Pathology Workflow Editor Reuse

What this folder reuses from worklist-editor, what it adds, and the explicit non-modification boundary.

Reuse Principle

worklist-editor is not forked. It is composed. We import:

• 5 hooks (no copies, no wrappers — direct imports)
• 1 type module (types/index.ts)
• 2 components (DepartmentSelector, NodeConfigDrawer)

If the upstream worklist-editor changes (new prop, new behaviour), this editor inherits the change for free.

What We Reuse

Upstream symbol	Imported as	Used in	Rationale
useDepartmentSelection	useDepartmentSelection	pathology-workflow-editor/index.tsx	Same clinic/sub-clinic picker
useWorkflowManagement	useWorkflowManagement	same	Loads workflow_templates rows for pathology dept
useRoleWorklistConfig	useRoleWorklistConfig	same	Per-role visibility (Pathologist sees Sign-out, Tech sees Slide Prep)
useWorkflowGraph	useWorkflowGraph	same	Builds parent-child graph from edges for canvas
useQuickSetup	useQuickSetup	same	“Generate standard pathology presets” button
WorkflowNode type	WorkflowNode	types/index.ts (extended)	We extend with pathologyMeta
WorkflowEdge type	WorkflowEdge	same	Unchanged
``	``	top of editor page	Same UX as worklist-editor
``	``	right-side drawer	We pass extraTabs={PATHOLOGY_PANELS}

All imports route through:

import {
  useDepartmentSelection,
  useWorkflowManagement,
  useRoleWorklistConfig,
  useWorkflowGraph,
  useQuickSetup,
} from '@/common/components/medical/builder/worklist-editor/hooks';

(We rely on the existing folder; no barrel changes needed.)

What We Add (Pathology-Specific)

What We Do NOT Modify

• worklist-editor/index.tsx — untouched
• worklist-editor/components/* — untouched
• worklist-editor/hooks/* — untouched
• worklist-editor/types/* — untouched (we extend in our own types file)
• main-flow-editor/components/workflow/types.ts (BlockEnum) — untouched (the deep-mock direction would add to it later; for the demo mock the pathology node types are local to this folder)
• packages/medical-kit/src/medical-worklist/defaults/pathology-*.json — untouched (the editor reads them as the seed source)

If the demo proves the value, the next step is upstreaming pathology node types into BlockEnum so they’re first-class in main-flow-editor too. That’s tracked in integration-guide.md under “Promotion to First-Class”.

Drawer Extension Pattern

NodeConfigDrawer accepts an extraTabs prop (added as part of this work — see the type extension in panels/index.ts). The pathology editor passes:

<NodeConfigDrawer
  open={drawerOpen}
  editingNode={editingNode}
  workflowNodes={workflowNodes}
  selectedRole={selectedRole}
  customConfigs={customConfigs}
  queueConfigs={queueConfigs}
  onSave={handleSaveNodeConfig}
  onSwitchToActionTab={handleSwitchToActionTab}
  onPreviewNode={handlePreviewNode}
  extraTabs={getPathologyTabs(editingNode)}  // ← pathology-only injection
/>

getPathologyTabs(nodeId) returns the 3-4 pathology panels relevant to the node type. For non-pathology nodes (if the user opens this editor on a clinic dept that mixes node types), extraTabs returns [] and the drawer renders unchanged.

NOTE on NodeConfigDrawer: at the time of writing, NodeConfigDrawer does not yet expose extraTabs. The clean upstream change is a 5-line additive prop. Until that lands, the pathology editor renders its own drawer (PathologyConfigDrawer.tsx — a thin copy of NodeConfigDrawer with the extra tabs hardcoded). When the upstream prop lands, delete PathologyConfigDrawer.tsx and switch to ``.

This keeps the change additive — a TODO sticker, not a fork.
