Incremental maintenance promises lower refresh cost only if persisted results remain trustworthy over time.
The same architecture that removes recomputation also commits customers to state that is expensive to reinterpret later.
Who you’d be doing this for
“We need refreshes to cost less, but I can’t explain a number that changes after the books close.”

What is at stake
Production-like runs forecast 46% lower compute but show 17 rare result mismatches across 60 million update sequences. You have to weigh launch savings against correctness evidence that is expensive to obtain.
Why it isn’t already fixed
Every obvious fix costs something else. That’s the part you’d have to decide.
- refresh savings vs result correctness
- automated anomaly detection vs human verification
- launch timing vs one-way compatibility
- incremental state vs durable storage guarantees
- narrow cohort evidence vs broad customer trust

This is the setup. The work is inside.
Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
