Phase 11.1 Plan 02: Agent Initials Prepare Pipeline Summary

preparePdf() extended with embed-once-draw-many agentInitialsImage; prepare route fetches initials in same DB query and guards 422 on missing initials — agent initials now baked into prepared PDFs

Performance

• Duration: 4 min
• Started: 2026-03-21T21:02:18Z
• Completed: 2026-03-21T21:06:00Z
• Tasks: 2
• Files modified: 2

Accomplishments

• preparePdf() gains 6th optional param agentInitialsData; embeds PNG once before field loop and draws at each agent-initials field coordinate
• prepare route fetches both agentSignatureData and agentInitialsData in a single DB query (one round-trip, not two)
• 422 guard returns { error: 'agent-initials-missing' } when agent-initials fields present but no initials saved — no silent failure
• Existing 'initials' (client-initials) branch and 'agent-signature' branch left completely untouched — zero regressions

Task Commits

Each task was committed atomically:

1. Task 1: preparePdf() — add agentInitialsData param and embed at agent-initials field coordinates - fae1cf1 (feat)
2. Task 2: prepare route — fetch agentInitialsData in same query, 422 guard, pass to preparePdf - c876579 (feat)

Plan metadata: (included in final docs commit)

Files Created/Modified

• teressa-copeland-homes/src/lib/pdf/prepare-document.ts - Added agentInitialsData 6th param, embedPng block before loop, agent-initials drawImage branch in loop
• teressa-copeland-homes/src/app/api/documents/[id]/prepare/route.ts - Added agentInitialsData to DB query columns, agentInitialsData variable, hasAgentInitialsFields 422 guard, agentInitialsData as 6th arg to preparePdf()

Decisions Made

• agentInitialsData defaults to null (6th optional param) so existing call sites compile unchanged until Task 2 updates the prepare route
• Placed agent-initials drawImage branch immediately after agent-signature branch — consistent ordering, client-initials branch untouched
• DB query extended via columns selector (not a second query) — single round-trip matches Phase 11 Plan 02 pattern

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Plan 03 is pure human E2E verification: visit profile to draw/save initials, place agent-initials field on a document, prepare it, verify PNG embedded at correct coordinates in the output PDF
• 422 guard ready to test: prepare with no initials saved should return { error: 'agent-initials-missing' }
• Client-initials regression check: purple Initials placeholder still draws at prepare time; client still prompted during signing
