+# Phase 12.1 Plan 01: Per-Field Text Fill and Click-to-Select Summary
+
+**One-liner:** Field-ID-keyed UUID text drawing in preparePdf with Strategy A/B removed; click-to-select inline input overlay on text fields in FieldPlacer; prop chain PdfViewerWrapper -> PdfViewer -> FieldPlacer wired and ready for Plan 02.
+
+## Tasks Completed
+
+| # | Task | Commit | Files |
+|---|------|--------|-------|
+| 1 | Replace positional text fill with field-ID-keyed lookup in preparePdf | df02a1e | prepare-document.ts |
+| 2 | Add optional text-edit props to PdfViewerWrapper, PdfViewer, FieldPlacer click-to-select | eaf377d | PdfViewerWrapper.tsx, PdfViewer.tsx, FieldPlacer.tsx |
+
+## What Was Built
+
+### Task 1: preparePdf field-ID-keyed text fill
+
+Replaced the broken positional text assignment pipeline in `prepare-document.ts`:
+
+- **Removed** AcroForm Strategy A: `pdfDoc.getForm()`, `form.getTextField()`, `form.flatten()`, `acroFilledKeys`, `hasAcroForm`
+- **Removed** positional sort loop: `remainingEntries`, `textFields_sorted`, `fieldConsumedKeys`, `textFields_sorted.forEach()`
+- **Removed** Strategy B top-of-page stamp: `unstampedEntries`, `firstPage.drawText(`${key}: ${value}`, ...)`
+- **Added** Phase 12.1 field-ID loop: `textFields[field.id]` direct UUID lookup, draws at `field.x+4, field.y+4` with font 6-11pt clamped to field height
+
+The `textFields` parameter type (`Record<string, string>`) is unchanged — backward-compatible. Calling routes pass `body.textFillData` which will now be `{ [fieldId]: value }` once Plan 02 wires the UI.
+
+### Task 2: Optional prop chain and click-to-select
+
+**PdfViewerWrapper.tsx** and **PdfViewer.tsx:** Added 4 optional props to each and forwarded them down the chain:
+- `selectedFieldId?: string | null`
+- `textFillData?: Record<string, string>`
+- `onFieldSelect?: (fieldId: string | null) => void`
+- `onFieldValueChange?: (fieldId: string, value: string) => void`
+
+PdfViewer also calls `onFieldSelect?.(null)` on Prev/Next page button clicks to deselect on page change.
+
+**FieldPlacer.tsx:**
+- Extended `FieldPlacerProps` with the 4 new optional props
+- `DroppableZone` now accepts `onClick?: (e: React.MouseEvent<HTMLDivElement>) => void` — background clicks deselect via `onFieldSelect?.(null)` when target is not inside `[data-field-id]`
+- Per-field div gets `onClick` handler: text fields call `onFieldSelect?.(field.id)` with `e.stopPropagation()` to prevent DroppableZone deselect; non-text fields call `onFieldSelect?.(null)`
+- `renderFields()` computes `isSelected = selectedFieldId === field.id` and `currentValue = textFillData?.[field.id] ?? ''`
+- Text field content: `isSelected` shows `<input data-no-move autoFocus>` with transparent styling; not selected shows value or label in truncating `<span>`
+- Cursor set to `'text'` for text fields (vs `'grab'` for others)
+- BoxShadow ring `0 0 0 2px {fieldColor}66` when text field is selected
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Verification
+
+- `npx tsc --noEmit` passes with zero errors
+- `prepare-document.ts` contains `textFields[field.id]` and does NOT contain `remainingEntries`, `unstampedEntries`, `fieldConsumedKeys`, `getForm()`, or `form.flatten()`
+- `FieldPlacer.tsx` exports `FieldPlacer` with all 4 new optional props in `FieldPlacerProps`
+- `PdfViewerWrapper.tsx` and `PdfViewer.tsx` accept and forward the 4 new optional props
+- Plan 02 can wire `selectedFieldId`, `textFillData`, `onFieldSelect`, `onFieldValueChange` state from `DocumentPageClient` without any additional changes to these files
+
+## Self-Check: PASSED
+

+- [x] `FieldPlacer.tsx`, `PdfViewer.tsx`, `PdfViewerWrapper.tsx` exist and modified
