Effect PersistedCache get uninterruptible lookup interruption semantics
💡 Result:
In the Effect library, PersistedCache relies on an internal Cache mechanism to manage its lookups [1][2]. The interruption semantics of PersistedCache lookups are primarily dictated by the underlying behavior of this Cache [1][2]. As of recent updates, there is a known issue (tracked as issue #7608) where the underlying Cache may inadvertently retain and cache the result of a synchronously interrupted lookup [3]. When a lookup is interrupted synchronously before completion, the Cache may treat that interruption as a final result and store it, causing subsequent lookups for the same key to return the interrupted state rather than re-executing the lookup [3]. Because PersistedCache specifically uses the Cache to store the Exit value of the provided lookup function (which includes potential interruptions) [1][2], any such interrupted Exit result can be propagated to the persistent backing store as well. If you require uninterruptible behavior for your lookup, you should manually wrap the lookup effect in Effect.uninterruptible to ensure that the process completes its execution regardless of fiber interruption signals [3]. Relying on the default caching behavior currently poses a risk of "poisoning" the cache with interrupted results, which will persist until the key is explicitly invalidated [1][3].

Effect 4.0.0-rc.112 Effect.uninterruptible documentation interruption semantics
💡 Result:
In the Effect ecosystem, Effect.uninterruptible is a combinator used to mark an effect (and everything within its scope) as uninterruptible [1][2][3]. When applied, the operation will ignore interruption signals, including those triggered by mechanisms like Effect.timeout or explicit fiber cancellation, until the operation completes [1][4]. Key interruption semantics include: Cooperative Interruption: Interruption in Effect is cooperative, not preemptive [3]. Fibers check for interruption at specific yield points [3]. When an effect is marked as uninterruptible, these checks are suppressed or ignored, forcing the fiber to run to completion regardless of external termination requests [1]. Suppression of Timeouts: Since Effect.timeout relies on interruption to stop tasks that exceed a duration threshold, an uninterruptible effect will override this behavior [1]. If a task is marked uninterruptible, the timeout mechanism will wait for the effect to finish completely before raising a TimeoutException [1]. Nested Interruptibility: You can create "interruptible gaps" within an uninterruptible region by using the Effect.interruptible combinator [3][5]. Conversely, if you need to perform an operation uninterruptibly while keeping the ability to restore interruptibility, developers often use Effect.uninterruptibleMask, which provides a restore function [2][6]. Best Practices: - Use Effect.uninterruptible sparingly, as it can lead to hung fibers or system inconsistencies if not managed correctly [2]. - When working with sensitive operations (like those inside a timeout or race), ensure you are aware of whether the operation inherits uninterruptibility [7][4]. - Use Effect.disconnect if you need an uninterruptible effect to complete in the background while allowing the main control flow to proceed after a timeout [1]. While these concepts are stable across recent versions, always ensure your implementation is tested for proper cleanup, as marking an effect uninterruptible prevents standard onInterrupt hooks from firing until the region concludes [3].

site:github.com/Effect-TS/effect PersistedCache.ts 4.0.0-rc.112 uninterruptible interrupted lookup
💡 Result:
In the Effect library, particularly around version 4.0.0-rc.112, PersistedCache utilizes the Cache module to handle lookups [1][2][3]. A known issue exists where the Cache module (which powers the lookup mechanism in PersistedCache) could retain synchronously interrupted lookups [3]. When a lookup is interrupted, the system might erroneously cache the "interrupted" state instead of retrying the operation, causing subsequent requests for the same key to also be interrupted without re-running the lookup [3]. This behavior can also lead to the eviction of valid, unrelated entries from the cache [3]. The resolution for this behavior involves ensuring that interrupted lookups are not incorrectly cached, an issue addressed by PR #7614, titled "fix(Cache): avoid caching synchronous interruptions" [3]. Users experiencing this issue are encouraged to ensure they are on a version of Effect that includes this fix or to ensure that lookups do not interrupt synchronously before completion [3].

