dsh-plugin-message-edit v0.1.0

First standalone release of Edit and resend for DeepSeek Harness.

• Adds a pencil action to the latest committed user message.
• Forks a clean child session before the edited turn.
• Restores the original text as a draft without changing the source session.
• Declares conversation.chat.user-actions, session.fork.beforeSeq, and session.fork.blank host requirements.
• Fails closed on incompatible hosts and safely disables itself on legacy slot runtimes.
• Ships committed browser artifacts with no install lifecycle scripts.

Verified by GitHub CI on Node 22 and Node 24 and by install/edit/uninstall testing from a fixed GitHub commit SHA.
