+# PR_26175_DELTA_010-runtime-testability-closeout
+
+## Summary
+
+Team Delta completed the report-only runtime testability closeout after PR_26175_DELTA_009 merged to main.
+
+This PR does not change runtime behavior, tests, package commands, UI, browser-owned data, hidden defaults, or fallback behavior. It records the final Delta testability state and confirms the page/service-level testing model is the active direction.
+
+## Scope
+
+- Team: Delta
+- Branch: `PR_26175_DELTA_010-runtime-testability-closeout`
+- Purpose: report-only closeout
+- Runtime feature changes: none
+- New tests: none
+- New npm commands: none
+- New runners: none
+- UI changes: none
+

+
+## Testing Model Confirmation
+
+| Requirement | Status | Evidence |
+|---|---|---|
+| `npm test` is the site-wide/all-tests command | PASS | `package.json` keeps `test=node ./scripts/run-node-tests.mjs`. |
+| Page/service-level testing is active | PASS | `test:service:runtime` and `test:service:api` are present. |
+| No Team Delta-specific test command exists | PASS | Package/script guard found no `test:delta-runtime`, `run-delta-runtime`, or `test:delta` command. |
+| No Team Delta validation harness exists | PASS | `scripts/run-delta-runtime-validation.mjs` is absent. |
+| No duplicate test runner/orchestration added by Delta closeout | PASS | Existing `scripts/run-node-test-files.mjs` remains the focused service-file runner. |
+
+## Runtime Testability Coverage
+
+| Area | Page/service lane coverage |
+|---|---|
+| Runtime tick and processing | `npm run test:service:runtime` |
+| Replay clone and timeline behavior | `npm run test:service:runtime` |
+| Runtime event/action/trigger systems | `npm run test:service:runtime` |
+| Final runtime systems coverage | `npm run test:service:runtime` |
+| Shared API client boundary behavior | `npm run test:service:api` |
+| Public API URL resolution | `npm run test:service:api` |
+
+## Validation
+
+| Command | Status | Notes |
+|---|---|---|
+| `npm run test:service:runtime` | PASS | 23/23 targeted Node test files passed after PR_009 merge. |
+| `npm run test:service:api` | PASS | 2/2 targeted Node test files passed. |
+| Package/script guard | PASS | `npm test` unchanged; no team-specific Delta command or harness. |
+| Report verification | PASS | Required PR_010 report files exist. |
+| `git diff --check` | PASS | No whitespace errors after report generation. |
+
+## Manual Notes
+
+- `npm test` was inspected as the site-wide command path and was not changed.
+- Full `npm test` was not required for this report-only PR because no runtime, test, or command implementation changed in PR_010.
+- Source branches are retained; no branch deletion was performed.
+- Obsolete draft Delta implementation PRs #188, #190, #192, and #193 were closed as superseded during final EOD closeout. Branches were retained.
+- Expected remaining Team Delta work: none.

++## Runtime Accomplishments
++
++- Runtime tick, replay clone, API client, runtime event, trigger/action, and final systems coverage are represented through service lanes.
++- Runtime implementation is unchanged by DELTA_010.
++- No browser-owned product data was introduced.
++- No hidden defaults or silent fallbacks were introduced.
++
++## Testing Accomplishments
++
++- `npm test` remains the single site-wide/all-tests command.
++- `npm run test:service:runtime` provides focused runtime service coverage.
++- `npm run test:service:api` provides focused API client service coverage.
++- No `test:delta-runtime` command exists.
++- No `scripts/run-delta-runtime-validation.mjs` harness exists.
++- No Team Delta-specific test runner remains.
++
++## Governance Accomplishments
++
++- Page/service-level testing is the active model.
++- Team-specific validation harness work was superseded and closed.
++- Obsolete draft Delta implementation PRs #188, #190, #192, and #193 were closed without deleting branches.
++- Source branches are retained.
