Reconcile an inbox against responses that arrive out of order
Measured at 50% over 6 counted trials, which is inside the band gate 5 admits. The breakdown below says which model that figure came from.

3 of 6 counted trials met the reward threshold.
Each cell is one agent against one model, run for the same number of attempts.
Trials that produced no reward. Counted separately and never in the rate above.
Every attempt this round started, including the ones that errored before a reward.
What each model did
One row per agent-and-model cell of the round that produced the figure above. The bar is passes over counted trials.
The table scrolls sideways.

A cell with no passes is not a broken task: it is the point of one. Gate 5 admits a task only when the full matrix lands between 10 and 60 percent, so a set that every model cleared would have been rejected for being too easy before it reached this page.
The task
A desktop inbox shows a change the moment somebody makes it, while the request is still in flight, and responses come back in whatever order the network gives them. The list has twice jumped backwards: an older response restored a finished row, and a change that failed stayed on screen as though it had worked.

- Declared tier
- medium. The tier is the author's declaration and it decides which band passes: a hard-tier task may legitimately sit under 10 percent, where a standard one may not.
- Languages
- python
- Harbor package
- prudo/inbox-revision-fence. The name a licensed copy carries, so a run of it is traceable back to this row.
- What a licence includes
- The graded task, its environment and verifier images pinned by digest, and the trial record behind the figures on this page.
- What stays with us
- The instruction, the test suite and the reference solution. Publishing those would retire the task, because a measurement you can read the answer to is not a measurement.
