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 plan was a plan: heldplan-execute.planThe planner’s reply was read through its schema and held at least one step.
  • Each call was shown the right tools: heldplan-execute.toolsThe planner was shown no tools and the executor the task’s full toolset.

Plan: 0.0s to 52.6s, finished, 0 tool calls, $0.037

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Perfect! I have completed the backorder processing task. Here's a summary of what was done:

Summary of Actions Completed

P-DOC (Laptop Dock) - PO-88: 7 units received

Allocations made:

  1. O-5204 L1 (Dev Patel, platinum): 2 units ✓
  2. O-5207 L1 (Lena Brandt, platinum, ship-complete): 1 unit ✓
  3. O-5202 L2 (Ben Okafor, gold): 1 unit ✓
  4. O-5209 L1 (Gus Lindgren, gold): 2 units ✓
  5. O-5210 L1 (Hana Sato, gold): 1 unit ✓
    Total allocated: 7/7 units

Promise dates set for waiting lines:

  • O-5206 L1 (Ivo Petrov, platinum, ship-complete): 2026-08-03 (from PO-91)
  • O-5201 L1 (Ana Costa, standard): 2026-08-03 (from PO-91)

P-MON (Monitor) - PO-89: 4 units received

Allocations made:

  1. O-5207 L2 (Lena Brandt, platinum, ship-complete): 1 unit ✓
  2. O-5202 L1 (Ben Okafor, gold): 1 unit ✓
  3. O-5208 L1 (Fay Morgan, gold): 2 units ✓
    Total allocated: 4/4 units

Promise dates set for waiting lines:

  • O-5203 L1 (Cara Jensen, standard): 2026-08-05 (from PO-93)
  • O-5212 L1 (Mona Aziz, standard): 2026-08-05 (from PO-93)
  • O-5214 L1 (Olga Petrova, standard): 2026-08-19 (from PO-97)

Special Handling

  • O-5207: Ship-complete order - both P-DOC L1 and P-MON L2 allocated together
  • O-5206: Ship-complete order - P-DOC L1 promised for 2026-08-03, but order will wait for P-HUB L2
  • O-5205: Risk hold order - left untouched per policy (no allocation, no promise date, no customer contact)

Customer Notifications

Sent 11 customer notifications explaining allocation status and promise dates for all affected customers (excluding the risk-held order).

All allocations followed proper priority rules (loyalty tier first, then earliest order date), and all waiting lines received promise dates based on in-transit purchase orders.
