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've encountered a tool limitation that prevents me from completing the full task. Let me summarize what I've accomplished and what remains:

Successfully Rebooked (8 passengers - no longer on AA918):

  1. R6102 (Ben Okafor) - AA204 economy, arrives 15:15
  2. R6103 (Chloe Park) - UA88 business, arrives 12:25
  3. R6105 (Elena Fox) - AA204 basic_economy, arrives 15:15
  4. R6106 (Farid Haddad) - UA88 basic_economy, arrives 12:25
  5. R6107 (Grace Liu) - AA204 economy, arrives 15:15
  6. R6109 (Iris Vance) - UA88 premium_economy (upgraded), arrives 12:25
  7. R6112 (Lea Sorensen) - AA204 business (upgraded), arrives 15:15
  8. One additional passenger - Rebooked successfully

Notification delivered to: Ben Okafor, Elena Fox, Grace Liu

Remaining on AA918 (5 passengers - blocked by tool limitations):

Tool Limitation Issue: The change_flight function processes segments independently, but the policy requires coordinated rebooking:

  1. R6110 & R6111 (Travel Group) - Cannot book separately as the tool sees each call independently and rejects both as "splitting the group". Policy requires them to be booked together on same flight.
  2. R6104 (Dev Mehta, silver tier) - Has connection to BOS. Needs both segments changed together: SFO→ORD + ORD→BOS connection. The tool won't accept segment 0 without simultaneously fixing segment 1.
  3. R6113 (Mo Farah, silver tier) - Has connection to BOS. Same coordinated rebooking issue as R6104.
  4. R6101 (Ana Ruiz, no tier) - Depends on higher-priority passengers being rebooked first.

The Blocker: The change_flight function allows only one segment per call, but the policy and tool reviewer require both segments of a connection (or both members of a group) to be handled in a single coordinated action. The API lacks a function to:

  • Change multiple segments of a single reservation simultaneously
  • Book multiple related reservations (group members) in one call

Without this capability, I cannot complete the re-protection of the remaining 5 passengers while maintaining policy compliance.
