Observe the cells.
Each task and tier pair retains run count, pass rate, retries, spend, and cost per successful run.
Compile observed pass rates, retries, and cost per pass into the cheapest task-tier routes that clear your reliability gate.
Eval cells appear here.
Each task and tier pair retains run count, pass rate, retries, spend, and cost per successful run.
A cheap tier cannot receive a task class when its observed pass rate misses the explicit reliability gate.
The compiler chooses the lowest cost per pass only after reliability eligibility is established.
