These local results were supplied by the author. The PR preparation did not rerun the tests.
Backend suite:src/__tests__/ClineProvider.subtask-links.spec.ts is enabled. CI decides whether it passes.
Locally, the vi.mock calls never take effect. At runtime, readTaskMessages is the real function, not a mock.
The installed Vitest is 4.1.11, but the pnpm catalog pins 4.1.12.
The existing committed suite ClineProvider.history-resume-delegation.spec.ts fails locally the same way: 36 of 38 tests.
The version mismatch is a suspected cause, not a proven one.
Webview spec:ChatRow.subtask-links.spec.tsx: 24 of 24 passed.
Backend types:pnpm --dir src run check-types: passed.
Backend lint: src eslint with --prune-suppressions --max-warnings=0 on ClineProvider.ts and the new spec: passed.
Suppression counts did not change.
Webview checks: webview-ui tsc --noEmit and eslint on both ChatRow files: passed.
Broader backend tests:npx vitest run core/webview from src/: 185 failed, 216 passed, 11 skipped, across 24 failing files.
These failures were not checked against a clean checkout.
They are not established as pre-existing or unrelated to this change. Check them in CI.
Commit hygiene:git diff --cached --check passed. The committed file list matches the five approved paths.
Reviewers should rerun the focused suites and broader backend tests in CI with the correct dependency environment.

Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.
Improved links between delegated tasks and their results, including when tasks finish out of order or have identical summaries.
Saved child-task identifiers for matching delegation messages and preserved existing identifiers when message updates omit them.
Improved handling of older task histories without explicit child-task identifiers while maintaining links when identifiers are available.
Avoided duplicate result entries for the same child task and prevented results from being associated with a different child.
The change adds optional child task identity to delegated messages. The provider stamps matching delegation asks and matches resumed results by child identity. Chat rows use stamps and legacy positional mapping to resolve subtask navigation links.
The message schema accepts an optional childTaskId. After the history update, the provider scans saved messages for the newest parseable newTask ask. It stamps and saves the ask only when its content matches the delegated message and it has no child ID. Tests cover matching, non-matching, and persistence outcomes, including retention of a disk-stored child ID during snapshot merging.
Resumed result identity src/core/webview/ClineProvider.ts, src/__tests__/ClineProvider.subtask-links.spec.ts
Synthetic results include the child ID. The provider matches an existing result by text and child ID, fills in an absent ID, or appends a result when the existing one belongs to another child. Tests cover these cases.
The added regression test protects child-task identity during message merging. The previously reported incomplete mock is corrected; no concrete merge-blocking issue remains, subject to normal checks.

Full details: Security Boundaries
Explanation
No changed path introduces a concrete security-boundary failure. ClineProvider.ts parses the persisted ask text only to identify newTask and exact-match its content; it never executes parsed data, and it stamps only the internally created child.taskId (lines 4268-4289). Resumed results similarly use the already-authorized childTaskId for message identity (lines 4386-4405). ChatRow.tsx uses these IDs only for the existing showTaskWithId navigation message (lines 917-925 and 1081-1089); the handler resolves tasks through the existing history lookup before opening them (ClineProvider.ts lines 2479-2486). No secret or PII flow, approval bypass, or new executable-input path is present.
Full details: Persistence Integrity
Explanation
No changed persistence integrity defect found. delegateParentAndOpenChild awaits readTaskMessages and saveTaskMessages before scheduling the child (src/core/webview/ClineProvider.ts:4262-4301), and its catch logs the link-write failure as explicit partial-failure behavior. saveTaskMessages performs the merge under the file lock and safeWriteJson uses temporary-file replacement with rollback (src/core/task-persistence/taskMessages.ts:76-99, src/utils/safeWriteJson.ts:78-191). The resumed-result save is also awaited (ClineProvider.ts:4386-4410). The optional childTaskId adds no persisted default that could be dropped.
Full details: Lifecycle Resource Cleanup
Explanation
No changed lifecycle path introduces a resource leak or duplicate work. The provider changes only read and save persisted messages before the existing child scheduling call, and add or update childTaskId on persisted results. The diff adds no listener, watcher, timer, or provider registration. The existing TaskScheduler releases permits in finally and skips aborted or abandoned tasks. The resumed-parent path retains cancellation and stale-instance guards.

Explanation
The description covers the implementation, tests, scope, documentation impact, and known test limitations. However, the mandatory approved GitHub Issue link is missing, the checklist remains incomplete, and the required Get in Touch section is absent.
Resolution
Link an approved GitHub Issue, complete the remaining required checklist items after review, and add the required Get in Touch section with the contributor's Discord username.
Full details: Regression Evidence
Explanation
The PR changes durable visible ChatRow behavior. getLinkedChildTaskId now controls whether Go to subtask buttons appear and which child ID they target for newTask and subtask_result rows (ChatRow.tsx:119-147, 893-925, 1067-1090). The added ChatRow.subtask-links.spec.tsx is a Vitest/RTL interaction test, not a Playwright component visual test. The changed-file inventory contains no ChatRow .visual.tsx test or snapshots. The Playwright configuration requires **/*.visual.tsx tests and stores snapshots under __screenshots__ (playwright-ct.config.ts:29-32).
Resolution
Add a ChatRow Playwright component visual test that renders stamped, legacy-fallback, and unresolved subtask-link states. Add and commit the required component snapshots under the configured __screenshots__ path. Keep the focused RTL interaction tests for child-ID routing.

- Around line 90-91: Restore the persisted subtask links suite by removing
describe.skip, and make its mocks compatible with the pinned Vitest version or
inject the persistence dependencies so the tests run reliably. Keep
behavior-focused regression assertions covering

Review comments at @src/core/webview/ClineProvider.ts:
- Around line 4262-4294: In delegateParentAndOpenChild, the reverse scan can
associate the child with an unrelated newTask ask; match each candidate against
the current delegation using its pending action or normalized payload before
setting childTaskId, and skip stamping when no matching ask exists.
Review comments at @webview-ui/src/components/chat/ChatRow.tsx:
- Around line 1073-1079: Remove the trailing completedByChildId fallback from
the getLinkedChildTaskId result in the completedChildTaskId assignment in
ChatRow. Keep passing completedByChildId into the resolver, which handles the
fallback when no subtask_result follows, so earlier results that resolve to
undefined are not linked to the most recently completed child.

The merge preserves childTaskId for matched snapshots.
mergeClineMessageSnapshots returns { ...disk, ...next }, so the incoming childTaskId overwrites the persisted message field. Matching by messageId or timestamp does not discard the stamp.
The only exception is the existing stale-partial guard, which returns disk when disk.partial !== true and next.partial === true. The supplied caller flow does not establish that state.
@edelauna Thanks for the review. I added the merge-level test you suggested in 319f712 (details in the inline thread). It covers the real mergeClineMessageSnapshots path, which the ClineProvider spec mocks out.
