   3. Template signer roles are automatically pre-mapped to the client's contacts (first role to primary contact, second role to co-buyer if present); agent can override any mapping before sending
   4. Text hints from the template appear as quick-fill suggestion buttons in the new document's PreparePanel
   5. "Templates" appears in the portal top nav and `/portal/templates` lists all active templates with form name, field count, and last-updated date

+<objective>
+Add "My Templates" tab to AddDocumentModal and extend POST /api/documents to apply a template — copying fields with fresh UUIDs and auto-mapping signer roles to client contacts.
+
+Purpose: Lets the agent start a new document from a saved template instead of a blank form, eliminating repetitive field placement on commonly-used PDFs.
+Output: Modified AddDocumentModal.tsx with two tabs, extended POST /api/documents route with documentTemplateId branch.

+Extend the JSON body parsing in the POST handler to also extract `documentTemplateId: string | undefined` from `body`.
+
+After the existing `if (!clientId || !name)` guard, add a new branch BEFORE the existing `formTemplateId` branch. The logic:
+
+```
+if (documentTemplateId) {
+  // 1. Fetch document template with its formTemplate relation
+  const docTemplate = await db.query.documentTemplates.findFirst({
+    where: eq(documentTemplates.id, documentTemplateId),

+  await copyFile(srcPath, destPath);
+
+  // 3. Copy fields with fresh UUIDs (D-07) — hints preserved verbatim (D-09)
+  const rawFields: SignatureFieldData[] = (docTemplate.signatureFields as SignatureFieldData[] | null) ?? [];
+  const copiedFields: SignatureFieldData[] = rawFields.map(f => ({
+    ...f,
+    id: crypto.randomUUID(),
+  }));
+
+  // 4. Role-to-email mapping (D-06)
+  // Collect unique role labels in order of first appearance
+  const seenRoles = new Set<string>();
+  const uniqueRoles: string[] = [];
+  for (const f of copiedFields) {
+    if (f.signerEmail && !seenRoles.has(f.signerEmail)) {
+      seenRoles.add(f.signerEmail);
+      uniqueRoles.push(f.signerEmail);
+    }
+  }
+
+  // Fetch client for email + contacts
+  const client = await db.query.clients.findFirst({
+    where: eq(clients.id, clientId),
+  });
+  const clientEmails = [
+    client?.email,
+    ...((client?.contacts as ClientContact[] | null) ?? []).map(c => c.email),
+  ].filter(Boolean) as string[];
+
+  const SIGNER_COLORS = ['#6366f1', '#f43f5e', '#10b981', '#f59e0b'];
+  const mappedSigners: DocumentSigner[] = uniqueRoles.map((role, i) => ({
+    email: clientEmails[i] ?? role,
+    color: SIGNER_COLORS[i % SIGNER_COLORS.length],
+  }));
+
+  // 5. Override formTemplateId for the DB insert
+  formTemplateId = docTemplate.formTemplateId;
+
+  // 6. Insert with fields and signers

+    signers: mappedSigners.length > 0 ? mappedSigners : null,
+  }).returning();
+
+  return Response.json(doc, { status: 201 });
+}
+```
+
+The existing `else` path (formTemplateId from form library) and file upload path remain completely unchanged.
+
+Add imports at top: `import { documentTemplates, clients } from '@/lib/db/schema';` and `import type { SignatureFieldData, ClientContact, DocumentSigner } from '@/lib/db/schema';`. The `clients` import is new; `documents` and `formTemplates` are already imported.
+
+Also parse `documentTemplateId` from body: add `let documentTemplateId: string | undefined;` alongside existing declarations, and in the JSON else block add `documentTemplateId = body.documentTemplateId;`.
+
+IMPORTANT: The template branch has its OWN db.insert + return, so the existing insert at the bottom of the function only runs for the non-template paths. Structure it so the template branch returns early.

+
+Add lazy fetch function — fetches templates only on first click of the My Templates tab:
+
+```typescript

+      .catch(console.error);
+  }
+}
+```
+
+Add mutual exclusivity to selection handlers:
+- In `handleSelectTemplate` (existing form-library handler): add `setSelectedDocTemplate(null);` at top
+- Add new handler for document template selection:
+```typescript
+const handleSelectDocTemplate = (t: DocumentTemplateRow) => {
+  setSelectedDocTemplate(t);
+  setSelectedTemplate(null);
+  setCustomFile(null);
+  setDocName(t.name);
+};
+```
+
+Extend `handleSubmit`:
+- Add a NEW branch at the top of the try block, before the existing `if (customFile)`:
+```typescript
+if (selectedDocTemplate) {
+  await fetch('/api/documents', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({

