
+
+**Signature:**
+```c
+int profile_create(const char* name, 
+                  unsigned int interval_sec,
+                  profile_t** out_profile);
+```
+
+**Parameters:**
+- `name` - Unique profile name (max 63 chars, non-NULL)
+- `interval_sec` - Reporting interval in seconds (min: 60, max: 86400)
+- `out_profile` - Output pointer to created profile (must be non-NULL)
+
+**Returns:**
+- `0` - Success
+- `-EINVAL` - Invalid parameter (NULL name/out_profile, invalid interval)
+- `-ENOMEM` - Memory allocation failed
+- `-EEXIST` - Profile with same name already exists
+
+**Thread Safety:**
+Thread-safe. Uses internal mutex for profile list management.
+
+**Memory:**
+Allocates memory for profile structure and name copy. Caller must call 
+`profile_destroy()` to free resources.
+
+**Example:**
+See [Example: Creating a Profile](#example-creating-a-profile)
+
+**See Also:**
+- profile_destroy()
+- profile_activate()
+- profile_add_marker()
+```
+
+### Step 6: Document Threading
+
+For multi-threaded components:
+
+```markdown
+## Threading Model
+
+### Thread Overview
+
+| Thread Name | Purpose | Priority | Stack Size |
+|------------|---------|----------|------------|
+| Main | Initialization, message loop | Normal | Default |
+| XConf Fetch | Configuration retrieval | Low | 64KB |
+| Report Send | HTTP report transmission | Low | 64KB |
+| Event Receiver | Marker event processing | High | 32KB |
+
+### Synchronization Primitives
+
+```c
+// Global mutexes
+static pthread_mutex_t pool_mutex = PTHREAD_MUTEX_INITIALIZER;
+static pthread_mutex_t profile_mutex = PTHREAD_MUTEX_INITIALIZER;
+
+// Condition variables
+static pthread_cond_t pool_cond = PTHREAD_COND_INITIALIZER;
+static pthread_cond_t xconf_cond = PTHREAD_COND_INITIALIZER;
+```
+
+### Lock Ordering
+
+To prevent deadlocks, always acquire locks in this order:
+
+1. `profile_mutex` (profile list)
+2. `pool_mutex` (connection pool)
+3. Individual profile locks
+
+**Example:**
+```c
+// CORRECT: Proper lock ordering
+pthread_mutex_lock(&profile_mutex);
+profile_t* p = find_profile_locked(name);
+pthread_mutex_lock(&pool_mutex);
+// ... use both resources ...
+pthread_mutex_unlock(&pool_mutex);
+pthread_mutex_unlock(&profile_mutex);
+
+// WRONG: Deadlock risk!
+pthread_mutex_lock(&pool_mutex);
+pthread_mutex_lock(&profile_mutex);  // May deadlock!
+```
+
+### Thread Safety Guarantees
+
+| Function | Thread Safety | Notes |
+|----------|---------------|-------|
+| profile_create() | Thread-safe | Uses profile_mutex |
+| profile_destroy() | Thread-safe | Uses profile_mutex |
+| profile_add_marker() | Not thread-safe | Call before activation only |
+| send_report() | Thread-safe | Uses pool_mutex |
+```
+
+### Step 7: Document Memory Management
+
+```markdown
+## Memory Management
+
+### Allocation Patterns
+
+```mermaid
+graph TD
+    A[profile_create] --> B[malloc profile_t]
+    B --> C[strdup name]
+    B --> D[malloc markers array]
+    E[profile_add_marker] --> F[realloc markers]
+    G[profile_destroy] --> H[free markers]
+    H --> I[free name]
+    I --> J[free profile_t]
+```
+
+### Ownership Rules
+
+1. **profile_t**: Owned by caller after profile_create()
+2. **Marker strings**: Copied; caller retains original ownership
+3. **Report data**: Owned by sender; freed after transmission
+
+### Lifecycle Example
+
+```c
+// Creation phase
+profile_t* prof = NULL;
+profile_create("test", 60, &prof);  // Allocates memory
+
+// Configuration phase
+profile_add_marker(prof, "mark1", TYPE_EVENT);  // May realloc
+profile_add_marker(prof, "mark2", TYPE_EVENT);  // May realloc
+
+// Active phase - no allocations
+profile_activate(prof);
+
+// Destruction phase
+profile_destroy(prof);  // Frees all memory
+prof = NULL;            // Prevent use-after-free
+```
+
+### Memory Budget
+
+Typical memory usage per component:
+
+| Component | Static | Dynamic (per item) | Notes |
+|-----------|--------|-------------------|-------|
+| Profile | 128 bytes | +32 bytes/marker | Preallocated list |
+| Connection Pool | 512 bytes | +256 bytes/handle | Max 5 handles |
+| Report Buffer | 0 | 64KB | Temporary, freed after send |
+
+**Total typical footprint**: ~150KB (5 profiles, 3 connections, 1 report)
+```
+
+## Best Practices
+
+### Writing Style
+
+1. **Be Concise**: Get to the point quickly
+2. **Be Specific**: Use exact terms, not vague descriptions
+3. **Be Accurate**: Test all code examples
+4. **Be Complete**: Don't leave critical details unstated
+5. **Be Consistent**: Follow established patterns
+
+### Code Examples
+
+- **Always compile-test** examples before documenting
+- **Show error handling** - embedded systems need robust code
+- **Include cleanup** - demonstrate proper resource management
+- **Add context** - explain when/why to use the code
+- **Keep focused** - one example, one concept
+
+### Diagrams
+
+- **Use Mermaid** for all diagrams (version control friendly)
+- **Keep simple** - max 10-12 nodes per diagram
+- **Label clearly** - all arrows and nodes need names
+- **Show flow** - make direction obvious
+- **Add legends** - explain symbols if needed
+

+- mTLS via OpenSSL 1.1.1+
+
+### RDKB Devices
+- Integration with RDK logger (rdk_debug.h)
+- Uses RBUS for IPC when available
+- Memory constraints: limit to 8 profiles max
+
+### Constraints
+- **Memory**: Tested with 64MB minimum
+- **CPU**: ARMv7 or better
+- **Storage**: 1MB for logs and cache

+
+## Quality Checklist
+
+Before considering documentation complete:
+
+- [ ] All public APIs documented with signatures
+- [ ] At least one working code example per major function
+- [ ] Thread safety explicitly stated
+- [ ] Memory ownership clearly documented
+- [ ] Error codes and meanings listed
+- [ ] Diagrams for complex flows
+- [ ] Cross-references to related docs
+- [ ] Platform-specific notes included
+- [ ] Code examples compile and run
+- [ ] Grammar and spelling checked

+
+## Maintenance
+
+Documentation is code:
+
+1. **Update with code changes** - docs and code change together
+2. **Version documentation** - tag with releases
+3. **Review periodically** - ensure accuracy quarterly
+4. **Fix broken links** - validate references
+5. **Deprecate carefully** - mark old features clearly
+
+### Deprecation Notice Template
+
+```markdown
+## DEPRECATED: old_function()
+
+⚠️ **This function is deprecated as of v2.1.0**
+
+**Reason**: Memory leak risk in error paths
+
+**Alternative**: Use new_function() instead
+
+**Migration Example**:
+```c
+// Old way (deprecated)
+old_function(param);
+
+// New way
+new_function(param);
+```
+
+**Removal**: Scheduled for v3.0.0 (Est. Q2 2026)
+```
+
+## Tools Integration
+
+### Generate API Docs from Code
+
+Use Doxygen-style comments in code:
+
+```c
+/**
+ * @brief Create a new telemetry profile
+ * 
+ * Creates and initializes a profile structure. The caller is responsible
+ * for destroying the profile with profile_destroy() when done.
+ * 
+ * @param[in]  name         Unique profile name (max 63 chars)
+ * @param[in]  interval_sec Reporting interval (60-86400 seconds)
+ * @param[out] out_profile  Pointer to receive created profile

+```
+
+### Diagram Tools
+
+- **Mermaid Live Editor**: https://mermaid.live
+- **VS Code Markdown Preview**: Built-in mermaid support
+- **Documentation generators**: Can embed mermaid in output
+
+## Troubleshooting Common Documentation Issues
+
+### Issue: Code example doesn't compile
+
+**Solution**: Always test examples in isolation
+```bash
+# Extract example to test file
+cat > test_example.c << 'EOF'
+[paste example code]
+EOF
+
+# Compile with project flags
+gcc -Wall -Wextra -I../include test_example.c -o test_example
+
+# Run to verify
+./test_example
+```
+
+### Issue: Diagram is too complex
+
+**Solution**: Break into multiple diagrams
+- One high-level overview diagram
+- Multiple focused detail diagrams
+- Link them together in text
+
+### Issue: Outdated documentation
+
+**Solution**: Add CI check
+```bash
+# Check for TODOs in docs
+grep -r "TODO\|FIXME\|XXX" docs/ && exit 1
+
+# Check for broken links
+markdown-link-check docs/**/*.md
+```

+description: Analyze C/C++ code for thread safety issues including race conditions, deadlocks, and improper synchronization. Use when reviewing concurrent code or debugging threading issues.
+---
+
+# Thread Safety Analysis for Embedded C
+
+## Purpose
+
+Systematically analyze C/C++ code for thread safety issues that can cause race conditions, deadlocks, or performance degradation in embedded systems.
+
+## Usage
+
+Invoke this skill when:
+- Reviewing multi-threaded code
+- Debugging race conditions or deadlocks
+- Optimizing synchronization overhead
+- Validating thread creation and cleanup
+- Investigating lock contention issues
+
+## Analysis Process
+
+### Step 1: Identify Shared Data
+
+Search for global and static variables:
+- Global variables (especially non-const)
+- Static variables in functions
+- Shared heap allocations
+- Reference-counted objects
+
+For each shared variable, verify:
+1. How is it protected (mutex, atomic, etc.)?
+2. Is the protection consistent across all accesses?
+3. Are reads and writes both protected?
+4. Is initialization thread-safe?
+
+### Step 2: Review Thread Creation
+
+Check all pthread_create calls:
+- Are thread attributes used?
+- Is stack size specified?
+- Are threads detached or joinable?
+- Is cleanup properly handled?
+
+```c
+// CHECK FOR:
+pthread_t thread;
+pthread_create(&thread, NULL, func, arg);  // BAD: No attributes
+
+// SHOULD BE:
+pthread_attr_t attr;
+pthread_attr_init(&attr);
+pthread_attr_setstacksize(&attr, 64 * 1024);  // Explicit size
+pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED);
+pthread_create(&thread, &attr, func, arg);
+pthread_attr_destroy(&attr);
+```
+
+### Step 3: Analyze Lock Usage
+
+For each mutex/rwlock:
+- Is it initialized before use?
+- Is it destroyed when done?
+- Are lock/unlock pairs balanced?
+- What is the lock ordering?
+- Are locks held during expensive operations?
+
+Common patterns to check:
+```c
+// Pattern 1: Missing unlock on error path
+pthread_mutex_lock(&lock);
+if (error) return -1;  // LEAK!
+pthread_mutex_unlock(&lock);
+
+// Pattern 2: Lock ordering violation
+// Thread 1:
+pthread_mutex_lock(&a);
+pthread_mutex_lock(&b);
+
+// Thread 2:
+pthread_mutex_lock(&b);  // Different order!
+pthread_mutex_lock(&a);  // DEADLOCK RISK!
+
+// Pattern 3: Heavy lock for simple operation
+pthread_rwlock_wrlock(&lock);  // Too heavy
+counter++;
+pthread_rwlock_unlock(&lock);
+// Should use atomic_int instead
+```
+
+### Step 4: Check for Race Conditions
+
+Look for unprotected accesses to shared data:
+
+```c
+// RACE: Read-modify-write without protection
+if (shared_flag == 0) {  // Thread 1 reads
+    shared_flag = 1;     // Thread 2 also reads before Thread 1 writes
+}
+
+// FIX: Use atomic or lock
+pthread_mutex_lock(&lock);
+if (shared_flag == 0) {
+    shared_flag = 1;
+}
+pthread_mutex_unlock(&lock);
+
+// OR: Use atomic compare-and-swap
+int expected = 0;
+atomic_compare_exchange_strong(&shared_flag, &expected, 1);
+```
+
+### Step 5: Verify Atomic Usage
+
+For atomic variables:
+- Are they declared with proper type (atomic_int, atomic_bool)?
+- Is memory ordering appropriate?
+- Are non-atomic operations mixed with atomic ones?
+
+```c
+// CHECK:
+atomic_int counter;
+
+// GOOD: Atomic operations
+atomic_fetch_add(&counter, 1);
+int value = atomic_load(&counter);
+
+// BAD: Mixing atomic and non-atomic
+counter++;  // Non-atomic! Use atomic_fetch_add
+```
+
+### Step 6: Deadlock Detection
+
+Check for common deadlock patterns:
+
+1. **Circular wait**: Lock A → Lock B, Lock B → Lock A
+2. **Lock held while waiting**: Mutex held during sleep/wait
+3. **Missing timeout**: Indefinite blocking without timeout
+4. **Signal under lock**: Condition signal while holding mutex
+
+```c
+// Deadlock Pattern 1: Circular dependency
+// Function 1:
+lock(mutex_a);
+lock(mutex_b);  // Order: A, B
+
+// Function 2:
+lock(mutex_b);
+lock(mutex_a);  // Order: B, A - DEADLOCK!
+
+// Deadlock Pattern 2: Lock held during expensive operation
+lock(mutex);
+expensive_network_call();  // Blocks other threads!
+unlock(mutex);
+
+// Deadlock Pattern 3: No timeout
+pthread_mutex_lock(&lock);  // Waits forever if deadlock
+```
+
+### Step 7: Check Condition Variables
+
+For condition variables:
+- Is wait always in a loop?
+- Is predicate checked before and after wait?
+- Is signal/broadcast done correctly?
+- Is spurious wakeup handled?
+
+```c
+// GOOD: Proper condition variable usage
+pthread_mutex_lock(&mutex);
+while (!condition) {  // Loop for spurious wakeups
+    pthread_cond_wait(&cond, &mutex);
+}
+// ... use protected data ...
+pthread_mutex_unlock(&mutex);
+
+// Signal:
+pthread_mutex_lock(&mutex);
+condition = true;
+pthread_cond_signal(&cond);
+pthread_mutex_unlock(&mutex);
+
+// BAD: Missing loop
+pthread_mutex_lock(&mutex);
+if (!condition) {  // Should be 'while'!
+    pthread_cond_wait(&cond, &mutex);
+}
+pthread_mutex_unlock(&mutex);
+```
+
+## Common Issues and Fixes
+
+### Issue: Default Thread Stack Size
+
+```c
+// PROBLEM: Wastes memory (8MB per thread)
+pthread_t thread;
+pthread_create(&thread, NULL, worker, arg);
+
+// FIX: Specify minimal stack size
+pthread_attr_t attr;
+pthread_attr_init(&attr);
+pthread_attr_setstacksize(&attr, 64 * 1024);  // 64KB
+pthread_create(&thread, &attr, worker, arg);
+pthread_attr_destroy(&attr);
+```
+
+### Issue: Heavy Synchronization
+
+```c
+// PROBLEM: Reader-writer lock overkill
+pthread_rwlock_t lock;
+int counter;
+
+void increment() {
+    pthread_rwlock_wrlock(&lock);
+    counter++;
+    pthread_rwlock_unlock(&lock);
+}
+
+// FIX: Use atomic operations
+atomic_int counter;
+
+void increment() {
+    atomic_fetch_add(&counter, 1);  // No lock needed
+}
+```
+
+### Issue: Lock Ordering Violation
+
+```c
+// PROBLEM: Different lock orders cause deadlock
+// Thread 1:
+void process_a_then_b() {
+    lock(&resource_a.lock);
+    lock(&resource_b.lock);
+    // ...
+}
+
+// Thread 2:
+void process_b_then_a() {
+    lock(&resource_b.lock);
+    lock(&resource_a.lock);  // DEADLOCK!
+    // ...
+}
+
+// FIX: Consistent ordering everywhere

+
+### Issue: Race in Lazy Initialization
+
+```c
+// PROBLEM: Non-thread-safe initialization
+static config_t* config = NULL;
+
+config_t* get_config() {
+    if (!config) {  // Race here!
+        config = malloc(sizeof(config_t));
+        init_config(config);
+    }
+    return config;
+}
+
+// FIX: Use pthread_once
+static pthread_once_t init_once = PTHREAD_ONCE_INIT;
+static config_t* config = NULL;
+
+static void init_config_once() {
+    config = malloc(sizeof(config_t));
+    init_config(config);
+}
+
+config_t* get_config() {
+    pthread_once(&init_once, init_config_once);
+    return config;
+}
+```
+
+### Issue: Missing Lock on Error Path
+
+```c
+// PROBLEM: Lock not released on error
+int process_data(data_t* shared) {
+    pthread_mutex_lock(&shared->lock);
+    
+    if (validate(shared) != 0) {
+        return -1;  // BUG: Lock not released!
+    }
+    
+    update(shared);
+    pthread_mutex_unlock(&shared->lock);
+    return 0;
+}
+
+// FIX: Unlock on all paths
+int process_data(data_t* shared) {
+    int ret = 0;
+    
+    pthread_mutex_lock(&shared->lock);
+    
+    if (validate(shared) != 0) {
+        ret = -1;
+        goto cleanup;
+    }
+    
+    update(shared);
+    
+cleanup:
+    pthread_mutex_unlock(&shared->lock);
+    return ret;
+}
+```
+
+### Issue: Long Critical Section
+
+```c
+// PROBLEM: Expensive operation under lock
+pthread_mutex_lock(&lock);
+for (int i = 0; i < 1000000; i++) {
+    compute();  // Blocks other threads!
+}
+shared_result = final_value;
+pthread_mutex_unlock(&lock);
+
+// FIX: Minimize critical section
+int result = 0;
+for (int i = 0; i < 1000000; i++) {
+    result += compute();  // No lock
+}
+
+pthread_mutex_lock(&lock);
+shared_result = result;  // Lock only for update
+pthread_mutex_unlock(&lock);
+```
+
+## Testing for Thread Safety
+
+### Compile with Thread Sanitizer
+
+```bash
+# Build with thread sanitizer
+gcc -g -fsanitize=thread -O1 source.c -o program -lpthread
+
+# Run
+./program
+
+# Will report:
+# - Data races
+# - Lock ordering issues
+# - Potential deadlocks
+```
+
+### Run Helgrind
+
+```bash
+# Check for thread safety issues
+valgrind --tool=helgrind \
+         --track-lockorders=yes \
+         ./program
+
+# Reports:
+# - Race conditions
+# - Lock order violations
+# - Possible deadlocks
+```
+
+### Stress Testing
+
+```c
+// Test under high concurrency
+#define NUM_THREADS 100
+#define ITERATIONS 10000
+
+void stress_test() {
+    pthread_t threads[NUM_THREADS];
+    
+    for (int i = 0; i < NUM_THREADS; i++) {
+        pthread_create(&threads[i], NULL, worker, NULL);
+    }
+    
+    for (int i = 0; i < NUM_THREADS; i++) {
+        pthread_join(threads[i], NULL);
+    }
+    
+    // Verify invariants
+    assert(shared_counter == NUM_THREADS * ITERATIONS);
+}
+```
+
+## Output Format
+
+Provide findings as:
+
+```
+## Thread Safety Analysis
+
+### Critical Issues (must fix)
+1. [file.c:123] Race condition - unprotected access to shared_flag
+2. [file.c:456] Deadlock potential - lock order violation (A→B vs B→A)
+3. [file.c:789] Lock leak - mutex not released on error path
+
+### Warnings (should fix)
+1. [file.c:234] Default thread stack - wastes 8MB per thread
+2. [file.c:567] Heavy lock - use atomic_int instead of mutex
+3. [file.c:890] Long critical section - holds lock during I/O
+
+### Recommendations
+1. Establish lock ordering convention (document in header)
+2. Use pthread_once for singleton initialization
+3. Replace reader-writer locks with atomics for counters
+4. Add thread sanitizer to CI pipeline
+
+### Suggested Fixes
+[Provide specific code changes for each issue]
+```
+
+## Verification
+
+After fixes:
+1. Thread sanitizer shows no errors
+2. Helgrind reports clean
+3. Stress tests pass consistently
+4. Lock contention metrics acceptable
+5. No deadlocks under load testing
+6. Code review confirms thread safety

