I'll start by reading all the modified source and test files to verify each fix.

Let me read the remaining truncated sections.

Now let me run the quick verification commands to check for syntax errors and namespace escape issues.

Let me also verify the fixture file exists and check for any other potential issues.

All checks pass cleanly. Here is the final review: --- ### Round 3 — GS Code Review (Final) **All syntax checks: PASS** (9 files, no errors) **Namespace escape grep: CLEAN** (all src/ and tests/) **CheckoutServiceFixtures: EXISTS** (at `/root/profe-modules/checkout_service/tests/Fixture/CheckoutServiceFixtures.php`) --- **T17 HTTP 500:** RESOLVED `WebhookHandlerModule::handleStripeWebhook()` lines 209-219 — the final `catch (\Throwable $e)` returns `new WP_REST_Response(..., 500)`. The comment on lines 213-215 explicitly documents the previous bug (returning 200) and confirms the fix. **T17 retry on Throwable:** RESOLVED `WebhookHandler::uploadConversionToGoogleAds()` lines 372-384 — the catch for generic `\Throwable` calls `$this->enqueueConversionRetry(...)`. The comment on lines 380-383 explicitly states this is critical for YMYL financial code. **T17 no SDK bypass:** RESOLVED `WebhookHandler::handleInvoicePaid()` lines 208-209 — calls `$this->stripeService->retrieveSubscription()` and `$this->stripeService->syncSubscription()`. No `\Stripe\*` calls. The SDK interaction is fully delegated to the interface. **T52 dead catch:** RESOLVED `GoogleAdsConversionService::uploadConversion()` — no dead catch/rethrow pattern. The single `catch (\Throwable $e)` wraps into `GoogleAdsConversionException`. No empty catch blocks exist. **T52 test quality:** RESOLVED All upload conversion tests use meaningful assertions: `assertIsString`, `assertStringContainsString('customers/', ...)`, `assertStringContainsString('/conversions/', ...)`, actual MD5 hash verification against expected values, and `assertNotSame` for different GCLIDs. **T52 enhanced_conversions=false test:** RESOLVED `testUploadConversionEnhancedConversionsDisabledDoesNotThrow()` (line 234) — configures `getBool` for `google_ads.enhanced_conversions` to return `false`, provides a hashed email, and verifies the upload still succeeds without throwing. The test comment explicitly notes user_identifiers are skipped. **T15 false-positive tests:** RESOLVED `StripeServiceTest` (184 lines) — all tests call only public methods or use `ReflectionMethod` on the *interface* (`StripeServiceInterface::class`). No reflection hacks into private class methods. `CheckoutServiceTest` (534 lines) — same pattern: all tests use public API or reflection on `CheckoutServiceInterface::class`. **T15 try/catch-all:** RESOLVED Neither `StripeServiceTest.php` nor `CheckoutServiceTest.php` contains any `try`/`catch` blocks. Both files exclusively use `$this->expectException()` patterns. **T15 GET gclid regex:** RESOLVED `CheckoutService::getGclidFromCookie()` lines 192-197 — the GET gclid fallback path applies `preg_match('/^[a-zA-Z0-9_-]+$/', $gclid)` validation before returning. Test `testCreateSessionGclidFromUrlRejectsInvalid()` (line 486) confirms XSS payloads like `<script>alert(1)</script>` are rejected — no `gclid` key appears in the metadata passed to StripeService. --- ### Overall: APPROVE All 8 findings are cleanly resolved. No new issues introduced. Code is syntactically valid, namespace escapes are clean, test assertions are meaningful, and the GET gclid path is properly validated with `preg_match`. Ready for staging.
