 - **Phase:** Phase 2.5 - Step Library Foundation (In Progress)
 - **Backend:** Complete (25+ API endpoints, 100+ integration tests)
 - **Frontend:** Core features complete, Tree Editor functional

 - **Detailed status:** [CURRENT-STATE.md](CURRENT-STATE.md)
 
 ### What's In Progress
 
-- Custom step continuation flow refinements (Phase 2.5)
-- Tree forking from sessions with custom steps
+- Procedural flows reusability and run lifecycle improvements (Phase 2)
+- Step Library Frontend UI
 
 ### Recently Completed
 
+- Session sharing: ShareSessionModal, SharedSessionPage, MySharesPage, share links with copy/manage
+- Procedural editor UX: section headers as step type, "More Options" collapsible, URL intake field, tag input improvements
+- Type-aware routing: centralized `getTreeNavigatePath` helper, procedural resume support, safety redirects
 - Export improvements (Phases A-C): step cutoff, summary block, detail levels, editable preview, sensitive data redaction

 **13. Login redirect state format:** `navigate('/login', { state: { from: { pathname: '/path' } } })` — LoginPage expects `state.from.pathname` (object), NOT a plain string.
 
+**14. Type-aware routing for trees/sessions:** Always use `getTreeNavigatePath(treeId, treeType)` from `@/lib/routing` instead of hardcoding `/trees/:id/navigate`. Procedural flows use `/flows/:id/navigate`. Session resume passes `{ state: { sessionId } }`. TreeNavigationPage has a safety redirect for procedural trees.
+
+**15. Session sharing types:** `TreeSnapshot` extends `TreeStructure` but session snapshots from the API include extra fields like `tree_type`. Use `tree_snapshot?.tree_type` to determine flow type from session data.

 - **Type organization:** Create in `types/`, export from `types/index.ts`, import with `import type { T } from '@/types'`
 - **Scratchpad overlay:** `position: fixed`, `onOpenChange` callback for parent padding adjustment, `right-2` positioning
 - **Custom step flow:** `CustomStepModal` → `PostStepActionModal` → `ContinuationModal` → custom step view. Key state: `pendingStep`, `pendingContinuationNodeId`, `customBranchMode`, `branchOriginNodeId`. Use `findCustomStep()` not `findNode()` for custom step UUIDs.
+- **Session sharing:** `ShareSessionModal` manages share links, `SharedSessionPage` renders public/account views. Helper utils in `lib/sessionShare.ts`. Share URLs use `/shared/sessions/:token`.
+- **Procedural navigation:** `ProceduralNavigationPage` handles intake forms, step-by-step execution, and resume via `location.state.sessionId`. Uses `StepChecklist`, `StepDetail`, `ProgressBar`, `CompletionSummary` components.
+- **Routing helper:** Use `getTreeNavigatePath()` and `getTreeEditorPath()` from `@/lib/routing` for all tree/session navigation.