+description: >
+  Triage any dcm-agent behavioral issue on RDK devices by correlating device
+  log bundles with source code. Covers daemon hangs, log upload failures,
+  DCM configuration errors, uploadSTBLogs failures, backup_logs issues,
+  USB log upload problems, RBUS communication errors, and cron scheduling
+  issues. The user states the issue; this skill guides systematic root-cause
+  analysis regardless of issue type.
+---
+
+# Log Triage Skill
+
+## Purpose
+
+Systematically correlate device log bundles with dcm-agent source code to
+identify root causes, characterize impact, and propose unit-test and
+functional-test reproduction scenarios — for **any** behavioral anomaly reported
+by the user.
+
+---
+
+## Usage
+
+Invoke this skill when:
+- A device log bundle is available under `logs/` (or attached separately)
+- The user describes a behavioral anomaly (examples: DCM daemon not starting,
+  log upload failures, configuration parsing errors, upload retry loops,
+  authentication failures, backup logs not working, USB upload issues, cron
+  job scheduling problems, RBUS communication failures)
+- You need to write a reproduction scenario for an existing or proposed fix
+
+**The user's stated issue drives the investigation.** Do not assume a specific
+failure mode — read the issue description first, then follow the steps below.
+
+---
+
+## Step 1: Orient to the Log Bundle
+
+**Log bundle layout** (typical RDK device):
+```
+logs/<MAC>/<SESSION_TIMESTAMP>/logs/
+    dcm.log.0                      ← Primary DCM daemon log (start here)
+    uploadstblogs.log.0            ← uploadSTBLogs log upload execution
+    dcmscript.log.0                ← DCM script execution logs
+    backup_logs.log.0              ← Log backup operations
+    usb_logupload.log.0            ← USB log upload operations
+    messages.txt.0                 ← System messages
+    top_log.txt.0                  ← CPU/memory snapshots
+    /opt/logs/                     ← Actual log files being uploaded
+    /nvram/DCMresponse.txt         ← DCM configuration from XConf
+    /nvram/dcm.properties          ← DCM settings
+```
+
+Include any log files surfaced by the user's issue description.
+
+**Log timestamp prefix format**: `YYMMDD-HH:MM:SS` or RFC3339
+- Session folder names are **local-time snapshots** (format: `MM-DD-YY-HH:MMxM`)
+- Log lines use device local time
+
+---
+
+## Step 2: Map Daemon Startup and Components
+
+Read the startup section of `dcm.log.0` (first ~50 lines) to identify:
+
+| What to find | Log pattern |
+|---|---|
+| Daemon start | `DCM daemon starting` or `dcmDaemonMainInit` |
+| Configuration loaded | `DCMresponse.txt` parsing |
+| RBUS initialization | `rbus_open` or `RBUS_Initialize` |
+| Cron job scheduling | `dcm_cronparse` or cron expression parsing |
+| Log upload schedule | `DCM_LOG_UPLOAD` schedule setup |
+| Firmware update schedule | `DCM_FW_UPDATE` schedule setup |
+
+**Key components in dcm-agent**:
+- Main daemon (`dcmd`) — initialization, configuration, RBUS, cron scheduling
+- uploadSTBLogs — log collection, archiving, upload execution
+- uploadLogsNow — on-demand log upload trigger
+- backup_logs — log backup and rotation
+- usbLogUpload — USB-based log upload
+- dcm_rbus — RBUS interface for remote control
+
+---
+
+## Step 3: Identify the Anomaly Window
+
+Based on the **user's stated issue**, search for the relevant evidence pattern:
+
+### DCM Daemon Not Starting / Crashes
+```bash
+grep -n "dcmDaemonMainInit\|ERROR\|FATAL\|Segmentation\|core dump" dcm.log.0
+grep -n "dcmd" messages.txt.0 | tail -50
+```
+Check for:
+- Configuration file missing or malformed (`/nvram/DCMresponse.txt`)
+- RBUS initialization failure
+- Memory allocation failures
+- Dependency library missing (rbus, curl, ssl)
+
+### Log Upload Failures
+```bash
+grep -n "uploadSTBLogs\|upload\|ERROR\|HTTP\|curl\|Failed" uploadstblogs.log.0
+grep -n "S3\|presign\|mTLS\|OAuth\|authentication" uploadstblogs.log.0
+```
+Look for:
+- HTTP status codes (4xx client errors, 5xx server errors)
+- Curl error codes
+- Authentication failures (certificate errors, OAuth token issues)
+- Pre-sign request failures
+- Network connectivity issues
+- Retry exhaustion
+
+### Configuration Parsing Errors
+```bash
+grep -n "dcm_parseconf\|parse\|ERROR\|Invalid" dcm.log.0
+cat /nvram/DCMresponse.txt  # Check configuration format
+```
+Verify:
+- JSON/XML syntax validity
+- Required fields present (URL, schedule)
+- Upload protocol configuration (HTTP, HTTPS)
+- Authentication settings
+
+### Cron Scheduling Issues
+```bash
+grep -n "dcm_cronparse\|cron\|schedule\|ERROR" dcm.log.0
+```
+Check:
+- Cron expression validity
+- Schedule parsing errors
+- Job execution timing
+- Missed schedule windows
+
+### RBUS Communication Errors
+```bash
+grep -n "rbus\|RBUS_ERROR\|connection\|method" dcm.log.0
+```
+Verify:
+- RBUS daemon (rtrouted) running
+- Method registration success
+- Event subscription success
+- Method invocation errors
+
+### Upload Strategy Issues
+```bash
+grep -n "strategy\|RRD\|OnDemand\|Reboot\|DCM\|Non-DCM" uploadstblogs.log.0
+```
+Identify:
+- Which strategy was selected
+- Strategy selection logic
+- Trigger conditions met/not met
+- Early abort conditions (privacy mode, no logs)
+
+### Archive/Packaging Failures
+```bash
+grep -n "archive\|tar\|gzip\|packaging\|collection" uploadstblogs.log.0
+```
+Check for:
+- Disk space issues
+- File permission errors
+- Tar/gzip failures
+- Log file collection errors
+
+---
+
+## Step 4: Correlate with Source Code
+
+Map log evidence to source files:
+
+| Issue Area | Source Files |
+|---|---|
+| Daemon initialization | `dcm.c`, `dcm_parseconf.c` |
+| RBUS interface | `dcm_rbus.c` |
+| Cron parsing | `dcm_cronparse.c` |
+| Job scheduling | `dcm_schedjob.c` |
+| Configuration parsing | `dcm_parseconf.c` |
+| uploadSTBLogs main logic | `uploadstblogs/src/uploadstblogs.c` |
+| Upload strategies | `uploadstblogs/src/strategy_*.c`, `uploadstblogs/src/strategy_selector.c` |
+| Upload engine | `uploadstblogs/src/upload_engine.c` |
+| Retry logic | `uploadstblogs/src/retry_logic.c` |
+| Archive management | `uploadstblogs/src/archive_manager.c` |
+| Authentication | `uploadstblogs/src/` (mTLS/OAuth handling) |
+| RBUS interface | `uploadstblogs/src/rbus_interface.c` |
+| On-demand upload | `uploadstblogs/src/uploadlogsnow.c` |
+
+### Example: Upload Failure Correlation
+
+If logs show:
+```
+ERROR: HTTP 403 Forbidden - pre-sign request failed
+ERROR: retry_logic: Max retries exhausted for Direct path
+```
+
+1. Check `uploadstblogs/src/upload_engine.c` for pre-sign logic
+2. Check `uploadstblogs/src/retry_logic.c` for retry configuration
+3. Verify authentication configuration in `/nvram/DCMresponse.txt`
+4. Check certificate paths and OAuth token generation
+
+---
+
+## Step 5: Reproduce Locally
+
+Create a minimal reproduction scenario:
+
+### For Configuration Issues
+```c
+// Test configuration parsing
+#include <assert.h>
+#include <stdio.h>
+#include <string.h>
+#include "dcm_parseconf.h"
+
+void test_parse_bad_config(void)
+{
+    DCMDHandle handle;
+    FILE *f;
+    int ret;
+
+    /* Initialize handle to a known state */
+    memset(&handle, 0, sizeof(handle));
+
+    /* Create test config with issue */
+    f = fopen("/tmp/test_dcmresponse.txt", "w");
+    if (f == NULL) {
+        perror("fopen failed");
+        return;
+    }
+
+    if (fprintf(f, "{invalid json}") < 0) {
+        perror("fprintf failed");
+        (void)fclose(f);
+        return;
+    }
+
+    if (fclose(f) != 0) {
+        perror("fclose failed");
+        return;
+    }
+
+    ret = dcmParseConfig(&handle, "/tmp/test_dcmresponse.txt");
+    /* Should fail gracefully */
+    assert(ret != 0);
+}
+```
+
+### For Upload Issues
+```bash
+# Test uploadSTBLogs manually
+export LOG_PATH=/opt/logs/
+export PERSISTENT_PATH=/opt/
+export DCM_FLAG=1
+export UploadOnReboot=1
+
+# Run with debug logging
+DEBUG=1 ./uploadstblogs 2>&1 | tee upload_debug.log
+```
+
+### For RBUS Issues
+```bash
+# Check RBUS daemon
+systemctl status rtrouted
+
+# Test RBUS method invocation
+rbuscli get Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Feature.DCM.Enable
+```
+
+---
+
+## Step 6: Test Gap Analysis
+
+Identify untested code paths that could harbor the bug:
+
+### Check Unit Test Coverage
+```bash
+# Generate coverage report
+./configure --enable-gcov
+make clean && make check
+gcov *.c
+```
+
+Look for:
+- Error path coverage in suspected functions
+- Configuration parsing edge cases
+- Network error handling
+- Retry logic branches
+- Strategy selection conditions
+
+### Check L2 Test Coverage
+Review `test/functional-tests/tests/` for:
+- Missing test scenarios matching the bug
+- Edge cases not covered
+- Error injection tests
+
+---
+
+## Step 7: Propose Fix and Test
+
+### Fix Template
+```c
+// BEFORE: Missing error check
+int ret = upload_to_s3(archive_path);
+// Continue without checking ret
+
+// AFTER: Proper error handling
+int ret = upload_to_s3(archive_path);
+if (ret != 0) {
+    DCM_LOG_ERROR("Upload failed: %d", ret);
+    // Trigger retry logic or fallback
+    return handle_upload_error(ret);
+}
+```
+
+### Test Template
+```cpp
+// Add unit test for the fix
+TEST(UploadEngineTest, HandleUploadFailureGracefully) {
+    // Mock upload failure
+    EXPECT_CALL(mockCurl, curl_easy_perform(_))
+        .WillOnce(Return(CURLE_COULDNT_CONNECT));
+    
+    int ret = upload_to_s3("test.tgz");
+    
+    // Verify error handling
+    EXPECT_NE(ret, 0);
+    // Verify cleanup happened
+    EXPECT_FALSE(file_exists("test.tgz"));
+}
+```

+
+---
+
+## Example Triage Flow
+
+**User:** "uploadSTBLogs keeps trying to upload but fails with HTTP 403"
+
+**Step 1:** Located `uploadstblogs.log.0`, found repeated:
+```
+2026-03-24 10:15:32 ERROR: Pre-sign request failed: HTTP 403 Forbidden
+2026-03-24 10:15:42 INFO: Retry attempt 2/5
+2026-03-24 10:15:52 ERROR: Pre-sign request failed: HTTP 403 Forbidden
+```
+
+**Step 2:** Checked `/nvram/DCMresponse.txt` — found OAuth token field empty
+
+**Step 3:** In `uploadstblogs/src/upload_engine.c`, pre-sign logic doesn't validate
+OAuth configuration before attempting request
+
+**Root Cause:** Missing validation of OAuth token before making pre-sign request
+
+**Fix:** Add validation in `prepare_upload_request()`:
+```c
+if (auth_type == AUTH_TYPE_OAUTH && !config->oauth_token) {
+    DCM_LOG_ERROR("OAuth token not configured");
+    return ERR_INVALID_CONFIG;
+}
+```
+
+**Test:** Add `TEST(UploadEngineTest, RejectMissingOAuthToken)`

+# DCM Agent
+
+The **DCM (Device Configuration Manager) Agent** is a lightweight C daemon for RDK-based embedded devices. It receives device configuration payloads from the Telemetry 2.0 (T2) subsystem via RBUS, parses DCM settings, and schedules periodic jobs such as log uploads and firmware update checks. The project also bundles sub-modules for STB log upload, log backup, and USB log transfer, all originally implemented as shell scripts and now ported to C for performance and portability.

+## Architecture
+
+The DCM Agent runs as a forked background daemon (`dcmd`). On startup it:
+
+1. Checks for duplicate instances via a PID file.
+2. Initialises the configuration parser, RBUS connection, and cron scheduler.
+3. Loads default boot configuration.
+4. Waits until T2 event subscription is confirmed.
+5. Sends a reload-config event to T2 and enters the main event loop.
+6. On receiving a `Device.DCM.Processconfig` event, parses the DCM settings file and starts/restarts the scheduled jobs.

+## Modules
+
+### dcm — Core Daemon
+
+| File | Role |
+|------|------|
+| `dcm.c` | Daemon entry point, init/uninit, main event loop |
+| `dcm.h` | `DCMDHandle` struct, public init/uninit declarations |
+
+**Key struct:**
+
+```c
+typedef struct _dcmdHandle {
+    BOOL  isDebugEnabled;
+    BOOL  isDCMRunning;
+    VOID *pRbusHandle;       /* DCMRBusHandle */
+    VOID *pDcmSetHandle;     /* DCMSettingsHandle */
+    VOID *pLogSchedHandle;   /* DCMScheduler for log upload */
+    VOID *pDifdSchedHandle;  /* DCMScheduler for FW update */
+    INT8 *pExecBuff;         /* 1 KB command buffer */
+    INT8  logCron[16];       /* Cron pattern for log upload */
+    INT8  difdCron[16];      /* Cron pattern for FW update */
+} DCMDHandle;
+```
+
+**Lifecycle:**
+
+```c
+INT32 dcmDaemonMainInit(DCMDHandle *pdcmHandle);
+VOID  dcmDaemonMainUnInit(DCMDHandle *pdcmHandle);
+```
+
+`dcmDaemonMainUnInit()` releases all sub-module resources in reverse order of acquisition.
+
+**Scheduled job names:**
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `DCM_LOGUPLOAD_SCHED` | `"DCM_LOG_UPLOAD"` | Periodic STB log upload |
+| `DCM_DIFD_SCHED` | `"DCM_FW_UPDATE"` | Firmware update check |
+
+---
+
+### dcm\_parseconf — Configuration Parser
+
+| File | Role |
+|------|------|
+| `dcm_parseconf.c` | Parses DCM JSON/key-value config files |
+| `dcm_parseconf.h` | `DCMSettingsHandle`, public API |
+
+Reads the DCM response file (typically `/tmp/DCMSettings.conf` or `/opt/.DCMSettings.conf`) and extracts the following settings:
+
+| JSON URN | Field | Description |
+|----------|-------|-------------|
+| `urn:settings:LogUploadSettings:UploadRepository:uploadProtocol` | Upload protocol | `HTTP` or `HTTPS` |
+| `urn:settings:LogUploadSettings:UploadRepository:URL` | Upload URL | Remote endpoint |
+| `urn:settings:LogUploadSettings:UploadOnReboot` | Reboot flag | Upload on reboot |
+| `urn:settings:LogUploadSettings:UploadSchedule:cron` | Log cron | Cron schedule string |
+| `urn:settings:CheckSchedule:cron` | FW update cron | Cron schedule string |
+| `urn:settings:TimeZoneMode` | Timezone | Device timezone |
+
+**Public API:**
+
+```c
+INT32  dcmSettingsInit(VOID **ppdcmSetHandle);
+VOID   dcmSettingsUnInit(VOID *pdcmSetHandle);
+INT32  dcmSettingParseConf(VOID *pdcmSetHandle, INT8 *pConffile,
+                           INT8 *pLogCron, INT8 *pDifdCron);
+INT8*  dcmSettingsGetUploadProtocol(VOID *pdcmSetHandle);
+INT8*  dcmSettingsGetUploadURL(VOID *pdcmSetHandle);
+INT8*  dcmSettingsGetRDKPath(VOID *pdcmSetHandle);
+INT32  dcmSettingsGetMMFlag();         /* Maintenance Manager check */
+INT32  dcmSettingDefaultBoot();        /* Load config at boot */
+```
+
+**Key internal buffers** (all statically sized, no dynamic allocation):
+
+| Field | Size | Purpose |
+|-------|------|---------|
+| `cJsonStr` | 2048 B | Raw JSON payload |
+| `cUploadURL` | 128 B | Upload endpoint |
+| `cUploadPrtl` | 8 B | Protocol string |
+| `cTimeZone` | 16 B | Timezone |
+| `cRdkPath` | 80 B | RDK library path |
+| `ctBuff` | 1024 B | Temporary command buffer |
+
+---
+
+### dcm\_rbus — RBUS Integration
+
+| File | Role |
+|------|------|
+| `dcm_rbus.c` | RBUS open/close, event subscription, event publishing |
+| `dcm_rbus.h` | `DCMRBusHandle`, event name constants, public API |
+
+Handles all communication with the RDK RBUS message bus and acts as the bridge between DCM and Telemetry 2.0.
+
+**RBUS events:**
+
+| Constant | Value | Direction |
+|----------|-------|-----------|
+| `DCM_RBUS_SETCONF_EVENT` | `Device.DCM.Setconfig` | T2 → DCM |
+| `DCM_RBUS_PROCCONF_EVENT` | `Device.DCM.Processconfig` | T2 → DCM |
+| `DCM_RBUS_RELOAD_EVENT` | `Device.X_RDKCENTREL-COM.Reloadconfig` | DCM → T2 |
+
+**RBUS data model parameters:**
+
+| Parameter | Purpose |
+|-----------|---------|
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Feature.Telemetry.Version` | T2 version query |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Feature.Telemetry.ConfigURL` | Config fetch URL |
+
+**Public API:**
+
+```c
+INT32  dcmRbusInit(VOID **ppDCMRbusHandle);
+INT32  dcmRbusSubscribeEvents(VOID *pDCMRbusHandle);
+VOID   dcmRbusUnInit(VOID *pDCMRbusHandle);
+INT32  dcmRbusSendEvent(VOID *pDCMRbusHandle);
+INT32  dcmRbusSchedJobStatus(VOID *pDCMRbusHandle);   /* Poll: config ready? */
+VOID   dcmRbusSchedResetStatus(VOID *pDCMRbusHandle); /* Reset after processing */
+INT8   dcmRbusGetEventSubStatus(VOID *pDCMRbusHandle);
+INT8*  dcmRbusGetConfPath(VOID *pDCMRbusHandle);
+INT32  dcmRbusGetT2Version(VOID *pDCMRbusHandle, VOID *value);
+```
+
+---
+
+### dcm\_schedjob — Cron Scheduler
+
+| File | Role |
+|------|------|
+| `dcm_schedjob.c` | Per-job scheduler threads driven by cron expressions |
+| `dcm_schedjob.h` | `DCMScheduler` struct, callback typedef, public API |
+
+One `DCMScheduler` instance is created per job. A dedicated POSIX thread (`dcmSchedulerThread`) sleeps until the next cron fire-time using `pthread_cond_timedwait`, then invokes the registered callback.
+
+**Scheduler struct:**
+
+```c
+typedef struct _dcmScheduler {
+    INT8           *name;
+    BOOL            terminated;
+    BOOL            startSched;
+    dcmCronExpr     parseData;    /* Pre-parsed cron expression */
+    pthread_t       tId;
+    pthread_mutex_t tMutex;
+    pthread_cond_t  tCond;
+    DCMSchedCB      pDcmCB;       /* Job callback */
+    VOID           *pUserData;    /* Caller context passed to callback */
+} DCMScheduler;
+```
+
+**Callback signature:**
+
+```c
+typedef VOID (*DCMSchedCB)(const INT8* profileName, VOID *pUsrData);
+```
+
+**Public API:**
+
+```c
+INT32  dcmSchedInit();
+VOID   dcmSchedUnInit();
+VOID*  dcmSchedAddJob(INT8 *pJobName, DCMSchedCB pDcmCB, VOID *pUsrData);
+VOID   dcmSchedRemoveJob(VOID *pHandle);
+INT32  dcmSchedStartJob(VOID *pHandle, INT8 *pCronPattern);
+INT32  dcmSchedStopJob(VOID *pHandle);
+```
+
+**Thread safety:** Each `DCMScheduler` has its own mutex and condition variable. The terminated flag is checked atomically under the lock to ensure clean shutdown.
+
+---
+
+### dcm\_cronparse — Cron Expression Parser
+
+| File | Role |
+|------|------|
+| `dcm_cronparse.c` | Tokenises and validates 6-field cron expressions |
+| `dcm_cronparse.h` | `dcmCronExpr` bitfield struct, public API |
+
+Supports standard 6-field cron syntax (seconds, minutes, hours, day-of-month, month, day-of-week). Results are stored as compact bitmask arrays with zero dynamic allocation.
+
+**Parsed struct:**
+
+```c
+typedef struct {
+    UINT8 seconds[8];       /* 60-bit bitmask */
+    UINT8 minutes[8];       /* 60-bit bitmask */
+    UINT8 hours[3];         /* 24-bit bitmask */
+    UINT8 days_of_week[1];  /*  7-bit bitmask */
+    UINT8 days_of_month[4]; /* 31-bit bitmask */
+    UINT8 months[2];        /* 12-bit bitmask */
+} dcmCronExpr;
+```
+
+**Public API:**
+
+```c
+INT32   dcmCronParseExp(const INT8* expression, dcmCronExpr* target);
+time_t  dcmCronParseGetNext(dcmCronExpr* expr, time_t date);
+```
+
+`dcmCronParseGetNext()` returns the next `time_t` after `date` at which the expression fires; the scheduler uses this to compute `pthread_cond_timedwait` timeouts.
+

