Error handling that degrades quietly — such as returning zero-vectors instead of raising — and the downstream data corruption it causes.

A one-qubit circuit optimised to nothing in Qiskit 2.5.0, fixed in 2.5.1. The durable lesson is that a simulator handing back a clean number is not a passing test.

One developer's day-one postmortem is really a dependency inventory: a single third-party call sat under every write and read path, and the fix moved the dependency rather than removing it.
