ChangesAddon runtime flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change is intended to recover the add-on runtime during launches, but launch-hook failures can still bypass recovery and allow the game to start without the required hooks. Runtime restarts may also surface errors or leave update screens stuck, so this PR is not merge-ready until the recovery and retry behavior is corrected. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR introduces shared add-on client reconnection and launch-hook recovery, along with renderer readiness and add-on manifest handshake changes.
Confidence Score: 4/5The PR is not yet safe to merge because an unavailable runtime with no cached connection still leaves Play pending indefinitely instead of activating launch recovery. getAddonServer retries initial connection failures without a limit, while runLaunchAppAddons can restart the runtime only after the first hook attempt fails; therefore the existing launch-recovery failure remains outstanding.

When a launch starts with no cached connection and the add-on runtime is unavailable, getAddonServer retries forever instead of returning the error that triggers runLaunchAppAddons to restart the runtime, causing Play to wait indefinitely.

**Unbounded retry blocks launch recovery**
When a launch starts with no cached connection and the add-on runtime is unavailable, `getAddonServer` retries forever instead of returning the error that triggers `runLaunchAppAddons` to restart the runtime, causing Play to wait indefinitely.

In `@application/src/electron/main.ts`:
- Around line 414-419: Update the did-start-navigation handler in
mainWindow.webContents so rendererEventReadiness.reset() runs only for
main-frame, new-document navigations, excluding same-document History API and
fragment navigations. Add regression coverage verifying readiness is preserved
for both same-document navigation cases.
In `@application/src/frontend/App.svelte`:
- Line 234: After the await of getAddonServerPromise in the search flow, recheck
signal.aborted and activeQuery before constructing or sending any librarySearch
requests. Return or otherwise stop processing when cancellation is detected,
while preserving the existing request behavior for the still-active query.
In `@application/src/frontend/components/built/UpdateAppModal.svelte`:
- Line 116: Bound the await of getAddonServerPromise in the UpdateAppModal
onMount flow so an unavailable addon server settles by rejecting and reaches the
existing catch/error state instead of leaving loading active indefinitely; use
the existing addon-server utility and error symbols where needed, without
changing the successful source-loading path.
In `@application/src/frontend/lib/core/addons.ts`:
- Around line 67-86: Update runLaunchAppAddons to trigger addon-server restart
and retry when runLaunchAppAddonsOnce returns a result with success set to
false, rather than relying only on Effect.catchTag('AddonError'). Preserve the
existing recovery for AddonError failures and ensure the retried result is
returned so failed launch hooks are not treated as successful.
In `@application/src/frontend/lib/core/ipc.ts`:
- Around line 147-163: Extend the retry window in reconnectClientSdk around
connectClientSdk so it accommodates the full addon-server restart sequence,
while remaining bounded. Update the current Schedule.intersect configuration
rather than changing stale-connection cleanup or connection assignment, and
preserve successful reconnect behavior once the server becomes available.
- Around line 66-96: The shared connection producer in getAddonServer must not
inherit interruption from consumer fibers, because Effect.cached can retain an
interrupted result. Replace the cached connect execution with a detached
producer, such as a daemon fiber, and have callers join that producer for the
Connection while preserving connectionInFlight cleanup and addonServer
assignment.
In `@application/src/frontend/lib/tasks/runner.ts`:
- Line 45: Preserve the existing AddonError-only failure contract for
getAddonServer in runTask at application/src/frontend/lib/tasks/runner.ts:45-45
and loadDeferredTasks at application/src/frontend/lib/tasks/deferred.ts:15-24 by
mapping NetworkError to AddonError before continuing with the task effects, or
update every caller to handle NetworkError explicitly. Ensure both effects’
callers handle all possible failures.
In `@application/src/frontend/views/FocusedAddonView.svelte`:
- Line 122: Wrap the getAddonServerPromise call in updateConfig with the
existing error-handling path so connection lookup failures trigger the same
user-visible notification as configUpdate failures. Ensure all rejection paths
from updateConfig, including its existing callers, are handled without unhandled
promise rejections.

🌐 Web query:
Electron webContents did-start-navigation same document navigation isInPlace documentation
💡 Result:
In modern Electron versions, the isInPlace property within the did-start-navigation event is deprecated [1][2]. It has been replaced by the isSameDocument property, which is provided as part of the details object [1][2]. The isSameDocument property is a boolean that indicates whether the navigation occurs within the same document [1][2]. Navigations considered to be in the same document include: - Reference fragment (hash) changes [1][2]. - Use of the History API (pushState/replaceState) [1][2]. - Same-page history navigation [1][2]. Developers are encouraged to use the isSameDocument property instead of the deprecated isInPlace, which was used in older versions of Electron to identify "in-page" navigations [3][4][5]. If you are working with type definitions, ensure you are accessing this information through the details object rather than relying on the legacy event parameters [6].

An unavailable addon server leaves this modal in the loading state forever.
getAddonServerPromise resolves through getAddonServer, which retries connectClientSdk with Schedule.spaced('1 second') and no attempt limit. If the addon server is down, the promise at Line 116 never settles. loading is only cleared at Line 132, and the try/catch in onMount (Lines 56-65) never runs because nothing rejects. The user then sees "Loading sources..." with no error and no way to know the request failed.

