Write the tasks the frontier still fails

A task only earns its place if models fail it honestly. The pipeline measures that for you and says exactly why a submission did not qualify, with the file and the line.

What the pipeline does for you

Difficulty is measured for you
Gate 5 runs your task across the matrix and reports the pass rate. You do not have to guess whether it is hard enough.
Findings, not a rejection
Each refusal carries a remediation, so a failed check names the fix rather than only the failure.
A real reviewer
Gate 6 requires two failing trajectories to be opened by someone who is not you, recorded as access events.
Paid on accept
Acceptance enqueues the payout in the same transaction as the verdict, so the two cannot disagree.

A task only earns its place if models fail it honestly, and the pipeline measures that for you rather than asking you to guess.
