| Provider calls | Three main observations; one logical worker in the miss arm |
| Automatic retries | None |
The frozen natural task and quality oracle were identical across frontier direct, routed miss, and proof-backed hit arms. The miss could use at most one worker; the hit had to remain cache-only.
All final responses completed and passed the quality oracle.

The miss published one validated implementation artifact. The hit reused the
same artifact through an authoritative CoverageHit, with validation and
sufficiency certificates, positive observed reuse economics, zero stale or
contradicted evidence, and worker_avoided=true.
Observed reductions for this sample:
- routing: 74.41%;
- cache relative to miss: 57.24%;
- end-to-end relative to direct: 89.06%.
The source remained clean. Focused-test execution was not required by the task.
This validates the current live route → worker → validation → publication → zero-worker reuse path for one pinned location task. It does not establish a confidence interval, multi-task behavior, other routes, or general savings.
