The book is the argument; this file is the record it argues from. Ostermill is a designed composite: no real company, no real people, every number derived from one internally consistent canon. Sixteen weeks from a Friday demo to production, then governance that never ends. Five phases, each with its meetings, its paperwork, and its evidence. Start anywhere; every surface links back here.
Ostermill Industrial Supply, Columbus. A distributor, not a lab. The people who will run this project, introduced as they were on day one, with no project record attached.
A four-hour demo closes a question nobody had finished asking. Deciding means reopening it: a counted week, three prototypes built badly on purpose, a stopping condition written before the run, and a go memo that refuses to annualize.
What may it do, and who answers. Two briefs written from what the prototypes demonstrated, the walls with named owners, and an approval screen that carries the reason the agent stopped, because Ruth kept five words in a sentence.
Does the evidence cover the authority. Twelve graded cases, ten runs each, three eval versions: 79, 83, 86 percent, with one adversarial case shipped named rather than fixed. Run the bench yourself; the runs are recorded, the sampling is yours.
Production is what the eval promised until 21 July, when it is not. One send, five days after a death, found by a spot check fourteen days later. The instruments, the incident, and the agent itself, replayed step by step over the recorded runs.
Is it still the product we approved. A rung refused and later earned, a kill number retired while it was being met, an authority revoked in June, and signatures that outlive signers. The calendar carries the whole year.
