### Step 499: Scenario - Greenfield Project
**Status:** PASS (12/12 tests)
Implements the first Phase 25b end-to-end scenario for:
"Build a URL shortener with user accounts".
**Files added:**
- `editor/src/GreenfieldScenarioRunner.h` - scenario orchestration across:
- problem parsing and layered decomposition
- stack selection with explicit preferences (`python`, `postgresql`, `typescript`)
- annotated skeleton generation + scaffold planning/materialization
- task routing (`deterministic` / `llm` / `human`) with context bundles
- security auditing over generated code surfaces
- `editor/tests/step499_test.cpp` - 12 scenario tests covering:
- decomposition + stack expectations
- annotation presence in generated skeleton functions
- deterministic auto-complete, llm context preparation, and human-review surfacing
- scaffold sidecars/workflow-state materialization on disk
- security-findings/report shape and execution notes
- `editor/CMakeLists.txt` - `step499_test` target
**Verification run:**
- `cmake --build editor/build-native --target step499_test step498_test` - PASS
- `./editor/build-native/step499_test` - PASS (12/12)
- `./editor/build-native/step498_test` - PASS (8/8) regression coverage
**Architecture gate check:**
- `editor/src/GreenfieldScenarioRunner.h` within header-size limit (`153` <= `600`)
- `editor/tests/step499_test.cpp` within test-file size guidance (`191` lines)
- Header-only architecture and naming conventions remain aligned with `ARCHITECTURE.md`
