# Dependency graph
requires:
  - phase: 11-agent-saved-signature-and-signing-workflow
    provides: AgentSignaturePanel pattern, agent_signature_data column on users, /api/agent/signature route
provides:
  - agentInitialsData TEXT column on users table with migration 0009_luxuriant_catseye.sql
  - GET/PUT /api/agent/initials routes with auth guard and 50KB size limit
  - AgentInitialsPanel component (80px canvas, save/update/thumbnail flow)
  - Profile page Agent Initials section below existing Agent Signature section
  - 'agent-initials' as 7th token in FieldPlacer palette (orange #ea580c)
  - 'agent-initials' added to SignatureFieldType union
  - isClientVisibleField() updated to exclude both agent-signature and agent-initials
affects:
  - 11.1-02 (plan 02 uses agentInitialsData in preparePdf embedding)
  - signing workflow (isClientVisibleField security boundary)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "AgentInitialsPanel is a clone of AgentSignaturePanel with 80px canvas, /api/agent/initials endpoint, and initials-specific labels — minimal diff from template"
    - "isClientVisibleField() guards all agent-owned field types (agent-signature, agent-initials) from client signing session"

key-decisions:
  - "Migration auto-named 0009_luxuriant_catseye.sql by drizzle-kit; content is correct ALTER TABLE users ADD COLUMN agent_initials_data text"
  - "AgentInitialsPanel clones AgentSignaturePanel pattern exactly — same DPR canvas init, signature_pad, save/error/loading state — only endpoint, canvas height (80px vs 140px), and labels differ"
  - "Agent Initials palette token is orange #ea580c — groups visually with red agent-signature as agent-owned while remaining distinct from client-visible tokens"
  - "isClientVisibleField() now guards both agent-signature and agent-initials — security boundary complete for Plan 02 embedding work"

patterns-established:
  - "Agent-owned field types (agent-signature, agent-initials) are excluded from client signing session via isClientVisibleField() — add new agent types here when needed"
  - "AgentXxxPanel clone pattern: same component structure, different API endpoint, different canvas height, different label strings — no shared abstraction needed"

# Phase 11.1 Plan 01: Agent Initials Storage and UI Summary

**agentInitialsData column + GET/PUT API route + AgentInitialsPanel (80px canvas) + orange palette token + isClientVisibleField() security boundary for agent-initials**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-21T20:57:44Z
- **Completed:** 2026-03-21T20:59:46Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments
- DB schema extended: agentInitialsData TEXT column on users table, migration 0009_luxuriant_catseye.sql applied
- GET/PUT /api/agent/initials routes created with auth guard, data:image/png validation, and 50KB size limit
- AgentInitialsPanel component created (clone of AgentSignaturePanel with 80px canvas height, /api/agent/initials endpoint, initials-specific labels)
- Profile page updated to fetch and render both agentSignatureData and agentInitialsData in a second section below Agent Signature
- FieldPlacer palette extended with orange Agent Initials token (7th entry) and validTypes updated
- isClientVisibleField() now guards both agent-signature and agent-initials from client signing session

## Task Commits

Each task was committed atomically:

1. **Task 1: DB migration, API routes, schema type updates for agent initials storage** - `33f499c` (feat)
2. **Task 2: AgentInitialsPanel component, profile page section update, FieldPlacer token** - `d9f618f` (feat)

**Plan metadata:** (included in final docs commit)

## Files Created/Modified
- `teressa-copeland-homes/src/lib/db/schema.ts` - Added agentInitialsData column, 'agent-initials' to SignatureFieldType, updated isClientVisibleField()
- `teressa-copeland-homes/drizzle/0009_luxuriant_catseye.sql` - ALTER TABLE users ADD COLUMN agent_initials_data text
- `teressa-copeland-homes/src/app/api/agent/initials/route.ts` - GET/PUT endpoints for reading and writing agent initials
- `teressa-copeland-homes/src/app/portal/_components/AgentInitialsPanel.tsx` - Client component with 80px signature_pad canvas, save/update/thumbnail flow
- `teressa-copeland-homes/src/app/portal/(protected)/profile/page.tsx` - Fetches agentInitialsData, renders AgentInitialsPanel below signature section
- `teressa-copeland-homes/src/app/portal/(protected)/documents/[docId]/_components/FieldPlacer.tsx` - Added agent-initials orange token and to validTypes Set

## Decisions Made
- Migration auto-named 0009_luxuriant_catseye.sql by drizzle-kit (consistent with 0008_windy_cloak.sql pattern)
- AgentInitialsPanel clones AgentSignaturePanel exactly — same DPR canvas init, signature_pad, save/error/loading state; only endpoint, canvas height (80px), and labels differ
- Orange #ea580c chosen for agent-initials token — groups with red #dc2626 agent-signature as "agent-owned" fields while visually distinct
- isClientVisibleField() guards both agent-signature and agent-initials from client signing session — security boundary is complete for Plan 02 embedding work without further changes to this function

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- drizzle-kit migrate required explicit DATABASE_URL env var (not loaded from .env.local automatically when run via npm script without dotenv setup) — resolved by passing DATABASE_URL inline; migration applied successfully

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

## Next Phase Readiness
- Plan 02 can now implement preparePdf() embedding of agent initials without any further schema, API, or UI work
- agentInitialsData is stored in the same column format as agentSignatureData (base64 PNG dataURL) — embedding code can follow the exact same PDFImage embed-once-draw-many pattern from Phase 11 Plan 02
- isClientVisibleField() security boundary is already enforced — agent-initials fields will not appear in client signing sessions