🎯 Functional Correctness | 🔴 Critical | 🏗️ Heavy lift
The launch-hook recovery never runs for a failed launch hook.
runLaunchAppAddonsOnce does not fail with AddonError when a hook fails. It wraps each launchApp call in Effect.either (Line 57) and converts the first Left into the success value { success: false, error } (Lines 60-63). The effect therefore succeeds, and Effect.catchTag('AddonError', ...) at Line 72 is never reached for that case.
The result is that the exact failure this PR targets — a stale client socket rejecting launchApp — produces no restartAddonServer call and no retry. Only ensureAddonsSpawned and fetchAddonsWithConfigure failures reach the recovery branch.
Downstream impact: application/src/frontend/components/PlayPage.svelte Line 132 awaits runLaunchAppAddons and does not inspect success, so a failed pre-launch hook is treated as a successful one and the game still launches.
Trigger recovery from the returned success flag.

Effect 3.22 Effect.cached interruption behavior does it memoize interrupted first evaluation
💡 Result:
In Effect, Effect.cached does not memoize an interrupted first evaluation. If the initial computation is interrupted before it completes, the result is not cached, and subsequent evaluations will trigger the computation again [1]. When using Effect.cached, the first evaluation computes the result [2][3]. If multiple processes request the value simultaneously, they share the same underlying fiber [1]. Historically, interruption of a pending lookup could behave inconsistently (for example, one consumer interrupting the entire shared process) [4], but current behavior ensures that shared lookups are managed such that the effect is only considered "successfully cached" upon completion. If an interruption occurs during the execution, the cache entry is generally removed or invalidated, ensuring that subsequent calls attempt the computation again [1]. If you are encountering unexpected behavior regarding interruption, note that certain utility functions like Effect.cachedWithTTL have historically been associated with issues where they could inadvertently suppress interruption (e.g., due to internal usage of uninterruptible masks) [5]. However, the core Effect.cached functionality is designed to propagate failures and interruptions appropriately to ensure the cache does not store partial or cancelled states [1].

Effect 3.22.0 source Effect.cached memoized interruption implementation
💡 Result:
In Effect 3.22.0, memoization utilities like Effect.cached and Effect.cachedFunction are designed to compute an effect only once and cache the result for subsequent evaluations [1][2][3]. Regarding interruption, these utilities have historically faced challenges where internal masking could inadvertently suppress interruption signals (such as timeouts) during the initial computation phase [4]. Specifically, issues have been identified where utilities like Effect.cachedWithTTL utilized uninterruptible masks that prevented the propagation of interruption to the underlying effect [4]. For core caching mechanisms, recent improvements have focused on refining the lifecycle of shared lookups [5]. Improvements in the internal implementation, particularly in the Cache module, have been implemented to ensure that when multiple consumers share an in-progress lookup, the interruption of one consumer does not automatically interrupt the entire shared lookup [5]. Instead, the implementation now tracks "waiters" (consumers) using a reference-counting approach, ensuring the shared lookup is only interrupted when no consumers remain [5]. If you encounter issues where interruption is suppressed, a common workaround is to explicitly ensure the effect being cached is marked as interruptible (e.g., using Effect.interruptible) before passing it to the caching utility, or to be aware that some caching wrappers may internally mask the effect [4]. In the context of general Effect memoization, the library treats interruption as a signal that should propagate appropriately; if a specific utility does not honor this, it is typically addressed as a bug fix in ongoing releases [5][4].

Detach the shared connection producer from consumer fibers. In effect@3.22.0, Effect.cached stores an interrupted Exit and does not retry. Concurrent callers can therefore receive interruption instead of a Connection. Use a detached producer, such as a daemon fiber that callers join.

The reconnect retry budget is shorter than an addon-server restart.
reconnectClientSdk retries connectClientSdk at most 5 times at 250 ms intervals, so the total budget is about 1.25 s. restartAddonServer in application/src/electron/handlers/handler.addon.ts stops the server, stops each addon process, starts the server, retries an exponential health check, starts addons, and waits for manifests. That sequence normally exceeds 1.25 s. A queryConnectedAddons call that overlaps a restart will therefore fail its reconnect and surface an AddonError to the caller. Increase the reconnect window, or keep the reconnect bounded and let callers retry through getAddonServer.
🔧 Proposed wider reconnect window
addonServer = yield* connectClientSdk().pipe(

getAddonServer widens the error channel of both task effects. Both files replaced a module-level addonServer value with getAddonServer, which fails with NetworkError. Each effect previously failed only with AddonError, so any caller that matches solely on AddonError no longer handles every failure.

Description
Fixes intermittent Play failures where the renderer loses access to the add-on runtime and launching only works again after manually restarting the add-on server.
Connected add-on queries now recover stale client sockets through a shared reconnect. If the runtime remains unavailable during a launch hook, OpenGameInstaller restarts it once, reconnects, and retries the hook automatically.
Validated with the complete application test suite (102 passing), application type-checking, and Biome formatting checks.
