The DB-only audit_knowledge_graph can't see guests running in Proxmox that
have no entity, or entities whose pve_id is no longer live — the drift that
the stray test LXCs were a symptom of. discover_infra_drift enumerates running
guests via pct/qm list on every proxmox host (over the same SSH/pct path the
checks use) and diffs against the DB: returns missing (live, no entity) and
ghost (DB, not live). Read-only.
Companion to audit_knowledge_graph; the skill now runs both and treats the
remaining checks (misplaced parent, undeployed scripts, seed drift) as manual.
Adds audit_knowledge_graph (MCP tool) and GET /api/v1/audit/drift (endpoint)
backed by a shared internal/audit package. One pass surfaces the structural
gaps an operator otherwise finds by accident: orphan check entities, checks
targeting deprecated/destroyed entities, probes stuck down/unknown, unmonitored
declared types, and live edges pointing at destroyed targets. Each finding
carries a suggested remediation runbook. Read-only and safe to run unattended.
Ships the knowledge-graph-audit skill (SKILL.md + seeded runbook) that
interprets the report and routes findings to the lifecycle runbooks.
