Worksheet v0.2.1

Worksheet v0.2.1

Rebrand: the book is now titled Kubernetes Internals Worksheet — "Interview" dropped from the README, the STYLE contract, and the PDF cover kicker. Content is unchanged from v0.2.0 (12 chapters, 30 flows, appendices A–E).

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).
