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.
