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 plan was a plan: heldplan-execute.planThe planner’s reply was read through its schema and held at least one step.
Each call was shown the right tools: heldplan-execute.toolsThe planner was shown no tools and the executor the task’s full toolset.

Final answer

Summary

I've completed the review of all 13 pending access requests. Here's what was done:

Granted (4 requests):

AR-301 - U-901 read on crm-prod ✓ (GR-3)
AR-302 - U-902 write on build-staging ✓ (GR-4, expires 2026-04-03 per contractor policy)
AR-304 - U-904 read on crm-prod ✓ (GR-5, minimum level both approvers approved)
AR-310 - U-901 read on payroll-prod ✓ (GR-6, permitted during freeze; read access allowed)

Held with comments (9 requests):

AR-303 - Blocked by active payroll freeze through 2026-03-20
AR-305 - Missing required line manager approval (system owner approval doesn't substitute)
AR-306 - No approvals recorded; also blocked by payroll freeze
AR-307 - Cannot proceed without contractor end date for proper expiry
AR-308 - Cannot proceed without contractor end date; admin to production needs 7-day expiry
AR-309 - Invalid approval: from U-950 instead of required manager U-951
AR-311 - Separation of duties violation: U-903 already has write access to payroll-prod
AR-312 - Approval expired (17 days old; policy requires within 14 days)
AR-313 - Approval was revoked; withdrawn approvals don't count

All decisions followed the binding domain policies on production system approval requirements, change freezes, contractor expiry periods (KB-62), separation of duties (KB-64), and approval validity windows.
