 REASONING: high
 
 COMMAND:
-1. Open the roadmap at:
-   docs/dev/roadmaps/MASTER_ROADMAP_HIGH_LEVEL.md
-
-2. Execute the smallest real PR needed to complete Level 19 Track D:
-   - ensure all systems expose debug data
-
-3. Search only where needed:
-   - existing debug providers
-   - debug panels / registries
-   - rendering/input/physics/state/replay/networking runtime data surfaces
-   - focused tests validating debug exposure
-
-4. Verify debug-data exposure for:
-   - rendering
-   - input
-   - physics
-   - state/replay
-   - networking
-
-5. If any target system is missing exposure, apply the smallest valid fix:
-   - add minimal provider output or wiring
-   - add/update focused tests proving the data reaches the existing debug surface
-   - do not add new features or broad UX changes
-
-6. Run validation using the deduplicated command set:
-   - node ./scripts/run-node-tests.mjs
-   - npm run test:launch-smoke only if needed for runtime/debug coverage
-
-7. Produce reports:
-   - docs/dev/reports/BUILD_PR_LEVEL_19_15_DEBUG_OBSERVABILITY_VALIDATION_summary.md
-   - docs/dev/reports/BUILD_PR_LEVEL_19_15_DEBUG_OBSERVABILITY_VALIDATION_coverage.md
-   - docs/dev/reports/BUILD_PR_LEVEL_19_15_DEBUG_OBSERVABILITY_VALIDATION_results.md
-
-8. In the reports, record:
-   - which systems were checked
-   - what debug data each system exposes
-   - files changed
-   - commands run
-   - pass/fail results
-   - any bounded caveats
-
-9. Update the roadmap only if this PR proves the remaining Track D item:
-   - [x] ensure all systems expose debug data
-
-10. Package the repo-structured ZIP to:
-   <project folder>/tmp/BUILD_PR_LEVEL_19_15_DEBUG_OBSERVABILITY_VALIDATION.zip

+# BUILD_PR_LEVEL_19_16_TOOLCHAIN_ENGINE_INTEGRATION_VALIDATION Summary
+
+## PR Purpose
+Validate Phase 19 Track E toolchain-engine integration with a narrow execution-backed lane.
+
+## Scope Executed
+- Added one composite final gate test:
+  - `tests/final/ToolchainEngineIntegrationValidation.test.mjs`
+- Reused existing toolchain/runtime validation tests (no engine feature work):
+  - `tests/tools/ToolEntryLaunchContract.test.mjs`
+  - `tests/tools/ProjectToolDataContracts.test.mjs`
+  - `tests/tools/RuntimeAssetLoader.test.mjs`
+  - `tests/tools/RenderPipelineContractAll4Tools.test.mjs`
+  - `tests/tools/RuntimeSceneLoaderHotReload.test.mjs`
+- Wired the new final gate into `tests/run-tests.mjs`.
+
+## Outcome
+- Validation command passed:
+  - `PASS ToolchainEngineIntegrationValidation`
+- Roadmap updated status-only for the single proven Track E item:
+  - `[x] verify tools integrate cleanly with engine`
+
+## Bounded Status
+This PR intentionally does not close the remaining Track E items:
+- `validate asset pipelines end-to-end`
+- `validate editor -> runtime consistency`
+- `confirm no tool-specific logic leaks into engine`

-Scope executed (bounded overlay runtime hardening slice):
-- Audited `samples/phase-17/shared/overlayGameplayRuntime.js` for local helper duplication against existing `src/shared` surfaces.
-- Migrated duplicated finite-number normalization usage from local helper `normalizePointerNumber` to shared `asFiniteNumber` from `src/shared/number/index.js`.
-- Removed the local duplicate helper and updated all in-slice pointer/gesture/layout call sites to use the shared helper.
-- Added enforcement coverage in `tests/runtime/Phase19OverlayExpansionFramework.test.mjs` to validate the overlay runtime slice imports shared number normalization and no longer defines the local duplicate helper.
-- Updated Level 18 Track A roadmap markers only for directly advanced bounded-slice progress.
+Scope:
+- Narrow Phase 19 Track E validation lane for toolchain-engine integration.
 
-No new features were added and no unrelated runtime/game/tool areas were modified.
+What changed:
+- Added composite final gate test:
+  - tests/final/ToolchainEngineIntegrationValidation.test.mjs
+- Wired final gate into node test suite:
+  - tests/run-tests.mjs
+- Updated Track E roadmap status for the single execution-backed item:
+  - docs/dev/roadmaps/MASTER_ROADMAP_HIGH_LEVEL.md
+- Updated PR reports:
+  - docs/dev/reports/BUILD_PR_LEVEL_19_16_TOOLCHAIN_ENGINE_INTEGRATION_VALIDATION_summary.md
+  - docs/dev/reports/BUILD_PR_LEVEL_19_16_TOOLCHAIN_ENGINE_INTEGRATION_VALIDATION_coverage.md

+# BUILD_PR_LEVEL_19_16_TOOLCHAIN_ENGINE_INTEGRATION_VALIDATION
+
+## Purpose
+Close the next open Phase 19 lane by validating toolchain-to-engine integration boundaries without broadening scope.
+
+## Scope
+- Validate tool launch/entry integration against current engine/runtime expectations
+- Validate tool project/data contract alignment with runtime consumers
+- Validate asset pipeline handoff from tool outputs into runtime loading paths
+- Validate editor/runtime consistency for the targeted active tools
+- Confirm no tool-specific logic has leaked into engine paths
+
+## Non-Goals
+- No new features
+- No engine refactors unless required to remove verified tool leakage
+- No broad repo cleanup
+- No unrelated hardening outside this lane
+
+## Execution Rules
+- Codex performs all implementation, tests, and any scripts needed for this PR
+- Keep the PR narrow and testable
+- Preserve existing repo boundaries
+- Prefer existing validation patterns over inventing new frameworks
+- Roadmap updates must be status-only and execution-backed
+
+## Targeted Acceptance Criteria
+1. Tool entry/launch paths validate cleanly for the active tools in scope.
+2. Tool-authored project/data shapes validate against runtime consumers.
+3. Asset pipeline handoff is validated end-to-end for the scoped tools.
+4. Editor/runtime consistency is validated for representative flows.
+5. No tool-specific logic remains embedded in engine paths for the scoped validation lane.
+6. Validation artifacts are captured in docs/dev/reports.
+
+## Recommended Codex Work Order
+1. Inspect current tool-to-engine touchpoints for the active tools.
+2. Define the smallest executable validation surface for this lane.
+3. Implement or adjust only the minimum validation coverage needed.
+4. Fix any verified boundary leaks discovered within scope.
+5. Run the validation set and capture results.
+6. Update roadmap status only if execution proves completion.
+
+## Deliverables Expected From Codex
+- Any implementation/tests/scripts required to satisfy this PR
+- Updated validation/report outputs under docs/dev/reports
+- Status-only roadmap update if backed by execution
+- Final ZIP artifact at:
+  - `<project folder>/tmp/BUILD_PR_LEVEL_19_16_TOOLCHAIN_ENGINE_INTEGRATION_VALIDATION.zip`
