Explanation
The description links issue
#1900, explains the implementation and expected behavior, and lists validation commands and focused tests. It does not reproduce the full template, including the pre-submission checklist and documentation-impact section, but the core required information is present.

-
Explanation
Issue [
#1900] requires an interrupted child to resume and create a new task. The PR adds explicit interrupted-child resumption, validates the parent await link under file locks, rejects stale children, preserves linkage across restart, and covers nested delegation with lifecycle, persistence, and provider tests.
Full details: Security Boundaries
-
Explanation
No changed path meets the security failure conditions.
Task.resumeTaskFromHistoryrequires an accepted resume response before preparation and activation (src/core/task/Task.ts:3257-3260), andTaskHistoryStore.resumeInterruptedTaskvalidates the disk record and parent linkage under file locks before activation (src/core/task-persistence/TaskHistoryStore.ts:1194-1227). The new recovery copies remain in the task storage directory and are written as JSON (src/core/task-persistence/apiMessages.ts:186-198). The diff adds no secret transmission, command execution, unvalidated execution sink, or approval/allowlist bypass.
Full details: Persistence Integrity
-
Explanation
PASS — no concrete changed persistence path meets the failure condition. Interrupted resume now creates a durable recovery copy, performs an exact expected-history compare plus an interrupted-record gate under the API-history lock, and activates only after preparation succeeds (
Task.ts:3403-3458,apiMessages.ts:290-330). A competing preparation therefore cannot replace the winner with different history. Failed restores retain the recovery copy, andsafeWriteJsonpreserves surviving backups on partial rollback failure. Relevant writes are awaited and regression tests cover concurrent resumes and partial failures. Prior failure addressed: The prior race is addressed by CAS preparation:prepareInterruptedResumeHistoryverifies interrupted status and expected disk history before commit; a competing resume with different prepared history is rejected, while failed restores retain the recovery copy. Added tests cover both race outcomes.

Explanation
The change in
webview-ui/playwright/themes.tsdisables CSS transitions in the Playwright theme helper. Issue [#1900] concerns interrupted-task resumption and child delegation. The reviewed evidence does not connect this test-helper change to that behavior.Resolution
Remove the
webview-ui/playwright/themes.tschange, or provide a concrete linked coding requirement that requires transition suppression in this test helper.
Full details: Regression Evidence
-
Explanation
Focused regression coverage remains incomplete.
ClineProvider.resumeInterruptedTaskadds separate parent-locked and top-level paths plus a launched-view update atsrc/core/webview/ClineProvider.ts:824-846, but direct provider tests only exercise a parent-linked resume withisViewLaunched: false(src/__tests__/ClineProvider.delegation.spec.ts:61-75). The launched-view test at lines 654-687 covers delegation, not resume or its payload.resumeInterruptedTaskrejects mismatchedexpectedParentTaskIdatsrc/core/task-persistence/taskLifecycle.ts:38-40, but no direct lifecycle test supplies a mismatched parent. The post-preparationthis.abandonedbranch insrc/core/task/Task.tsis not tested in isolation; the added test setsabortTask(true), which also setsabort, and other abandonment coverage exercises pending-action replay. Resume changes the persisted child status shown by the existingSubtaskRow/TaskStatusBadge, but the only HistoryView Playwright story and snapshots still cover empty history (webview-ui/playwright/gallery/stories.tsx:158-169andwebview-ui/src/components/history/__tests__/HistoryView.visual.tsx:8-23).Resolution
Add direct provider tests for top-level resume and launched-view resume. Assert delegation-lock usage and the exact
taskHistoryItemUpdatedpayload. Add a lifecycle test that passes a mismatched expected parent ID. Add a resume test that sets onlyabandoned = trueafter preparation and before activation. Add a HistoryView Playwright component story with per-theme snapshots for an interrupted child and its active resumed state, includingTaskStatusBadge.
Full details: Lifecycle Resource Cleanup
-
Explanation
Changed interrupted-resume paths still leave standalone tasks active after cancellation. In
Task.resumeTaskFromHistory, afterprovider.resumeInterruptedTaskcommits, the abort/abandon branch callsreinterruptAbandonedChildonly whenparentTaskIdexists, then restores history and returns; the changed code explicitly leaves a standalone recordactivewith no runner (Task.ts:3472-3492). The added test asserts this state (Task.resumeApiHistoryPersistence.spec.ts:378-410). The denied pending-action path has the same gap: for a standalone task, cancellation after activation skips re-interruption and still callsinitiateTaskLoop(Task.ts:3712-3726).initiateTaskLoopemitsTaskStartedbefore itswhile (!this.abort)guard (Task.ts:4123-4127), so cancellation can produce post-cancellation work. This is a concrete changed lifecycle path that leaks an active task without a runner and can duplicate work after cancellation.Resolution
After every interrupted-task activation, re-check
abortandabandonedfor standalone and child tasks. If cancellation or disposal wins after activation, persist an interrupted record with an ownership/status check, or otherwise roll back activation without overwriting a competing resume. In the denied pending-action path, return beforeinitiateTaskLoopwhen cancellation wins, and only passuserContentAlreadyPersistedwhen activation remains valid. Replace the standalone test expectations with assertions for noTaskStarted, no loop start, and an interrupted persisted record; add equivalent deferred-activation coverage for cancellation and disposal.

