Coverage: pp.1–92 are described from the supplied copy; pp.93–96 Appendix E are unavailable and cannot be summarized. A version conflict exists between the p.21 v3.1 reference and v3.2 change log; resolve before relying on severity activation.
Layered contents: Front matter pp.1–3—version authority. I Scope/definitions pp.4–9: 1.1 purpose; 1.2 covered services; 1.3 severity levels—mandatory activation vocabulary. II Roles pp.10–18: authority and handoffs. III Activation pp.19–37: detection; severity; activation; p.24 flow; pp.30–31 first-hour checklist. IV Playbooks pp.38–55: select by event, including SaaS pp.46–49 if locator confirmed from original. V Communications pp.56–67: channels/templates, with legal caveat. VI Recovery pp.68–75: criteria, evidence, closure. VII Exercises pp.76–84. Appendices pp.85–92: contacts, priorities, RTO/RPO, evidence log. Appendix E pp.93–96—missing, mandatory warning.
Incident lead 10-minute route: p.1–3 version check (1 min) → 1.2/1.3 pp.5–9 (2 min) → authority pp.10–14 (2 min) → activation flow p.24 and first-hour table pp.30–31 (4 min) → missing Appendix E warning (1 min). Checkpoint: confirm current severity authority and contacts; do not execute from summary. Service owner 25-minute live route: same prerequisites, SaaS playbook original, communications conditions, recovery criteria, Appendix C definitions then RTO table, and Appendix E warning. Stop if severity conflict affects activation or legal notification is needed.
Deep study: session 1 Parts I–III plus conflict log; session 2 playbooks/communications with scenario tracing; session 3 recovery, exercises, and appendices with an evidence-log practice. Lookup: contacts A, service priority B, RTO/RPO C before table, evidence template D, communications templates Part V. Legal/safety wording always requires the original; missing E must be obtained from the document owner.
