# Nine months without a rewrite > Source: > Published: 2026-05-27 21:19:08+00:00 When was your company's MVV last rewritten? At 25h, it has stayed untouched for nine months. Not because it is unfinished. Nine months. That is how long 25h has run on the same MVV. The words written on June 11, 2025 still sit where they were placed. Same location, same shape. The fact of not rewriting is itself worth writing down. June 11, 2025. In the first week of founding 25h, the first piece of work was to formulate the MVV. I described my background, my temperament, and my values to an AI, and we shaped the language through dialogue. Mission, vision, values. It was decided that same day. *"Efficiency for the sake of preserving margin."* *"Margin for the sake of working on what is essential."* Something settled the moment those words appeared. The journal records that. It also records the response — *"That landed deeply."* That core has not shifted since. May 2026 looks at it and finds the same shape. That day, "systematization" was proposed as one of the values. I caught the discomfort immediately, and put it into words. *"Systematization is only one means."* *"It is not a value."* *"Whether to systematize, stop systematizing, or change it — all of them are means."* This correction mattered. Being sensitive to the granularity of values. Refusing to conflate means and ends. That itself was already an expression of the 25h thinking style. In the final values, the word "systematization" does not appear. What remains instead is an orientation toward the freedom of choice. After the MVV was formulated, many efforts unfolded. We named the 25h production process. We hypothesized a management team composed only of AI. We deepened the idea that margin is not consumed but produced. We defined failure as anything short of fatal. Each time, the work was checked against the MVV. *"Does this align with the Mission?"* *"Does this contradict Time is Autonomy?"* After the check, every effort connected back to the MVV. There is a narrative that says the MVV evolved over nine months. A story of refinement through trial and error. It is half true. There was refinement of expression. Each concept was extracted as an atomic note. A guardian clause was added. Operation as a judgment standard began. But the core did not move. What was put into words on June 11, 2025 still runs today. *"Efficiency for the sake of preserving margin"* points in the same direction as the highest principle of 25h now. The confirmed MVV file was created on February 20, 2026. This was not the day the MVV was completed. It was the day on which the MVV had been sufficiently demonstrated to function as a judgment standard. Not declared first as a manifesto, then enforced. Verified through actual judgments, then formalized. That sequence matches the design style of 25h. The guardian clause was added on the same day. *"Does this produce someone's hour?"* That question became the gate every output passes through. The MVV graduated, on that day, from thought to operational rule. There is value in the core of the MVV not moving. As derived efforts multiply, the consistency of judgment is what gets tested. *"Why am I doing this?"* *"Is this 25h-like?"* Those questions need a place to return to. That place is the MVV. Expression evolves. It gets decomposed into atomic notes, structured as a wiki, embedded into each agent. But the core stays still. If the core moves, every derived effort wavers. Because there is an axis that does not move, derivation can stay free. How many years ago was the core of your own thinking put into words? And has it changed since.
