with sequential execution and collected results
- New MCP tool 'batch' accepts a JSON array of request objects
- Nested batches rejected with clear error message
- Updated AGENTS.md with .app rebuild requirement
- Undo walks to parent node in history tree, redo follows
last-active-child for correct branch tracking after forks
- HistoryTree tracks branch recency via last_active_child field,
updated on push() and checkout() path transitions
- SVG files can be dragged from Finder onto the canvas window
- Edit menu with Undo/Redo items, command palette entries
- 3 new tests: undo, redo, redo-after-fork branch behavior
- 29 tests passing, clippy clean
- Boolean operations (union, intersection, difference, xor) via i_overlay
with Path shape rendering using earcutr triangulation
- Visual undo tree with branching history, checkout, and fork (Cmd+H)
using Arc-based snapshots for structural sharing
- Consistent Augmented Canvas branding across app title, MCP server,
CLI help text, and error messages
- macOS .app bundle script and Info.plist for Finder integration
- New MCP tool: boolean_op for agent-driven shape composition
- 26 tests passing (5 boolean, 6 history, 15 existing)
Sessions now track who created them (Human vs Agent with name),
optional descriptions, and creation timestamps. Agents can create
and update sessions via WebSocket and MCP. ListSessions supports
sorting by name, created_at, created_by, or element_count.
New MCP tools: create_session, update_session. Updated list_sessions
with sort_by/sort_order params. Tab bar shows robot icon for
agent-created sessions with hover tooltips.
