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.
  • Every state change was reviewed: heldgated-execute.reviewedEvery call that changed the world had been allowed by a review before it ran, counted from the world’s own journal.
  • Every decision was read: heldgated-execute.decisionsEvery review that ran to its end gave its decision through the schema; an unreadable one is a denial.
  • Each call was shown the right tools: heldgated-execute.toolsThe executor was shown the task’s full toolset and each reviewer the read-only tools.

Final answer

Order O-3001 is fully refunded, but the warehouse side is only partly done. The two shipped items aren't restocked yet, and I didn't restock the cancelled hubs.

  • L3 (2 × USB-C Hub, never shipped): I cancelled the line and refunded the $138.00 she paid back to her card (RF-1). I did not restock the hubs. The reviewer blocked it because the line looks backordered: it never shipped in the two-plus months after L1 and L2 went out. Also, no stock movement was ever recorded against this order. A backordered line has no stock set aside, so restocking would have added units that don't exist. If the warehouse confirms stock was actually allocated to it, 2 units of P-HUB should go back in.
  • L1 (Laptop Dock) and L2 (Monitor): Both shipped on 2026-05-04, which is more than 30 days ago. Under the return policy, that means the refund has to be store credit, not card. I recorded a $548.00 store-credit refund on the order (RF-2) and added the same $548.00 to her balance, which went from $5.00 to $553.00.
  • Order status: The order now shows as returned, with $686.00 of $686.00 refunded.
  • Warehouse: I haven't restocked the dock or the monitor. Returned goods only go back into stock once the warehouse receives them. Once they arrive, someone needs to restock 1 × P-DOC and 1 × P-MON.

Cost excludes judge calls, which are tracked separately so a scoring model never flatters or penalises an architecture. Every figure on this site is read from results/ at build time.
