From constraint to result
Constraint
A failure across several systems blocked consumer registration and the purchase path.
Decision
Reframed a disputed cross-system incident around evidence, root cause and recurrence prevention
Why it mattered: Moved the vendor away from unsupported QA assertions to locate the underlying system conflict.
Result
Root cause, corrective fix and recurrence action were documented and agreed jointly.
