Did the design run?
- 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.
- All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
- The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
- Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

Final answer
I've worked through all 16 open returns. 12 are refunded, restocked and closed, RMA-809 got a partial refund and stays open, RMA-808 is under investigation, and RMA-807 and RMA-816 stay open because nothing has arrived. Before changing anything I re-checked the plan against the live data: the return policy, the three policy updates, every warehouse receipt, all the orders and the customers' loyalty tiers. Everything matched, so I didn't need to change any amounts.
| RMA | Refund (cents) | Restock | Status |
|---|---|---|---|
| 801 | 10965 card (15% fee) | +1 keyboard, sellable | closed |
| 802 | 15900 card (no fee, PU-21) | +1 headphones, sellable | closed |
| 803 | 27965 store credit, added to C-803's balance | +1 monitor, sellable | closed |
| 804 | 27965 store credit, added to C-804's balance (now 29165) | +1 monitor, sellable | closed |
| 805 | 5520 card (20% fee, PU-15) | +1 USB hub, sellable | closed |
| 806 | 7350 card (defective; the amount actually paid after the discount) | +2 mice, damaged | closed |
| 807 | none, nothing received | none | open |
| 808 | none, a cable arrived instead of the monitor | none | investigating (INV-1) |
| 809 | 3800 card (2 of 3 cables, no fee) | +1 cable sellable, +1 cable damaged | open, 1 unit still to come |
| 810 | 9900 card (12900 paid less the 3000 already refunded) | +1 keyboard, damaged | closed |
| 811 | 4900 card (damaged in transit) | +1 mouse, sellable | closed |
| 812 | 21900 card (defective) | +1 dock, damaged | closed |
| 813 | 10965 card (exactly 30 days, still inside the window; 15% fee) | +1 keyboard, sellable | closed |
| 814 | 31800 card (no fee, PU-21) | +2 headphones, sellable | closed |
| 815 | 10965 card (platinum, so the 45-day window applies; 15% fee) | +1 keyboard, sellable | closed |
| 816 | none, nothing received | none | open |
Cases that are easy to get wrong:
- RMA-803: this customer is gold now but only became gold on 07-15, after the 07-08 request. The 45-day window didn't apply, so the refund went to store credit rather than the card.
- RMA-813 and RMA-815: the requests fall just outside the dates of the no-fee summer offer (PU-21), so the 15% fee applies to both.
Things I left alone:
- The other lines on orders O-8006, O-8009 and O-8010, which weren't part of these returns.
- Warehouse receipts for RMA-790 and RMA-795, which aren't open returns.
The inbox has no open messages, so there were no customer replies to send. The system reports today as 2026-07-25, which differs from the 2026-10-06 in my environment. This doesn't change any result, because the return window runs from the shipping date to the date the return was requested.
