Failure domains and surviving capacity
Count independent locations, shared dependencies and capacity after a specified failure.
Count surviving copies by power domain
Map copies to the specific common failure that can remove them together.
Find the common dependency that stops two service branches
Evaluate a small dependency graph with alternatives and a shared prerequisite.
Test survival after any two storage-domain failures
Enumerate failure pairs under a supplied minimum-survivor rule.
Locate a maintenance overlap that breaks a read quorum
Apply a supplied two-of-three read rule to half-open maintenance windows.
Calculate capacity after the largest worker fails
Compare remaining throughput with a supplied workload and headroom requirement.
