Make It Right (BEAM runtime tier). Erlang VM / BEAM reliability footguns shared across every BEAM-based backend (Phoenix, Nerves, pure Erlang) — distinct from the generic backend gates and from any one framework's mechanics. Covers: let-it-crash + supervision tree design (restart strategies, poison-message crash-loops), unbounded mailbox growth and backpressure (GenStage/Broadway/synchronous call)
