The CredentialRequestCoordinator's method names and state machine terminology don't match the spec's algorithm names, making it harder to trace spec compliance. Current → Spec: - PickerState enum → InteractionState (spec: "interaction states") - PickerState::Presenting → InteractionState::Requesting (spec: "requesting") - prepareCredentialRequest() → prepareCredentialRequests() (spec: "prepare credential requests") - abortPicker() → abortTheCredentialRequest() (spec: "abort the credential request") - dismissPickerAndSettle() → rejectTheCredentialRequestWith() (spec: "reject the credential request with") - handleDigitalCredentialsPickerResult() → initiateTheCredentialRequest() (spec: "initiate the credential request") - showDigitalCredentialsPicker() → showDigitalCredentialsChooser() (spec: "digital credential chooser") - dismissDigitalCredentialsPicker() → dismissDigitalCredentialsChooser() (spec: "digital credential chooser") This is a pure mechanical rename with no behavioral changes. Aligning names makes it trivial to cross-reference between spec and implementation and reduces review burden for future spec changes.
