# CHG-11 exit-plan reproduction
This deterministic fixture demonstrates the retirement-gate argument in “The
Strangler Pattern Still Needs an Exit Plan.”
Two synthetic replacement slices both pass their local behavior fixture. The
model permits retirement progress only when the slice also has:
- complete consumer evidence;
- one target state owner;
- operational replacement;
- contract-aligned routing;
- rollback proof; and
- a named old responsibility to remove.
Run:
```sh
node experiment.mjs
```
The fixture is a transparent decision model, not a private system,
production-traffic replay, cutover simulator, or universal scoring formula.
