Scope protocol CI checks by affected binding

[kiftio]

What changes are you making?

Make protocol triggers a bit more granular.

---

I felt like we ran a lot of unnecessary checks here for a protocol-ts only change (i.e. we ran native android/swift checks).

In retrospect, as ts includes quicktype, it was probably correct to run all tests. However, there's still potential for improvement, where swift protocol changes should not build android and vice-versa

The second and third rows are the main ones of interest.

---

Implementation

Uses these filters from .ci/changed-file-filters.yml:

• protocolKotlin - (existing) generated Kotlin protocol bindings under protocol/languages/kotlin/**
• protocolSwift - (existing) generated Swift protocol bindings under protocol/languages/swift/**
• protocolTypescript - (existing) generated TypeScript protocol bindings under protocol/languages/typescript/**
• protocolShared - (new) schemas, service definitions, source-lock updates, code generators, and Protocol Node tooling

The CI workflow, package-size workflow, and E2E matrix now consume the appropriate language-specific or shared filter rather than using the broad protocol filter.

Shared inputs remain conservative: they trigger all affected platform validation because they can change generated bindings or the tooling that produces and validates them. The optimization is limited to generated language-binding changes, which now run only the checks for their actual consumers.

How to test

• Verify the new filter unit tests pass in scripts/test/changed_file_filters_test.rb, covering that protocol/package.json matches only protocolTooling and that protocol/schemas/ucp.json matches only protocolShared.
• Verify the new e2e matrix test passes in e2e/test/e2e_matrix_to_browserstack_run_plan_test.rb, confirming that a change to protocol/schemas/ucp.json selects all four applications.

Before you merge

Important

• I've added tests to support my implementation
• I have read and agree with the Contribution Guidelines
• I have read and agree with the Code of Conduct
• I've updated the relevant platform README (platforms/swift/README.md and/or platforms/android/README.md)

Releasing a new Swift version?

• I have bumped the version in ShopifyCheckoutKit.podspec
• I have bumped the version in platforms/swift/Sources/ShopifyCheckoutKit/ShopifyCheckoutKit.swift
• I have updated the SwiftPM/CocoaPods version snippets in platforms/swift/README.md (major version only)

Releasing a new Embedded Checkout Protocol version?

• I have bumped embeddedCheckoutProtocolAndroid in platforms/android/gradle/libs.versions.toml
• I have updated protocol/languages/kotlin/embedded-checkout-protocol/api/embedded-checkout-protocol.api if the public API changed

Releasing a new Android version?

• I have bumped checkoutKitAndroid in platforms/android/gradle/libs.versions.toml
• I have updated the Gradle/Maven version snippets in platforms/android/README.md

Tip

See the Contributing documentation for the full release process per platform.

[kiftio]

main diff is here,

moving form protocol to protocolKotlin || protocolShared

to avoid building for protocolSwift changes

and down below in the same way for swift

(and the same in package-size.yml)
