Codex Companion v0.4.40

Codex Companion v0.4.40

This public preview moves Codex Companion beyond a chat-only panel toward a first-stage MarginNote Knowledge Agent OS.

Highlights

• Added first-stage Live MN Object Kernel, Source Registry action evidence, External Automation Gateway, Skill Runtime v2, and Verification Agent.
• Added Knowledge OS shell anchors in the WebView so stale chat-only runtimes are detected by doctor and single-document acceptance checks.
• Improved transactional native edit evidence by separating note/card rollback and residual proof.
• Upgraded workflow and skill runtime evidence with dry-run-first plans, next/resume actions, and verification reports.
• Updated bilingual README, product spec, user manual, release matrix, and current release audit for the v0.4.40 architecture.
