+## M10 — UI polish (`frontend`)
+
+Resizable sidebar, full-width editor pages, icon top bar hosting the page
+actions and presence strip, plus a round of smaller refinements (footer
+connection status, dismissable dropdowns, named version contributors,
+substring search, label creation in the picker).
+**Exit**: everyday editing feels tidy on wide screens; all page actions
+live in the top bar.
+
+## M11 — Public API & MCP (`backend`, `frontend`, `docs`)
+
+Nextcloud backup target with in-app restore, personal access tokens,
+public REST API v1 (hand-maintained OpenAPI, instance + per-pond opt-in),
+built-in MCP endpoint exposing the same capabilities as tools.
+**Exit**: an external tool reads and writes pages with a PAT; an MCP
+client connects to `/api/mcp` and edits collab-safely.
+
+## M12 — Page hierarchy & knowledge graph (`backend`, `frontend`, `qa`)
+
+Hierarchical page tree (`parentId`, slugs stay flat), sidebar folder view
+vs. label view with pond default + per-user override, new pages nest
+under the open page, drag-and-drop reparenting + "Move to…" dialog,
+per-case delete semantics (promote children vs. trash subtree) with safe
+restore, API/MCP parity, pond-wide wikilink graph endpoint and an
+Obsidian-like knowledge-graph view with a local per-page graph panel
+(#106–#114).
+**Exit**: pages organize as a tree without breaking links, and the pond's
+wikilink structure is explorable as an interactive graph.
