# Dependency graph
requires:
  - phase: 08-type-discriminant-and-signing-boundary
    provides: "agent-signature SignatureFieldType already in schema; isClientVisibleField() filter"
  - phase: 10-expanded-field-types-end-to-end
    provides: "FieldPlacer PALETTE_TOKENS pattern; SignatureFieldType validTypes set"
provides:
  - "agentSignatureData TEXT column on users table (migration 0008_windy_cloak.sql)"
  - "GET/PUT /api/agent/signature endpoints — read/write agent signature dataURL"
  - "AgentSignaturePanel component — draw/save/update canvas flow with thumbnail"
  - "/portal/profile page — server component rendering AgentSignaturePanel"
  - "PortalNav Profile link — /portal/profile nav entry"
  - "FieldPlacer agent-signature palette token — red draggable 'Agent Signature' token"
affects:
  - 11-02-agent-signing-workflow
  - 12-document-preview

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Server component fetches agentSignatureData from DB, passes as initialData prop to client component"
    - "AgentSignaturePanel: isDrawing state gates canvas mount; savedData state shows thumbnail"
    - "signature_pad DPR initialization pattern from SignatureModal.tsx reused for canvas setup"
    - "PUT /api/agent/signature validates data:image/png;base64, prefix and 50KB size limit"

  created:
    - teressa-copeland-homes/src/lib/db/schema.ts (agentSignatureData column added)

key-decisions:
  - "Migration file generated as 0008_windy_cloak.sql (drizzle auto-names files) — content is correct: ALTER TABLE users ADD COLUMN agent_signature_data text"
  - "AgentSignaturePanel is fully self-contained — no external state management; fetch/save within component"
  - "Profile page uses redirect('/agent/login') (consistent with portal auth pattern) if session missing"
  - "Agent Signature palette token is red #dc2626 to distinguish from client-facing field types"

patterns-established:
  - "Profile page pattern: server fetch agentSignatureData, pass to client panel as initialData prop"
  - "Canvas signature panel: useEffect gates on isDrawing, cleans up SignaturePad on unmount/toggle"

# Phase 11 Plan 01: Agent Saved Signature Storage and UI Summary

**agentSignatureData TEXT column on users + GET/PUT API + AgentSignaturePanel draw/save/thumbnail + /portal/profile page + red Agent Signature palette token in FieldPlacer**

## Performance

- **Duration:** 8 min
- **Started:** 2026-03-21T20:05:00Z
- **Completed:** 2026-03-21T20:13:00Z
- **Tasks:** 2
- **Files modified:** 7

## Accomplishments
- DB schema updated with agentSignatureData column and migration applied to postgres
- Secure GET/PUT API routes for reading/writing agent signature with auth guard and input validation
- AgentSignaturePanel client component with signature_pad canvas, save/update/thumbnail flow
- /portal/profile server page fetching saved signature and rendering the panel
- PortalNav gains Profile link; FieldPlacer gains red "Agent Signature" draggable token

## Task Commits

Each task was committed atomically:

1. **Task 1: DB migration and API routes for agent signature storage** - `e07ed30` (feat)
2. **Task 2: AgentSignaturePanel, profile page, PortalNav link, FieldPlacer token** - `f383f91` (feat)

## Files Created/Modified
- `teressa-copeland-homes/src/lib/db/schema.ts` - Added agentSignatureData TEXT column to users table
- `teressa-copeland-homes/drizzle/0008_windy_cloak.sql` - Migration: ALTER TABLE users ADD COLUMN agent_signature_data text
- `teressa-copeland-homes/drizzle/meta/0008_snapshot.json` - Drizzle schema snapshot
- `teressa-copeland-homes/src/app/api/agent/signature/route.ts` - GET/PUT endpoints with auth guard + validation
- `teressa-copeland-homes/src/app/portal/_components/AgentSignaturePanel.tsx` - Draw/save/update canvas component
- `teressa-copeland-homes/src/app/portal/(protected)/profile/page.tsx` - Server component profile page
- `teressa-copeland-homes/src/app/portal/_components/PortalNav.tsx` - Added Profile navLink
- `teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/_components/FieldPlacer.tsx` - Added agent-signature palette token

## Decisions Made
- Migration auto-named `0008_windy_cloak.sql` by drizzle-kit (naming is non-deterministic); content is the correct ALTER TABLE statement
- AgentSignaturePanel is fully self-contained with local state — no external state management or context needed
- Profile page uses `redirect('/agent/login')` if session missing (consistent with other portal pages)
- Agent Signature palette token color is red `#dc2626` to visually distinguish it from client-facing field types

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- Migration command `npm run db:migrate` failed with "DATABASE_URL: undefined" because the .env.local file is not auto-loaded by drizzle-kit in this environment. Fixed by running with explicit `DATABASE_URL=... npm run db:migrate`. Migration applied successfully.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Plan 01 artifacts complete: DB column, API routes, AgentSignaturePanel, profile page, nav link, FieldPlacer token
- Plan 02 can now wire up preparePdf() to read agentSignatureData from users and embed it on agent-signature fields
- No blockers for Plan 02
