Adds badge chips in the copilot chat input that reference selected diagram
elements, enabling scoped AI modifications. Includes code review fixes for
reduced-motion support, scope indicator, callback stability, schema validation,
neighbor limits, and buildSelectedContext test coverage (103 tests passing).

Add complete AI-powered diagram generation pipeline: natural language input
→ type inference → graph patch generation → validated canvas render with
ELK.js layout animation. Includes adversarial code review fixes for
diagramType enum validation, duplicate ID detection, tool part history
preservation, PATCH error handling, and graphData structural validation.

Add AI copilot chat panel to the diagram editor with streaming responses,
chat history persistence, and markdown rendering. Includes copilot API route,
diagram-aware system prompt, and schema with 15 passing tests.

Add node/edge selection visuals, drag-to-reposition with manuallyPositioned
persistence, multi-select via Shift+drag, selectedNodeIds store state for
Epic 3 badge integration, and code review fixes (dimmed+selected opacity,
single-source selection clearing, Map-based drag lookup).

Add the 6th and final core diagram type: flowcharts with standard
ISO 5807 shapes (process, decision, terminal, I/O, subprocess),
orthogonal edge routing with decision outcome labels, and ELK
layered auto-layout.
Code review fixes included: decision diamond ELK height corrected
(80→130px), icon rendering made conditional, data.color border
override added to all nodes, ELK sizing ternary refactored to
getNodeDimensions() helper, constants unified to lookup maps.

Adds four diagram type renderers completing the core diagram type suite:
- Story 2.4: E-R entity nodes with column tables, relationship edges with cardinality labels
- Story 2.5: Org chart person nodes with role/department tags, hierarchy edges
- Story 2.6: Architecture nodes (service, database, queue, load balancer, external), connection edges
- Story 2.7: Sequence participant nodes with lifelines + activation bars, fragment nodes,
3 custom edge types (sync/async/return), custom time-ordered layout (not ELK)
Story 2.7 includes code review fixes: computeLayout returns LayoutResult so enriched
sequence edges flow through useAutoLayout, activation bar computation in layout,
immutable layout function, self-message U-shaped loop rendering, sequence node size
tests in buildElkGraph.
476 tests passing across 29 test files, zero regressions.

Add first diagram type renderer with 9 custom BPMN node components,
3 edge types, compound ELK layout for pool/lane hierarchy, BFS path
highlighting on node click, and group container rendering. Includes
review fixes: integrated compound layout into computeLayout pipeline,
wired BFS highlighting via onNodeClick handler, replaced hardcoded
SVG colors with CSS custom properties for dark mode, and added 4
handles to all event nodes for multi-direction layout support.
81 web tests passing (31 new), no regressions.

Add automatic diagram layout via ELK.js running in a dedicated Web Worker.
Nodes animate smoothly (200ms ease-out) to computed positions using the
Sugiyama/layered algorithm. Includes layout direction controls (DOWN/RIGHT/
LEFT/UP), edge routing modes (orthogonal/splines/polyline), 200-node soft
cap warning, single-flight race condition protection, and 10s worker timeout.

Replace the placeholder diagram editor with a professional Studio layout featuring
an interactive @xyflow/react canvas, unified graph data model with bidirectional
converters, Zustand state management, and oklch design tokens. Includes 25 unit
tests for converters and store, with all code review fixes applied.

Add sortOrder column to diagrams, extend PATCH endpoint with projectId
and sortOrder fields, add POST /diagrams/reorder bulk endpoint with
ownership verification and duplicate ID validation. Enhance RecentList
with lastAiMessage preview subtitle. Implement @dnd-kit drag-and-drop
in ProjectTree sidebar with cross-project moves, intra-project reorder,
optimistic updates, drag overlay, drop indicators, and keyboard/pointer
sensor support. Context-aware GET ordering: sortOrder for project views,
updatedAt for recent/all views. 141 tests pass.

Add PATCH and DELETE endpoints with ownership checks (403 vs 404),
inline rename on DiagramCard and editor header, delete confirmation
dialog, and differentiated error states for forbidden/not-found.

Add project CRUD API (GET/POST/PATCH/DELETE) with ownership checks and
transactional delete. Add diagram list filtering by projectId and
unorganized query params with typed Zod query schema for Hono RPC
type safety. Create DiagramSidebar with Projects tree (expand/collapse,
inline rename) and Recent tab. Add project picker to CreateDiagramDialog.
Includes 15 schema validation tests (107 total passing).

Add diagram/project DB schema, CRUD API, dashboard pages with grid/card/
empty state, create dialog with type selector, editor placeholder, and
26 schema validation tests. Includes code review fixes: soft-delete
filter on GET /:id, error handling, keyboard accessibility, type-safe
API response types, and error states on pages.