Could the parent ownership check and child activation share a cross-host lock or delegation generation so another host cannot re-delegate the parent between them?
There was a problem hiding this comment.
Implemented.
resumeInterruptedTaskholds the parent file advisory lock across the disk parent check and the child commit.withFileLockusesproper-lockfileon the task file, so the lock works across hosts.atomicUpdateParentDelegationtakes the same parent lock, re-reads the parent from disk, and requires the awaited child disk status to stayinterrupted.- The provider precheck is advisory only:
resumeInterruptedTask. - Tests cover both race directions: rejects resume after a competing host re-delegates the parent and rejects re-delegation after a competing host resumed the awaited child.

Could authoritative resume failures use a handled error type so missing or malformed task records also remove and dispose the failed history task?
There was a problem hiding this comment.
Implemented.
- Missing cache and missing or malformed disk records now throw
LifecycleTransitionError: cache check inresumeInterruptedTask, disk merge check in the merge callback, parent and child reads inreadValidatedTaskFile. cleanupFailedHistoryTaskremoves and disposes the failed task forLifecycleTransitionErrorandPendingActionSettlementError. It does not delete history.- Other error types skip this cleanup path: the type guard.
- Tests: absent cache does not create a record and the prior record stays recoverable when resume persistence fails.

Could we preserve explicit-resume ownership across restart, since startup currently treats this persisted active child as orphaned, interrupts it, releases its parent, and makes the next linked resume fail?

- Around line 3446-3459: After each successful resumeInterruptedTask() commit,
detect an aborted or abandoned child with a parentTaskId and call a provider
wrapper named reinterruptAbandonedChild() before returning; in the
history-resume path, restore the prepared API history before removing its
recovery copy, while the denied pending-action path only needs the
re-interruption. Implement the wrapper by delegating under the parent transition
lock to the existing markDelegatedChildInterrupted() operation.

- Line 3461: Update the post-commit abort/abandon handling around
resumeInterruptedTask so it runs for every aborted or abandoned task, not only
tasks with parentTaskId. Call reinterruptAbandonedChild only when parentTaskId
exists, then always restorePreparedResumeHistory and return; preserve the
standalone committed_elsewhere behavior so the recovery copy remains available.
Add a regression case in Task.resumeApiHistoryPersistence.spec.ts using a record
without parentTaskId, setting abort inside mocked resumeInterruptedTask, and
asserting the recovery copy remains and loop is not called.

