Persist PageTree expand state via control-plane view-state and align
chevron/DOM with restored expansion; keep Sidex-style shallow page-tree
scan and drop the unused recursive scanner that only added cargo noise.
Add password vault workbench routes/runtime/skill/CLI, split page_ai_pi
into a module package, and retire Hermes/ACP/OpenHub recycle + root
harness evidence from the index while gitignoring recycle and local
diag dumps.
Archive superseded design/bugs docs under old/, point architecture at
ARCHITECTURE.md, and refresh smokes for Pi S1–S7, vault, and editor
regressions so the working tree can stay clean.
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.
