Root Cause: CSS flex items default to min-height: auto, which prevents
flex-1 elements from shrinking below their content size. This caused
the FilesPanel to grow beyond its allocated space when the file tree
had many entries, pushing content off-screen.
Changes:
- FilesPanel.tsx: Added min-h-0 to root div to override min-height: auto
This allows flex-1 to actually constrain height and enable scrolling
- FileTree.tsx: Removed redundant overflow-auto and h-full from root div
The parent (FilesPanel flex-1 overflow-auto) already handles scrolling.
Nested scroll containers create height resolution issues.
The sidebar layout is now a clean single-scroll-container hierarchy:
Sidebar (flex flex-col, no overflow)
↳ SESSION (shrink-0, natural height)
↳ PROJECT (shrink-0, natural height)
↳ FilesPanel (flex-1 min-h-0) — constrained to available space
↳ Header (natural height)
↳ Scroll area (flex-1 overflow-auto) — THE scroll container
↳ FileTree (p-2 only) — no overflow, no h-full
↳ Footer (natural height)
- Add flex-1 to FilesPanel root div
- Sidebar is flex flex-col, FILES panel now grows to fill space
- SESSION and PROJECT panels remain natural height
- FILES panel expands into all remaining vertical space
This eliminates the gap below the FILES panel footer by making
the panel itself grow rather than just making the tree bigger.
- Change FilesPanel overflow-hidden to overflow-auto for scrolling
- Add max-h-80 to FileTree to limit height while allowing scroll
- Add select-none to FileTreeNode to prevent text selection
- Cursor-pointer already present for clickable indication
Now the file tree scrolls independently within the FILES panel,
and text cannot be selected during rapid clicking.
- Add isProcessingWorkOrder flag to track Agent work order processing
- Update onRequestWorkspaceMode with mode transition matrix validation
- Idle → User/Agent: Always allowed
- User → Agent: Always allowed (file editor checks for future)
- Agent → User: Only if !isProcessingWorkOrder
- All other transitions: Rejected with reason
- Extend RequestWorkspaceModeCallback with optional reason parameter
- Update frontend socket client to capture rejection reason
- Update handleWorkspaceModeChange to display rejection reason in toast
- Update WorkspaceModeIndicator to allow mode transitions per matrix
- Fix FilesPanel RW/RO indicator swap bug
- Document mode transition matrix and behavior in workspace-management.md
