## 1. Update CLAUDE.md — CTO Session Completion Protocol

- [x] 1.1 Add a new "CTO SESSION COMPLETION PROTOCOL" section to CLAUDE.md under the CEO APPROVAL GATES section
- [x] 1.2 Document the mandatory completion confirmation rule: after any CEO-authorized action, CTO must post a follow-up to `#vpe-cto-approvals` with action, outcome, commit hash (if applicable), and resulting state
- [x] 1.3 Document the end-of-session summary rule: before closing, CTO must post a structured summary with three sections — Completed / Pending (authorized but not executed) / Requires CEO action next session
- [x] 1.4 Document the authorized-vs-done vocabulary rule: "authorized" = permission granted, "committed/completed/deployed" = action executed and confirmed — never interchangeable

## 2. Update README.md — Virtual CTO Responsibilities

- [x] 2.1 In Section 4.3 (Virtual CTO), add completion confirmation and end-of-session summary to the CTO responsibilities list
- [x] 2.2 Update the "Claude Session Startup (CTO Role)" block in Section 4.3 to include session-end checklist as a required step before closing

## 3. Update Engineering Workflow Doc

- [x] 3.1 In `docs/engineering/08-workflow.md`, add a section documenting the CTO session completion protocol — completion confirmation requirement, session-end checklist, and authorized-vs-done vocabulary — per the engineering-workflow spec delta
