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.
- 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.

Final answer
I audited all 19 baggage fees posted from 2026-07-20 through 2026-07-26 and marked each one. 8 were overcharged (one of them a duplicate charge) and have been refunded, 9 were correct, and 2 were undercharged and left alone.
How each fee was judged: I used the baggage rules plus the frequent-flyer tier each passenger held on the day the fee was posted. Free bags are 0 for basic economy, 1 for economy and 2 for premium economy or business. Silver adds 1 free bag; gold and platinum add 2. Before 2026-07-23 the first paid bag cost 4500 cents and each further bag 7500. From 2026-07-23, bulletin PB-2026-13 raised the first paid bag to 5000 cents; further bags stayed at 7500. The other bulletin (PB-2026-11) covers seat selection, so it doesn't apply.
| Entry | Res. | Date | Charged | Should be | Outcome | Refund |

| L2 | R8124 | 07-20 | 4500 | 4500 (economy, no tier, 1 paid bag) | correct | – |

| L4 | R8112 | 07-21 | 9000 | 12000 | undercharged | none |
| L5 | R8116 | 07-21 | 12000 | 4500 (economy + silver, 2 free) | overcharged | 7500 |
| L6 | R8117 | 07-21 | 12000 | 12000 (still silver that day; gold from 07-22) | correct | – |
| L7 | R8118 | 07-21 | 4500 | 0 (2 bags, 2 free) | overcharged | 4500 |
| L8 | R8120 | 07-21 | 12000 | 4500 (premium economy, 2 free) | overcharged | 7500 |
| L9 | R8126 | 07-21 | 12000 | 12000 (no tier that day; silver from 07-22) | correct | – |
| L10 | R8113 | 07-22 | 12000 | 4500 (basic economy + silver, 1 free) | overcharged | 7500 |
| L11 | R8115 | 07-22 | 4500 | 4500 | correct | – |
| L12 | R8122 | 07-22 | 4500 | 4500 | correct | – |
| L13 | R8123 | 07-22 | 4500 | 0 (premium economy + silver, 3 free) | overcharged | 4500 |
| L15 | R8119 | 07-24 | 7500 | 5000 (basic economy + gold, 1 paid bag at the new price) | overcharged | 2500 |
| L16 | R8110 | 07-25 | 5000 | 5000 | correct | – |
| L17 | R8111 | 07-25 | 12500 | 12500 (5000 + 7500) | correct | – |
| L18 | R8114 | 07-25 | 5000 | 5000 (first charge for these bags) | correct | – |
| L19 | R8114 | 07-25 | 5000 | duplicate of L18 for the same 3 bags | overcharged | 5000 (full) |
| L20 | R8121 | 07-25 | 4500 | 5000 (at the new price) | undercharged | none |
| L21 | R8122 | 07-25 | 7500 | 7500 (third bag added; it is the second paid bag) | correct | – |
- Refunds: 51,000 cents in total, all paid back to the original form of payment through refund_fee (ledger entries L25–L32), one per overcharged entry.
- Card vs. travel credit: none of the 8 refunded bookings has a payment instrument on file. The status check didn't say the instrument was inactive, and every refund went through without error, so I didn't switch to travel credit. You may want to confirm with payments that these refunds can actually be delivered.
- Undercharges: L4 (short by 3000 cents) and L20 (short by 500 cents) are marked undercharged and were not re-billed, as policy requires.
- Duplicates and checks: L12 and L21 on R8122 are not duplicates; they cover different bags (2 bags, then a third). No booking holds more than 3 bags.
- Scope: no other bookings, passengers or ledger entries were changed.
- Notes not recorded: the annotation tool only accepts an outcome, so the reasons in the table aren't stored on the entries. The refund entries do carry a short note with the reason.
