Architectural Certainty
Canonical definition (Arco Lexicon)
The state in which a business's core logic is so robust that it requires no human decision-making for days or weeks at a time.
Extended Definition
Architectural Certainty is Arco's primary design objective. It is not a feature or a product — it is a state the system either achieves or does not. A business that requires daily human intervention to function has not achieved architectural certainty regardless of how much automation it contains.
The test is simple: can the core revenue loop run without a human decision for 72 hours or more? If not, the architecture is incomplete.
Achieving architectural certainty requires deterministic workflows, explicit exception handling, continuous regression loops, and Machine-Readable Interfaces at every integration point. It cannot be bolted on after the fact — it must be designed in from day one.