Effect PR 7614 fix Cache avoid caching synchronous interruptions release version 4.0.0-rc.112
💡 Result:
Pull Request #7614, titled fix(Cache): avoid caching synchronous interruptions, addresses a bug in the Effect library where synchronously interrupted Cache.get lookups were incorrectly cached [1][2]. The issue occurred because a synchronously interrupted lookup could complete before its entry was published to the cache [1]. Consequently, the cleanup process would fail to find an entry to remove, causing future reads of that key to replay the cached interruption instead of re-running the lookup [1]. This could also lead to valid, unrelated values being evicted from a full cache [2]. The fix involves checking the lookup fiber after observer registration and skipping publication if the fiber has already completed with an interruption [1]. This ensures that the cache does not store interrupted results, allowing subsequent attempts to correctly retry the lookup [1]. While this fix is associated with the issue "Cache.get retains synchronously interrupted lookups" (#7608) [2], it was merged into the main branch on September 2, 2026 [1]. Effect release 4.0.0-rc.112 was published on August 25, 2026 [3]. As the fix was merged on September 2, it is not included in 4.0.0-rc.112 [1][3].

Upgrade the Effect dependency before narrowing Effect.uninterruptible
Effect.uninterruptible protects PersistedCache.get and its provider lookup from the interrupted-lookup cache bug in effect@4.0.0-rc.112. Removing it now can replay interrupted lookups. However, the same scope prevents outer timeouts from stopping a hung CLI read. Upgrade to a release containing the cache fix, then add an interruptible timeout around provider reads while preserving safe cache publication.

requireProject now runs on every cached read, and twice on a miss.
persistedRead resolves the project to build the cache key. summaryUncached and stackUncached also call requireProject on the same input. Two consequences follow:
- A cache hit pays one full
requireProject. That call goes throughlistWorkspaceProjects, which reads the projection shell snapshot and can runrefineUnknownProjectKindswith provider handle resolution atREPOSITORY_CONCURRENCY. Before this change the hit path usedrefCacheKey, which needs no project resolution. - A cache miss pays
requireProjecttwice.
Consider resolving the project once in persistedRead and passing the resolved SupportedProject to the read builder, so the uncached read does not repeat the resolution.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The reference-scoped invalidation clears the persistent cache, but the workspace-wide branch does not.
Line 2673 calls readCache.invalidate when input.reference is defined. The else branch that follows handles invalidate({}), which is the broader workspace-wide invalidation. That branch bumps listingsEpoch and clears viewersByHost, but it does not call readCache.invalidate.
The result is inverted scope: a caller that invalidates one reference drops every persisted summary and stack, while a caller that invalidates everything leaves all of them in place for up to the 60-second expiry. A client that requests a full refresh therefore continues to receive cached summary and stack data.

