KNOWLEDGE CARD / README
Portable policy knowledge for local retrieval.
Good observability connects a user symptom to a likely cause and a next action.
Use metrics for trends, logs for event detail, and traces for causal paths.
Bound cardinality and redact secrets before telemetry leaves the process.
Intended use
Grounding engineers and on-call assistants while instrumenting services or narrowing production failures.
Out of scope
This pack does not define a vendor query language, collect telemetry, or replace service-specific dashboards and runbooks.
