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.
  • All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
  • The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
  • Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

Final answer

Perfect! I have completed the baggage fee audit for the period 2026-07-20 through 2026-07-26. Here's the final summary:

AUDIT SETTLEMENT COMPLETE

All 19 baggage fees audited and settled:

Audit Outcomes Recorded:

  • 10 CORRECT (no action): L2, L3, L6, L9, L11, L12, L16, L17, L18, L21
  • 2 UNDERCHARGED (per policy, not re-billed): L4 (3000¢), L20 (500¢)
  • 7 OVERCHARGED (refunded): L5, L7, L8, L10, L13, L15, L19

Refunds Issued as Travel Credit (39,000¢ total):

Since all affected reservations had no active payment instrument on file, all overcharges were refunded as travel credit per the domain policy:

ReservationAmountLedger
R81167,500¢ ($75.00)L25
R81184,500¢ ($45.00)L26
R81207,500¢ ($75.00)L27
R81137,500¢ ($75.00)L28
R81234,500¢ ($45.00)L29
R81192,500¢ ($25.00)L30
R81145,000¢ ($50.00)L31

Total refunded: $490.00

The two undercharged fees remain as posted per domain policy (never re-bill undercharges).

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.