+
+### dcm\_utils — Utilities
+
+| File | Role |
+|------|------|
+| `dcm_utils.c` | File checks, PID management, system command execution, logging init |
+| `dcm_utils.h` | Logging macros, path constants, error codes |
+
+**Logging macros** (resolve to `RDK_LOG` when `RDK_LOGGER_ENABLED`, otherwise `fprintf(stderr,...)`):
+
+| Macro | Level |
+|-------|-------|
+| `DCMError(...)` | Error |
+| `DCMWarn(...)` | Warning |
+| `DCMInfo(...)` | Info |
+| `DCMDebug(...)` | Debug |
+
+**Path constants:**
+
+| Constant | Value |
+|----------|-------|
+| `DCM_LIB_PATH` | `/lib/rdk` |
+| `DCM_PID_FILE` | `/tmp/.dcm-daemon.pid` |
+| `DEVICE_PROP_FILE` | `/etc/device.properties` |
+| `DCM_TMP_CONF` | `/tmp/DCMSettings.conf` |
+| `DCM_OPT_CONF` | `/opt/.DCMSettings.conf` |
+
+**Error codes:**
+
+| Code | Value | Meaning |
+|------|-------|---------|
+| `DCM_SUCCESS` | `0` | Operation successful |
+| `DCM_FAILURE` | `-1` | General failure |
+| `DCM_IARM_COMPLETE` | `0` | IARM event sent OK |
+| `DCM_IARM_ERROR` | `1` | IARM event failed |
+
+---
+
+### uploadstblogs — STB Log Upload Library
+
+| Directory | Role |
+|-----------|------|
+| `uploadstblogs/src/` | Compiled into `libuploadstblogs.la` |
+| `uploadstblogs/include/` | Public headers |
+
+Provides a single C API replacing the `uploadSTBLogs.sh` script family. The daemon links the library and calls `uploadstblogs_run()` on each log upload trigger. The current implementation enforces single-instance execution across processes via a file lock, but it is not re-entrant and is not safe for concurrent calls within the same process or from multiple threads.
+
+**Entry point:**
+
+```c
+UploadSTBLogsParams params = {
+    .flag             = 0,
+    .dcm_flag         = 1,
+    .upload_on_reboot = false,
+    .upload_protocol  = "HTTP",
+    .upload_http_link = "https://example.com/upload",
+    .trigger_type     = TRIGGER_SCHEDULED,
+    .rrd_flag         = false,
+    .rrd_file         = NULL
+};
+int result = uploadstblogs_run(&params);
+```

+| validation | `validation.h` | Parameter and path validation |
+| verification | `verification.h` | Post-upload result verification |
+

+
+### backup\_logs — Log Backup
+
+| Directory | Role |
+|-----------|------|
+| `backup_logs/src/` | Persistent log backup utility |
+| `backup_logs/include/` | Public headers |
+
+Replaces script-based log backup. Copies or archives critical log files to a backup location. Designed to preserve logs across reboots on constrained storage.
+
+**Entry point:**
+
+```c
+backup_config_t config;
+/* populate config... */
+int ret = backup_logs_init(&config);
+if (ret == BACKUP_SUCCESS) {
+    backup_logs_execute(&config);
+    backup_logs_cleanup(&config);
+}
+```
+
+**Key modules:**
+
+| Module | Header | Responsibility |
+|--------|--------|---------------|
+| backup\_engine | `backup_engine.h` | Core backup orchestration |
+| config\_manager | `config_manager.h` | Backup configuration coordination and validation |
+| special\_files | `special_files.h` | `special_files.conf` loading/parsing and file list management |
+| sys\_integration | `sys_integration.h` | systemd status/READY notification |
+
+Configuration file `special_files.conf` lists files to include in each backup run.

+
+### usbLogUpload — USB Log Upload
+
+| Directory | Role |
+|-----------|------|
+| `usbLogUpload/src/` | Log transfer to attached USB storage |
+| `usbLogUpload/include/` | Public headers |
+
+Replaces `usbLogUpload.sh`. Validates USB mount, discovers log files, compresses them, and copies to the USB device with a standard naming convention.
+
+**Key modules:**
+
+| Module | Responsibility |
+|--------|---------------|
+| usb\_log\_main | Entry point and workflow orchestration |
+| usb\_log\_validation | Device and mount-point validation |
+| usb\_log\_file\_manager | Log discovery and directory operations |

+    SchedLog -->|DCMSchedCB| Job[dcmRunJobs callback\non main data]
+    SchedFW  -->|DCMSchedCB| Job
+```
+
+| Thread | Created by | Purpose | Synchronisation |
+|--------|-----------|---------|-----------------|
+| Main daemon | OS / `fork()` | Init, event loop, config parsing | – |
+| RBUS callback | RBUS library | Receives T2 events | `DCMRBusHandle.schedJob` flag (int) |
+| Scheduler (per job) | `dcmSchedAddJob()` | Fires job callback at cron time | `pthread_mutex_t` + `pthread_cond_t` per `DCMScheduler` |
+
+**Lock ordering** — to avoid deadlocks if multiple scheduler jobs are ever accessed concurrently, always acquire job locks in creation order (log upload before FW update).
+
+**Signal handling** — `SIGINT`, `SIGTERM`, and `SIGABRT` route to `sig_handler()`, which calls `dcmDaemonMainUnInit()` and exits cleanly.
+
+---
+
+## Memory Management
+
+The daemon uses a minimal-allocation strategy suited to constrained devices:
+
+```mermaid
+graph TD
+    A[dcmDaemonMainInit] --> B[malloc DCMDHandle\n~200 bytes]
+    A --> C[malloc pExecBuff\n1024 bytes]
+    A --> D[dcmSettingsInit\nstack-only DCMSettingsHandle]
+    A --> E[dcmRbusInit\nmalloc DCMRBusHandle]
+    F[dcmDaemonMainUnInit] --> G[free pExecBuff]
+    F --> H[dcmSettingsUnInit]
+    F --> I[dcmRbusUnInit → free DCMRBusHandle]
+    F --> J[dcmSchedRemoveJob × 2]
+```
+
+**Ownership rules:**
+
+| Resource | Owner | Freed by |
+|----------|-------|---------|
+| `DCMDHandle` | `main()` | `main()` via `free()` |
+| `pExecBuff` | `DCMDHandle` | `dcmDaemonMainUnInit()` |
+| `DCMSettingsHandle` | `dcmSettingsInit()` | `dcmSettingsUnInit()` |
+| `DCMRBusHandle` | `dcmRbusInit()` | `dcmRbusUnInit()` |
+| `DCMScheduler` | `dcmSchedAddJob()` | `dcmSchedRemoveJob()` |
+
+**Static buffers** — `DCMSettingsHandle` uses only fixed-size fields; no dynamic allocation inside the parser.
+
+**Typical footprint:** < 8 KB total heap for the core daemon (excluding uploadstblogs and RBUS library allocations).
+
+---
+
+## Build Instructions
+
+### Prerequisites
+
+| Tool | Version |
+|------|---------|
+| GCC | 7+ (ARMv7 cross-compiler supported) |
+| Autotools | autoconf 2.69+, automake 1.15+ |
+| libtool | 2.4+ |
+| librbus | Platform-provided |
+| libcjson | 1.7+ |
+| librdkloggers | Optional (RDK logger) |
+| libIBus / libmaintenanceMgr | Optional (Maintenance Manager) |
+
+### Build Steps
+
+```bash
+# Generate build system
+autoreconf -i
+
+# Configure (native)
+./configure
+
+# Configure (cross-compile for RDK target)
+./configure --host=arm-linux-gnueabihf \
+            --with-sysroot=/path/to/sysroot
+
+# Build
+make
+
+# Install
+make install
+```
+
+### Conditional Compile Flags
+
+| Flag | Effect |
+|------|--------|
+| `-DRDK_LOGGER_ENABLED` | Use RDK logger instead of stderr |
+| `-DHAS_MAINTENANCE_MANAGER` | Enable Maintenance Manager integration via IARM |
+| `-DGTEST_ENABLE` | Stub out RBUS/IARM for unit testing |
+| `-DDCM_DEF_LOG_URL=<url>` | Override default fallback upload URL |
+| `-DDCM_LOG_TFTP=<name>` | Override TFTP log upload identifier |
+
+---
+
+## Unit Testing
+
+Unit tests use **Google Test** and **Google Mock** and reside in:
+
+| Directory | Covers |
+|-----------|--------|
+| `unittest/` | `dcm`, `dcm_parseconf`, `dcm_rbus`, `dcm_schedjob`, `dcm_cronparse`, `dcm_utils` |
+| `uploadstblogs/unittest/` | All `uploadstblogs` sub-modules |
+| `backup_logs/unittest/` | All `backup_logs` sub-modules |
+| `unittest/mocks/` | `mockrbus.cpp/.h` — RBUS mock |
+
+### Running Unit Tests
+
+Tests are executed in a Docker container using the standard RDK CI image:
+
+```bash
+# Pull the CI container
+docker pull ghcr.io/rdkcentral/docker-rdk-ci:latest
+
+# Run tests inside container
+docker run --rm -v "$(pwd):/workspace" \
+  ghcr.io/rdkcentral/docker-rdk-ci:latest \
+  bash /workspace/unit_test.sh
+```
+
+### Coverage Target
+
+Aim for **≥ 80%** line coverage. Each test file exercises:
+- Normal operation paths
+- NULL / invalid parameter paths
+- Boundary values for cron expressions and buffer sizes
+- Error injection for RBUS and file I/O failures
+
+---
+
+## Error Handling
+
+All functions return `DCM_SUCCESS` (`0`) on success or `DCM_FAILURE` (`-1`) on error, consistent with the `dcm_types.h` convention. Pointer-returning functions return `NULL` on failure.
+
+**Logging convention:**
+
+```c
+if (ret != DCM_SUCCESS) {
+    DCMError("Descriptive message with context: %d\n", ret);
+    goto cleanup;  /* single exit point pattern */
+}
+```
+
+**Signal-driven shutdown** — the daemon sends an IARM `DCM_IARM_ERROR` maintenance event before exiting on fatal signals, allowing the platform maintenance manager to take corrective action.
+
+---
+
+## Configuration Files
+
+| File | Location | Purpose |
+|------|----------|---------|
+| `DCMSettings.conf` | `/tmp/` or `/opt/` | DCM payload from T2 (JSON + key-value) |
+| `device.properties` | `/etc/device.properties` | Device model, MAC, and RDK path |
+| `telemetry2_0.properties` | `/etc/telemetry2_0.properties` | T2 feature flags |
+| `include.properties` | `/etc/include.properties` | Additional properties include |
+| `rdk_maintenance.conf` | `/opt/rdk_maintenance.conf` | Maintenance Manager schedule |
+| `special_files.conf` | `/etc/backup_logs/` | List of files to back up |
+| `debug.ini` | `/etc/debug.ini` | RDK logger level configuration |
+| `.dcm-daemon.pid` | `/tmp/` | Running daemon PID |
+
+---
+
+## Platform Notes
+
+### Linux / RDK Embedded
+
+- Requires POSIX pthreads.
+- RBUS IPC (`librbus`) must be available at runtime.
+- Optional IARM bus integration for Maintenance Manager notifications.
+- RDK logger (`librdkloggers`) replaces `fprintf(stderr)` when available.
+
+### Resource Constraints
+
+| Resource | Typical Budget |
+|----------|---------------|
+| Heap (core daemon) | < 8 KB |
+| Heap (uploadstblogs in progress) | < 64 KB (transient) |
+| Stack per scheduler thread | Default (8 KB minimum) |
+| Binary size (`dcmd`) | < 256 KB stripped |
+
+### Cross-Compilation
+
+The build system fully supports cross-compilation via `--host=` and `--with-sysroot=`. All library paths use `PKG_CONFIG_SYSROOT_DIR` to locate target headers.
+

