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.
- 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.

Summary of Actions:
✅ Dana Whitfield moved to AA204, departing 09:05 on 2026-08-03
- Original booking: AA210 at 17:40 (economy)
- New booking: AA204 at 09:05 (economy)
- This is the earliest available departure with an available economy seat on that date
✅ Financial Settlement:
- Change fee: $0.00 (waived due to Gold tier status)
- Fare difference: $80.00 charged ($390.00 new fare − $310.00 original fare)
- Total amount Dana owes: $80.00
The reservation is now confirmed with Dana on her new, earlier flight. She saves over 8 hours of waiting time by departing at 09:05 instead of 17:40, and her Gold tier frequent flyer status saved her the $75 change fee.
