+# BUILD_PR_LEVEL_22_1_RUNTIME_MONITORING_AND_LOGGING_FOUNDATION — Error Tracking
+
+## Scope Implemented
+- Added `createRuntimeMonitoringHooks` in `src/engine/runtime/RuntimeMonitoringHooks.js` as the shared runtime error/performance hook surface.
+- Wired engine runtime monitoring lifecycle in `src/engine/core/Engine.js`:
+  - start hooks during `engine.start()`
+  - stop hooks during `engine.stop()`
+  - emit monitoring events to runtime consumers:
+    - `engine:runtime-monitoring-error`
+    - `engine:runtime-monitoring-performance`
+- Wired tools runtime monitoring in `tools/shared/platformShell.js` with the shared hook surface and tools runtime context capture.
+
+## Error Tracking Behavior
+- Captures global runtime errors when `window` is available:
+  - `window.error`
+  - `window.unhandledrejection`
+- Emits normalized payloads using `runtime.monitoring.v1`.
+- Preserves non-breaking behavior by keeping existing `engine:runtime-error` and `trackRuntimeError(...)` flow unchanged.

+# BUILD_PR_LEVEL_22_1_RUNTIME_MONITORING_AND_LOGGING_FOUNDATION — Logging Standard
+
+## Logging Baseline
+- Existing standardized logger format remains authoritative:
+  - `format: engine.log.v1`
+- This PR adds runtime monitoring event usage aligned to that format:
+  - `runtime.monitoring.error`
+  - `runtime.monitoring.performance`
+
+## Standardized Expectations
+- Every emitted logger entry includes:
+  - `format`
+  - `level`
+  - `channel`
+  - `event`
+  - `message`
+  - `meta`
+  - `timestamp`
+- Runtime monitoring payload contract is versioned separately as:
+  - `format: runtime.monitoring.v1`
+
+## Non-Breaking Guarantee
+- Existing logger behavior is unchanged.
+- Existing engine runtime error/performance events are preserved.

+# BUILD_PR_LEVEL_22_1_RUNTIME_MONITORING_AND_LOGGING_FOUNDATION — Performance Monitoring
+
+## Scope Implemented
+- Added shared runtime performance sampling via `createRuntimeMonitoringHooks(...)`.
+- Hook emits performance samples at runtime start and on configured interval.
+- Engine now starts/stops monitoring with runtime lifecycle.
+- Tools platform shell now starts/stops monitoring for tool runtime surfaces.
+
+## Monitoring Payload
+- Format: `runtime.monitoring.v1`
+- Kind: `performance`
+- Fields:
+  - `source`
+  - `reason` (`start`, `interval`, `manual`)
+  - `timestamp`
+  - `sample.nowMs`
+  - optional `sample.memory` (when available)
+  - `context`
+
+## Validation Notes
+- Targeted tests verify start sample, interval sample, and manual sample behavior.
+- Existing lifecycle validation confirms engine performance frame publication remains intact (`engine:performance-frame`).

+# BUILD_PR_LEVEL_22_1_RUNTIME_MONITORING_AND_LOGGING_FOUNDATION — Validation
+
+## Commands Run
+1. `node --input-type=module -e "import { run as runHooks } from './tests/runtime/RuntimeMonitoringHooks.test.mjs'; import { run as runLifecycle } from './tests/runtime/Phase19RuntimeLifecycleValidation.test.mjs'; runHooks(); runLifecycle(); console.log('PASS runtime monitoring + lifecycle');"`
+2. `node --input-type=module -e "import { run as runShell } from './tests/tools/PlatformShellHeaderAlignment.test.mjs'; runShell(); console.log('PASS platform shell header alignment');"`
+
+## Results
+- PASS runtime monitoring + lifecycle
+- PASS platform shell header alignment
+
+## Validation Coverage
+- Runtime hook payload contracts (`runtime.monitoring.v1`) validated.
+- Runtime lifecycle integration (engine start/stop monitoring) validated.
+- Existing runtime lifecycle and logging format behavior validated.
+- Tools shell integration change validated against existing shell alignment test surface.
+
+## Roadmap Status Handling
+- Checked `docs/dev/roadmaps/MASTER_ROADMAP_ENGINE.md` Track 20B.
+- Items were already `[x]` before this PR:
+  - runtime error tracking
+  - performance monitoring hooks
+  - logging standardization
+- No roadmap text rewrite performed.
+- No non-status roadmap edits performed.
+
+## Scope Confirmation
+- No `start_of_day` changes.
+- No unrelated cleanup.
+- Smallest scoped implementation for runtime monitoring/logging foundation.
