BlockShift

A major commerce platform's newer native checkout-extension surface can displace features previously delivered by third-party checkout applications. The supplied research reports a live platform transition, many adjacent applications not yet migrated and a future deprecation milestone. It confirms a partner interface exposing subscription and historical charge events and found no reviewed migration product sold to the app-vendor side. These findings create urgency but require current platform documentation and per-app validation.

BlockShift would preserve vendor organization, application, platform version, platform deadline source, source publication time, merchant account, merchant permission, installed version, installation status, active-subscription assertion, historical billing event, recurring-revenue estimate, estimate method, contract or plan, configuration export, configuration version, feature inventory, native-feature mapping candidate, unsupported feature, merchant customization, data-handling requirement, migration priority candidate, customer-success owner, migration proposal, generated extension source, generator version, code diff, dependency, test fixture, automated test result, security review, accessibility review, merchant acceptance, vendor release approval, deployment plan, rollback plan, submitted extension, platform review state, merchant cutover, destination readback, billing transition, support incident, correction and deletion as distinct records.

Subscription and billing events do not prove future recurring revenue, churn or willingness to migrate. A generated extension can be syntactically valid while changing checkout behavior, data access, performance, accessibility or merchant branding. Native features may not be equivalent to the vendor's product, and the platform may change requirements. The product must never access merchant data beyond vendor and merchant permissions, deploy code, submit extensions, change billing or cut over merchants automatically. Revenue exposure is a scenario owned by vendor finance and customer-success leaders, not a score that ranks or pressures merchants.

The pilot should use synthetic merchant installations, public platform fixtures and sandbox extensions. The likely buyer is an app-vendor engineering, product, customer-success or finance owner, but affected vendor count, interface access, configuration diversity, migration capacity, merchant consent, testing burden, budget and willingness to use a separate cockpit remain unverified.
