 Phase: 12.1 (Per-Field Text Editing and Quick Fill)
-Plan: 1 of 2 in phase 12.1 — COMPLETE
-Status: Phase 12.1 Plan 01 complete — field-ID-keyed text fill in preparePdf; click-to-select inline input in FieldPlacer; prop chain PdfViewerWrapper->PdfViewer->FieldPlacer ready for Plan 02 wiring
-Last activity: 2026-03-21 — Phase 12.1 Plan 01 complete: Strategy A/B removed from preparePdf; UUID-keyed text drawing; optional text-edit props threaded through component chain; click-to-select inline input interaction in FieldPlacer.
+Plan: 2 of 2 in phase 12.1 — AWAITING HUMAN VERIFICATION (checkpoint Task 3)
+Status: Phase 12.1 Plan 02 automated tasks complete — selectedFieldId + textFillData lifted to DocumentPageClient; QuickFillPanel in PreparePanel; TextFillForm deleted; awaiting human browser verification of full per-field text editing and quick-fill flow
+Last activity: 2026-03-21 — Phase 12.1 Plan 02: state bridge wired in DocumentPageClient; TextFillForm replaced with QuickFillPanel; handleFieldValueChange and handleQuickFill both reset previewToken; zero TSC errors.

@@ -113,6 +114,9 @@ Recent decisions affecting v1.1 work:
 - [Phase Phase 12.1-01]: preparePdf text fill is now keyed by SignatureFieldData.id (UUID) — direct lookup replaces positional sort; AcroForm Strategy A and Strategy B top-of-page fallback both removed
 - [Phase Phase 12.1-01]: FieldPlacer click-to-select uses onClick (fires only on no-drag clicks due to MouseSensor distance:5 threshold) — onPointerDown move handler is preserved and unaffected
 - [Phase Phase 12.1-01]: data-no-move attribute on the inline input onPointerDown stops move handler activation — consistent with existing delete button and resize handle pattern
+- [Phase 12.1-02]: textFillData starts as {} in DocumentPageClient — NOT seeded from clientPropertyAddress; old label-keyed seeding ({ propertyAddress: clientPropertyAddress }) is removed; quick-fill makes it trivial to insert the value once a field is selected
+- [Phase 12.1-02]: handleFieldValueChange and handleQuickFill are separate useCallback functions that both call setPreviewToken(null) — satisfies TXTF-03 staleness reset on every text change
+- [Phase 12.1-02]: defaultEmail reused for Client Email quick-fill button — already a PreparePanel prop (used for recipients pre-fill); no new prop needed (per research Pitfall 3)
