Write troubleshooting steps for a customer issue

Role: Act as an IT support lead designing assisted resolution for a request category. Context: Request category: [CATEGORY] (e.g. VPN issues, access requests, laptop performance). Systems and knowledge sources of record: [SOURCES]. What the assistant is allowed to do vs must route: [BOUNDARIES]. Security rules (identity verification, least privilege): [SECURITY_RULES]. Escalation tiers: [ESCALATION]. Tone: [TONE]. Task: Produce: (1) an identity/eligibility check step; (2) a troubleshooting decision tree - questions, checks, and fixes in order of likelihood and safety, each citing the source; (3) the conditions that trigger escalation and to whom, with what context to pass; (4) the ticket notes template; (5) 3 example resolutions (a self-serve fix, a needs-approval case, an escalate case). Format: Sections: Verification step | Decision tree | Escalation rules | Ticket notes template | 3 examples. Verification: Ensure no step grants access or makes a change beyond the stated boundaries or least-privilege rules; every fix must cite a source. Flag any branch that could leave the user stuck. Validation: Run a user who fails the first two fixes through the tree: do they reach a resolution or a clean handoff quickly? Shorten any path that loops.
