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.

Final answer

Perfect! I have successfully completed the backorder work for both products. Here's a summary:

Summary of Actions Completed

Stock Allocations from Received POs (7 P-DOC + 4 P-MON)

Allocated orders (6 orders, 6 customers notified):

O-5204: 2 P-DOC units allocated (platinum customer, earliest date)
O-5207: 1 P-DOC + 1 P-MON allocated together (platinum ship-complete order)
O-5202: 1 P-DOC + 1 P-MON allocated (gold customer)
O-5208: 2 P-MON units allocated (gold customer)
O-5209: 2 P-DOC units allocated (gold customer)
O-5210: 1 P-DOC unit allocated (gold customer)

Total used: All 7 P-DOC and 4 P-MON units fully allocated

Promise Dates Set for Still-Waiting Lines (8 orders, 8 customers notified)

Using in-transit purchase orders in priority order by arrival date:

O-5206: Both lines promised for 2026-08-06 (from PO-90 P-HUB and in-transit P-DOC)
O-5201, O-5211: Promised for 2026-08-03 (from PO-91)
O-5213, O-5215: Promised for 2026-08-14 (from PO-95)
O-5203, O-5212: Promised for 2026-08-05 (from PO-93)
O-5214: Promised for 2026-08-19 (from PO-97)

Customer Notifications

14 total customers notified (one per worked order)
6 customers notified of allocations ready to ship
8 customers notified of promise dates for waiting items

Note

O-5205 (risk hold): Correctly skipped per policy—no allocation, promise date, or customer contact made

All allocations respected priority rules (platinum/gold/standard tiers, then order dates) and ship-complete atomicity constraints.
