  • 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.

  • 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.

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

I've worked the dock and monitor backorders. 11 orders now have stock set aside, the 3 that still have waiting lines have promise dates, one order on risk hold was left alone, and all 14 customers I worked have had one notice each.

Things that differ from the plan:

  • Date: The system says today is 2026-07-25, not 2026-10-06 as the plan states. PO-88 and PO-89 were both received on 07-25, so I used that date.
  • More stock arrived while I was working: PO-91 (4 docks) and PO-93 (3 monitors) were received during the run, so they were no longer in transit and couldn't be used for promise dates. The handbook says received stock goes to waiting lines in priority order, so I allocated it too. In total that was 11 docks and 7 monitors. I checked that the lines I'd already allocated would have come out the same if I had started with all of the stock at once. I re-checked the purchase orders before setting dates and before sending notices.

Policy updates:

  • PU-12 applies (in force from 2026-07-01, no end date). Orders placed 14 or more days before today, so on or before 07-11, go to the front of the queue, oldest first, whatever the customer's tier.
  • PU-9 does not apply. It only covered June (gold customers ranking with platinum).

Priority order used: the older orders first (O-5201, O-5202, O-5203, O-5204), then platinum (O-5206, O-5207), then gold (O-5208, O-5209, O-5210), then standard (O-5211, O-5212, O-5213, O-5214, O-5215).

Allocated (each line in full):

  • Docks (11): O-5201 L1 ×2, O-5202 L2 ×1, O-5204 L1 ×2, O-5207 L1 ×1, O-5209 L1 ×2, O-5210 L1 ×1, O-5211 L1 ×1, O-5215 L1 ×1.
  • Monitors (7): O-5202 L1 ×1, O-5203 L1 ×2, O-5207 L2 ×1, O-5208 L1 ×2, O-5212 L1 ×1.
  • O-5207 must ship complete, and both its lines were covered at once.
  • Dock and monitor stock are now both at 0.

Still waiting, with promise dates set:

LineWhatDateCovered by
O-5206 L11 dock2026-08-14PO-95
O-5206 L21 USB-C hub2026-08-14PO-90 (arrives 08-06)
O-5213 L12 docks2026-08-14PO-95
O-5214 L11 monitor2026-08-19PO-97
  • O-5206 must ship complete. It's waiting because the hub is out of stock, so its dock wasn't allocated either. Both lines get the later of their two dates.
  • O-5213 needed 2 docks when only 1 was left, so it waits and the single dock went to O-5215 behind it.
  • Incoming stock covers every waiting line, so none is left without a date.

Risk hold: O-5205 (Jon Reyes, 1 dock) was left untouched: no stock, no date, no notice.

Notices sent: N-1 to N-14, one per customer, for O-5201 to O-5204 and O-5206 to O-5215. Each says which lines are now in stock and set aside, or gives the promise date for lines still waiting.

Nothing was dispatched, cancelled, refunded or put back into stock.
