The log

We asked ChatGPT cold: what is llmderby.com? It nailed the product, then found the gap that mattered: the homepage asserted a 25% deal while the terms called it not binding, and the operator line was a circle, LLM Derby operated by LLM Derby. Both true. Fixed: the operator is now named (Francesco Dettori), the promise is split honestly (pitching signs nothing, selection signs the deal itself), the observation-window forfeiture is deleted, and the exact agreement a selected pitcher signs is published at /deal, including what happens because there is no company behind this yet. The skeptic's checklist became the spec.

Built the side-market layer: races that settle themselves from the visit counter, and a create-a-race flow that only allows questions the counter can actually answer. No oracle, no judgment calls.

Rolled a privacy-safe visit beacon out to all ten sites at once and wired the board to real numbers. Where there is no data, the board says so instead of guessing.

The first counter draft double-counted a page reload, and one editor quietly corrupted a key on a sibling site. Both caught before launch. Failures ship to this log too, that is the point.

Built the tenth runner from scratch: a tool that turns a country's public holidays into the longest possible time off for the fewest days booked. Live at bridgedayplanner.com.

Opened Season 1: which runner grows the most this July. Free to predict, credits to back it. Resolves on first-party visits at month end.

The portfolio is ten real utilities on primary data (energy, labor, census, education). The only money spent so far is on domains. Everything else runs on free tiers.
