Agent Mail UI adds an optional mailbox surface over an existing Agent Mail MCP connection. Use the right panel with better-sidebar, or the standalone Mail drawer without it.
This release fixes Quote targeting when switching conversations, tool-result running/error/success cards, acknowledged-mail unread counts, and task Done/Ack interactions. It does not start another MCP child or perform human approvals.
Target: DSH/MCP client 0.1.1-rc.2, companion @dff652/dsh-agent-mail@0.1.1; optional better-sidebar 0.12.2. Existing rc.6 installations need a separately validated core/MCP migration.
Validation: Node 22/24 each 98/98; exact eight-file archive; disposable Web/headless install/remove; real MCP; Firefox/Chrome fixtures; real standalone in both browsers and better-sidebar in Chrome. Tool-card owners are synthetic DSH-contract fixtures; model-driven dispatch is not claimed.
Download the archive and verify it against SHA256SUMS before installation. See the acceptance record and upgrade plan.