+## 3. Data Structures
+
+### 3.1 Core Data Structures
+
+```c
+typedef struct {
+    char log_path[PATH_MAX];
+    char prev_log_path[PATH_MAX];
+    char prev_log_backup_path[PATH_MAX];
+    char persistent_path[PATH_MAX];
+    bool hdd_enabled;
+} backup_config_t;
+
+typedef enum {
+    BACKUP_OP_MOVE,
+    BACKUP_OP_COPY,
+    BACKUP_OP_DELETE
+} backup_operation_type_t;
+
+typedef struct {
+    char source_path[PATH_MAX];
+    char dest_path[PATH_MAX];
+    backup_operation_type_t operation;
+    char source_extension[32];
+    char dest_extension[32];
+} backup_operation_t;
+typedef struct {
+    int error_code;
+    char error_message[256];
+    const char* function_name;
+    int line_number;
+} error_info_t;
+```
+
+### 3.3 Special Files Configuration
+
+#### 3.3.1 Special Files Data Structure
+```c
+typedef enum {
+    SPECIAL_FILE_COPY = 0,  // cp operation
+    SPECIAL_FILE_MOVE = 1   // mv operation
+} special_file_operation_t;
+
+typedef struct {
+    char source_path[PATH_MAX];
+    char destination_path[PATH_MAX];
+    special_file_operation_t operation;
+    char conditional_check[64];  // Optional condition variable name
+} special_file_entry_t;
+
+typedef struct {
+    special_file_entry_t entries[MAX_SPECIAL_FILES];
+    size_t count;
+    bool config_loaded;
+} special_files_config_t;
+
+#define MAX_SPECIAL_FILES 32  // Maximum number of special files to handle
+```
+
+### 3.2 Memory Management Strategy
+- Use fixed-size buffers to avoid dynamic allocation
+- Implement memory pools for temporary operations
+- Stack-based allocation for small, short-lived data
+- Pre-allocated arrays for file lists and paths
+
+#### 3.3.2 Special Files Configuration Format
+The special files configuration follows a simple one-filename-per-line format for embedded system efficiency:
+```properties
+# Special Files Configuration for backup_logs
+# Format: One source file path per line
+# Comments start with # and empty lines are ignored
+# 
+# Operation determination is handled by the implementation:
+#   - Files in /tmp are typically moved (mv operation)
+#   - Configuration and version files are typically copied (cp operation)
+#   - Destination is automatically determined based on source filename
+
+# Files from /tmp directory (will be moved)
+/tmp/disk_cleanup.log
+/tmp/mount_log.txt
+/tmp/mount-ta_log.txt
+
+# Files from /etc directory (will be copied)
+/etc/skyversion.txt
+/etc/rippleversion.txt
+
+# Version file from root (will be copied)
+/version.txt
+```
+
+## 3.4 Special Files Configuration Management
+
+### 3.4.1 Configuration Loading
+The special files configuration is loaded from `/etc/special_files.properties` using a simple line-based parser that:
+- Supports one filename per line format with comments (lines starting with #)
+- Automatically determines operation type based on source file location
+- Automatically determines destination filename from source pathname
+- Uses LOG_PATH from backup configuration for destination directory
+- Provides error reporting for missing or invalid files
+
+### 3.4.2 Configuration Processing
+- Files in `/tmp/` directory are moved (mv operation) to preserve space
+- Configuration and version files are copied (cp operation) to preserve originals
+- Destination directory is automatically set to the configured LOG_PATH
+- Destination filename is extracted from the source file path
+- Log warnings for entries with non-existent source files but continue processing
+
+## 4. Module Interfaces
+
+### 4.1 Configuration Manager Interface
+```c
+int config_load(backup_config_t* config);
+int config_validate(const backup_config_t* config);
+const char* config_get_log_path(void);
+bool config_is_hdd_enabled(void);
+
+// Special files configuration interface
+int special_files_load_config(special_files_config_t* config, const char* config_file);
+int special_files_validate_entry(const special_file_entry_t* entry);
+int special_files_execute_entry(const special_file_entry_t* entry, 
+                               const backup_config_t* backup_config);
+int special_files_execute_all(const special_files_config_t* config, 
+                             const backup_config_t* backup_config);
+void special_files_cleanup(void);
+```
+
+### 4.2 Directory Manager Interface
+```c
+// Implemented using RDK system utilities
+int createDir(char* path);           // Create directory if not exists
+int emptyFolder(char* path);         // Clean directory contents
+int filePresentCheck(const char* path); // Check if file/directory exists
+int removeFile(const char* path);    // Remove file or directory
+```
+
+### 4.3 Log Backup Engine Interface
+```c
+int backup_execute_hdd_enabled_strategy(const backup_config_t* config);
+int backup_execute_hdd_disabled_strategy(const backup_config_t* config);
+int backup_execute_common_operations(const backup_config_t* config);
+int move_log_files_by_pattern(const char* source_dir, const char* dest_dir);
+```
+
+### 4.4 File Operations Interface
+```c
+// Implemented using RDK system utilities
+int copyFiles(const char* source, const char* dest);  // Copy file operation
+int removeFile(const char* path);                     // Remove file operation
+int filePresentCheck(const char* path);               // Check file existence
+// Move is implemented as copy + remove sequence
+```
+
+## 5. Data Flow
+
+### 5.1 Main Execution Flow (As Implemented)
+1. **Initialization Phase**
+   - Initialize RDK logging system with extended configuration
+   - Load system configuration from RDK property APIs (`getIncludePropertyData`, `getDevicePropertyData`)
+   - Create required directories: LOG_PATH, PREV_LOG_PATH, PREV_LOG_BACKUP_PATH
+   - Clean PREV_LOG_BACKUP_PATH directory
+   - Create persistent file marker (`logFileBackup`)
+   - Run disk threshold check script if available
+
+2. **Pre-Execution Phase**
+   - Find and remove existing `last_reboot` marker files
+   - Determine backup strategy based on HDD_ENABLED configuration
+
+3. **Backup Execution Phase**
+   - Execute appropriate backup strategy (HDD-enabled or HDD-disabled)
+   - Move log files using pattern matching (*.txt*, *.log*, bootlog)
+   - Handle log rotation for HDD-disabled devices
+
+4. **Common Operations Phase**
+   - Execute special files operations based on configuration
+   - Copy system version files (skyversion.txt, rippleversion.txt, version.txt)
+   - Create new `last_reboot` marker file
+   - Send systemd notification if available
+
+5. **Cleanup Phase**
+   - Cleanup special files manager resources
+   - Release all allocated resources
+   - Report final execution status
+
+### 5.2 Error Handling Flow
+- Centralized error handling through error_info_t structure
+- Error propagation through return codes
+- Logging of all error conditions with context
+- Graceful degradation on non-critical failures
+
+### 5.3 Visual Flow Representation
+
+The system workflow is represented through detailed diagrams stored in the [diagrams directory](diagrams/backup_logs_flowcharts.md). This includes both Mermaid-format diagrams and text-based alternatives for environments with limited diagram rendering capabilities.
+
+#### 5.3.1 Main Backup Process Flow
+The primary execution flow showing the complete backup process from initialization to completion, including decision points for HDD-enabled vs HDD-disabled devices. Available in both Mermaid and text formats.
+
+#### 5.3.2 Component Interaction Sequence
+A detailed sequence diagram illustrating the interactions between all system components, showing the order of operations and data flow between modules. Includes timing annotations and error paths.
+
+#### 5.3.3 HDD Disabled Strategy Detail
+A specialized flowchart focusing on the complex log rotation logic for HDD-disabled devices, showing the 4-level backup rotation mechanism with all decision points clearly marked.
+
+#### 5.3.4 Error Handling and Recovery Flow
+A comprehensive error handling flowchart showing how different types of errors are categorized, handled, and recovered from in the system. Includes recovery strategies and escalation paths.
+
+## 6. Key Algorithms
+
+### 6.1 HDD-Disabled Backup Algorithm
+```
+1. Check for existing backup levels (messages.txt, bak1_messages.txt, etc.)
+2. If no existing backups:
+   - Move all logs to PreviousLogs
+3. If backup level 1 exists but not level 2:
+   - Move current logs to PreviousLogs with bak1_ prefix
+4. If backup levels 1-2 exist but not level 3:
+   - Move current logs to PreviousLogs with bak2_ prefix
+5. If all backup levels exist:
+   - Rotate: bak1->root, bak2->bak1, bak3->bak2, current->bak3
+6. Create last_reboot marker file
+```
+
+### 6.2 HDD-Enabled Backup Algorithm
+```
+1. If no messages.txt in PreviousLogs:
+   - Move all logs to PreviousLogs
+   - Create last_reboot marker
+2. If messages.txt exists:
+   - Remove existing last_reboot markers
+   - Create timestamped backup directory
+   - Move current logs to timestamped directory
+   - Create last_reboot marker in timestamped directory
+```
+
+### 6.3 File Pattern Matching Algorithm
+- Use POSIX-compliant pattern matching
+- Support for wildcard patterns (*.txt, *.log, etc.)
+- Efficient directory traversal with depth control
+- Filter by file type (regular files vs. symbolic links)
+
+### 6.5 Special Files Processing Algorithm
+```
+1. Load special files configuration from /etc/special_files.properties
+2. Parse each line as a single source file path
+3. Skip comment lines (starting with #) and empty lines
+4. For each special file entry:
+   a. Check if source file exists (log warning if not found, continue)
+   b. Determine operation based on source path:
+      - Files in /tmp/: move operation (copy + delete)
+      - All other files: copy operation
+   c. Extract filename from source path for destination
+   d. Build full destination path using ${LOG_PATH}/filename
+   e. Verify destination directory exists, create if needed
+   f. Execute operation (copy or move) based on determination
+   g. Log operation result and any errors
+5. Update operation statistics and cleanup resources
+```
+
+### 6.6 Special Files Configuration Parser Algorithm
+```
+1. Open /etc/special_files.properties file
+2. For each line:
+   a. Skip empty lines and comments (lines starting with #)
+   b. Trim whitespace and newline characters
+   c. Store entire line as source_path in special_file_entry_t structure
+   d. Extract filename from source path for destination_path
+   e. Set default operation to SPECIAL_FILE_COPY (will be determined at execution)
+   f. Set conditional_check to empty string
+3. Return parsed configuration with entry count or error code
+```
+
+# Additional Data Structures
+
+### 3.5 Enhanced Error Handling and Configuration Flags
+
+```c
+/* Complete error code enumeration */
+typedef enum {
+    BACKUP_SUCCESS = 0,
+    BACKUP_ERROR_CONFIG = -1,
+    BACKUP_ERROR_FILESYSTEM = -2,
+    BACKUP_ERROR_PERMISSIONS = -3,
+    BACKUP_ERROR_MEMORY = -4,
+    BACKUP_ERROR_INVALID_PARAM = -5,
+    BACKUP_ERROR_NOT_FOUND = -6,
+    BACKUP_ERROR_DISK_FULL = -7,
+    BACKUP_ERROR_SYSTEM = -8
+} backup_result_t;
+
+/* Configuration flags for advanced options */
+typedef struct {
+    bool debug_enabled;
+    bool force_rotation;
+    bool skip_disk_check;
+    bool cleanup_enabled;
+} backup_flags_t;
+
+/* Additional constants */
+#define MAX_ERROR_MESSAGE_LEN 256
+#define MAX_FUNCTION_NAME_LEN 64
+#define MAX_DESCRIPTION_LEN 128
+#define MAX_CONDITIONAL_LEN 64
+#define LOG_BACKUP_LOGS "LOG.RDK.BACKUPLOGS"
+```
+The special files processing is integrated into the main backup flow as follows:
+- **Phase 1**: Load special files configuration during initialization
+- **Phase 2**: Execute special file copy operations before log backup
+- **Phase 3**: Execute special file move operations during cleanup phase
+- **Phase 4**: Report special files operation status in final logging
+
+## 7. Threading and Concurrency
+
+### 7.1 Threading Strategy
+- Single-threaded design for simplicity and reliability
+- Thread-safe utility functions for potential future extensions
+- Use of atomic operations for shared state (if any)
+
+### 7.2 Synchronization
+- File locking for critical operations
+- Mutex protection for shared resources (if threading is added later)
+- Process-level coordination through lockfiles
+
+## 8. Performance Considerations
+
+### 8.1 Memory Optimization
+- Fixed-size buffers with compile-time sizing
+- Stack allocation preference over heap allocation
+- Minimal memory fragmentation through planned allocation patterns
+- Efficient string handling with bounded operations
+
+### 8.2 I/O Optimization
+- Batch file operations where possible
+- Minimize system calls through buffered operations
+- Efficient directory traversal algorithms
+- Streaming operations for large files
+
+## 8.5 RDK Logger Integration
+
+The implementation includes comprehensive RDK logging framework integration:
+
+### 8.5.1 Logger Configuration
+```c
+#ifdef RDK_LOGGER_EXT
+    rdk_logger_ext_config_t logger_config = {
+        .pModuleName = "LOG.RDK.BACKUPLOGS",
+        .loglevel = RDK_LOG_INFO,
+        .output = RDKLOG_OUTPUT_CONSOLE,
+        .format = RDKLOG_FORMAT_WITH_TS,
+        .pFilePolicy = NULL
+    };
+    rdk_logger_ext_init(&logger_config);
+#endif
+```
+
+### 8.5.2 Logger Features
+- **Extended Logger Support**: Uses RDK_LOGGER_EXT for enhanced configuration
+- **Timestamped Output**: All log messages include timestamps
+- **Console Fallback**: Graceful handling when logger initialization fails
+- **Debug INI Integration**: Reads configuration from `/etc/debug.ini`
+- **Module-Specific Logging**: Uses dedicated "LOG.RDK.BACKUPLOGS" component
+
+### 8.5.3 Build-time Configuration
+```c
+#ifdef RDK_LOGGER_EXT
+#define RDK_LOGGER_ENABLED
+#endif
+```
+
+The system supports both basic RDK logger and extended RDK logger configurations through compile-time flags.

+# backup\_logs Module
+
+## Overview
+
+`backup_logs` is a standalone C utility that migrates the functionality of `backup_logs.sh` to a compiled binary for RDK-based embedded devices. It preserves device log files across reboots by rotating them into a structured backup hierarchy (`PreviousLogs`/`PreviousLogs_backup`), supporting both HDD-enabled (timestamped directories) and HDD-disabled (4-level prefixed rotation) device configurations. The module also handles version file capture, special file processing, disk threshold checks, and systemd integration.

+## Architecture
+
+The module is a single executable (`backup_logs`) built from five C source files. It follows a strictly sequential, single-threaded execution model with no dynamic memory allocation beyond what is provided by the RDK utility layer.

+## Modules
+
+### backup\_logs — Entry Point
+
+| File | Role |
+|------|------|
+| `src/backup_logs.c` | Main entry point, top-level lifecycle orchestration |
+| `include/backup_logs.h` | Public API: `backup_logs_main()`, `backup_logs_init()`, `backup_logs_execute()`, `backup_logs_cleanup()` |
+
+Performs initialization of the RDK logger (with optional extended file-output configuration), loads configuration, drives the backup strategies in sequence, and ensures resources are released on all exit paths.
+
+**Top-level API:**
+
+```c
+int backup_logs_main(int argc, char *argv[]);
+int backup_logs_init(backup_config_t *config);
+int backup_logs_execute(const backup_config_t *config);
+int backup_logs_cleanup(backup_config_t *config);
+```
+
+**Logger initialization** (two modes, selected at compile-time):
+
+| Mode | Flag | Output | Notes |
+|------|------|--------|-------|
+| Extended | `-DRDK_LOGGER_EXT` | `/tmp/backup_logs.log` (50 KB, 5 rotations) | Timestamped, preferred on production |
+| Standard | `-DRDK_LOGGER_ENABLED` | Controlled by `/etc/debug.ini` | Fallback |
+| None | Neither flag | `stdout`/`stderr` | Development/CI only |
+
+---
+
+### config\_manager — Configuration
+
+| File | Role |
+|------|------|
+| `src/config_manager.c` | Reads RDK property system, constructs and validates all paths |
+| `include/config_manager.h` | `config_load()`, `special_files_config_load()`, `special_files_execute_operations()` |
+
+Uses the `libfwutils` APIs `getIncludePropertyData()` and `getDevicePropertyData()` to resolve the following properties:
+
+| Property | Source | Default |
+|----------|--------|---------|
+| `LOG_PATH` | `include.properties` | `/opt/logs` |
+| `HDD_ENABLED` | `device.properties` | `false` |
+| `APP_PERSISTENT_PATH` | `device.properties` | `/opt` |
+
+Derived paths are assembled in-struct (no heap allocation):
+
+```
+log_path            → LOG_PATH (e.g. /opt/logs)
+prev_log_path       → LOG_PATH/PreviousLogs
+prev_log_backup_path→ LOG_PATH/PreviousLogs_backup
+persistent_path     → APP_PERSISTENT_PATH
+```
+
+All `snprintf()` return values are checked and an error is returned if truncation would occur.
+
+**Public API:**
+
+```c
+int config_load(backup_config_t* config);
+int special_files_config_load(special_files_config_t* config,
+                              const char* config_file);
+int special_files_config_validate(const special_files_config_t* config);
+void special_files_config_free(special_files_config_t* config);
+int special_files_execute_operations(const special_files_config_t* config,
+                                    const backup_config_t* backup_config);
+int config_parse_environment(backup_config_t* config);
+```
+
+---
+
+### backup\_engine — Core Backup Logic
+
+| File | Role |
+|------|------|
+| `src/backup_engine.c` | Implements both backup strategies, file move/copy helpers |
+| `include/backup_engine.h` | Strategy and helper function declarations |
+
+The engine selects the appropriate strategy from `hdd_enabled` in `backup_config_t` and delegates through two well-defined strategy functions. File discovery uses `opendir`/`readdir` with `fnmatch`-style pattern matching against `*.txt*`, `*.log*`, and `bootlog`.
+
+**Public API:**
+
+```c
+int backup_execute_hdd_enabled_strategy(const backup_config_t* config);
+int backup_execute_hdd_disabled_strategy(const backup_config_t* config);
+int backup_execute_common_operations(const backup_config_t* config);
+int backup_and_recover_logs(const char* source, const char* dest,
+                            backup_operation_type_t op,
+                            const char* s_ext, const char* d_ext);
+int move_log_files_by_pattern(const char* source_dir, const char* dest_dir);
+```
+
+---
+
+### special\_files — Special File Processing
+
+| File | Role |
+|------|------|
+| `src/special_files.c` | Parses `/etc/backup_logs/special_files.conf`, executes move/copy per entry |
+| `include/special_files.h` | Init, load, validate, execute declarations |
+
+The configuration file format is one source path per line. Comments (`#`) and blank lines are skipped. The operation type is determined automatically from the source path prefix: files under `/tmp/` are **moved**; all others are **copied** to `LOG_PATH`.
+
+**Public API:**
+
+```c
+int  special_files_init(void);
+void special_files_cleanup(void);
+int  special_files_load_config(special_files_config_t* config,
+                               const char* config_file);
+int  special_files_validate_entry(const special_file_entry_t* entry);
+int  special_files_execute_entry(const special_file_entry_t* entry,
+                                const backup_config_t* backup_config);
+int  special_files_execute_all(const special_files_config_t* config,
+                               const backup_config_t* backup_config);
+```
+
+---
+
+### sys\_integration — Systemd Integration
+
+| File | Role |
+|------|------|
+| `src/sys_integration.c` | Sends `sd_notify` messages for service readiness and status |
+| `include/sys_integration.h` | `sys_send_systemd_notification()` |
+
+Wraps `libsystemd` to send `READY=1` and `STATUS=Logs Backup Done..!` at completion. Runs gracefully in non-systemd environments (notification errors are logged but do not fail the backup).
+
+```c
+int sys_send_systemd_notification(const char* message);
+```
+
+---
+
+## Data Structures and Types
+
+All types are defined in `include/backup_types.h`.
+
+### `backup_config_t`
+
+Central configuration structure passed through the entire call chain.
+
+```c
+typedef struct {
+    char log_path[PATH_MAX];            /* Primary log directory */
+    char prev_log_path[PATH_MAX];       /* LOG_PATH/PreviousLogs */
+    char prev_log_backup_path[PATH_MAX];/* LOG_PATH/PreviousLogs_backup */

+    bool hdd_enabled;                   /* Device has HDD */
+} backup_config_t;
+```
+
+### `backup_result_t` — Return Codes
+
+| Code | Value | Meaning |
+|------|-------|---------|
+| `BACKUP_SUCCESS` | `0` | Operation completed successfully |
+| `BACKUP_ERROR_CONFIG` | `-1` | Invalid or missing configuration (e.g. path truncation) |
+| `BACKUP_ERROR_FILESYSTEM` | `-2` | Directory or file operation failure |
+| `BACKUP_ERROR_PERMISSIONS` | `-3` | Insufficient filesystem permissions |
+| `BACKUP_ERROR_MEMORY` | `-4` | Memory allocation failure |
+| `BACKUP_ERROR_INVALID_PARAM` | `-5` | NULL or invalid function argument |

+
+### `backup_operation_type_t`
+
+```c
+typedef enum {
+    BACKUP_OP_MOVE,
+    BACKUP_OP_COPY,
+    BACKUP_OP_DELETE
+} backup_operation_type_t;
+```
+
+### `special_file_entry_t` / `special_files_config_t`
+
+```c
+typedef enum {
+    SPECIAL_FILE_COPY = 0,
+    SPECIAL_FILE_MOVE = 1
+} special_file_operation_t;
+
+typedef struct {
+    char source_path[PATH_MAX];

+} special_file_entry_t;
+
+typedef struct {
+    special_file_entry_t entries[MAX_SPECIAL_FILES]; /* MAX_SPECIAL_FILES = 32 */
+    size_t count;
+    bool config_loaded;
+} special_files_config_t;
+```
+
+### `backup_flags_t`
+
+```c
+typedef struct {
+    bool debug_enabled;
+    bool force_rotation;
+    bool skip_disk_check;
+    bool cleanup_enabled;
+} backup_flags_t;
+```
+
+---
+
+## Backup Strategies
+
+### HDD-Disabled: 4-Level Rotation
+
+Used on devices without persistent disk (`hdd_enabled = false`). The current backup level is detected by probing for `messages.txt`, `bak1_messages.txt`, `bak2_messages.txt`, and `bak3_messages.txt` in `PreviousLogs`.
+
+```mermaid
+stateDiagram-v2
+    [*] --> Level0 : No messages.txt
+    Level0 --> Level1 : After rotation\n(bak1_ prefix added)
+    Level1 --> Level2 : After rotation\n(bak2_ prefix added)
+    Level2 --> Level3 : After rotation\n(bak3_ prefix added)
+    Level3 --> Level0 : Full rotation:\nbak1→base, bak2→bak1,\nbak3→bak2, current→bak3
+```
+
+**Rotation cascade at Level 3:**
+
+| Step | Action |
+|------|--------|
+| 1 | `bak1_*` → rename without prefix (becomes base) |
+| 2 | `bak2_*` → rename with `bak1_` prefix |
+| 3 | `bak3_*` → rename with `bak2_` prefix |
+| 4 | Current logs → `PreviousLogs/bak3_<filename>` |
+
+File patterns matched: `*.txt*`, `*.log*`, `*.bin*`, `bootlog`
+
+### HDD-Enabled: Timestamped Directories
+
+Used on devices with persistent storage (`hdd_enabled = true`).
+
+```mermaid
+flowchart TD
+    A[Check for messages.txt\nin PreviousLogs]

+File patterns matched: `*.txt*`, `*.log*`, `bootlog` (no `.bin*` files)
+
+### Common Operations (both strategies)
+
+After the device-specific strategy completes, `backup_execute_common_operations()` runs:
+
+1. Loads and processes `/etc/backup_logs/special_files.conf`
+2. Copies version files: `/version.txt`, `/etc/skyversion.txt`, `/etc/rippleversion.txt`
+3. Removes old `last_reboot` markers
+4. Creates new `last_reboot` marker at `persistent_path/logFileBackup`
+5. Sends systemd `READY=1` + status notification

