feat(expo-passkeys): support preferImmediatelyAvailableCredentials for passkey sign-in - #10776
Takeover of #10755 by @ketanchexy, who found and fixed this. Their commits are kept as-is.
Adds a preferImmediatelyAvailableCredentials option to signIn.authenticateWithPasskey() and signIn.passkey(). With @clerk/expo-passkeys on iOS 16+ and Android, sign-in only offers passkeys already on the device. When there are none, the request fails without showing the "use a passkey from another device" sheet. An app can then prompt for a passkey as soon as its sign-in screen opens, as the clerk-ios and clerk-android sign-in views already do. Browsers ignore the option, and it defaults to false.
Added in the takeover:
The iOS module compiles at the iOS 15.1 deployment target that Expo apps use. On iOS 15 the option is ignored and the usual sheet appears.
The native get keeps its shipped signature on iOS and Android, so passkey sign-in keeps working on Expo SDK 54 and in over-the-air updates to binaries built with an older @clerk/expo-passkeys. The option goes through a new native getWithOptions, which JavaScript calls only when the option is true and the binary has it.
The docs no longer promise a specific error code. With no passkey on the device, iOS reports passkey_registration_cancelled and Android reports passkey_retrieval_failed.
Tests for forwarding the option through @clerk/clerk-js and @clerk/expo.
On an iOS 27 simulator with no passkey saved for the relying party, get() without the option opens the system sheet for a passkey from another device. The simulator has Bluetooth off, so the sheet asks for Bluetooth instead of showing the QR code. With the option set to true, get() rejects in 19 ms with passkey_registration_cancelled and no sheet appears. The native get called with its shipped two arguments still opens the sheet. The Android module compiles. Android was not run on an emulator.
Option unset
preferImmediatelyAvailableCredentials: true

Walkthrough
The change adds preferImmediatelyAvailableCredentials to passkey sign-in parameters. Clerk forwards the option through its sign-in and Expo adapter paths to native Android and iOS credential requests. The native implementations apply the preference, and tests cover forwarding in sign-in and Expo adapter flows.
clerk/javascript#10755: Implements the same option across the same sign-in methods, Expo adapter, and native requests.

Merge Risk: Low · up to ea5b8
The new option defaults to false and existing passkey sign-in behavior is unchanged. Apps that enable it with older passkey adapters or native binaries may still see the cross-device sheet. This is a bounded follow-up, not a merge blocker.

🤖 AI review (reclassified as non-breaking) (85%): The change adds an optional parameter preferImmediatelyAvailableCredentials?: boolean to the get function's destructured argument object inside __experimental_passkeys. Since BuildClerkOptions is an input type (consumers pass it as a parameter, e.g. in ClerkProviderProps), widening the accepted input shape of a callback parameter — by adding an optional property to the object the library passes into the consumer's callback — is contravariant: consumers implementing get can safely ignore the new optional property, so no existing well-typed consumer code breaks.

🤖 AI review (reclassified as non-breaking) (95%): A new optional property preferImmediatelyAvailableCredentials? was added to AuthenticateWithPasskeyParams, which is used only in an input (parameter) position (authenticateWithPasskey(params?: AuthenticateWithPasskeyParams)). Existing callers that omit this property continue to compile and run correctly; no consumer is required to pass it.
With the option set, both sign-in methods call the new native getWithOptions with preferImmediatelyAvailableCredentials true on iOS and Android; before, the option was dropped and plain get ran.

On iOS 15.8 both sign-in methods throw passkey_not_supported before any native call, with or without the option, so no sheet appears; the same gate exists before the PR.

Do not send the new argument to an older native binary.
After an over-the-air update, true adds an argument to the old native get function. Expo validates native argument counts, so that call fails instead of signing in. Detect native support before using the new argument, or expose a separate versioned native method. (raw.githubusercontent.com)

Allow the documented iOS 15 fallback.
On iOS 15, isSupported() returns false, so both sign-in APIs throw passkey_not_supported before reaching AccountManager's standard-request fallback. The PR describes iOS 15 as ignoring the option and showing the usual sheet. Align the support check with that behavior, or document iOS 15 as unsupported.

Preserve the native error code in the Future API.
When iOS has no local credential, the adapter maps cancellation to passkey_registration_cancelled. This line replaces it with passkey_retrieval_failed, so signIn.passkey() does not return the iOS outcome described in the PR. An app that uses that code to select its fallback will miss it. Preserve the returned error or document the different Future API outcome. (raw.githubusercontent.com)

get keeps its shipped two-argument (iOS) and one-argument (Android) signature, and the option goes through a new getWithOptions that JS calls only when the option is on and the binary has it.
