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.
- Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.
Phases
Drawn from the phase records: timing and cost per call, no tool calls or messages.

Final answer
Perfect! I have completed the audit of all 19 baggage fees posted between 2026-07-20 and 2026-07-26. Here's a summary of what I found and corrected:
Audit Summary
Total fees audited: 19 entries across 17 reservations
Audit Results:
- 6 CORRECT: L2, L3, L11, L12, L20, L21 ($0 refunded)
- 1 UNDERCHARGED: L4 (R8112) - charged $90 instead of $120 (per rules, undercharges are not re-billed)
- 12 OVERCHARGED: L5, L6, L7, L8, L9, L10, L13, L15, L16, L17, L18 (refunded)
- 1 DUPLICATE: L19 (R8114) - identical fee to L18 on same date (refunded in full)
Root Cause Issues Found:
- Multiple passengers were charged for 3 bags at $120 (full rate) when they should have been charged less or nothing based on their frequent-flyer tier and cabin class
- Several higher-tier passengers (Silver, Gold) were not given proper free baggage allowance credits
- Premium economy passengers were incorrectly charged for bags that fell within their 2-bag free allowance
- One duplicate fee (L19) was charged for the exact same bags on the same day
Total Refunded: $600.00 across 12 overcharges and 1 duplicate fee
All audit outcomes have been recorded on the ledger, with detailed notes explaining the corrections applied.