+
+## API Reference
+
+### `backup_logs_init()`
+
+Initialises the RDK logger and loads configuration from the RDK property system.
+
+**Signature:**
+```c
+int backup_logs_init(backup_config_t *config);
+```
+
+**Parameters:**
+- `config` — Pre-allocated `backup_config_t`; populated on return (must be non-NULL)
+
+**Returns:** `BACKUP_SUCCESS`, `BACKUP_ERROR_INVALID_PARAM`, or `BACKUP_ERROR_CONFIG`
+
+**Thread Safety:** Not thread-safe. Call once from the main thread.
+
+**Example:**
+```c
+backup_config_t config;
+memset(&config, 0, sizeof(config));
+int ret = backup_logs_init(&config);
+if (ret != BACKUP_SUCCESS) {
+    /* logger has already been called with the reason */
+    return ret;
+}
+```
+
+---
+
+### `backup_logs_execute()`
+
+Runs the complete backup workflow: workspace setup, strategy selection, common operations.
+
+**Signature:**
+```c
+int backup_logs_execute(const backup_config_t *config);
+```
+
+**Parameters:**
+- `config` — Populated configuration (from `backup_logs_init()`)
+
+**Returns:** `BACKUP_SUCCESS` or error code from the first failing step
+
+**Notes:**
+- A failure in disk threshold check is logged but does not abort execution.
+- Special file failures are non-fatal; execution continues with remaining entries.
+
+---
+
+### `backup_logs_cleanup()`
+
+Releases any resources acquired during execution and resets configuration.
+
+**Signature:**
+```c
+int backup_logs_cleanup(backup_config_t *config);
+```
+
+---
+
+### `config_load()`
+
+Resolves all configuration from the RDK property system and constructs derived paths.
+
+**Signature:**
+```c
+int config_load(backup_config_t* config);
+```
+
+**Returns:** `BACKUP_SUCCESS`, `BACKUP_ERROR_INVALID_PARAM`, or `BACKUP_ERROR_CONFIG` (path truncation)
+
+---
+
+### `backup_execute_hdd_enabled_strategy()`
+
+Implements the timestamped-directory backup for HDD-capable devices.
+
+**Signature:**
+```c
+int backup_execute_hdd_enabled_strategy(const backup_config_t* config);
+```
+
+---
+
+### `backup_execute_hdd_disabled_strategy()`
+
+Implements the 4-level prefixed rotation for non-HDD devices.
+
+**Signature:**
+```c
+int backup_execute_hdd_disabled_strategy(const backup_config_t* config);
+```
+
+---
+
+### `move_log_files_by_pattern()`
+
+Moves all files matching `*.txt*`, `*.log*`, or `bootlog` from source to destination directory.
+
+**Signature:**
+```c
+int move_log_files_by_pattern(const char* source_dir, const char* dest_dir);
+```
+
+**Returns:** `BACKUP_SUCCESS` or `BACKUP_ERROR_FILESYSTEM` if source cannot be opened
+
+**Notes:**
+- Each `snprintf()` building the full path is bounds-checked; oversized names are skipped with a log warning.
+- Uses `filePresentCheck()` to verify each candidate is a regular file.
+
+---
+
+### `special_files_execute_all()`
+
+Processes all entries in the special files configuration, executing move or copy per entry.
+
+**Signature:**
+```c
+int special_files_execute_all(const special_files_config_t* config,
+                              const backup_config_t* backup_config);
+```
+
+**Returns:** `BACKUP_SUCCESS`; individual entry failures are logged and skipped (non-fatal).
+
+---
+
+### `sys_send_systemd_notification()`
+
+Sends a notification string to the systemd service manager.
+
+**Signature:**
+```c
+int sys_send_systemd_notification(const char* message);
+```
+
+**Typical calls:**
+```c
+sys_send_systemd_notification("Logs Backup Done..!");
+```
+
+---
+
+## Special Files Configuration
+
+`/etc/backup_logs/special_files.conf` lists additional files to capture during the common operations phase. The format is one absolute source path per line.
+
+```conf
+# Special Files Configuration for backup_logs
+# Lines starting with # are comments; blank lines are ignored.
+#
+# Operation is determined automatically:
+#   /tmp/* → moved  (frees space)
+#   other  → copied (preserves original)
+# Destination is always LOG_PATH/<basename>
+
+/tmp/disk_cleanup.log
+/tmp/mount_log.txt
+/tmp/mount-ta_log.txt
+/etc/skyversion.txt
+/etc/rippleversion.txt
+/version.txt
+```
+
+**Processing rules:**
+
+| Source prefix | Operation | Destination |
+|---------------|-----------|-------------|
+| `/tmp/` | `move` (frees flash) | `LOG_PATH/<basename>` |
+| Other | `copy` (preserves src) | `LOG_PATH/<basename>` |
+
+The maximum configurable entries is `MAX_SPECIAL_FILES` (32). Missing source files generate a warning log entry but do not abort the backup.
+
+---
+
+## Error Handling
+
+All functions return `BACKUP_SUCCESS` (`0`) on success or a negative `backup_result_t` value on failure. The convention in every module is:
+
+```c
+if (!config) {
+    RDK_LOG(RDK_LOG_ERROR, LOG_BACKUP_LOGS,
+            "<function>: NULL config parameter\n");
+    return BACKUP_ERROR_INVALID_PARAM;
+}
+```
+
+**Non-fatal vs fatal failures:**
+
+| Condition | Behaviour |
+|-----------|-----------|
+| Disk threshold check script absent | Logged, execution continues |
+| Special file entry missing | Logged as warning, next entry processed |
+| Version file missing | Logged as warning, execution continues |
+| systemd notification failure | Logged, execution continues |
+| Config load failure | Fatal: `backup_logs_main()` returns error |
+| Directory creation failure | Fatal: execution aborted |
+
+**Logging levels used:**
+
+| Macro | When |
+|-------|------|
+| `RDK_LOG(RDK_LOG_ERROR, ...)` | Fatal conditions, invalid parameters |
+| `RDK_LOG(RDK_LOG_WARN, ...)` | Non-fatal issues, missing optional files |
+| `RDK_LOG(RDK_LOG_INFO, ...)` | Progress milestones, loaded values |
+| `RDK_LOG(RDK_LOG_DEBUG, ...)` | Entry/exit of functions, intermediate values |
+
+All messages use component name `LOG_BACKUP_LOGS` (`"LOG.RDK.BACKUPLOGS"`).
+
+---
+
+## Memory Management
+
+`backup_logs` uses exclusively static-size buffers; there is no heap allocation in the application code itself.
+
+```mermaid
+graph TD
+    A[backup_logs_main\nstack: backup_config_t ~4 KB] --> B[config_load\nstack buffers ≤32 B each]
+    A --> C[special_files_config_t\nstack: ~MAX_SPECIAL_FILES × PATH_MAX]
+    A --> D[backup_engine\nstack: per-file path buffers PATH_MAX]
+```
+
+**Allocation summary:**
+
+| Variable | Location | Size | Lifetime |
+|----------|----------|------|---------|
+| `backup_config_t` | Stack (`main`) | ≤ 4 × `PATH_MAX` + `bool` | Duration of `main()` |
+| `special_files_config_t` | Stack (caller) | 32 × `sizeof(special_file_entry_t)` ≈ ~256 KB max | Duration of caller scope |
+| Per-file path buffers in `move_log_files_by_pattern` | Stack | 2 × `PATH_MAX` | Single iteration |
+| Temporary property read buffers in `config_load` | Stack | 32 B each | Duration of `config_load()` |
+
+**Peak heap use:** Near zero (only what `librdkloggers`, `libfwutils`, and the C runtime allocate internally).
+
+**Ownership rules:**
+
+- `backup_config_t` is owned by `main()` and passed by pointer throughout; no module frees it.
+- `special_files_config_t` is owned by the caller of `special_files_load_config()`; call `special_files_config_free()` when done, even if populated only partially.
+- All string fields inside config structures are fixed-length arrays — no pointer ownership to manage.
+

+
+## Build Instructions
+
+### Prerequisites
+
+| Dependency | Package | Notes |
+|------------|---------|-------|
+| GCC / cross-compiler | Build environment | `std=c99`, `-Wall -Wextra` |
+| Autotools | autoconf 2.69+, automake 1.15+ | |
+| `librdkloggers` | RDK sysroot | Optional; enables RDK_LOG |
+| `libfwutils` | RDK sysroot | Required for property APIs |
+| `libsystemd` | sysroot or host | For `sd_notify` |
+| `libsecure_wrapper` | RDK sysroot | Safe string/IO operations |
+| `libm` | Standard libc | Math functions |
+
+### Build Steps
+
+```bash
+# From the repo root
+autoreconf -i
+
+# Native build
+./configure
+make
+
+# Cross-compile (ARM RDK target)
+./configure --host=arm-linux-gnueabihf \
+            PKG_CONFIG_SYSROOT_DIR=/path/to/sysroot
+make
+
+# Install
+make install
+```
+
+### Compile-time Flags
+
+| Flag | Effect |
+|------|--------|
+| `-DRDK_LOGGER_EXT` | Enable extended RDK logger with file output to `/tmp/backup_logs.log` |
+| `-DRDK_LOGGER_ENABLED` | Enable standard RDK logger (controlled by `/etc/debug.ini`) |
+
+Both flags are set in `backup_logs/Makefile.am`:
+```makefile
+backup_logs_CPPFLAGS = -I... -DRDK_LOGGER_EXT
+backup_logs_LDADD    = -lm -lrdkloggers -lfwutils -lsystemd -lsecure_wrapper
+```
+
+---
+
+## Unit Testing
+
+Unit tests use **Google Test** and **Google Mock** and reside in `backup_logs/unittest/`.
+
+| Test File | Module Covered |
+|-----------|---------------|
+| `backup_engine_gtest.cpp` | `backup_engine.c` — strategies, file pattern helpers |
+| `backup_logs_gtest.cpp` | `backup_logs.c` — init/execute/cleanup lifecycle |
+| `config_manager_gtest.cpp` | `config_manager.c` — property loading, path derivation |
+| `special_files_gtest.cpp` | `special_files.c` — config parsing, entry execution |
+| `sys_integration_gtest.cpp` | `sys_integration.c` — systemd notification paths |
+
+RBUS, RDK property, and file-system calls are stubbed using **mock control variables** (global struct pattern) so tests run without a live RDK environment.
+
+### Running Tests
+
+```bash
+# In the Docker CI container
+docker run --rm \
+  -v "$(pwd):/workspace" \
+  ghcr.io/rdkcentral/docker-rdk-ci:latest \
+  bash /workspace/unit_test.sh
+```
+
+### Coverage Target
+
+≥ 80% line coverage. Tests cover:
+
+- Normal paths for both HDD strategies
+- All 4 rotation levels in the HDD-disabled strategy
+- NULL and invalid parameter guards on every public function
+- `snprintf` truncation paths in config loading
+- Missing source files in special file processing
+- Systemd notification success and failure paths
+
+---
+
+## Configuration Files and Paths
+
+| File | Default Path | Purpose |
+|------|-------------|---------|
+| Include properties | `/etc/include.properties` | Source of `LOG_PATH` |
+| Device properties | `/etc/device.properties` | Source of `HDD_ENABLED`, `APP_PERSISTENT_PATH` |
+| Special files list | `/etc/backup_logs/special_files.conf` | Additional files to capture |
+| Disk check script | `/lib/rdk/disk_threshold_check.sh` | Optional pre-backup disk threshold check |
+| Debug configuration | `/etc/debug.ini` | RDK logger level settings |
+| Logger output | `/tmp/backup_logs.log` | Extended logger file output (when `-DRDK_LOGGER_EXT`) |
+| Persistent marker | `$APP_PERSISTENT_PATH/logFileBackup` | Signals backup completion across reboots |
+
+**Runtime directory layout after a successful backup:**
+
+```
+$LOG_PATH/
+├── PreviousLogs/
+│   ├── messages.txt          (HDD-disabled: base level)
+│   ├── bak1_messages.txt     (HDD-disabled: level 1)
+│   ├── bak2_messages.txt     (HDD-disabled: level 2)
+│   ├── bak3_messages.txt     (HDD-disabled: level 3)
+│   ├── logbackup-04-03-26-… (HDD-enabled: timestamped dir)
+│   └── last_reboot           (marker file)
+├── PreviousLogs_backup/      (cleaned before use)
+├── skyversion.txt
+├── rippleversion.txt
+└── version.txt
+```
+
+---
+
+## Platform Notes
+
+### Supported Architectures
+
+ARMv7, MIPS, x86 (cross-compilation via `--host=`).
+
+### Filesystem Compatibility
+
+Designed for ext4, JFFS2, and UBIFS. All directory operations use `createDir()` from `libfwutils`, which handles filesystem-specific permission and inode constraints.
+
+### Resource Constraints
+
+| Resource | Limit |
+|----------|-------|
+| Peak memory (application) | ≤ 512 KB |
+| Startup time | ≤ 2 s on target hardware |
+| File operation window | ≤ 30 s for typical log volumes |
+| CPU % during backup | ≤ 10% |
+| `MAX_SPECIAL_FILES` | 32 entries |
+
+### Security Considerations
+
+- All paths are constructed with `snprintf()` and bounds-checked; truncation returns an error rather than a silently-clipped path.
+- Source file paths in `special_files.conf` are processed without shell expansion, preventing command injection.
+- `secure_wrapper` (`libsecure_wrapper`) is linked to harden string and I/O operations.
+- Symlink safety: `filePresentCheck()` uses `stat()` (follows symlinks by design, consistent with the original shell script behaviour); callers validate the resolved path remains under expected directories.

+
+  @special_files @conditional_check @positive
+  Scenario: Special files conditional checks work correctly
+    Given the special_files.conf contains conditional entries
+    And some conditions evaluate to true and others to false
+    When backup_logs processes special files with conditions
+    Then only files meeting the true conditions should be processed
+    And conditional checks should be logged appropriately
+
+  @special_files @multiple_files @positive
+  Scenario: Multiple special files are processed in sequence
+    Given the special_files.conf contains multiple file entries
+    And all specified files exist with different content
+    When backup_logs processes all special files
+    Then all files should be processed according to their configuration
+    And each file operation should be logged separately
+    And the processing order should follow configuration order
+
+  @special_files @comment_handling @positive  
+  Scenario: Configuration file comments and blank lines are ignored
+    Given the special_files.conf contains comments and blank lines
+    And valid file paths are mixed with comments
+    When backup_logs parses the special files configuration
+    Then comments should be ignored during parsing
+    And blank lines should be skipped
+    And only valid file paths should be processed

+
+Feature: backup_logs Integration and Lifecycle Testing  
+  Corresponds to test_integration.py - covers full initialization sequence, backup execution lifecycle, systemd notification, and cleanup behavior
+
+  Background:
+    Given the backup_logs service is available
+    And the required system directories exist
+    And system configuration files are accessible
+
+  @initialization @lifecycle @positive
+  Scenario: backup_logs initialization completes successfully
+    Given all required directories and files are present
+    When backup_logs initializes the system
+    Then the initialization should complete without error
+    And the backup_logs.log should contain "Backup system initialization completed successfully"
+    And the system should return exit code 0
+
+  @initialization @error_handling @negative
+  Scenario: Initialization with invalid invocation is handled gracefully
+    Given backup_logs is invoked with invalid parameters
+    When the system attempts initialization
+    Then no segfault or crash should occur  
+    And the backup_logs.log should not contain "segfault", "core dump", or "signal 11"
+    And the system should handle the error gracefully
+
+  @execution @lifecycle @positive
+  Scenario: Backup execution process starts and is logged
+    Given backup_logs has initialized successfully
+    And log files are present for backup
+    When the backup execution process starts
+    Then the execution start should be logged in backup_logs.log
+    And the backup process should begin processing files
+
+  @execution @lifecycle @positive
+  Scenario: Complete backup execution returns success
+    Given backup_logs has initialized successfully
+    And log files are available for backup
+    When the complete backup execution runs
+    Then the backup should complete successfully
+    And the system should return exit code 0
+    And all expected backup operations should be performed
+
+  @systemd @notification @positive
+  Scenario: Systemd notification is sent on successful completion
+    Given backup_logs is running in systemd environment
+    And the backup operation completes successfully
+    When the backup process finishes
+    Then a systemd notification should be sent
+    And the notification should indicate successful completion
+    And systemd should be aware of the service status
+
+  @disk_threshold @resource_management @positive
+  Scenario: Disk threshold check is performed before backup
+    Given the disk threshold check script is available
+    And sufficient disk space exists for backup operations
+    When backup_logs performs disk space validation
+    Then the disk threshold script should be executed
+    And available space should be validated against requirements
+    And backup should proceed if space is adequate
+
+  @disk_threshold @insufficient_space @negative
+  Scenario: Backup is prevented when insufficient disk space
+    Given the disk threshold check script is available
+    And insufficient disk space exists for backup operations  
+    When backup_logs performs disk space validation
+    Then the disk threshold check should fail
+    And backup operations should be prevented
+    And an appropriate error message should be logged
+
+  @cleanup @resource_management @positive
+  Scenario: System cleanup performs proper resource cleanup
+    Given backup_logs has completed backup operations
+    And temporary files and resources were created during backup
+    When the cleanup process runs
+    Then all temporary files should be properly cleaned up
+    And system resources should be freed
+    And no orphaned processes or files should remain
+    And cleanup completion should be logged
+
+  @cleanup @file_handles @positive
+  Scenario: File handles are properly closed after operations
+    Given backup_logs has opened files for backup operations
+    When the backup operations complete
+    Then all file handles should be properly closed
+    And no file handle leaks should occur
+    And the system should release all file resources
+
+  @end_to_end @full_cycle @positive
+  Scenario: Complete end-to-end backup lifecycle
+    Given the system is in initial state
+    And configuration is properly set up
+    And log files are available for backup
+    When a complete backup cycle is executed
+    Then initialization should complete successfully
+    And configuration should be loaded and validated
+    And backup strategy should be selected based on configuration
+    And log files should be processed according to strategy
+    And special files should be handled if configured
+    And cleanup should complete successfully
+    And systemd notification should be sent
+    And the system should return to ready state

+Feature: USB Log Upload
+  This feature covers the USB log upload functionality, including error handling, archive creation, MAC address logging, temp directory cleanup, and success/failure scenarios.
+
+  Scenario: USB not mounted or missing log path
+    Given the USB log upload binary is available
+    When I run usblogupload with a non-existent mount point
+    Then the process should fail with code 2 or 3
+    And a failure message should be logged
+
+  Scenario: Archive creation on valid mount
+    Given a valid USB mount point
+    When I run usblogupload
+    Then the process should exit with code 0 or 3
+    And an archive creation log may appear
+
+  Scenario: MAC address and file log
+    Given a valid USB mount point
+    When I run usblogupload
+    Then the process should exit with code 0 or 3
+    And a log line with MAC address and file name may appear
+
+  Scenario: Temp directory cleanup
+    Given a valid USB mount point
+    When I run usblogupload
+    Then the process should exit with code 0 or 3
+    And a cleanup log may appear
+
+  Scenario: Successful USB log upload
+    Given the USB log upload binary is available
+    When I run usblogupload with a valid mount point
+    Then the process should exit with code 0
+    And a completion message should be logged
+
+  Scenario: Invalid usage
+    Given the USB log upload binary is available
+    When I run usblogupload with no arguments
+    Then the process should exit with code 4
+    And a log about failed logging system initialization may appear
+
+  Scenario: USB not mounted
+    Given the USB log upload binary is available
+    When I run usblogupload with an unmounted path
+    Then the process should exit with code 2
+    And a log about failed USB mount point validation may appear