+    }),
+  });
+} else if (customFile) {
+  // ... existing custom file path unchanged
+} else {
+  // ... existing form library path unchanged
+}
+```
+
+Update the early-return guard in handleSubmit:
+```typescript
+if (!docName.trim() || (!selectedTemplate && !customFile && !selectedDocTemplate)) return;
+```
+
+Update the submit button disabled condition:
+```typescript
+disabled={saving || (!selectedTemplate && !customFile && !selectedDocTemplate) || !docName.trim()}
+```
+
+Render two tab buttons between the h2 heading and the search input. Use underline-style tabs matching the project's plain Tailwind approach:
+
+```tsx
+<div className="flex border-b mb-4">
+  <button
+    type="button"
+    onClick={() => setActiveTab('forms')}
+    className={`px-4 py-2 text-sm font-medium border-b-2 -mb-px ${

+  >
+    My Templates

+```
+
+Conditionally render tab content:
+- When `activeTab === 'forms'`: show the existing search input + form list + custom file upload section (ALL existing markup unchanged)
+- When `activeTab === 'templates'`: show the templates list:
+
+```tsx
+{activeTab === 'templates' && (

+  <action>
+**In DocumentPageClient.tsx:**
+
+1. Add import: `import type { SignatureFieldData } from '@/lib/db/schema';` (DocumentSigner is already imported).
+
+2. Add state for fields:
+```typescript
+const [fields, setFields] = useState<SignatureFieldData[]>([]);
+```
+
+3. Add useEffect to fetch fields on mount and when aiPlacementKey changes:
+```typescript
+useEffect(() => {
+  fetch(`/api/documents/${docId}/fields`)
+    .then(r => r.json())
+    .then((data: SignatureFieldData[]) => setFields(Array.isArray(data) ? data : []))
+    .catch(() => {});
+}, [docId, aiPlacementKey]);
+```
+
+4. Derive the hint for the selected field:
+```typescript
+const selectedFieldHint = selectedFieldId
+  ? fields.find(f => f.id === selectedFieldId)?.hint
+  : undefined;
+```
+
+5. Pass new prop to PreparePanel:
+```typescript
+<PreparePanel
+  // ... all existing props unchanged ...
+  selectedFieldHint={selectedFieldHint}
+/>
+```
+
+**In PreparePanel.tsx:**
+
+1. Add `selectedFieldHint?: string;` to the `PreparePanelProps` interface (after `onQuickFill`).
+
+2. Destructure it in the function signature: add `selectedFieldHint,` to the destructured props.
+
+3. In the Quick Fill section (inside the `{selectedFieldId ? (` branch), add a new chip AFTER the existing Client Email chip button (before the closing `</div>` of `space-y-1.5`):
+
+```tsx
+{selectedFieldHint && (
+  <button
+    type="button"
+    onClick={() => onQuickFill(selectedFieldId, selectedFieldHint)}
+    className="w-full text-left px-3 py-2 text-sm border rounded bg-white hover:bg-blue-50 hover:border-blue-300 transition-colors"
+  >
+    <span className="text-xs text-gray-400 block">Template Hint</span>
+    <span className="truncate block">{selectedFieldHint}</span>
+  </button>
+)}
+```
+
+This follows the exact same markup pattern as the existing Client Name / Property Address / Client Email chips. The prop is optional with no default — existing callers (DocumentPageClient without template-sourced documents) simply don't pass it, and `undefined` means no chip renders.

+  <name>Task 2: Human verification of full template-to-document flow</name>
+  <what-built>
+    Complete "Start from template" feature:
+    - My Templates tab in Add Document modal (Plan 01)
+    - Template apply with fresh field UUIDs and role mapping (Plan 01)
+    - Text hint quick-fill chips in PreparePanel (Plan 02 Task 1)
+    - Templates nav + list page (Phase 19, already live)
+  </what-built>
+  <how-to-verify>
+    Prerequisites: At least one saved template with fields and text hints must exist (created in Phase 19 testing).
+
+    1. Navigate to /portal/templates — verify the list page shows saved templates with form name, field count, and updated date (TMPL-16)
+    2. Verify "Templates" appears in the portal top nav (TMPL-15)
+    3. Go to a client profile page → click "Add Document"
+    4. Verify the modal shows two tabs: "Forms Library" and "My Templates" (TMPL-10)
+    5. Click "My Templates" tab → verify saved templates appear with name, form name, and field count
+    6. Select a template → verify the document name auto-fills with the template name
+    7. Click "Add Document" → verify the document is created and you're returned to the client page
+    8. Open the newly created document → verify fields are pre-loaded at the correct positions on the PDF (TMPL-11)
+    9. In PreparePanel, click a text field that has a hint → verify a "Template Hint" chip appears in the Quick Fill section alongside Client Name/Address/Email (TMPL-13)
+    10. Click the hint chip → verify the field is filled with the hint text
+    11. Click the "Forms Library" tab back in a new Add Document modal → verify the existing form library still works exactly as before (D-04)
+    12. (TMPL-14 — snapshot independence): Go to /portal/templates → edit the template (change a field position) → go back to the document created in step 7 → verify the document's fields are unchanged (still at original positions)
