- Around line 1-8: Replace the mocked send implementation on the mockIpc object
used to construct SharedRuntimeManager: change send from vi.fn() to a plain
no-op function (e.g., () => {}) so tests do not rely on vitest mocks; update the
mockIpc declaration where it appears and keep using it only to instantiate
SharedRuntimeManager (reference: mockIpc.send and SharedRuntimeManager).

📄 CodeRabbit inference engine (.cursor/rules/otel-metrics.mdc)
**/*.ts: When creating or editing OTEL metrics (counters, histograms, gauges), ensure metric attributes have low cardinality by using only enums, booleans, bounded error codes, or bounded shard IDs
Do not use high-cardinality attributes in OTEL metrics such as UUIDs/IDs (envId, userId, runId, projectId, organizationId), unbounded integers (itemCount, batchSize, retryCount), timestamps (createdAt, startTime), or free-form strings (errorMessage, taskName, queueName)
When exporting OTEL metrics via OTLP to Prometheus, be aware that the exporter automatically adds unit suffixes to metric names (e.g., 'my_duration_ms' becomes 'my_duration_ms_milliseconds', 'my_counter' becomes 'my_counter_total'). Account for these transformations when writing Grafana dashboards or Prometheus queries

Learning: In `packages/core/src/v3/errors.ts`, within the `taskRunErrorEnhancer` function, `error.message` is always defined, so it's safe to directly call `error.message.includes("SIGTERM")` without additional checks.

Learning: In apps/webapp/app/services/runsRepository.server.ts, the in-memory status filtering after fetching runs from Prisma is intentionally used as a workaround for ClickHouse data delays. This approach is acceptable because the result set is limited to a maximum of 100 runs due to pagination, making the performance impact negligible.

Closes #2942
This PR fixes an issue where run.taskIdentifier was reported as "unknown" when using batch.triggerAndWait / batch.triggerByTaskAndWait.
The root cause was that taskIdentifier was not propagated from the platform to the worker via the
CompletedWaitpoint
, causing the runtime to fall back to "unknown".
Changes
Schema
Added taskIdentifier to the
CompletedWaitpoint
schema (
packages/core/src/v3/schemas/runEngine.ts
)
Platform
Updated
ExecutionSnapshotSystem
to:
Select taskIdentifier from the database
Map it onto the
CompletedWaitpoint
sent to the worker (
internal-packages/run-engine/src/engine/systems/executionSnapshotSystem.ts
)
Worker
Updated
SharedRuntimeManager
to use waitpoint.completedByTaskRun.taskIdentifier when constructing the execution result (
packages/core/src/v3/runtime/sharedRuntimeManager.ts
)
Added a backward-compatible fallback to "unknown" for legacy runs
Verification
Unit Tests
Added
packages/core/src/v3/runtime/sharedRuntimeManager.test.ts
covering:
Correct propagation of taskIdentifier when present
Graceful fallback to "unknown" when missing
All tests are passing.
