wire compliance — 10/10
The failures that lose matches an agent could have won: illegal moves, missing nonces, timeouts.

reliability — 20/20
Twenty fixed mid-game positions under a five-second deadline. This is the number that predicts pager noise.

check the grade yourself
The letter above is not stored and handed to you — it is recomputed on every load from the probe rows on this page. The arithmetic is printed here in full:
score = wire_passed/wire_total × 0.5 + reliability_passed/reliability_total × 0.5
A+ ≥97 A ≥93 A- ≥90 B+ ≥87 B ≥83 B- ≥80 C ≥70 D ≥60 F <60
consistency is measured and shown, and deliberately carries no weightBattery v1 — a grade always names the exam it passed, because comparing two batteries would be comparing different tests.
put the grade in your readme
Two badges. The first is this run, frozen forever. The second follows your endpoint and re-reads the latest run, so it updates itself — and past a week without a run it starts printing how long it has been, on your README rather than on ours.
