⚠️ Flaky E2E Tests (passed on retry)

These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.

  • addTenWorkflow (nextjs-turbopack)
  • cancelRun via CLI - cancelling a running workflow (nextjs-webpack)
  • deploymentId: 'latest' is a no-op in non-Vercel worlds (fastify)
  • no startIndex (reads all chunks) (tanstack-start)

🛠 Infra Events (absorbed by the harness)

Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.

⚠️ Flaky E2E Tests (passed on retry)
These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.
  • addTenWorkflow (nextjs-turbopack)
  • cancelRun via CLI - cancelling a running workflow (nextjs-webpack)
  • deploymentId: 'latest' is a no-op in non-Vercel worlds (fastify)
  • no startIndex (reads all chunks) (tanstack-start)
🛠 Infra Events (absorbed by the harness)
Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.

⚠️ Flaky E2E Tests (passed on retry)
These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.
  • addTenWorkflow (nextjs-turbopack)
  • cancelRun via CLI - cancelling a running workflow (nextjs-webpack)
  • deploymentId: 'latest' is a no-op in non-Vercel worlds (fastify)
  • no startIndex (reads all chunks) (tanstack-start)
🛠 Infra Events (absorbed by the harness)
Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.

⚠️ Flaky E2E Tests (passed on retry)
These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.
  • addTenWorkflow (nextjs-turbopack)
  • cancelRun via CLI - cancelling a running workflow (nextjs-webpack)
  • deploymentId: 'latest' is a no-op in non-Vercel worlds (fastify)
  • no startIndex (reads all chunks) (tanstack-start)
🛠 Infra Events (absorbed by the harness)
Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.

⚠️ Flaky E2E Tests (passed on retry)
These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.

⚠️ Flaky E2E Tests (passed on retry)
These tests failed at least once and passed on a retry. A recurring entry here is a real race worth investigating.
  • addTenWorkflow (nextjs-turbopack)
  • cancelRun via CLI - cancelling a running workflow (nextjs-webpack)
  • deploymentId: 'latest' is a no-op in non-Vercel worlds (fastify)
  • no startIndex (reads all chunks) (tanstack-start)
🛠 Infra Events (absorbed by the harness)
Platform anomalies the e2e harness detected and worked around (e.g. a run the queue never picked up, replaced by a fresh run). Clustered timestamps indicate a backend blip; a steady drip indicates a platform issue worth escalating.
