Frontend: - Integrated fleet management API (registration modal, status indicators, and deletion). - Added CSV export functionality across the dashboard, alerts, and anomalies pages. Firmware (C/C++): - Implemented EvidenceStore utilizing a circular buffer to preserve up to 32 EvidenceSnapshot records. - Added FNV-1a hash chain verification to ensure data integrity and enable tamper detection. - Introduced 8 new unit tests for the evidence preservation logic. CI & Documentation: - Added 'backend-test' job (Python 3.11, pytest) to the CI pipeline, bringing the total to 7 jobs. - Updated ROADMAP.md and CHANGELOG.md to reflect v3.2.0 completion.

Review Process - -- Maintainers will review your PR -- Address feedback with new commits (don't force-push during review) -- Once approved, maintainer will merge (squash merge preferred) - -## Coding Standards - -### C++17 Compliance - -- **Standard**: C++17 (no C++20/23 features) -- **Compatibility**: Must compile on GCC 7+, Clang 5+, MSVC 2017+ -- **No exceptions**: Use `Result` monad for error handling - -### Style Guide - -#### Naming Conventions - -```cpp -// Classes, Structs, Enums: PascalCase -class GridShieldSystem { }; -struct TamperConfig { }; -enum class ErrorCode { }; - -// Functions, Variables: snake_case -void initialize_system(); -uint32_t packet_count; - -// Constants, Macros: UPPER_SNAKE_CASE -constexpr size_t MAX_BUFFER_SIZE = 512; -#define GS_MAKE_ERROR(code) ... - -// Namespaces: lowercase -namespace gridshield::core { } -``` - -#### File Organization - -```cpp -// Header (.hpp) -#pragma once - -#include "dependencies.hpp" // External first -#include "core/types.hpp" // Internal after - -namespace gridshield { -namespace module { - -class MyClass { -public: - // Public interface first - MyClass() noexcept; - void public_method() noexcept; - -private: - // Private implementation - void private_helper() noexcept; - int member_variable_; -}; - -} // namespace module -} // namespace gridshield -``` - -#### Formatting - -- **Indentation**: 4 spaces (no tabs) -- **Line Length**: 100 characters max -- **Braces**: Allman style for functions, K&R for control flow - ```cpp - void function() // Allman - { - if (condition) { // K&R - // code - } - } - ``` -- **Spacing**: Space after keywords, around operators - ```cpp - if (x == y) { } // Good - if(x==y){} // Bad - ``` - -#### Best Practices - -```cpp -// Use const/constexpr where possible -constexpr size_t SIZE = 10; -void process(const Data& data) noexcept; - -// Prefer noexcept for move/destructors -MyClass(MyClass&& other) noexcept; -~MyClass() noexcept; - -// Use GS_MOVE for clarity (defined in gs_macros.hpp) -return GS_MOVE(result); - -// Check errors explicitly -auto result = operation(); -if (result.is_error()) { - return result.error(); -} - -// Comment non-obvious code -// Calculate checksum using modified FNV-1a algorithm -uint32_t checksum = compute_hash(data); -``` - -### Platform-Specific Code - -```cpp -// Use platform macros -#if GS_QEMU_BUILD - // QEMU simulation-specific code paths - ESP_LOGI(TAG, "Running in QEMU simulation"); -#else - // Production hardware code paths - ESP_LOGI(TAG, "Running on ESP32 hardware"); -#endif -``` - -### Memory Management - -```cpp -// NO heap allocation in core library -// Use StaticBuffer instead of std::vector -core::StaticBuffer buffer; - -// NO exceptions - use Result -core::Result operation() noexcept; - -// NO raw pointers for ownership - use RAII -class Resource { - ~Resource() noexcept { cleanup(); } -}; -``` - -## Commit Message Guidelines - -Follow [Conventional Commits](https://www.conventionalcommits.org/): - -``` -(): - - - -
