WalkthroughCancellation now records its source in task transition payloads and final messages. Agent-task execution tracks cancellation provenance, separates timeout failures, and propagates parent or workflow sources through assistant, runtime, dependency-injection, and workflow controllers. ChangesCancellation provenance and timeout handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Queued tool-task cancellations still omit who canceled them while running cancellations record that information, leaving incomplete and inconsistent cancellation provenance. The PR should not merge until this is fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

532-545: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winRecord provenance for queued tool-task cancellations.
When the task is queued,
finishTransactionpersists line 535 as thetask_canceledevent payload. That payload has nocanceled_byvalue. The running path recordscanceled_by: "parent".Add the same cancellation source to the queued terminal payload.

Inline comments:
In `@internal/agenttask/service.go`:
- Around line 513-516: Update execute and finalizeRun so cancellation provenance
is read from the durable task_canceling event’s canceled_by field during
finalization, rather than relying solely on cancelSources[taskID] or the context
error; retain the in-memory entry only as a cache and remove it after
finalization. Ensure cross-process and normal running cancellations produce the
requester-derived final message, and add an execution-path regression test
covering a running task cancellation and its final requester message.
In `@internal/workflow/workflow_test.go`:
- Line 86: Update the fakeController Cancel implementations in
internal/workflow/workflow_test.go (lines 86-86) and
internal/workflow/service_internal_test.go (lines 34-35) to retain the source
argument instead of discarding it, and update the relevant cancellation
assertions to require database.CancelSourceWorkflow in both files.
Apply the same fix in `@internal/assistant/workflow_controller_internal_test.go`
around lines 54 - 55: Same source-recording and assertion gap.
