Why do my WebAssembly modules go dark the moment they enter production?

WASM is now a real deployment target at the edge, in serverless, and in plugin sandboxes. Container workloads have had OpenTelemetry, Prometheus, and structured logging for years; WASM workloads running under WASIp3 hosts do not emit guest-level spans by default and require deliberate instrumentation wiring that most frameworks omit. Stack traces in production failures reduce to binary addresses because DWARF debug info is stripped at build time and source maps do not survive most deployment pipelines. Operators cannot set up the same alerting and dashboards they use for containers because there is no standard way to get telemetry out of a running WASM module without modifying the guest code itself.