## Task Lifecycle Changes

Source excerpt:
# Task lifecycle model-check suite
## Test layering
Add E2E coverage only when a lifecycle change crosses one of those runtime boundaries or introduces a new one. For example, #1453 persistence-readiness semantics require a controlled fresh-host test, and #369/#372 fan-out requires scheduler permit, live-parent routing, orphan cleanup, and task-scoping E2E. Do not add E2E cases solely to replay reducer orderings already exhausted here; they increase fixture and timing cost without strengthening the proof claim.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Do not treat an active disk status as committed_elsewhere for a resume that started as active.
This restore gate checks for diskStatus === "active" before it checks the starting status. That order is correct only when initialStatus === "interrupted": there, an active record means some activation commit landed.
A task can start as active, for example a standalone task that was resumed and later reopened from history. Its path never calls resumeInterruptedTask, so nothing commits. The failure sequence:
- Line 3422 writes
modifiedApiConversationHistorythroughoverwriteApiConversationHistory. When the last API message is a user turn, that write drops the turn. The dropped turn holds the realtool_resultblocks, and they now exist only innewUserContent. - A cancel sets
abortbefore Line 3439. Line 3440 then callsrestorePreparedResumeHistory. - The gate reads
activeand returnscommitted_elsewhere. No restore runs, so the disk keeps the shortened history. - The next resume reads the shortened history. It replaces the real tool results with synthetic "Task was interrupted" errors.
The recovery copy is kept, but nothing restores it automatically. A new .pre-resume-* file is left behind on each such abort. The docstring says the restore runs "while the persisted record still shows the status this resume started from". For active starts, the gate contradicts that.
Proposed fix
verifyCanRestore: async () => {
const diskStatus = await provider.taskHistoryStore.readValidatedDiskStatus(this.taskId)
- if (diskStatus === "active") {
+ const startStatus = this.initialStatus ?? "active"
+ // Only an interrupted start can be activated by a commit.
+ if (diskStatus === "active" && startStatus === "interrupted") {
return "committed_elsewhere"
}
- return diskStatus === (this.initialStatus ?? "active") ? "proceed" : "abort"
+ return diskStatus === startStatus ? "proceed" : "abort"
},Add a test in Task.resumeApiHistoryPersistence.spec.ts with these steps:
- Use a record with
status: "active"and an API history that ends with a user turn. - Abort after preparation, using the same spy pattern as the test at Line 450.
- Assert that the disk holds
authoritativeApiHistoryagain. - Assert that no recovery copy remains.

PR #1905 Review
Summary
- Verdict: Request changes.
- The PR adds an explicit, disk-authoritative resume path for interrupted tasks and serializes linked-child resume/redelegation through the parent-before-child lock order.
- Lifecycle ownership, restart reconciliation, API-history recovery, lineage preservation, and model coverage are substantially stronger, and all focused lifecycle validation passed.
- One failure path can still activate a task after durable pending-action settlement failed, leaving an active record with the denied action still replayable.
- The hosted
mutation-diffrequired check is also failing because 515 changed executable extension lines exceed the 500-line scope limit.

Plain-English summary
When a delegated child task is interrupted, accepting its resume prompt now performs a dedicated persisted transition instead of relying on a generic status write. The store revalidates the parent and child from disk while holding advisory locks, rejects stale ownership, marks explicitly resumed children for restart reconciliation, and keeps generic interrupted → active writes illegal. The change also prepares API history before activation, retains recovery copies around partial failures, preserves disk-owned lineage during stale metadata saves, and expands model and real-filesystem concurrency tests.
What I like
resumeInterruptedTask()andresumeInterruptedChild()make resume a named semantic operation while the generic transition table continues to rejectinterrupted → active.TaskHistoryStore.resumeInterruptedTask()validates authoritative disk records and uses parent-before-child lock order for linked children.TaskHistoryStore.atomicUpdateParentDelegation()bases redelegation on locked disk state rather than a stale host cache.restoreApiMessagesIfUnchanged()combines the record-state gate, exact-content comparison, and replacement write under the API-history advisory lock, and its outcome type makes failure modes observable.Task.restorePreparedResumeHistory()fails closed and retains the recovery copy whenever ownership or history cannot be proven.- The lifecycle model adds explicit resume, stale resume, denied replay, interrupted-child redelegation, and resumed nested-delegation coverage in
check-task-lifecycle.ts. - Real-filesystem concurrency coverage in
TaskHistoryStore.realConcurrency.spec.tsexercises stale hosts, lock waiting, restart ownership, failed renames, settlement races, and monotonic lineage detachment. - The persisted lifecycle remains separate from the pure in-memory
nextRunState()kernel, consistent with the target architecture. - No dependencies, lockfiles, changesets, changelogs, user-facing strings, telemetry contracts, or localization resources changed.
Questions
- Is the 515-line mutation scope intentionally approved as one review unit, or should the independent visual-theme fixture change and/or some lifecycle hardening be split so the required
mutation-diffgate can run? - Is durable pending-action settlement intended to be a precondition of interrupted-task activation? The lifecycle model and comments say yes, but
addToApiConversationHistory()currently reports only API-history persistence success. - Should retained resume recovery copies have a later cleanup or operator-discovery mechanism? Retaining them is the correct fail-closed behavior, but repeated ambiguous resumes can accumulate copies.
Blockers (must-fix)
1. The required mutation gate is failing on PR scope
The hosted mutation-diff check fails with: “Mutation gate failed: extension has 515 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.” The PR is therefore blocked even though its other hosted checks are green.
This is a process/CI blocker rather than a defect at one source line, so it should not receive a misleading inline code comment. Split an independent portion of the change or obtain the documented maintainer-reviewed narrow exclusion, then rerun the check.
Majors (should-fix)
2. A denial can activate the task even when pending-action settlement failed
Exact changed line: Task.resumePendingTaskAction(), with the activation at src/core/task/Task.ts:3712.
The new denial path uses the boolean from addToApiConversationHistory() as its activation gate. That boolean means only that the API-history write succeeded. If clearPendingActionAfterDurableResult() throws while clearing the task record, addToApiConversationHistory() logs and swallows the error, still returns true, and the caller activates the interrupted record. The disk can then contain all three of:
status: "active";- the durable denial result in API history; and
- the original
pendingAction, still eligible for replay after rehydration.
That contradicts the comment at src/core/task/Task.ts:3707 and the denied-replay landmark in check-task-lifecycle.ts, both of which assume the action is settled before activation. It also permits the resumed model loop to run while persisted lifecycle metadata still advertises unresolved work.
Make this path fail closed unless the matching pending action is authoritatively cleared. A bounded approach is to retry the idempotent settlement explicitly and verify the in-memory value reconciled from the store before activation:
if (!persisted) {
this.apiConversationHistory.pop()
throw new Error(/* existing error */)
}
+ await this.clearPendingActionAfterDurableResult(action.actionId)
+ if (this.pendingAction?.actionId === action.actionId) {
+ throw new PendingActionSettlementError(
+ `[Task#resumePendingTaskAction] Denial persisted but action ${action.actionId} is still pending`,
+ )
+ }
await provider.resumeInterruptedTask(this.taskId, this.parentTaskId)This reuses the compare-and-clear store operation and preserves a replacement action with a different identifier. An alternative structured persistence/settlement result from addToApiConversationHistory() would also work.
Add a real-filesystem regression test beside Task.resumeApiHistoryPersistence.spec.ts that allows the denial history write to commit, injects failure into the matching task-record settlement write, and proves activation and model execution do not start while the old action remains durable. Also cover successful retry from the resulting interrupted record.
Minors (nice-to-fix)
None.
Nits (style)
None.