Merges `pingdotgg/t3code` `2a3035353..0f602b3` (16 commits) into the fork. - **Landed:** 283 files (`HEAD^1..HEAD`) against 277 in the upstream range — `merge-stats.mjs` reports an exact 277/277 file match, so nothing in the range was dropped and nothing extra came in. The six over are three typecheck fixes and three fork docs, both listed below. Fork delta 733 files (`HEAD^2..HEAD`). - **Conflicts:** 6 files, all on one upstream feature (pingdotgg#10839, linking several pull requests to a thread). Resolutions in `docs/fork/upstream-merge-log.md`. - **Sweep:** 13 owned-concern hits, all `infra/relay/**` FCM/Android-push files under the decided-out `cloud-relay-connect` concern. Inherited in tree, adopted by nothing. - **Unsupported methods:** 0 ADD, 0 DROP — no `packages/contracts/src/rpc.ts` edit needed. ## What upstream shipped ### Usable as-is against Moatless Pure client work, no backend involvement — these are live the moment this merges. - **pingdotgg#11020** message copy buttons show on touch devices. - **pingdotgg#11018** middle-click pastes in the terminal on Linux. - **pingdotgg#10869** expanded images zoom and pan. - **pingdotgg#11002** the composer uses the available space for model names. - **pingdotgg#10981** duplicate tool-call commands can be expanded independently. - **pingdotgg#10947** provider settings grow a bulk model toggle. - **pingdotgg#10609** the PR list's diff counts return to the top right. - **pingdotgg#11022** remote projects open in Zed (`packages/contracts/src/editor.ts` plus the desktop shell — the fork ships both). - **pingdotgg#10998 / pingdotgg#10983 / pingdotgg#10964** three Android glass/overlap fixes in `apps/mobile`. ### Unsupported in Moatless — needs backend implementation - **pingdotgg#10839 — several pull requests per thread.** This is the substantive decision in the merge. Upstream now carries `thread.pullRequests: ThreadPullRequestLink[]`, `packages/shared/src/threadPullRequests.ts`, and a `ThreadPullRequestBadgeControl` pill with its own `pull-requests` stack tab. That is exactly the equivalent the fork's `task-bound-pull-request` convergence entry said to re-home its `+N` menu onto — but it cannot be re-homed yet: Moatless serves no `pullRequests` array on a thread and does not advertise the new `threadPullRequests` capability, so upstream's badge would resolve to nothing and paint an empty pill over a working one. Taking `theirs` would have silently deleted live fork behaviour. **Resolution:** upstream's implementation landed whole, and the two presentations are switched on `useSupportsMultiplePullRequests` — upstream's badge and stack where the server advertises the capability, the fork's binding-derived pill and `+N` menu where it does not. Additive, no prop threading, and it re-homes itself the day the backend advertises. `docs/fork/inventory.json` and `docs/fork/gaps.md` are updated with the switch and with the exact deletion list for when that happens. **To close it:** serve `thread.pullRequests` on `OrchestrationThread`/`OrchestrationThreadShell` from `task_bindings`, and report `capabilities.threadPullRequests: true`. - **pingdotgg#10870 — find threads by linked pull request.** Search terms come off the same `thread.pullRequests` array, so sidebar and command-palette search by PR number/URL match nothing here until the array is served. Closes with pingdotgg#10839. - **pingdotgg#10875 — navigate, merge and rebase GitHub stacks.** Adds two RPC methods, `pullRequests.stack` and `pullRequests.linkedThreads`, which the Moatless backend does not dispatch. Both are already covered by the shared `PullRequestRpcError` union, so the client decodes the refusal correctly and the stack UI stays inert — no contract change needed. Implementing the two methods is what turns it on. - **pingdotgg#10416 — Android agent notifications and ongoing activity.** Rides FCM through `infra/relay`, which is part of the decided-out `cloud-relay-connect` concern (being removed with Clerk). Inherited in tree, not adopted. ### Backend behaviour worth reproducing in Moatless - **pingdotgg#11007 — recent PR reads survive a server restart.** Upstream added `apps/server/src/pullRequest/PullRequestReadCache.ts`, persisting which pull requests a user has already read so a restart does not re-mark the whole list unread. Moatless owns this surface itself, so nothing in this repository holds it open — recorded so whoever touches the backend's PR read state knows the answer exists upstream. ## Verification `verify.mjs`, seven of eight green: `duplicate-adds`, `tripwires`, `resolution-check`, `unsupported-methods`, `fmt:check`, `lint`, `typecheck`. `test` is red on `@t3tools/desktop` alone — `scripts/browser-secret-native.test.mjs > bundled libsecret helper` fails to compile because `libsecret-1` is not installed in this sandbox. **Pre-existing environment gap, not merge-introduced:** it is already an entry in `docs/fork/gaps.md`, and `git diff --name-only HEAD^1 HEAD | grep browser-secret` is empty. 100 of 102 desktop files pass. Four packages did not finish under `vp run -r test` (`@t3tools/mobile`, `t3`, `@t3tools/web`, `t3code-relay`) and all four pass when run alone, which is parallel load rather than the merge. Three typecheck failures were fixed in the merge commit, all fork-only web code that upstream's widened shared types reached: `sandboxControl.placement.test.tsx` needed the two new `RightPanelTabs` props, and `useSandboxAvailability.ts` / `useSandboxDetail.ts` needed `isSuccess` threaded through now that `EnvironmentQueryView` carries it. Nothing is unresolved. --- Moatless task: https://moatless.soaplabstest.com/tasks/db1b3cbe-4401-441b-bbec-6b0c725c93ce

Backend hot reloads and server updates discarded fresh PR summaries and stack reads, making the restarted server fetch them again from GitHub.
Use Effect PersistedCache with a filesystem KeyValueStore under the environment caches/pull-requests directory in dev and production. The memory and disk caches share the original one-minute expiry. Failed reads are not persisted, and cache storage failures fall back to provider reads without repeating an already completed lookup. A missing cache directory falls back to memory.
Explicit refreshes, turns, and mutations clear persisted reads. Invalidation waits for active readers so an earlier request cannot restore invalidated data. Currently invalidation clears the dedicated PR cache as a whole. There is no database migration.
Validation: 116 focused PR service/cache tests passed, including filesystem reuse across service recreation, original expiry, in-flight invalidation, long keys, and failed reads. Scoped server typecheck and targeted lint passed. Fresh independent review found no blockers.
