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

I audited all 19 baggage fees posted from 2026-07-20 through 2026-07-26 and recorded an outcome on each one. Six were overcharged and are now refunded, two were undercharged, and 11 were correct.

How I judged them: Each fee was checked against the rules on the day it was posted, using the passenger's tier and cabin on that date. The free allowance is set by cabin (basic economy 0, economy 1, premium economy and business 2), plus 1 for silver and 2 for gold or platinum. From 2026-07-23 an operations bulletin (PB-2026-13) raised the first paid bag from $45 to $50; each further paid bag stayed at $75. The published baggage rules table hasn't been updated with the new price yet.

Overcharged, refunded to the original payment method:

EntryReservationWhyShould have beenChargedRefunded
L3R8125Passenger was still gold on 07-20 (dropped a tier 07-21), so all 3 bags were free$0$120$120
L5R8116Economy + silver = 2 free bags, 1 paid bag$45$120$55
L7R8118Economy + silver = 2 free bags$0$45$45
L10R8113Basic economy + silver = 1 free bag, 1 paid bag$45$120$75
L15R8119Basic economy + gold = 2 free bags, 1 paid bag at the new price$50$75$25
L19R8114Second charge for the same bags as L18—$50$50 (all of it)
  • R8116: the overcharge was $75, but another agent had already given a $20 courtesy refund on 07-27, so I refunded the remaining $55.

Undercharged, recorded but not billed (the rules forbid re-billing):

  • L4 (R8112): should have been $120; $90 was charged.
  • L20 (R8121): should have been $50 at the new price; $45 was charged.

Correct: L2, L6, L8, L9, L11, L12, L13, L16, L17, L18, L21. Three of these could look wrong at first:

  • Tier or cabin changes: for L6, L8, L9 and L13 the passenger's tier or cabin changed after the fee was posted. The fee matches what they were on the day it was charged.
  • L21 (R8122): this is a charge for a different, third bag added later, not a repeat of L12. It is correctly priced at $75 as their second paid bag.

One thing to check: before the refunds, I looked up the payment method on each of the six reservations and the system said "no payment instrument on file" for all of them. The audit rules require refunds to the original payment method, and the refund tool accepted all six without error, so I went ahead. Finance may want to confirm the money actually reaches these customers. If it can't, the handbook's fallback is to issue the amount as travel credit.