- Intentionally omitted: VS Code extension-host E2E and manual interruption/restart testing. The PR adds strong reducer, store, provider, and real-filesystem integration coverage, but only a real host can validate process death at every resume phase and watcher behavior across multiple extension hosts.
Risk assessment (what could break, where, and why)
- Persisted lifecycle integrity — medium-high: resume/redelegation ownership is much stronger, but the pending-action settlement gap can produce an active record with replayable durable work.
- Concurrency — medium: parent-before-child ordering and locked disk revalidation cover the target race well. The architecture still documents broader live-task lineage and attempt-generation gaps outside this PR.
- Recovery and data integrity — low-to-medium: API history uses compare-and-set restoration and durable recovery copies. Ambiguous outcomes preserve data rather than overwrite it, at the cost of possible retained copies.
- Restart behavior — medium: explicit resumed-child ownership is represented and reconciled. Focused tests cover restart semantics, but no real extension-host restart test was run locally.
- Scheduler behavior — low: parent delegation persists before child scheduling, and the provider handoff/scheduler model passed.
- Security and privacy — low: persisted content remains local; no new network, authentication, authorization, secret, telemetry, or untrusted-deserialization boundary was introduced.
- Performance — low-to-medium: resume and redelegation add narrow advisory-lock reads/writes. They are control-plane operations, not hot token-stream paths, but multi-host contention now intentionally waits on parent/child locks.
- Compatibility — low: the optional
HistoryItem.explicitResumefield is backward-compatible with existing records. Generic transition behavior is intentionally stricter only for invalid stale activation. - Build/CI — high until resolved: the required mutation scope gate is red, independently of functional correctness.
Suggested follow-ups (if any)
- Make authoritative pending-action settlement a hard precondition of interrupted denial activation and add the injected settlement-failure regression test.
- Split the PR or obtain the documented maintainer-reviewed mutation-scope exclusion, then rerun the required check.
- Consider a bounded cleanup/discovery policy for retained resume recovery copies after the correctness work lands.
- Keep the current explicit-resume reducer, parent-before-child locking, disk-authoritative lineage, and model landmarks; these are the strongest parts of the change.

There was a problem hiding this comment.
Can activation also require authoritative pending-action settlement? This boolean remains true when the API-history write succeeds but clearing the matching task-record action throws, because that error is logged and swallowed. The following activation can therefore persist active while the denied action remains replayable. Please fail closed until the matching action is confirmed cleared, and add an injected settlement-write failure test.
