Codebase Statistics

Codebase Statistics

Comprehensive metrics and analysis of the SparkEngine codebase. Updated 2026-09-03. This source inventory is not readiness evidence. The stable-v1 Windows 11 x64 profile remains blocked and uncertified in docs/site/readiness.json.

ECS Architecture Metrics

Metric	Count
Concrete component-group headers (Engine/ECS/Components/*Components.h)	17
Struct declarations in those headers	79
ECS systems	25
Execution order	Physics → Animation → AI → Audio → Lifecycle → Render

Component provenance: this declaration inventory scans only the concrete *Components.h files and matches whitespace-tolerant struct declarations. It does not measure registration, runtime use, support, or readiness.

Editor Metrics

Metric	Count
*Panel.h class inventory	65
Total editor lines	109226

Testing Metrics

Metric	Count
Test files	577
TEST() definitions	6992
Configured sanitizer workflow lanes	ASan + UBSan + LSan + TSan + MSan

Build System Metrics

Metric	Count
CMake option() declarations	30
ENABLE_* feature toggles	22
Game modules	11
SDK public headers	15
Documented build compiler paths	MSVC v143/v145, GCC 13+, Clang 17+, Apple Clang, MinGW-w64
Platforms	Windows, Linux, macOS (experimental)
