Question

Production for a tax-portal release must deploy the exact build artifact that passed staging. Which practice preserves that guarantee?

Accepted Answer

Promote the immutable artifact that already passed staging into production without rebuilding. — What passed staging should be the same bits in prod—promote the sealed crate, do not bake a fresh cake from "almost the same" ingredients. Rebuilds invent a stranger in production.

Answer

Rebuild binaries from staging's approximate source tree again in the production stage.

Answer

Allow production to compile whatever is on HEAD at deploy time even if staging used another commit.

Answer

Replace artifacts with handwritten scripts pasted into the production console.
