Shopify Checkout Extensibility Klaviyo Silent-Install Verifier And ROAS-Recovery Sentinel Before The August 26 2026 Non-Plus Cutover
Shopify Checkout Extensibility broke Klaviyo's auto-install starting August 2025 — the integration appears installed but Active On Site reads zero, ad tracking silently fails, and merchants only notice when ROAS collapses (one DTC brand watched Meta ROAS go 4.2x to under 1x in a quarter). Non-Plus merchants face an August 26 2026 deadline that will trigger another wave of breakage. A continuous install-verifier that checks Active On Site, the 12 events Klaviyo expects, and auto-files a repair, with a ROAS-drop alert tied to tracking failures.
Lead with the alert, not the verifier. Merchants buy 'we'll text you when your ROAS drops because Klaviyo broke' faster than they buy 'continuous integration checker.' Same product, different framing. Time the launch to mid-July so you have six weeks of post-Aug-26 horror stories to point to.

Attribution vendors monitor your numbers. Klaviyo's docs monitor nothing. Nobody monitors the install itself continuously. The Aug 26 cutover guarantees a second wave of merchants with broken pixels who think their ads stopped working.
