Some factories run with the lights off.
A lit factory keeps a human reading the diff before it ships. A dark factory ships code no human has read, verified only by other machines. The difference is not a tier of sophistication — it is a physical claim about where reading happens. In a dark factory: nowhere.
The lit factory
Agents do most of the building. Judgment moves upstream — to the plan, the design, the architecture — and a person still reads what comes out.
The dark factory
Throughput appears to break the sound barrier, because the missing step was in everyone's way. The costs are buried, and they arrive late.
The seven stations
Read in order and the argument builds: what the pieces are, what the word “dark” actually claims, what it costs, why verification rather than generation is the constraint, how the environment around the model gets engineered, and then the part you can act on — deciding, loop by loop, where each switch goes.

Two kinds of page
The stations carry the durable argument — the parts that should read the same in a year. Every fact that will not survive a year lives somewhere else: in a registry, with the date it was true and the source it came from.
- The landscape — who is running what, at which level of autonomy, with every figure dated and stamped.
- The case study — four factories run by one person, including what they got wrong.
- The playbook — three stages, each with a condition for moving on and a condition for stopping.
- The sources — every citation, its evidence tier, and what that tier permits you to conclude.
That separation is the point of the arrangement rather than a filing convenience. Model names, benchmark scores and funding rounds change monthly, and a chapter that hard-codes them rots without anyone noticing. Here a figure is corrected in one place, and the revision is recorded where you can see what changed and why.
