+# PR_26175_DELTA_006 Manual Validation Notes
+
+## Manual Review
+
+- Confirmed the replacement PR avoids team-specific test orchestration.
+- Confirmed no `scripts/run-delta-runtime-validation.mjs` file exists.
+- Confirmed no `test:delta-runtime` package script exists.
+- Confirmed `test:service:runtime` is organized by runtime service coverage, not team ownership.
+- Confirmed `npm test` remains the broader site-wide/all-tests command path.
+- Confirmed no UI, browser-owned product data, fake-login, MEM DB, local-mem, silent fallback, or hidden default behavior was introduced.
+
+## Manual Validation
+
+PASS - Code review found the changes scoped to package test command wiring and replay timeline clone fallback alignment.
+
+## Follow-Up
+
+- The superseded draft PR #188 should be closed only with explicit OWNER approval.

+
+| Requirement | Status | Notes |
+| --- | --- | --- |
+| Hard stop if not on `main` after checkout/pull | PASS | Work started from clean synced `main`. |
+| Do not keep/create `scripts/run-delta-runtime-validation.mjs` | PASS | File does not exist. |
+| Do not keep/create `npm run test:delta-runtime` | PASS | No package script exists. |
+| Do not create Team Delta-specific test command | PASS | Added `test:service:runtime`, a service-level command. |
+| Testing organized by page/service level | PASS | Runtime service command groups runtime/replay/API client service tests. |
+| Focused command for page/service-level tests | PASS | `npm run test:service:runtime`. |
+| One site-wide/all-tests command | PASS | Existing `npm test` remains the site-wide/all-tests Node command path. |
+| DELTA_001 through DELTA_005 covered through page/service tests | PASS | Runtime tick, replay, API client, event, trigger/action, and final systems tests run through the service command. |
+| Team Delta ownership only | PASS | Replay/runtime/API/event coverage is Delta-owned. |
+| No unrelated cleanup | PASS | Changes are limited to package command, replay clone fallback fix, reports, Codex artifacts, and ZIP. |
+| No UI changes | PASS | No UI files changed. |
+| No browser-owned product data | PASS | No browser storage/product data contract changed. |
+| No fake-login, MEM DB, local-mem, silent fallback, or hidden defaults | PASS | No auth or data source fallback changed. |
+| Required reports and ZIP | PASS | Report packet, Codex artifacts, and repo-structured ZIP are included. |
+| Recovery rebase from current main | PASS | Branch repaired on top of `main` at `7bdcdfed1`. |
+
+## Compatibility Notes
+
+- Existing `npm test` remains unchanged.
+- Existing individual test files remain directly runnable.
+- Replay timeline clone behavior now uses the same shared runtime clone helper as ReplaySystem.

+
+## Commands
+
+```powershell

+npm run test:service:runtime
+node -e "const pkg=require('./package.json'); if (pkg.scripts['test:delta-runtime']) throw new Error('team-specific delta script exists'); if (!pkg.scripts['test:service:runtime']) throw new Error('service runtime script missing'); if (!pkg.scripts.test) throw new Error('site-wide test script missing'); console.log('service runtime and site-wide test commands present');"
+if (Test-Path scripts/run-delta-runtime-validation.mjs) { Write-Error 'unexpected delta runtime script'; exit 1 } else { Write-Output 'no delta runtime script present' }
+rg -n "delta-runtime|run-delta-runtime|test:delta|Team Delta-specific|Delta validation harness" package.json scripts src/engine/replay
+git diff --check
+```
+
+## Results
+
+| Command | Status |
+| --- | --- |
+| `node --check src/engine/replay/ReplayTimeline.js` | PASS |
+| `npm run test:service:runtime` | PASS - 7/7 targeted Node test files passed after rebase. |
+| Package command assertion | PASS |
+| Delta harness file absence check | PASS |
+| Team-specific command grep | PASS - no matches in package scripts, scripts, or replay source. |
+| `git diff --check` | PASS |
+
+## Runtime Service Coverage
+
+`npm run test:service:runtime` passed seven targeted test files:
+
+- `tests/engine/RuntimeTickLoop.test.mjs`
+- `tests/replay/ReplaySystem.test.mjs`
+- `tests/dev-runtime/ServerApiClientStandardization.test.mjs`
+- `tests/engine/RuntimeEventSystem.test.mjs`
+- `tests/engine/RuntimeTriggerProcessing.test.mjs`
+- `tests/engine/RuntimeActionSystem.test.mjs`
+- `tests/final/FinalSystems.test.mjs`
+
+## Site-Wide Command
+
+PRESENT - `npm test` remains the site-wide/all-tests Node command path.
+
+## Browser Validation
+
+SKIP - No browser UI files changed.
+
+## Playwright Validation
+
+SKIP - Runtime service coverage is Node-based and no page UI changed.

+# PR_26175_DELTA_006-page-service-test-lanes
+
+## Summary
+
+Team Delta replaced the team-specific validation harness approach with a project testing direction based on page/service-level commands.
+
+This PR adds `npm run test:service:runtime` as the focused runtime service test command. It uses the existing `scripts/run-node-test-files.mjs` runner and does not add a Team Delta-specific script, package command, or test orchestration layer.
+
+The service command exposed a replay service testability gap: `ReplayTimeline` still depended directly on native `structuredClone`, so the replay fallback behavior from prior runtime clone work could not be validated through the service-level lane. `ReplayTimeline` now uses the existing shared `cloneRuntimeValue(...)` helper.
+
+## Command Model
+
+| Need | Command | Status |
+| --- | --- | --- |
+| Focused runtime service validation | `npm run test:service:runtime` | PASS |
+| Site-wide/all-tests command path | `npm test` | PRESENT |
+
+## DELTA_001 Through DELTA_005 Coverage
+
+| Prior runtime behavior | Service-level coverage |
+| --- | --- |
+| DELTA_001 runtime tick optimization | `tests/engine/RuntimeTickLoop.test.mjs` |
+| DELTA_002 replay clone consolidation | `tests/replay/ReplaySystem.test.mjs` |
+| DELTA_003 API client standardization | `tests/dev-runtime/ServerApiClientStandardization.test.mjs` |
+| DELTA_004 runtime event test coverage | `tests/engine/RuntimeEventSystem.test.mjs` |
+| DELTA_005 runtime event clone cleanup | `tests/engine/RuntimeTriggerProcessing.test.mjs`, `tests/engine/RuntimeActionSystem.test.mjs`, `tests/final/FinalSystems.test.mjs` |
+
+## Scope
+
+- Team: Delta
+- Runtime service command changed: `package.json`
+- Runtime service implementation changed: `src/engine/replay/ReplayTimeline.js`
+- Runtime code ownership: Replay/runtime clone behavior is Team Delta-owned.
+- UI changed: none
+- Browser-owned product data changed: none
+- Team-specific test command added: no
+
+## Replacement Notes
+
+PASS - This replacement PR does not keep or create:
+
+- `scripts/run-delta-runtime-validation.mjs`
+- `npm run test:delta-runtime`
+- Team Delta-specific test commands
+
+## Backlog Update
+
+SKIP - This is an OWNER-directed replacement for the draft harness approach and does not change backlog source-of-truth status.
+
+## Tool State Update
+
+SKIP - No Build Path tool status or tool tile state changed.
+
+## Validation Summary
+
+PASS - Runtime service validation passed through `npm run test:service:runtime`.
+
+See `PR_26175_DELTA_006-page-service-test-lanes-validation.md` for command details.
+
+## Branch Disposition
+
+Source branch should be retained after merge unless OWNER later approves branch deletion.
