Minimal Reproduction

Turn an observed failure into something that can be run again and answers with an exit code. Driving the whole system to watch a symptom is slow, hard to repeat, and produces evidence nobody can re-run.

Two levels

A working reproduction exists to find the problem and to test a candidate fix. It only has to fail reliably, run fast, and be honest about what has actually been verified. It stays where the work is and is disposable. See references/working-repro.md.

A demonstration reproduction is an artifact built for a reader who has none of this context. It shows the mechanism, the fix when there is one, and nothing else, and it is designed to make that mechanism obvious rather than to recreate the original symptom. See references/demonstration-repro.md.
