In `@packages/core/src/jsonRpc/transports/webSocket.ts`:
- Around line 169-176: Update the timeout handling around firstTimeout and
socketUnsafe.close to schedule a dedicated timer when a socket first enters the
grace period, closing the socket when SOCKET_TIMEOUT_GRACE_PERIOD expires
instead of waiting for another timeout event. Store the timer alongside the
existing timeout state, and clear or reset it when a response arrives or the
socket closes.
In `@packages/core/src/signer/jsonRpc/signer.ts`:
- Around line 290-294: Bound the recovery loop in recoverResult so provider
responses that remain pending cannot keep the outer retry alive indefinitely.
Add a total recovery deadline or propagate cancellation through request, both
retry calls, waitForVisibility, and the get_result request, ensuring
cancellation rejects recovery and allows cached promises to be cleared.
In `@packages/core/src/utils/index.ts`:
- Line 273: Update waitForVisibility to accept an optional AbortSignal and
settle on cancellation as well as visibilitychange, always removing both event
listeners in either path. In SignerJsonRpc.recoverResult, pass its recovery
signal to waitForVisibility so disconnect cancellation prevents stale get_result
calls.

In @.changeset/reconnect-khie-relays.md:
- Around line 2-3: Add an explicit note to the changeset documenting that Khie
connector and provider versions are incompatible across this change and must be
upgraded together, while retaining the existing relay reconnection release
description.
In `@packages/app/src/app/modules/khie/khie-signer-session.ts`:
- Around line 88-99: Update connectRelay around RelayConnectionController
creation to return false when this.resources.abortController.signal is already
aborted, before creating or assigning a controller. Preserve the existing
previous-controller handling and prevent pending relay starts from installing a
controller after releaseResources begins shutdown.
In `@packages/core/src/jsonRpc/requestor.ts`:
- Around line 196-208: Update the catch path in the request-waiter flow around
resolvePending so that when the aborted waiter is no longer found in pending,
the released concurrency permit is forwarded by waking the next queued waiter.
Preserve removal of the waiter when it is still present, then rethrow the abort
cause.
In `@packages/libp2p/src/relayConnection.ts`:
- Around line 78-80: Update the address selection logic around selectedAddress
so each retry cycle tries the selected relay first, then all other configured
addresses in their existing order. Exclude duplicates using address equality,
while preserving the current behavior when no relay is selected.

- Line 366: Update the outer retry configuration in the pending-result polling

statuses wait between get_result requests. Add a test covering several pending
responses and verifying the configured poll interval.

This PR adds recoverability for Khie. Even if not both sides of the Khie are alive, say on the Android browser and app wallet, as long as a window of time can be found after the operation (such as signing) has taken place, during which both parties are online, they can still exchange information asynchronously.
This should significantly improve usability for interactions involving the same device under strict backend management.
This is a breaking change at the Khie protocol layer. New and old connectors and providers are incompatible with each other.
