# Dependency graph
requires:
  - phase: 08-agent-signature-schema
    provides: SignatureFieldType union type and getFieldType() helper
provides:
  - 5-token typed palette (Signature, Initials, Checkbox, Date, Text) with per-type colors
  - DragOverlay ghost with correct label and checkbox-appropriate dimensions (24x24 vs 144x36)
  - handleDragEnd writes correct type property to SignatureFieldData on drop
  - renderFields shows per-type label and border color for placed field overlays
affects: [10-02, 10-03]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "PALETTE_TOKENS array as single source of truth for id/label/color per SignatureFieldType"
    - "isDraggingToken stores active token id (string | null) instead of boolean for label-aware DragOverlay"
    - "Token id IS the SignatureFieldType — no mapping step needed in handleDragEnd"
    - "Checkbox 24x24pt special case — all other field types 144x36pt"

key-files:
  created: []
  modified:
    - teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/_components/FieldPlacer.tsx

key-decisions:
  - "PALETTE_TOKENS uses token id === SignatureFieldType value — active.id from dnd-kit can be cast directly to SignatureFieldType after Set membership check"
  - "Checkbox drops at 24x24pt (square); Signature/Initials/Date/Text drop at 144x36pt — matches plan spec exactly"
  - "fieldColor derived from PALETTE_TOKENS lookup for placed fields — resize handle corners and box-shadow also use fieldColor for visual consistency"
  - "agent-signature not included in palette (placed programmatically during document preparation, not by agent manually)"

patterns-established:
  - "PALETTE_TOKENS: single-source-of-truth array for all palette token metadata — add new token type here to propagate to palette, DragOverlay, and renderFields"
  - "validTypes Set guard before casting active.id to SignatureFieldType — defensive programming against future unknown drag sources"

requirements-completed:
  - FIELD-02
  - FIELD-03
  - FIELD-04

# Phase 10 Plan 01: Expanded Field Types — Palette and Field Placement Summary

**5-token typed palette (Signature/Initials/Checkbox/Date/Text) with per-type colors, type-aware DragOverlay ghost, and correct type property written to SignatureFieldData on drop**

## Performance

- **Duration:** 8 min
- **Started:** 2026-03-21T18:35:00Z
- **Completed:** 2026-03-21T18:43:00Z
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments
- Replaced single hardcoded "Signature" token with 5 typed draggable tokens (Signature blue, Initials purple, Checkbox green, Date amber, Text slate)
- Updated DragOverlay to show correct ghost label and dimensions per token (checkbox 24x24 square, others 144x36)
- handleDragEnd now writes `type: droppedType` and uses type-appropriate width/height (24x24pt for checkbox, 144x36pt for all others)
- renderFields now shows per-field label and border/background/shadow color driven by PALETTE_TOKENS lookup

## Task Commits

Each task was committed atomically:

1. **Task 1: Parameterize DraggableToken and add four new palette tokens** - `4140c22` (feat)
2. **Task 2: Update handleDragEnd and renderFields for typed field creation** - `1e92ca3` (feat)

**Plan metadata:** committed in final docs commit

## Files Created/Modified
- `teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/_components/FieldPlacer.tsx` - Extended with PALETTE_TOKENS, parameterized DraggableToken, typed handleDragEnd, and per-type renderFields

## Decisions Made
- Token id IS the SignatureFieldType value — `active.id` from dnd-kit is cast directly to `SignatureFieldType` after a `Set` membership guard. No extra mapping needed.
- Checkbox drops at 24x24pt (square); all other types at 144x36pt as specified.
- `agent-signature` intentionally excluded from palette — it is placed programmatically, not by the agent manually.
- `fieldColor` used for border, background tint, resize handle dots, and box-shadow on placed fields — consistent visual identity per field type.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Palette is ready with all 5 field types; Plans 02 and 03 can now read `field.type` to distinguish Checkbox/Date/Text render from Signature/Initials
- Prerequisite for prepare pipeline to render each field type correctly (Plan 02: PDF rendering, Plan 03: signing page rendering)
