Roadmap: Testing System + Auto Version Bump + Toolchain Management

Progress

• Research — survey industry approaches (Conan, vcpkg, Nix, etc.)
• Design — finalize architecture and DSL decisions
• Implementation — build and ship

---

1. Testing System

• Research
• Design
  • onTest callback DSL
  • test file layout convention
  • matrix / incremental strategy
  • CI integration plan
• Implementation
  • Add onTest to ModuleF and formula DSL
  • Implement llar test command
  • CI: PR fast gate
  • CI: pre-release gate
  • CI: stable channel gate

2. Auto Version Bump

• Research
• Design
  • checked-versions.json schema
  • two-stage filtering strategy (Compare API + AI fallback)
  • cache / storage plan
• Implementation
  • llar check-versions command
  • GitHub Actions cron workflow
  • actions/cache integration
  • GitHub Compare API pre-check
  • AI agent integration (write-formula skill)

3. Toolchain Management

• Research
• Design
  • deps.needTool DSL
  • bootstrap / chicken-and-egg strategy
• Implementation
  • version-check-only mode
  • full llar-managed tool installation
  • formulas for common build tools (cmake, ninja, pkg-config, ...)