+# UploadLogsNow Migration
+
+## Overview
+
+`UploadLogsNow.sh` has been migrated into the `uploadstblogs` C module as a dedicated execution path implemented in [uploadstblogs/src/uploadlogsnow.c](../src/uploadlogsnow.c) and exposed by [uploadstblogs/include/uploadlogsnow.h](../include/uploadlogsnow.h). Instead of shipping a separate shell script, the feature now runs as a special mode of the `logupload` binary and reuses the existing `uploadstblogs` archive and upload engine.
+
+The entry trigger is:
+
+```bash
+logupload uploadlogsnow
+```
+
+When this argument is detected, `parse_args()` enables `uploadlogsnow_mode`, sets the trigger to `TRIGGER_ONDEMAND`, and dispatches execution to the dedicated UploadLogsNow workflow rather than the standard strategy pipeline.
+
+## Purpose
+
+The migrated UploadLogsNow flow preserves the intent of the legacy script:
+
+- gather current log files immediately
+- stage them in a dedicated DCM temporary area
+- timestamp selected files using the legacy exclusion logic
+- create an archive with the shared archive manager
+- upload immediately using the existing on-demand upload path
+- record human-readable status in a persistent status file
+- clean up the temporary staging directory
+
+## External Consumers
+
+The original `UploadLogsNow.sh` flow was not only a local helper script; it was also used by external device-management components. After the migration, those consumers should be understood as depending on the `logupload uploadlogsnow` execution path and on the same observable status file semantics.
+
+### Verified Consumer: tr69hostif
+
+`tr69hostif` is a confirmed external consumer of the UploadLogsNow trigger path.
+
+### Consumer Integration Points
+
+| Consumer | Verified Integration | Details |
+|----------|----------------------|---------|
+| `rdkcentral/tr69hostif` | Yes | Uses TR-181 handlers to trigger `backgroundrun /usr/bin/logupload uploadlogsnow >> /opt/logs/dcmscript.log 2>&1` and reads `/opt/loguploadstatus.txt` for status |
+| `rdk-e/lostandfound-cpc` | Not yet verified | Consumer relationship has been reported, but file-level integration details have not yet been verified |
+
+### tr69hostif Trigger Path
+
+The verified trigger path in `tr69hostif` is:
+
+```text
+backgroundrun /usr/bin/logupload uploadlogsnow >> /opt/logs/dcmscript.log 2>&1
+```
+
+This command is defined as `LOG_UPLOAD_SCR` in the `DeviceInfo` profile and is executed from the TR-181 setter for the Upload Logs Now parameter.
+
+### Consumer-Side Files in tr69hostif
+
+| File | Role |
+|------|------|
+| `src/hostif/profiles/DeviceInfo/Device_DeviceInfo.h` | Defines `LOG_UPLOAD_SCR`, `CURRENT_LOG_UPLOAD_STATUS`, and TR-181 parameter constants |
+| `src/hostif/profiles/DeviceInfo/Device_DeviceInfo.cpp` | Implements `get/set_xOpsDMUploadLogsNow()` and `get_xOpsDMLogsUploadStatus()` |
+| `src/hostif/handlers/src/hostIf_DeviceClient_ReqHandler.cpp` | Routes GET/SET requests for the UploadLogsNow parameter |
+
+## Consumer Data Model Parameters
+
+The UploadLogsNow migration does not introduce a new data model inside `dcm-agent`. The consumer-facing control surface is exposed externally through TR-181 parameters in `tr69hostif`.
+
+### Verified TR-181 Parameters in tr69hostif
+
+| Parameter | Direction | Purpose |
+|-----------|-----------|---------|
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_xOpsDeviceMgmt.Logging.xOpsDMUploadLogsNow` | GET + SET | Trigger parameter used by external management systems to initiate UploadLogsNow |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_xOpsDeviceMgmt.Logging.xOpsDMLogsUploadStatus` | GET | Readback status parameter backed by `/opt/loguploadstatus.txt` |
+
+### Parameter Semantics
+
+#### `xOpsDMUploadLogsNow`
+
+- Type: boolean
+- Consumer: `tr69hostif`
+- Action on `true`: executes the migrated UploadLogsNow flow through `logupload uploadlogsnow`
+- Getter behavior in `tr69hostif`: currently returns `false` by default and acts mainly as a control point rather than a persistent state indicator
+
+#### `xOpsDMLogsUploadStatus`
+
+- Type: string
+- Consumer: `tr69hostif`
+- Backing file: `/opt/loguploadstatus.txt`
+- Purpose: exposes the last UploadLogsNow workflow status back to TR-181 clients
+
+The `tr69hostif` header comments document these valid status values:
+
+- `Not triggered`
+- `Triggered`
+- `In progress`
+- `Failed`
+- `Complete`
+
+These values align directly with the status-file semantics implemented in `uploadlogsnow.c`.
+
+### Data Model Relationship to dcm-agent
+
+From the `dcm-agent` side, the migration preserves consumer compatibility through these stable interfaces:
+
+| dcm-agent Surface | Consumer Dependency |
+|-------------------|---------------------|
+| `logupload uploadlogsnow` | external trigger command |
+| `/opt/loguploadstatus.txt` | external status readback |
+| UploadLogsNow-specific status strings | mapped to consumer data model status |
+
+### Access Note for lostandfound-cpc
+
+`lostandfound-cpc` was named as a consumer in the integration request, but its exact trigger file and any corresponding parameter or RPC surface have not yet been verified. This document therefore records it as a known external consumer while limiting detailed parameter documentation to the verified `tr69hostif` integration.

+
+## Runtime Behavior
+
+### Activation
+
+The mode is enabled in [uploadstblogs/src/uploadstblogs.c](../src/uploadstblogs.c) when the first argument is exactly `uploadlogsnow`.
+
+The parser then applies these UploadLogsNow-specific runtime defaults:
+
+| Field | Value |
+|-------|-------|
+| `flag` | `1` |
+| `dcm_flag` | `1` |
+| `upload_on_reboot` | `1` |
+| `trigger_type` | `TRIGGER_ONDEMAND` |
+| `rrd_flag` | `0` |
+| `tls_enabled` | `false` by default |
+| `uploadlogsnow_mode` | `true` |
+
+### Workflow Steps
+
+The implementation in `execute_uploadlogsnow_workflow()` performs these stages:
+
+1. Validate the input `RuntimeContext`
+2. Write initial status `Triggered` to the status file
+3. Resolve `DCM_LOG_PATH` from `ctx->dcm_log_path`, or use `DCM_TEMP_DIR` (`/tmp/DCM`)
+4. Create the DCM staging directory
+5. Copy files from `LOG_PATH` to the DCM staging directory
+6. If no files were copied, write `No files to upload` and exit successfully
+7. Add timestamp prefixes using UploadLogsNow-specific exclusions
+8. Write status `In progress`
+9. Create an archive in the staging directory with `create_archive()`
+10. Verify the archive exists
+11. Replace `session.archive_file` with the full archive path
+12. Select upload paths via `decide_paths()`
+13. Execute upload with `execute_upload_cycle()`
+14. Write final status `Complete` or `Failed`
+15. Remove the temporary DCM staging directory

+
+## Key Files and Constants
+
+### Source Files
+
+| File | Role |
+|------|------|
+| [uploadstblogs/src/uploadlogsnow.c](../src/uploadlogsnow.c) | Dedicated UploadLogsNow workflow implementation |
+| [uploadstblogs/include/uploadlogsnow.h](../include/uploadlogsnow.h) | Public declaration for `execute_uploadlogsnow_workflow()` |
+| [uploadstblogs/src/uploadstblogs.c](../src/uploadstblogs.c) | Mode detection and dispatch |
+| [uploadstblogs/include/file_operations.h](../include/file_operations.h) | UploadLogsNow-specific timestamp helper declaration |
+
+### Constants
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `STATUS_FILE` | `/opt/loguploadstatus.txt` | User-visible workflow status file |
+| `DCM_TEMP_DIR` | `/tmp/DCM` | Default staging directory when no DCM path is configured |
+| `LOG_UPLOADSTB` | `LOG.RDK.UPLOADSTB` | RDK logging component |
+
+## File Selection and Exclusions
+
+### Copy Exclusions
+
+The UploadLogsNow copy stage intentionally excludes these names from the source log directory:
+
+| Excluded Name | Reason |
+|---------------|--------|
+| `dcm` | Avoid recursive or unrelated DCM area capture |
+| `PreviousLogs_backup` | Skip rotated backup data |
+| `PreviousLogs` | Skip historical backup content |
+
+If a path is too long to fit inside `MAX_PATH_LENGTH`, that entry is skipped and a warning is logged instead of truncating the path.
+
+### Timestamping Behavior
+
+UploadLogsNow uses `add_timestamp_to_files_uploadlogsnow()` rather than the generic timestamp helper.
+
+This special variant is documented in [uploadstblogs/include/file_operations.h](../include/file_operations.h) as skipping:
+
+- files that already carry an `AM`/`PM` timestamp prefix
+- reboot logs
+- ABL reason logs
+
+That preserves the shell-script behavior and avoids renaming files that should remain stable.
+
+## API Reference
+
+### `execute_uploadlogsnow_workflow()`
+
+Executes the migrated UploadLogsNow workflow.
+
+**Signature**
+
+```c
+int execute_uploadlogsnow_workflow(RuntimeContext* ctx);
+```
+
+**Parameters**
+
+- `ctx` - initialized runtime context with `log_path`, optional `dcm_log_path`, and upload configuration
+
+**Returns**
+
+- `0` on success
+- `-1` on failure
+
+**Behavior Notes**
+
+- returns `0` when the source log directory contains no files to upload
+- writes status updates to `STATUS_FILE` across the run
+- always attempts to remove the DCM staging directory before returning
+
+### Internal Helper Behavior
+
+`uploadlogsnow.c` contains two internal helpers that are central to the migrated script behavior:
+
+| Helper | Responsibility |
+|--------|----------------|
+| `write_upload_status()` | writes status text with timestamp to `/opt/loguploadstatus.txt` |
+| `copy_files_to_dcm_path()` | copies source logs into the staging directory with exclusion filtering |
+
+## Status File Semantics
+
+The workflow writes user-facing progress to `/opt/loguploadstatus.txt`.
+
+### Status Values
+
+| Status | When Written |
+|--------|--------------|
+| `Triggered` | immediately after workflow start |
+| `In progress` | after staging and before archive/upload execution |
+| `No files to upload` | when source log directory is empty |
+| `Complete` | after successful upload |
+| `Failed` | on a terminal error |
+
+### File Format
+
+Each status line is written as:
+
+```text
+<message> <ctime timestamp>
+```
+
+If `ctime_r()` is unavailable for some reason, only the message is written.
+
+## Upload Path Behavior
+
+After archive creation, UploadLogsNow intentionally reuses the normal `uploadstblogs` upload machinery instead of maintaining a separate transport implementation.
+
+### Reused Functions
+
+| Function | Purpose |
+|----------|---------|
+| `create_archive()` | package staged logs into an archive |
+| `decide_paths()` | choose Direct vs CodeBig primary/fallback |
+| `execute_upload_cycle()` | perform pre-sign, upload, retry, and fallback |
+
+This keeps UploadLogsNow aligned with the rest of the module for:
+
+- authentication behavior
+- retry logic
+- path blocking rules
+- success/failure verification
+- event and telemetry integration
+
+## Error Handling
+
+### Fatal Failures
+
+| Failure | Result |
+|---------|--------|
+| null `RuntimeContext` | immediate `-1` return |
+| staging directory creation failure | status `Failed`, return `-1` |
+| file copy failure | status `Failed`, return `-1` |
+| archive creation failure | status `Failed`, return `-1` |
+| archive missing after creation | status `Failed`, return `-1` |
+| upload execution failure | status `Failed`, return `-1` |
+
+### Non-Fatal Behavior
+
+| Condition | Behavior |
+|-----------|----------|
+| no files found in `LOG_PATH` | status `No files to upload`, return `0` |
+| timestamp helper failure | warning logged, upload continues |
+| cleanup directory removal failure | warning logged after main result is decided |
+
+## Threading Model
+
+UploadLogsNow is single-threaded and runs within the same process context as `logupload`.
+
+| Aspect | Behavior |
+|--------|----------|
+| Worker threads | none |
+| Concurrency control | inherited file lock from `uploadstblogs_execute()` |
+| Shared state | one `RuntimeContext`, one local `SessionState` |
+
+Because the lock is acquired before UploadLogsNow dispatch, the migrated script remains single-instance just like the broader upload flow.
+
+## Memory Management
+
+The migrated implementation uses fixed-size stack buffers and shared filesystem helpers.
+
+### Main Local Buffers
+
+| Buffer | Size Source | Purpose |
+|--------|-------------|---------|
+| `dcm_log_path` | `MAX_PATH_LENGTH` | resolved staging directory |
+| `src_file` / `dest_file` | `MAX_PATH_LENGTH` | per-file copy path construction |
+| `full_archive_path` | `MAX_PATH_LENGTH` | archive existence verification |
+| `timebuf` | 26 bytes | status-file timestamp formatting |
+
+### Allocation Pattern
+
+```mermaid
+graph TD
+    A[RuntimeContext from uploadstblogs] --> B[Create /tmp/DCM or configured DCM path]
+    B --> C[Copy files into staging dir]
+    C --> D[Rename with timestamps]
+    D --> E[Create archive]
+    E --> F[Upload via shared engine]
+    F --> G[Remove staging dir]
+```
+
+No additional heap-owned module state is introduced by the UploadLogsNow migration.
+
+## Testing
+
+There is dedicated unit-test coverage for this migrated workflow in [uploadstblogs/unittest/uploadlogsnow_gtest.cpp](../unittest/uploadlogsnow_gtest.cpp).
+
+### Covered Scenarios
+
+| Test Area | Example Cases |
+|-----------|---------------|
+| parameter validation | null context |
+| staging creation | create-directory failure |
+| copy stage | copy failure |
+| archive stage | archive creation failure, archive not found |
+| upload stage | upload cycle success/failure |
+| empty source directory | returns success with no files |
+
+The tests mock:
+
+- directory creation and removal
+- file copy operations
+- timestamp helper behavior
+- archive creation
+- upload cycle result
+
+## Usage Example
+
+### CLI Invocation
+
+```bash
+logupload uploadlogsnow
+```
+
+### Expected High-Level Behavior
+
+1. create `/tmp/DCM` if no DCM path is preconfigured
+2. copy eligible files from `LOG_PATH`
+3. timestamp staged files
+4. create an archive in the staging directory
+5. upload immediately using on-demand semantics
+6. update `/opt/loguploadstatus.txt`
+7. remove the staging directory
+
+## Platform Notes
+
+- intended for RDK embedded Linux targets
+- preserves shell-script semantics while removing shell dependency
+- uses shared `uploadstblogs` transport and event behavior rather than duplicating upload code
+- avoids dynamic memory-heavy workflows and shell glob expansion

+# uploadSTBLogs Module
+
+## Overview
+
+`uploadstblogs` is the primary log packaging and upload subsystem used by DCM Agent. It is implemented as both a shared library (`libuploadstblogs.la`) and a standalone binary (`logupload`). The module replaces the legacy `uploadSTBLogs.sh` flow with a structured C implementation that performs runtime context loading, strategy selection, archive creation, secure upload, retry and fallback handling, verification, cleanup, and event/telemetry notification.
+
+The implementation is designed for embedded RDK targets with limited memory and CPU. It uses fixed-size buffers, a single-instance file lock, deterministic strategy selection, and explicit fallback rules between Direct and CodeBig upload paths.

+## Architecture
+
+`uploadstblogs` follows a strict staged pipeline that mirrors the design diagrams in the module HLD:
+
+1. Main entry and argument parsing
+2. Runtime context initialization
+3. System validation
+4. Early-return checks and strategy selection
+5. Archive creation and log collection
+6. Upload execution with retry/fallback
+7. Verification, cleanup, telemetry, and event emission

+
+## Core Modules
+
+### Entry Layer
+
+The public entry points are declared in `include/uploadstblogs.h` and expose both library and binary style invocation.
+
+| API | Purpose |
+|-----|---------|
+| `uploadstblogs_run()` | Preferred structured API for external callers such as DCM |
+| `uploadstblogs_execute()` | Internal argc/argv-compatible execution path |
+| `parse_args()` | CLI-to-context mapping |
+| `acquire_lock()` / `release_lock()` | Single-instance guard using file locking |
+
+### Context and Validation Layer
+
+The context manager populates a flat `RuntimeContext` structure with:
+
+- upload flags
+- privacy and OCSP settings
+- log and temp paths
+- endpoint URLs
+- device identifiers
+- certificate paths
+- retry tuning
+
+Validation is performed before any packaging or upload begins so the module can fail early on missing directories, missing binaries, or unsupported runtime conditions.
+
+### Strategy Layer
+
+`strategy_selector` determines which high-level behavior applies to the current invocation. `strategy_handler` and `strategies` then execute the selected branch while preserving the same observable behavior as the legacy shell workflow.
+
+### Archive and Upload Layer
+
+`archive_manager` collects candidate logs and produces a `.tgz` archive. `upload_engine` then:
+
+- decides the primary path (`PATH_DIRECT` or `PATH_CODEBIG`)
+- performs the pre-sign step
+- attempts the upload
+- evaluates retry policy
+- optionally switches to the fallback path
+- returns a final success/failure result for verification and cleanup
+
+---
+
+## Data Model
+
+The principal types are defined in `include/uploadstblogs_types.h`.
+
+### `UploadSTBLogsParams`
+
+Structured external-call API used by DCM and other components.
+
+```c

+    TriggerType trigger_type;
+    bool rrd_flag;
+    const char* rrd_file;
+} UploadSTBLogsParams;
+```
+
+### `RuntimeContext`
+
+The full flattened runtime state for one execution.

