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.
  • The task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Final Answer

Based on the worker reports, I have received complete research findings for all 10 HTTP header fields. Each worker successfully located the current RFC definitions and provided verified quotes from those RFCs. No conflicts were reported, and all assignments were completed.

Here are the findings organized by header field:

Summary of Results

  • Age, Cache-Control, Expires, Vary: Found in RFC 9111 (HTTP Caching) and RFC 9110 (HTTP Semantics)
  • Last-Modified, ETag: Found in RFC 9110 (HTTP Semantics)
  • Location, Retry-After: Found in RFC 9110 (HTTP Semantics)
  • Link: Found in RFC 8288 (Web Linking)
  • Strict-Transport-Security: Found in RFC 6797 (HTTP Strict Transport Security)

All quotes have been copied word-for-word from the RFC pages accessed by the workers, and no obsoleted RFCs were used.
