Platform/Backend Scope: All platforms (production-readiness infrastructure)

Overview

A gap analysis targeting the distance between "feature-rich engine" and "engine you can ship games with," followed by implementation of 13 production-infrastructure systems plus 3 bonus systems. The focus is shipping concerns: packaging, asset validation, format versioning, accessibility, cross-platform input, performance regression testing, project templates, telemetry, achievements, shader hot-reload, and community contribution files.

New Systems Implemented (13 + 3 Bonus)

All systems are present in the current tree (verified 2026-06-08).

Path note (2026-06-08): A GamePackager.h exists both at Core/GamePackager.h (original) and at Engine/Build/GamePackager.h. Confirm which is canonical before extending packaging code.

CLI Extensions

spark-cli supports package, validate, migrate, and templates subcommands.

Key Patterns Used

• New systems follow the singleton pattern with GetInstance().
• Header-only implementations, consistent with many existing systems.
• Console_GetStatus() for debug output.
• Doxygen comments on all public APIs.
• Each system has a dedicated test file.

Context

At the time of the original analysis SparkEngine had 447K+ lines of C++, 30+ working subsystems, and ~3,119 tests, but lacked production infrastructure: no game packaging, no asset validation, no format versioning, no accessibility, limited cross-platform input, no performance regression testing, only one project template, basic UI widgets, no telemetry, undocumented achievements, no shader hot-reload, and no community contribution files. The 16 systems above close those gaps.

Source & Freshness

• Original entry date: 2026-04-04 (.claude/knowledge/project-recommendations-2026-04-04.md)
• Verified against codebase 2026-06-08.

Updates / status changes since the original:

• All 16 systems (13 + 3 bonus) still present at the stated paths — Implemented.
• New observation: a second GamePackager.h exists under Engine/Build/ alongside the original Core/GamePackager.h — flagged above to avoid duplicate-system drift.
• Test totals referenced in the original ("3311+ tests") are superseded — the suite has grown to ~6,000 tests; the per-system test files remain in place.
• No regressions or removals detected.
