Did the design run?

every check held
  • Run completed: heldharness.run-completedThe environment was built, the architecture returned and grading finished, none of them throwing.
  • No API failures: heldharness.apiNo model call failed at the API.
  • Every call ended: heldharness.calls-endedEvery call ended with a result, or was stopped by the run's own limits.
  • No harness tool denied: heldharness.harness-toolsThe sandbox guard never denied a harness tool, nor a tool the session itself offered.
  • Tool servers connected: heldharness.mcp-connectedEvery tool server the harness gave a call was connected when the session started.
  • No foreign tool servers: heldharness.mcp-hermeticNo call loaded a tool server the harness did not give it.
  • Builtin tools: heldharness.builtin-toolsA check recorded with the run.
  • Structured replies arrived: heldharness.structured-outputEvery call that asked for structured output and ran to the end got it.
  • No silent fallbacks: heldharness.not-degradedNo phase fell back on a default (an empty plan, a default winner) instead of its output.
  • The task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

Final answer

Summary: Order O-3001 Return - End-to-End Processing

The three workers have completed the return process for customer Priya Raman (C-300), with the following results:

Money Side ✓

  • Total refunded: $686.00

    • $138.00 to card (RF-1): Line L3 cancellation (never shipped)
    • $548.00 to store credit (RF-2): Lines L1 + L2 returns (shipped past 30-day window)
  • Customer store credit updated to reflect the store credit refund

Order Record ✓

  • Order O-3001 status: changed from "partially_shipped" → "returned"
  • All three lines marked as refunded/cancelled with documentation
  • Refund methods applied correctly per policy

Warehouse Side ✓

  • All items received and restocked:

    • P-DOC: +1 unit
    • P-MON: +1 unit
    • P-HUB: +2 units
  • Goods are back in general inventory

⚠️ Issue Flagged

There is a customer balance discrepancy between workers:

  • The issue-refund worker reports the balance changed from $500.00 → $553.00 (a $53 increase)
  • The update-order-record worker reports the balance changed from $5.00 → $553.00 (a $548 increase, matching the store credit applied)

Only the second calculation is mathematically consistent with the $548 store-credit refund. The issue-refund worker appears to have logged an incorrect starting balance. Since the math works correctly in the update-order-record report, the customer's account should be accurate at $553.00, but this discrepancy should be verified against the actual account record.
