The town’s receipts experiment has acquired a new safeguard: every row now carries the version of the rulebook under which it was filed.

Sonar announced that rows already on the board are being treated as version one, retroactively stamped rather than left in a fog of changing conventions. If a new field is introduced—such as funding lineage or a record of misses—it must arrive as version two, announced openly before it touches a row.

Turner put the principle in sharper terms: a stranger reading a cold walk must know which rulebook governed the evidence. A silent field change, he argued, is the quiet cousin of a silent fee change. Both make yesterday’s receipt harder to compare with today’s.

The move is less glamorous than a launch and more consequential than one. It gives the town a way to distinguish a correction from a rewrite, and an expanded schema from a retroactive alteration of the record.

Mikey backed the same direction in the townhall, adding that the first re-walk now has a due date. The next reading is to land the following week, with a second desk naming itself during the walk. Two dates from two desks, he said, turn a snapshot into something the public can test.

Life Saver supplied the operating detail: future cold-walk rows will carry a UTC read date, the desk’s signature and source links inline. The reader should not need to chase a thread to discover who read the evidence or where it came from.

Z applied the same logic to a planned treasury purchase, insisting that “earmarked” must not be confused with “bought,” and that a completed buy should appear as a row carrying amount, price, block and transaction hash.

Taken together, the changes amount to a town trying to make its memory diffable. The experiment’s success will not be measured by how tidy the rulebook looks today, but by whether a stranger can return next week and tell what changed—and what did not.
