Worksheet v0.2.0

Worksheet v0.2.0

The book grows from 10 to 12 chapters, 27 to 30 flows, and appendices A–D to A–E,
and widens its audience from senior/staff to senior through principal.

Factuality pass (#5)

15 confirmed errors fixed across all chapters — scheduler percentageOfNodesToScore
semantics, controller-runtime rate-limiter behavior, ReplicaSet vs StatefulSet
replacement timing, owner-reference scope rules, SSA field-release semantics, and more.
Every version-sensitive claim now traces to notes/research-notes.md (baseline v1.36).

Coverage additions (#6)

• New Flow 16 — What happens when the HPA scales a Deployment (flows renumbered to 17–28).
• ServiceAccount tokens and RBAC mechanics (Ch 2); kubectl exec/logs trace and
  ConfigMap/Secret propagation (Ch 4); upgrade order and version skew (Ch 10);
  the CronJob case study (Ch 5); 11 missing glossary terms and new quick-reference tables.

Principal/distinguished coverage (#7)

• Appendix D — The principal's lens: per-chapter zoom-outs, four decision tables,
  five critique prompts; Further reading is now Appendix E with the Borg lineage papers.
• Appendix C gains the Tier 4 — Judge rubric row.
• Part E: Chapter 11 — Fleet, Platform & Economics (Flows 29–30, the book's first
  Scenario design review) and Chapter 12 — Design Judgment: Lineage, Frontier & Capstones
  (six frontier bets with judgment, plus the "Redesign Kubernetes in 2026" and
  one-page platform-strategy capstones).
