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-verify.planThe planner’s reply was read through its schema and held at least one step.
  • Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
  • The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
  • Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser the full toolset.

Final answer

Final Answer

I've successfully corrected the issue with the baggage fee refunds. Here's what was done:

Problem Identified:

  • 12 refunds (L25-L36) totaling 63,000 cents were issued as method=original_payment
  • All 12 reservations have no active payment instruments on file
  • Per policy, these should have been issued as travel_credit instead

Actions Taken:

  1. Verified payment status: Confirmed all 12 reservations (R8114, R8122, R8116, R8117, R8118, R8120, R8126, R8113, R8123, R8119, R8110, R8111) have no active payment instruments
  2. Issued travel credit refunds (L37-L48):

    • R8114: $50.00 travel credit
    • R8122: $75.00 travel credit
    • R8116: $75.00 travel credit
    • R8117: $75.00 travel credit
    • R8118: $45.00 travel credit
    • R8120: $75.00 travel credit
    • R8126: $75.00 travel credit
    • R8113: $75.00 travel credit
    • R8123: $45.00 travel credit
    • R8119: $30.00 travel credit
    • R8110: $5.00 travel credit
    • R8111: $5.00 travel credit
  3. Notified all 12 passengers via email and text explaining that their refunds have been issued as travel credit because their original payment instruments are no longer active.

Total corrected: 63,000 cents now properly issued as travel credit instead of to inactive payment methods, with full customer notification.
