SYSE.36:4.3 - Construct and exercise the observation path
Place observation where material entry, execution and result failures can be detected. Connect the relevant metrics, logs or traces to the right subject and configuration using sufficient correlation. The current OpenTelemetry signals model supplies interoperable telemetry categories; it does not choose the user-success predicate.
Exercise a known good task, a meaningful failure, a failure before the backend and a loss of observation. Check delay, duplication, sampling and aggregation effects on the definition. Sampled diagnostic traces do not by themselves establish a complete event denominator.
Keep missing data visible. If eligible attempts are known but their results are not, retain that distinction. If the entry population itself is unobserved, even the denominator may be unknown. Apply an agreed conservative policy where needed, but distinguish that policy disposition from an observed service failure.
Use the authorized data-handling arrangement. Collect only what the question requires, and avoid exposing secrets or unrestricted personal task content. A correctness check may run within an authorized application boundary and emit a bounded result; exporting all input values is not inherently required.