+} RuntimeContext;
+```
+
+### `SessionState`
+
+Tracks one upload attempt sequence.
+
+```c
+typedef struct {
+    Strategy strategy;
+    UploadPath primary;
+    UploadPath fallback;
+    int direct_attempts;
+    int codebig_attempts;
+    int http_code;
+    int curl_code;
+    bool used_fallback;

+    M --> N[event + telemetry]
+    N --> O[cleanup]
+    O --> P[release_lock]
+```
+
+Key decisions are deterministic and follow the documented branch order so that behavior remains consistent across releases and platforms.
+
+---
+
+## Strategy Selection
+
+The early-check logic is declared in `include/strategy_selector.h`.
+
+### Strategy Decision Table
+
+| Condition | Selected Strategy |
+|-----------|-------------------|
+| `RRD_FLAG == 1` | `STRAT_RRD` |
+| Privacy mode enabled | `STRAT_PRIVACY_ABORT` |
+| Previous logs absent/empty | `STRAT_NO_LOGS` |
+| `TriggerType == TRIGGER_ONDEMAND` | `STRAT_ONDEMAND` |
+| `DCM_FLAG == 0` | `STRAT_NON_DCM` |
+| `UploadOnReboot == 1 && FLAG == 1` | `STRAT_REBOOT` |
+| Otherwise | `STRAT_DCM` |
+
+### Path Selection Rules
+
+| Rule | Outcome |
+|------|---------|
+| Direct not blocked | `PATH_DIRECT` becomes primary |
+| Direct blocked, CodeBig open | `PATH_CODEBIG` becomes primary |
+| Both blocked | Terminal failure |
+| Non-terminal failure and alternate open | Single fallback switch allowed |
+| HTTP 404 on pre-sign | Terminal, no retry/fallback loop |
+
+---
+
+## Upload Paths and Security
+
+### Direct Path
+
+- Uses mTLS with client certificate, key, and CA files
+- Intended as the preferred fast path when not blocked
+- Supports optional OCSP behavior based on runtime markers/configuration
+
+### CodeBig Path
+
+- Uses OAuth-based authorization flow
+- Acts as the alternate route when Direct is blocked or exhausted
+- Uses separate retry parameters and block-marker logic
+
+### Security Controls
+
+- privacy mode abort prevents log upload
+- TLS minimum behavior is controlled by runtime flags
+- signatures and sensitive upload artifacts should not be logged verbatim
+- file lock prevents overlapping upload sessions
+
+---
+
+## API Reference
+
+### `uploadstblogs_run()`
+
+Preferred external interface.
+
+**Signature**
+
+```c
+int uploadstblogs_run(const UploadSTBLogsParams* params);
+```
+
+**Parameters**
+
+- `params`: caller-owned parameter block describing trigger, URL, protocol, and flags
+
+**Returns**
+
+- `0` on success
+- `1` on failure
+
+**Thread Safety**
+
+The implementation uses a single-instance file lock to serialize active runs across processes. However, `uploadstblogs_run()` is not safe for concurrent calls from multiple threads within the same process and is not re-entrant, because it relies on shared static/global runtime state. Callers must ensure that invocations within a process are externally serialized.
+
+### `uploadstblogs_execute()`
+
+argc/argv-compatible execution path used by the standalone binary and compatibility callers.
+
+**Signature**
+
+```c
+int uploadstblogs_execute(int argc, char** argv);
+```
+
+### `parse_args()`
+
+Maps CLI input into an already-initialized `RuntimeContext`.
+
+**Signature**
+
+```c
+bool parse_args(int argc, char** argv, RuntimeContext* ctx);
+```
+
+### `init_context()`
+
+Loads environment variables, device properties, TR-181 values, and runtime defaults.
+
+**Signature**
+
+```c
+bool init_context(RuntimeContext* ctx);
+```
+
+### `early_checks()`
+
+Performs early-return logic and selects the strategy.
+
+**Signature**
+
+```c
+Strategy early_checks(const RuntimeContext* ctx);
+```
+
+### `execute_upload_cycle()`
+
+Runs pre-sign, transfer, retry, and fallback orchestration.
+
+**Signature**
+
+```c
+bool execute_upload_cycle(RuntimeContext* ctx, SessionState* session);
+```
+
+### `collect_logs()` and `create_archive()`
+
+Handle file collection and archive generation.
+

+                 const char* dest_dir);
+int create_archive(RuntimeContext* ctx, SessionState* session,
+                   const char* source_dir);
+```
+
+---
+
+## Usage Examples
+
+### Library Call from DCM Agent
+
+```c
+#include "uploadstblogs.h"
+
+int run_scheduled_upload(void)
+{
+    UploadSTBLogsParams params = {
+        .flag = 0,
+        .dcm_flag = 1,
+        .upload_on_reboot = false,
+        .upload_protocol = "HTTP",
+        .upload_http_link = "https://example.com/upload",
+        .trigger_type = TRIGGER_SCHEDULED,
+        .rrd_flag = false,
+        .rrd_file = NULL
+    };
+
+    return uploadstblogs_run(&params);
+}
+```
+
+### Standalone Binary Invocation
+
+```bash
+logupload <TFTP_SERVER> <FLAG> <DCM_FLAG> <UploadOnReboot> \
+          <UploadProtocol> <UploadHttpLink> <TriggerType> \
+          <RRD_FLAG> <RRD_UPLOADLOG_FILE>
+```
+
+### UploadLogsNow Shortcut
+
+```bash
+logupload uploadlogsnow
+```
+
+This special mode is recognized in `parse_args()` and maps directly to an on-demand execution profile. The dedicated migration details are documented in [uploadlogsnow.md](uploadlogsnow.md).
+
+---
+
+## Threading Model
+
+`uploadstblogs` is effectively single-threaded during normal execution.
+
+| Aspect | Behavior |
+|--------|----------|
+| Worker threads | None created by this module |
+| Concurrency control | File lock via `acquire_lock()` / `release_lock()` |
+| Shared-state model | One `RuntimeContext` and one `SessionState` per run |
+| Re-entrancy | Serialized at process/library entry by lock |
+
+There are no internal mutexes or condition variables in the public interface. The concurrency guarantee is based on preventing overlapping runs rather than supporting parallel upload sessions.
+
+---
+
+## Memory Management
+
+The module is designed for low-footprint embedded systems and uses fixed-size stack and in-struct buffers extensively.
+
+### Allocation Pattern
+
+```mermaid
+graph TD
+    A[Caller allocates UploadSTBLogsParams] --> B[uploadstblogs_run]
+    B --> C[Stack RuntimeContext]
+    B --> D[Stack SessionState]
+    D --> E[collect_logs into temp dir]
+    E --> F[create_archive]
+    F --> G[cleanup temp/archive state]
+```
+
+### Ownership Rules
+
+| Resource | Owner | Cleanup |
+|----------|-------|---------|
+| `UploadSTBLogsParams` | Caller | Caller |
+| `RuntimeContext` | Current run | Automatic (stack) |
+| `SessionState` | Current run | Automatic (stack) |
+| Temporary files and archive | Module during run | `cleanup_handler` |
+| RBUS/context side resources | Module | `cleanup_context()` |
+
+### Buffering Strategy
+
+- `MAX_PATH_LENGTH = 512`
+- `MAX_URL_LENGTH = 1024`
+- `MAX_FILENAME_LENGTH = 256`
+- `MAX_CERT_PATH_LENGTH = 256`
+
+This avoids frequent heap allocation and makes behavior predictable under constrained memory conditions.
+

+
+## Build Instructions
+
+### Outputs
+
+| Output | Type |
+|--------|------|
+| `libuploadstblogs.la` | Shared library |
+| `logupload` | Standalone binary |
+
+### Build Dependencies
+
+From `src/Makefile.am`, the module links against:
+
+- `libcurl`
+- `librdkloggers`
+- `ldwnlutil`
+- `lrbus`
+- `lcjson`
+- `lsecure_wrapper`
+- `lfwutils`
+- `lcrypto`
+- `lrfcapi`
+- `lz`
+- `lIARMBus`
+- `lt2utils`
+- `ltelemetry_msgsender`
+- `luploadutil`
+
+### Common Build Steps
+
+```bash
+autoreconf -i
+./configure
+make
+make install
+```
+
+### Key Compile Flags
+
+| Flag | Purpose |
+|------|---------|
+| `-DEN_MAINTENANCE_MANAGER` | Maintenance manager integration |
+| `-DIARM_ENABLED` | IARM event support |
+| `-DT2_EVENT_ENABLED` | Telemetry event support |
+| `-DUPLOADSTBLOGS_BUILD_BINARY` | Enables binary entry mode |
+
+---
+
+## Testing
+
+Unit tests are under `uploadstblogs/unittest/` and cover nearly every module boundary.
+
+| Test File | Coverage Area |
+|-----------|---------------|
+| `uploadstblogs_gtest.cpp` | top-level execution and API behavior |
+| `context_manager_gtest.cpp` | runtime context loading |
+| `validation_gtest.cpp` | validation branches |
+| `strategy_selector_gtest.cpp` | early-check decision tree |
+| `strategy_handler_gtest.cpp` | strategy dispatch |
+| `strategies_gtest.cpp` | concrete strategies |
+| `archive_manager_gtest.cpp` | archive creation and naming |
+| `upload_engine_gtest.cpp` | retry/fallback/upload execution |
+| `retry_logic_gtest.cpp` | retry policy behavior |
+| `verification_gtest.cpp` | HTTP/curl result interpretation |
+| `event_manager_gtest.cpp` | event and telemetry paths |
+| `log_collector_gtest.cpp` | log collection and input gathering |
+| `rbus_interface_gtest.cpp` | RBUS integration |
+| Helper coverage note | `file_operations`, `path_handler`, and `md5_utils` are covered indirectly through the above tests and mocks; there are no dedicated `file_operations*_gtest.cpp` unit test sources |
+
+Typical execution is performed through the repository test harness in the CI container.
+

+
+## Configuration and Runtime Inputs
+
+### Inputs
+
+| Input Class | Examples |
+|-------------|----------|
+| CLI arguments | upload flags, DCM flags, protocol, URL, trigger, RRD file |
+| Environment / properties | `/etc/include.properties`, `/etc/device.properties` |
+| Runtime configuration | TR-181 parameters, RFC values, RBUS state |
+| Filesystem state | previous logs, block markers, reboot reason, temp directories |
+| Security assets | cert, key, CA cert paths |
+
+### Outputs
+
+| Output | Description |
+|--------|-------------|
+| `.tgz` archive | Packaged logs for upload |
+| upload result | success, failure, abort, retry |
+| telemetry | success/failure/fallback/error counters |
+| events | system notification of result |
+| cleanup effects | temp archive deletion, marker updates |
+
+---
+
+## Error Handling and Observability
+
+Observability is based on RDK logging plus optional T2 telemetry notifications.
+
+### Logging and Telemetry
+
+| Facility | Purpose |
+|----------|---------|
+| `RDK_LOG(...)` | stage-by-stage diagnostic logging |
+| `t2_count_notify()` | telemetry counters |
+| `t2_val_notify()` | telemetry string values |
+| event manager | upload result signaling |
+
+### Expected Failure Modes
+
+| Failure | Behavior |
+|---------|----------|
+| privacy mode | abort upload, no data transfer |
+| no previous logs | early return |
+| archive creation failure | emit failure path and cleanup |
+| pre-sign HTTP 404 | terminal failure, no fallback loop |
+| curl timeout / transient failure | retry or fallback if allowed |
+| both paths blocked | immediate failure |
+| cert or TLS error | log and count telemetry; may retry per policy |
+
+---
+
+## Platform Notes
+
+- built for RDK embedded Linux targets
+- portable across architectures supported by the Autotools build
+- designed to avoid shell-heavy orchestration
+- uses fixed-size buffers to reduce fragmentation risk
+- assumes POSIX filesystem, locking, and networking primitives
+
+---
+
+## External Consumers
+
+The migrated `uploadstblogs` implementation is consumed in several different ways across the RDK stack. Some components invoke the installed `/usr/bin/logupload` binary directly, some link against the `uploadstblogs_run()` API, and some still retain the legacy `uploadSTBLogs.sh` task name as part of maintenance orchestration while the actual execution path has moved to the C implementation.
+
+| Consumer | Integration Mode | Verified Usage |
+|----------|------------------|----------------|
+| `sysint` | direct binary execution | `lib/rdk/Start_MaintenanceTasks.sh` invokes `/usr/bin/logupload` for regular and on-demand maintenance log upload flows. The same repository changelog records removal of the legacy logupload shell scripts after porting to C. |
+| `remote_debugger` | direct library/API call | `rrd_upload.c` prepares `UploadSTBLogsParams` and calls `uploadstblogs_run(&params)` with `TRIGGER_ONDEMAND`, `rrd_flag=true`, and an explicit archive path for remote-debug-report uploads. |
+| `entservices-systemservices` | direct binary execution behind JSON-RPC | `plugin/uploadlogs.cpp` forks and `execve()`s `/usr/bin/logupload`, while `SystemServices` exposes `uploadLogsAsync` and `abortLogUpload` as the external control surface. |
+| `tr69hostif` | direct binary execution behind TR-181 | `Device_DeviceInfo` maps `xOpsDMUploadLogsNow` to `backgroundrun /usr/bin/logupload uploadlogsnow` and exposes upload status through `xOpsDMLogsUploadStatus`. |
+| `entservices-maintenancemanager` | legacy task orchestration reference | maintenance task tables still include the `uploadSTBLogs.sh` task identity and `MAINT_LOGUPLOAD_*` state handling. This preserves scheduler/orchestrator compatibility while downstream execution moves to the binary path. |
+| `entservices-softwareupdate` | legacy task orchestration reference | maintenance scheduling code also retains the `uploadSTBLogs.sh` task name and log-upload state tracking as part of the broader maintenance workflow. |
+| `dcm-agent` | native provider | this repository builds the `uploadstblogs` library and the `logupload` binary that the above consumers depend on. |
+
+### Consumers Not Directly Confirmed
+
+| Repository | Current Assessment |
+|------------|--------------------|
+| `crashupload` | current code-backed search did not confirm a direct call to `logupload`, `uploadSTBLogs.sh`, or `uploadstblogs_run()`. Its upload path is centered on crash/minidump transport rather than STB log upload. |
+| `performancetool` | not currently confirmed in this document. Add it here only after a code-backed reference to `logupload` or `uploadstblogs_run()` is available. |
+
+---
+
+## Consumer Data Model and Configuration Parameters
+
+The upload module does not expose a single universal control API. External components depend on a mix of TR-181 parameters, RFC values, JSON-RPC methods, and DCM-generated configuration files.
+
+### TR-181 and RFC Parameters
+
+| Parameter | Primary Consumer | Purpose |
+|-----------|------------------|---------|
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_xOpsDeviceMgmt.Logging.xOpsDMUploadLogsNow` | `tr69hostif` | write-triggered on-demand upload. Setting this to `true` causes `tr69hostif` to launch `logupload uploadlogsnow`. |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_xOpsDeviceMgmt.Logging.xOpsDMLogsUploadStatus` | `tr69hostif` | readback status parameter backed by `/opt/loguploadstatus.txt`. Used to expose current or last upload result. |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.LogUpload.LogServerUrl` | `remote_debugger` | RFC source for log server selection when remote debugger prepares upload parameters. |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.LogUpload.SsrUrl` | `remote_debugger` | RFC source for upload endpoint base URL; remote debugger appends `/cgi-bin/S3.cgi` when forming the final HTTP upload URL. |
+| `Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Feature.LogUploadEndpoint.URL` | `sysint` | maintenance-wrapper override for the upload endpoint, used when bootstrap/DCM settings are not meant to be authoritative. |
+
+### Configuration Files and Keys
+
+| Configuration Source | Primary Consumer | Keys / Usage |
+|----------------------|------------------|--------------|
+| `/tmp/DCMSettings.conf` | `sysint`, `entservices-systemservices`, `remote_debugger` | parsed for `LogUploadSettings:UploadRepository:uploadProtocol`, `LogUploadSettings:UploadRepository:URL`, and `LogUploadSettings:UploadOnReboot`. |
+| `/etc/dcm.properties` or `/opt/dcm.properties` | `sysint`, `entservices-systemservices`, `remote_debugger` | fallback source for `LOG_SERVER`, `HTTP_UPLOAD_LINK`, build-type specific overrides, and non-prod endpoint substitution. |
+| `/etc/include.properties` | `remote_debugger` | provides base runtime properties such as `RDK_PATH` and `LOG_PATH` during upload orchestration. |
+| `/etc/device.properties` | `entservices-systemservices`, `remote_debugger` | used for build-type and device capability checks such as `BUILD_TYPE` and `FORCE_MTLS`. |
+
+### External Control Surfaces
+
+| Control Surface | Consumer | Notes |
+|-----------------|----------|-------|
+| `uploadLogsAsync` / `abortLogUpload` | `entservices-systemservices` | Thunder/JSON-RPC methods that indirectly manage `/usr/bin/logupload`. |
+| `MAINT_LOGUPLOAD_*` event/state handling | `entservices-maintenancemanager`, `entservices-softwareupdate`, `sysint` | maintenance workflow state model that still treats log upload as a first-class scheduled task. |
+| `uploadstblogs_run(const UploadSTBLogsParams*)` | `remote_debugger` | preferred in-process integration for uploads that already have a prepared archive and do not want to shell out to the installed binary. |

+# USB Log Upload Module
+
+## Overview
+
+This module provides the C implementation of USB log upload functionality, migrated from the original `usbLogUpload.sh` shell script. It enables transfer of system logs from embedded devices to external USB storage with compression and proper naming conventions.
+
+## Architecture
+
+The module follows a layered modular architecture:
+
+### Core Modules
+
+1. **Main Control Module** (`usb_log_main.c/.h`)
+   - Application entry point and argument parsing
+   - High-level workflow orchestration
+   - Exit code management
+
+2. **Validation Module** (`usb_log_validation.c/.h`)
+   - Device compatibility verification
+   - USB mount point validation
+   - Input parameter validation
+
+3. **File Manager Module** (`usb_log_file_manager.c/.h`)
+   - Log file discovery and management
+   - Directory operations
+   - File movement and copying
+
+4. **Archive Manager Module** (`usb_log_archive.c/.h`)
+   - Log file compression and archiving
+   - Archive naming convention implementation
+   - Compression error handling
+
+5. **Utility Module** (`usb_log_utils.c/.h`)
+   - Common utility functions
+   - Logging and configuration management
+   - Error handling
+
+## Building
+
+### Prerequisites
+
+- GCC compiler
+- Autotools (autoconf, automake)
+- Standard C library
+
+### Build Instructions
+
+```bash
+# Using configure script
+./configure
+make
+make install
+
+# Or using direct Makefile
+make all
+```
+
+### Debug Build
+
+```bash
+./configure --enable-debug
+make
+```
+
+## Usage
+
+```bash
+usblogupload <USB_mount_point>
+```
+
+### Example
+
+```bash
+usblogupload /mnt/usb
+```
+
+## Exit Codes
+
+- `0`: Success
+- `2`: USB not mounted
+- `3`: Writing error to USB
+- `4`: Invalid usage or unsupported device
+
+## Configuration
+
+The module reads configuration from:
+- `/etc/include.properties`
+- `/etc/device.properties`
+
+### Environment Variables
+
+- `DEVICE_NAME`: Device type identifier (must be "TV")
+- `RDK_PATH`: RDK library path (default: `/lib/rdk`)
+- `LOG_PATH`: System log directory path
+- `SYSLOG_NG_ENABLED`: Syslog-ng service status
+
+## Features
+
+- **Device Validation**: Supports TV devices only
+- **Log Archival**: Creates compressed `.tgz` archives
+- **Naming Convention**: `<MAC>_Logs_<timestamp>.tgz`
+- **Service Management**: Reloads syslog-ng after log transfer
+- **Error Handling**: Comprehensive error checking and reporting
+
+## Testing
+
+### Unit Tests
+
+```bash
+# Build and run unit tests
+make test
+./bin/test_usblogupload
+```
+
+### Google Test Framework
+
+Unit tests use Google Test and Google Mock frameworks:
+
+```bash
+# Run GTest unit tests
+cd unittest
+make && ./run_tests
+```
+

+# USB Log Upload - Shared Functions Analysis
+
+## Functions from uploadstblogs that can be reused:
+
+### File Operations (`file_operations.h/c`)
+**Highly Reusable:**
+- `file_exists(const char* filepath)` - Check if file exists
+- `dir_exists(const char* dirpath)` - Check if directory exists  
+- `create_directory(const char* dirpath)` - Create directory recursively
+- `remove_file(const char* filepath)` - Remove file
+- `remove_directory(const char* dirpath)` - Remove directory recursively
+- `join_path(char* buffer, size_t buffer_size, const char* dir, const char* filename)` - Safely join paths
+- `get_file_size(const char* filepath)` - Get file size in bytes
+- `move_directory_contents(const char* src_dir, const char* dest_dir)` - Move all directory contents
+
+### Archive Management (`archive_manager.h/c`)
+**Highly Reusable:**
+- `generate_archive_name(char* buffer, size_t buffer_size, const char* mac_address, const char* prefix)` 
+  - Generates filenames in format: `<MAC>_Logs_<MM-DD-YY-HH-MMAM/PM>.tgz`
+  - Removes colons from MAC address automatically
+- `create_archive(RuntimeContext* ctx, SessionState* session, const char* source_dir)`
+  - Creates tar.gz archives (matches usbLogUpload.sh tar -zcvf requirement)
+
+### Validation (`validation.h/c`) 
+**Partially Reusable:**
+- `validate_directories(const RuntimeContext* ctx)` - Check required directories exist
+- `validate_binaries(void)` - Check required system binaries are available
+
+### System Utilities Pattern
+**Adaptable:**
+- Timestamp generation in format `MM-DD-YY-HH-MMAM/PM` (matches usbLogUpload.sh)
+- MAC address retrieval and formatting
+- Configuration file parsing patterns
+- Error logging and debugging patterns
+
+## Recommended Integration Strategy:
+
+1. **Direct Reuse:** 
+   - File operations functions for directory/file management
+   - Archive name generation for consistent filename format
+   - Path joining utilities for safe path construction
+
+2. **Adaptation Required:**
+   - Archive creation (adapt for USB-specific requirements)
+   - MAC address retrieval (may need USB-specific implementation)
+   - Validation functions (adapt for USB-specific checks)
+
+3. **USB-Specific Implementation:**
+   - USB mount point validation
+   - Device compatibility checks (TV-only requirement)
+   - syslog-ng service restart logic
+
+## Implementation Benefits:
+
+- **Code Reuse:** ~70% of utility functions can be directly reused
+- **Consistency:** Same filename format and archive structure
+- **Reliability:** Well-tested functions from existing uploadstblogs module
+- **Maintainability:** Single source of truth for common operations

