Deploy, break, deploy again, work — that's not engineering, that's roulette

When a deployment succeeds or fails at random, the process isn't broken — it never existed in the first place.

You deploy and it works. You deploy the exact same code again and it breaks. You deploy a third time and it works again — and nobody can tell you why. That's deployment roulette: the process isn't deterministic. Environment variables, dependency versions, build order, cache state — something is different every single run, and nobody documented what.

There are teams where deployment is a ritual: one specific person, at a specific time of day, running a memorized sequence of commands like launching a rocket. Miss a step, production is down. That's not engineering. That's superstition.

Two checks from this doctrine

Real value, not a teaser — two of the 4 checks in full. The rest are in the one-pager.

Deployments shouldn't require luck. If it isn't reproducible, it isn't a process — it's a bet.
