Remove the active TreeShellIframeHost path and legacy env flag so rust_family only mounts the Rust/WASM DOM shell host.
Move legacy iframe host files to ignored recycle storage, clear tracked recycle cache entries, and update tree-domain design wording to the current no-iframe position.
Align filetree default active rows with doc:<documentId> and update the renderer artifact bridge contract to dom_wasm.
Open filetree mindmap assets inside the primary document pane so the sidebar root is not rebuilt during rapid mindmap/page switching.
Keep filetree active rows on doc:<documentId> and asset:<mindmapId>, shorten generated mindmap filenames, and preserve legacy index rows only as compatibility input.
Add task438-task445 browser smokes and close the 4-27/4-38/4-39/4-40 tree-domain bug records.
- add tree shell runtime artifact contracts and page/filetree/picker runtime reducers
- sink tree.subtree.move write operation through Rust and formalize command event plans
- harden file tree search projection contract and route thin-proxy boundaries
- record completed harness tasks and move design docs into process/done
