+# PR_26175_DELTA_008-replay-clone-service-tests
+
+## Summary
+
+Team Delta moved `ReplayTimeline` clone operations onto the shared runtime clone helper and added replay service tests for the no-`structuredClone` fallback path.
+
+The replay model and replay system already used `cloneRuntimeValue(...)`; this PR finishes the timeline surface so replay snapshots, returned entries, and replacement frames use the same shared clone behavior.
+
+## Scope
+
+- Team: Delta
+- Branch: `PR_26175_DELTA_008-replay-clone-service-tests`
+- Runtime file changed: `src/engine/replay/ReplayTimeline.js`
+- Test file changed: `tests/replay/ReplayTimeline.test.mjs`
+- Service test command added: `npm run test:service:replay-clone`
+- Site-wide command preserved: `npm test`
+
+## Runtime Impact
+
+PASS - Replay timeline cloning remains backward compatible and now works when `structuredClone` is unavailable.
+
+## Requirement Checklist
+
+| Requirement | Status | Notes |
+|---|---|---|
+| One PR purpose only | PASS | Replay clone service testability only. |
+| Team Delta ownership only | PASS | Replay runtime and shared runtime test coverage are Delta-owned. |
+| No team-specific test runner | PASS | No Delta-named runner or command added. |
+| No `scripts/run-delta-runtime-validation.mjs` | PASS | File was not added. |
+| No `test:delta-runtime` | PASS | Script was not added. |
+| Testing organized by service/page level | PASS | Added `test:service:replay-clone`. |
+| Keep `npm test` as site-wide command | PASS | Existing `npm test` is unchanged. |
+| No UI changes | PASS | No UI files changed. |
+| No browser-owned product data | PASS | Replay tests use in-memory runtime snapshots only. |
+| No silent fallbacks or hidden defaults | PASS | Fallback clone path is explicit through `cloneRuntimeValue(...)`. |
+
+## Validation Lane Report
+
+| Command | Status | Notes |
+|---|---|---|
+| `node --check src/engine/replay/ReplayTimeline.js` | PASS | Replay timeline syntax valid. |
+| `node --check tests/replay/ReplayTimeline.test.mjs` | PASS | Replay test syntax valid. |
+| `npm run test:service:replay-clone` | PASS | 2 targeted replay test files passed. |
+| `git diff --check` | PASS | No whitespace errors before report generation. |
+| `npm run codex:review-artifacts` | PASS | Regenerated `codex_review.diff` and `codex_changed_files.txt`. |
+
+## Manual Validation Notes
+
+- Confirmed `ReplayTimeline` no longer calls `structuredClone` directly.
+- Confirmed returned timeline entries are cloned and cannot mutate stored snapshots.
+- Confirmed replacement snapshots are cloned before storage.
+- Playwright was not run; this is Node replay service coverage.

+Expected repo-structured delta ZIP:
