The Problem with Stitched-Together Stacks
Most businesses run on duct tape. Zapier here, spreadsheet there, manual process everywhere.
LeanOS treats business operations as a categorical pipeline: SPEC → BUILD → VERIFY → GEN. Every operation is a morphism. Every integration is a functor. Composition is guaranteed by construction.
Why This Matters
# Traditional: hope it works
def process_order(order):
try:
validate(order)
charge(order)
fulfill(order)
except Exception as e:
# good luck debugging this
log(e)
# Categorical: composition guarantees
pipeline = (
Validate[Order, ValidOrder]
>> Charge[ValidOrder, PaidOrder]
>> Fulfill[PaidOrder, CompletedOrder]
)
# Type-level proof that the pipeline is valid
The second version eliminates an entire class of runtime errors at the type level.