+## 4. Data Structures
+
+### 4.1 Core Data Types
+
+```c
+// Configuration structure
+typedef struct {
+    char device_name[MAX_DEVICE_NAME_LEN];
+    char rdk_path[MAX_PATH_LEN];
+    char log_path[MAX_PATH_LEN];
+    int syslog_ng_enabled;
+    char usb_mount_point[MAX_PATH_LEN];
+} usb_log_config_t;
+
+// File operation context
+typedef struct {
+    char source_path[MAX_PATH_LEN];
+    char destination_path[MAX_PATH_LEN];
+    char temp_directory[MAX_PATH_LEN];
+    char archive_filename[MAX_FILENAME_LEN];
+} usb_log_file_context_t;
+
+// Error codes enumeration
+typedef enum {
+    USB_LOG_SUCCESS = 0,
+    USB_LOG_ERROR_INVALID_ARGS = 4,
+    USB_LOG_ERROR_USB_NOT_MOUNTED = 2,
+    USB_LOG_ERROR_WRITE_FAILED = 3,
+    USB_LOG_ERROR_UNSUPPORTED_DEVICE = 1,
+    USB_LOG_ERROR_MEMORY_ALLOCATION = 5,
+    USB_LOG_ERROR_CONFIG_LOAD = 6,
+    USB_LOG_ERROR_SYSTEM_COMMAND = 7
+} usb_log_error_t;
+```
+
+### 4.2 Constants and Limits
+
+```c
+#define MAX_PATH_LEN 512
+#define MAX_FILENAME_LEN 256
+#define MAX_DEVICE_NAME_LEN 32
+#define MAX_MAC_ADDRESS_LEN 18
+#define MAX_TIMESTAMP_LEN 32
+#define MAX_COMMAND_LEN 1024
+#define MAX_OUTPUT_BUFFER_SIZE 4096
+#define TEMP_DIR_PREFIX "/opt/tmpusb/"
+```
+
+**Temporary directory requirements**
+
+- `TEMP_DIR_PREFIX` defines the base directory used for staging temporary log files prior to archival.
+- The implementation MUST, before first use:
+  - Verify that the directory indicated by `TEMP_DIR_PREFIX` exists (e.g. using `stat(2)` or equivalent).
+  - Verify that the directory is writable by the usb-log-upload process.
+- If the directory does not exist, the implementation MUST attempt to create it (e.g. with `mkdir(2)`) using secure permissions (owner‑only access, such as mode `0700`, or a platform‑appropriate configurable mode).
+- If directory creation fails, or if the directory is not writable, the implementation MUST:
+  - Log an appropriate error message, and
+  - Abort the current operation and return an error (e.g. `USB_LOG_ERROR_WRITE_FAILED`) instead of proceeding with log movement or archive creation.
+- Deployment-related documentation (either a dedicated deployment section within this HLD or a separately maintained deployment guide explicitly referenced by this HLD) MUST specify which user/service account runs the usb log upload binary and ensure that it has the necessary permissions on `TEMP_DIR_PREFIX`.

+## 6. Key Algorithms
+
+### 6.1 Archive Name Generation Algorithm
+```
+ALGORITHM: generate_archive_filename()
+INPUT: None (uses system resources)
+OUTPUT: Formatted filename string
+
+1. GET mac_address FROM system utility
+2. GET current_timestamp WITH format "MM-DD-YY-hh-mmAM/PM" (e.g., "07-21-24-09-30PM")
+3. CONSTRUCT filename = mac_address + "_Logs_" + timestamp + ".tgz"
+4. RETURN filename
+```
+
+### 6.2 File Movement Algorithm
+```
+ALGORITHM: move_log_files(source_path, dest_path)
+INPUT: source_path, dest_path
+OUTPUT: Operation status
+
+1. VALIDATE source_path exists
+2. VALIDATE dest_path is writable
+3. FOR each file in source_path:
+   a. COPY file to dest_path
+   b. VERIFY copy successful
+   c. DELETE source file
+4. RETURN success/failure status
+```
+
+### 6.3 Compression Algorithm
+```
+ALGORITHM: create_log_archive(source_dir, archive_path)
+INPUT: source_directory, output_archive_path
+OUTPUT: Compression status
+
+1. VALIDATE source_directory contains files
+2. CONSTRUCT tar command with compression flags
+3. EXECUTE tar command via system interface
+4. VERIFY archive created successfully
+5. VALIDATE archive integrity
+6. RETURN status
+```
+
+## 7. Interface Definitions
+
+### 7.1 Public API Interface
+```c
+// Main interface functions
+int usb_log_upload_execute(const char *usb_mount_point);
+int usb_log_validate_prerequisites(void);
+void usb_log_cleanup_resources(void);
+
+// Configuration interface
+int usb_log_load_config(usb_log_config_t *config);
+int usb_log_get_property(const char *name, char *value, size_t value_size);
+
+// File operation interface

+
+// System interface
+int usb_log_execute_command(const char *command, char *output, size_t output_size);
+int usb_log_reload_service(const char *service_name);
+```
+
+### 7.2 Internal Module Interfaces
+```c
+// Validation module interface
+typedef struct {
+    int (*validate_device)(void);
+    int (*validate_usb_mount)(const char *mount_point);
+    int (*validate_permissions)(const char *path);
+} usb_log_validation_interface_t;
+
+// File manager interface
+typedef struct {
+    int (*create_directory)(const char *path);
+    int (*move_files)(const char *source, const char *dest);
+    int (*cleanup_files)(const char *path);
+} usb_log_file_interface_t;
+```
+
+## 8. Error Handling Strategy
+
+### 8.1 Error Classification
+- **Fatal Errors**: System-level failures requiring immediate exit
+- **Recoverable Errors**: Operation-specific failures with retry capability
+- **Warning Conditions**: Non-critical issues logged but operation continues
+
+### 8.2 Error Recovery Mechanisms
+- **Graceful Degradation**: Continue with limited functionality when possible
+- **Resource Cleanup**: Ensure all allocated resources are properly freed
+- **State Restoration**: Revert system state changes on critical failures
+
+### 8.3 Logging Strategy
+- **Structured Logging**: Consistent log message format
+- **Log Levels**: INFO, WARNING, ERROR, DEBUG

+# USB Log Upload - Requirements Document
+
+## Overview
+This document outlines the functional requirements for migrating the `usbLogUpload.sh` shell script to C code for embedded systems deployment.
+
+## Functional Requirements
+
+### Core Functionality
+1. **USB Log Transfer**: Transfer system logs from embedded device to external USB storage
+2. **Device Validation**: Verify device compatibility (currently TV devices only)
+3. **Log Archival**: Create compressed archive (.tgz) of log files with proper naming convention
+4. **Log Management**: Move logs from system location to USB, reload logging service
+
+### Inputs
+- **Primary Input**: USB mount point path (command line argument)
+- **Configuration Files**:
+  - `/etc/include.properties` - System include properties
+  - `/etc/device.properties` - Device-specific properties
+- **Environment Variables**:
+  - `DEVICE_NAME` - Device type identifier
+  - `RDK_PATH` - RDK library path (default: /lib/rdk)
+  - `LOG_PATH` - System log directory path
+  - `SYSLOG_NG_ENABLED` - Syslog-ng service status
+
+### Outputs
+- **Success Cases**:
+  - Compressed log archive on USB: `<MAC>_Logs_<timestamp>.tgz`
+  - Updated system log with operation status
+  - Exit code 0 on success
+- **Error Cases**:
+  - Exit code 2: USB not mounted
+  - Exit code 3: Writing error to USB
+  - Exit code 4: Invalid usage or unsupported device
+
+### Dependencies
+
+#### External Commands
+- `getMacAddressOnly` - MAC address retrieval utility
+- `/bin/timestamp` - Timestamp generation utility
+- `date` - Date/time formatting
+- `tar` - Archive creation
+- `killall` - Process signal management
+- `sync` - Filesystem synchronization
+
+#### System Services
+- `syslog-ng` - Logging service (if enabled)
+
+#### File System Operations
+- Directory creation and validation
+- File movement and copying
+- Archive compression
+- Temporary directory management
+
+### Constraints
+
+#### Memory Constraints
+- Must operate within embedded system memory limitations (few KBs to few MBs)
+- Minimize memory allocation during operation
+- Use fixed-size buffers where possible
+
+#### Performance Constraints
+- Real-time operation not critical but should be responsive
+- Minimize CPU usage during log compression
+- Efficient file I/O operations
+
+#### Storage Constraints
+- Handle varying USB storage capacities
+- Manage temporary directory space usage
+- Clean up temporary files after operation
+
+#### Platform Constraints
+- Must be portable across multiple embedded architectures
+- Cross-compilation support required
+- No dynamic memory allocation where avoidable
+
+### Edge Cases and Error Handling
+
+#### Input Validation
+1. **Missing Arguments**: Handle missing USB mount point argument
+2. **Invalid Path**: Validate USB mount point exists and is accessible
+3. **Device Compatibility**: Verify device type matches supported devices
+
+#### File System Errors
+1. **USB Not Mounted**: Detect and report when USB storage is not available
+2. **Insufficient Space**: Handle cases where USB has insufficient space
+3. **Permission Errors**: Handle file system permission issues
+4. **Corrupted Files**: Detect and handle corrupted log files
+
+#### Service Management Errors
+1. **Syslog-ng Reload**: Handle cases where service reload fails
+2. **Log Path Issues**: Handle missing or inaccessible log directories
+
+#### Resource Management
+1. **Memory Exhaustion**: Handle low memory conditions gracefully
+2. **Disk Full**: Handle temporary directory space exhaustion
+3. **Process Limits**: Handle system process limitations
+
+### Security Considerations
+1. **Path Traversal**: Validate all file paths to prevent directory traversal attacks
+2. **Input Sanitization**: Sanitize all user inputs and file names
+3. **Privilege Management**: Run with minimum required privileges
+4. **Temporary File Security**: Secure temporary file creation and cleanup
+
+### Compatibility Requirements
+1. **Architecture Support**: Support multiple embedded architectures
+2. **Compiler Support**: Compatible with GCC and Clang compilers
+3. **Library Dependencies**: Minimize external library dependencies
+4. **Standard Compliance**: Follow POSIX standards where applicable
+
+### Logging and Monitoring
+1. **Operation Logging**: Log all major operations to system log
+2. **Error Reporting**: Clear error messages for troubleshooting
+3. **Progress Tracking**: Status updates during long operations
+4. **Debug Information**: Configurable debug output levels

+# usbLogUpload Module
+
+## Overview
+
+`usbLogUpload` is the USB export utility in DCM Agent that copies current device logs to an attached USB storage device as a compressed archive. It replaces the legacy `usbLogUpload.sh` script with a C implementation optimized for embedded systems and intentionally reuses shared helpers from `uploadstblogs` for archive naming, MAC address resolution, and archive creation.
+
+The module is implemented as a standalone binary, `usblogupload`, with a simple single-argument interface:
+
+```bash
+usblogupload <USB_mount_point>
+```
+
+Its runtime model is deliberately simple: validate arguments and device type, validate USB availability, collect the current logs into a temporary directory, generate a `<MAC>_Logs_<timestamp>.tgz` archive on the USB device, reload `syslog-ng` when applicable, clean up temporary files, and sync the filesystem.

+
+### Runtime Directory Behavior
+
+| Path | Use |
+|------|-----|
+| `LOG_PATH` | source log directory, default `/opt/logs` |
+| `<USB_mount_point>/Log` | destination folder on USB |
+| `/opt/tmpusb/<archive_base>` | temporary staging directory |
+
+---
+
+## API Reference
+
+### `usb_log_upload_execute()`
+
+Runs the complete USB log export workflow.
+
+**Signature**
+
+```c
+int usb_log_upload_execute(const char *usb_mount_point);
+```
+
+**Parameters**
+
+- `usb_mount_point`: mount path of the attached USB device
+
+**Returns**
+
+- `0` on success
+- `2` if the USB is not mounted or invalid
+- `3` on write/archive/temporary-directory failures
+- `4` on invalid usage or unsupported device
+
+### `validate_usb_mount_point()`
+
+**Signature**
+
+```c
+int validate_usb_mount_point(const char *mount_point);
+```
+
+Ensures the caller-supplied path exists and is accessible.
+
+### `create_usb_log_directory()`
+
+**Signature**
+
+```c
+int create_usb_log_directory(const char *usb_path);
+```
+
+Creates the USB-side `Log` directory if it does not already exist.
+
+### `create_usb_log_archive()`
+
+**Signature**
+
+```c
+int create_usb_log_archive(const char *source_dir,
+                           const char *archive_path,
+                           const char *mac_address);
+```
+
+Packages staged logs into a compressed archive on USB storage.
+
+---
+
+## Shared Code Reuse
+
+`usbLogUpload` intentionally depends on `uploadstblogs` instead of reimplementing archive and naming logic.
+
+### Reused Interfaces
+
+| Shared Module | Reused Functionality |
+|---------------|----------------------|
+| `uploadstblogs/archive_manager.h` | `generate_archive_name()`, `create_archive()` (`get_archive_size()` is available in `uploadstblogs` but is not used by `usbLogUpload`) |
+| `uploadstblogs/context_manager.h` | `get_mac_address()` |
+| `uploadstblogs/file_operations.h` | directory/file helpers used by USB file manager |
+
+This reduces duplicate code and keeps archive naming aligned across upload channels.
+
+---
+
+## Usage Example
+
+### Command-Line Usage
+
+```bash
+usblogupload /mnt/usb
+```
+
+### Successful Output
+
+On success the program prints the full path of the generated archive:
+
+```text
+/mnt/usb/Log/001122334455_Logs_04_03_26_09_14_33.tgz
+```
+
+### Example Archive Naming Rule
+
+Archive names follow the shared format:
+
+```text
+<MAC>_Logs_<timestamp>.tgz
+```
+
+---
+
+## Threading Model
+
+`usbLogUpload` is single-threaded.
+
+| Aspect | Behavior |
+|--------|----------|
+| Worker threads | None |
+| Parallel operations | None |
+| Synchronization primitives | None required |
+| Concurrency assumptions | One invocation per process |
+
+Any cross-process concurrency concerns are delegated to the filesystem and the caller environment rather than internal locks.
+
+---
+
+## Memory Management
+
+The module is designed with fixed-size local buffers and minimal runtime allocation.
+
+### Primary Runtime Buffers
+
+From `usb_log_main.c`:
+
+| Buffer | Approx Size | Purpose |
+|--------|-------------|---------|
+| `usb_log_dir` | 512 B | destination USB log folder |
+| `mac_address` | 32 B | device MAC string |
+| `file_name` | 256 B | archive basename without `.tgz` |
+| `log_file` | 256 B | archive filename |
+| `temp_dir` | 512 B | temp staging directory |
+| `archive_path` | 1024 B | final archive path on USB |
+| `log_path` | 256 B | source log directory |
+| `timestamp_buf` | 32 B | human-readable logging timestamp |
+
+### Allocation Pattern
+
+```mermaid
+graph TD
+    A[main stack buffers] --> B[create temp dir]
+    B --> C[move files into temp dir]
+    C --> D[create .tgz on USB]
+    D --> E[cleanup temp dir]
+    E --> F[sync filesystem]
+```
+
+There is no complex ownership model. The main function owns the stack buffers, and temporary filesystem artifacts are cleaned before exit.
+
+---
+
+## Build Instructions
+
+### Output
+
+| Binary | Installed Name |
+|--------|----------------|
+| USB log upload utility | `usblogupload` |
+
+### Build Dependencies
+
+From `usbLogUpload/Makefile.am`, the module links against:
+
+- `libuploadstblogs.la`
+- `librdkloggers`
+- `ldwnlutil`
+- `lfwutils`
+- `lz`
+- `lpthread`
+
+### Common Build Steps
+
+```bash
+autoreconf -i
+./configure
+make
+make install
+```
+
+### Compile Flags
+
+| Flag | Purpose |
+|------|---------|
+| `-DRDK_LOGGER_EXT` | enables RDK logger integration |
+| `-Wall -Wextra -std=c99` | baseline warning and C dialect enforcement |
+
+---
+
+## Testing
+
+This module is part of the repository test and build flow. The primary behaviors to validate are:
+
+- invalid argument handling
+- unsupported-device rejection
+- USB mount validation
+- temp directory creation failure handling
+- log movement failure handling
+- archive creation failure handling
+- cleanup and sync behavior on both success and failure
+
+When run in CI, it also benefits from shared helper coverage provided by the `uploadstblogs` unit tests because archive naming and creation are reused from that module.
+
+---
+
+## Configuration and Inputs
+
+### Inputs
+
+| Source | Purpose |
+|--------|---------|
+| command line argument | USB mount point |
+| `/etc/include.properties` | provides `LOG_PATH` |
+| `/etc/device.properties` | provides `RDK_PROFILE` and `SYSLOG_NG_ENABLED` |
+
+### Defaults
+
+| Setting | Default |
+|---------|---------|
+| `LOG_PATH` | `/opt/logs` |
+
+### Outputs
+
+| Output | Description |
+|--------|-------------|
+| USB archive | compressed log bundle under `<USB>/Log/` |
+| standard output | full archive path |
+| RDK logs | execution progress and failure details |
+
+---
+
+## Exit Codes and Error Handling
+
+The public exit codes are defined in `include/usb_log_main.h`.
+
+| Code | Symbol | Meaning |
+|------|--------|---------|
+| `0` | `USB_LOG_SUCCESS` | completed successfully |
+| `1` | `USB_LOG_ERROR_GENERAL` | general internal failure |
+| `2` | `USB_LOG_ERROR_USB_NOT_MOUNTED` | USB missing or not accessible |
+| `3` | `USB_LOG_ERROR_WRITE_ERROR` | write, temp-dir, or archive failure |
+| `4` | `USB_LOG_ERROR_INVALID_USAGE` | bad CLI usage or unsupported device |
+
+### Failure Handling Rules
+
+| Failure | Behavior |
+|---------|----------|
+| logging init fails | fatal at startup |
+| bad CLI usage | immediate exit with code `4` |
+| unsupported device | immediate exit with code `4` |
+| invalid USB mount | immediate exit with code `2` |
+| temp directory failure | exit with code `3` |
+| move/archive failure | cleanup temp files and exit with code `3` |
+| syslog reload failure | logged; workflow continues |
+
+The module attempts to keep partial state minimal by cleaning the temporary directory before returning from write-path failures.
+
+---
+
+## Platform Notes
+
+- supports embedded Linux targets built with Autotools
+- device compatibility is currently checked using `/etc/device.properties`, where `RDK_PROFILE` must be `TV`
+- depends on POSIX filesystem semantics and standard utilities such as `sync`
+- keeps the runtime simple to minimize CPU and memory pressure during USB export
